Title: Revolution-angle detecting apparatus
Inventor: KATAGISHI KENICHI
IPC: F02P11/06
Filed: 1984-02-01
Abstract: PURPOSE:To obtain a stable output with a lower power-source voltage by installing a control circuit which does not operate an apparatus at a power-source voltage or less which causes erroneous operation. CONSTITUTION:When light is irradiated into a light receiving circuit 2, and a power-source voltage VC lowers and each standard voltage VR<+>, VR<-> becomes nearly equal, an output generates chattering, since the hysteresis effect due to a resistor Rf is not developed in the state where the power-source voltage VC is low. Therefore, each electric current of photodiodes 10 and 11 is detected by a resistor 12, and the apparatus is controlled so that an output V0 is not operated in the state where the power-source voltage VC is low. For example, when the power-source voltage VC lowers below 2.5V, and the voltage VB applied onto the resistor 12 becomes below a standard value VB (e.g., 1V), the base current of a transistor 43 is ccontrolled by turning ON a diode D2 by a control circuit 4, and the operation of the output V0 is obstructed.

Title: Load current detector and transformer
Inventor: HANEDA SHOJI
IPC: H01F27/00
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To easily, accurately detect a load current with a high sensitivity by a simple constitution without adding a special component separately. SOLUTION: In the transformer T, an input of a power source is supplied to its primary winding Ta, and an output from its secondary winding Tb is supplied to a load. Further, a detecting winding Tc having a predetermined turn ratio to the winding Tb is wound near the winding Ta. When a load current flows to the winding Tb for a load due to a power consumption of the load, a voltage drop occurs between terminals of the winding Tb due to an internal resistance of the winding Tb and a magnetic reluctance of the transformer T. Since no load current flows in the winding Tc, a voltage corresponding to a voltage difference between terminal voltages of the windings Tb and Tc is present between terminals of a voltage detector VD. This voltage corresponds to an amplitude of the load current, and the load current is detected based on the detected voltage of the detector VD.
