Patent JP-H02214486-A (JP)
Title: Controller for elevator
Inventor: MIYANISHI YOSHIO
IPC: H02P21/34
Filed: 1989-02-13
Abstract: PURPOSE:To accelerate the rise of a magnetic flux and to output a correct torque by determining a conversion coefficient of an exciting current command calculated by an exciting current command calculator or a torque current command in response to the exciting component of a three-phase primary current transformed by a coordinates transformation circuit. CONSTITUTION:When a start command is output, a d-axis current command Id* rises simultaneously upon a start command. On the other hand, the output signal 15a of a speed control calculator 15 is zero up to a time point Ta when a speed command 13a for starting is generated even if a start command is input, and thereafter raised in response to a deviation from a speed detection signal 5a. The output signal 16a of an unbalanced load compensator 16 stepwisely rises to the compensating value of the unbalanced load together with the start command. A signal 17a of the addition result of the output signals 15a and 16a is multiplied by a target value of transformation coefficients 32, further divided by Id* to obtain a torque current command Iq*, thereby generating torque tau proportional to the Id*.

Title: Programmable switched capacitor filter
Inventor: NAKAYAMA KENJI
IPC: H03H19/00
Filed: 1983-03-01
Abstract: PURPOSE:To attain the compression of dynamic range of capacitance, reduction in the element sensitivity and unit capacitance value and also the area of capacitor and power consumption by using a switch so as to realize a filter and an equalizer having frequency selectivity. CONSTITUTION:Switches 18 are all turned on in realizing an LC ladder simulation type switched capacitor filter. In realizing cascade connection of secondary circuits, the switches 28 are all turned off. The switches 18 are mounted on a semiconductor substrate and the switching of them is controlled externally. The capacitance value of the capacitors in the secondary circuits is set by external control. Since an LPF, a BPF and an HPF are realized in a signal flow graph when the switches 18 are turned on, the constitution where the switches 18 are turned on is used when the filters are realized. On the other hand, the equalizer of an optional form is realized by turning off the switches 18, that is, opening a feedback loop, and using the entire circuit as the secondary circuits in cascade connection, when this system is used as the equalizer.

Title: Low-pressure discharge lamp device
Inventor: MATSUNO HIROMITSU
IPC: H01J61/56
Filed: 1987-02-18
Abstract: PURPOSE:To obtain a high-efficiency, low-pressure discharge lamp device which is small-sized and lightweight by combining a low-pressure discharge lamp limiting the distance between end sections of one electrode and a capacitor as a ballast. CONSTITUTION:The distance between end sections 1, 2 is limited so that one end section 2 of one electrode exists in a negative glow 3 when the other end section 1 acts as a cathode. Thereby, there is no anode voltage drop, and the arc re-striking voltage and the discharge voltage are reduced. Even if a capacitor 23 is used as a ballast in such a low-pressure discharge lamp, a sine wave current flows, no flicker of light occurs, and the loss by the capacitor is reduced. Accordingly, a high-efficiency, low-pressure discharge lamp device which is small-sized and lightweight can be obtained.

Title: Electromagnetic flowmeter
Inventor: SUZUKI ICHIU
IPC: G01F1/60
Filed: 1980-03-17
Abstract: PURPOSE:To make the circuit for an electromagnetic flowmeter simpler, cheaper as well as highly reliable by inserting a short circuit preventing circuit between the driving circuit for the switching transistors which alternately operate to reverse the direction of the current to flow through an exciting coil and the driving signal source. CONSTITUTION:When a positive driving signal is applied by a driving signal circuit 23, being delayed according to the time constant (t) of a short circuit preventing circuit 37 comprising a resistor 47 and a capacitor 48, an NPN type transistor (Tr) 18 conducts, and consequently, a switching transistor is turned on, so that a positive exciting current is allowed to flow through an exciting coil 13 from a power source 11. On the other hand, a PNP type transistor 21 is brought to a non- conducting state, and consequently, a switching transistor 16 is turned off with the  falling characteristics shorter than tau. When the driving signal is negative, similarly,  Tr16 is turned on, while Tr12 is turned off with the falling characteristics shorter  than tau, so that a negative current from the power source 15 flows through the exciting coil 13. Tr 12 and Tr16 never be turned on at the same time. Thereby, the circuit can be made simpler, cheaper as well as highly reliable.

Title: Electric spark machining
Inventor: SATOU KUNIHIKO
IPC: B23H1/02
Filed: 1978-03-24
Abstract: PURPOSE:To produce uniform aventurine surface by controlling frequency of inter- pole detection according to the rotation speed of the roll. CONSTITUTION:A low voltage pulse and a high voltage pulse are impressed in the machining space between an electrode 2 and a roll 1. A high voltage pulse and a low voltage pulse exist in mixture between the poles due to the same signals of an oscillating circuit 12, but the machining current is detected at a detector circuit 13 at time of low voltag pulse impression, whose detecting signal is distinguished at a distinguishing circuit 14 to determine the electrode feeding amount, and the electrode feeding device is operated by the driving dircuit 15. Thus, as the length of the inter-pole space is most appropriate at time of low voltage pulse impression, it is narrow enough for high voltage pulse discharge, letting most of the impressed high voltage pulse be discharged. In this way, even at time of vibration or highest rotation rate of the roll, the change of the machining space causes no machining amount, eliminating the generation of stripe patterns on the machined surface.
