Title: Battery ventilation valve
Inventor: CHIYAARUZU PII MATSUKAATONII J
IPC: H01M2/12
Filed: 1988-09-01
Abstract: PURPOSE: To prevent the unnecessary loss of internal gas by performing a reseal at a specific pressure, and releasing a relatively large amount of the internal gas without generating an excessive rise of gas pressure in a battery. CONSTITUTION: An annular elastic skirt 24, in an ordinary operating condition, at pressure set in response to an internal gas pressure acting in an inner side surface, is spread outward almost uniformly, an annular gap 63 between a sealed edge 56 and a tilted outer side sealed surface 22 is opened, gas is allowed to flow in a vent chamber 18 by a relatively low flow amount, to be made to flow out in the peripheral atmosphere. In an abnormal operating condition, by spreading further outward, the gap 63 is spread, a considerable part of gas is made to pass without increasing an internal gas pressure exceeding a preset pressure, when the internal gas pressure is decreased to about 50% the preset pressure or that or more, a condition is returned back rapidly to a closed seal engagement condition.  Setting of the pressure is obtained by moving a seal member 26 in front and back relating to a valve seat 20 of a seal member 26. In this way, an unnecessary loss of internal gas can be prevented.

Abstract: PURPOSE:To sample and hold an input signal at very high speed with high accuracy by equipping the device with an input buffer, a superconducting with composed of a Josephson junction, a magnetic field generator, a hold capacitor, and an output buffer. CONSTITUTION:Input signal voltage is converted into a current in an input buffer 2 and inputted to a superconducting switch 4 composed of the Josephson junction. The superconducting switch 4 is under a superconducting state by a Josephson effect in a sample mode, and a hold capacitor 6 is charged by the current through the superconducting switch 4. In a hold mode, a magnetic field generator 5 generates a critical magnetic field, the superconducting switch 4 shifts from the superconducting state to an ordinary conducting state, the current is interrupted, and the charging for the hold capacitor 6 is stopped. Further, the terminal voltage of the hold capacitor 6, which is held in a constant value, is outputted as held signal voltage through an output buffer 7. Thus, the input signal can be subjected to sampled-held at superhigh speed with high accuracy.
