Title: Electrostatic discharge device
Inventor: EGAMI HIDEMI
IPC: G03G15/02
Filed: 1986-07-11
Abstract: PURPOSE:To immediately and efficiently execute uniform and stable electrostatic discharge by providing the titled device with a means for impressing a voltage a discharge start voltage between an inductive electrode and a discharge electrode before the start of discharge operation and a means for heating near the discharge electrode. CONSTITUTION:In case of electrostatically charging a body 2 to be charged by using a discharge member 1, a heating power supply 8 is turned on before the charging operation and the discharge electrode 5 to be used also as a heating resistor is heated by resisting loss due to heating current. Simultaneously with the heat generation of the electrode 5, AC voltage is impressed from an AD high voltage power supplied to the electrodes 4, 5 and the value of the AC voltage is set up to a value less than a discharge start voltage by a voltage control device 7a, so that heat generation due to induced loss is generated. Temperature near the electrode 5 is detected by a temperature detecting element 13, the current value of the power supply 8 is controlled by a temperature control device 14 and the temperature around the electrode 5 is kept at an optimum value for discharge. Consequently, water in the dielectric body arranged near the discharge electrode 5 is evaporated and stable and uniform discharge can be attained.

Title: Low magnetic forming roll with resistance to wear and thermal impulse
Inventor: OKUNO TOSHIO
IPC: C21D9/38
Filed: 1980-11-20
Abstract: PURPOSE: To obtain a forming roll improved in the energy effect, line rate and roll performance, by carring out suitable heat treatment on a high C and high Cr steel for a roll to reduce the magnetism.  
     CONSTITUTION: A high C and high Cr steel is used for a roll, and it is subjected to suitable high temperature hardening to permit residual austenite of 20% or more to remain. Thus the magnetism is reduced as a whole, and therefore under the influence of high frequency magnetic field for heating a joining section of a steel pipe from a steel sheet, the elevation of temperature and energy loss due to the induction of the roll itself can be decreased. Generally, the quenching will be carried at about 1,080W1,250°C, and the cooling is carried out by controlled quenching such as cooling in oil, hot bath quenching or the like, but the risk of decomposition of the austenite during cooling is less due to the austenite stabilized by heating at high temperature. The aimed amount of residual austenite can be provided by controlling the heating temperature of quenching, the retention of the time and the cooling rate. Since said decomposition is accompanied when tempered, the tempering should be about 500°C or below, but the change in the hardness due to it is not significant.

Filed: 1980-11-20
Abstract: PURPOSE:To promote light-sensibility by a method in which a mixed film of SiO2 and Si3N4 is deposited on a light sensitive region on a semiconductor substrate, and light reflection factor is minimized by meeting a condition of n1  n0<0.5> when a refrective index of light in the substrate is n0 or that in the mixed film is n1. CONSTITUTION:A P type region 2 is formed by diffusion through a mask 3 of a specified pattern on an N type substrate of silicon chip 1 to produce a P-N or a P-I-N junction. Next, the mixed film 4 of SiO2 and Si3N4 is deposited on the entire surface including the light sensitive region 2, and a window is opened on the film to provide an access electrode 5 on the region 2. In such construction, mixing ratio of materials for the film 4 is to be n1 n0<0.5> when the refractive index of light in the substrate 1 is n0 and that in the mixed film 4 is n1. In other words, SiH4, NH3, O2 and N2 are put in a reaction furnace in a ratio 0.3:2:0.2:100 in order to deposit the film 4 by the plasma CVD method. Thus, the refractive index of light n1 in the film 4 can be made to be approximately a value of 1.9, and that of n0 in the substrate 1 to be a value of 3.42<0.5> which is nearly the same value as the former.

Filed: 1984-08-07
Abstract: PURPOSE:To prevent the fuel clogging due to icing by dividing the bleed air of a variable venturi type carburetor into two systems and controlling the flow rate according to water temperature in one system and controlling the bleed air by an opening/closing valve in the other and supplying the both bleed air into fuel through a common chamber. CONSTITUTION:A needle valve 4 is fixed at the edge surface of a slidable piston installed onto the upstream side of a throttle valve 6. The amount of fuel supply is controlled by the gap between the needle 4 and a jet 21. Bleed air is supplied into the jet 21 part through a hole 25, and the bleed air is supplied from two systems of the holes 26 and 27. When engine temperature is low, the hole 34 of a wax 32 is throttled by a valve 33 according to the cooling-water temperature, and air is supplied according to the rise of the water temperature, and since the amount of air is little, icing is generated at the hole 25 part, and also the jet is closed. In this case, air is supplied from the hole 27 by opening a valve 40, and the air is mixed in a common chamber 24, and icing is prevented and the mixed gas is made thin.
