Title: Switching power-supply circuit
Inventor: HORIO KENJI
IPC: H03K17/16
Filed: 1993-10-28
Abstract: PURPOSE:To reduce a loss in switching and noises of a FET in a switching power supply circuit. CONSTITUTION:A voltage at a drive winding (LD) is provided to a base of a transistor Q2 through an integration circuit made up of a resistor 5 and a capacitor C3. The voltage applied to the base of the transistor Q2 increases according to a time constant of the integration circuit, and while a degree of continuity of the FET increases gradually, the drain voltage decreases gradually. As a result, a current discharged from a capacitor C4 is not so abrupt as a conventional one and the current is discharged after the drain voltage is lowered. Then, a duplicated waveform of drain current and drain voltage can be reduced to a minimum, and thereby a switching loss can be reduced. In addition, a snubber circuit may be formed in a main switching transistor so that the linking of output drain voltages or a discharged current at switch-on time can be reduced.

Abstract: PURPOSE:To realize positioning corresponding to recognition precision by obtaining the relative positional relation of a moving body and an objective body from a shadow by the shape of the objective body, the shadow of a projection pattern obstructed by the moving body, and the shadow of reflected light from the objective body obstructed by the moving body. CONSTITUTION:An image processing means 14 obtains the relative positional relation of the moving body 3 and the objective body 8 on the basis of position information obtained by recognizing the shadow formed from the shape of the objective body 8, the shadow formed because the pattern projected toward the objective body 8 from a light source 4 is obstructed by the moving body 3, and the shadow formed because the reflected light from the objective body 8 is obstructed by the moving body 3. Accordingly, the relative positional relation of the moving body 3 and the objective body 8 can be obtained through the camera input image processing of one time, and the moving direction and the movement of a moving mechanism can be determined from the relative positional relation. Thus, the positioning not based on teached precision but corresponding to the recognition precision can be realized.

Abstract: PURPOSE:To shorten the length in thrust direction to attain a smaller size and an improvement in precision by arranging the longitudinal direction of the magnetic field detecting part of a magnetic sensor at a right angle to the tangential direction in the nearest part to a magnetic drum, and arranging the width direction of the magnetic field detecting part of the magnetic sensor in parallel to the magnetizing direction of the magnetic drum. CONSTITUTION:Magnetic patterns 22, 23 of a magnetic drum 2 are magnetized by a ring head, and random patterns and incremental patterns with equal intervals are written in the arrowed direction in the fiqure. A magnetic sensor 3 consists of a sensor base 31 and a magneto-resistance effect (MR) element 32, and a magnetic field detecting part is arranged so that its longitudinal direction is nearly right-angled to the tangent of the drum surface in the nearest part to the magnetic drum 2, and the width direction is in parallel to the magnetizing direction of the drum 2. An arithmetic processing circuit 4 conducts the arithmetic processing of an electric signal which detects a resistance change based on the change of magnetic flux. Since a bit pattern signal regulated in position by the MR element 32 is detected when the magnetic drum 2 is rotated by bit number times corresponding to resolution, it is collated with a preliminarily stored position pattern data to detect the absolute position.

Title: Flow rate display for comparing and deciding frequency of measuring pulse train signal and set threshold frequency
Inventor: KONDO NOBUAKI
IPC: G01F15/00
Filed: 1985-12-04
Abstract: PURPOSE:To enable the decision of higher frequency between two frequencies by resetting a pulse generator by measuring pulse train signals every pulse thereof and comparing the frequency of set pulse train signals after a resetting and the frequency of the measuring pulse train signals. CONSTITUTION:First, a pulse generator to which a desired frequency can be set is prepared. Then, measuring pulse train signals are passed through a differentiating circuit and a clipping circuit to produce differential wave pulses which are inputted to the resetting circuit in the pulse generator and reset the pulse generator by the pulses of the resetting circuit. The output pulse train signals of the pulse generator and the measuring pulse train signals are inputted to a frequency comparing circuit both in the form of differential wave pulses. Since the pulse generator is already reset by the measuring pulse train signals, the output pulse train signals themselves involve the comparison information of a measuring frequency and a set frequency. Utilizing also the comparison information, the frequency comparing circuit compares and decides the measuring frequency and the set frequency and outputs measured values in the form of ON and OFF.
