Inventor: MATSUMOTO TAKAHIRO
IPC: G01N29/12
Filed: 1990-11-27
Abstract: PURPOSE:To ensure a large signal strength by generating resonance of ultrasonic waves inside a thin film by applying a burst pulse laser light to the thin film with the period of a pulse train of the like varied. CONSTITUTION:A light modulator 3 and a light chopper 4 are disposed sequentially on an emission optical path of a laser 1 for generating resonance ultrasonic waves, and a modulated laser light is applied onto the surface of a thin film 5. The laser light is generated by exciting the laser 1, the light is subjected to light modulation by the light modulator 3 and applied onto the surface of the thin film 5, so as to give a thermal stress to the part of it, and thereby ultrasonic waves are generated. Moreover, a burst pulse is generated from a pulse laser by a combination of an electrooptic element with various elements, the period DELTAT of a pulse train of thin burst pulse laser light is varied and thereby a primary or secondary resonance ultrasonic waves are generated inside the thin film. According to this constitution, a very large signal strength can be obtained by utilizing resonance.

Title: Electromagnetic flowmeter
Inventor: TOMITA TOYOFUMI
IPC: G01F1/58
Filed: 1989-12-12
Abstract: PURPOSE:To make the apparatus compact and power-saving by providing a magnetic path switching means for periodically switching a magnetic field of a permanent magnet to a first or a second magnetic path with a substance for generating a re-arranging phenomenon of a magnetic spin by heat, and a heating means for heating the substance. CONSTITUTION:A spin re-arranging substance 14 is heated by a heating element 15 for every fixed cycle. Switches 20, 22 are alternately turned ON and OFF in a synchronous manner with the heating timing. While the substance 14 is not heated, since an axis of easy magnetization extends in an up-and-down direction, the magnetic resistance in a direction of a magnetic core 16 is large. Therefore, the electromotive force of a signal having a signal proportional to a magnetic field (b) and the average velocity of a fluid within a duct 11 overlapped with a polarization voltage of an electrode 17 is generated in the electrode 17 of the duct 11. The electromotive force is accumulated in a capacitor 19 as the switch 20 is kept ON. When the substance 14 is heated, the axis of easy magnetization is in the direction of the core 16, so that the magnetic field induced to a core 12 becomes weak and the electromotive force is accumulated in a capacitor 21 while the switch 22 is turned ON. Accordingly, the difference of the charges of the capacitors 19, 21 is amplified in a differential amplifier 23, and a signal (g) proportional to the average velocity of the fluid is taken out.

Title: Horizontal deflection circuit
Inventor: OTA MASUTOMI
IPC: H04N3/16
Filed: 1988-12-21
Abstract: PURPOSE:To suppress the generation of ringing by making the current of a damper period, for which the forward direction voltage of a parasitic diode in a power MOS.FET reaches a forward direction saturation voltage, flow as a drain current in the reverse direction of the power MOS.FET. CONSTITUTION:The subject circuit is provided with a means 18 to slice a fly- back pulse and means 15-17 to shape the pulse to a rectangular wave and detect the fall of the rectangular wave and means 12-14 to fall the drive pulse by the falling of the rectangular wave and add a voltage to the gate of the power MOSFET 6 and turn on the power MOSFET 6 as a reverse transistor simultane ously when the gate voltage rises and a fly-back period is finished. A positive bias is impressed between the gate and source of the power MOS.FET 6 from the middle of the fly-back pulse and the input capacity of a gate terminal is charged. Thus, the current of the damper period flows as the drain current in the reverse direction not to be proportional to the source drain voltage at first. Then, since the current does not immediately flow, the ringing is suppressed.

Abstract: PURPOSE: To improve frequency transmission characteristic of a surface acoustic wave transducer by providing a reflector outside the input and output electrodes. CONSTITUTION: Interdigital input electrodes 12 and output electrodes 13 are arranged on a piezoelectric substrate 11 opposite to each other.
