Title: Inverter controller
Inventor: SHIBUYA TADASHI
IPC: H02J3/18
Filed: 1994-09-12
Abstract: PURPOSE: To obtain an inverter being employed for reactive power compensation in which the inverter can produce an output current not affected by the ripple of DC voltage while reducing the size and cost. CONSTITUTION: The main circuit comprises an AC reactor, a DC capacitor, an inverter and circuits for detecting voltage and power. A synchronism control circuit 21 is synchronized with the power supply frequency and the output therefrom is employed as a reference. Difference between DC voltage of the inverter and a set value is amplified and added to the reference value by means of an adder 23. A frequency control circuit 24 controls the frequency of the inverter based on the output from the adder 23. Difference between the reactive power QL of a load and the reactive power Qi of the inverter is them amplified to produce an output voltage command value for the inverter.  An adder 27 adds a ripple component, produced from an output waveform correction circuit 25 by removing the DC component from a DC voltage, to the command value with reverse polarity thus correcting the waveform of output current.

Title: Cassette loading and ejecting device
Inventor: SHIMIZU HIROHIKO
IPC: G11B17/043
Filed: 1991-08-02
Abstract: PURPOSE:To solve the point at issue on such a matter that when the cassette loading and ejecting device for a floppy disk cassette, etc., is made to thin structive, an ejection button provided on a front panel and a cassette inserting hole are positioned close to each other, and hence a finger, etc., which pressed the ejection button are abutted against the disk cassette to be ejected, so that the cassette is hardly ejected. CONSTITUTION:The front end of a slide plate 1 is extended and formed integrally with a front panel part 1c. At the time of ejecting the disk cassette, an optional place of the front panel part 1c is pressed. By this method, the slide plate 1 is slid, and the cassette in a disk holder apart from a loading position is ejected from the cassette inserting hole 1d. Since an optional place of the front panel part 1c can be pressed, even when the front panel part is made to thin structive, a finger which pressed the ejection button is prevented from abutting, etc., against the disk cassette to be ejected.

Title: Magnetic recording write circuit
Inventor: MUKOYAMA FUMIAKI
IPC: G11B5/09
Filed: 1985-09-30
Abstract: PURPOSE:To improve the read margin by giving an optimum correction quantity during the period when unbalance correction of a write current is really required so as to reduce a peak position shift at write remarkably. CONSTITUTION:The effect of a magnetic field of an erase coil 2 and an external magnetic field is cancelled by increasing a current flowing to a read/write coil 1a more than the current flowing to a read/write coil 1b. Thus, the current flowing to the read/write coil 1 is increased via a diode 13 by a driver 7 and a correction current setting resistor 22 while an EG is turned on. However, even when a command signal WG is set, no correction is applied until an erase control signal EG is set. A signal RESET is a reset signal generated at power ON.

Title: Passage controller
Inventor: GOTO SEIICHI
IPC: E05B49/00
Filed: 1989-08-24
Abstract: PURPOSE:To prohibit the passage of a third party by detecting the rotational signal of the knob of a door, and judging the permission of the traffic based on information from a body weight meter and the information from a card. CONSTITUTION:A sensor 4 performs communication with a non-contact ID card 3 corresponding to the rotational signal of the knob 1b of the door 1, and a CPU 8c controls the unlocking of the lock 1a of the door 1 by performing collative judgement based on a read ID number and the detection of body weight with the body weight meter 2. Therefore, a traffic permission judging operation included in an ordinary door opening operation is also applied to a passerby. In such a way, a judging processing for passage permission can be performed between the non-contact ID card 3 by radio only by holding and turning the knob 1b even without performing a specific operation by the passerby in traffic control. Furthermore, since the body weight meter 2 is used as a means to specify a passerby principal, individual identification can be performed, which prevents the passage of the third party from occurring.

Filed: 1987-08-31
Abstract: PURPOSE:To reduce the relative deviation in the positions of a stopper and a leaf spring and the variation in the stopping position of a carrier by fitting the leaf spring via the stopper to a fitting part of the carrier. CONSTITUTION:The fitting part is provided on a comparatively rear part of the carrier for conveying a disk by way of moving back and forth against a housing 14, and the stopper 6 is fitted to this fitting part, while the leaf spring 11 is fitted to the stopper 6. Then, a protrusion part 15 is provided comparatively on a front part of the housing 14, where a switch 16 is arranged in this vicinity. Consequently, when the carrier is advanced from the housing 14, the stopper 6 is brought into contact with the protrusion part 15 so as to prevent the carrier from coming out. Then in this case, the switch 16 is pressed by the leaf spring 11, thus stopping the rotation of a motor for driving the carrier. By this method, the variation in the stopping position of the carrier is hence prevented.
