Title: Methanol switching type fuel cell system
Inventor: NAKAYAMA TAKASHI
IPC: H01M8/04
Filed: 1993-12-15
Abstract: PURPOSE:To save fuel and prevent the overheating of a reformer by taking out and using a part of the fuel gas from a cell fuel electrode to a reformer burner as methanol heating fuel, when methanol is used as material gas. CONSTITUTION:Town gas is mixed with steam from a steam generator 5, reformed through a reformer 2 having a reforming burner 3, and then further passed through a shift converter 6 to form a hydrogen-rich gas. This gas is supplied to the fuel electrode of a fuel cell body 1 to generate electricity. Thereafter, the fuel gas discharged from it is supplied as the fuel for the burner 3. When the supply of the town gas is stopped, this is detected by a pressure switch 18, and the material gas is switched to the methanol from a methanol tank 20. This methanol is heated, superheated and evaporated with a circulating heat medium by heat exchangers 23, 24, and supplied to the reformer 2. The heating of the heat medium is carried out by taking out a part of the fuel gas by a branched pipe 14 and burning it by a gas burning heater 28.

Title: Communication sheet and material thereof
Inventor: KIMURA YOSHIKAZU
IPC: B32B27/10
Filed: 1989-12-01
Abstract: PURPOSE:To easily form a data laminate by using two transparent synthetic resin films having different softening/melting temps. against heat. CONSTITUTION:The printing of data is performed to paper A and each of data laminates B is prepared based on one pasteboard. A transparent synthetic resin film 3 is permanently bonded to the paper A as the first layer and formed from a synthetic resin having relatively high softening/melting temp. against heat, for example, polyester. Next, a transparent pseudo adhesive film 4 is bonded (falsely bonded) to the film 3 as the second layer. The film 4 formed from, for example, polyethylene having softening/melting temp. lower than that of the film 3. The pasteboard 1 is cut off from the paper A and the pasteboard 1 becoming a single body is folded along fold lines 2 so as to turn the film 4 of the second layer to the inside and bonded under heating and pressure. Since the opposed surfaces (second layer) bonded under heating and pressure are homogeneously integrated, they are not released even when a recipient applies force for opening a concealed surface and only either one of the pseudo adhesive layers 6a, 6b of the first and second layers is released. As mentioned above, a desired data laminate B can be processed without paying attention to the control of temp. or pressure.

Abstract: PURPOSE:To obtain a PPGA structure wherein outer leads do not have any short, even if voids develop in outer sealing material, by previously filling the upper part of a through hole with a solder resist, epoxy resin, etc., in order that the solder may not creep up in the voids. CONSTITUTION:A solder resist 4 is formed on the aperture 14 of a through hole 2 arranged on the periphery of a base 1 composed of resin like glass-epoxy, and the creeping-up of solder at the time of PPGA soldering is prevented. An outer lead 3 is pressed into the through hole 2, and solder is spread between the through hole inner wall and the outer lead and around the outer lead by solder-plating. After the outer lead is fixed to the base, resin like solder resist is spread on a wiring layer 15 and a region except a stage. Then the solder resist is again spread on the base upper surface containing the upper part of the through hole. Thus the aperture of the through hole is closed, and then the resist is hardened by heat-treating. Since the aperture of the through hole is closed by solder resist, the creeping-up of solder can be prevented, and a PPGA is manufactured after each specified process.

Abstract: PURPOSE:To supply a sufficiently strong light power even if output side optical fibers are >=3 pieces by bringing an input side optical fiber and the output side optical fibers into tight contact with both end faces of a waveguide provided to the active layer of a semiconductor laser with a waveguide mechanism. CONSTITUTION:The waveguide 20 of a prescribed width is provided to the active layer 11 of the semiconductor laser 10 with the waveguide mechanism and the exit end face of the input side optical fiber 1 is adhered and fixed to one end face thereof. The incident end faces of the plural output side optical fibers 2-1-2-5 are fixed to the other face of the waveguide 20 in tight contact therewith. Since the current below the threshold value is injected to the semiconductor laser 10, the semiconductor laser is in an excited state and the light entering from the input side is increased in the intensity thereof as the induced release progresses. The amplification of the light is thereby generated. The light power stronger than the power at the time of the incidence is thereby obtd. This power arrives at the exit face of the waveguide 20. The sufficiently strong light power is thus supplied even if the fibers are >=3 pieces.

Title: Adsorbent
Inventor: KITAGAWA HIROSHI
IPC: C01B31/08
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To obtain outstanding adsorptive properties by preparing an absorbent from the carbide of a chitinous substance which is the organic skeletal substance of the Crustacea such as a crab or a shrimp. SOLUTION: A chitinous substance recovered from the shell of a crab or a shrimp is carbonized when manufacturing an adsorbent. In this carbonization, the chitinous substance is baked at temperatures of 500-1000 deg.C, preferably 600-900 deg.C in the atmosphere of an inert gas containing substantially no oxygen at all. Consequently, the chitinous substance is converted to a carbide at a carbon yield of 20-32wt.% preferably 20-25wt.%. In addition, when carbonizing the chitinous substance, a gas with reactivity with carbon such as steam, carbon dioxide or oxygen is caused to chemically react with the obtained carbide after the carbonization process to obtain an active carbon with an activated surface. In this case, the activating treatment is performed normally at temperatures of 800-1100 deg.C.
