Title: Automatic feeding and dividing apparatus for melted substance
Inventor: TAKADA SHIYOUTAROU
IPC: B01J4/00
Filed: 1980-06-21
Abstract: PURPOSE: To enhance the operating efficiency and the safety of the titled apparatus, by selectively regulating the valves according to the control signal for feeding the melted substance to each object, and by changing the angle of slope of the feeding path for controlling the flow speed.  
     CONSTITUTION: A raw material 12 is fed by a conveyor 11 which serves also as a stockpile stand. It is fed via a raw material hopper 14 and a chute 15 to a crucible 16 and is melted. And the raw material is added by the signal of a volumetric temperature detector 19, and the temperature is controlled by a burner 20 accordingly. When the temperature of molten metal rises to the assigned temperature, the signal from a detector 19 opens a valve A which serves also as a double safety device, and a dividing valve B for the melted substance, thus feeding it for the supplying objects of the melted substance. In case when any change of the speed and the rate of the flow is necessary, the angle of the slope and the caliber of a dividing path 25 are changed. On detecting any vibration, instantaneously with an emergency signal of the vibration detector 38, the valves A, B are shut, and also the raw material supplying inlet 17 is shut by an emergency shutter 18.

Filed: 1992-04-06
Abstract: PURPOSE:To solve a problem of a variation of a time until a conversion efficiency is varied by a power source voltage of a charging pump circuit or an output voltage becomes constant. CONSTITUTION:A constant current I1 flows to a constant-current source 9 by applying a power source voltage VDD. This current I1 is switched by current switching means 10, oscillation capacitors 21, 22 are charged and discharged, and a triangular voltage is generated from the capacitor 21. Inverters 31, 32 compare threshold voltages with the generated triangular voltage to control to turn ON, OFF an NMOS 14, thereby switching the means 10. Thus, the capacitors 21, 22 are switched to be charged and discharged, and an oscillation frequency of an oscillator becomes inversely proportional to the voltage VDD.

Title: Evaluating method of silicon single crystal
Inventor: HONDA KOUICHIROU
IPC: H01L21/322
Filed: 1981-06-01
Abstract: PURPOSE: To make it possible to judge the quality of an Si single crystal, by heat-treating the Si single crystal in an inert gas continuously at a low and a high temperatures in two steps, and measuring the concentration of oxygen reduced before and after the heat treatment.  
     CONSTITUTION: An Si single crystal is continuously heat-treated in an inert gas at a low temperature (600W800°C) and a high temperature (1,100W1,250°C) in two steps. In the process, the oxygen concentrations of the Si single crystal at the start of the heat treatment and the completion of the thereof are measured by the infrared differential spectrum method, etc. If the reduction in the oxygen concentration is ≥2×10 17 cm -3 , the single crystal is of good quality in which a denuded zone (DZ) is formed. If the reduction is less than that, the DZ is judged to be unformed. According to the method, the quality of the single crystal can be judged only by measuring the reduction in the oxygen concentration of the Si single crystal before and after the heat treatment.
