Title: Injection molding device and injection speed control method
Inventor: USHIKI YOJI
IPC: B29C45/77
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To provide an injection molding device and an injection speed control method which avoid the generation of flashes, eliminate the necessity of a large injection molding device and lower the product cost thereof. SOLUTION: When a screw 48 is slid inside a cylinder 42 and molten resin is injected into a cavity 30, a second mold 24 is displaced to a first mold 22 by the pressure of molten resin. The position of the screw 18 is measured by a position sensor 58, and the injection speed vn stored in a memory 82 from a screw position signal (c) is compared with the injection speed vp computed by a PID computing circuit 74 from the separation interval (a) and a parting face 38 measured by a distance sensor 36 and a parting face 40a by a CPU 72, and a changeover switch 76 is changed over and a signal of injection speed of either the injection speed vn or injection speed vp whichever smaller is output, and input into a flow rate control valve 86 through an amplifier 84.  The moving speed of the screw 48, therefore, is varied in compliance with the injection speed vn or vp to control the injection speed.

IPC: H01L21/8222
Filed: 1993-12-09
Abstract: PURPOSE:To form oxide films of different film thicknesses in one oxidation process by varying the introduction concentration of impurities. CONSTITUTION:The surface of a standard-withstand voltage transistor formation region 3A is covered with a resist 10. In succession, boron is introduced, by making use of the resist 10 as a mask, only into a high-withstand voltage- transistor formation region 3B in which a silicon face has been exposed. After that, the resist 10 is removed, and a wafer is wet-oxidized. Then, a thin gate oxide film 11A is formed in the boron-undoped standard-withstand voltage- transistor formation region 3A, and a gate oxide film 11B whose film thickness is thick is formed in the boron-doped high-withstand voltage-transistor formation region 3B. Since the gate oxide films 11A, 11B with different thicknesses can be formed simultaneously in one oxidation process, the number of processes can be reduced as compared with conventional cases.

IPC: C02F1/32
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to heat bathwater economically in case its temperature drops during the hours when late-night power is not available by providing a heating device to heat water in a hot water storage tank by late-night power and a mixing device to produce bath water of appropriate warmth. SOLUTION: A hot water storage tank 8 is composed of a tank 8a and a heating device 10 fitted inside it, and is also fitted with a temperature sensor which switches on/off the heating device 10 to regulate the temperature of bath water to keep it at a desired pre-set level. While, within a desired pre-set range of temperature, the bathwater is made to circulate through a purifying device and a circulatory duct 4 with a solenoid valve V remaining closed. When the temperature sensor 21 detects a drop in the temperature of the water in a bathtub 5, a valve control device 22 signals the solenoid valve V to open, which thereupon opens and lets the bathwater flow into the hot water storage tank through an inbound circulatory duct 12.  Then, water stored in the hot water storage tank 8 flows into a mixing device 13 via an outbound circulatory duct 11 and mixes with the main body of the bathwater circulating through the circulatory duct 4, thus raising the temperature of the bathwater in the bathtub 5.

Abstract: PROBLEM TO BE SOLVED: To quickly detect a jam caused from the winding of a paper-like medium on a heating roller by measuring the surface temp. of the heating roller and detecting the occurrence of the jam from a sudden change in the detected temperature data. SOLUTION: A temperature detecting means is provided with a temperature sensor 82 for acquiring temperature data, to calculate average temperature data or moving average temperature data, based on the temperature data. When the temperature sensor 82 comes into contact with the heating roller 24, the sensor 82 acquires the temperature data of the surface temp. of the heating roller 24. But, when the sensor 82 comes into contact with a jammed paper wound on the heating roller 24, the sensor 82 acquires the temperature data of the surface temp. of the paper. A temperature sudden change detecting means calculates a temperature gradient, based on the average temperature data or moving average temperature data obtained by the temperature detecting means.  When the absolute value of the temperature gradient exceeds a previously fixed allowable value, the sudden change in the temperature, that is, the jam caused by the winding of the paper on the heating roller 24 is detected.
