Title: Controller for current type inverter
Inventor: KOBAYASHI TOSHIRO
IPC: H02P27/06
Filed: 1985-12-19
Abstract: PURPOSE:To cancel the reduction of motor torque without generating a commutating failure accident on an inverter when a motor is operated at a low speed, by starting auxiliary set signal for input to a voltage regulating means, gradually from zero. CONSTITUTION:When the starting of an induction motor 6 is detected by an operation/stop circuit 31, then signal is generated to an added or subtracted speed arithmetic unit 30, and the working of the arithmetic unit 30 is started. Accordingly, the value of auxiliary set signal for input to a voltage regulator 14 from an auxiliary setting device 13 via the arithmetic unit 30 is zero at the moment of starting the induction motor 6, and after that, the value of the input is gradually increased along with varied speed set by the added or subtracted speed arithmetic unit 30. Accordingly, the value of the DC intermediate circuit current of a current type inverter is also increased along with the starting gradually, and so commutating condenser voltage is also charged gradually along with the starting, and the commutating failure of the inverter is not generated.

Title: Pressure sensor
Inventor: MIYAKE KUNIAKI
IPC: G01L19/14
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To simplify the assembling process while realizing excellent heat resistance by bonding an electrode to a conductive electrode extension member and taking out an electric signal through the electrode extension member. SOLUTION: A gauge part 21 and Au electrode parts 22-25 are formed on the upper surface of a diaphragm 9 and pins 26, 27 of conductive electrode extension member are planted while being bonded to respective electrode parts and then the pin 26 is bonded to the core 34 of a lead wire 30 by welding. The thin film like upper part 11 of the diaphragm 9 is deformed by a pressure acting on a pressure receiving part 47 to cause the deformation of strain gauges 48-51 and the resistance thereof is varied. Variation of resistance is taken out as variation of output from a bridge circuit formed by respective strain gauges. More specifically, the pressure acting on the diaphragm 9 is converted into an electric signal and amplified through the electrode extension member and the pressure is measured. Since electronic components having low heat resistant temperature, e.g. an amplifier circuit, are disposed on the outside of the body, heat resistance is enhanced, positioning id facilitated as compared with a case for connecting the lead wire directly to the electrode and the assembling process is simplified.
