Title: Picture display device
Inventor: NAGANO AKIHIKO
IPC: G09F9/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To align the direction of an object at the time of photographing by a camera with that of a subject image at the time of viewing by providing reflection surface inverting the direction of an image to an optical axis in a specified direction by reflecting write-in light in odd-numbered stages. SOLUTION: The subject image recorded on film 2 is reflected by a reflection mirror 42, and is made incident on a projection lens 3 by inverting in a film image width direction to the optical axis. Next, the subject image is inverted by the projection lens 3. Then, the subject image is reflected by the reflection mirror 41, and is inverted in the film image width direction to the optical axis, and also is reflected by the reflection mirror 4 and is inverted in the film image width direction to the optical axis, so that image-forming is executed at a spatial light modulation element(SLM) 1. Thus, the observer viewing the film image of the SLM 1 views the image in a right image direction because the subject image displayed by the SLM 1 and that of the object photographed by the camera are aligned.

Title: Solar power generator
Inventor: ISHIDA YUJI
IPC: H01L31/04
Filed: 1987-07-15
Abstract: PURPOSE:To obtain a solar power generator capable of improving overall gener ating efficiency, by using a superconductive power storage device instead of a battery. CONSTITUTION:In case the power can be obtained from a solar cell 1 having sufficient quantity of solar radiation and exceeding the load demand, the electro motive force corresponding to the reverse electromotive force of a superconducting coil 9 is given across the coil 9 in order to charge the superconductive coil 9 with dump power. At the same time, on the side where a VV converter 8 is connected to the solar cell 1, the function to follow the optimum operating voltage of the solar cell 1 is maintained. Conversely at night, the discharging voltage across the superconducting coil 9 is controlled, while necessary power can always be supplied from the VV converter 8 by constantly keeping the input voltage of an inverter device 2. On the other hand, the refrigerant required for the maintenance of the superconducting coil 9 is purified and liquified with a refrigerator 7 and supplied to the superconducting coil 9. The refrigerant which evaporated here is sent to the solar cell, then to the refrigerator 7, cooling the solar cell 1.

Title: Overvoltage suppression circuit for semiconductor switch element
Inventor: TOMITA HIROO
IPC: H03K17/695
Filed: 1988-07-13
Abstract: PURPOSE:To suppress an overvoltage by connecting a series circuit comprising a Zener diode and a capacitor between a drain and a gate of a FET. CONSTITUTION:A DC power supply 8 and a load 7 are connected in series between the drain and source of a switching MOSFET 1. A gate drive circuit 6 is connected between the gate and source of the FET 1 via a resistor 4. If a drain-gate voltage VDG exceeds a Zener voltage VZD of the Zener diode 2 when the FET 1 is turned off, a current flows to a series circuit comprising the diode 2 and a capacitor 3, the gate-source voltage VGS rises, the OFF operation of the FET is relaxed to suppress the overvoltage. The similar effect is obtained by connecting a series circuit comprising a Zener diode and a capacitor between the collector and base of a switching bipolar transistor.

Title: Image processor
Inventor: ONO KAZUSHI
IPC: G06T1/00
Filed: 1993-07-15
Abstract: PURPOSE:To take out a partial image out of a read image even when an original image and an additional image have the same color by comparing the read image signal with the stored reference image signal and transmitting the additional image signal of a prescribed image. CONSTITUTION:An image is added to a part of an original that outputted a reference image signal, and this additional image is read by an image reading means 1. A separating means 3 compares the read image signal with the reference image signal stored in a reference image signal storing means 2 to secure coincidence of positions between both image signals. These coincident reference and read image signals are compared with each other at every picture element. Then the white and the black are outputted in the coincident and non-coincident states respectively. Furthermore the decided noises and a decided non-coincident state caused by deterioration of the image resolution are eliminated based on the connection between the non-coincident picture elements and their peripheral picture elements. Thus the means 3 outputs only the parts different from each other between the reference and read image signals so that the additional image is stored in a separate image signal storing means 4.
