Title: Carrier wave regeneration device
Inventor: MAENO TETSUROU
IPC: H04L27/06
Filed: 1979-04-17
Abstract: PURPOSE:To obtain a carrier wave regeneration device which is free from a phase jitter and simple in its circuit configuration, by compering phase of an output of the voltage control oscillator VCO and a carrier wave which has been extracted from a received signal, and controlling the aforesaid VCO by its compared output. CONSTITUTION:A facsimile signal by 100% modulation system of AM-PM-VSB system is applied through the AGC circuit 1 to BPF2 which makes a carrier wave frequency its center frequency. The frequency which has been extracted is made frequency of two times by the step-up multiplier 3, and is shaped to a square wave through BPF4, the limiter 5 and the comparator 6. This square wave and the output of VCO10 are subjected to phase comparison by the phase comparator 7, its output is made a DC level signal through the integrator 8, and the low pass filter LPF9, and controls VCO10. The output of VCO10 is made frequency of 1/2 by the frequency divider 12 after it has been subjected to phase correction, and it is utilized as a regenerated carrier wave.

Title: Optical information recording and reproducing device
Inventor: YAMAMIYA KUNIO
IPC: G11B7/085
Filed: 1985-03-11
Abstract: PURPOSE:To shorten considerably the seek time for access by arranging an external scale near the center of gravity of a moving body to minimize the read error of the external scale. CONSTITUTION:An external scale 17 is attached to a device body frame 1 vertically across the center part of a housing 6. The external scale 17 is extended in the going direction of a carriage assembly 4 and passes a center A of gravity of the carriage assembly 4. Even if somewhat oscillation occurs, the read error of the external scale 17 is hardly generated. That is, the oscillation occurs with the center A of gravity of the carriage assembly 4 as the center, and the oscillation amplitude is very small near the center A of gravity. Since the center of gravity where the amplitude is small coincides with the set position of the external scale 17, instrumentation is performed without being affected by the oscillation.

Title: Detecting circuit for ac current
Inventor: OKAMATSU SHIGETOSHI
IPC: G01R19/22
Filed: 1978-04-24
Abstract: PURPOSE: To make it possible to reliably detect the current of variable low frequency to be detected, while reducing the cost, by constructing the detecting circuit for an AC current of an AC transformer, a rectifier and a DC transformer.  
     CONSTITUTION: The output of an AC transformer 1 to be connected with a conductor through which the current to be detected flows is fed to a rectifier 2 so that it is converted into a DC current. A load resistor 3 is not connected with the DC side output circuit of the rectifier 2 so that the current of the DC side output circuit of the rectifier 2 is detected by a DC transformer 4. The DC transformer 4 is connected with an AC constant voltage power source 6 so that the output composed of the output of the DC transformer 4 is made to flow by a diode 5 to the load resistor 3 thereby to detect the output corresponding to the current to be detected. As a result, the iron core of the transformer 1 is hardly saturated but the low frequency current is easily detected. Since, moreover, the power source 6 is an AC power source, the mounting can be facilitated so that the output voltage can be raised.

Filed: 1989-02-28
Abstract: PURPOSE: To make the spatial distribution of ultrasonic waves visible and to inspect ultrasonic transducer easily and swiftly by receiving the ultrasonic wave with two-dimensional matrix-like detectors, and displaying it in the form of a picture image formed by picture elements corresponding to individual detectors. CONSTITUTION: An ultrasonic transducer 10 is fitted to one surface 12a of a transmitting block, and to.the other surface 12b a detector matrix 18 is fitted. The output amplitude of each detector is outputted to a display 60 through a receiving means 16 and a processing means 40.
