Title: Optical switch device
Inventor: ARAI AKIFUMI
IPC: H03K17/14
Filed: 1989-09-13
Abstract: PURPOSE:To accurately determine the relay operation voltage by connecting Zener diodes in series between a photo diode and a power source and immediately turning off the Zener diode at the time of reduction of the power source voltage to a value lower than the threshold of the Zener diode. CONSTITUTION:When voltages of a first power source +VCC and a second power source -VCC are supplied with normal voltage values, photo transistors TRs TR1 and TR2 are turned on and a relay K is operated to turn on contacts K1 and K2 because the light from photo diodes U1 and U2 is supplied to TRs TR1 and TR2. Voltages of power sources +VCC and -VCC are supplied to the IC connected to contacts K1 and K2. If the voltage of the power source +VCC or -VCC is reduced to a constant voltage or lower, diodes U1 and U2 are turned off because a Zener diode CR1 or CR2 is turned off. Thus, the relay K is surely turned off, and contacts K1 and K2 are kept turned off to protect the IC.

Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To keep the temp. of a supply stream high without requiring high vacuum by supplying a vaporous mixed supply substance to the supply side of a membrane while allowing a sweep stream of condensible vapor to flow countercurrently and transferring steam to the transmission side of the membrane to form a non-condensed transmission side mixture before separating water. SOLUTION: A supply stream 10 containing steam and a waste vapor component is supplied to a membrane module 25. A condensible sweep stream 32 is supplied to a vapor inlet opening in the vicinity of the holding end of the membrane module 25 on the transmission side of the module 25 as a countercurrent stream. Whereupon, stream is selectively removed from the supply stream within the membrane module 25 to form a holding stream 14 deprived of a component A. the condensible vapor sweep stream 32 is mixed with a vapor transmitted substance rich in steam transmitted through the membrane of the module 25 to become a transmitted mixture which is, in turn, discharged from the vapor outlet opening provided in the vicinity of the supply end of the module 25. By this constitution, the flow rate of a transmitted stream is increased by the increase of propelling force.

IPC: H04L12/70
Filed: 1988-09-20
Abstract: PURPOSE:To improve the throughput of a communication network as a whole by limiting the continuance of the overflow of a reception buffer by providing a selective reception mode to receive and transfer only a packet addressed to one of terminals to be housed selectively. CONSTITUTION:A group reception mode to receive and transfer all arrival packets addressed to either the terminals to be housed, and the selective reception mode to receive and transfer only the packet addressed to one of the terminals to be housed selectively are provided in packet reception. Also, a threshold value A and a value B larger than the threshold value A are decided for the packet accumulation quantity of a packet reception buffer. When the packet accumulation quantity is increased from the value less than the value A to the one exceeding the value B, the destination address of the terminal A is held, and a mode is switched to the selective reception mode to receive and transfer only the packet having a held destination address selectively. In such a way, it is possible to relax the concentration of re-transmission bursts on the same node, and to improve the throughput of the communication network as a whole by shortening the duration of the overflow of the buffer.

Title: Method and device for igniting ignitable gas generating material
Inventor: GUREGORII ESU BEIREE
IPC: B60R21/26
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To ignite a gas generating material body by dispersing combustion products above the ignitable surface portion of the gas generating material body and to quickly and approximately uniformly ignite an ignitable gas generating material by moving a pyrotechnic material body for dispersing the combustion products. SOLUTION: When pyrotechnic material in a squib 170 in an inflator 14 is ignited and a charge pellet 202 burns, a gas generating material body 60 is ignited under the influence of combustion products generated. The combustion products moving in the opposite direction from the pellet 202 mainly enter a compartment 162 in the closure cap 56 of the inflator 14 and cause a thrust to act on the pellet 202. The pellet 202 is thereby propelled toward the other end and thus moves along the length of the ignitable surface of the gas generating material body 60 while burning to disperse the combustion products over the entire area of the ignitable surface.
