摘要:
The present invention provides a lock-up clutch mechanism for a torque converter, comprising a lock-up piston and a front cover having an engagement surface capable of being engaged with the lock-up piston and in which a friction material is stuck to wither one of the lock-up piston and the front cover and in which engagement and disengagement are performed in accordance with a hydraulic pressure difference between the front cover and the lock-up piston and wherein the friction material includes a first flat friction surface disposed at an outer diameter side and a second tapered friction surface disposed at an inner diameter side and further wherein, when the lock-up piston and the front cover are slip-controlled, the first friction surface is engaged with uniform face pressure, and, when the lock-up piston and the front cover are substantially integrally joined with a great hydraulic pressure difference under slip control, maximum face pressure is generated at a border between the first friction surface and the second friction surface.

Provided are a manufacturing method for a blade material and a manufacturing device for a blade material, by which a long blade material can be manufactured without using a large-sized press forging machine. A manufacturing method for a blade material, in which hot forging is sequentially performed by molds from the root side to a blade (vane) tip, wherein when a root-side portion is grasped and a material to be forged is restrained by a mold, twisting is performed on a region between the grasped portion and the restrained portion. A manufacturing method for a blade material, in which hot forging and twisting are repeated, is preferable, and a manufacturing method for a blade material, in which hot forging is performed while molds are sequentially changed, is more preferable.

A method of performing an imprint process on each of a plurality of shot regions of a substrate, wherein each shot region includes at least one of at least one valid chip area and at least one invalid chip area, the invalid chip area including an inhibited area in which resin coating is inhibited, the imprint process for a shot region including both the invalid chip area and the valid chip area includes coating the valid chip area of the shot region with the resin, bringing a pattern surface of a mold into contact with the resin, and curing the resin, and in the step of coating, at least the inhibited area of the invalid chip area is not coated with the resin.
摘要:
A process for continuously producing a thermoplastic copolymer, in which a copolymer (A) containing unsaturated carboxylic acid alkyl ester units and unsaturated carboxylic acid units is produced and in succession heat-treated to perform intramolecular cyclization reaction by dehydration and/or dealcoholization reaction, for producing a thermoplastic copolymer (B) containing glutaric anhydride units and the unsaturated carboxylic acid alkyl ester units. The obtained copolymer is excellent in heat resistance and colorless transparency and very small in foreign matter content.
