Title: Controller for inverter
Inventor: KISHIMOTO TAKESHI
IPC: H02P25/04
Filed: 1984-08-16
Abstract: PURPOSE:To stably control an inverter and its load by setting to contain a current zero cross point in the noncommutation period of the inverter to eliminate the immediate influence even if a variation occurs in a load. CONSTITUTION:An inverter has a setter 30 for generating a voltage Vphi corresponding to a phase phi, a converter 31 for generating a signal Fphi of the same frequency as the frequency signal Fr by the voltage Vphi, and an analog-to-digital (A/D) converter 31 for supplying addresses C1-CM digitally converted from the signal Fphi in memory units 4-6. If the phase phi is 0, the zero cross point of a current IU is not, as shown in the waveform diagram (a), contained in the noncommutation period TNCV of a voltage VUN. In case of the phase phi>0, the zero cross point of the current IU is contained, as shown in the waveform diagram (b) in the noncommutation period TNCV of the voltage VUN. In this case, even if the variation in the charge storage time of a transistor or the variation in the frequency of a voltage VUN occurs, a transient variation is absorbed in the noncommutation period to hold the stability of a control system.

Abstract: PROBLEM TO BE SOLVED: To provide a vibration suppression effect in a wide running speed range and to improve comfortableness by a method wherein a frequency at which a vibration component exerted on a car body is maximized is found from a running speed and a frequency range to be controlled is changed by that frequency. SOLUTION: A running speed is found by a running speed detecting means 23 and a frequency at which a vibration component applied on a car body is maximized is determined and a control rule varying means 20 is inputted. The control rule varying means 20 determines the time constant of the high pass filter of a compensator 21 for controlling yawing and rolling and varies the characteristics of vibration compensators 21y and 21r. Further, the laterial vibration acceleration of the front and the rear parts of a car body is detected by acceleration meters 22f and 22b. From detecting results therefrom, the vibration control compensators 21y and 21r separate vibration acceleration into yawing and rolling components and independently compute a control signal.  A control signal synthesizer 21p weights and adds and inputs a result as a control signal, by which a hydraulic working mechanism 31 is operated, to a servo valve 32.

Filed: 1985-08-02
Abstract: PURPOSE:To enable miniaturization and to prevent the deterioration of a photosensitive body in terms of an electrophotographic device for an information storing device by forming an air exchanging fan on flanges installed at both end sides of a photosensitive drum. CONSTITUTION:The flanges 2 giving rigidity to the photosensitive drum are installed at both sides of the photosensitive drum 1. The fan exchanging air is formed on the flange 2 in the vicinity of the drum 1. The flanges 2 with the fan, fixedly installed at both sides of the drum 1, are rorated due to the rotation of a rotating spindle not shown in the figure, and act as a rotating wing. In accordance with the fan's shape and the rotating direction, an air flow is generated in the direction of an arrow 4 and in parallel with a drum spindle core 5, or its reverse direction, as the figure shows. Due to the rotation of the drum 1, the interior of the drum 1 becomes a negative pressure without fail, and accordingly leads in ozone generated in the vicinity of the drum 1 and suppresses the temperature hike with the aid of the air flow 4. Thus the device can be scaled down, and simultaneously the deterioration of the photosensitive body can be prevented.
