Title: Polysilicon etching device for semiconductor element manufacture
Inventor: SHON YORU MUN
IPC: C23F4/00
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To decrease contamination of a wafer due to a polymer by a method, wherein a polysilicon etching device is constituted in such a structure that a vacuum pump is disposed on the side lower than a fluid path, which exhausts reactions gas through a reaction chamber provided with a wafer chuck for loading the wafer, and at the same time, cleaning gas can be injected in the reaction chamber. SOLUTION: A polysilicon film on the surface of a wafer is etched, and thereafter, a vacuum pump 7 is actuated. At the same time, He gas is fed through a cleaning gas feeding line 8 into the initiator of a reaction chamber 3. The internal pressure in the chamber 3 before and after an etching process is made almost equal with the pressure in the chamber 3 under the etching process and a fall of a polymer and the inflow of a foreign substrate from the load lock of a standby chamber for the wafer 2 are also minimized. When the etching process ends, the injection of the He gas and a pumping radiation are executed simultaneously, to conduct efficient cleaning of the interior of the chamber 3, the pump 7 is put on the side lower than a fluid path to facilitate a pumping and when the pump 7 is stopped, the inflow of the polymer is suppressed.  As a result, contamination of the wafer due to the polymer is decreased, and the yield of a semiconductor element is enhanced.

IPC: F02M57/02
Filed: 1987-09-29
Abstract: PURPOSE:To stabilize the control of fuel injection by actuating a piezoelectric element controlling the fuel pressure within a hydraulic chamber in a crank angle zone wherein no fuel injection is processed, and preventing fuel pressure from fluctuating before fuel injection. CONSTITUTION:When a plunger 17 is lowered depending on a cam 22 driven by an engine, a fuel feed port 25 is closed, fuel within a fuel force feeding chamber 18 flows out into a fuel downtake chamber 23a through both a passage 32 and a circular groove 30 of a sliding valve 28. A piezoelectric element 41 is energized at the time of fuel injection so as to let a piston 40 be displaced to the left. The pressure within a hydraulic chamber 42 is increased instantly so as to close the sliding valve 28 via a rod 37 for injecting fuel. An electronic control unit 50 controlling an unit injector 1 concerned actuates the piezoelectric element 41 based on the detected value from a crank angle sensor 61 when the plunger 17 is in a position ready to compression, thereby lowering the fuel pressure within the hydraulic chamber 42 for preventing erroneous injection.

Title: Discharge point detecting method in electric discharge machining and electric discharge machining control method using the above
Inventor: KUNIEDA MASANORI
IPC: B23H1/02
Filed: 1989-09-21
Abstract: PURPOSE:To detect the position of a discharge point using an ordinary discharge machining electrode while actually carrying out electric discharge machining, at the time of electric discharge machining, by detecting respective current values passing through respective branch feed lines so as to obtain the position of the discharge point from the respective current values. CONSTITUTION:When a current is fed to an electrode 12 from several points and electric discharge is caused between the electrode and a work 11, since the length of current flow passage inside the electrode 12 differs in accordance with the distances from respective feed points A, B, and C to the electric discharge point, the resistance values from respective feed points A, B, and C to the electric discharge point also differ. As a result, a difference in the current values passing through respective branch feed lines 15 is caused according to the position of the discharge point. Thus, by detecting the respective current values by means of a current sensor 16, the position of discharge point can be obtained.

IPC: G01R22/00
Filed: 1987-09-30
Abstract: PURPOSE:To prevent a function from stopping even in an open-phase state and to detect even the open-phase by connecting one-terminal side of two single- phase power transformers in common as a three-phase AC input and connecting the secondary sides in common through diodes respectively. CONSTITUTION:Normally, when respective phase voltages of P1, P2, and P3 phases are supplied, a sufficiently high DC voltage is developed across a capaci tor 10 for rectification by a full-wave rectifying circuit from the single-phase power transformers 4 and 5 and applied to an electronic watthour meter 20 through a three-terminal regulator 11. If one phase is open, the voltage across the capacitor 10 drops to a half, but a constant current is supplied to the watt hour meter 20 and an open-phase detection part 30 by the regulator 11. Then the detection part 30 compares voltage signals PH1 and PH3 with a reference voltage -VR by comparators 33 and 34, whose output pulses are passed through binary counters 38-40 and FFs 41-43 to obtain open-phase signals theta1, theta2 and theta3. Then those open-phase signals are combined to discriminate an open-phase, and consequently the function does not stop in an open-phase state and even the open-phase is detected.

Abstract: PURPOSE:To perform normally stable high temperature combustion and melting, by a method wherein an unburnt substance remaining in incineration ash is burnt in incineration ash, a content of the unburnt substance is determined from generated melting gas and oxygen concentration, and melting is effected in a way that air feed amount is regulated to a value corresponding to the content. CONSTITUTION:Incineration ash A conveyed in a melting furnace 2 is orderly burnt and melted on a furnace floor part 5. In this case, the temperature of melting gas generated along with combustion and oxygen concentration are detected. From the oxygen concentration, a computing unit 18 calculates an air excess factor (air ratio). From temperature detected based on a relational diagram, a current unburnt carbon content is determined, and an air feed amount corresponding to the unburnt carbon content is determined. An air amount control device 20 regulates an air feed means so that a difference between an air feed amount judged by the computing unit 18 and a detected air amount is eliminated. Thus, an air amount corresponding to a residual unburnt carbon in the incineration ash A is fed to an ash melting furnace 2, which can effect stable high temperature combustion and melting.
