Title: Metallic die for piercing or rear part extrusion
Inventor: MATSUNAGA SHUICHI
IPC: B21J5/06
Filed: 1987-01-29
Abstract: PURPOSE:To increase the buckling stress of a punch and to enable the piercing having larger deep hole ratio by arranging an intermediate punch guide vertically movably between the punch fitting part of an upper die and punch guide bush holder. CONSTITUTION:An intermediate punch guide 33 is arranged between the punch fitting part 6 of an upper die 31 and a punch guide bush holder 8 of the die for piercing forming a hollow body by pushing a punch 5 into a blank 25. This guide 33 is provided movable in the axial line direction of the punch 5 by holding the shank part 5a of the punch 5 by its guiding. Owing, therefore, to the buckling stress fo the shank part 5a of the punch being able to be increased piercing can be performed even for unworkable one whose deep hole ratio (product length/inner diameter) is more than five and the improvement in the productivity and cost down can be realized.

Title: Copying machine
Inventor: TAJIMA HATSUO
IPC: G03G15/22
Filed: 1980-02-18
Abstract: PURPOSE:To obtain a copied picture with invariably uniform density, by gradually increasing the gap between a corona discharger and photoreceptor surface. CONSTITUTION:The diameter of roller 3a at the side of cleaning device 9 is made smaller than that of the other roller 2, and while axial cores of both rollers 2 and 3a are arranged in parallel to the same plane, photoreceptor 1 slants down from point A to point B. The gradient of photoreceptor 1 is so determined that points A and B will be held equal in electrostatic latent image potential during development; for example, photoreceptor 1 slants so that distance D between the flank of shielded case 4a and the surface of photoreceptor 1 will be 2mm. at point A and 4mm. at point B in the figure. Further, a corona applied voltage is set to 6.0kV. As a result, the charging potential decreases gradually between points A and B during  the development processing, the electrostatic latent image has a uniform potential  over the entire area.

Title: Serial-parallel conversion circuit
Inventor: UMEZAWA YOSHIAKI
IPC: H03M9/00
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To reduce as much as possible the number of FFs(flip flops) which simultaneously operate for reducing noise and to improve reliability by responding to the rise of one corresponding 2nd clock signal among n pieces of 2nd clock signals that successively rise at the time of every rise of a 1st clock signal, storing data that corresponds to an output from a data-receiving circuit and performing a parallel output. SOLUTION: A D-type flip-flop(FF) 110 stores and outputs a bit that is received by a serial-parallel input terminal, in response to the shift of electric potential of a serial clock signal, here, to its rise. An n-bit parallel conversion circuit 120 consists of D-type FFs 121-1 to 121-n, has 1/2n frequency of a serial clock signal and separately inputs n pieces of parallel clock signals, which are sequentially delayed by one cycle of the serial clock signal to input terminals 105-1 to 105-n. Through this, all the FFs do not operate at the same time, operation noise is reduced, and a circuit structure is also simplified.

Title: Interphone device
Inventor: MATSUDA MITSUHIRO
IPC: H04M9/00
Filed: 1989-01-31
Abstract: PURPOSE:To precisely perform state identification without being affected by the number of slaves connected to a speech line by performing the short-circuit connection of the speech line with prescribed impedance by the slave corresponding to the operation of a call switch. CONSTITUTION:The speech circuits SN1-SNn of the slaves 5-1 to 5-n are connected to the speech line 3 via diode circuits DB-DBn.

Also, the voltage of the speech line 3 is prevented from being lowered than the voltages in forward direction of the diode circuits DB1-DBn in spite of the connecting number of slaves 5-1 to 5-n. In such a way, the state identification can be performed precisely in spite of the number of slaves 5-1 to 5-n.

Title: Back-up memory for electronic equipment
Inventor: IWAMOTO YOSHIMI
IPC: G06F12/16
Filed: 1988-01-29
Abstract: PURPOSE:To ensure the writing of data when a voltage drop is detected by performing the writing control of the prescribed data to a memory means when the voltage of a low level is detected and only when a period when no voltage drop is detected is longer than the charging time of a back-up power supply part. CONSTITUTION:An arithmetic control means 9 performs no writing control to a memory means 8, if a period when the drop is not detected for the power supply voltage counted by a clocking means 11 does not exceed the charging time of a back-up power supply part 10 for the satisfactory writing control in case the voltage of a low voltage is detected by a low voltage detecting means 7. As a result, the writing control is carried out only when the part 10 is satisfactorily charged. Thus, it is possible to avoid the writing failure of the prescribed data to the means 8 due to the drop of the voltage level of the part 10.

Title: Method for bending and post processing suturing needle with cutting edge and its post processing device
Inventor: MATSUTANI KANJI
IPC: B21G1/02
Filed: 1990-02-01
Abstract: PURPOSE:To prevent a damage from being generated through a bending die on a cutting edge by sticking elastic members on the cutting edge formed previously on a stock for a suturing needle. CONSTITUTION:In bending, the cutting edge 1a formed on the stock a comes in contact with dies 3a, 3b through elastic members 2. In other words, the bending force given by the dies 3a, 3b to the stock (a) acts through the elastic members 2. For this purpose, the elastic members 2 works as a cushion and the bending force acts uniformly on the stock (a). Consequently, force does not act concentrically on the cutting edge 1a of the stock (a) and a damage such as a collapse and a burr is not generated on the cutting edge 1a.
