Abstract: PURPOSE:To compose a three-wiring type differential transformer of two windings and to prevent the occurrence of an error originating from ambinet temperature and connecting cord length, by performing the quotient arithmetic of the difference and the sum between terminal voltage of two secondary windings through the middle point. CONSTITUTION:A differential transformer converter 1 buried under the ground and used for a long period consists of a primary coil 6, a movable magnetic core 5, secondary windings 2 forming two coils 2a and 2b across the middle point, etc. The terminal voltages and B of those coils 2a and 2b increase and decrease reversely according to the movement of the cil 6 and their sum voltage A+B is unchanged, so that even if a current varies owing to fluctuations of temperature, etc., the voltges A and B are in proportion to a current flowing through the winding 6. Further, the load impedance ratio of connecting cords of the coils 2a and 2b symmertical to the middle point is constant without reference to their cord lengths. Therefore, the three-winding type differential transformer is composed of two windings and the occurrence of an error in measured value which is obtained by the quotient arithmetic of a difference voltage A-B and sum voltage A+B by an arithmetic device and corresponds to the movement of the magnetic core 5 due to fluctuations of ambient temperature and connecting cord lengths is prevented.

Abstract: PURPOSE: To maintain the car height at a level suitable for running the car regardless of conditions of a road (a paved road, a very bumpy mountain road, and so on) to prevent a trouble such as by contact of a bottom part of a car body with the road by providing for designation of a desired one of a plurality of car height references.  
     CONSTITUTION: A disc 14 constituting a car height detecting portion 13 is provided on a link mechanism 12 connected to a shaft 11. The disc 14 is rotated by the link mechanism 12 which converts a change in the car height, that is, a change in a linear distance in the vertical direction between a car body 8 and the shaft 11, into a change in a rotational angle of the disc 14. Upon rotation of the disc 14, a light detecting condition of light receiving portions R1WR3 of the detecting portion 13 is caused to change by light shielding portions V1WV3 whereupon a logical output corresponding to the car height is obtained from the detecting portion 13. This car height signal is compared at a comparator means 9 with a reference car height signal preset by a switch 16, and a switch 10 is turned on depending upon a deviation between the two signals to activate a compressor 3 to extend a shock absorber 1 or to open an exhaust valve 6 to contract the shock absorber 1 to thereby adjust the car height.
