A magnetic field is generated in a core 2 by the high frequency current, as a result of this, electromotive force is excited on a second conductor 20, a current flows in resistance R, and voltage according to the current quantity is generated on both ends of the resistance R. By reading a voltmeter, voltage on both ends of the resistance R is grasped, the current flowing in the resistance R, namely the current flowing in the second conductor 20 is grasped. By previously obtaining relation of current quantities of both conductors 10, 20 by experiment, from the current quantity of the second conductor 20 the current quantity of the first conductor 10 can be obtained.  As a result, the quantity of high frequency current flowing in the circuit conductor P can be detected.

Title: Nitrogen generator
Inventor: YAGIMURA NOBUYUKI
IPC: F25J3/04
Filed: 1995-03-17
Abstract: PURPOSE: To lower consumed power in a nitrogen generator for supplying nitrogen gas of high pressure and high purity. CONSTITUTION: A nitrogen generator is designed to compress feed air in the first to third stages of a feed air compressor 1 and obtain nitrogen of high purity and high pressure as a product under rectification and separation in a cold reserving tank 3.

Filed: 1979-05-15
Abstract: PURPOSE: To prevent the decrease in measurement accuracy by controlling the other input of a synthesizing circuit according to the output of the synthesizing circuit of which one of the inputs is receiving pulses, and generating measurement timing signals.  
     CONSTITUTION: The detecting pulse Q corresponding to the receiving pulse output by a detecting circuit 5 is applied as one input to a synthesizing circuit 10. The pulse Q output by this circuit 10 generates the square wave pulse at which the bistable multi 12 is turned ON and OFF by the decision pulse of the threshold value or more and transmission pulse, and according to the ON-OFF section, the integrated output in the positive and negative directions is applied from an integrating circuit 13 to the circuit 10 as the other input. This causes the circuit 10 to apply the pulse Q corresponding to the reference value even when it changes from the specified reference value owing to a change in reflectance, transmitter-receiver sensitivity, etc., to a measuring timing signal forming circuit 14. Hence, the decrease in measurement accuracy is prevented and accurate distance measurement may be performed.

Filed: 1995-03-17
Abstract: PURPOSE: To eliminate the imbalance of an actuator easily with a simple structure by arranging a sleeve to have a hole in a side wall in the direction of canceling the imbalance of an actuator assembly. CONSTITUTION: A hole 73 is formed in a side wall of a sleeve 72 in the direction of canceling the imbalance of an actuator assembly 22. That is, a bearing unit 62 is caused to be unbalanced positively thereby canceling the imbalance of the actuator assembly. To be more specific, when an FPC42 is fixed on the side of an actuator block 29, the center of gravity of an actuator arm unit 26 shifts to the fixed side of the FPC42 from the center of rotation thereof. Thus, the hole 73 is formed in the side wall of the sleeve 72 on the fixed side of the FPC42 to cancel the imbalance of the actuator assembly 22.
