IPC: H01M10/39
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To produce a sintered material having high circularity, low warpage and excellent dimensional accuracy of the closed bottom part by firing a formed ceramic material loosely put on a columnar core material wherein the core material has an end part shape corresponding to a specific multiplication ratio of the designed shape of the inner side face of the closed bottom of the sintered material when the thermal expansion coefficient of the core material is larger than that of the sintered material. SOLUTION: The above multiplication ratio is 0.8-1.3. The core material satisfies the formula 0.8<=[R×(1+B×T)]/[S×(1+A× T)]<=1 wherein A is the thermal expansion coefficient of the core material, S is the curvature radius of the chamfered part of the end of the core material, B is the thermal expansion coefficient of the sintered material, R is the curvature radius of the inner side face of the bottom part of the sintered material corresponding to the chamfered part of the end of the core material and T is the sinterable temperature of the sintered material. The length of the core material is set to be longer than the distance from the opening of the formed material to the inside of the bottom of the cylinder. The formed material is fired from the initial stage of the firing shrinkage in a state suspended by contacting the closed bottom with the core material.

Title: Tape feeding mechanism
Inventor: MIYAGI YOSHIO
IPC: G11B15/18
Filed: 1983-12-24
Abstract: PURPOSE:To feed a tape in a high speed and to improve the stop precision by converting continuous rotation of a driving shaft to intermitted rotation of a following-up shaft through a cam mechanism, and providing a motor which changes the rotation of tape feeding roll of a differential gear mechanism which uses the following-up shaft as the input shaft. CONSTITUTION:When a driving shaft 51 of a cam mechanism 5 is rotated in a certain speed, a following-up shaft 52 starts rotating gradually and is accelerated and is rotated in a high speed, then is decelerated gradually and is stopped. Further, an output shaft 31 of a differential gear mechanism 3 is rotated intermittently at every certain rotation angle. Therefore, the stop position of a pattern, a mark 11, or the like on a tape press-fitted to a press-fitting roll 21 by a roll 2 is shifted little by little. Consequently, the diameter of the roll 2 is so set that the roll 2 feeds the tape 1 slightly less than the quantity of one feeding of the tape 1, and a stepping moror 4 is driven after or just before the tape 1 is fed by the rotation quantity of the cam mechanism 5, and a gear 32 is rotated by a gear 41 to increase the rotation quantity of the roll 2, and the tape 1 is fed until the mark 11 reaches the front of an optical sensor 8. Thus, the tape is fed in a high speed, and the high stop precision is attained.
