IPC: H03K19/00
Filed: 1981-09-30
Abstract: PURPOSE:To sufficiently increase the logical amplitude with a single power supply, by connecting the source of a driver FET of a plurality of inverters in cascade connection and in common and floating the source potential from a low potential terminal of a power supply with a diode. CONSTITUTION:Inverters in which normally-on Schottky gate FETsQ21-Q23 are taken as drivers and drains are connected to high potential side via current source load FETsQ24-Q26 are in cascade connection via Schottky diodes D21- D23 for level shift. Sources of the FETsQ21-Q23 are connected in common and the source potential is connected to a Schottky diode D31 to be floated from the ground potential. Since a level shift voltage of each stage is kept constant, FETsQ27-Q29 are connected as a current source with small current value in comparison with the Q24-Q26. The current flowing to the diode D31 is a sum of currents flowing to the Q24-Q26 at all times to be constant, the current acts like a constant voltage, and pinch-off voltage of the FETs is about -0.8V and the logical amplitude is about 1.6V.

Title: Opening-closing device for contact point
Inventor: YOSHIDA KAZUHISA
IPC: H01H1/50
Filed: 1987-06-23
Abstract: PURPOSE: To extend life and improve reliability of a contact point by attaching movable twin contact points to a contact plate attachment plate made of a temperature sensing element which deforms according to temperatures and setting the direction of deformation of the attachment plate at high temperatures in the direction to increase the pressure between a fixed contact point and the movable contact point.  
     CONSTITUTION: Twin contact points 4, 5 are attached via a contact point attachment plate 7 made of a temperature sensing element which deforms according to temperatures such as for example bimetal to a movable contact point spring 6. While the contact plate attachment plate 7 is flat at normal temperatures, it deflects at high temperatures in the direction to increase contact pressure between a fixed contact point 2 and movable twin contact points 4, 5. Under a high temperature of 100°C for example, the contact point attachment plate 7 deflects toward the fixed contact point 2 side to increase the contact point pressure under a closed contact point condition. Positions of contacts between contact points at normal and high temperatures also shift. Constituting in this way, damaged portions on the contact point are dispersed to extend life and to improve reliability.
