Ceramics for Decorative Component and Decorative Component Using the Same

Номер: US20120115706A1
Автор: Mizuho Ohta
Принадлежит: Kyocera Corp

An object of the present invention is to provide ceramics for decorative component which have golden color tone and provide high-grade impression, aesthetic satisfaction and mind soothing effect, and also has small color difference and does not cause deterioration in beautiful appearance of the decorative surface, and a decorative component using the same. The ceramics for decorative component comprise a titanium nitride-based sintered body containing nickel, niobium, chromium and carbon, and are characterized in that a content of carbon on a decorative surface is not less than 0.4% by mass and not more than 0.9% by mass, and the decorative surface does not substantially contain aluminum. Since the decorative surface does not substantially contain aluminum, a preferable golden color can be provided, and an adhesion of silver-white spot-like foreign matters on the decorative surface is less likely to occur as a result of bonding of aluminum to the above metal component. Therefore, deterioration in beautiful appearance of the decorative surface is less likely to occur.

A nonmagnetic stainless steel which has a higher electrical resistivity than existing nonmagnetic alloys, a production process for producing the stainless steel, and a radio wave receiver. The receiver has a main case and rear cover constituted of a nonmagnetic stainless steel having an electrical resistivity as high as more than 100 μΩ·cm and consisting of C: not more than 0.1%, Si: 4.0-7.5%, Mn: not more than 2.0%, Ni: 25.5-30.0%, Cr: 15.0-20.0%, Mo: 0.1-3.0%, Cu: 0-2.0%, in mass % and the balance Fe and impurities. Even if some variable magnetic flux generated by a coil of an antenna runs through the main case and the rear cover, the receiving efficiency of the antenna can be prevented from being reduced by eddy current loss and a sufficient radio receiving sensitivity can be obtained. This nonmagnetic stainless steel is produced by hot and/or cold plastic working and subsequent solution treating conducted at 1,000-1,180° C.

Принадлежит: ASSOCIATION SUISSE POUR LA RECHERCHE HORLOGERE

The present invention describes the use of amine molecules (N) and phosphonic compounds (P) for coating surfaces intended to be used in the field of horology. Since these two types of compounds are alkaline and acid in nature, they form pairs of ions that interact with all types of surfaces, whether these are composed of mineral materials such as glass, metal, non-oxidised materials (inter alia gold, rhodium and their alloys), or also polymeric materials. Taking advantage of the surprising complementary nature of these two types of compounds, the present inventors propose a composition and a coating process that enable functionalisation layers to be formed on any type of material, in particular those used in clock mechanisms. 118-. (canceled)19. A process for coating a surface in a clock mechanism or a device integrated into a watch product with a molecular functionalization layer , the process comprising:a) optionally preparing said surface by washing in a solvent and/or in an aqueous detergent, then drying,b) contacting said surface with a first composition comprising an effective quantity of a phosphonic compound until self-assembly of said phosphonic compound to a fine layer on said surface,c) contacting said surface with a second composition comprising an effective quantity of an amine compound until self-assembly of said amine compound to a fine layer on said surface to form a functionalized surface,d) removing supernatant from the functionalized surface,e) rinsing the functionalized surface, andf) drying the functionalized surface;wherein said phosphonic compound and said amine compound are different compounds.20.

A decorative article has a substrate of which at least part of the surface is configured with Ti or stainless steel; and a coating made of primarily TiC and disposed on the substrate. The coating has at least a first region, and a second region disposed closer to the substrate than the first region. The elastic modulus of the second region is greater than the elastic modulus of the first region. 1. A decorative article comprising:a substrate of which at least part of the surface is configured with Ti or stainless steel; and 'an elastic modulus of the second region being greater than the elastic modulus of the first region.', 'the coating having at least a first region, and a second region disposed closer to the substrate than the first region,'}, 'a coating made of primarily TiC and disposed on the substrate,'}2. The decorative article described in claim 1 , wherein:the C content of the first region is greater than or equal to 45 wt % and less than or equal to 60 wt %.3. The decorative article described in claim 1 , wherein:the C content of the second region is greater than or equal to 35 wt % and less than or equal to 55 wt %.4. The decorative article described in claim 1 , wherein:{'sub': 1', '2', '1', '2, 'if the C content of the first region is X(wt %), and the C content of the second region is X(wt %), 5<=X−X<=25.'}5.

Protective device () for the protection of a structural component, notably a main plate (), of a timepiece movement () on a receiving surface comprised in this structural component () for receiving in abutment a complementary bearing surface () of a wheel set (). 1. A protective insert for the protection of a housing forming a surface of revolution generated by a given profile in a structural component of a timepiece having a given surface hardness , said insert including at least one slide surface having a higher surface hardness than said given surface hardness , said insert including at least one machined portion of revolution about an axis of revolution whose profile is complementary to said given profile , wherein said insert includes at least one complementary , first , flat indexing surface perpendicular to said axis of revolution , and at least one complementary , second , flat indexing surface parallel to said axis of revolution , and in that at least said complementary first indexing surface forms a said slide surface having a higher surface hardness than said given surface hardness.2. A structural component of a timepiece movement having a given surface hardness claim 1 , and including at least one housing forming a surface of revolution generated by a given profile claim 1 , said structural component including a protective device arranged to receive in abutment a complementary bearing surface of a wheel set of said movement on a theoretical receiving plane claim 1 , wherein said protective device includes at least one insert according to claim 1 , assembled on or in said structural component in a said housing so that said flat claim 1 , slide surface thereof coincides with said theoretical receiving plane claim 1 , and wherein said structural component includes a rotation stop surface arranged to cooperate with a complementary rotation stop surface comprised in said insert claim 1 , said insert is fixedly held in relation to said structural component ...
