Title: Magnetic bearing
Inventor: WAKAHARA KOUJI
IPC: F16C32/04
Filed: 1980-08-07
Abstract: PURPOSE: To heighten stability against the change in temperature, by providing a plurality of magnetic members, which are different in Curie point from each other, on the magnet-facing surface of a magnetic bearing which supports a vertical rotor.  
     CONSTITUTION: Three annular magnetic members 6W8, which have high magnetic permeability and are slightly different in Curie point from each other, are stratified on the surface of a static magnet 4 which is located on a magnetic gap. When the temperature of each of the magnetic members 6W8 has exceeded its Curie point, the magnetic performance falls sharply and the permeability becomes approximate to zero. For that reason, the gap between magnets 4, 2 varies depending on the change in the temperature. The thermal elongation of a rotor 1 is taken into consideration to appropirately set the thickness of the magnetic members 6W8 to keep the gap between the magnets 4, 2 constant despite the rise in the temperature. This results in heightening the stability of the rotor 1.

IPC: F15B15/28
Filed: 1989-04-27
Abstract: PURPOSE:To prevent a set range from being affected by temperature variation by providing a temperature compensating means at the amplification part for the signal of a sensor which detects the position of the actuator. CONSTITUTION:A sensor part 1 consists of an MR element and outputs a volt age corresponding to whether a magnet packaged on the actuator moves to or away from the sensor part to display the position of the actuator. The ampli fication part 2 amplifies the output, and sends a specific output signal when the output exceeds a specific value to make red and green LEDs of the tempera ture compensation part 3 radiate corresponding to the specific range. A tempera ture compensation part 3 is connected to the amplification part 2. Then if the sensor output varies with the ambient temperature, the compensation part 3 functions to suppress the variation and equalize the low-temperature and high- temperature sensor characteristics to those at reference temperature, so the set range is not affected by the temperature variation.

Abstract: PURPOSE:To make a clear normal/abnormal decision by feeding the output voltage of a converting circuit back to a frequency dividing circuit through a setting circuit, and lowering the output of a frequency signal to zero and resetting the frequency dividing circuit when a DC level is lower than a set voltage. CONSTITUTION:The crystal oscillator is oscillated by an oscillation circuit 1 to generate an output waveform having a difference in amplified according to the value of a loss resistance R1. This waveform is inputted to an R1 detecting and converting circuit 2, which converts the input to a DC level propor tional to the amplitude and outputs the DC level as R1OUT to the setting circuit 3. The set voltage corresponding to the DC level is set in the circuit 3 and when the DC level is lower than the set voltage, the output signal is lowered to zero to reset the frequency dividing circuit 3, whose output frequency signal F0OUT is lowered to zero. Then the value of the resistance R1 can be set option ally. Consequently, quality standards can be divided into stratums and a clear normal/abnormal decision can be made.
