Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To make peeling of a coating layer difficult and to solidly bond it, by setting a carbon fiber reinforcing carbon combined material as a base material, setting a base material surface layer part to be a SiC coating layer by a conversion method, and forming the combined coating layer of Si and SiC, which are vapor-deposited by means of a CVD method or a pulse CVI method, on the layer. SOLUTION: The carbon fiber reinforcing carbon combined material (C/C base material) becoming the base material is obtained by immersing and sufficiently wetting matrix resin liquid in the woven fabric of the plain weave and the twill weave of carbon fiber, felt or tow, tacking it and forming a prepreg. Then, it is stacked, pressurized and is formed. The SiC coating layer by the conversion method is formed on the surface layer part by using the carbon of the C/C base material as a reaction source, reacting it with SiO gas. Then, it is converged into SiC and it is formed. The combined coating layer of Si and SiC, which are vapor-deposited by applying the CVD method or the pulse CVI method, is formed and coated on the surface of the SiC coating layer. The occurrence of crack or peeling can be suppressed even if a severe heat cycle is given.

Title: Manufacture of semiconductor device
Inventor: FUKUCHI JUN
IPC: H01L29/41
Filed: 1990-01-29
Abstract: PURPOSE:To miniaturize large capacity devices, such as static RAM by forming gate insulation film and a first polycrystal silicon film and then etching substrate silicon so that its surface may be dug or engraved and then forming a second polycrystal silicon film and dry-etching wiring patterns after having doped impurities. CONSTITUTION:After an insulation film 2 and a first polycrystal silicon film 3 are formed on a semiconductor substrate 1, a contact section 4 is formed by dry-etching the insulation film 2 and the first polycrystal silicon film 3 to such an extent that the semiconductor substrate may be slightly engraved. continuously with that, the contact section 4 between the semiconductor substrate 1 and a second polycrystal film 5 is formed by forming the second crystal film 5, ion plantation, and interconnection patterns formation. This construction makes it possible to prevent the generation of contact leak and the deterioration of separation pressure resistance due to silicon engraving at the contact section 4 which has been subjected to troubles when patterns miniaturization is called for, thereby largely contributing toward the miniaturization of large capacity device, such as stack RAM which use silicon contact.

Title: Washing machine
Inventor: AKINAGA NORIMASA
IPC: D06F37/36
Filed: 1993-02-05
Abstract: PURPOSE:To prevent a filter from clogging with granular detergent by providing a dissolving process of a detergent in which a pulsator is driven to generate a relatively weak water flow before the washing process, in a washing machine having a collecting function of waste thread or the like by the circulation of washing water. CONSTITUTION:When a detergent is fed in the inlet of detergent, the detergent is held in the recession 3 at the bottom of the washing and spin-drying tank 2 through the circulation path 6. Then when a water supply solenoid valve 35 is turned on to feed water up to the dissolving water level of the detergent, a pulsator 4 is driven so as to generate a weaker water flow than the rinsing water flow in the rinsing process to dissolve the detergent held on the bottom of the recession 3. In this time, since the water level is low and the water flow is also weak, the circulating and draining action is not brought. When a specified time has elapsed and the solenoid valve 35 is again turned on and water is fed up to the washing water level, the pulsator 4 is driven as usually and hence, water is sucked into the recession 3 and drained from the outlet 5 through the circulation path 6. Accordingly, waste thread in the washing water is collected by the filter 18.

Title: Optical multiplexing and demultiplexing element for three-direction mutual transmission
Inventor: MIYAJIMA YOSHIAKI
IPC: G02B6/293
Filed: 1988-01-29
Abstract: PURPOSE:To miniaturize a unit by giving an integrated waveguide structure to a three-direction transmission element. CONSTITUTION:When a conductor B1in is connected to an input port 21 of a multiplexing and demultiplexing element with respect to the connection constitution between the multiplexing and demultiplexing element in a branching unit 13 and fiber conductors, propagated signal components lambda1 and lambda2 are demultiplexed and are emitted to output ports 28 and 30 respectively. The component lambda1 is emitted to a port 34 from a port 28 through a port 27 if the port 28 is connected to a port 27. When fiber conductors A1out and C1out are connected to ports 30 and 34 respectively, the wavelength lambda1 is used to enable transmission from B to C, and the wavelength lambda2 is used to enable transmission from B to A. Similarly, the wavelength lambda1 is used to enable transmission from A to B, that from B to C, and that from C to A, and the wavelength lambda2 is used to enable transmission from B to A, that from A to C, and that from C to B. Thus, the branching unit is miniaturized because the three-direction optical multiplexing and demultiplexing function is realized with the micro-sized element.

Title: Ceramic heater
Inventor: SHIMOTSURU HIDEAKI
IPC: H05B3/14
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To sufficiently endure use in a special atmosphere, detect an accurate temperature of heating resistors themselves, and heat a heating object to a desired temperature on the basis of a detecting temperature by juxtaposing temperature sensing resistors in a heating area of the heating resistors in a ceramic body. SOLUTION: Temperature sensing resistors 3 to be used as a temperature sensor are juxtaposed over the whole area of a heating area K together with heating resistors 1 densely embedded in the heating area K on a green sheet S1 of ceramics. The raw sheet S1 on which the heating resistors 1 and the temperature sensing resistors 3 are juxtaposed, is integrally sintered in a baking atmosphere after being sandwiched and laminated on a columnar core material S2 formed on a material similar to the green sheet S1. Therefore, the temperature sensing resistors 3 accurately and sharply sense not a temperature of a heating object but a temperature of the heating resistors 1, and a ceramic heater H can be made to act with the highest reliability regardless of properties and a condition of the heating object.
