Title: Intermediate tone picture data display system
Inventor: INABA TOMOKO
IPC: G06T3/40
Filed: 1990-04-03
Abstract: PURPOSE:To express a detailed picture simultatingly on a screen by deciding the density depending on the arrangement of black and white levels of each set resulting from dividing an original picture data into some picture elements and using gradation to express the picture on the screen. CONSTITUTION:A binary picture data is divided into picture element blocks in the unit of plural picture elements adjacent to each other; the divided picture element blocks are compared with a table of gradation data weighted for the arrangement of black or white picture elements in the picture element block, the gradation of the picture element block is decided from the result and the decided gradation is displayed as one picture element on the display means. Thus, the picture elements of the original data are used for display picture element of plural number and the display picture elements are expressed by using the gradation in this way, then the original binary generating data is expressed as an intermediate tone picture on a display device and since gradation is used on the display device with rough picture element density, a detailed binary picture is simultatingly displayed.

Filed: 1990-04-04
Abstract: PURPOSE:To obtain the unidirectional mode converter and an optical isolator which uses it by forming a specular surface in a waveguide and changing the traveling direction of incident light, and combining its phase shift by reflection with mode conversion in a reciprocal and a nonreciprocal area before and after the reflection. CONSTITUTION:The specular surface 7 for Fresnel reflection is formed in the waveguide 2 and a 1st area for nonreciprocal mode conversion by magnetooptical effect is formed from the incidence end surface 3 for the waveguide light to the specular mirror 7 while a 2nd area for reciprocal mode conversion is formed from the specular surface 7 to an irradiation end surface 4 for the waveguide light. Namely, the specular surface 7 of the waveguide 2 changes the traveling direction of the waveguide light and then a unidirectional mode wherein nonreciprocal effect and reciprocal effect are caused is entered even if the magnetism in the waveguide 2 is in the same direction. Further, mode selectors 5 and 6 or polarizers are combined to constitute the optical isolator and only necessary light is allowed to pass. Consequently, the unidirectional mode converter with high performance which can easily be manufactured ad the optical isolator which uses it can be obtained.

IPC: G11B11/105
Filed: 1990-04-04
Abstract: PURPOSE:To reduce the mass of a movable part to perform access and to shorten access time by providing only a simple passive function without a driving system in the access movable part.

Title: Combustion chamber of mechanism of suppressing sticking of deposit
Inventor: OTSUBO YASUHIKO
IPC: F02B77/04
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To decompose deposit in a combustion chamber, and semipermanently suppress sticking of the deposit by arranging photocatalysts on at least a part of an exposing surface of a parts exposing in a combustion chamber. SOLUTION: Photocatalysts are arranged on a side surface of an upper surface in a cylinder for composing a combustion chamber, a top surface of a piston 2, and a surface of an injection nozzle or an ignition plug 3. The photo catalysts are arranged by a method for coating the photocatalysts as a thin film. The photocatalysts are arranged as the thin film by means of, for example, such an impregnation method that a parts for arranging the photocatalysts is impregnated in aqueous solution dispersed photocatalyst grains, and the parts is taken out and dried. When the photocatalysts are arranged on an inner surface of the combustion chamber, photon having high energy is discharged by burning fuel in the combustion chamber, and thereby, an activated species is generated on each surface of the photocatalysts.  Since deposit is completely oxidized by the activated species, the deposit can be decomposed.

Title: Expandable polyvinyl chloride resin composition
Inventor: KOBAYASHI TAKAYASU
IPC: C08J9/04
Filed: 1983-05-24
Abstract: PURPOSE:The titled composition which can provide a light foam product by a conventional molding method, by filling a composition of a PVC resin and a blowing agent with hollow glass beads. CONSTITUTION:The titled composition formed by filling a composition of a PVC resin and a blowing agent with hollow glass beads (average outside diameter of 10-200mu) in an amount of preferably 150pts.wt. or below per 100pts.wt. PVC resin. Although an attempt has heretofore been made to fill a resin with hollow bodies such as ''shirasu'' balloons, no reduction in the weight of a molding has yet been achieved because most of the balloons are broken during molding. The hollow glass beads are those which are nondefective and nearly exactly spherical so that they are not broken by pressure during molding and a very light foam can be produced. In addition, when this composition is injection-molded, the molding cycle can be shortened by the heat-dissipating effect of the hollow glass beads.

Filed: 1989-04-12
Abstract: PURPOSE: To easily obtain the material which has a pore size larger than the pore size of a starting material and has an improved flow characteristic by forming the silicon skeleton bonded by reaction by molding of a suitable polyurethane foam structural body.  
     CONSTITUTION: The polyurethane based foam having an open-cell type pore structure and the pore size of 0.1 to 10 mm is prepd. as a carrier. On the other hand, a mixture contg. silicon powder, synthetic resin and volatile org. solvent and having the max. viscosity of 10 Pas is prepd. The pore structure of the carrier described above is coated with this mixture. Next, this foam is dried to remove the solvent residue and simultaneously the resin is partially cured to improve the adhesion of the silicon particles to the pore structure. The embedding of the silicon particles into the resin is thus stabilized. Next, the material is exposed to a heat treatment to decompose and remove the carrier and the cured resin at 200 to 600°C. The residual silicon skeleton is stabilized by the reaction bonding at a temp. higher than 1,200°C and is heated up to 1300 to 1,500°C.
