Abstract: PURPOSE:To make it unnecessary to add a circuit which is not turned on and off in a high speed, by providing an electrolyte, an electrode consisting of a transition metallic oxide, and an electrode consisting of a material having the  electric conductivity in a partially transparent and closed vessel. CONSTITUTION:An anode terminal 1 is fixed to one end face of a vessel 5 so as to be brought into cotact with an electrolyte 4 consisting of an acidic material, and a cathode terminal 2 is extended to the approximate center of the electrolyte 4 through the other end face. An electrode 3 consisting of transition metallic oxide WO3 is formed throughout the inside face of the vessel 5.

Title: Method of reproducing diffraction grating
Inventor: SUMI TAKESHI
IPC: G02B5/18
Filed: 1988-05-10
Abstract: PURPOSE:To improve diffraction efficiency by admitting a material in a monomer state onto a stamper and polymerizing the same to form a transparent linear polymer, then stripping the polymerized linear polymer from a stamper and reproducing the same as a diffraction grating. CONSTITUTION:Methyl methacrylate 2 in the monomer state is poured into an enclosure 1. Since the methyl methacrylate 2 in this state is low in viscosity, the methyl methacrylate flows deep into grooves 60 of the stamper 55. The methyl methacrylate 2 in the monomer state poured into the enclosure 1 in such a manner is thermally polymerized or photopolymerized to form e transparent liniar polymethyl methacrylate 3. The polymethyl methacrylate 3 is thereafter stripped from the stamper 55, by which the polymethyl methacrylate is reproduced as the transparent diffraction grating having the grooves 4 reversed in ruggedness from the grooves 60 of the stamper 55. Since the plastic material intrudes deep into the grooves in this case, the diffraction efficiency is enhanced even in case of small pitches.

Title: Method and device for picture encoding
Inventor: IIZUKA YOSHIO
IPC: H04N19/176
Filed: 1994-05-26
Abstract: PURPOSE:To not only achieve a prescribed compression rate but also suppress the degradation in picure quality of a reproduced picture by preliminarily setting a certain color space as a specific color and changing the encoding control in accordance with the color. CONSTITUTION:A specific color proportion measuring part 102 initializes (n) and a specific color proportion measuring counter COUNT to one and 0 respectively and takes the n-th picture element as the input and discriminates whether its color difference signals Cbn and Crn are within a determined range or not; and if they are within this range, the counter COUNT is incremented. When the processing for all picture elements in one block is not terminated by n<N, (n) is incremented; but when the processing is terminated by n=N, the value of the counter COUNT is compared with a threshold COUNTth for color difference signal Cr. A specific color proportion report signal 103 SP=1 is outputted when the specific color proportion is equal to or higher than a prescribed value, but Sp=0 is outputted when it is lower. A quantizer 104 is provided with at least two kinds of quantization tables for luminance signal Y, and the table having a shorter quantization step width is used for the block having a high specific color proportion to suppress the degradation in picture quality of the reproduced picture.

Title: Phase type strain gauge
Inventor: UMEZAWA SADAO
IPC: G01B7/16
Filed: 1984-06-04
Abstract: PURPOSE:To constitute a strain gauge of a type to be stuck to the surface of an object, so that it is not influenced essentially by a temperature variation, by measuring a phase difference of a high frequency voltage, as a physical quantity corresponding to a strain. CONSTITUTION:Electrodes 3 of four pieces each are arranged in two parts of the surface of an insulating substrate 2, and a high frequency voltage whose phase has been shifted by 90 deg. each to each adjacent electrode is impressed to these electrodes. Also, an electrode 5 is provided on two parts, too, of the surface of an insulating substrate 4, and joined at a part of a spacer 17 so as to be opposed to the electrode 3. The substrate 2 is stuck to an object to be measured 1, and expands and contracts by following its expansion and contraction. According to this constitution, when a voltage is impressed to the electrode 3, a voltage of the same frequency is induced in the electrode 5 and an output electrode 13. A phase of the voltage of the electrode 13 becomes a function of a relative position of the electrodes 3, 5, but a phase decomposition can be executed comparatively easily. The expansion and contraction caused by a load, etc. of the object to be measured 1 generates a relative displacement which is equal to the expansion and contraction of the object to be measured 1 between the electrodes 3, 5, but as for a temperature variation, the relative displacement is not generated by using the substrates 2, 4 which is very small, and whose coefficient of thermal expansion is nearlyh equal to that of the object to be measured 1.
