Abstract: PURPOSE:To improve remarkably the durability of a thin magnetic metallic film by forming the thin magnetic metallic film on a substrate and subjecting the surface of the thin magnetic metallic film to an ion bombardment treatment then forming a carbon protective film on the thin magnetic metallic film. CONSTITUTION:The Al-Mg alloy substrate provided an Ni-P plaiting layer is prepd. and an underlying film consisting of a low melting point metal is formed on the plating layer to 200Angstrom  film thickness by electron beam vapor deposition under the conditions of 1X10<-5>Torr pressure and 150 deg.C substrate temp. Co is similarly formed thereon by electron beam vapor deposition under the conditions of 1X10<-5>Torr and 150 deg.C substrate temp. to form the thin magnetic metallic film to 1,000Angstrom  film thickness. The surface of the thin magnetic metallic film is subjected to the AC bombardment treatment in a bombardment chamber kept under 0.5Torr pressure. The carbon protective film is finally formed on the thin magnetic metallic film by a vacuum deposition method. The adhesive strength between the thin magnetic metallic film and the carbon protective film is thus increased and the durability of the resultant magnetic disk is remarkably improved.

Title: Driving system of image sensor
Inventor: MORIYA KAZUMASA
IPC: H04N1/04
Filed: 1982-03-30
Abstract: PURPOSE:To always give a proper amount of light to an image sensor, by varying the scanning period in response to the light volume given to the image sensor. CONSTITUTION:The gain of an amplifier 2 is previously controlled so that the saturation voltage of an image sensor is set at a constant level after the amplifier 2. The output of a peak holding circuit 4 is supplied to the terminal of one side of a comparator 5 and compared with the reference voltage. Then the scanning period is successively extended from 20ms. When the peak holding voltage level of the first scanning does not reach the reference voltage, a signal of this difference is delivered from the comparator 5 and supplied to a scanning period control circuit 7 via an A/D converter 6. The circuit 7 extens successively the scanning period until no difference output is delivered any more from the comparator 5. In such a way, several times of scanning are satisfactory for obtaining the optimum scanning period, i.e., the optimum exposure time for the image sensor.

Abstract: PROBLEM TO BE SOLVED: To miniaturize an apparatus and easily adjust the sensitivity of the apparatus, by providing magnetic plates opposed to each other at both faces of a conductive plate to cover at least part of an opening and, a magnetoelectric conversion element arranged between the magnetic plates. SOLUTION: Magnetic plates 6 are opposed to each other at both faces of a conductive plate 5 to cover at least part of an opening 7 of the conductive plate 5 opened at a lateral side part. At the same time, a magnetoelectric conversion element 3 is disposed between the magnetic plates 6 at the opening 7 of the conductive plate 5.

Since both the conductor 5 and the magnetic bodies 6 are sheet-shaped in a layered structure, the apparatus becomes considerably small. Moreover, since the magnetic plates 6 are trimmed, the amount of magnetic fluxes interlinking the element 3 can be changed, and accordingly the element 3 is easily and accurately adjusted in sensitivity.

Filed: 1979-04-27
Abstract: PURPOSE:To enhance the quality of the reproduced picture as well as minimize the increment of the price, by providing the ghost eliminating circuit which uses the charge transfer element into the TV picture receiver. CONSTITUTION:The output tap is selected via switch 5 so that the delay time at charge transfer element 1 with tap may be identical to the delay time to the direct wave of the ghost disturbance wave. And thus the input video signal is delayed by the above delay time to be supplied to amplitude/polarity control circuit 2, and then supplied to addition compounding circuit 3 with the same amplitude as the ghost signal and the inverted polarity to be added to the delayed signal. On the other hand, the color burst signal supplied through signal terminal 8 is compared with the signal sent from voltage control type crystal oscillating circuit 9 through phase detector 10. In case some phase difference exists among the signals, the error signal is obtained, and the feedback is applied to circuit 9 via phase control circuit 11. With this feedback system, the oscillating output signal of circuit 9 features the same phase as the color burst signal to obtain the same steady frequency as the color burst. Thus element 1 is driven.
