Abstract: PURPOSE:To ensure generation of the control voltage having a desired temperature characteristics, by providing plural differential amplifiers and arithmetic circuits and thus securing an independent setting of the control voltage such as the bias voltage and the like at each control temperature point. CONSTITUTION:A certain level of voltage divided by the resistances R7 and R8 is applied to the positive input terminal of operational amplifier OPA, and the voltage controlled by variable resistances RV1-RV3 is applied to the negative input terminal via resistances R3-R5. Thus an adder circuit is formed. At the same time, the outputs of differential amplifiers DFA1 and DFA2 are applied to resistances RV1 and RV3, and the voltage controlled by resistances RV1 and RV3 is added with the voltage controlled by the resistance RV2. If the resistance value of thermistor S at the reference temperature is equal to the resistance R1 and the resistance value of posistor P is equal to the resistance R2 with the normal temperature set as the reference level, both points (a) and (b) are set at O-potential. Thus the outputs of DFA1 and DFA2 are set zero. Accordingly the control voltage proportional to the voltage controlled by RV2 is delivered.

Title: Magnetic control type gas bearing
Inventor: OKANO MAKOTO
IPC: F16C39/06
Filed: 1979-05-11
Abstract: PURPOSE: To reduce a starting torque as well as prevent damages of a shaft and a shaft surface by a method wherein a distance between a shaft and a shaft surface is detected by a position detecting element, and the change is compensated by an electromagnet and a current control.  
     CONSTITUTION: In supporting a load in the thrust direction, when the number n of rotations of a shaft is lowered to decrease the load capacity, a distance C 1  between a thrust receiver plate 4 and a thrust gas bearing 5 will be forced to be shortened so that a thrust force F and the load capcity can be balanced. The change of the distance C 1  is detected by a position detecting element 1 and transmitted to a current control device 6. The current control device 6 flows current equivalent to the change of the distance C 1  to a coil winding 2 of an electromagnet M to increase a magnetic support and compensate the d4crease of the load capacity. In this system, since the solid contact is not given when the shaft starts or stops, damages are not caused and the starting torque is lowered.
