Title: Power converter for a.c. electric locomotive
Inventor: NOZAKI YOSHIO
IPC: H02M7/12
Filed: 1978-11-06
Abstract: PURPOSE: To diminish the change of electric current in motor at the instant of voltage change- over, by effecting the change-over of the voltage during the power running at a moment when the  control angle has come into the range of overlapping angle and effecting the change-over of the  voltage during regeneration at a moment when the control angle and the overlapping angle have  come to take predetermined values.   
     CONSTITUTION: Thyristors 7, 8, 11, 12 connected to the secondary side of the transformer 3 are  used in the same manner as diodes during the power running, to effect a phase control of thyristors 6, 9 to obtain output voltage E 1 . When the control phase angle α of the thyristors 6, 9 come  to take the minimum value to provide the maximum level of the output voltage E 1 , the control  angle of the thyristors 6, 9 is instantaneously increased to the maximum level and, and the same  time, a signal is delivered to thyristors 10, 13 of an on-off control unit to provide the minimum  control angle and the maximum D.C. output E 2 . No change of total voltage E 1+2  is caused at the  moment of change-over of the control unit. Thereafter, an electric motor 15 is driven by the total  voltage with the control angle of the thyristors 6, 9 taking the maximum level. In the attached  Figures, Sm and Sc represent, respectively, the output from a minimum phase angle detector and  a control unit change- over signal. The total voltage E 1+2  overlaps the control angle and the  change-over is made at a moment when the angle u has become constant.

Title: Liquid crystal display device and its production
Inventor: IWAMOTO TAKASHI
IPC: G02F1/1341
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to shorten the filling time of liquid crystals without providing the process with a fresh stage and without affecting display characteristics. SOLUTION: This process for production consists in providing a filling port 3a with a closed loop pattern 3b formed by a sealing material 3 near the port and providing the inside of a liquid crystal display panel with a closed space 4. If the liquid crystal display panel is formed under an atm. pressure environment, the pressure in the closed space 4 is maintained under the atm. pressure. If filling is executed by a vacuum filling method in this state, the inside of the liquid crystal display panel is evacuated from the filling port 3a as the pressure in a vacuum chamber is reduced but the closed space 4 is inflated by the pressure difference from the outside. The state is the state that the gap of the filling port 3a is widened and is, therefore, convenient for the evacuation in the liquid crystal display panel.  The evacuation time in the liquid crystal display panel may thus be drastically shortened.

IPC: B23K9/12
Filed: 1985-06-25
Abstract: PURPOSE:To obtain sufficiently uniform weaving by the small number of teaching point inputs by inputting weaving data only at a point where a weaving operation pattern is changed. CONSTITUTION:At the teaching of a point P1, weaving auxiliary points W11, W21 are inputted, so that the direction and amplitude of weaving at the point P1 are set up and the 1st operation pattern in an area 1 from the point P1 to a point P3 is regulated. Therefore, inputs such as auxiliary points W12, W22 are unnecessary at the points P2, P3. In an area 2 from the point P3 to a point P5, the weaving pattern is different and the 2nd operation pattern is adopted, so that auxiliary points W13, W23 are teached at the point P3 to specify the weaving operation pattern in the area 2. Once the auxiliary points have been teached, the weaving of the 2nd operation pattern is executed in the area 2 until the succeeding auxiliary points are newly teached.

Filed: 1988-06-02
Abstract: PURPOSE:To prevent the occurrence of nonconformity such as a traveling clutch is not disconnected at the time of a neutral operation by controlling an actuator for continuous variation based on an operating position memory means during the time when a prescribed operation such as the throw-in of power source, etc. at the start of an engine is to be carried out next. CONSTITUTION:At the time of carrying out a predetermined operation such as the throw-in of power source, etc. at the start of an engine, an actuator 25 for continuous variation is forcedly operated to the most contracted position based on a forced contraction operating means 38. The detected value of an operating position detecting means 26 at the point of time when the actuator 25 is contracted to the most contracted position is inputted into an operating position memory means 34 to carry out renewal. The actuator 25 is controlled based on the renewed and inputted value by this operating position memory means 34 until the next prescribed operating time. Therefore, when the reference value of the detecting means 26 is shifted to, e.g., the expanding direction or contracting direction of the actuator 25, there will occur no nonconformity such as the actuator 25 is not contracted to the most contracted position without disconnecting a traveling clutch in spite of carrying out a neutral operation.
