IPC: H01L27/04
Filed: 1985-07-15
Abstract: PURPOSE:To limit the voltage of a substrate at a desired level even if the voltage of a power supply increases by connecting the third transistor whose threshold is higher than that of the second transistor between the connecting point of the second transistor with the substrate and the VSS power supply terminal. CONSTITUTION:An enhancement type N channel MOS transistor T3 is connected between the connecting point of a transistor T2 with a substrate and the VSS power supply terminal. In this circuit, when the potential VA is negative, the transistor T2 is forward-biased so that the transistor T2 is turned on, with the charge pump current I2 flowing from the substrate through the transistor T2. At this time, when the absolute value ¦VBB¦ of the potential of the substrate is larger than the threshold value VTH3 of the transistor T3, the compensation current I3 flows into the substrate from the VSS power supply terminal (GND) through the transistor T3. In other word, electrons are discharged from a load capacitor C2 through the transistor T3, with the absolute value ¦VBB¦ of the potential of the substrate limited at a desired level.

Abstract: PURPOSE: To select design parameters of a gerotor gear set by repeatedly adjusting one of a tip radius and a gear cutting radius till both of a single point clearance and a double point clearance become roughly similar to a desired tip clearance within a permissible tolerance. CONSTITUTION: A desired radial tip clearance TC between external teeth 19 (in the number of N with a tip radius of TR) of an inner rotor 17 and internal teeth 15 (in the number of N+1) of an outer rotor 13 is selected. Next, either of the tip radius TR and a gear cutting radius GR is repeatedly adjusted for similar or less quantity to difference between the desired tip clearance TC and either of a single point clearance SPC and a double point clearance DPC. While constantly monitoring the clearances SPC and DPC as a result, above procedures are repeated till the clearances SPC and DPC become roughly similar to the clearance TC (within a specified permissible tolerance). Design parameters in which both the clearances SPC, DPC become mathematically equal to the desired tip clearance TC can thus be obtained.
