Title: Method for controlling visibility of display screen and device therefor
Inventor: KNIGHT KENNETH ROBERT
IPC: G09G3/18
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a technique capable of easily adjusting the visual angle of a display screen of an LCD(liquid crystal display device) panel. SOLUTION: The display device includes the display screen 21 for displaying information. The LCD panel 70 is adjacent to the display screen 21. The LCD panel 70 is controlled so that the selectable parts of the display screen 21 selectively regulate the visual angle at which the viewing through the LCD panel 70 is possible. The LCD panel 70 includes plural energizable segments 80 which are opaque when energized. The plural energizable segments 80 are respectively selectively energizable to selectively regulate the visual angle at which the viewing of the information on the display screen 21 through the LCD panel 70 is possible. The segments of the LCD panel 70 are parted from each other across the LCD panel 70 in order to provide the privacy screen of a louver type when the segments 80 are opaque.

Title: Lsi tester
Inventor: HAYASHI EIJI
IPC: H01L21/66
Filed: 1995-04-14
Abstract: PURPOSE: To obtain an LSI tester which reduces a leakage current and whose response is made quick by a method wherein, when a current is injected through a current injection line, one pair of switches across an output amplifier and an element to be injected are closed, another switch across a switch connection point and a grounding resistance is opened and all the switches are operated reversely when the injection line is not used. CONSTITUTION: The output voltage Vo of an output amplifier 10 is sent to an element 20, to be inspected, by a current injection line HF, and switches SW1 , SW2 are inserted in series across both. The connection point P of the switches SW1 , SW2 is connected to a grounding resistance Rs via a switch SW3 . When a current is injected into the element 20 through the injection line HF from the amplifier 10, the switches SW1 , SW2 are closed, and the switch SW3 is opened. In addition, when no current is injected into the element 20, all the switches are operated reversely.  In addition, since a potential on the side of the element 20 of the switch SW2 is made equal to a potential on the side of the switch SW1 by a compensating amplifier 49, it is possible to obtain an LSI tester in which a leakage current is reduced and which is operated at a high switching speed according to the switching frequency of an amplifier 40.

Title: Fm demodulation circuit
Inventor: HIKITA JUNICHI
IPC: H03D3/06
Filed: 1986-04-17
Abstract: PURPOSE:To eliminate inconvenience of an IF-AMP side due to DC offset by using a bridge circuit employing the impedance relation of a solidstate resonator and a resistor and the impedance relation by capacitance division for a phase shifter. CONSTITUTION:A phase shifter 20 deviating an FM signal 10 by a specific phase angle provided, an FM signal subjected to phase deviation obtained from the phase shifter 20 and an FM signal not subjected to phase deviation are muliplied to demodulate the FM signal. In the FM demodulation circuit as above, the bridge circuit employing the impedance relation of the solidstate resonator 12 and the resonator 14 and the impedance relation by the division of capacitors 72, 74 is used for the phase shifter 20. Since the phase shifter is constituted by using the capacitors in this way, the DC offset caused at an intermediate frequency amplifier side is cut off by the capacitors in the phase shifter to eliminate the effect onto the multiplication processing side without increasing special parts and terminals. The deterioration of ripple rejection due to DC offset is completely avoided.

The DC 2  counts the output pulses tg of a speed generator, its output becomes to "L" when value reaches n, the Tr3 is in ON because the output c of the NOR becomes to "H" and the TGR 2  is set. Reliability can be improved because abnormality is detected by such functioning.

Abstract: PURPOSE:To remove noise components automatically and to make it possible to detect pressure highly accurately by applying a first pressure on one surface of each of two piezoelectric elements, applying a second pressure on the other surfaces of the elements, and obtaining the sum of the outputs of both elements. CONSTITUTION:A fluid pressure P1 from one outlet port of the element part of a flowmeter is introduced into one surface of each of piezoelectric elements 2 and 3 through a nozzle 29 and an introducing path 33. A pressure P2 from another outlet port is introduced to the other surfaces of the elements 2 and 3 through a nozzle 30 and an introducing path 36.

Noise components due to pressure fluctuation and temperature fluctuation which are generated in the entire fluid are removed with the elements themselves. When the sum of the outputs is obtained, the sensitivity twice between than before is obtained. Thus, the highly accurate pressure detection can be performed.
