IPC: G09F9/33
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption on half tone display by constituting a MOS transistor(TR) as vertical structure for allowing a carrier to run in the film thickness direction of a semiconductor layer formed on a substrate. SOLUTION: Ferroelectric controlling electrodes and signal electrodes are formed like a matrix by a thin film semiconductor process and a MOS type switch element is formed on an intersecting part of respective wirings. The switch element has vertical thin film TR structure and allows a carrier to run in the film thickness direction of the semiconductor layer formed on the substrate. In this case, a silicon active layer 9 is deposited on signal electrodes 10 formed like strips and a ferroelectric film 7 is deposited on the layer 9. Ferroelectric controlling electrodes 8, 11, 13 are also patterned so as to intersect with the electrodes 10 while leaving the film 7 like a comb. Then connection holes to be connected to the lower silicon active layer 9 are formed on a display pixel electrodes and a silicon active layer 6 is deposited again so as to fill the holes.  Then a display electrode 5 is formed on the layer 6 in each pixel to obtain an array substrate.

Filed: 1983-06-15
Abstract: PURPOSE:To prevent a video signal at the standard speed from being affected with change in speed by changing the ratio of an effective horizontal scanning region period to a horizontal blanking period in a TV camera having a higher scanning speed and restoring the ratio to the initial value at the speed conversion. CONSTITUTION:The scanning speed of a television camera 21 is N times the standard scanning speed and the ratio of the effective horizontal scanning region period to the horizontal blanking period is set smaller than that of the standard scanning speed, i.e., the horizontal blanking period is set wider.

Then the output of the A/D converter 23 is fed to a speed converting circuit 24 and the time ratio of the effective horizontal scanning region period to the horizontal blanking period is restored to the normal ratio. No effect is exerted on the video signal in the standard speed in such a way.

Title: Low-inertia induction motor for vvvf control
Inventor: AKIYAMA YUUJI
IPC: H02K17/02
Filed: 1982-06-23
Abstract: PURPOSE:To reduce the loss based on a low-slippage characteristic and to obtain high efficiency by a method wherein the secondary conductor of a low-inertia induction motor is composed of copper. CONSTITUTION:The induction motor is composed of a rotary shaft 1 rotatably supported by a frame 14 of a stator, a cylindrical rotor core 3 having a given gap relative to the inner periphery of a stator core 11 rotatably supported on the shaft 1 and acting as a magnetic circuit on the secondary side, and a thin cylindrical secondary conductor 7 formed of copper and supported on the rotary shaft 1 at both axial end parts thereof. With this arrangement, since the magnetic circuit occupying most of inertia of the rotor, i.e., an idler rotor is freely rotatable on the shaft, it will not contribute to rotor inertia at the time of acceleration and deceleration. This results in the structure with lower inertia than that of the conventional squirrel-cage induction motor beyond comparison.
