Patent JP-S62221718-A (JP)
Title: Resetting circuit
Inventor: KANEDA HIROYUKI
IPC: H03K17/22
Filed: 1986-03-20
Abstract: PURPOSE:To prevent the abnormal operation of a system as a whole when the multi-connection is applied with an electronic device, releasing the overall resetting function of the system with no time delay after a fixed period of time in an ON mode of power supply and then validating the resetting function before the drop of voltage that causes a system malfunction in an OFF mode of power supply. CONSTITUTION:The 1st comparator compares the output of a CR time constant circuit 1 which sets the initial resetting time with the 1st reference voltage 31. While the 2nd comparator 5 compares the output of a voltage monitor circuit which monitors the power supply voltage with the 2nd reference voltage 32. The outputs of both comparators 4 and 5 are supplied to the bases of the 1st and 2nd transistors TR61 and 62 which are connected in series to form a reset signal driving circuit 6. Thus the reset signal is obtained by securing an AND between both TR61 and 62. In such a way, the abnormal operation of an electronic device is avoided in the ON and/or OFf mode of power supply or in a hit mode of power supply.

Title: Peak value detector
Inventor: NAKAMURA KENJI
IPC: G01R19/32
Filed: 1978-05-24
Abstract: PURPOSE: To detect accurate peak values and obtain binary coded signals even when voltage fluctuations occur owing to temperature drift in a TV camera by obtaining a mean value from the peak values of the video signal and comparing the same with the video signal of one scanning after.  
     CONSTITUTION: Video signal Vi is applied to analog switches AS 6, 8 via amplifiers L, M, N, P. The AS 6 goes ON while a detecting circuit including an amplifier Q is detecting maximum value and the AS 8 goes ON while the detecting circuit including an amplifier R is detecting minimum value. The ASs 7, 9 go ON at the start of scanning. This yields the maximum value output VQ and minimum value output VR and addition S of both outputs yields a mean value voltage VS, which is then supplied to an amplifier T as a capacitor C 7  is charged by As 10. The mean value voltage VT obtained from the peak values of the video signal is compared U with the video signal VL of one scanning after, whereby a binary coded output VO is obtained.

Title: Method and apparatus for reducing blooming in ccd image sensor output
Inventor: JIYOOJI MAIKERU BURASUZUJINSUK
IPC: H04N5/372
Filed: 1994-03-30
Abstract: PURPOSE: To reduce blooming at the output of a CCD image sensor by toggling at least two phases of a CCD after exposing a charge-coupled device(CCD). CONSTITUTION: A CCD has three phases 10-14 formed by three gate structures, and the phases 10-14 are separately controlled by corresponding signals V1 , V2 , and V3 . Then, a charge is generated at a CCD image sensor during exposure. A transition charge for inducing blooming can be generated unless it is reduced by some methods at an area with an increased strength. Therefore, to prevent blooming, the signals V1 and V2 are toggled during scattering period after flash exposure. The scattering period should last for the amount of time for preventing the charge remaining after the toggling from generating blooming, thus reducing blooming.

Title: Video signal reproducing device
Inventor: SHIMOTASHIRO MASAFUMI
IPC: H04N9/89
Filed: 1985-03-26
Abstract: PURPOSE:To improve the recording efficiency of a recording medium and line bit density effectively by correcting the time base variation of a signal that is transferred by a frequency modulation transmission band and of a signal that is transferred by a low-pass variation transmission band. CONSTITUTION:At a counter circuit 7, the write clock pulse and the switching control pulse of a charge coupled element 5 are generated from a PLL circuit 6 by setting the output of it as a clock pulse and are outputted to the charge coupled element 5. A demodulation signal that is demodulated at a demodulation circuit 3 is outputted from the charge coupled element 5 changing to a signal without a time base variation because the demodulation signal is stored according to the time base variation and is read out according to a reference clock pulse. On the other hand, the signal of a low-pass variation transmission band that transits a low-pass filter is outputted as the high frequency component of a video signal that includes the component of original chrominance signal and at a charge coupled element 16, by the same time base collector operation, the time base variation of the high frequency component of the video signal is eliminated. By an addition at an adder 20, the time base variation is not included and the luminance signal does not become as an interference signal and a useful video signal is obtained.

Title: Manufacture of superconductor
Inventor: TAMURA YASUTAKA
IPC: C01G1/00
Filed: 1988-03-15
Abstract: PURPOSE:To oxidize the thin-film of a superconductor at a low temperature without being damaged by an ion bombardment by oxidizing the thin-film in oxygen gas containing ozone. CONSTITUTION:The temperature of a sample base 2 is controlled at a fixed value by conducting a heater 4, oxygen gas is ozonized by an ozone generator 5, and oxygen gas including the ozone is introduced into an airtight vessel 1. A superconductor thin-film 3 is oxidized in an oxidizing gas containing ozone at that time. Consequently, since the thin-film is oxidized in oxygen gas comprising ozone, the thin-film can be oxidized at a low temperature, and is not subject to a thermal adverse effect, and the method can be applied to an integrated circuit, etc. Since plasma treatment is not used, damage to the surface by an ion bombardment is almost removed, and a change with time after oxidation treatment is difficult to be generated, thus improving superconductor characteristics.

Title: Master disk cutting device
Inventor: TAKETOMI YOSHINAO
IPC: G11B3/00
Filed: 1983-04-08
Abstract: PURPOSE:To form a uniform track groove and an address signal pit with no effect given by aging of a piezoelectric element due to the continuous impression of voltage by decreasing the cutting degree of a cutting tool to the extension of the piezoelectric element. CONSTITUTION:A cutting tool attachment surface 15 is formed so as to obtain the positive inner product between the external normal line vector of the surface 15 and the external normal line vector of the surface of a master disk. A cutting tool 8 is joined to the surface 15 via a piezoelectric element 9 and shifted in parallel in response to the extension of the element 9. Thus the cutting degree changes. The surface 12 of the master disk is cut with the prescribed depth and with no voltage impressed to an electrode 10. Thus the groove processing is started. At this stage of processing, the element 9 has no extension and therefore a groove of uniform depth is formed with no effect of aging. The element 9 is extended when the voltage is impressed to the electrode 10 with signal input. Then the tool 8 is pushed to a cutting tool feed stage 11 and shifted in parallel in the direction where it gets away from the master disk. This means a reduction of the cutting degree, and a signal pit 14 is formed on the groove bottom surface 13.
