Title: Electric heater
Inventor: MIYAGAWA HARUMITSU
IPC: F24D13/02
Filed: 1989-01-19
Abstract: PURPOSE:To prevent a malfunction of current flow to a heater by discriminating a disconnection of wire of a heat-sensitive body when a specific time passes after the current to the electric heater is started. CONSTITUTION:When a current flow to an electric heater 101 is started by a current flow control device 103, a clocking device 104 clocks a specific time from the starting of the current flow, and makes a comparing device 105 compare the impedance of a heat-sensitive element 102 with a specific value. The heat-sensitive element 102 is heated by the electric heater 101, but since the impedance of the heat-sensitive element 102 is not reduced lower than the specific value even though the specific time passes after the current flow starts to the electric heater 101, when the heat-sensitive element 102 is disconnected, the comparing device 105 makes the current flow control device 103 stop the current flow to the electric heater 101. Consequently, even though a heat- sensitive element 102 with an extremely high negative temperature coefficient of impedance is used in a low temperature condition, the current flow control device 103 generates no malfunction.

Abstract: PURPOSE: To rapidly carry out the discharge of impurities from furnace released from the substrate and repressing the auto doping and also, to prevent the decrease of growth velocity of epitaxial layer, by periodically changing the pressure of gas in reaction furnace.   
     CONSTITUTION: The carrier gas 6, the source gas 7 (for example; SiH 4 ) and the doping gas 8  (for example; AsH 4 ), are induced to the reaction furnace 5 and the substrate 1 composed of Si  single crystal having filling layer containing highly concentrated As on the susceptor 4, is heated  at a fixed temperature. On this ocassion, the vacuum pump 10 is provided between the furnace 5  and the exhaustduct 9 and epitaxial growth is carried out keeping the furnace 5 at low pressure  less than 100 Torr. Meanwhile, the valve for low pressure 11 is periodically opened and shut and  the valve for high pressure 12 is maintained at always opening state. That is, the pressure of the  furnace 5 is lowered and discharge of impure particle released from the substrate 1, is accerelated  at the state of opening the valve 11. The pressure of the furnace 5 is made high determined by  the valve diameter of the valve 12 and the epitaxial growth is accerelated at the state of shutting  the valve 11. That is, the epitaxial layer slightly affected by the impurities in the substrate 1, is  obtained.

Title: Methane fermentation
Inventor: KANAI MASAKUNI
IPC: C12P5/02
Filed: 1979-01-31
Abstract: PURPOSE: To shorten the fermentation time of raw garbage, and to improve the production efficiency of methane, by grinding the raw garbage mechanically to a juicy state containing the finest possible solid particles, and if necessary, introducing CO 2  gas uniformly to the garbage during the fermentation.  
     CONSTITUTION: Raw garbage is mechanically powdered to a juicy state, and fermented with a digesting sludge. The so-called acidic fermentation period is eliminated, and the methane fermentation proceeds at a high rate from the start, and consequently, the fermentation time can be reduced to 1/3 of the conventional process. When the fermentation is carried out in a CO 2  atmosphere, the amount of methane can be doubled, supposedly because of the generation of hydrogen gas by bacteria, etc. The yield of methane production can be further improved by introducing CO 2  gas continuously to the reaction system.

Title: Dry etching
Inventor: TATSUMI TETSUYA
IPC: H01L21/302
Filed: 1990-01-22
Abstract: PURPOSE:To make possible an anisotropic etching while protecting sidewalls mainly with a reaction product obtained through the reaction of a resist material with Br without using fluorocarbon by a method wherein fluorine gas containing HBr is used as etching gas. CONSTITUTION:According to etching gas obtainable by mixing fluorine gas and HBr in a proper ratio, respective weak points are covered complimentarily to each other. That is, an etching rate of a practical level is reliably held with the high-reactivity fluorine gas, a resist material is effectively sputtered with the HBr of a large mass to form a reaction product and the product is deposited on the sidewall parts of a polycide film. Accordingly, the generation of an undercut in a polycrystalline silicon layer is prevented. Moreover, H being contained in the HBr contributes to the decomposition of the resist material and excessive fluorine radicals in a system are trapped and can be removed in the form of a hydrofluoric acid. As the etching gas makes a high anisotropy, a low contamination, a high selectivity and a high-speed etching reaction proceed in such a way, the gas is promising as a substitute for flon gas which has been hitherto used versatilely as etching gas for the polycide film.

Title: Tracking antenna device
Inventor: WATANABE HIDEKI
IPC: H01Q3/02
Filed: 1983-01-26
Abstract: PURPOSE:To eliminate of unbalancing of a rotating system and to miniaturize the device by arranging a rotor in a direction where a moment of inertia generated by an antenna itself to a rotary shaft and that of the rotor are balanced. CONSTITUTION:The moment of inertia M1 generated by the antenna 1 to the rotary shaft 5 is cancelled by making the rotor 4 of a rotating machine asymmetrical to the rotary shaft 5 and balancing the moment with the moment M2 of the rotor 4. Magnets 8 are fixed in the semicircle form to the rotary shaft 5 of the rotor 4, for example, and a coil 9 is arranged in the range of shaking angle of the antenna 1. In forming the rotor 4 and the coil 9 in this way, a distance L1 between the antenna 1 and the rotary shaft 5 is decreased and since the moment of inertia of the antenna 1 is decreased in proportion to the 2nd power of the L1, the load energy of the rotating machine is reduced. When the relation of M1>M2 exists, it is necessary to add a dummy way but the weight is decreased. Thus, it is possible to eliminate the unbalancing of the rotating system and the device is miniaturized.

Title: Distortion quantity detecting method for steel material or the like
Inventor: KAWANO HAJIME
IPC: G01N21/91
Filed: 1986-01-23
Abstract: PURPOSE:To detect a working distortion at any time by converting the generation quantity of a slide in a crystal grain to a fixed quantity. CONSTITUTION:A polycrystalline substance of copper, etc., is subjected to a working distortion, and when its magnitude reaches a level of some extent, a slide starts to be generated in a crystal grain. A slide 2 which has been generated in the inside of this crystal grain 1 is not erased even by destaticization, and increases suddenly as the working distortion increases. An appearance frequency of the slide is generally governed by the working distortion,therefore, by converting the generation quantity of the slide to a fixed quantity, the working distortion is detected. As for a detecting method of this working distortion, a method for detecting the distortion quantity from a relation of the density of a slide line and the working distortion is used, by processing an image of a polycrystalline substance which has been brought to an image pickup, as a binary image containing a crystal grain boundary and the slide line generated in its inside, and obtaining an image of only the slide line by subtracting the same binary image being in a non-distortion state.

Abstract: PURPOSE:To use an air permeable metal plate material as a hydraulic pressure detecting member by covering a metal plate in which many pores are formed with a water repellent coating, selecting diameters of the pores and a coating agent, and setting a hydraulic pressure for switching from non water permeability to water permeability. CONSTITUTION:Pores each having a diameter of 100-900mum are formed at a metal plate material made of stainless steel, etc., and having a thickness of about 0.004-1mm. The material is covered with a coating of 6-p- perfluorooctylanilino-1, etc., to form a water permeable metal plate material. For example, the plate 6 is assembled with a water level gage 13, and disposed on the way of a water distribution tube 12 for connecting a water source 10 to a water tank 11. When water in the tank 11 exceeds a set value, the plate 6 is changed to water permeability by a hydraulic pressure applied to the plate 6, and excess water is returned from the gage 13 to the source 10 via a branch tube 14. The gage 13 of this type is scarcely affected by influence of coil water in the tank 1 as compared with an overflow type water level gage and can maintain stable performance for a long period.
