Filed: 1986-11-07
Abstract: PURPOSE:To easily and efficiently obtain the title high-purity zinc white with less energy to be used by mixing a specified dead-roasted material with coke as the reducing agent, heating the mixture to obtain metallic zinc vapor, and reoxidizing the vapor in a furnace. CONSTITUTION:The steel making flue dust is charged in a first-stage rotary heating kiln 3 without adding an additive to the dust and dead-roasted at 800-1,100 deg.C for about 1hr to selectively volatilize Pb, Cd, and Cl, and the obtained volatiles are recovered in a first-stage recovery device 5. Meanwhile, the nonvolatile Zn and Fe components are left as ZnO and Fe2O3, and the obtained dead-roasted material (A) is collected from an outlet 3b. About 30wt% coke as the reducing agent is then added to the A component, the mixture is charged into a second-stage heating kiln 6 and heated at 900-1,100 deg.C for about 1hr, hence the ZnO in the A component is transiently reduced, and the formed metal Zn vapor (B) is volatilized. The B component is reoxidized by heated air and sent into a second-stage recovery device 8 through a duct 7, and zinc white is obtained from the steel making flue dust.

IPC: B60L13/06
Filed: 1985-11-26
Abstract: PURPOSE:To reduce power consumption by further adding a signal representing the integrated value of a current flowing to a coil to the sum of the signal of a displacement sensor and the differentiated signal. CONSTITUTION:A gap 6 between a movable unit 5 and a magnet 1 is detected by a displacement sensor 7. A current flowing to a coil 4 is detected by a current detector 25, and integrated by an integrator 26. A signal E1 representing a gap variation of the output signal of the sensor 7, a signal E2 representing a speed of the output signal of a differentiator 9 and a signal E3 representing the integrated value of the current flowing to the coil 4 of the output signal of the integrator 26 are applied to an adder 10. The output of the adder 10 is supplied through a power amplifier 11 to the coil 4. Thus, even if an external force is not acted on the movable unit, when a time is elapsed, a coil current is converged to zero, thereby reducing the power consumption.

Title: Fuel injection nozzle
Inventor: YODA TOSHIYUKI
IPC: F02M61/16
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection nozzle in which the injection angle of the fuel is variable. SOLUTION: Since the third spring 71 housed in the third spring housing room 70 urges a swirler 60 to the anti-injection hole side, the swirler 60 is moved to an injection hole 12 side against the urging force of the third spring 71 by a fuel pressure fed in a nozzle body 11. As a result, by reducing the height and the volume of a swirl chamber 90 following to the increase of the fuel injection pressure in a high speed and high load time, the injection angle is made large, and the reaching distance is made small in the high speed and high load time. Consequently, a desired injection angle and a desired reaching distance of the injection can be obtained, by changing the swirling strength according to the load condition of an engine.  Furthermore, since the injection angle and the reaching distance can be set to the fuel injection pressure by changing the pressure receiving surface of the swirler 60, the spring constant of the third spring 71, and the setting load, the fuel injection nozzle can be responded to the fuel injection valves for various types of engines simply.

Filed: 1993-10-22
Abstract: PURPOSE:To provide the gate circuit of an IGBT and a GTR which does not turn on the IGBT and the GTR at the time of turning off a power source. CONSTITUTION:In the gate circuit of an IGBT and a GTR where the bipolarity power source obtained from the rectifier circuit 3 connected with the secondary side of a transducer 2 is made a power source, the control signal of the IGBT or the GTR becomes off when the power source is turned off and the gate voltage of the IGBT or the GTR becomes minus voltage because the bipolarity power source is connected with each capacitor 41 and 42 and the capacitance connected with the plus side of the power source is made smaller than the capacitance connected with the minus side and the voltage on the side of the plus becomes zero first because the resistance value or the capacitance on the plus side of the bipolarity power source is smaller than the resistance value or the capacitance on the minus side. Therefore, plus voltage is not impressed on the gate of the IGBT or GTR when the power source is turned off.

Filed: 1985-11-25
Abstract: PURPOSE:To make an airtight failure between cells preventable, by installing an air hole in a heating plate to be used in a heat deposition process between a battery jar and a cover. CONSTITUTION:In a heating plate 1, an air hole 1 is opened in a part corresponding to each cell avoiding a spot where a partition wall 3 of a battery jar 1 comes into contact with a partition wall 3' of a cover 4 and another part intersecting the former, whereby the plate 1 is interconnected to the atmosphere. When heat deposition between the battery jar 2 and the cover 4 is carried out with the heating plate 1, the battery jar 2 and the cover 4 are pressed to the heating plate 1. At this time the heating plate 1 comes into contact with the battery jar 2, producing a melting layer of resin, thus it hermetically seals an interval between the heating plate 1 and the battery jar 2. And, air inside the battery jar is heated and expanded by the heating plate 1 and escapes to the atmosphere from the air hole 5. Therefore, an airtight failure between cells caused by a bend of the partition wall 3 due to a pressure differential between cells of the battery jar 2 is reducible.
