Title: Operating method for reactive power compensator
Inventor: YAMAZAKI HIROKAZU
IPC: G05F1/70
Filed: 1986-09-09
Abstract: PURPOSE:To suppress the excessive energization of each thyristor element with no increase of the cost and to ensure the continuous operation of a reactive power compensator, by providing a detector to detect a defective one on many parallel energizing circuits and having the control value equivalent to the capacities of other nondefective energizing circuits for operation of said compensator. CONSTITUTION:The troubles of parallel circuits 14 can be easily detected by the breaks of fuses 15. If one of five parallel circuits 14, for example, has a trouble, 75% of a reactor current IRE is used as a full current against 100% of a reactive current IQL of a fluctuating load. A block zone 50 is extended to beta+A from beta in terms of the ignition of a thyristor element. As a result, the energizing current of a reactor 12 is reduced down to 75% at maximum. Thus the control value is secured in response to the capacities of other remaining thyristor elements and a reactive power compensator is continuously operated with said reduced capacity.

Title: Fusion splicing method and fusion splicing device for optical fibers
Inventor: SUZUKI ISAO
IPC: C03B37/10
Filed: 1993-08-05
Abstract: PURPOSE:To obtain a specified electric discharge power by adequately correcting the fluctuating-component of the atm. pressure even if the number of coated fibers to be simultaneously fused changes. CONSTITUTION:For example, an atm. pressure sensor is used as an atm. pressure detecting section 24 and its output signal is taken as atm. pressure data into an arithmetic processing section 34 (CPU). Correction information meeting the number of the coated fibers to be simultaneously connected is previously inputted into the CPU. The adequate correction rate is determined by sending the signal meeting the number of the coated fibers to be simultaneously connected into the arithmetic processing section from an input setting section 30. The coated fibers are, therefore, simultaneously connected with low loss even if the atm. pressure and the number of the coated fibers fluctuate.

Title: Start control method of vehicle
Inventor: ITOU HIROSHI
IPC: B60W10/11
Filed: 1982-12-06
Abstract: PURPOSE:To enable a smooth start automatically by terminating increasing the engagement load when the rotational speed of a drive member of a friction clutch is under a predetermined value, and by resuming increasing the load when the rotational speed of the drive and driven sides is equal. CONSTITUTION:When the gas pedal is stepped on with the drive range selected and the throttle opening by a sensor 141 reaches to a predetermined value, a control device 140 outputs a pulse of a predetermined duty ratio to a solenoid valve 111 to reduce the oil pressure in an oil chamber 96 of a clutch release cylinder device 95, while when the engine speed Ne by a sensor 144 is increased to a predetermined value, the duty ratio is gradually reduced to proportionately increase the engagement load. When the rotational speed Ne becomes lower than a predetermined value, increasing the load is terminated, and when therotational speed Ne becomes equal to that of the driven side member of a frictional clutch as calculated based on the vehicle speed by a sensor 142, the solenoid switch valve 111 is turned off to complete the clutch engagement. Thus, a smooth automatic start can be done without a shock.

IPC: G11C11/34
Filed: 1986-09-12
Abstract: PURPOSE:To allow two processors have an arbitration circuit to prevent the occurrence of the competition of a port request signal by accepting the port request signals for an inner circuit, which are made optionally accessible from two processors respectively, through the use of a time sharing system by a periodic timing signal. CONSTITUTION:At the arbitration circuit ABT, according to the high level/low level of the periodic timing signal phi, under the condition that each other of microprocessors MPUb or MPUa does not use the port, the acceptance of the port request signals, the inverse of RQa/the inverse of RQb is performed through the time sharing system. Consequently, for instance, though, in the period of the high level of the timing signal phi, both the port request signals, the inverse of RQa and RQb are simultaneously made to be active at the low level, the acceptance of the signal, the inverse of RQa is permitted. Thus, according to the periodic timing signal, the port request signal of only one side is always accepted, therefore the competition of two port request signals can be avoided and the throughput of the system can be improved.

IPC: B60T13/12
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To secure superior brake feeling by reducing impact noise generated by the retreat of a piston in releasing a brake operation member. SOLUTION: A liquid chamber (a power chamber R1) is formed in the rear part of a piston (a second piston 12) and a communicating passage it for communicating to the liquid chamber is formed. The passage area of the communicating passage to the liquid chamber is so formed that it is set to a micro area forming a restriction, at least, in the initial moving region from the rear end position of the piston and increased according to the forwarding movement of the piston in the region after exceeding the initial moving region. The outer circumferential surface of the piston rear part is set to a tapered shape as a means for forming the restriction. The brake operation is thus released so as to retreat the piston and, when the piston is brought in contact with a cylinder body, the liquid chamber is functioned as a damper chamber so as to reduce the impact noise.

Title: Rewinder control device
Inventor: MIYAGAWA SOICHI
IPC: H02P29/00
Filed: 1988-08-29
Abstract: PURPOSE:To improve operation efficiency by increasing acceleration till a load current reaches the permissible maximum current and keeping the acceleration to a fixed value after the load current reaches the permissible maximum current. CONSTITUTION:When an electric motor is driven by an electric motor controller unit 17, a load detector 11 detects a load current and feeds it to an acceleration decision means 12. When, with an increase of the reference speed, the load current increases and reaches a permissible maximum current Imax, the acceleration decision means 12 feeds a signal for keeping acceleration to a fixed value to an acceleration generating part 14. Accordingly, the acceleration generating part 14 outputs a fixed acceleration signal, so that a reference speed signal is output from a reference speed arithmetic means 16, and the load current is maintained to the permissible maximum current Imax. When the reference signal increases and approximates a preset speed from a rewinding speed generator 18, a signal of speed reduction is fed to the acceleration generating part 14 from the speed reference arithmetic means 16, feeding an output so as to decrease the acceleration signal on the basis of this speed reduction signal, so that the reference signal is transferred to the preset speed, and a fluctuation of tension is suppressed of a sheet material.
