Title: Induction motor controller of elevator
Inventor: MITSUI SHIYUUZOU
IPC: H02M7/48
Filed: 1984-03-28
Abstract: PURPOSE:To prevent an overcurrent from flowing to a converter by initially driving a converter and driving an inverter after the elapse of minute time length. CONSTITUTION:A speed controller 13 inputs a speed command 21, a balance signal 22 which detects a load in a cage, and a cage speed signal 23, calculates a speed command, and outputs a current command 24 and a voltage command 25 to an inverter drive unit 25 and a converter drive unit 16. If converter and inverter operation enable signals 34 are input from a controller when an elevator is started, an interruption signal generator 14 first releases the gate interruption signal 32 of the converter, then releases the base interruption signal 33 of the inverter after the short time is elapsed. Since the signal 32 is already released to control the operation of the converter when the signal 33 for controlling the operation of the inverter is released, no overcurrent is flowed to the converter.

Title: Electrooptical modulating element, driving method and driving circuit for this element and electrooptical modulating device
Inventor: NAGATA TETSUYA
IPC: G02F1/133
Filed: 1989-03-13
Abstract: PURPOSE:To obtain a high contrast with a low driving voltage by impressing an AC voltage of such a high frequency at which the response of an electrooptical modulating material in correspondence to the polarity of the impressed voltage cannot follow up after the DC voltage pulses for putting picture elements into a desired state are impressed during a selection period. CONSTITUTION:The DC voltage pulses 14 are impressed to the ferroelectric liquid crystal molecules 7 existing in a position 12b. The high-frequency AC voltage 15 symmetrical with positive and negative is then impressed right after at least the state exceeding the position 12c is attained even if the response is not perfect. If the ferroelectric liquid crystal molecules 7 have negative dielectric anisotropy, the dielectric torque 16 by this AC voltage acts to put the liquid crystal molecules 7 into the state perpendicular to the direction of the impressed voltage, i.e. to put the liquid crystal molecules 7 into the state parallel with a glass substrate 2. The ferroelectric liquid crystal molecules 7 eventually arrive at the position 12a and the response is completed. The high contrast is obtd. with the low driving voltage in this way.

IPC: H03K17/73
Filed: 1985-03-25
Abstract: PURPOSE:To provide a semiconductor switching circuit with current limiting action so that an electric current can make self-turning off before it becomes a chip destructing current of a thyristor, etc., by operating a short-circuiting means provided between the gate and cathode of the thyristor by actuating an amplifying means by using the output of a current detecting means. CONSTITUTION:An electric current IK is made to flow to a resistor 9 under a normal 'ON' condition of a thyristor, but, when the built-in voltage between the base and emitter of an npn transistor 10 is set at a value VBF(10) and the value of the resistor 9 is set at RK, the npn transistor 10 is not turned on and the 'ON' condition of the thyristor continues under a condition where IKXRK <VBF(10). When the IK increases, namely, when an overcurrent is made to flow and a condition, IKXRK>=VBF(10), is set, the npn transistor 10 is turned on because the base current is made to flow. As a result, another npn transistor 11 is further turned on and the collector current of the transistor 11 becomes the base current of an npn transistor 8 and short-circuits the P-gate terminal 3 and cathode terminal 2 of the thyristor. Accordingly, the thyristor is immediately turned off.

Title: Protective circuit for transmission tube
Inventor: MASUNO YOSHIKI
IPC: H04B1/04
Filed: 1981-04-21
Abstract: PURPOSE:To prevent the breakdown of a transmission tube by employing a high resistance and a diode to increase the anode voltage of a switching tube during the shortcircuit of the transmission tube thereby functioning the switching tube without fail. CONSTITUTION:When the inner shortcircuit has occurred in a transmission tube 6, the large current will flow through the transmission tube 6 from a high voltage D.C. power source 1 through the resistors 3, 4. Here the current is fed through a current transformer 8 to the drive circuit 7, and if the current level is abnormally high when compared with the normal level it is decided that the shortcircuit has occurred in the transmission tube 6 to provide the drive trigger to a switching tube 6. Here the switching tube 5 will first conduct from the high voltage D.C. power source 1 through a high resistance R3. The current is low because of the high resistance R3 but the majority of the large current flowing through the transmission tube 6 because of the conduction through the current limiting rsistance 3 of the switching tube 5 will flow through the switching tube 5 thereby the transmission tube 6 is protected.
