Title: Waste gas treating part in vapor growth device and operation thereof
Inventor: KOMURA YUKIO
IPC: H01L21/205
Filed: 1988-02-08
Abstract: PURPOSE:To facilitate the leakage check of an exhaust tube and insure safety during the exhaust suspension of waste gas as well, by connecting first and second high pressure valves to parts of both side exhaust tubes in a waste gas treating equipment, thereby always supplying an inactive gas to the exhaust tube. CONSTITUTION:On the occasion of a leakage check, an inactive gas N2 is fed to an exhaust tube 31 located between high pressure valves 34 and 35 as well as to a waste gas treating equipment 32 after closing the first and second high pressure valves 34 and 35 and yet, after opening auxiliary valves 36 and 37 as well as a valve 42 of an inactive gas supply means 39 and then, the above elements are pressurized to be in a state of high pressure. After recognizing such a pressure by a pressure gage 38, the valves 42, 36, and 37 are closed. After permitting such a high pressure to stand for 24 hours, it is confirmed whether an indication of the pressure gage 38 moves or not. Similarly, the leakage check of the gage is carried out by observing the lowering of a pressure indication at each section between the valves, while extending the section of checking by opening the valves in the order of auxiliary valves 36 and 37. The inactive gas N2 is always supplied to the exhaust tube 31 by the inactive gas supply means 39 even during the exhaust suspension of the gas discharged by a vapor growth disposition part 3. As a result, the entrance of the air into the exhaust tube is prevented by purging always from the waste gas treating equipment 32 to an exhaust blower 33.

Title: Flame whirling type low nox combustion device
Inventor: TSUMURA SHIYUNICHI
IPC: F23D11/00
Filed: 1982-02-22
Abstract: PURPOSE:To lower the amount of NOx, by arranging burners so that a main burner flame and flames containing intermediate products might be whirled. CONSTITUTION:In a main burner, the combustion air 10 is supplied with the air/fuel ratio being 1 or more. In this case, the combustion air 10 is provided with a whirling force by an air register 6 arranged in a wind box 7 and the main burner is suitably positioned so that the main burner flame is provided with a powerful whirling force. In a reducing burner 2, fuel is jetted with the air/fuel ratio being very low or without the supply of air. The thus jetted fuel forms a whirling stream in the opposite direction since the reducing burner 2 is opened slantly in a direction opposite to the case of the main burner 1, and the fuel is burnt with oxygen remaining in the combustion chamber to perform low O2 combustion. Accordingly, NOx can be eliminated without making the combustion unstable nor increasing unburnt amount of the fuel.

Title: Limiter circuit
Inventor: KIDA SUMIO
IPC: H03G11/00
Filed: 1988-02-05
Abstract: PURPOSE:To remove the asymmetry of an output waveform when a VBEN and a VBEP are different by causing the reference voltage of an input signal to be dependent on a difference between the on-voltages VBEN and VBEP between the bases and emitters of NPN and PNP transistors Trs. CONSTITUTION:When voltages between the bases and emitters of Trs Q3 and Q4 are made into the VBEN and VBEP, an output dc voltage VREF can be expressed by an expression I. When the on-voltages between the bases and emitters of Trs Q1 and Q2 are equal to the VBEN and VBEP, respectively, a clip voltage VU of an upper half wave and a clip voltage VD of a lower half wave can be expressed by expressions II and III, respectively. Consequently, from the expressions I...III, a difference between the upper and lower half clip voltages is made into an expression IV and 0, and the difference between the voltages between the bases and emitters of the NPNTr Q1 and PNPTr Q2 does not appear at an output terminal 4. Simultaneously, the clip voltages VU and VD can be adjusted by changing variable voltage sources V1 and V2, respectively.

Title: Thin film magnetic head
Inventor: KOMAKI KENJI
IPC: G01R33/035
Filed: 1988-02-05
Abstract: PURPOSE:To miniaturize a device and to make it light weight by heightening saturation magnetic flux density by providing an electrode to output a voltage generated by stress sensed by a piezoelectric thin film to an external circuit on a laminate body. CONSTITUTION:Since a superconductor layer 1 repulses so as to prevent a magnetic flux B from being inputted to its inside by a Meissner effect when the superconductor layer 1 passes through the magnetic field B from a magnetized magnetic tape 7, repulsion F is generated on the surface of the superconductor layer 1, and the repulsion F is applied as the stress on a piezoelectric layer 2, and electric charge Q is generated on the surface of the piezoelectric layer 2. Potential difference V between both sides of the piezoelectric layer 2 generated by the electrical charge Q is outputted from electrode layers 3 and 4 to the external circuit as a voltage signal. Since the outputted voltage V is proportional to the repulsion F that is the stress for the piezoelectric layer 2, and the repulsion f is proportional to the square of the magnetic strength of the magnetic flux B, the voltage V is proportionated to the square of the magnetic flux strength. Therefore, it is enough to perform a differential processing on a signal outputted as the voltage to detect the magnetic strength of the magnetic flux B. Thus, it is possible to miniaturize the device and to make it light weight.

Filed: 1993-02-16
Abstract: PURPOSE:To lessen aerodynamic interference of rotors by disposing both a front and a rear rotor offset from the senter line of the fuselage and rotating both the rotors in mutually opposite directions. CONSTITUTION:A front rotor 23A and a rear rotor 23B are disposed offset, right and left, front the center line 29 of the fuselage, so that aerodynamic interference between the front and the rear rotor is lessened, thereby possibly improving the helicopter performance. Further, since moment of intertia around the front and the rear axis in the helicopter is increased, the influence by side wind is decreased, so that the flight characteristic is improved. Then, the fuselage can be widened right and left and be shortened back and forth, and thus the helicopter becomes compact overall. Rotation of the front rotor 23A and of the rear rotor 32B are in mutually opposite direction, so that the rotor torque are mutually canceled.

Abstract: PURPOSE:To carry out automatic and continuous hardening work with a conveyor and to improve the efficiency by dividing an induction heating coil into upper and under conductors so that the conductors can be brought into press contact with each other and can be separated and by heating only ends of each curved member. CONSTITUTION:An induction heating coil 5 having its axis in the horizontal direction is horizontally divided into an upper conductor 5a and an lower conductor 5b so that the conductors 5a, 5b can be brought into press contact with each other and can be separated repeatedly. When the conductors 5a, 5b are brought into press contact with each other, a curved member 3 only ends 3a, 3b of which are to be hardened is put in the coil 5, and the ends are heated. When the member 3 is sent out, the part other than the ends is passed through the space between the conductors 5a, 5b and by the coil 5. Thus, hardening is carried out by continuous work with a conveyor.

Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus and a method by which various operating modes of a measured-value converter are changed over surely by installing a comparison unit by which a signal to be output a signal transmission conductor is compared with a reference signal and by which an operating mode at this time is discriminated. SOLUTION: The signal of a measured-value generation unit 5 at a measured- value converter 1 is transmitted to a succeeding processing unit 2 via two signal transmission conductors 3, 4. A comparison unit 7 continuously detects the signal which is transmitted and output via at least one out of the signal transmission conductors 3, 4. The detected signal is compared with a prescribed reference signal by the comparison unit 7. As a result, an operating mode which is operated at this time is discriminated. According to the type of the transmitted signal, the comparison unit 7 operates corresponding changeover means 8.1, 8.2 in order to change over the operating mode. Therefore, various operating modes of the measured-value converter 1 can be changed over surely, and the processing unit 2 can be matched simply to a specific parameter.

Title: Anti-runaway circuit for inverter
Inventor: OSAWA HISAHIRO
IPC: H02P27/06
Filed: 1991-01-28
Abstract: PURPOSE:To prevent runaway by deciding discontinuity based on a variation of detection level of a current detector connected from a speed setting reference power supply through a speed setter to a proper point on the inverter side of a conduction circuit grounded on the inverter side. CONSTITUTION:A current detector 4 comprises a photo MOS relay and turned OFF when a detected current is lower than a threshold level. When a power supply reference line connected between terminals 12, 9 is cut at point P, current I1 goes substantially to zero. Consequently, current detection level of the current detector 4 drops below the threshold level and a switch is turned OFF. The OFF state is detected through a discontinuity decision circuit 6 which then provides a discontinuity signal to a control circuit 2. Upon receiving the discontinuity signal, the control circuit 2 stops the motor. When the power supply reference line is cut between terminals 5, 11, current I1 goes to zero and the zero current state is detected through the current detector 4.

Filed: 1985-02-14
Abstract: PURPOSE:To measure the characteristic of deflection yoke accurately and easily by providing a measuring yoke for catching the magnetic field produced by A.C. current flowing through the deflection coil and a device for measuring the currents flowing through the deflection coil and induced in the measuring coil. CONSTITUTION:Flux 13 is produced in the core 12 by A.C. current flowing through a deflection coil 8 to induce a voltage across a coil 9. While the current flowing through the deflection coil 8 will induce a voltage across a resistor 7. Since the voltage induced across the coil 9 is the differential of flux produced by the current flowing through the deflection coil 8, the output voltage of an integrator 10 has same shape with the flux produced by the deflection coil 8. Consequently, deflection current is inputted to X-axis of oscilloscope while the flux density of deflection field is inputted to Y-axis to describe a hysteresis curve. In such a manner, the magnetic field produced through the deflection yoke can be measured accurately.
