Title: Circuit and method for driving display device
Inventor: SHIGETA KAZUYUKI
IPC: G02F1/133
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a circuit which makes a surface flicker inconspicuous and is suitably made high in density by inverting the polarity each time a video signal of one screen is outputted, and making the frequency of the inversion larger than the frequency of one-screen display of the video signal. SOLUTION: The polarity of the video signal is inverted each time the video signal is outputted by one screen and the frequency of the inversion is made larger than the frequency of one-screen display of the video signal. For the purpose, a frame memory 3 is provided, a video signal 24 is read out with a frequency larger than the write frequency of a video signal 22 and inverted, and a signal 25 for liquid crystal driving is written to the display device 6. Namely, field inversion driving whose field frequencyfv , after the read from the memory 3, is made double as high as the field frequency fv1 of the input signal is performed. Consequently, the write frequency of a liquid crystal screen becomes 160Hz from 100Hz and the frequency of luminance variation on the screen becomes >=50Hz, so a surface flicker which is recognized is reduced.

Title: Waveguide resonator
Inventor: ISHIZAKI TOSHIO
IPC: H01P1/212
Filed: 1988-01-22
Abstract: PURPOSE:To suppress the resonance of an unnecessary resonance mode by arranging the orientative film of a ceramic superconductor so that it can get onto the internal wall surface of a cavity resonating part composed of a waveguide and, simultaneously, that a crystal axis direction, in which a superconducting current in the superconductor flows, can coincide with the wall surface current direction of the resonance mode. CONSTITUTION:The place and direction of the current to flow on a resonator conductor wall by an electromagnetic field excited through a coupling hole 2 are different for each resonance mode. An orientation film 1 of the ceramic superconductor of an anisotropy, in which the superconducting current flows only in a specific crystal axis direction, is formed on the other substrate and stuck onto a resonator wall surface 3. When the direction, in which the superconducting current flows, and the wall surface current direction of the resonance mode are made to coincide, a loss cannot be generated at all as to the resonance mode. As to the current of the unnecessary resonance mode, by causing the direction of the superconducting current and the walle surface current direction to be orthogonal, the resonance can be suppressed.

Title: Stripe structure of semiconductor laser element and its manufacture
Inventor: KURATA YUKIO
IPC: H01S5/00
Filed: 1979-02-07
Abstract: PURPOSE: To obtain a semiconductor laser device with less oscillation starting current value by forming a current constriction area in the neighborhood of the active layer.  
     CONSTITUTION: Carriers injected from the electrodes 7, 8 are constricted in a narrow area by the layer 13 that is a constriction layer due to its high resistance when the layer has a higher resistance and due to a reverse bias characteristic when the layer is of the p-type. The area of Zn-diffused layer 18 is of the p-type, the diffusion front flows between areas that are connected to the layer 15, the carriers are made high dense in the neighborhood of the layer 15 that is an active layer. Also, since the lateral spread effect by the diffusion of carriers is made less, the semiconductor laser element shows a minute spot oscillation by a stable lateral mode with less threshold current. In this way, a semiconductor laser device with less oscillation starting current value can be obtained.

Title: Peak hold circuit and reception circuit for infrared remote control device having the same
Inventor: OKUDA TAKANORI
IPC: H04B10/69
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To eliminate influence of peaking in terms of a peak hold circuit to which a waveform of a reception circuit such as an infrared remote control device having the peaking is inputted. SOLUTION: A charging transistor Q10 that supplies a charging current to a hold capacitor C1 when an input signal Vin is higher than a terminal voltage Vc of the hold capacitor C1 is diode-connected to the hold capacitor C1. As a result, the current-amplifying is not executed by the charging transistor Q10 and the charging time constant can be increased to a time period, e.g. roughly 1msec, when peaking is generated. As a result, it is possible to reproduce an original waveform with complete fidelity by eliminating influence of the peaking in a discriminating level for waveform shaping formed based on a hold value.

Filed: 1993-02-01
Abstract: PURPOSE: To improve pump performance capable of increasing a pressure in an oil pressure tank of an aircraft to a maximum value with low-pressure air by using a mechanical AND gate to synchronize two oppositely reciprocating piston units. CONSTITUTION: Pistons 12, 17 move outwardly from each other in response to an oil pressure in a chamber 52, accordingly any one of ports 45, 46 in association with piston shafts 20, 15 of AND gate means reaches a point closed by the shaft. However, increase of a pressure in this port is prevented by the other port connected to an oil pressure returning outlet 67. When both the ports 45 and 46 are closed, the oil pressure increases at an end D1 of a spool 32 from a passage 44. When this pressure increase reaches a point overcoming a magnetic force between a magnetic end stop member 34 and an end P1, the spool 32 is forcedly moved rightward, and the other end P2 is held by the magnetic stop member 34.
