摘要:
A polyimide film favorably employable in a method of producing a through-hole in an aromatic-polyimide film having on its surface a laminated or deposited metal film by applying laser beam onto the polyimide film, preferably is composed of a high Tg aromatic polyimide layer which has a Tg of 300° C. or higher or has no noticeable Tg and is produced from a biphenyltetracarboxylic acid compound and an aromatic diamine compound and a low Tg aromatic polyimide layer which has a Tg of lower than 375° C. but higher than 200° C., provided that the Tg of the low Tg polyimide layer is lower than the Tg of the high Tg polyimide layer and the metal film is laminated or deposited on the surface of the low Tg polyimide layer on the side not facing the high Tg polyimide layer.

An aromatic polyimide laminate composed of an aromatic polyimide composite film, a metal film, and a release film is disclosed. The aromatic polyimide composite film is composed of an aromatic polyimide substrate film and two thermoplastic aromatic polyimide layers. Each thermoplastic layer is fixed to each surface of the substrate film. The substrate film has no glass transition temperature of lower than 350° C., and the thermoplastic aromatic polyimide layer has a glass transition temperature of 190-280° C. The metal film is fixed, with no intervening adhesive layer, to one thermoplastic aromatic polyimide layer at a 90° peel strength of 0.8 kg/cm or more and the release film is fixed, with no intervening adhesive layer, to another thermoplastic aromatic polyimide layer at a 90° peel strength of 0.001-0.5 kg/cm, under such condition that the latter peel strength is one half or less of the former peel strength.

A roll of a web composed of an aromatic polyimide composite film and a metal film in which the polyimide composite film is composed of a non-thermoplastic aromatic polyimide base film and a thermoplastic aromatic polyimide cover film, the polyimide composite film showing a heat shrinkage ratio of less than 0.1% at 300° C., can be produced by heating a corresponding roll of web composed of a metal film and an aromatic polyimide composite film having a heat shrinkage ratio of more than 0.1% at 300° C., at a temperature between 150° C. and a glass transition temperature of the thermoplastic aromatic polyimide cover film, for a period of at least one minute.
摘要:
An input device includes a pressure-sensitive or capacitive planar input unit with an indicator sheet which has input sections being secured to the surface of the planar input unit. A tactile feedback generator is provided at the back side of the planar input unit. The tactile feedback generator includes dome-shaped inversion plates that are separately provided at locations corresponding to the input sections and provide feedback to the operator. When an input section is pressed, an operation signal in accordance with what is indicated at the pressed input section is generated.
摘要:
An adjusting mechanism (56) is provided to produce an anti-overturning moment to reduce an overturning moment acting on an orbiting scroll (26) during its revolution in a revolving-angle area in which the overturning moment becomes a certain value or more. Accordingly, revolution movement of the orbiting scroll (26) can be made stable by changing a pressing force of the orbiting scroll (26) against the fixed scroll (22) according to fluctuation of the overturning moment due to the revolution of the orbiting scroll (26), thereby improving the compression efficiency of a scroll-type compressor (1).

In a scroll type compressor (1) that includes a fixed scroll (21) fixed inside of a casing (10) and a movable scroll (22) meshed with the fixed scroll (21) and presses the movable scroll (22) against the fixed scroll (21), the pressing force of the movable scroll (22) against the fixed scroll (21) is obtained from the pressure of a high-pressure space (S2) that acts on the back face of the movable scroll (22) and the pressing force is controlled in accordance with the variation in the compression ratio with the change in the operating condition thereby preventing decrease in efficiency and mechanical loss.

The disclosed air belt can protect a vehicle occupant in the event of an emergency. The disclosed air belt may include a folded back body formed by folding back a bag-shaped belt into a belt like shape and an extendable cover covering the folded back body. An inner surface of the cover can be bonded to an outer surface of the folded back body with a bonding agent. The bonding agent can be bonded in a scattered point-like manner.
