Title: Coil spring and damper
Inventor: UEHARA HIROSHI
IPC: F16F15/12
Filed: 1995-03-17
Abstract: PURPOSE: To maintain parallel compression of a coil spring and reduce wear of the coil spring and its supporting member. CONSTITUTION: In a clutch disc assembly body, a separated flange 3 has a knotched section 3c of which width in the circumferential direction becomes narrow gradually from both sides in the circumferential direction from an outer peripheral side to an inner peripheral side. A second coil spring 7 consists of a wire which is extended spirally at equal intervals, and both ends 7a of the wire are extended to the inside in the direction of coil height. For this reason, free length of the second coil spring 7 becomes long gradually from the center to one side in the radial direction and becomes short gradually from the center to the opposite side on one side. Both ends 7a of the second coil spring 7 are in contact with both ends in the circumferential direction of the knotched section 3c without clearance.

Filed: 1981-04-17
Abstract: PURPOSE:To prevent backfire by providing one side of the honeycomb surface of small openings with a noncatalyst support section composed of mixture of oxide and catalyst oxide so that oxidation reaction amount may be reduced to form a low-temperature zone. CONSTITUTION:The catalyst support 1 is immersed in vinyl acetate polymer acetone solution beginning with the surface line a until the specified depth line b is reached. Then, the catalyst support 1 is made completely free of acetone by a drying oven, and the a-b section is coated with vinyl acetate polymer. Meantime, Ten percent alumina solution is diluted with water in the ratio in weight of 1:3. The resultant dilution to which pulverized zirconia is added in the ratio in weight of 10:1 is mixed with platinum chloride acid solution. Then, the catalyst support 1 is immersed in the just-mentioned solution beginning with the surface line c so that the b-c section adsorbs the solution. When the catalyst support 1 treated in this way is dried and baked, the vinyl acetate polymer is decomposed. At the same time, the alumina and zirconia stick to the mullite of the b-c section of the catalyst support 1 so that the platinum remains on the surface of the mullite or on the fine-porous surface formed of alumina and zirconia.

Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To smoothly bite the end part of a rolled material into a roll caliber and to stabilize the rolling formation by forging the tip end part at the biting side of the rolled material into the roll caliber to the width spreading direction with forging dies before biting into the roll caliber. SOLUTION: In the forging dies 4, only the tip end part at the biting side of the rolled material 3 into the roll caliber 1 is spread from the interval C between flanges of the rolled material 3 to the interval D. At the time of spreading the interval by the forging dies 4, the feeding of the rolled material 4 is stopped. The tip end part in the vertical direction of the forging dies 4 is smaller than the interval C between the flanges before spreading so as to enable come-in between both flanges of the rolled material 3, and according to separating in the vertical direction from the tip end part, this tip end part becomes the interval D after spreading the interval. By this method, the biting miss to the roll caliber is not developed and the rolling efficiency is improved.
