Title: Method for manufacturing grooved clutch plate and device for using same
Inventor: FUJIWARA KIROKU
IPC: B21H8/00
Filed: 1986-09-27
Abstract: PURPOSE:To form a good shaped tapered groove on a strip steel, to reduce the noise of a clutch plate and to improve an oiling by rolling a steel strip with a roll having an annular projection and performing a progress following up rolling by the roll with annular projection in the perpendicular direction. CONSTITUTION:A strip steel plate 2 is rolled by the roll 1 with plural annular projections 10. The strip steel plate 2 is then rolled at a right angle 33a in the progressing direction by the roll 3 with plural annular projections 30 rolling along the guide part 32 synchronously transferring with the progressing direction of the strip steel plate 2. It is thereafter rolled in a smooth surface by a finishing roll 4. The cross groove 24 impressed on the strip steel plate 2 becomes in a good deep groove taper shape. In case, therefore, this strip steel plate 2 is punched and formed in a clutch plate, the noise generation at the time of using a clutch is reduced and an oil cut is eliminated with the oil flow onto the surface becoming smooth.

Abstract: PURPOSE:To obtain a satisfactory color-forming sensitivity and a suitability for a high-speed recording and to inhibit sublimating properties to the utmost by incorporating a 4,4'-bisalkoxy biphenyl compound having a specific melting point as a color-forming accelerator. CONSTITUTION:In thermal recording paper mainly composed of a leuco dye and an organic acid reacting with the leuco dye to produce a color, 4,4'- bisalkoxy biphenyl compound shown by a formula (where R represents 3-6 C alkyl group having at least one secondary carbon atom or tertiary carbon atom) is contained as a color-forming accelerator. The 4,4'-bisalkoxy biphenyl compound can be easily obtained by dehydrating corresponding alcohol and 4,4'-biphenol or by an ether synthesizing method in which a corresponding halide, such as chloride and bromide, is caused to react with the sodium salt or potassium salt of the 4,4'-biphenol. The aforesaid 4,4'-bisalkoxy biphenyl compound has a melting point ranging 60-180 deg.C, therefore having slow sublimating properties and a color-forming accelerating effect superior to such a material as fatty acid amide.
