Title: Sorting of non-linearity resistor
Inventor: SAKURAI ZENJI
IPC: H01C17/00
Filed: 1990-02-28
Abstract: PURPOSE:To sort a non-linearity resistor being partially non-uniform without seriously damaging the non-linearity resistor by determining only how much the current value detected at each small electrode of square wave or impulse surge applied from each small electrode and an electrode corresponding to the small electrode to each part of the non-linearity resistor is different from the mean value thereof. CONSTITUTION:Small electrodes 2 are respectively provided with current detectors 3 and connected in common with a square-wave surge-applying power supply 4. Also, electrodes 7 are connected with the surge-applying electrode 4 in the same way as the small electrodes 2, installed at an electrode contact- bonding mechanism 9 via jig 8 and contact-bonded to the other surface of a non-linearity resistor 1 by this electrode contact-bonding mechanism 9. Further, the current detector 3 of each small electrode 2 is connected with a current value computer 11 via an integrated oscillograph 10. This current value computer 11 calculates the mean value of a current flowing to the current detector 3 of each small electrode and determines how much the current value detected by the current detector 3 of a specific small electrode 2 deviates from the mean value, to classify the current value.

Title: Vacuum breaking device
Inventor: FUJIWARA YUKIO
IPC: G21D1/04
Filed: 1980-04-09
Abstract: PURPOSE: To provide a vacuum breaking device applied to a reactor by a method wherein a moving means is moved under its spiral rotation in the valve box in a differential pressure, the valve body is opened or closed with its rotational force, thereby a small-sized and light weight pressure control container having a decreased shock caused when the valve is closed rapidly.  
     CONSTITUTION: When the pressure difference is applied against the moving body 5, the moving body 5 is moved toward a negative pressure side along with a valve body 7. During this movement, the moving body 5 is moved in a spiral direction  along the spiral guide 4, thereby a rotation is produced. Thus, the valve body 7  fixed to the moving body 5 by a pivotal axis 8 is also moved in the same direction  as above. However, the valve body 7 is rotated in a clockwise direction in a drawing under a relative movement of the fixing axis 11 inserted through the sliding  longitudinal hole 10 to open the valve body 7. In turn when the differential pressure is made to be opposite, the moving body 5 is moved to rotate in an opposite  direction to cause the valve 7 to be closed. In this way, it is possible to provide the  small-sized vacuum breaking device enabling to decrease a shock generated when  the valve is closed rapidly.
