摘要:
In a carriage for conveying an article such as an automobile body on a coating line, a sprocket on the carriage engages an endless chain running along the path of carriage movement. The sprocket causes the article to rotate on an axis parallel to the direction of movement of the carriage. A pendulum weight is provided to cause the article normally to assume an upright condition. A lever on the sprocket shaft engages a cam as the sprocket approaches engagement with the endless chain, and causes the weight to swing in one direction. When the lever clears the cam, the weight returns by gravity, causing the sprocket to begin rotating so that it smoothly engages the chain without shock. The operation of the lever, cam and weight also impart rotation to article to be painted before the sprocket engages the chain, thereby eliminating shocks in the rotating movement of the article, which could otherwise cause sagging or running of the paint.

In a coating line conveyor for an automobile body, in which the body is movable along a path and rotated on an axis parallel to the path, the article is stopped in its erect attitude without impact force. The article is supported so that the combined center of gravity of the article and its supports is located directly below the axis of rotation of the article when the article is erect. Rotation is stopped by removing rotating power from the article supports in response to a signal generated by a sensor when the article is in its erect condition. The article then rocks back and forth under its own inertia and rapidly approaches a stable erect condition by a naturally damped oscillating motion.

A thermosetting resin composition contains (A) a mixture of an imide compound having an allyl-free maleimide group and an imide compound having an allyl-containing imide group, (B) an epoxy resin, (C) a phenolic resin, and optionally, (D) an aromatic polymer/organo-polysiloxane copolymer. Component (B) and/or (C) includes a compound containing a naphthalene ring having a double bond conjugated with an aromatic ring. The composition is easily workable and well adhesive and cures to products having improved mechanical strength, hot-water resistance, low thermal expansion, and minimized water absorption.

Disclosed is a hybrid integrated circuit device provided with an active filter. The active filter is constructed mainly from a rectifier circuit, a reactor with one terminal connected with an output terminal of the rectifier, a switching element connected with one terminal of the reactor and a smoothing condenser connected with the other terminal of the reactor. The active filter is mounted on an insulating metal substrate and has, other than the above feature, a specific circuit structure wherein the substrate is divided by a ground pattern or power supply pattern into two blocks. One block is for a large current circuit such as the rectifier circuit, the switching element, and a diode and another block for a small signal circuit such as a control circuit. The hybrid integrated circuit device is of remarkably compact size. Also, it is greatly superior in a noise performance because switching noise does not flow into the chassis of electronic equipment from the metal substrate and the control circuit is shielded from the noise produced by the large current circuit, and also because the noise caused by wiring inductance can be limited.

Fluorine-modified thermosetting reins are available as phenolic or epoxy resins having trifluoromethyl groups and a naphthalene skeleton in a molecule. They are useful as components of resin compositions or resin modifiers and cure to products having low water pickup, low coefficient of thermal expansion, and adhesion as well as heat resistance and mechanical strength. Thermosetting resin compositions having such a thermosetting resin blended therein are useful in semiconductor element packaging.

An epoxy resin composition comprising an epoxy resin, a curing agent, and a copolymer mixture comprising a long-chain organopolysiloxane copolymer [I] and a short-chain organopolysiloxane copolymer [II] which are each prepared by the addition reaction of an alkenyl-containing epoxy resin with a long-chain or short-chain organopolysiloxane containing pendant phenyl groups at a weight ratio of [II] to [I] of 0.3 to 0.6 is disclosed. The epoxy resin composition exhibits excellent printability, crack resistance, and moldability properties.

The invention provides a novel means for solving the problem of poor adhesion between the surface of a substrate of a metal or a plastic resin, e.g. polycarbonate resin, and a cured coating film of an organopolysiloxane formed thereon to impart good surface properties, e.g. hardness and weathering resistance, to the substrate surface by use of an adhesion improver as a primer which comprises a copolymer of an organosilicon compound having a hydrolyzable group and an ethylenic unsaturation in the molecule, glycidyl methacrylate and an organic monomer, e.g. methyl methacrylate and vinyl acetate, a reaction product of an aminoalkyl-containing organosilane compound and an acid anhydride and, optionally, an ultra-violet light absorber in a limited proportion.

Control of an automotive vehicle component assembling system having one or more series of assembly lines used in common for assembling various models, standards and/or specifications of vehicle component is provided by converting information and instructions relating to various models, standards and/or specifications of vehicle component into a sign. The sign is fitted onto one of the part of the component. Information and instructions from the sign are detected automatically to control picking up of parts and assembling operations in each assembly line.
