Title: Press forming device
Inventor: ITAKURA KAZUMI
IPC: B30B15/00
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To reduce an impact sound generating at the time of working by providing a through-hole piercing through a cushion plate in a position where a die side cushion pin and a machine side cushion pin face each other, mounting an urethane block in the through-hole, and making both upper and lower dimensions of the urethane block longer than the thickness of the cushion plate. SOLUTION: When a cushion ring 5 holding a blank 4 is pushed downward by an upper die 1, the urethane block 9 in the through-hole 71 is compressed by the die side cushion pin 51. The repulsion force of the block 9 is increased by the cushion force of the machine side cushion pin 61, the cushion plate 7 is lowered, and the blank 4 is worked between the upper die 1 and a punch 3. Since the plate 7 is decelerated, the impact sound is reduced. The block 9 is compressed until the pins 51 and 61 come into contact with the plate 7. The intermediate part of the through-hole 71 is formed to be a large diameter, and the block 9 projects into the large diameter part, and the shift of the block 9 in the through-hole 71 is prevented.

IPC: H01S5/00
Filed: 1991-12-25
Abstract: PURPOSE:To develop a novel manufacture of a lead sulfide semiconductor device having a mesa part which does not necessitate mesa etching and has an excellent shape and a clean surface. CONSTITUTION:A metal mask 2 having an opening 3 is formed on a first semiconductor layer 1. Then, a second semiconductor layer 4 constituted of a lead sulfide semiconductor is formed. The second semiconductor layer 4 is deposited inside the opening 3 and on the upper surface, in the main, of the metal mask 2. The second semiconductor layer grows epitaxially inside the opening of the metal mask, while it becomes polycrystalline and is not deposited closely on the metal mask other than the part of the opening. Therefore it can be removed easily by etching the metal mask. By etching the metal mask selectively, only the part of the second semiconductor layer 4 in the opening is left behind and a mesa part 5 is formed.

IPC: H02P8/22
Filed: 1991-12-26
Abstract: PURPOSE:To simplify the circuitry and to realize considerable cost reduction by storing the variation of phase current due to the variation of ON/OFF duty, in the form of data, and subjecting an output element to ON/OFF duty control based on thus stored data when an exciting sequence is executed. CONSTITUTION:ON duty of an output element Tr 9 is gradually increased from 0% to 100% based on data stored in a memory thus gradually increasing the driving current of phase E. At an instance when ON duty of the output element Tr 9 reaches 100%, ON duty of an output element Tr 1 begins to decrease gradually from 100% to 0% and thereby the driving current of phase A decreases gradually. Excitation is carried out sequentially in such a manner. The output elements are subjected to ON/OFF switching control according to a predetermined sequence and ON duty of control output element is varied according to ON/OFF duty data stored in a memory thus performing micro angle driving.

Abstract: PROBLEM TO BE SOLVED: To provide a means for readily eliminating uneven brightness caused by the unequal lengths of optical fibers. SOLUTION: A light-emitting surface device includes a device main body including a luminous surface 1. The device includes a light-source 2. The device includes a number of optical fibers 3 whose light input ends are connected to the same light source 2 so that light is input to them.
