屈折率測定装置および濃度測定装置

【課題】 従来、試料の濃度や透明薄膜の厚さを測定する手段として、低コヒーレンス干渉法などによってその屈折率を求める方法が挙げられる。しかし、従来の低コヒーレンス干渉法における光学測定においては、機械的動作が必要となるため、非常に高精度を必要とする機器の調整が必要で、更にステージを移動させるという機械的な動作が生じるため、その際に必ず振動が生じてしまい、測定精度に大きな影響を及ぼしてしまう。 【解決手段】 機械的動作を液晶素子による光変調などによる電気的な動作に置き換えることによって、非常に高精度を必要とする機器の調整が不要となり、また、振動などの影響がないため高精度の測定が可能となる。また、これまで、ミラーを可動とし、ミラーによる反射光を参照光としていたため機器の配置の制約が大きかったが、透過光線を利用できる液晶素子を用いることにより、小型化など様々な状況に応じた装置構成が可能となる。 【選択図】 図１

【課題】 複数のＬＥＤブロックを有するＬＥＤ発光ユニットを備えたＬＥＤ発光装置において、ＬＥＤ発光ユニットの発光面に対して、口金やレンズ等の光学装置の位置を正しく合わせ込むことが望まれていた。 【解決手段】 基板上に、複数のＬＥＤ素子を直列接続したＬＥＤブロックを複数個整列配設し、前記複数のＬＥＤブロックを並列接続して共通の電源電圧で点灯駆動するＬＥＤ発光ユニットにおいて、前記ＬＥＤブロックを構成するＬＥＤ素子の一部に、他のＬＥＤ素子より発光開始電圧の低い位置検出用のＬＥＤ素子を配設することにより、前記共通の電源電圧を規定値より低い電圧値で供給することによって、前記位置検出用のＬＥＤ素子を含む位置検出ＬＥＤブロックのみを点灯させる。 【選択図】 図１

尿成分測定装置

【課題】 便座型尿糖計においては、頻繁に尿測定を行うので、導管の汚れによって流れが悪くなり測定時間が遅くなったり詰まってしまう原因や、あるいは測定装置内は汚れによって測定誤差を生じる原因となる。 【解決手段】 採尿部１と導管５の間に成分除去手段３を設けて尿糖測定成分を測定することにより、導管５，導管６３内の汚れや測定容器５５内の汚れを軽減することができる。さらに、成分除去手段３の通過時間をバルブ２を制御して効率のよい汚れの軽減が可能である。これにより、メンテナンス作業を軽減し、測定誤差を軽減することができるので、高精度測定が可能となる。旋光度測定や光吸収測定などの光学測定方式では光透過率を保持するという面で特に有効である。 【選択図】 図２

Light-emitting device

A light-emitting device (10) includes a plurality of light-emitting areas (10a, 10b and 10c), and each of the light-emitting areas (10a, 10b and 10c) includes a first light-emitting block (3) and a second light-emitting block (4). Each respective first light-emitting blocks (3) include a plurality of first light-emitting elements (A1, A2, or A3), which are connected in series, and each respective second light-emitting blocks (4) include a plurality of second light-emitting elements (B1, B2, or B3), which are connected in series. The number of first light-emitting elements in each respective first light-emitting blocks (3) is the same with one another of the first light-emitting blocks (3), and the number of second light-emitting elements in each respective second light-emitting blocks (4) is the same with one another of the second light-emitting blocks (4).

光変調装置

【課題】従来の液晶素子を使った旋光成分の濃度測定装置においては、旋光用液晶素子全体に電圧を徐々に印加することによって旋光物質の濃度を測定することができる。しかし、この方法により微小濃度を測定する場合は、電圧印加のステップ幅を微小にしなければならない。また、液晶がそのステップ幅に応じた微小旋光特性を示すことは困難となる。さらに、温度による影響によって液晶の特性が変化する。 【解決手段】本発明における液晶素子はそれぞれ独立に駆動可能電極を設け、最初に各電極全てに電圧を印加し、その後一本づつｏｆｆにする。すなわち、電極１本１本に加わるＯＮ−ＯＦＦの電圧印加のステップ幅は大である。光照射領域に複数の電極を有する旋光用液晶素子２６に加わる全電極に対する印加電圧を調節した後、各電極１本１本に加わる印加電圧をＯＮ−ＯＦＦする。 【選択図】 図１

光変調装置

【課題】旋光性物質を液晶を用いて測定する場合、旋光方向が判明していない物質については測定できない可能性がある。また、旋光性の異なる物質が混在している場合は波長の異なる光源を用いて各々の物質に対する比旋光度を利用して各々の濃度を測定できることが開示されているが、各々の物質の濃度によっては左右両方向の旋光度の測定となるので測定困難となる。 【解決手段】両旋光度を測定可能にするため、右旋光測定用の液晶領域と左旋光測定用の液晶領域を設ける液晶素子を用いる。本発明の光変調装置により、旋光測定用液晶素子を取り替えることなしに、小型で低消費電力でゴミなどの心配のない、右旋光測定および左旋光測定が可能な濃度測定装置の作製が可能となる。 【選択図】 図１

便座

【課題】従来は、尿成分の測定において、試薬や標準液や緩衝液等の消耗品があり、メンテナンスが煩わしく、ランニングコストが高いという問題がある。また、メンテナンスフリーの光学測定方式を用いた場合、測定対象の尿糖等は微量であるため、非常に高い測定精度が必要であり、温度変化により、測定精度が低下するという問題がある。 【解決手段】尿成分を測定するための測定光学ユニットと、採尿ユニットと、演算・表示ユニットを有し、前記測定光学ユニット、及び前記採尿ユニットが、温調機能により体温近傍に温調され、尿成分測定時のみ、前記採尿ユニットが突出することを特徴とする便座である。 【選択図】 図１

光変調装置

【課題】光変調素子としての液晶素子の分解能を向上させるために、独立に駆動可能電極を設け、電極１本１本に加わるＯＮ−ＯＦＦの電圧を印加することが考えられる。しかしながら、実際の装置においてはさらなる分解能を必要とする。例えば、尿糖測定や非侵襲の血糖値計を想定した場合、検出分解能としては１００ｍｇ／ｄｌ以上の分解能が要求される。 【解決手段】この方式において分解能をあげるためには光照射領域内の電極の数を多くすることである。本発明の液晶素子の電極を１方向からだけではなく、多方向から光照射領域に配線することによって、光照射領域内の電極の数を多くする構造とする。第１の有効電極１５以外に第２の有効電極１６および第３の有効電極１７を設ける。上記構造を採用することにより、光照射領域１３内の電極数が増え、光変調装置である液晶素子３３の分解能が向上する。 【選択図】 図１

濃度測定装置

【課題】 試料の旋光度を測定する事により試料内の旋光性物質の濃度を測定する際、特に尿中におけるグルコース濃度を測定する際、尿中に含まれる様々な測定阻害成分を樹脂類を用いて除去するときに、尿を樹脂に通液しただけではグルコースが樹脂間に物理的に挟まってしまうなどの原因により、グルコースを高い割合で回収するのが困難となる。 【解決手段】 尿を樹脂を充填したカラムに通液した後に、純水などの洗浄水を更に同一のカラムに通液することによって、尿の通液時に回収されなかったグルコースを回収することができる。この時、通液後のサンプルには測定阻害成分はほとんど含まれていないため、通液後のサンプルの旋光度を測定する事で、元の尿中におけるグルコース濃度が測定阻害成分の影響なしに高精度に測定できる。 【選択図】 図１

発光モジュール

【課題】 基板上にライン状に配列される複数のＬＥＤ列を複数の給電電極によって選択的に発光制御することができると共に、全体的な発光バランスを保った状態で段階的に明るさを調整することのできる発光モジュールを提供することである。 【解決手段】 基板１２上に複数並列して配置され、各列が複数個のＬＥＤ１３の縦列集合体からなるＬＥＤ列（Ｌｎ１，Ｌｎ２）、（Ｍｎ１，Ｍｎ２）、（Ｎｎ１，Ｎｎ２）と、複数の給電電極１４と、複数の折り返し電極１５とを備える発光モジュール１１であって、前記ＬＥＤ列は、一の給電電極から一の折り返し電極に向けて電気的に接続される往路列と、一の折り返し電極から一の給電電極以外の他の給電電極の一つに向けて電気的に接続される復路列とで構成され、前記複数の給電電極のうち、所定の一対の給電電極間に電源電圧を印加することによって、所定の往路列及び復路列からなるＬＥＤ列を発光させるように構成した。 【選択図】 図１

濃度測定装置

【課題】旋光性物質を液晶を用いて測定する場合、旋光方向が判明していない物質については測定できない可能性がある。また、旋光性の異なる物質が混在している場合は波長の異なる光源を用いて各々の物質に対する比旋光度を利用して各々の濃度を測定できることが開示されているが、各々の物質の濃度によっては左右両方向の旋光度の測定となるので測定不可能となる。 【解決手段】上記課題の両旋光度を測定可能にするため、旋光角度変調手段９３として右旋光用液晶素子８と左旋光用液晶素子９を設けることとする。さらに、これらの液晶素子を光源の波長によって使い分けることによって旋光性の異なる物質が混在している検体の濃度を測定できる。 【選択図】　　　図１

濃度測定装置

【課題】試料の旋光度を測定することにより試料内の旋光性物質の濃度を測定する濃度測定に於いて、試料中の所望の旋光性物質以外の旋光性物質を除去するのに、イオン交換樹脂や合成吸着剤、活性炭等を充填剤としたフィルターによる除去は有用である。特に、生体試料を測定する場合は、衛生・感染面から、フィルターは測定ごとに取り替え、使い捨てタイプにするのが望ましい。しかし、使い捨てタイプのものにした場合、測定ごとにフィルターを取り替える作業が必要であったり、フィルターを脱着する機構が必要であった。 【解決手段】試料の旋光度値から試料濃度を測定する濃度測定装置に、フィルターの内容物を充填するフィルター内容物導入手段を設ける。ユーザーは測定ごとにフィルターを取り替える手間が省ける上に、フィルターの容器は繰り返し使用できるため、環境への負荷が少ない製品を提供することが可能となる。 【選択図】図１

濃度測定装置

【課題】 試料の旋光度を測定する事により試料内の旋光性物質の濃度を測定する濃度測定に於いて、試料中の所望の旋光性物質以外の旋光性物質を除去するのに、イオン交換樹脂や合成吸着剤、活性炭等を充填剤としたフィルターによる除去は有用である。ただし、試料中に想定以上の阻害成分が含まれていると、準備しておいたフィルターでは除去しきれず測定が不能になってしまう。 【解決手段】 測定対象物質がフィルターを通って、流出するのにかかる時間とその割合を予め調べておき、マイクロコンピューター等の記憶手段に記憶させる。時間経過に伴う測定対象物質流出率を利用した旋光度予測機能を付加することで測定不能を回避することができる。 【選択図】 図１

濃度測定装置

【課題】樹脂による方法では充分に洗浄が行えず、別途防腐剤・洗浄剤・試薬を常に装置内に保持しておくのはスペースやメンテナンス上は好ましくない。特に光測定における測定試料を保持する容器に関しては、汚れによる光の透過率変化や旋光物質の付着などによる測定精度の低下を招く。 【解決手段】樹脂を備えた容器１３と測定セル８を備えたカセット３０を装着することにより、測定試料は容器１３を通り抜けて尿中グルコース以外の旋光成分を除去して測定セル８に至る。この時、光学測定装置９が測定セル８に光を透過させて旋光度を測ることによって尿中グルコース濃度を求める。測定後、カセット３０ごと廃棄し、次回の測定のために新規のカセット３０を装着する。 【選択図】図１

濃度測定装置

【課題】尿中の旋光性成分の濃度を旋光度を用いて測定する際、樹脂を用いて尿中の測定阻害成分を除去する手法においては、樹脂の交換容量に限りがあるため、一定量以上の測定阻害成分は除去できなくなってしまう。そこで、樹脂量を少ない状態に保ったまま除去する場合、尿を希釈する方法が考えられるが、希釈倍率が低いと測定阻害成分が除去できない可能性があり、逆に倍率が高すぎると希釈倍率に反比例して測定精度が低下してしまう。 【解決手段】尿の透過率と測定阻害成分の相関を用いて尿の透過率より尿中の測定阻害成分の大まかな量を推測し、その量に最適な希釈倍率において尿を希釈することにより、測定阻害成分の除去が完全にでき、かつ、過剰に希釈しすぎて測定精度を低下させることもないため、高精度にグルコース濃度を測定することができる。 【選択図】図１

濃度測定装置

【課題】樹脂による方法では広い範囲の阻害成分を除去しようと考えた場合、人それぞれの状態を考慮して、明らかに所定の阻害成分が無い場合でも、その阻害成分除去のための樹脂を常に備えていなければならない。このことは無駄な使用量を増加させるだけでなく、廃棄物を増やすことにより環境上も好ましくない。 【解決手段】本発明では図１に示すとおり、容器脱着口６７に複数の樹脂フィルターを有する常用前処理用容器を備えると共に、複数の樹脂フィルター有する予備前処理用容器を備え、ユーザースイッチ１６により常用前処理用容器のみを通液する常用パスと、予備前処理用容器１３を通過した後、常用前処理用容器８を通液する予備パスを選択する。上記により、ユーザー個々の状態によって予備前処理用容器の使用・不使用の決定ができるので、樹脂の節約ができる。 【選択図】図２

濃度測定装置

【課題】 試料の旋光度を測定する事により試料内の旋光性物質の濃度を測定する濃度測定に於いて、試料中の測定阻害成分をフィルターで除去した後、フィルターから出てくる試料の旋光度を連続的に旋光度を監視することは定常状態を検知できるため有用である。しかし、定常状態になったとはいえ、流れ続けている試料を測定するのでその値は変動しやすい。 【解決手段】 旋光度が定常状態になったことを検知した場合、送液を一定時間停止させ、停止状態の試料を改めて旋光度測定する。その結果、高精度な尿糖濃度測定が可能となる。 【選択図】 図１

Light-emitting device

A light-emitting device (10) includes a plurality of light-emitting areas (10a, 10b and 10c), and each of the light-emitting areas (10a, 10b and 10c) includes a first light-emitting block (3) and a second light-emitting block (4). Each respective first light-emitting blocks (3) include a plurality of first light-emitting elements (A1, A2, or A3), which are connected in series, and each respective second light-emitting blocks (4) include a plurality of second light-emitting elements (B1, B2, or B3), which are connected in series. The number of first light-emitting elements in each respective first light-emitting blocks (3) is the same with one another of the first light-emitting blocks (3), and the number of second light-emitting elements in each respective second light-emitting blocks (4) is the same with one another of the second light-emitting blocks (4).

タッチパネル

【課題】Ｘ−Ｙ方式の静電容量式タッチパネルにおいて、絶縁性が高く製造方法が容易な配線電極で、同じ列に配置されているX側検出電極同士、同じ行に配置されているY側検出電極同士を接続する。 【解決手段】配線電極は第１面に設けた第1面配線電極（１４、１５）と第２面に配置された第２面配線電極（１１、１２、１７、１８、１９、２０）とを有し、第１面配線電極と第２面配線電極、または第２面配線電極と検出電極（２３、２４）とは接続部で電気的に接続され、接続部には前記第１面と前記第２面とを貫通するコンタクトホールを設けたことを特徴とする。 【選択図】図２

液晶表示装置およびその集積回路

(57)【要約】 【課題】 ＣＯＧ型液晶駆動集積回路では液晶駆動集積 回路の短辺に多くの信号端子と電源端子を備えているた め入力電極と電源電極の引き回しが複雑で細くなる。こ のため横だし液晶駆動集積回路を複数使う場合、接続抵 抗と圧着強度を補うための広いＦＰＣ圧着スペースが必 要となる。 【解決手段】 液晶駆動集積回路の入力電極を図１のご とく導電線で結ぶ方法で接続して抵抗を低くすると共に 額縁幅を小さくする。

濃度測定装置

【課題】 尿中のグルコース濃度を測定する手法として旋光性を用いた場合に、グルコース以外の旋光性物質が阻害物質となる。阻害物質の一つとしてはアスコルビン酸が挙げられ、これは尿中に大量に含まれる可能性があるため、グルコースの旋光度が測定できない、もしくは測定誤差が発生するといった状況が考えられる。 【解決手段】 試料に直線偏光を照射し、試料の旋光度を測定することにより試料中の旋光性物質の濃度を測定する濃度測定装置において、旋光度を測定する手段の他に試料中のアスコルビン酸濃度を測定する手段を付加することによって、グルコース濃度測定の際の阻害物質であるアスコルビン酸による旋光度を算出し、測定した旋光度からアスコルビン酸による旋光度を減算することによって、アスコルビン酸の影響を除去することができるため、高精度のグルコース濃度測定が可能となる。 【選択図】 図１

カセット

【課題】阻害成分除去のための樹脂は高温に対して弱く、保存や搬送時の温度や湿度等の外部環境の影響により吸着機能を低下させる。 【解決手段】外壁部２８とフィルター壁部３０の間にフィルター壁部３０の四方を取り囲んで洗浄液槽３２が形成されており、洗浄液槽３２には洗浄液が満たされている。従って、洗浄液が所定の厚みで樹脂を取り囲む構造になっているので、外気温に対して樹脂が影響を受けにくく、温度等外部環境に弱い樹脂は守られる構造となる。さらに、構造を工夫することによってカセット上面も洗浄液にて保護することも可能である。 【選択図】図３

濃度測定装置および便器

【課題】 尿成分の測定を行う際、例えば酵素法を用いた手法では、一定期間または一定時間毎に酵素センサーを取り替える必要があり、また緩衝液などの消耗品を補填するなど、被験者に対してのメンテナンスの負荷が大きい。また、その他の光学的な手法を用いた場合においても汚れが付着するのは明白で、掃除などのメンテナンスが必要となる。 【解決手段】 便器に備え付けの濃度測定装置に尿中の測定阻害成分を除去するフィルタをセットするフィルタセット部を配置し、被験者は測定前にフィルタをセットし、測定時に測定開始ボタンを押して排尿をするという簡単な動作のみで、尿の採取、フィルタの搬送、尿の送液、尿中成分の濃度測定、測定値表示、装置の洗浄、フィルタの廃棄が自動的に行われ、被験者に対するメンテナンスの負荷が小さい上で、尿成分濃度の測定をすることが可能となる。 【選択図】 図１

濃度測定装置

【課題】 旋光性を利用した尿中のグルコース濃度測定に於いて、グルコース以外の旋光性成分であるアミノ酸、アスコルビン酸等は阻害物質であり、除去が必要である。そこでイオン交換樹脂を用いた除去方法が考えられる。しかし、除去対象とする物質の濃度変動や予想し得ない物質等の影響によって突発的な樹脂の汚染が起こる可能性がある。樹脂の汚染によって除去が正常に行われないと、濃度測定に異常をきたす。 【解決手段】イオン交換樹脂の飽和状態を検知する手段を設けることで、濃度測定異常を検知し、より高精度な濃度測定を維持する。 【選択図】 図１
