Patent JP-H01304682-A (JP)
Title: Temperature self controlling heat radiating body
Inventor: ISHII TAKAHITO
IPC: C08K3/00
Filed: 1988-06-01
Abstract: PURPOSE:To keep the flexibility and lower manufacturing cost by cross-linking a mixed and kneaded composition containing a crystalline resin, a raw material rubber, and a conductive powder not by a radioactive ray but another method. CONSTITUTION:A crystalline resin is retained by a rubber having the three dimensional molecular structure so as to prevent the crystalline resin from lowering its viscosity drastically at the temperature close to or more than its melting point and also prevent a conductive powder from cohering. Cross- linking is carried out by adding a cross-linking agent. For example, a crystalline resin of a low density polyethylene and a raw material rubber are previously mixed and kneaded each other by a hot roll at 170 deg.C, carbon black is added to the mixture, the resulting mixture is further mixed and kneaded, 1.5% of a peroxide cross-linking agent is added to the mixture, and the obtained mixture is press-formed at 170 deg.C. Because a radioactive ray is not used for cross-linking, the manufacturing cost is made low, and due to addition of the rubber, a temperature self controlling heat radiating body having good elasticity and high flexibility is prepared.

Title: Fuel cell
Inventor: OTAKE TETSUYA
IPC: H01M8/02
Filed: 1986-06-13
Abstract: PURPOSE:To realize high density, increase mechanical strength and thereby improve sealing performance by heat-treating the predetermined place on the periphery of an electrolyte plate or the whole region of the contacting surface with separator plates by optical means or electrically heating means. CONSTITUTION:An electrolyte plate 1 treated by optical means using laser or the like or by electrically heating means can increase conpressive strength and improve preventive effect against the occurrence of creep because of being melted, recrystallized and becoming sintered ceramics. And as the facial pressures of sealed parts 8 can be enhanced because of the increase in the compressive strength, preventive effect against gas leakage out of a cell is increased and thereby cell performance is improved. Furthermore, because on heat-treating the sealed parts 8, these become high density sintered substances, the electrolyte does not happen to sputter out of the cell and therefore the cell life can be elongated.

Title: Heat resistant scale preventing agent
Inventor: SHIOJI NAOTAKE
IPC: C02F5/10
Filed: 1985-06-24
Abstract: PURPOSE:To obtain the scale preventing agent having a superior heat resistance which can be used for geothermal generation of electricity, etc., without hindrance by polymerizing acrylic acid and/or methacrylic acid up to a specified polymerization degree in the presence of a specified amount of hypophosphorous acid and/or hypophosphite. CONSTITUTION:Acrylic acid and/or methacrylic acid are polymerized in the presence of 0.002-0.2mol of hypophosphorous acid and/or hypophosphite based on 1mol of acrylic acid in order to produce the polymer having the polymerization degree of 5-500. This heat resistant scale-preventing agent can be used without hindrance for a moderate.high pressure boiler and the geothermal generation of electricity. The compatibility of said scale-preventing agent with a corrosion-proof agent of multivalent metallic series such as zinc salts, molybdenum salts, etc., or of amine series, and with a slime-controlling agent is more excellent than the compatibility with a salt-type polymer such as the sodium salts of polycarboxylic acid. In addition, the water-treating agent usually controlled by three liquids can be adjusted as one liquid composition and the pH adjustment while being used can be carried out easily, so the industrial utility value is very great.

Title: Anodizing method and device
Inventor: TAKANO MICHIAKI
IPC: C25D17/00
Filed: 1992-04-28
Abstract: PURPOSE:To form a good-quality insulating film with the surface smoothed with good productivity by stepwise or continuously increasing an inter-electrode voltage in anodization. CONSTITUTION:The current 21 and voltage 22 of a constant-current power source 10 for an oxidation tank 13 are plotted against time in a chart. The current I1 is fixed between times 0 and T3, and the voltage V is continuously increased. The current and voltage are continuously increased between times T3 and T4. When an insulating film is formed, the voltage is limited at time T4, the inter-electrode voltage is made constant, and the current is decreased. Consequently, the aluminum oxide film on the uppermost surface of an aluminum film is densified and smoothed.

Title: Manufacture of molding
Inventor: OOSE KATSUHISA
IPC: B29L31/00
Filed: 1983-07-26
Abstract: PURPOSE:To prevent possible blurring by forming a synthetic resin at parts receiving a luster from the one lower in the melting point than that at other parts when a specified portion of a molding made of a synthetic resin is melted with a heat radiation. CONSTITUTION:A part YA to receive a luster is molded from a resin P1 lower in the hot meltin temperature than the one P at other parts covered with a mask F with the irradiation of light from a lamp apparatus 9. A ridge H is provided on the synthetic resin P1 side of a part corresponding to the border at both ends of the part YA to receive a luster. In this case, the open rim of the mask F corresponds to the projected section H, which facilitates the formation of molding comprising two synthetic resins P and P1 different in the melting temperature with an extruder 8. With such an arrangement, based on the heat irradiation of the light from the lamp apparatus 9, the synthetic resin P1 at the part YA to receive a luster is melted more quickly than that at other parts to ensure a luster. Even when light leaks from the space between the opening rim of the mask F and the molding M, the synthetic resin P at the leaked part is high in the melting point and is so hard to melt to be freed from blurring.

IPC: H04M3/46
Filed: 1978-11-06
Abstract: PURPOSE:To enhance the service for the caller by securing an automatic transfer for the call signal to other subscriber within the same group in case the called subscriber telephone does not have the off-hook within the fixed time. CONSTITUTION:When the incoming is given to subscriber telephone set 1, the call signal transmission part of subscriber line circuit 3 is started by control circuit 4, and the call signal is transmitted to subscriber line 2 connected to ring the bell of telephone set 1. And the time is counted at subscriber's answer detection part 7 from the operation start of call signal transmission part 6 in circuit 3 to the off-hook of telephone 1. In case no off-hook is given within the fixed time, other subscriber within the same group is called through the action of switch frame 5. Thus the call signal is transferred automatically to other subscriber within the same group in the fixed time even in case the called subscriber gices no answer. As a result, the service can be enhanced for the caller.
