Abstract: PROBLEM TO BE SOLVED: To provide a process for producing an enamel member capable of reproducing an extremely meticulous color photograph by using photograph transfer sheets. SOLUTION: A stage for firing glaze corresponding to the finish color of an enamel surface exclusive of the part to be stuck with the photograph transfer sheets is executed after the firing of the photograph transfer sheets, and the firing of the glaze corresponding to the finish color of the enamel surface is executed at the firing temp. of the firing of the photograph transfer sheets, by which only the ground coating 4, cover coating 5 and first photograph transfer sheet 6 are formed between a base metallic plate 3 and the second photograph transfer sheet 7. The spacing is made smaller by as much as the glaze- component corresponding to the assigned finish color. The occurrence of the phenomenon that an enamel layer is crushed is substantially obviated and the crushing of the enamel layer and the occurrence of the crack in the inside is averted even if the temp. elevating and cooling are repeated at each of the respective firing stages.

Title: Improved electrode
Inventor: WILKINSON DAVID PENTREATH
IPC: H01M4/90
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To prevent the functional deterioration of an electric catalyst caused by a polluting poisoning action by physically contacting a first catalytic component having activity in a gaseous phase reactive part and a second catalytic part having activity in an electrochemical part with each other. SOLUTION: A first catalyst component reduces the concentration of a polluting poisoning substance by treating a reaction gas flow. The polluting poisoning substance contains CO and CO2 from a reformed gas flow, and also contains a compound containing sulfur or nitrogen from an acid posison gas flow. A second catalytic component is selected so as to increase electrochemical reaction speed under the existence of a reaction gas flow containing the polluting poisoning substance. It is proper that the first and the second catalytic components are arranged so that the reaction gas flow contacts with the first catalytic component in the first place and contacts with the second catalytic component thereafter. For example, platinum is used as the first catalytic component, and for example, a mixture of platinum and ruthenium is used as the second catalytic component.  It is desirable that the respective catalytic components become layers separated from each other in an electrode.

Title: Input-output channel unit
Inventor: OGAWA TETSUJI
IPC: G06F3/00
Filed: 1979-07-06
Abstract: PURPOSE: To make it possible to connect input-output equipments differing in throughput by carrying out data transfer by decreasing a skew compensation value when the throughput of the input-output equipment is large while increasing it when small.  
     CONSTITUTION: For the purpose of coupling input-output equipments differing in device throughput, it is necessary to recognize whether a skew compensation value of 50nS or 100nS is suitable for a selected input-output equipment. For example, when the skew compensation value of 50nS is suitable for the selected input-output equipment, signal MarKo.in of level "1" is output from the corresponding input- output equipment synchronizing with signal Operational.in. At this point in time, since signal Address.out is sent out, the AND condition of AND circuit 44 of an input-output channel unit is realized and FF40 is set by its output. Namely, the input-output channel unit selects the skew compensation value of 50nS and controls the following data transfer. Similarly, when signal MarKo.in is "0", the skew compensation value of 100nS is selected.

Title: Detecting method of amount of cooling medium liquid in boiling cooling apparatus
Inventor: WATANABE TAKASHI
IPC: G01F23/28
Filed: 1991-04-17
Abstract: PURPOSE:To detect the displacement of the surface of a cooling medium by providing a light emitting element inclined a predetermined angle to the surface of the cooling medium and a photodetecting element confronting the light emitting element respectively at a predetermined depth in the cooling medium, thereby detecting the amount of liquid based on the intensity of the detected light. CONSTITUTION:A liquid phase cooling medium 3 is changed to a gas phase cooling medium 10 because of the heat generated from a semiconductor device 1, condensed in a container 2 and returned to a liquid-phase medium. At this time, part of the medium dissipates, consequently lowering the liquid level. When the liquid level is as indicated by a solid line 11, a light emitting element 7 and a photodetecting element 9 are in the liquid. If an optical axis connecting the light emitting element 7 with the photodetecting element 9 is inclined a predetermined angle to the surface of the cooling medium and the liquid level is at the position of a chain line 12, the photodetecting element 9 is exposed and the light is totally reflected at the liquid surface, without entering the photodetecting element 9. Therefore, by measuring the intensity of light by means of the photodetecting element 9, it can be detected whether or not the cooling medium liquid is at the predetermined level.

IPC: H05F1/02
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a device in which heating, cooling, releasing, etc., of a sheet material can be easily performed by providing a holding member of electric insulation provided with a specific surface, and specifying a relation of between the maximum height of the surface and thickness of the holding member. SOLUTION: A holding device 1 comprises a holding member 11 of electric insulation provided with a surface to get in contact with a sheet material 2 of electric insulation for holding the sheet material 2. Relation between the maximum height Rmax of the surface and thickness (t) of the holding member 11 is set to satisfy 10μ<=Rmax <=t<=10mm, so electrification can be restricted to easily hold the sheet material 2 of electric insulation. The holding member 11 thus becomes hard to be damaged by static discharge. Deterioration of heat conductivity efficiency to the sheet material 2 can be restricted. By setting vertexes of protruded parts 111 in the holding member 11 which get in contact with the sheet material 2 to exist in the same plane as far as possible, mechanical and thermal load on each protruded part 111 can be favorably reduced.

Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To improve yield and reliability while realizing multi-function and large capacity by applying adhesive to a fixed region of a junction region of a multilayer board with a specified conductor path. SOLUTION: Linear adhesives 9A to 9D whose total application area is smaller than that of a chip junction region at a rear side of a multilayer board 1 constituting a composite type lead frame 4 are applied thereto.
