Title: Production of element for oxygen density sensor
Inventor: SHIMAZAKI SHINJI
IPC: G01N27/409
Filed: 1977-10-19
Abstract: PURPOSE: To improve the adhesion of platinum electrode without decreasing the mechanical strength of ZrO 2  ceramics by sandblasting the surface of a ZrO 2  ceramics molding with ceramics powder of the same material then firing the ceramics and forming the platinum electrode on the roughened surface.  
     CONSTITUTION: The ZrO 2  ceramics raw material having been stabilized by CaO or Y 2 O 3  is molded to a specified shape. The surface of this molding is sandblasted with the ceramics powder of the same material as this. After the molding whose surface has been roughened is next fired, platinum is evaporated on said surface or platinum powder is oated and baked thereon. Thereby, the surface may be readily roughened and the possibility for producing strains and cracks as with sandblasing of burned products is eliminated. Further decreasing of mechanical strength will not occur because there is no etching treatment. Even if the powder at the sandblasting depostis on the molding, there is no fear for entry of foreign matter because it is of the same material

Title: Tilting type automatic molten metal pouring method
Inventor: SATO JIRO
IPC: B22D37/00
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of the quality of a product in advance by pouring a molten metal in a molding frame, tilting a ladle backward in the opposite direction to the pouring direction, and damping the vibration of the surface of the molten metal in the ladle to correctly control the molten metal pouring. SOLUTION: In an automatic molten metal pouring equipment 1, the molten metal in a ladle 2 is poured from a tapping port 3 to a down gate Mo of a molding frame 4 by tilting the ladle 2 clockwise around the axis O of revolution by a driving means 9. When the molten metal equivalent to one mold is poured, the ladle 2 is tilted backward at the maximum speed counterclockwise around the axis O of revolution by the driving means 9 in the opposite direction to the pouring direction, and when the ladle reaches the position where the molten metal is not spilled from the tapping part 3, the backward tiltation is stopped to smoothly perform the pouring cutting. The angle of backward tiltation is normally about 110 deg.. The residual vibration of the molten metal in the ladle 2 is eliminated to solve the problem of the sloshing of the molten metal in tilting the ladle 2 backward. Deterioration of the quality of the product due to inclusion of air and slag can be prevented.

Title: Compressing/expanding processing device
Inventor: SATO FUMITAKA
IPC: H03M7/30
Filed: 1988-05-24
Abstract: PURPOSE:To prevent compressing/expanding processing speed from being restricted by the access time of a reference line buffer by performing both the write processing and the read processing of reference line data within one step according to a prescribed clock. CONSTITUTION:The title device consists of a compressing/expanding processing LSI 10, the reference line buffer SRAM 16A and a clock generator 21, and one machine cycle is realized by two clocks from the clock generator 21. In a first halt cycle, the compressing/expanding processing LSI 10 writes the image data of a compressing/expanding processed result in the SRAM 16A through a data bus 15A, and in a latter half cycle, it reads out the reference line data written in the SRAM 16A, and executes alternately the operations of write and read in one cycle. Thus, the compressing/expanding processing speed is never restricted by the access time of the reference line buffer.

Title: Wick type kerosene burner
Inventor: SHIGEOKA TAKEHIKO
IPC: F23D3/08
Filed: 1990-05-17
Abstract: PURPOSE:To stop fuel supply to an evaporation part of a wick so that self-distinguishing takes place, by a method wherein a suction part of the wick is composed of resin fibers which easily melt by heat, and heat transfer plates made of metallic foil are attached on inner and outer surfaces of the evaporation part of the wick, so that the suction part melts down when the evaporation part is heated up to an abnormal temperature. CONSTITUTION:A wick 3 consists of a suction part 3A formed of polypropylene resin and others, an evaporation part 3B where fuel is supplied from the suction part 3A is evaporated, and heat transfer plate 3C and 3D which are made of stainless steel foil and others, cover the inner and outer surfaces of the evaporation part 3B except for the evaporation surface of its upper rim and serves as sliding parts contacting with inner and outer wick drums 4 and 5. Therefore, even in the case a hanging phenomenon occurs, the wick 3 is impossible to be moved up and down, and back-fire or overheat in the vicinity of the evaporation part 3B occurs due to wind, causing an abnormal combustion to start, the heat transfer plates 3C and 3D, which cover the surfaces of the evaporation part 3B of the wick 3, transfer the heat from a combustion part E to the lower part. Consequently, the suction part 3A made of resin fibers melts down by the heat, causing the capillary phenomenon to be perished. As a result, suction of liquid fuel 2 stops and self-distinguishing takes place, so that safety is maintained.
