Title: Earthing resistance lowering sheet
Inventor: YOSHIDA AKIRA
IPC: H01R4/66
Filed: 1990-05-10
Abstract: PURPOSE:To improve workability and attain good conductivity for a long duration by covering the surface layer of a sheet-like carbon fiber with a highly waterabsorptive resin mixed with carbon fiber chops. CONSTITUTION:The surface layer of a sheet-like carbon fiber 1 is covered with a highly water-absorptive resin 3 mixed with carbon fiber chops 2 and a conductive layer in which an earthing pole 6 is fixed is formed by sticking and fixing the carbon fiber sheet using a conductive paint 5. Consequently, the sheet absorbs water by giving water when the sheet is buried in ground and releases water owing to evaporation of water underground. Also, the carbon fiber chops 2 are ones which do not lower the conductivity and maintain their functions almost permanently. As a result, good conductivity is maintained for a long duration even in the place where a fixed resistance is high.

Abstract: PURPOSE:To reproduce a thin line in an excellent way by applying resolution correction in the pre-stage of multilevel processing in applying multilevel processing after color separation. CONSTITUTION:Means 15A, 15B converting color picture information into plural color signals through the separation of plural color separation images, a color separation means 35 separating a chrominance signal in plural bits further to the color signal, a resolution correction means 450 to the chrominance signals to be separated in plural bits and a means 600B for applying multilevel processing to the picture signal whose resolution is corrected, are provided. In applying multilevel processing to the picture information after color separation, the multivalue processing is executed based on the picture information whose resolution is corrected. Thus, the contour of the picture is emphasized and the deterioration in the picture is less even with multilevel processing and since the contour of the picture is made clear, the setting width of the multilevel threshold value is widened remarkably more than the multilevel processing before the resolution correction.

Abstract: PURPOSE:To mass-produce extra-micro rollers of the same diameter by bundling the glass cores  which are hard to dissolve with acids and have been coated with the glass layers which are soluble with acids, and have a low softening point and viscosity temperature and approximate coefficients of expansion, stretching the same under heating and acid-eluting the coating layers. CONSTITUTION:Glass cores 1 of about 10mm. diameter which are rollers used for spacers for manufacturing liquid crystal cell cases and are hard to dissolve with acids are put in glass cylinders of about 14mm. outside diameter and about 11mm. inside diameter which are lower in softening point and viscosity than said cores, have approxiamate coefficients of expansion and are soluble with acids. Further, a multiplicity of these are put concentrically into a glass cylinder 4 of the same quality as that of the glass cylinders 2. This is then heated to about 780 deg.C and is thus melt stuck. This is next put into a glass cylinder 5 of the same quality as that of the multiple glass cylinders 2 and while the inside of the glass cylinder 5 is being maintained in a vacuum, it is passed through a furnace 8 maintained at about 800 deg.C by an annular heating element 7 and is stretched to about 2mm. diameter by rollers 10. After this is disintegrated on a pad, the broken pieces are immersed for about 1hr in about 1.5N nitric acid soln. to elute the acid-soluble glass base, whereby the desired rollers of a length about 3 times the diameter are obtained.

Filed: 1984-06-14
Abstract: PURPOSE:To reduce the bodytube of a lens at its size and weight and to improve dulability and optical performance by making a focus ring and a fixed tube of synthetic resin and forming coating films having low frictional factor and wear proof on respective helicoid screw parts of the focus ring and the fixed tube. CONSTITUTION:When the focus ring 1 and the fixed tube 2 are made of synthetic resin, the size of respective helicoid screw parts 1a, 2a is dispersed in accordance with molding conditions. Therefore, the focus ring 1 and the fixed tube 2 are molded so that a gap preventing maneuverability at a screwing time from being deteriorated due to tight screwing of the focus ring 1 and the fixed tube 2 is formed. Thereby, the dispersion of the size of the helicoid screw parts 1a, 2a is absorbed by forming the coating films 12a1, 12a2 consisting of molybdenum bisulfide to set up a screwing play variable 11a1 within an allowable value as a lens barrel. Thus, the lens barrel can be reduced in size and weight and its dulability and optical property can be improved.
