Abstract: PURPOSE:To enable the impartation of light resistance to the device by forming a cell by using substrates, at least one of which have layers for suppressing the transmission of short wavelength UV rays. CONSTITUTION:A light control layer forming material contg. a liquid crystal material, polymerizable compsn. and polymn. initiator is interposed into an empty cell consisting of two sheets of the, substrates, at least one of which have electrode layers and is irradiated with active rays to polymerize the polymn. compsn., by which the three-dimensional network structure consisting of the transparent high-polymer material is formed in the continuous layer of the liquid crystal material. A coating material which suppresses the transmission of the short wavelength UV rays is applied on the surfaces opposite from the ITO treated surfaces of the substrates with the electrodes and is then dried by heating, by which coating films for suppressing the transmission of the UV is formed. Otherwise, the thermoplastic coating films, such as polyvinyl butyral for suppressing the transmission of the short wavelengths are inserted between the opposite surfaces of the ITO treated surfaces of the substrates and the glass plates and are welded with heat and pressure. Such films are used as the sandwich glass for suppressing the transmission of the UV rays.

Inventor: IAI SATORU
IPC: H04N9/00
Filed: 1992-12-24
Abstract: PURPOSE:To select a high definition picture in which high quality (sharpness, pleasantness and powerfullness) is psychologically strongly impressed by using a physical characteristic quantity contributing to the high quality as an index. CONSTITUTION:An RGB signal of plural kinds of pictures is sequentially inputted from terminals 101-103 and a relevant picture number is inputted from a terminal 11. A converter 12 converts each RGB signal into an HVC signal. Computing elements 13, 14, 15 obtain a variance of H signal distribution in each HVC signal (corresponding to powerfulness), an autocorrelation coefficient of V signal in each HVC signal (corresponding to pleasantness) and a variance of C signal distribution in each HVC signal (corresponding to sharpness) and store them in memories 16, 17, 18 together with the picture number. When the processing of each picture is finished, selectors 19, 20, 21 select a picture number of a maximum value. As a result, the number of a picture provided with a psychological factor with highest quality is outputted from terminals 22-24.

IPC: B24C3/00
Filed: 1992-12-25
Abstract: PURPOSE:To remove flaws generated on the inner and outer surfaces without impairing the surface unevenness on the outer surface and enable re-use by furnishing a chamber where the panel of a cathode-ray tube or its component panel and a spouting part are arranged, and thereby preventing sputter of the polish solution spouted out of the spouting part. CONSTITUTION:A panel flaw repairing device for a cathode-ray tube 27 is fundamentally composed of a chamber 20, holding part 21, spouting part 22, and a polish solution supplying part, wherein a nozzle 26 is arranged confronting a panel 1 inserted in the chamber 20 from a hole provided in one of its side walls, and the polish solution is at a high speed spouted to the flaw part of the panel 1 from this nozzle 26. Accordingly the spouted polish solution runs against the panel 1 on its front, and acute corners of the flaws are abraded in priority to the other parts. Because the polish solution runs against the panel 1 on its front, fine unevenness on the outer surface of the panel 1 does not hinder collision of the solution. Further, the contaminant attached strongly to inside of recesses can be beaten out effectively.

Filed: 1992-12-25
Abstract: PURPOSE:To easily measure the distance between the sample surface and a piezoelectric element by changing the cantilever type piezoelectric element at its natural frequency, and changing the admittance of the piezoelectric element. CONSTITUTION:A cantilever type piezoelectric element 1 formed with a Si substrate 2 and a sample 7 are arranged, and the element 1 is fixed to another expanding piezoelectric element 3. The bimorph type element 1 is driven by an AC power source 5 to make bending movement. The admittance of the element 1 can be measured by a voltmeter 6. The distance between the element 3 and the element 1 can be controlled by a variable DC power source 4. When voltage is applied to the element 3 from the power source 4 and the tip of the element 1 is brought into contact with the sample 7, the natural frequency is changed, and the admittance is changed. The element 3 is adjusted so that the element 1 is kept in no contact with the surface of the sample 7, then the bending movement of the piezoelectric element 1 is performed at the natural frequency by the power source 5. If the applied voltage when the element 1 is brought into contact with the sample 7 and the displacement quantity at the natural frequency are found, the distance between the stationary point at the tip of the element 1 and the surface of the sample 7 can be measured.

Title: Device for deciding color compensation parameter
Inventor: MATATSUMA MITSUAKI
IPC: G03F3/08
Filed: 1991-12-27
Abstract: PURPOSE:To decide an optimum color compensation parameter which converts a luminance signal RGB which is obtained from a scanner into the main density signal CMY of ink in a color printer. CONSTITUTION:RGB is read as against plural colors indicated by CMY. In the meantime, CMY is converted into RoGoBo (the luminance signal of three primary colors) by reverse non-linear transformation by the storage value of a non-linear parameter storing means 4. A color compensation coefficient is calculated from RGB and RoGoBo and it is stored in a color compensation coefficient storing means 7. The RGB is masking-operated by the calculated color compensation coefficient and non-linearly transformed by the storage value of the non-linear parameter storing means 4, further, converted into C'M'Y'. An evaluation value which indicates the difference of the colors between CMY and C'M'Y is calculated by an evaluation value calculating means 10. A control means 11 keeps updating the parameter of the color conversion parameter storing means 4 till the evaluation value is minimized. When the evaluation value is minimized, the storage values of the color compensation coefficient storing means 7 and the non-linear transform parameter storing means 4 are decided.
