Title: Surface modification of aluminum nitride substrate
Inventor: ISHII MASAYUKI
IPC: C04B41/80
Filed: 1989-12-04
Abstract: PURPOSE:To obtain the title ceramic substrate excellent in heat releasability by forming an oxide layer on at least one surface of an aluminum nitride substrate through plasma oxidation or thermal oxidation process. CONSTITUTION:An oxide layer is formed on at least one surface of an aluminum nitride substrate through plasma oxidation or thermal oxidation process. The thickness of this layer is suitably 0.02-1mu. Aluminum as a constituent of the nonoxide-based aluminum nitride ceramic represents extremely strong oxidation tendency, the resulting oxide being more stable than the nitride. Therefore, exposure of the aluminum nitride ceramic to high temperatures in an oxidative atmosphere such as the air or oxygen gas will form an oxide layer of Al2O3 on its surface. Alternatively, oxygen is ionized and the aluminum nitride ceramic is exposed e.g. to the state of a RF plasma of O2, thereby the surface of the aluminum nitride ceramic can easily be modified into an oxide surface of Al2O3.

Title: Multilayer substrate of aluminum nitride and manufacture thereof
Inventor: KURIHARA KOICHIRO
IPC: B32B15/04
Filed: 1987-12-11
Abstract: PURPOSE:To obtain an Al nitride multilayer interconnection board composed of a sintered piece provided with a protective oxide film formed on it without oxidizing the surface of a wiring metal by a method wherein a sintered piece is subjected to a heat treatment in a mixed gas atmosphere composed of nitrogen, oxygen, and water vapor. CONSTITUTION:A required metal wiring pattern is printed on a green sheet formed of Al nitride as a main component, and the green sheets are laminated and sintered for the formation of a Al nitride multilayer substrate. In this process, a sintered piece is subjected to a heat treatment in a mixed gas atmosphere composed of nitrogen, hydrogen, and water vapor. Then, a protective oxide film is selectively formed only on the surface of a ceramic except the wiring metal surface. The ratio of the partial pressure PH2O of water vapor to partial pressure PH2 of hydrogen in a heat treatment atmosphere is controlled to be within the range of 0.1-1. By these processes, a Al nitride multilayer interconnection board composed of a sintered piece on which a protective oxide film is formed can be obtained without oxidizing the surface of a wiring metal.

Filed: 1989-12-02
Abstract: PURPOSE:To continuously enable the ombre dyeing of a web in good repeatability and in a high quality by reducing the immersing lengths of the web in a dyeing solution in turn and simultaneously increasing the concentration of the dye in the dyeing solution. CONSTITUTION:A web 7 is hung with a hanging means 8 such as rolls while the immersing lengths of a web in a dyeing bath 1 are adjusted to such suitable those as to match to the ombre finish of the web 7 and dyed.

Title: Metallic mold for casting
Inventor: OHIRA MASAYOSHI
IPC: B22C9/06
Filed: 1990-11-21
Abstract: PURPOSE:To prevent internal blow hole and shrinkage hole in a product by supplying compressed air into a metallic mold from a gas vent to load pressure after completing casting without using a slide core. CONSTITUTION:Molten metal is poured from a sprue part 7 with the fixed mold 5 and the movable mold 6 and the air in the mold is discharged to out of the mold from the gas vent 3 through a feeder head 2 by opening a valve 4.

Title: Breaker operating mechanism with hydraulic pressure
Inventor: TAKETOMI YUKIMASA
IPC: H01H33/30
Filed: 1990-11-21
Abstract: PURPOSE:To prevent drop of oil pressure even when a power supply for an oil pump has gone out, by furnishing a liquid leak device consisting of a solenoid valve between the high pressure system and low pressure system, equipping the high pressure system with a pressure switch whose actuating difference pressure is below a certain specified level, and thereby holding the 3-phase out-of-alignment time under a certain value. CONSTITUTION:A liquid leak device 20 consisting of a solenoid valve 21 is furnished between the high pressure system 7 and low pressure system 10, and the amount of oil leak from the high pressure 7 to low pressure system 10 is controlled by the solenoid valve 21. That is, a pressure switch 12 is turned on with pressure boost of the high pressure system 7 due to rise of the ambient temp. to perform oil leaking from the liquid leak device 20, and with pressure down the same pressure switch 12 is turned off. This prevents a circuit breaker concerned from getting high pressured, and precludes down to the atmospheric pressure in case the power supply for motor goes into failure, and further can limit the 3-phase out-of-alignment time below a certain value.

Title: Thin type lead storage battery
Inventor: TANAKA AKIFUMI
IPC: H01M10/12
Filed: 1986-12-26
Abstract: PURPOSE:To enable much thinning by using metallic plates in a battery jar of a thin type lead storage battery and making these plates serve as reinforced matters and collector terminals. CONSTITUTION:A positive electrode 1 and a negative electrode 2 are kept in touch with inner surfaces of lead plates 4 and 5, respectively, which serve as terminal plates. In this composition, a prescribed additive is added to lead powder so as to form paste, and pasted plates in fixed thickness are formed from this paste by means of a filling machine. Since initial charging after cutting these plates requires time, the plates are cut into electrode plates of prescribed sizes after the completion of the initial charging. Though conventional electrode plates require to have lattices built-in in order to decrease resistance, the electrodes in this battery do not especially require to have the lattices built in because sides of the electrode plates are in touch with the terminal plates 4 and 5. Hence, even if the positive electrode 1 and negative electrode 2 are thinned, capacity per volume can be increased because a loss component due to the lattices does not exist. Required thickness for the paste is 0.5mm or so because of no lattice in existence. The lead plates 4 and 5 are terminal plates of the positive electrode 1 and the negative electrode 2, respectively, and they serve as a battery jar of a thin-type lead storage battery.
