Title: Bridge circuit
Inventor: MIZUTA TSUNEO
IPC: H02P7/03
Filed: 1992-02-27
Abstract: PURPOSE:To provide a bridge circuit which responds at a high speed by driving an H bridge circuit directly by an output of a drive circuit, in a DC-AC converter. CONSTITUTION:An H bridge is constituted of a DC motor 1 and FETs 4A to 4F for driving the DC motor 1, to connect a DC power supply 17 in parallel to the H bridge. Further, the FETs 4A, 4C are used to serve as P gate FETs, and the FET4B, FET4D to 4F are used to serve as an N gate FETs. Here, relays 2A, 2B are actuated by an external signal to switch a DC power supply 5 for on-off turning the FETs 4E, 4F, and a potential difference is generated between gate/source of the FET depending on the voltage division ratio of resistors 3A to 3D and resistors 3E to 3H, to switch the direction of rotation of the DC motor 1 by turning the FET on-off. In this way, a circuit scale can be contracted by simplifying an FET driving circuit without using a transformer.

Abstract: PURPOSE:To reduce the error of rotating angle detection of a rotor, which is obtained by detecting the oscillation of a traveling wave in the rotor, by a method wherein the dividing of electrodes of an oscillator and the direction of polarization are made so as to be a predetermined pattern. CONSTITUTION:An electroconductive thin film is formed on the surface of an oscillator 1-3 or a piezo-electric element while the film is divided into electrode parts 2-3 corresponding to 1/4 wavelength through insulating unit 2-4. When these parts are connected one by two, the direction of polarization of + - are developed alternately. Remaining electrodes are treated in the same manner. An interval between alternate electrodes becomes 1/2 wavelength and the direction of polarization becomes revered whereby the arrangement of the electrodes are corresponding to the recesses and projections of one set of stationary wave in order to oscillate another stationary wave even though the parts of electrodes corresponding to 1/4 wavelength are omitted. It is the same in remaining electrodes. According to such division of electrodes and the directions of polarizations, two sets of stationary waves can be oscillated independently and alternately with an interval corresponding to 1/4 wavelength.

Abstract: PURPOSE: To unlock the steering lock of an automobile and start an engine without using a key only by pushing several buttons by associating an electronic controller with an actuator.  
     CONSTITUTION: When the steering wheel is locked to keep an engine in a stopped condition, since a control rod 7a is inserted into a locking recess 6a of a rotator 6, the engine cannot be started by rotating a knob 1. In order to start the engine, certain signals are outputted by pushing buttons 3a to 3e of the electronic controller C in accordance with codes stored in a memory unit, the actuator 7 is supplied with power for a predetermined period of time so as to attract the control rod 7a. Therefore, the rotator becomes free and an ignition switch becomes operable. When the power supply is interrupted, the control rod 7a advances into a wide recess 6b and accordingly the operation becomes possible within a range from ACC to START. If the knob 1 is pulled on the ON position, a projection 5a enters into a recess 4a of a lock body 4. Thus, the control rod 7a is attracted for a while by a switch 9 and a timer 10, during which the lock can be rotated to the LOCK position.
