Title: Load drive circuit
Inventor: YOMOGIHARA KOICHI
IPC: G05B9/02
Filed: 1991-04-02
Abstract: PURPOSE:To constitute a fail-safe mechanism which breaks power supply to a load when abnormality occurs by making the mechanism contactless. CONSTITUTION:A load 8 is fed with electric power from a switching power source 3 and, at the same time, the presence/absence of a fault in an SSR 9 which controls the power supply to the load 8 based on a drive command signal IN is detected by means of an impedance sensor 10. Then, when a short-circuiting fault occurs in the SSR 9, the switching power source 3 is stopped by generating a low-level output corresponding to a logic value '0' from the sensor 10 and stopping the output of a discrimination circuit 15. Therefore, a fail-safe mechanism for breaking the power supply to a load using the contactless switching power source can be constituted and the safety and service life of the mechanism can be remarkably improved.

Title: Elevator trouble detector
Inventor: WATANABE HIDENORI
IPC: B66B5/02
Filed: 1978-06-09
Abstract: PURPOSE: To prevent breaking of a semiconductor element by connecting a resonance circuit which synchonizes with the frequency six times or twice as high as the source frequency to the output side of a semiconductor device and thereby detecting out any phase lack with a simple circuit structure.  
     CONSTITUTION: A reactor 13 and a condenser 14 constitute a serial serial resonance circuit, which is set to synchronize with the frequency six times as high as the frequency of power sources R,S and T. The output of a thyristor convertor 5 normally includes a ripple current having a frequency six times as high as the source frequency, which current energizes a trouble detecting relay 15. When phase lacks occur, the frequency of the ripple current is lowered to the one twice as high as the source frequency. Accordingly, the trouble detecting relay 15 is deenergized for stopping an elevator cage 9.

Title: Device for removing forming matter of food
Inventor: FUKUDA NORIAKI
IPC: A23L5/20
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To hygienically remove foreign matter of food by heating the food with direct flames in the state of the food suspended in the space to burn the foreign matter included in the food, then sieving off the foreign matter at the time when the food under transportation falls downward in a difference-in-level section. SOLUTION: The food 12 is dropped to the transporting plate 15 side of the next stage section by the difference-on-level section connected to the terminals section of the transporting plate 13. The food 12 under falling comes into contact in the bare suspended state with the flames F ejected horizontally from the oblong fire nozzle 27 of a gas burner 21 and, therefore, the lightweight foreign matter of relatively extremely low specific heat included in the food 12 is instantaneously and efficiently burned. The waste after incineration included in a wire net 16 section is sieved and separated by vibration. As a result, the need for labor for drying, such as in the case of a wet process, is obviated as this process is a dry process. Since the removal of the waste after the incineration is made easy by a discharging means, the device is hygienic and the reduction of the size is made possible. Further, the high treatment efficiency is exhibited inexpensively.

Title: Method of cleaning surface of silicon single crystal substrate
Inventor: ITO TAIZO
IPC: H01L21/322
Filed: 1988-03-25
Abstract: PURPOSE:To obtain a highly pure and defect-free active layer region, by thermally oxidizing the surface of a silicon single crystal substrate and removing the oxide film together with the surface of a silicon layer adjacent thereto. CONSTITUTION:Conditions of thermal oxidation are optimized to produce an oxide film. The surface layer including this oxide film is removed slightly to clean the surface. The conditions of thermal oxidation may be determined, for example, such that oxidation is performed within atmosphere of 900-1200 deg.C for an appropriate period of time selected from 1 to 20hours. The substrate should have an oxygen concentration at least of 10<16>atoms/cm<3> or over and is previously heat treated within atmosphere of 600-800 deg.C. Since Fe captured at the interface between the oxide film and silicon is possibly redistributed into the substrate at a high temperature, the silicon layer may be removed by several mum from the surface simultaneously with removal of the oxide film by means of mixture of hydrofluoric acid and nitric acid solutions. In this manner, Fe in the bulk of the substrate can be removed effectively in combination with the intrinsic getter technique, so that an ideal active layer which is highly pure and free of defects can be obtained on the surface of the substrate.
