Title: Picture signal band compression system
Inventor: ASHIBE MINORU
IPC: H04N7/12
Filed: 1988-04-06
Abstract: PURPOSE:To reduce deterioration in picture quality due to complicated combination of limited kinds of modes with a larger picture quality difference among adjacent blocks in spatial or timewise directions by applying filtering to the mode decided once in the spatial or timewise directions so as to correct the mode. CONSTITUTION:An interpolation error to each mode is calculated and the total sum in a block of the absolute value of the interpolation error, for example, is calculated by using the said error and the result is used as a distortion for each block. Then the mode is decided by using the distortion for each block. After the determination in this way, filtering is applied to the mode decided once in the spatial or timewise direction to correct the mode. Thus, the possibility of the assignment of the same mode in the spatial or timewise direction is enhanced. Then the deterioration in picture quality due to a random change of the mode in the timewise direction caused by noise depending on complicated combination of limited kinds of modes with a larger picture quality difference for each block timewise directions is reduced.

Filed: 1979-07-02
Abstract: PURPOSE:To simply constitute the system transmission system, by the light emitting section which can change the wave length emitted, and the optical filter which can pick up the light of specific wave length only from the transmission line. CONSTITUTION:The signal light from the light emission section 1 which can change the wave length emitted is transmitted to either one of the photodetection sections 2, 3, or 4 through the optical fibers 5, 6, 7, 8, 12, 13, 14 and the optical filters 9, 10, 11. For example, in case of transmission to the photodetection section 3, the  wave length of light emission of the light emission section 1 is made in agreement  with the wave length lambda2 of the optical filter 10, allowing to pass the light in the  filter 9 without loss and to transmit the signal only to the photodetection section 3. Accordingly, since the opposing party can be switched and selected by changing the  wave length of the light emission section only, the transmission system can simply  be constituted.

IPC: G03B13/36
Filed: 1988-04-05
Abstract: PURPOSE:To eliminate space for disposing a metering sensor and to prevent the loss of light quantity by providing a metering transparent sensor inside or neat a lens mirror barrel. CONSTITUTION:The transparent metering sensor, that is, the transparent sensor 24, is disposed close to and after the diaphragm 23 of a photographing lens 1 in the lens mirror barrel 22. The outside diameter of the transparent sensor 24 is roughly identical to an aperture D0 when the diaphragm 23 is opened. As a result, the quantity of light made incident on the transparent sensor 24 corresponds with the brightness of an object. The diaphragm 23 is narrowed down in photographing, and in that state the object is metered by the transparent sensor 24. Namely, real time metering is carried out. Thus, the need of space for disposing the metering sensor is eliminated to prevent the loss of light quantity.

Abstract: PURPOSE:To simplify the constitution and to estimate accurate key stroke strength by estimating a string striking speed corresponding to a key speed found by a key speed detecting means and updating the latest value as a real estimated string striking speed when the estimated string striking speed which is calculated successively is larger than a last calculation result. CONSTITUTION:When the depression position of a key of the automatic playing piano 1 is one of reference positions, a position detecting means 2 generates a detection signal and a key speed detecting means 3 finds the key speed from intervals of time when the detection signal is generated successively. Further, a storage means 4 is stored previously with the relation between key speeds and string striking speeds and when a key speed is found, an estimated string striking speed calculating means 5 finds the estimated string striking speed corresponding to the key speed. Then an update means 6 updates the latest found value as the real estimated striking speed when the latest found value is larger than the last value. Consequently, a sensor is provided only on the key side to simplify the constitution and the accurate key stroke strength can be estimated corresponding to variation in key depressing speed.

Title: Electric double-layer capacitor and manufacture thereof
Inventor: KURABAYASHI KEN
IPC: H01G11/42
Filed: 1990-03-30
Abstract: PURPOSE:To decrease internal resistance by bringing a current collector comprising a conductive material, wherein fine conductive particles are mixed into a base material, into contact with a specified surface of a porous electrode body comprising fine sintered carbon particles, attaching the current collector to the surface, and inserting a part of the current collector into the hole part of the porous electrode body a while contacting therewith. CONSTITUTION:As an electrode 1, a porous plate-shaped electrode body is formed by baking or sintering the particles of active carbon as a raw material. The electrode body is impregnated with a specified electrolyte. Since the raw materials are bonded together, the internal resistance exhibits a low value. Since the porous raw material is used, a large area is provided. As a current collector 2, conductive unvulcanized rubber is brought into contact with the electrode body. Heat curing is performed, and the rubber is brought into close contact with the electrode body. Therefore, the conductive rubber flows into the inner parts of the porous hole parts. The contact area between the electrode body and the current collector 2 becomes large. Thus the electric contact resistance becomes small. In this way, a capacitor characterized by the large capacitance and the lower internal resistance can be obtained.
