Patent JP-2000106394-A (JP)
Title: Low-permittivity material for manufacture of integrated circuit
Inventor: WAYMING LEE
IPC: C23C16/30
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain the insulating material having the low permittivity for electrical isolation in a high-density integrated circuit. SOLUTION: This is the method for forming electrical isolation between the dielectric elements in an integrated circuit. The substrate having the partially manufactured circuit is provided. Organosilane-gas source is reacted with oxidizing agent, and a layer is formed on the substrate. Furthermore, the formed layer mainly comprises silicon hydroxide and includes carbon atoms. The silicon- hydroxide layer undergoes plasma processing during the plasma processing without forming a layer. Thus, the silicon-hydroxide layer is converted into the insulator body having the lower permittivity. This is the method including these processes.

Title: Facsimile equipment
Inventor: NAKAMURA MITSUO
IPC: H04N1/40
Filed: 1993-09-14
Abstract: PURPOSE:To obtain a read image that is less soiled by controlling the reading of the image in accordance with the soil of an image reading part. CONSTITUTION:An image reading part 2 reads a white image when no original is inserted. When the output of the white image read by the part 2 includes the information on the images other than the white one and less than the reference white level set by a white level setting means 4, these information are detected by a soil detecting means 3. The means 4 changes the reference white level when the means 3 detects the preceding information less than the reference white level. Thus the information on the images other than the white one are not read by the means 4.

Title: Method for holding piezoelectric oscillation parts
Inventor: NISHINO JUNICHI
IPC: H03H9/05
Filed: 1986-10-21
Abstract: PURPOSE:To hold piezoelectric oscillators with certain pressure even if the dimensions of connection terminal plates, etc., have variance by inserting pressure sensitive electrically conductive rubber sheets between the piezoelectric oscillators and the connection terminal plates with pressure more than the certain pressure and inserting a pressure plate into a holding member until the sheets are conducted. CONSTITUTION:The piezoelectric oscillators 21-26 have electrodes formed on the both sides of a piezoelectric ceramic substrate, while the connection terminal plates 4-13 adjoin to the oscillators 21-26 and electrically connect them. With the connection terminal plates 4-13 laminated, the piezoelectric oscillators 21-26 are pressed and held in the holding member 15. The pressure sensitive electrically conductive rubber sheets 1a and 1b that are conducted due to pressure over the certain one are inserted between the piezoelectric oscillators 21-26 and the connection terminal plates 4-13, and the pressure plate 16 is inserted in the holding member 15 until the rubber sheets 1a and 1b become conductive. Thus the pressure of holding both the piezoelectric oscillators 21-26 and the connection terminal plates 4-13 is gradually raised. When it is detected that the pressure sensitive electrically conductive rubber sheets 1a and 1b become conductive, an appropriate holding pressure is identified. Thus the force of holding the piezoelectric oscillators can be optimized.

Title: Buoy excellent in external-pressure resistance
Inventor: TAKEMAE EIJI
IPC: B63B5/24
Filed: 1984-11-28
Abstract: PURPOSE:To obtain a relatively small buoy, by covering the outer surface of a high-density polyethylene foam material floating member with an outer skin made of rubber, etc. to enhance the external pressure resistance of the buoy and to decrease a loss in buoyancy thereof due to a decrease in its bulk. CONSTITUTION:An outer skin 14 made of rubbers, polyethylene, etc., is coated on a float member 12 made of high-density polyethylene foam materials to form a buoy. A core metal 16 is inserted through the buoy, as necessary, and a sling hardware 18 and a connecting hardware 20 are attached to the top and bottom ends of the core metal 16. Since the bulk change rate of high-density polyethylene form materials is less even if external pressure is applied and therefore, it has a characteristic in excellent in external pressure resistance, a loss in buoyancy may be made to be less as a buoy. Accordingly, if the buoy has the same characteristic as that of the conventional one, the shape of the entire buoy may be made to be small.

Title: Fuel injection device for multicylinder internal combustion engine
Inventor: ITO YASUSHI
IPC: F02D41/34
Filed: 1991-09-30
Abstract: PURPOSE:To perform accurate estimation of an actual injection amount of each injection valve by a method wherein fuel is previously injected through all injection valve for a specified time before injection of one injection valve prohibited after injection of fuel through the other fuel injection valve is prohibited. CONSTITUTION:When an injection amount of a fuel injection valve 400 is individually estimated, injection of one injection valve among fuel injection valves 400 is prohibited by a fuel injection prohibiting means 405 during the stop of the feed of fuel by means of a fuel feed stopping means 404. During the injection prohibiting time, a fuel injection amount estimating means 406 determines an amount of fuel pressure reduction in a fuel passage 401 occurring owing to injection of fuel through other injection valve by means of a fuel pressure detecting means 403, and based on the result, an actual injection amount of the injection valve is estimated. In this case, a fuel injection control means 408 restarts injection all cylinders after prohibition of injection through a first injection valve. Estimation of an injection amount of a second injection valve is not executed before the given number of times injection of fuel through the first injection valve is completed. This constitution enables an actual injection amount to coincide with a target injection amount with a high precision.

Title: High frequency heating device
Inventor: HASEGAWA YUTAKA
IPC: H05B6/78
Filed: 1987-10-07
Abstract: PURPOSE:To make it possible to use the titled device in a range of a large current densities by coating the inner surface of an oven and the surface of an inner structure of metal provided in the oven with a ceramic insulating matter. CONSTITUTION:In a high frequency heating device of an oven type, the inner surface of the oven 1 and the surface of an inner structure of metal inside the oven are coated with insulating matter 2 of ceramic. By this, discharge is less likely to occur between the surfaces of the inner walls of the oven 1, between the surface of the inner wall of the oven and the surface of the inner structure, between the surfaces of the inner structure, etc. In addition, if friction occurs at the surface of the inner walls of the oven 1 and the surface of the inner structure of metal provided in the oven 1 caused by a heated matter or the like, the insulating matter 2 will not peel but keep the action of insulation. The titled device can thus be used in a range of larger current densities than conventional devices.
