Patent JP-H07324967-A (JP)
Title: Load sensor
Inventor: AOSHIMA HIDEYUKI
IPC: G01G3/15
Filed: 1994-06-02
Abstract: PURPOSE:To stabilize the operation, while simplifying the circuitry, by employing a pulse signal as an exciting signal being applied to the primary winding of a magnetostriction element thereby keeping the signal voltage being applied to the primary winding constant regardless of temperature variation, for example. CONSTITUTION:Primary and secondary windings 2a, 2b of a coupling circuit 2 are coupled magnetically through a magnetostriction element 1 and a pulse signal, turning on/off with a predetermined period, is applied as an exciting signal to the primary winding 2a from a pulse generator 3. The element 1 varies the permeability depending on the load being applied to induce a signal in the secondary winding 2b. A detector 5 multiplies the signal induced in the secondary winding 2b by a signal appearing across a resistor 4 and detects the multiplied signal to reduce the mixed noise component before feeding the DC component to a V/F conversion circuit 6. The conversion circuit 6 outputs a pulse having period corresponding to the voltage of DC component and expresses the frequency-variation thereof in terms of weight. This circuitry stabilizes the operation as compared with a case employing a sine wave signal without requiring any feedback circuit.

IPC: G01N29/24
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To scan a plurality of ultrasonic beams at high speed even by phased array method by receiving an electric signal to a reflected ultrasonic signal from a specimen every oscillator. SOLUTION: A random signal waveform X(t) adapted from the generated electric signal of a transmitted waveform generating circuit 10 is supplied to oscillators a1-an as transmitted signal waveforms X1 (t)-Xn (t) through each transmission delay circuit 12 and each transmitter 12. Each oscillator excites the ultrasonic signal of random burst waveform and propagates a composed wave front based on phased array method to a specimen. Each oscillator then receives the received signal waveforms Y1 (t)-Yn (t) corresponding to the reflected ultrasonic signals from the specimen in different times, and each receiving delay circuit 21 delays them by the same phase delay quantity as in transmission.  A phase adding circuit 22 adds them so as to arrange the receiving times reversely to those in transmission, and an arithmetic processor 24 determines an arithmetic signal waveform RXY(t) from the added signal waveform Y(t). This operation is repeated while successively switching each oscillator by a switching circuit 2, whereby ultrasonic beams can be scanned at high speed.

Title: Duty controller
Inventor: ZAIZEN KATSUNORI
IPC: H02M1/08
Filed: 1983-07-04
Abstract: PURPOSE:To obtain a miniaturized duty controller which has an extremely stable cycle of oscillations with a low cost by connecting a thyristor in parallel to a time constant circuit and at the same time actuating a comparator with voltage. CONSTITUTION:With connection of an AC power supply 1, the ripple voltage superposed by the ripple is producd at a capacitor 31 of a ripple voltage generating circuit 25. At the same time, a capacitor 28 of a time constant circuit is also changed. When this charging voltage is higher than the voltage at a point A by the base-emitter voltage VBE of a transistor (TR)18, the TR18 of a comparator 24 is turned on. Thus the electric charge of the capacitor 28 is discharged to the gate of a thyristor 3 from the TR18 via a resistance 17 as well as to the base of a TR17 via a resistance 22. Both the thyristor 3 and the TR17 are turned on. Then the capacitor 28 is discharged. When this voltage is less than the level equal to the value obtained by adding the VBE to the value obtained by dividing the ripple voltage by the compound resistance of resistances 19-21, the TR18 is turned off. Then both the thyristor 3 and the TR17 are also turned off, and the capacitor 28 is charged again. A series of these actions are repeated to control the duty of the load.

Abstract: PURPOSE: To make it possible to correct the swing of an image due to a hand shake, to increase the processing speed and to simplify the hardware by detecting a movement vector only of a stop image and making the correction. CONSTITUTION: The output of an image pickup element 31 is converted 32 from analog to digital into image data.
