Optical information recording medium

An optical information recording medium having a structure in which irregular reflection of information light and recording/reproducing light from the reflective layer of an optical information record medium is prevented, thereby reducing the noise appearing on the reproduced image. The optical information recording medium for recording information by holography comprises a transparent substrate, a recording layer where information is recorded by an interference pattern, and a filter layer formed between the transparent substrate and the recording layer and adapted to transmit a light of a first wavelength and reflect a light of a second wavelength. The filter layer of the thus structured optical information recording medium transmits a light of the first wavelength (for example, red light) and reflects a light of the second wavelength (for example, green light). As a result, two lights of different wavelengths can be separated and used for different purposes without being influenced by each other.

Clutch and engine

Die erfindungsgemäße Kupplung hat ein ringartiges Kupplungsgehäuse, einen drehend angetriebenen Drehkörper der Antriebsseite, einen Drehkörper der angetriebenen Seite, einen Rollkörper und ein Stützelement. Die Kupplung ist so aufgebaut, dass, wenn der Drehkörper der Antriebsseite beim Antreiben mit der Drehung beginnt, der Drehkörper der Antriebsseite mit dem Stützelement in einer Drehrichtung in Kontakt gelangt und den Rollkörper in der Drehrichtung durch das Stützelement drückt, wodurch der Rollkörper vor einem Ergreifen freigegeben wird, das durch das Kupplungsgehäuse und den Drehkörper der angetriebenen Seite bewirkt wird. Das Stützelement hat einen Lasterzeugungsabschnitt zum Erzeugen einer Last, die es dem Stützelement erschwert, sich um die Drehachse des Drehkörpers der Antriebsseite zu drehen, wenn zumindest der Drehkörper der Antriebsseite beim Antreiben mit dem Drehen beginnt. The clutch according to the invention has a ring-like clutch housing, a drive side rotatably driven rotary body, a driven side rotating body, a rolling body and a support member. The clutch is constructed such that, when the drive-side rotary body starts to rotate upon driving, the drive-side rotary body contacts the support member in a rotational direction and pushes the rolling body in the rotational direction through the support member, thereby preventing the rolling body from seizing is released, which is effected by the clutch housing and the rotary body of the driven side. The support member has a load generating portion for generating a load that makes it difficult for the support member to rotate about the rotation axis of the drive-side rotating body when at least the drive-side rotating body starts turning when driven.
