IPC: C09D167/08
Filed: 1986-10-01
Abstract: PURPOSE:To prevent sagging, cissing, etc. of a paint film without detriment to its gloss, water resistance, etc., by using hydrogenated castor oil or its fatty acid as part of an oil or its fatty acid as a constituent of an oil-modified alkyd resin. CONSTITUTION:0.5-5wt% hydrogenated castor oil or its fatty acid is incorporated in an oil (e.g., linseed oil or safflower oil) or its fatty acid as part of materials for producing an oil-modified alkyd resin of an oil length of 35-70%. The obtained oil or fatty acid component is reacted by heating with a polyalcohol component (e.g., pentaerythritol) and a polybasic acid component (e.g., phthalic anhydride) to produce an oil or fatty acid-modified alkyd resin of an oil length of 35-70% for room temperature-drying paints. A paint obtained by mixing this resin with an organic solvent, a pigment, additives, etc., is freed of sagging, cissing, etc., and is good in the edge covering property, levelling property, etc., of a paint film.

Abstract: PURPOSE:To suppress the generation of a heat crack owing to a thermal-shock by a method wherein the corner part of the tip of a disc brake rotor is formed in a curved shape and surface coarseness is set to a specified value or less. CONSTITUTION:Three kinds of disc brake rotors, such as all four corners are formed in a curved shape, two corners on the outer side are formed in a curved shape, two corners on the inner side are processed in a C-shape, and all four corners are processed in a C-shape, wherein the shapes of the corner part of the tip of an outer slide surface 2 and the corner part of the tip of an inner slide surface 3 are different from each other are manufactured to execute a heat crack generation test. As a result, the disc brake rotor wherein the corners of the tip are all formed in a curved shape has the number of the heat cracks which is less than that of a compared good. This constitution relaxes concentration of a stress owing to a thermal shock in a way that the corner part of the tip is formed in an R-shape. Further, as a result of a thermal-shock test regarding coarseness of the corner part of the tip being executed, a smooth surface (2.5S or less) has the number of the heat tracks being less than that of a coarse surface and the more surface coarseness is higher, the more the frequency of the generation of the heat track is remarkably further often.

Title: Circuit breaker
Inventor: KATO KAZUHIKO
IPC: H01H71/12
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a circuit breaker wherein dispersion in breaking performance is small and reliability is high. SOLUTION: A link pin 20 of a make/break mechanism part 4 is adapted to serve as a stopper for suppressing an overstroke of a movable contact block 9 in an ON to OFF action and a tripping action. The movable contact block 9 makes turning motion centering around a pin in such an event that an excessive current flows. In that event, turning motion beyond a predetermined angle is prevented by an end 9a of the movable contact block 9 hitting against the link pin 20. Accordingly, a breaking distance being kept constant, therefore dispersion in breaking performance aspects of every individual product being excluded, breaking performance can be stabilized. Since stress exerted to parts can be reduced, long life and high reliability can be expected.

Title: Magnetic recording medium
Inventor: MATSUMOTO TOKIRO
IPC: G11B5/66
Filed: 1984-11-07
Abstract: PURPOSE:To obtain a magnetic recording medium having superior electromagnetic transducing characteristics, lubricity and durability by forming the protective layer consisting of a perfluoroethylene-alkylene oxide copolymer and a specified polymer on a magnetic layer. CONSTITUTION:A magnetic layer is formed on a nonmagnetic support by a thin film deposition method, and a protective layer consisting of a perfluoroethylene-alkylene oxide copolymer and a polymer represented by formula I (where n is 0, 1 or 2, and m is a positive number) is formed on the magnetic layer. Since the protective layer has the adsorption effect of the alkylene oxide on a metallic surface and the protecting and lubricating actions of a perfluoroethylene polymer and the polymer represented by formula I, the layer is very effective in improving the wear resistance and traveling performance of the resulting thin film type magnetic recording medium. In case of n=3 or 4, the number of Cl atoms is increased, and the number of F atoms is relatively reduced, so the magnetic layer is liable to take sliding scratches during contact with a magnetic head.

Abstract: PURPOSE:To prevent a wire material grid from loosening by preparatorily bending a frame which bends by the shrinkage force of the grid wire, and generating reaction force to the shrinkage force with the restoring force of the bent grid in attaching the grid to a frame of a color cathode tube. CONSTITUTION:A wire material grid 4 is aligned on a top face 3 of a main beam 1 by means of an aligning plate 5 at a constant pitch. A weight 11 is suspended from the grid 4 through a pulley 10. Then, the main beam 1 is transformed by clasping a plunge bolt 18 of a support table 17. This transformation amount delta is set to be equal to a bend amount of the center part of the main beam 1 occurring in the cooling process of the wire material grid 4 after heating. Then, the grid is heated by hot air by means of a heater 23. The temperature of the hot air is arranged to get gradually higher at both ends than the center. A welding current is applied by means of an electrode rod 7 to fix the grid to a frame and cool it. The push bolt 18 is loosened. Thus, tension can be produced in the wire material grid 4 due to shrinkage force.
