  • Patent number: 9068597
    Abstract: There is provided a sliding member including: a substrate; and a protective film provided on the substrate, wherein the protective film is composed only of a metal base layer provided on the substrate, a low-hardness diamond-like carbon layer provided as a single layer on the metal base layer, and a high-hardness diamond-like carbon layer provided as a single layer directly on the low-hardness diamond-like carbon layer. The sliding member has the protective film which has excellent frictional wear resistance property and satisfactory adhesion property to the substrate, regardless of having a simple structure.

  • Patent number: 8377211
    Abstract: Disclosed is a device for vacuum processing that performs vapor-deposition on a substrate being heated in a vacuum chamber; the device, wherein the chamber has a light transmissible window formed in a section of the chamber; the light transmissible window and a holding part holding the substrate are connected by a linear space isolated from other parts in the chamber; a laser emitter is installed outside the light transmissible window; and the laser emitter emits a laser beam to the substrate through the linear space, thereby heating the substrate. This device enables laser heating, eliminating conventional drawbacks such as a decrease in laser output.

  • Patent number: 7511114
    Abstract: Colored aromatic polycarbonate resin compositions are prepared by dispersing a colorant (b) selected from phthalocyanine-based compounds, anthraquinone-based compounds and ultramarine blue in a polyalkyleneglycol compound (c) having a number-average molecular weight of 62 to 4000 of formula (2): HO—[—CHR1—CHR2—]m—OH??(2) where R1, R2, R3 and R4 are independently hydrogen atoms or alkyl groups, and m is not less than 1. The dispersion is added to an aromatic polycarbonate resin (a) kept in a molten state which has a viscosity-average molecular weight of not less than 16000 and contains a branched constitutional unit of formula (1): in an amount of 0.3 to 0.95 mol % where X is a single bond, an alkylene group having 1 to 8 carbon atoms, an alkylidene group having 2 to 8 carbon atoms, a cycloalkylene group having 5 to 15 carbon atoms, a cycloalkylidene group having 5 to 15 carbon atoms, or a divalent connecting group —O—, —S—, —CO—, —SO— and —SO2—.

  • Patent number: 6750314
    Abstract: To produce an aromatic polycarbonate excellent in physical properties and hue by a simplified step as compared with a conventional one. A process for producing an aromatic polycarbonate, which comprises the following steps (1) to (3): (1) a step of reacting phenol with acetone in the presence of an acid catalyst to convert part of the phenol into bisphenol A, to obtain a bisphenol A/phenol composition, (2) a step of supplying the bisphenol A/phenol composition held in a molten state in a liquid form to an aromatic polycarbonate production step, and (3) a step of reacting the bisphenol A and a carbonate material to produce an aromatic polycarbonate.
