Title: Semiconductor device
Inventor: TAKAHASHI JUNICHI
IPC: H01L29/78
Filed: 1985-11-15
Abstract: PURPOSE:To reduce the area of a device by forming a gate oxide film and a gate electrode in the vertical direction to a substrate from a base layer to a source layer, and by forming a channel in the base layer in the vertical direction to the substrate. CONSTITUTION:An N-type epitaxial layer 2 is formed on a semiconductor substrate 1, a P-type base layer 3 on the surface of the layer 2, and an N-type source layer 4 in a plane region in a part of the base layer 3. A gate oxide film 6 is formed on the lateral side of a groove 5 which extends vertically from the source layer 4 down to the base layer 3 and a part of the epitaxial layer 2, and a gate electrode 7 is formed inside the groove 5. When a positive voltage is impressed on the gate electrode 7, an N-type channel 10 is formed in the P-type base layer 3 in the direction vertical to the semiconductor substrate 1, and a current flows through a source electrode 9, the source layer 4, the channel 10 and the epitaxial layer 2 and to the semiconductor substrate 1 in the vertical direction to the semiconductor substrate 1. Even when the dimensions l0 of the plane of the gate electrode 7 are reduced, the current is not concentrated on a part, and thus the area of a device is reduced, while MOSFET having little ON resistance is obtained.

Title: Driver circuit
Inventor: YOKOI KATSUYUKI
IPC: G06K15/00
Filed: 1987-10-08
Abstract: PURPOSE:To detect a change in load energy for a constant supply of energy by providing a simple circuit in which the output voltage from a non-regulated source is detected by a voltage detector whose output voltage and current control the supply of current to a load.

IPC: G02B7/34
Filed: 1986-10-27
Abstract: PURPOSE:To move a lens to an objective position at a time by detecting the extension of pulse generating intervals based on the rotating operation of a motor at the time of starting the motor and restarting the counting of generated pulses. CONSTITUTION:An automatic focusing device is provided with a means 6 for detecting the extension of pulse generating intervals based on the rotating operation of the motor at the time of starting the motor and a reset means for restarting the counting of generated pulses from the detecting point of time. When backlash exists at the time of starting motor driving, encoder pulses based on the rotation of the motor are generated at comparatively short intervals and the interval is gradually shortened in accordance with the acceleration of the motor. When the lens starts to move after the generation of pulses corresponding to the backlash, torque is suddenly increased and the interval of the encoder pulses is suddenly extended. Since the encoder pulses include the backlash up to a point of time suddenly extending the torque, the objective number of counts is reset at the time of ending the backlash to execute accurate lens driving including no backlash.

Abstract: PROBLEM TO BE SOLVED: To make it possible to enhance a favorable snow melting performance by using a radiator which is excellent in far infrared radiation efficiency and high heat holding and emitting actions. SOLUTION: According to this base structure, a resin-made waterproofing sheet 10 is laid out on a subgrade and an insulating material 11 is laid out on the water-proofing sheet 10. A metal-made net-shaped member 12 is laid out in the upper part separated from the waterproofing sheet 11. A heating body 13 into which a heating fluid is arranged to flow, is fixed with the net- shaped member 12 and a base material 14 is provided on the upper and lower part of the net-shaped member 12, which is concrete mixed with a radiator substance S adapted to flow thereinto and be cured. The radiator substance S is constituted with a crisbalite ceramic body Sa, which employs crisbalite as a quarry and forms and incinerates a crisbalite powder obtained from crushed quarry.  Since the crisbalite is excellent in far infrared rays radiation efficiency and provides an exceptionally large specific surface compared with the other ceramics, its heat holding and emitting action is high. It is, therefore, possible to promote snow melting by heat radiation thus accumulated in addition to the action by far infrared ray radiation.

Title: Control method for inverter
Inventor: MOCHIKAWA HIROSHI
IPC: H02M7/48
Filed: 1991-10-03
Abstract: PURPOSE:To reduce noise by decreasing a PWM modulation frequency by a quadratic function of an output voltage command value of an inverter according to a special equation if the command value is 1/2 or less of a highest voltage. CONSTITUTION:A voltage command value generator 1 generates a voltage command value V corresponding to a frequency command value F. The value V is given approximately in proportion to the value F. However, since it cannot output a highest voltage or more controllable by a sine wave PWM in a high frequency range, the value V coincides with the highest voltage, exhibiting saturated characteristics. A modulation frequency subtracter 2 generates a modulation wave number command value F'c corresponding to the value V. Here, if it generates an output voltage waveform without synchronization with the PWM modulation wave and the value V is 1/2 or less of the highest voltage controllable by the PWM, the modulation frequency Fc of the PWM is reduced by the output voltage command value of an inverter according to the equation (K1, K2: positive constants), the quadratic function of the V. Thus, noise can be reduced.
