Title: Optical filter
Inventor: SHIMADA TOSHIYUKI
IPC: G02F1/01
Filed: 1990-08-02
Abstract: PURPOSE:To form a high-speed filter by using an optical recording medium which provides wavelength selectivity based upon a multiple photon and electron mobility process and causes a reversible change in transmission characteristic corresponding to an applied electric field. CONSTITUTION:The medium which has an irregular spread of its absorption spectrum is cooled to extremely low temperature and irradiated with laser light which is extremely narrow in wavelength width in the absorption band of an electron donors 1, and then the medium is excited selectively by only donors which resonate with the irradiation laser light, so that some of them give electrons to electron receptors 2. Consequently, the absorptivity of only the wavelength of the laser light irradiation decreases after the laser irradiation and holes are formed in the absorption bands of the donors. Consequently, plural band-pass optical filters which have an extremely narrow transmission band are formed in dimensions of the wavelength. Further, the filter formation is based upon electron mobility reaction, so the high-speed filter is formed. The variation of the transmission characteristics of the filter and the erasure of the filter can be performed by applying an electric field to the medium.

Title: Control circuit of amount of exposure
Inventor: NISHIWAKI YOSHIKAZU
IPC: B23K26/06
Filed: 1982-11-20
Abstract: PURPOSE:To hold the amount of exposure invariably constant by measuring and integrating the intensity of laser light all the time and ending an exposure process when the integral value attains to a specific value. CONSTITUTION:The rear mirror of a laser 1 has finite transmittivity and a part of laser light from the rear mirror is projected. The intensity of the projected light is detected by a photodiode 7 and amplified by an amplifier 8, which outputs a voltage Va. The output of the amplifier 8 is integrated by an integrator 9. The output Vb of the integrator 9 is proportional to the integral value of the laser light intensity, so the output Vb is also proportional to the intensity of laser light incident to photoresist 6. The output of the integrator corresponding to the desired amount of exposure is denoted as Vc. A comparator 10 compares a reference voltage Vc with the output Vb of the integrator 9 to open and close a shutter. Thus, the amount of exposure is held invariably constant.

Title: Photomagnetic disk and its production
Inventor: HARA NORIAKI
IPC: G11B11/105
Filed: 1982-11-19
Abstract: PURPOSE:To obtain a photomagnetic disk with which a magnetic thin film is easily oriented vertically with a reduced degree of oxidation and a small change with time, by separating a substrate made of a glass plate having a low melting point provided with tracking grooves from a stamper and then forming a magnetic thin film on the side surface of the tracking groove of said substrate. CONSTITUTION:A disk forming oven 14 is heated previously up to 450 deg.C and then cooled slowly after the surface of the molten glass poured into a stamper 11. Then the stamper 11 made of polyimide resin is separated after the oven 14 is completely cooled. Otherwise a solvent such as 2-aminoethanol is used to dissolve the polyimide resin. Thus a glass substrate is obtained. In this case, the surface of the glass substrate is polished flatly because the impurities like an oxide, etc. remain there. Thus a glass substrate 24 having a tracking groove 23 is obtained as shown in the figure. Then a metallic material such as rare earth or iron, etc. is formed on the side surface of the groove 23 as a magnetic thin film 26 by a vacuum vapor deposition process, a sputtering process, etc.

IPC: H04N1/32
Filed: 1992-07-31
Abstract: PURPOSE:To provide an image communication equipment at the low cost to receive and record an accurate answer to a Q command. CONSTITUTION:Received coded data are decoded by a decoding means 5a for each prescribed quantity, and the transmission errors are checked for each line based on these decoded data.

Title: Method for treating degassing in molten steel
Inventor: YAMAMOTO TAKAIKU
IPC: C21C5/46
Filed: 1988-08-18
Abstract: PURPOSE:To effectively execute degassing and decarbonization in molten steel by arranging a gas blowing nozzle in a long nozzle at the time of tapping the molten steel into a ladle under reduced pressure atmosphere from a steelmaking furnace through the long nozzle. CONSTITUTION:The air in the ladle 1 is exhausted through an exhaust hole 3, and after making reduced pressure in the ladle 1, the molten steel 9 in the steelmaking furnace 5 is tapped into the ladle 1 through a tapping hole 6 and the long nozzle 7. At the same time, gas is blown into the molten steel flow flowing in the long nozzle 7 from the blowing nozzle 8 arranged on the long nozzle 7. By this method, a reaction interface area ratio A/V of the molten steel stream (A: gas-metal interface area, V: drip volume) is increased to execute the degassing at high efficiency. Therefore, in the case of decarbonization, the oxygen source is charged from an oxygen source supplying hole 4. By this method, the erosion of the steel tapping hole refractory is prevented and the service life thereof is extended.

Patent JP-S6257377-A (JP)
Title: Sample data processor
Inventor: CHRISTOPHER TODD J
IPC: H04N5/45
Filed: 1986-09-02
Abstract: System performance of picture-in-picture video display systems is dependent on critical timing relationships between the incoming signals and the clock signals used to sample and display both the large picture and small picture signals. Video signals from various sources, e.g. VTR's, tend to have jittering time bases which may cause the small image to appear jagged or tilted. This distortion in the small image may be reduced by effecting adaptive signal delays in the small picture signal responsive to the relative phase of the system clock signal with respect to the horizontal synchronizing pulses of the large and/or small picture signal. One phase measure is used to control an interpolator which combines successive samples of the small picture signal in proportions to develop sample values corresponding to samples that would have occurred had the small picture signal been sampled by a clock properly aligned to the small picture horizontal synchronizing pulses. A second phase measure is used to delay the clock signal used to display the small picture so that the clock pulses that define the edges of the small picture occurs with the same timing relative to the large picture horizontal synchronizing pulses form line-to-line.
