Title: Vector controller for induction motor
Inventor: YAMADA TETSUO
IPC: H02P23/07
Filed: 1989-04-13
Abstract: PURPOSE:To compensate for secondary resistance fluctuation by converting detected values of primary current into orthogonal coordinate components having reference axes lagged by the power factor from an output voltage vector, and then operating secondary resistance fluctuation based on the converted values of primary current and correcting the set value of secondary time constant based on the secondary resistance fluctuation. CONSTITUTION:A power factor operating section 14 operates power factor psibased on current command values i1alpha*, i1beta* and an output angular speed omega. A three-phase/two-phase converting section 10 converts detected values iu, iw of primary current into alpha1, beta1 coordinate components i1alpha1, i1beta1 based on the primary flux phase phild and the power factor psi. A matching circuit 15 matches the detected current value i1beta1 to a reference value(=0) corresponding to the current command value i1beta1* thus obtaining the difference. A PI amplifier 13 carries out proportional integration of the difference and outputs the integration result as a secondary resistance fluctuations K. Thus obtained secondary resistance fluctuation K is employed in a slip angular speed operating section 7 where operation for compensating for secondary resistance fluctuation is carried out.

Title: Water level controller with continuous draining function
Inventor: SHIGEKUNI TOSHIKI
IPC: F16K21/16
Filed: 1980-07-10
Abstract: PURPOSE: To enable every member to prolong the span of their life ever longer by passing water through a bypass in time of draining without operating impellers and avoiding the imposition of an intolerant load upon a member when continuous draining takes place.  
     CONSTITUTION: When rotating a control dial 10 counterclockwise, both control levers 14 and 17 are pushed by a setting part 22 for continuous draining of a cam face 13, opening a stop chamber 4 and at the same time a valve 21 is shifted to the waterway side where an impeller 6 exists, connecting the waterway to the stop chamber 4 through. Therefore, the impeller need not be rotated whereby the impeller 6 and speed reducer trains 7 and 8 rotate only when automatic water stopping takes place, meaning that no load is imposed upon the members. Thus the prolongation of each member's life can be much expected.

Title: Uneven thickness preventing method in mandrel extrusion
Inventor: HASHIMOTO ICHIRO
IPC: B21C23/08
Filed: 1991-04-24
Abstract: PURPOSE:To prevent the uneven thickness and to extrude a mandrel extrusion tube with high precision and efficiently. CONSTITUTION:This method uses a bottomed semihollow billet 10 in which a mandrel insert-through hollow part 10a is formed in the bar line direction, and also, the front end part in the extrusion direction of the hollow part is a solid part 10b. When a mandrel 2 advances to a correct position, a forming gap 8 between a die bearing part (3a) and the mandrel 2 is filled with the solid part 10b. As a result, the mandrel 2 becomes a both end supported state supported in not only the rear end part but also the front end part, therefore, even if an uneven load works at the time of expansion of the diameter of the billet, the mandrel can stand it enough, generation of bending of the mandrel 2 is suppressed, and uneven thickness of an extruded stock is suppressed.

Filed: 1981-06-17
Abstract: PURPOSE:To obtain a ternary swich at a single power supply, by controlling the output of a circuit which detects the state of low or high level of an input signal, through the output of a circuit which detects the periodicity of the input signal. CONSTITUTION:When an input signal Vs is at a low level, an FET15 turns on and capacitors CS and CH are discharged with a resistor 18. Thus, the output X of a gate 13 goes to ''1'', the output Y of a gate 16 gors to ''0'' and the output Z of a gate 17 goes to ''1''. Since the FET 15 turns off and the capacitor CH is discharged when the input signal Vs goes to a high level, the X goes to ''0'', the Y goes to 21'' and the Z goes to ''1''. When the input signal is a periodical signal, FETs 14 and 15 are alternately turned on and off, the capacitor CH is gradually charged and the output Z of the gate 17 goes to ''0''. Thus, the X and Y go to ''1''.

Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To eliminate turbidity of right/left information and to provide a polarizing spectacles-type three-dimensional picture which can simultaneously be obtained for plural persons with less annoyances by synchronously operating the vertical scanning of a liquid crystal display device and a polarized axis conversion device to three- dimensional display of the image. SOLUTION: Since light output becomes a linearly polarized light in a general TN liquid crystal display device. TN liquid crystal is used for a polarizing plate in a polarized axis conversion device 3 which is divided into four in a vertical direction. The device is 90 degrees polarized, with voltage is turned off. When the voltage is turned on, light is transmitted at 0 degree, and a polarized axis is converted. Then in an upper 1/4 region, a conversion is started from the start of vertical scanning and the polarized axis is converted by executing synchronization, so that the conversion of the polarized axis for the field terminates when scanning terminates. In a 3/4 period excepting the period of 1/4, the left eye video of an n-field reaches an observed through the left eye polarized axis.  A right eye video so led by a right eye polarized acid in the 3/4 period in the next n+1 field and a three-dimensional image is displayed. Thus, the polarized axis conversion device is divided in the vertical direction and is operated, while synchronizing with the screen scanning and the image is displayed three-dimensionally by a holding-type display device.
