Title: Electrical furnace control apparatus
Inventor: NAKANO MINORU
IPC: H01L21/22
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To realize compatibility between economy and heater control in each semiconductor manufacturing step, by preparing a plurality of thyristor control systems and switching these systems therebetween for each step. SOLUTION: Power to be supplied to a heater 15 is determined by a temperature control circuit 21 on the basis of an in-furnace temperature and a heater temperature and controlled by a thyristor circuit 19. A plurality of control signal generation means for applying a gate signal to the thyristor circuit 19 are prepared to be switched therebetween by a switch means 37. The control signal generation means includes a zero-crossing control signal generation means and time-division dispersion zero- crossing control signal generation means 35 and 36 for turning ON and OFF an A.C. power alternately at each one cycle of the power or at each half cycle thereof.  According to the switching, an execution step requiring a stable temperature state selects phase control, an initial and later stable step selects zero-crossing control to realize an economical efficiency, a temperature raising step in a semi-execution process state selects semi-period time-division dispersion zero-crossing control reasonable in economical efficiency and control performance, and a lowering temperature step selects one- period time-division dispersion zero-crossing control allowing a slightly increased economical efficiency.

IPC: H04N5/76
Filed: 1989-09-25
Abstract: PURPOSE:To prevent the deterioration of the quality of an output image for a long time by adjusting the driving signal of a cathode ray tube based on the data of a counter which counts the number of exposed sheets corresponding to the total light emitting time of the cathode ray tube when exposure is performed on a photosensitive recording medium. CONSTITUTION:The device is provided with the counter 20 which counts the number of exposed sheets corresponding to the total light emitting time of the cathode ray tube when the exposure is performed on the photosensitive recording medium 6 and a brightness adjusting device 2 which adjusts the driving signal of the cathode ray tube 4 based on the data of the counter 20. When the data of the number of exposed sheets counted by the counter 2 attains a certain value, the driving signal in the cathode ray tube 4 is adjusted. Namely, the brightness is lowered and the cathode ray tube gets dark in the case of using the casthode ray tube for a long time, so that the driving signal is successively adjusted in accordance with the number of exposed sheets corresponding to the total light emitting time of the cathode ray tube 4 so as to control to make the cathode ray tube bright. Thus, the lowering of the brightness is compensated and the deterioration of the quality of the output image is prevented in using the device for a long time.

Title: Method and apparatus for estimating speed of inverter device motor and vector controller of motor using the same method
Inventor: TOBARI KAZUAKI
IPC: H02P23/07
Filed: 1992-09-18
Abstract: PURPOSE:To enhance a response speed 4 estimating and controlling speed. CONSTITUTION:An output frequency command value Vq* is input, and a value Vq' corresponding to a q-shaft voltage command value Vq* is obtained by a q-shaft voltage command calculator 12a. The detected value Iq of a q-shaft current component is input, and a leakage impedance voltage drop due to the q-shaft current of an induction motor is obtained by a voltage drop calculator 12b. The difference between the voltage drop and Vq' by a subtracter 12c is obtained as a speed electromotive force estimated value E'. The value E' is converted into a speed estimated value omega' by a speed converter 12d. Thus, since a speed control system is separated from a current control system to estimate the speed of a motor, the response speed of speed estimation can be arbitrarily enhanced, and since response speeds of the speed control system and the current control system can be set separately from the speed estimation, the speed control of high response speed can be realized.

Filed: 1991-09-27
Abstract: PURPOSE:To prevent amalgam encapsulated in a thin tube of a fluorescent lamp. from separating off even when it is lighted up in a high temp. atmosphere and eliminate blackening of a light emitting bulb by specifying the Hg, Bi, Sn composition of the amalgam. CONSTITUTION:An amalgam 2 encapsulated in a thin tube 4 of the stem 3 of a fluorescent lamp 21 is formed from a Hg alloy with Bi and Sn containing 10% or more by weight Hg. If the ratio of Bi by weight to the total weight of Bi and Sn is set below 35% or over 70%, the melting point of the amalgam 2 can be made over 160 deg.C. Therefore, the amalgam 2 can be prevented from separating off into light emitting bulbs 22a, 22b upon passing through a throat 11 of the thin tube 4 even though the lamp 21 is lighted up to cause the ambient temp. to get high. This prevents amalgam attachment to the inner surface of the light emitting bulb and eliminates risk of its blackening.
