Title: Junction type field effect transistor
Inventor: TANAKA TADAHIKO
IPC: H01L29/808
Filed: 1980-06-05
Abstract: PURPOSE:To improve the withstand voltage of a field effect transistor without lowering Gm of the transistor by forming an ion injection region. CONSTITUTION:A junction type field effect transistor is composed of a P type silicon semiconductor substrate 21, an N type insular region 22, a P<+> type gate region 26 forming a channel region 25 by dividing the region 22 into source and drain regions 23 and 24, an N<-> type ion injection region 40, N<+> type source and drain contact regions 27, 28, an oxidized region 29, and source and drain electrodes 30, 31. When a depletion layer expanding toward the drain side of the region 26 reaches the region 40, it becomes ready to be expanded, and since it is expanded to an ion injected region 46 buried in the substrate 26, the concentration of the electric field is alleviated, and the withstand voltage between the gate and the drain can be improved.

Title: Concrete vibrator
Inventor: CHIKADA TAKUYA
IPC: H02P21/04
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To make defoaming rapid and restrain component separation of concrete from being accelerated by providing a motor rotating speed control circuit with a voltage detecting circuit, and rotating a motor at a high speed in case of detected voltage being the specified value or more and at a low speed in case of the specified value or less. SOLUTION: Concrete is placed and when an operation signal e8 is inputted to a microcomputer 6 to drive a concrete vibrator, voltage e9 proportional to a current flowing from a current detecting resistance 3a of a three-phase inverter 3 to a transistor rapidly rises to the maximum value. This voltage e9 becomes higher than a threshold voltage e11 showing the maximum value, and a high level signal e12 is outputted from a speed command switching circuit 72 so as to rotate the concrete vibrator at high speed, thus imparting vibrational energy required for defoaming. When the bubble quantity remaining in concrete is reduced, the voltage e9 is lowered. When the voltage e9 becomes lower than the threshold voltage e11 , a low level signal e12 is outputted from the switching circuit 72 to rotate the motor at a low speed.  Concrete can therefore be placed in a short time even by an inexperienced person.

Title: Warming device for stream regulating valve
Inventor: TSURUYA HIDEO
IPC: F01D17/10
Filed: 1986-04-04
Abstract: PURPOSE:To reduce a warming time, by determining whether a steam regulating valve is to be warmed or not in accordance with the differences among the steam temperature at the outlet of a boiler and the outside wall temperature and the outside ambient atmospheric temperature of the stream regulating valve and controlling a parallel valve disposed in parallel with a main steam stop valve. CONSTITUTION:When a steam regulating valve disposed upstream of the steam inlet of a turbine is controlled by a warming unit 18, a heat transfer calculation unit 19 calculates the inside wall temperature TI of the regulating valve and the outside temperature TE of the regulating valve when a parallel valve 3 disposed in parallel with a main steam stop valve is fully opened based on the temperature TB of the steam to be taken from the outside at the inlet of a boiler, the outside ambient atmospheric temperature TA of the regulating valve and the thermal flow quantity q of the steam at the outlet of the boiler. Then, TI is subtracted (20) from TE for determining a temperature difference between the inside and outside walls of the regulating valve to determine (21) whether the difference exceeds the limit value at which thermal stress is produced by the regulating valve. When the determination is YES, an opening for warming of the parallel valve 3 is calculated (22) for controlling the opening of the parallel valve 3 through a opening converter 24.

Title: Sewing machine
Inventor: KOJIMA MASATOMO
IPC: D05B73/00
Filed: 1993-04-02
Abstract: PURPOSE:To provide a sewing machine which can reduce noises generated by the vibration of a mechanical structure. CONSTITUTION:A frame 2 of a sewing machine has a natural vibration mode at a certain natural frequency. In a figure, a broken line shows a state before a deflection and a solid line shows a deflected state during vibration. In the natural vibration mode, there is a portion (node) which is not practically displaced as illustrated by circular marks in the figure. A cover is fixed to the frame near a point correponding to the node of natural vibration. It follows that even if vibration is generated by a mechanical motion such as a reciprocating motion of a shaft and balance or revolution of a motor and the frame is oscillated by the vibration the magnitude of vibration propagated from the frame to the cover is small, and hence the noise generated in the air near the cover can be restrained.

Title: Block controller for trackless carrier
Inventor: MURATA HITOSHI
IPC: G05D1/02
Filed: 1986-04-03
Abstract: PURPOSE:To improve flexibility of the route constitution as well as the operating efficiency with a trackless carrier by discriminating the passing conditions of a blocked area from the pass route of the carrier without providing any special sensor for block control at a point near the blocked area. CONSTITUTION:The position information are collected successively from carriers T1-Tn via the communication means 11 and 1 set one the ground and on the carrier. These carriers T1-Tn transmit the information on the blocked position where they themselves exist and the information on the scheduled driving routes when a marker is detected. Thus the ground station 11 can know a specific carrier existing in a blocked area and whether or not this carrier has possibility to interfere another carrier. Then the station 11 gives a drive permitting command to one of two carriers having possibility of mutual interference together with a drive inhibiting command given to the other carrier. This inhibition is released when no possibility of the mutual interference exists any more. In such a way, an individual command is given by radio to each carrier for drive control while grasping the situation. As a result, the problems of facilities are decreased despite approximation to the blocked area together with no deterioration of the drive efficiency. Furthermore the drive route can easily be changed with simple facilities set on the ground.
