Title: Manufacture of compression-molded article
Inventor: SANNOMIYA TSUGUMI
IPC: B27N5/00
Filed: 1985-12-28
Abstract: PURPOSE:To contrive an improvement in workability, reduction in production cost and improvement in strength, by a method wherein a molding material mounted on a mold surface of a bottom force is moved by a conveying clamp and mold clamping is performed by making the material follow after the mold surface of a molding tool. CONSTITUTION:A top force 3 descends to some extent, in proportion to the descent of which a conveying clamp 4 moves in the directions C, D, a part outside of a mold of a molding mat 1 is inserted into the mold and the molding mat 1 is made into a state wherein the same is made to about follow after a mold form surface at a stage wherein mold clamping has been advanced to some extent. Although the mat 1 has begun to abut against a corner part 2a of a rising surface at this point, this is based on protrusion prevention force of the mold of the mat 1 by pressing force of the mat 1 based on the descent of the top force of the mat 1 based on the descent of the top force 3 and the clamp 4. As the mat 1 is stuck closely to a recessed part of the top force 3, even if the descent of the top force 3 advances further, it is not feared that generation of deterioration in density and breakage of the mat 1 in the corner part 2a of a protrusion of a bottom force which have been generated so far. The top force 3 descends down to the lowest position, mold clamping is completed and a compression-molded member 1b whose density is uniform and high is obtained.

Title: Method for reducing short-circuit failure rate of alkaline storage battery
Inventor: ISHIDA TOMONORI
IPC: H01M10/28
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent short-circuit failures by performing pulse discharge between positive and negative electrodes, in a state in which an electrode group consisting of the positive and negative electrodes laminated is inserted into a battery jar via a separator. SOLUTION: Pulse discharge is preferably performed at least once under a condition of 100 to 1,000 V discharge voltage, 1 to 20A discharge current, and 50 to 500 microseconds pulse width. A pulse generating circuit 1, in which a battery jar into which an electrode group is inserted as a load 2, is actuated, and pulse discharge is generated between the positive and negative electrodes. With this pulse discharge, burring or the like in contact with a opposite electrode by breaking a separator is thermally fused, and a short-circuit state is eliminated. Burring or the like which is not in contact therewith but protruded with a very narrow interval with the opposite electrode is fused thermally, a distance between both electrodes is widened, and dielectric voltage between both of these electrodes is increased. Thus, by performing pulse electric discharge, burring which causes short-circuit during actual operation is fused thermally, and becomes a conforming electrode group free of short-circuit.

Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To produce temperature gradient environment with only a heating unit, simplify the structure of a heating device, and improve heating temperature distribution by changing the spiral pitch of a spiral structure heating part to give a gradient to the surface temperature. SOLUTION: The spiral pitch of single terminal type double spiral structure is made gradually small from a terminal part 2 to the tip of a heating unit 1. Since the specific resistance of a heating member material of the heating unit 1 is constant, the surface load density is increased with decrease in spiral pitch, and the surface temperature is proportionally raised. By the temperature gradient of the heating unit 1, temperature distribution required in heat treatment is improved, load in the heating unit 1 is reduced, and efficiency is enhanced. The life is prolonged and the scale of the device is reduced.
