Title: Vibration suppressing method for driving system
Inventor: FUJIKAWA ATSUSHI
IPC: H02P29/00
Filed: 1994-06-08
Abstract: PURPOSE:To stabilize a system by estimating the torsional speed based on the output from a torque measuring means for a drive shaft and performing the speed control of a load based on the difference between the estimated torsional speed and the motor speed. CONSTITUTION:A shaft torque TQ outputted from a torque measuring means T1 passes through a filter 14 and is multiplied by the reciprocal (1/Kch) of the nominal value Kch of the spring constant 15 of a drive shaft. The product is then subjected to approximate differentiation 16 to obtain an estimated value NTE of torsional speed. An estimated value WLE of load speed WL is also obtained from the estimated value NTE of torsional speed and a motor speed WM. Furthermore, a proportional gain is added and the nominal value Kch of the spring constant 15 of drive shaft is set larger than the estimated value thus stabilizing the system.

IPC: F04C18/02
Filed: 1994-06-08
Abstract: PURPOSE:To reduce a motor power for initial drive by a method wherein a bypass valve released at least at an initial exhaust stage is arranged in an arbitrary spot on an end plate on the fixed scroll side positioned on a closed space wherein an intermediate compression chamber not communicated with both a suction port and a delivery port. CONSTITUTION:Gas sucked in an inlet 34 through a suction port is compressed in a closed space (g) through drive of a revolving scroll 20 and pushes aside a ball against the force of a spring and is discharged to the outside. When a pressure in the closed space (g) is reduced to a value lower than an external atmosphere pressure, a bypass valve is closed and transferred in a space (i). Meanwhile, gas in a space (q) inputted in an inlet 35 through a suction port is compressed and transferred, in order, to closed spaces (p), (o), (n), (m), (l), and (k) by the revolving scroll 20 and discharged in an external space through the bypass valve by means of a discharge hole (36) of the closed space (k). When a pressure in the closed space (k) is reduced to a value lower than an external pressure, the bypass valve is closed, remaining gas is transferred in the space (i) and discharged to the outside.

Title: Controller for reactive power
Inventor: YAMAMOTO YOSHIHIKO
IPC: G05F1/70
Filed: 1977-12-14
Abstract: PURPOSE: To permit stable starting-up without casuing disturbance in system by comparing the outputs from system voltage detector and the output voltage detector and by drawing a signal to control output voltage in voltage control circuit.  
     CONSTITUTION: The system voltage detector 30 receives a system voltage signal from PT 10 and then generates a signal proportional to the magnitude of the system voltage. And, the contact 31 intrelocking with the operation of the switch 20 is provided with the contact b and the contact 32 is also provided with the contact a. For this reason, when the power invertor 5 and the power rectifier 6 start in a predetermined sequence at the time of starting-up, the output signal of the voltage control circuit 16 responds in the direction of a point where the deviation between the output signal of the system voltage detector 30 and the output signal of the DC voltage detector 14 becomes zero and is controlled so as to equalize DC current and system current. Thus, the magnitude of the generated voltage of variable voltage source becomes equal to that of system voltage before switch is closed, so that smooth starting-up can be made without causing disturbance in system.

Abstract: PURPOSE:To obtain a miniaturized multiband filter having sharp characteristics by forming a band pass filter(BPF) for passing a band including the passing area of a required frequency band and plural band stop filters for attenuating an attenuation area. CONSTITUTION:An amplifier circuit 40 constituted of a Si bipolar transistor(TR) as an active circuit is connected to a dielectric coaxial resonator 28 and constituted so as to be a negative resistor in the operation area of a band-stop filter 18. The BPF 16 passes a signal in a band including a required frequency band. Plural band stop filters 18, 20, 22 are used for attenuating signals in unrequired frequency bands. Since the active circuit 40 connected to the resonator 28 acts as a negative resistor in this case, the Q value of the band-stop filter is increased. Thereby, the plural band stop filters 18, 20, 22 are used for sharply attenuating signals in unrequired frequency bands. Consequently, the miniaturized multi-band filter having sharp characteristics can be obtained.
