Title: Controller for linear motor electric railcar
Inventor: ITO KEN
IPC: B60L9/18
Filed: 1988-04-22
Abstract: PURPOSE:To supplement a decrease in a thrust due to end effect and to maintain predetermined thrust characteristic by increasing the output voltage of an inverter in response to the increase in an inverter frequency when it is located in a PWM range. CONSTITUTION:An adder/subtractor 10 adds or subtract an acceleration signal v from a pulse generator 8 and or from a slip frequency signal fs from a slip frequency controller 11, and outputs an inverter frequency signal finv. A voltage controller 13 outputs an inverter output voltage signal vinv responsive to the signal finv. A PWM modulator 7 outputs a PWM control signal to an inverter 2 in response to an inverter frequency signal and an inverter output voltage signal. Here, the inverter output voltage is increased in response to an increase in the inverter frequency and the slip frequency is also increased in response to the increase in the inverter frequency in a PWM range (variable voltage range).

Title: Bicolor printing method
Inventor: TASHIRO TSUNEO
IPC: G03G15/01
Filed: 1980-07-18
Abstract: PURPOSE:To achieve bicolor printing easily by forming a high-potential and a low- potential electrostatic latent image by performing scanning exposure while changing the illuminance of scanning light by two stages after electrifying the surface of an electrophotographic photoreceptor to a uniform potential. CONSTITUTION:A photoreceptor 2 is a p type semiconductor and on its surface, positive electricity having a surface potential V1 is generated. Then, scanning exposure is carried out in the axial direction of the photoreceptor 2 by laser light and when the laser light is scanning at a place equivalent to white paper, the output of a modulator 5 is at a low level, thereby adjusting the surface potential of the photoreceptor 2 to a V2 nearly a half the V1. When the laser light is scanning at a place equivalent to a black character 23, on the other hand, the output of the modulator 5 is a ''0'' and the surface potential of the photoreceptor 2 is still the V1; when it is scanning on a red character 24, the surface potential is the ''0''. Thus, electrostatic latent images of the black character part and red character parts whose surface potentials are the V2 and 0 are formed easily on the photoreceptor 2.

Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of determination by measuring the rotating speed of an engine and accessories interlocking with each other through a belt to calculate the rotational ratio, and calculating the fluctuation value of the rotational ratio according to the rotational ratios of plural times to determine the lowering of belt tension when the fluctuation value exceeds a designated threshold. SOLUTION: A belt 5 is wrapped round a crank pulley 2, an alternator pulley 3 and a compressor 4 of an engine main body 1, and they are rotated together with the rotation of the crank pulley 2. In this case, the rotating speed of the crank is measured according to a rotation signal for controlling an engine, and the rotating speed of the alternator is measured by a P terminal of the IC regulator. According to the measured rotating speeds, the rotational ratios are calculated by an arithmetic unit, and the fluctuation value of the rotational ratio is calculated by an abnormality determining device. As a result, when the fluctuation value is larger than the threshold as an index for lowering of belt tension, it is determined that the belt tension is lowered to give a warning.

IPC: B65H27/00
Filed: 1988-04-23
Abstract: PURPOSE:To reduce weight and cost, and to dispense with the need of machining of a roller shaft by providing the roller shaft made of plastic to the roller body made of urethane foam elastomer. CONSTITUTION:A roller body 1 is made of urethane foam elastomer. In the central part of the roller body 1, a roller shaft 2 is inserted, and it is so contrived that the roller body 1 and the roller shaft 2 are not subject to relative rotation. And, the roller shaft 2 comprises a shaft body 2a and end members 2b which are joined to both ends of the shaft body by means of heat, welding, or the like. The shaft body 2a is constituted by cutting a plastic-made pipe to a prescribed length, and it is inserted into the central part of the roller body 1 so as to penetrate nearly the entire length. Since the roller body 1 is made of urethane foam elastomer, the frictional coefficient of the roller body 1 can be increased, and the pressing force can be reduced. Thus, even if the roller shaft is made up of plastic, the roller shaft can be enabled not to be deflected.

Title: Automatic power factor controlling system
Inventor: TAKANO MUTSUMI
IPC: G05F1/70
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce the frequencies of making and tripping of a capacitor, and moreover to achieve linear control of a power factor. SOLUTION: Leading-phase capacitors SC1 to SCn and an active filter AF are connected to the secondary side bus B of a incoming and transforming facility. An automatic controlling device is provided which selects and makes the SC1 to SCn in such a way that correcting power factor required to attain preset power factor falls within the capacity of a single capacitor. While this device controls the making of the SC1 to SCn, the reactive power within the capacity of the single capacitor left intact in this control of making is corrected by a reactive power correcting function of the active filter AF. Because the selection and making of the capacitor with the automatic controlling device is performed so that power factor becomes within the capacity of a single capacitor with which it does not reach a preset power factor, the makings and trippings occur less frequency. Also, the amount of the corrected power factor always existing within the capacity of a single capacitor is corrected by the AF, so that linear control becomes possible.
