Title: Noise detecting circuit
Inventor: SUGAI YOSHIROU
IPC: H04B1/10
Filed: 1981-06-09
Abstract: PURPOSE:To realize the quick processing of the noise which is instantaneously produced for a noise detecting circuit of an FM signal receiver and fetching a noise signal of a high frequency from HPF in the noise cancel circuit to give a D/C conversion to the noise signal. CONSTITUTION:An automatic gain control amplifier 9 processes quickly the noise signal delivered from an HPF4 and accordingly supplies an output to monostable multivibrator circuit 10 to trigger it. The triggered circuit 10 transmits a pulse of a narrow duration and gives an open control to a gate circuit 11. Thus the circuit 11 fetches the noise detected by an HPF4 and supplies the noise signal to a D/C converting circuit 15 via a level holding circuit 12, an LPF 13 and an amplifier 14. As a result, a control signal of a DC level corresponding to the detected noise is obtained from the circuit 15.

Title: Laser scanning optical system device
Inventor: ENOMOTO JIYUNICHI
IPC: H04N1/23
Filed: 1984-05-02
Abstract: PURPOSE:To compensate properly a scanning shift by continuously detecting the positional shift of a laser beam during the period of scanning and adjusting the carrier frequency of an optical modulator on the basis of the detected result. CONSTITUTION:The diffraction angle 2theta of a diffracted light B1 of laser light B from non-diffracted light B0 is expressed as 2theta lambda.f/v on the basis of the wavelength lambda of light, the ultrasonic wave speed (v) of an acoustic/optical medium and carrier frequency (f). When there is no surface inclination in a polyhedral mirror 5, laser light B1 scans the surface of dots 7a of a laser scanning position detector 7 at the time of frequency f=fa. When the irradiation of the laser light B1 upon dots 7alpha+i of the detector 7 is detected because of surface inclination, the carrier frequency is adjusted to f=fa+i so as to be compensated by the positional shift of the dots. Consequently, a regular scanning position can be scanned at a beam irradiation starting position 81 on a drum.

Abstract: PROBLEM TO BE SOLVED: To execute a cleaning treatment of the surface of a cutlery tool member without deteriorating the characteristics of a blade part by mechanically grinding the flat surface part of the blade part and the tool and subjecting the surface part to a vacuum arc descaling. SOLUTION: The plane surface part of the cutlery tool 1 is mechanically ground by a grinder, etc. Cup-shaped vacuum vessels 7, 7' are mounted at the part desired to be descaled of the cutlery tool 1 and only the local part is evacuated.

The cathode points are not formed on the mechanically ground surface before the scale removal is completed and, therefore, the blade part is not thermally affected by the cathode point effect. The holding voltage of the arc attains a high value and the completion of the scale removal is detected when the cathode points are formed on the material surface.
