摘要:
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.

In a light irradiation device in which a light emitting element is attached to a printed circuit board, the heat radiation properties are enhanced, and improvement of the light emitting efficiency and reduction of the size and weight are realized. A Cu pattern covered with Ni is formed on a metal substrate 11. Light emitting elements 11 are mounted on the pattern in the form of a series circuit. Metal substrates in each of which the series connection is formed are connected to one another in parallel. Since Ni has excellent corrosion resistance and a high reflection efficiency, the surfaces of the substrates themselves can be used as reflective plates. A lens 37 is formed for each of the light emitting elements, whereby the emission efficiency can be further improved. Flow-stopping means 36 made of a brazing material is formed around each of the light emitting diodes 10. Also the surface of the brazing material is used as a reflecting surface.

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 position closest to the mounting position of a microcomputer in a casing of a hybrid integrated circuit device on which is mounted the microcomputer and its peripheral circuit elements, an insertion hole is formed for a non-volatile memory which feeds data to the microcomputer. A socket for connecting the non-volatile memory is provided at the bottom of this insertion hole. Because of this configuration it is possible to connect the microcomputer and the non-volatile memory at an extremely short distance and the mounting efficiency of the integrated circuit device is increased. In addition, the non-volatile memory can detachably be mounted. Furthermore, the external shape of the insertion hole for the non-volatile memory is essentially the same as the external shape of the non-volatile memory so that when the non-volatile memory is inserted, the entire surface of this hybrid integrated circuit device is almost flat, providing excellent handling characteristics.

The inventive method for forming a cured film on a substrate surface comprises coating the surface with a room temperature curable organosiloxazane polymer comprising, in a molecule, (a) at least one organosiloxane unit represented by the unit formula (a) at least one organosiloxane unit represented by the unit formulaR.sup.1.sub.a SiO.sub.(4-a)/2,and (b) at least one organosilazane unit represented by the unit formulaR.sup.2.sub.b Si(NR.sup.3).sub.(4-b)/2,in which R.sup.1, R.sup.2 and R.sup.3 are each a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group, not all of them being simultaneously hydrogen atoms, and the subscripts a and b are each a positive integer of 1, 2 or 3 with the proviso that a and b cannot be simultaneously equal to 3, in a molecule and subjecting the coating film to exposure to a moisture-containing atmosphere. The method is useful for forming a surface-protecting film or for imparting surface releasability.

In a light irradiation device in which a light emitting element is attached to a printed circuit board, the heat radiation properties are enhanced, and improvement of the light emitting efficiency, reduction of the size and weight, and prevention of temporal changes are realized. A Cu pattern covered with Ni is formed on a metal substrate 11. Light emitting elements 11 are mounted on the pattern in the form of a series circuit. Metal substrates in each of which the series connection is formed are connected to one another in parallel. Since Ni has excellent corrosion resistance and a high reflection efficiency, the surfaces of the substrates themselves can be used as reflective plates. A lens 37 is formed for each of the light emitting elements, whereby the emission efficiency can be further improved. A transparent substrate 50 is bonded via a seal 51, and temporal changes of a light emitting element 10 and electrodes which are sealed therein are suppressed.

When a circuit is configured in one region of a hybrid integrated circuit substrate, a position recognition mark 53 and a flow stop 57 are disposed in the open region. Also the region is covered with Ni so as to function as reflecting means.
