Title: Brake control device for operatorless electric rolling stock
Inventor: MIYAZAKI YASUYUKI
IPC: B60L7/24
Filed: 1982-07-20
Abstract: PURPOSE:To reduce the damage of electromagnetic brake shoes by shortening the operation delay time from a brake start by a hydraulic brake to the start of the brake by an electromagnetic brake to the normally stopping time at the emergency stopping time. CONSTITUTION:A normal stop command fn is applied to a hydroelectromagnetic brake drive control circuit 10, the circuit first operates a hydraulic brake, operates an electromagnetic brake at the time t2 after the operation delay time td1, and releases the brake at the time t3. On the other hand, when an emergency stop command fi is applied by the detection output from a sensor circuit 18, the operation delay time is set to td2 shorter than the operation delay time td1 at the normally stopping time. Since the electromagnetic brake is not operated in a short time except the emergency time in this manner, the damage of the brake shoes can be reduced, thereby prolonging the lifetime.

Title: Socket for semiconductor ic element
Inventor: IKESUE TAKAO
IPC: H01R33/76
Filed: 1990-05-16
Abstract: PURPOSE:To prevent connection failure to be caused by the occurrence of damage to outer lead wires or by the scraping of solder plating by providing a conductive contact which is rotating in the insertion direction of a semiconductor IC element on which the outer leads are mounted and coming in contact with each of the outer leads. CONSTITUTION:Supporter poles 3 having a spring property are plantedly erected on a socket main body 4, and conductive contacts 2, contacting each of the outer leads 5 of an IC 1, are fitted to the tip of the supporter poles 3. The insertion of the IC 1 causes the rotation of the contacts 2, the outward expansion of the supporter poles 3, and because of the spring property of the supporter poles 3, the outer leads 5 are pressed to the contacts 2 to be electrically connected so as to mount the IC 1 on an IC socket. Because the contacts are rotatable cylinders, the shock due to the contact of the contacts with the outer leads can be relaxed to prevent the occurrence of the connection failure of the IC outer leads, which causes the production of damage to the outer leads or the scraping of solder plating.

Title: Plasma etching device
Inventor: YAMAZAKI TAKASHI
IPC: H01L21/302
Filed: 1980-09-11
Abstract: PURPOSE:To optimize self-bias voltage at the time of etching by mounting a connecting mechanism varying a high frequency-like connection condition between an electrode at the grounding side between a pair of parallel plate electrodes constituting the plasma etching device and a vessel. CONSTITUTION:An etching chamber is composed of the torus-shaped vessel 11 formed by stainless, the discoid parallel plate electrodes 12, 13 and insulating rings 15. The connecting members 16 shaped by bending a metallic plate in a corrugated shape are inserted between an outer circumferential section of the grounding electrode 12 between the parallel plate electrodes and an inner circumferential section of the vessel 11. The grounding condition of the electrode 12 can be changed by the form and number of the connecting members 16. When a gas consisting of a halogen element is introduced into the etching chamber and a material is etched by plasma, etching characteristics depend upon the self-bias voltage, but aimed etching characteristics can be selected by properly setting the grounding condition of the electrode 12 because the self-bias voltage depends on the grounding condition of the electrode 12.

Filed: 1991-05-30
Abstract: PURPOSE:To constitute a telephone conference to be easily used under an ATM communication network by digitally adding subtracting voice signals and forming a voice bridge function by a voice buffer completing transmission for the delay time of one loop. CONSTITUTION:The respective telephone conference devices on the loop are housed in the ATM network and logically connected by an ATM line 3-8. The in-network delay fluctuation of a voice cell from the ATM network is absorbed by an absorbing mechanism 3-7 and transmitted to subtracter 3-5 at fixed speed. The subtracter 3-5 obtains information, which is added and synthesized in the preceding cycle by the own telephone conference device, from a buffer 3-6 completing the transmission and generates the voice cell extracting only the voice information of the other telephone conference device by subtracting and decomposing the information from the information of the voice cell. Voice information adding and synthesizing the voice of the other telephone conference device is reproduced by a D/A converter 3-1. On the other hand, voice information in a cell buffer 3-3 is transmitted to the ATM network after being added and synthesized to the voice cell, which is generated by the subtracter 3-5, of the other telephone conference device by an adder 3-4.
