IPC: B23Q11/00
Filed: 1984-08-07
Abstract: PURPOSE:To balance weight without causing a shock, through a weight balance controller for a machine tool or the like, by detecting the kind of a replacing article, and operating a pressure regulator on the basis of a kind signal to control oil pressure to correspond to the kind. CONSTITUTION:When a workpiece in a balance weight state is replaced with a heavier workpiece W2, the kind of the workpiece W2 is detected by a limit switch 32 engaged with a dog 36, so that a kind signal is applied to a pressure regulator 38 through a sequence control circuit 30. A predetermined voltage corresponding to the kind of the workpiece W2 is sent out from the pressure regulator 38 to an oil pressure switch 46. As a result, a pressure reduction valve 50 is operated to alter oil pressure which is applied to a table 62 through a hydraulic pump 56 and a hydraulic cylinder 58 to oppose the weight of the workpiece W2. The balance of weight after workpiece replacement or the like is thus achieved quickly without causing a shock.

Title: Compensator for instantaneous reactive power
Inventor: SAWADA HIROAKI
IPC: G05F1/70
Filed: 1990-06-26
Abstract: PURPOSE:To improve the compensating ability for the higher order harmonics contained in both reactive and active currents by applying the feedforward control which is not applied to a three-phase AC coordinate system to the higher harmonic components and to an instantaneous reactive current of an instantaneous active current transformed to a two-axis coordinate system. CONSTITUTION:The basic wave component of an instantaneous active current iq is eliminated by an HPF 90 and the higher harmonic component of the current iq is detected. Then the higher harmonic component is added to a DC voltage control current command Vdc via an adder 63, and this computing result is sent to a feedforward control circuit 22 for execution of the feedforward control. Thus a compensated current command value iq* is calculated. Meanwhile an instantaneous reactive current id is sent directly to a feedforward control circuit 21 for execution of the feedforward control. Thus a compensated current command value id* is calculated. The feedforward control can not be attained in the three-phase AC coordinate system, but an effective control is attainable by applying the feedforward control to the higher harmonic components of both currents id and iq transformed in the two-axis coordinate system. Thus the compensating ability is improved between a reactive current and a higher order harmonics.

Title: Amplifier circuit
Inventor: SUZUKI TAKEFUMI
IPC: H03F3/20
Filed: 1995-06-30
Abstract: PURPOSE: To quicken the switch timing when the power voltage follows an amplification signal from a constant power supply by quickening the switch timing when a switching element is switched to a normal switching action from a compulsive ON state when the amplification signal is kept at high frequency. CONSTITUTION: When a high frequency amplification signal is outputted, the differential value of the amplification signal detected by differentiation circuit DC contained in a timing adjustment circuit 20 is increased. Then the base potential of a switching transistor TrQ201 rises and this Tr is turned on. At the same time, a switching TrQ202 is also turned on but the timing of the TrQ201 is earlier than that of the TrQ202. Therefore, the base potential of a TrQ181 serving as the non-inverted input of a 3rd comparator 18 is reduced. Thus the TrQ202 is turned on earlier than the TrQ201 and therefore the reducing speed of the base potential of the TrQ181 is higher than that of the amplification signal of low frequency. Then the timing when a MOS TrTR 153 is switched to a normal state from a compulsive ON state is quickened.  As a result, the power voltage +Vc needs a long period to follow the amplification signal and the consumption power loss is reduced. Thus the deterioration of efficiency can be prevented for an amplifier circuit.

Abstract: PURPOSE:To eliminate the gap of a rear at the time of welding and to certainly apply a center falling gradient to a bottom plate by embedding a welding back patch in the foundation of a tank as a substrate material and executing a bottom plate module piece while mounting said module piece to the back patch by welding. CONSTITUTION:A bottom plate is formed as an one-plate structure and a welding back patch 7 is embedded in the foundation 3 of a tank as substrate material and the bottom plate is set to a downward gradient as a whole while bottom plate module pieces 2a, 2b are mounted to the back patch 7 by welding. Since it is difficult to provide a leakage detection mechanism like a double bottom plate structure, one or a plurality of linear leakage detection grooves 9a, 9b are provided to the back patch 7 and, when a center falling gradient is applied to the bottom panel to connect the whole, a leakage detection pipe is connected to the leakage detection groove gathering part formed to the center of the bottom plate.

Filed: 1981-10-19
Abstract: PURPOSE:To eliminate variation in feedback loop gain when amplifiers are independent and coupled together in parallel, by providing a loss circuit loop to each amplifier in parallel, and breaking the loss circuit loop of one amplifier when the other amplifier is disconnected. CONSTITUTION:Amplification part 3 and 3' are connected to an input coupling circuit 2 and an output coupling circuit 6, and part of the output of an output circuit 7 is fed back to an input circuit 1 through a feedback circuit 5 to constitute a no-break amplifier.
