Title: Vertical type thin film transistor
Inventor: SHINPO MASAFUMI
IPC: H01L29/78
Filed: 1984-01-26
Abstract: PURPOSE:To improve the light shielding property of the vertical type FET by a method wherein an opaque material of high specific resistance is inserted to a part of an insulation film. CONSTITUTION:A high-resistant thin film 16 having light shielding property is inserted at least to a part of the insulation film 6. Elements such as a-Si, a-Ge, Ge, and Sn-doped a-Si are used as the opaque, high-resistant material. The opaque, high-resistant film 16 is put under the insulation film 6 between the first and second main electrode regions 1 and 2, or the film 16 is put on the insulation film 6, resulting in the shielding of incident lights from below or above. Otherwise, incident lights above and below can be shielded by application of both methods. The channel length of a TFT is proportional to the film thicknesses of the insulation film 6 and the opaque, high-resistant film 16; the film thickness of the film 16 is determined by the channel thickness and light shielding property, and selected normally to approx. 0.2-2mum; therefore, the sufficient shortening in channel length is made possible.

Title: Storage system negative feedback power unit
Inventor: KITAMURA FUMIO
IPC: G01R33/12
Filed: 1988-01-25
Abstract: PURPOSE:To ensure an accurate and stabilized test even with the high magnetic flux density and with no control of the input voltage by storing the waveform equivalent to one cycle of a basic waveform and to undergo the negative feedback. CONSTITUTION:The waveform equivalent to one cycle of a basic sine wave and to undergo the negative feedback is stored and the negative feedback is applied with the one-cycle delay so that the high-frequency repetition of the negative feedback is avoided. In other words, only the component of the waveform error (voltage error) is taken out as a waveform that should undergo the negative feedback and stored (A). Then this waveform is corrected (B) after the negative feedback with the one-cycle shift secured. As a result, the negative feedback is separated from the positive feedback for each cycle of the basic sine wave even though the phase has an error of >=180 deg. in a high frequency area. Thus the growth and the oscillation are never produced by repetition of the positive feedback.

Inventor: KITAJIMA YASUO
IPC: H01H13/12
Filed: 1995-01-31
Abstract: PURPOSE: To provide a switch structure that makes effective use of movement space. CONSTITUTION: In the switch structure of a timepiece, the spring portion 1a of a switch is placed in a plane on a movement, a portion near the end 1c of the switch portion is placed on the lower surface of a circuit support plate 1 constituting the switch spring 1a, and the circuit support plate 1 having the switch spring 1a is fastened to the movement 2 by a plurality of hooks 1e.

Filed: 1987-01-22
Abstract: PURPOSE:To enable the precise control of a rotational torque by making a constitution in which a cone regulates the maximum opening of a circle core pendulum by means of its inner wall and a movement mechanism moves the cone along a motor rotational shaft and its own rotational shaft is driven by a motor. CONSTITUTION:The rotation of a motor 3 is transmitted to a rotational shaft 9, and also when a motor rotational shaft 3c rotates, centrifugal force determined by its rotational number is generated at a circle core pendulum 5, and the circle core pendulum 5 is opened to an angle well balanced with the force of a spring 5c. When the load of the rotational shaft 9 varies and its rotation number changes, a motor control circuit 4 conducts the control of a field electric current so that the rotational number of the motor 3 may be kept fixed. Also, the circle core pendulum 5 works as a governor which keeps the rotational number of the motor rotational shaft 3c fixed. Also, when the circle core pendulum 5 opens and its tip comes into contact with the inner wall of a cone 6, its opening stops, and the cone 6 and the circle core pendulum 5 are together started to rotate by a cone movement mechanism 7, so the maximum opening of the circle core pendulum 5 can be voluntarily regulated by the regulation of the movement mechanism 7.
