Title: Power-factor controller for synchronous motor
Inventor: KISHIMOTO FUJIO
IPC: H02P23/00
Filed: 1978-08-04
Abstract: PURPOSE: To automatically control the power-factor of a synchronous motor to a maximum phase-advancement value by the signal of a calculation circuit, by detecting the current of an armature circuit, comparing the current with a setpoint and applying the difference and the signal of a field current detector to the calculation circuit.  
     CONSTITUTION: The main circuit current Ia of the synchronous motor 1 is detected by a current transformer 4 and compared with the signal of a rated current setting unit 7 by a comparator 8. The difference is applied to an operational amplifier 15. The current If of the field winding 2 of the motor 1 is detected by another current transformer 12 and applied to the operational amplifier 15 through a limiter 14. The calculation circuit detects such an optimal driving current level that the power factor of the motor has the maximum phase-advancement value. The calculation circuit applies a signal ΔI to a phase shifter 16, which generates an output signal to control a thyristor 3 to sulply an appropriate driving current to the motor.

IPC: A47C17/32
Filed: 1994-05-09
Abstract: PURPOSE:To make a bed device easy to use and to improve appearance and performance by holding an auxiliary mattress at the same height as that of a main mattress by a link mechanism and arranging an auxiliary head board movably freely. CONSTITUTION:An auxiliary bed 2 is arranged in such a way that it can be drawn in/out from a housing part 5 formed on the main bed frame 3 of a main bed 1. When it is housed, the auxiliary mattress 2 is descended in a state to be housed in the housing part 5 by the link mechanism 15, and when it is drawn out, the auxiliary mattress 21 can be held at the same height as that of the main mattress 6 by the link mechanism 15, to make it easy to use. Also, the auxiliary head board 32 of the auxiliary bed 2 housed in the back plane side of the main bed board 31 of the main bed 1 is drawn out integrally, which provides superior appearance and prevents a head side from being directly exposed to the wind. When this device is used for single, since it can be used in a state that the bed frame 8 of the auxiliary bed 2 and the head board 32 can be prevented from being exposed to the outside, the performance and the appearance as a bed for single can be prevented from being impaired.

Title: Method for reproducing mask for organic film vacuum deposition and device therefor
Inventor: TAKAKURA HIDEO
IPC: C23C14/04
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To easily remove an organic film deposited on a mask without using etching by plasma and without breaking a vacuum by subjecting the organic film to heating treatment. SOLUTION: Since an organic film is evaporated or sublimated at a relatively low temp. (about <=300 deg.C) in a vacuum, by heating the mask to a temp. higher than the evaporating temp. or sublimating temp. of the material deposited on the mask, the film can be removed. The evaporated content of the film deposited on the mask redeposits on a part low in temp. of a deposition preventive board or the like. Furthermore, in the case there is a shutter for preventing radiation heat directly above an evaporating source crucible, the organic material in the crucible does not evaporate. Since the exchange of the mask at the time of maintenance is not required, the positioning of the mask may be executed only at the time of its setting at first. For heating the mask, a method of using a heater capable of radiation heating or conduction heating, a method of directly flowing electric current through the mask and generating Joule heat, a method by induction heating, or the like, can be given.

Abstract: PROBLEM TO BE SOLVED: To enable work execution without removing construction girders so as to extremely simplify construction, and divide operations switching to ballast finally constructed and ties finally constructed or the like into one day's worth of work execution mount so as to achieve economical performance rich in rationality. SOLUTION: A saddle 5 is positioned for receiving a construction girder 1, and the girder 1 is lowered according to the slope in order to align a rail track height to a track height finally constructed. In addition, the construction girder 1 is lowered again by a distance equivalent to the difference between the height from the construction girder 1 top end to a rail 3 top end and the track height finally constructed (from a road-bed bottom end to a rail top end). At this time, a rail sleeper girder is inserted between the construction girder 1 and a tie 2 so as not to change the rail top end. After a second lowering of the construction girder 1, concrete is filled up to the construction girder 1 top end to be buried. Afterwards the tie 2 and the tie girder are removed, and road-bed ballast and a tie finally constructed are installed.

Abstract: PURPOSE:To make thin an insulating film under a select gate electrode, to thicken an insulating film between a floating gate electrode and the select gate elctrode easily and to enable low program voltage without shortening the life of the storage of a memory by using a silicon nitride film as a gate insulating film for the PACMOS memory. CONSTITUTION:A gate insulating film for a channel L2 under a floating gate electrode 14 is formed by a silicon dioxide film 16 and a silicon nitride film 17, and a gate insulating film for a channel L1 is shaped by a composite film consisting of an insulating film composed of the film 16 and the film 17 formed at the same time as the gate insulating film for the channel L2 and an oxide film 18 of a nitride film shaped at the same time as the floating gate electrode 14 is oxidized.
