Title: Multi-projection video display device
Inventor: YAMAZAKI MASAMI
IPC: G03B21/00
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To synthesize video so as not to damage a seamless one-body feeling of whole video even through the whole video is displayed dark or with low brightness, by performing edge-blending processing combining two kinds of means of a video signal modulating means and a projection boundary brightness gradually attenuating means. SOLUTION: An input video signal 0701 is supplied to a projector via a video signal modulating means capable of arbitrarily modulating form, brightness, and color. The projector controls an imaging device so that an imaging device drive circuit 0702 reproduces the video of the input video signal 0701 as a space distribution of a transmittance on a liquid crystal transmitting imaging device 0703. The liquid crystal transmitting imaging device 0703 is irradiated from behind with the light of a light source lamp 0704, and a video is reproduced as brightness distribution on the imaging device. The video light on the imaging device is condensed by a projection lens 0705 through a projection boundary brightness gradually attenuating filter 0706 and focused on a screen.

Title: Drive device for ac elevator
Inventor: NOMURA MASAMI
IPC: H02H9/02
Filed: 1982-03-16
Abstract: PURPOSE:To suppress the rise of a rush current from a smoothing condenser when an inverter is defective by inserting a reactor connected in series with the condenser between the DC terminal of the inverter and the condenser. CONSTITUTION:A reactor 18 is inserted in series with a smoothing condenser 3 between the DC terminal of an inverter 4 and the condenser 3. Since the DC side current flows merely in ripple components without the reactor 18, the capacity of the reactor 18 may be small. When the inverter 4 is detective, the rise of the rush current of the condenser 3 is suppressed by the reactor 18. Further, the rise of the rush current from the condenser 3 when the inverter 16 for regenerating the current is suppressed by this reactor 18.

Title: Current controlling circuit for dummy load
Inventor: SHIGEMORI TAKEO
IPC: H02M3/28
Filed: 1979-04-09
Abstract: PURPOSE:To eliminate useless power consumption and increase the efficiency by a method wherein current flowing in a dummy load of a pulse-width control type switching regulator is subject to cut off when the load current exceeds a specified level. CONSTITUTION:In place of a fixed dummy load R2 inserted in the output end of a pulse-width control type switching regulator, a semiconductor load 10 as variable dummy load is connected. The difference between the second reference voltage Er2 and an output voltage of a voltage amplifier circuit 9, which is incoming from a current detecting resistor R1 and is to be supplied to an over-current detector 12, is amplified via an error voltage amplifier 11. The amplified error voltage controls the variable dummy semiconductor load 10. Thus the dummy load consumes the power until the load current exceeds a specified level. Once it exceeds the level, the dummy load is separated from the circuit so that useless power consumption is eliminated and efficient operation is ensured.
