Title: Controller for ac motor
Inventor: TANAKA OSAMU
IPC: H02P27/06
Filed: 1987-12-18
Abstract: PURPOSE:To stably control a device in a low speed range, by controlling a converter with a current reference on which arithmetic is performed separately based on a voltage reference and a voltage detecting value, when the voltage detecting value on the output side on an inverter is a specified value or less. CONSTITUTION:When the output voltage V of an inverter circuit 5 comes to a value or less corresponding to a specified speed between a low speed range and a mean speed range, then by a switching circuit 20, its contact is switched, and in place of the current reference I1 of a current reference arithmetic circuit 15, the current reference I1 of a voltage controlling circuit 19 is supplied to a current controlling circuit 17. At the same time, the circuit of the phase difference signal beta of output generated from the current reference arithmetic circuit 15 and applied to a current controlling circuit 18 is separated. As this result, the output current of the current reference circuit 15 is controlled independently of a phase angle, and so a stable operation is performed even in a low speed range.

Title: Image processor
Inventor: SUZUKI HIROAKI
IPC: G09G5/36
Filed: 1991-11-08
Abstract: PURPOSE:To obtain an output image which does not tilt to the sides of an output form by making skew adjustments when new data are filled in source image data. CONSTITUTION:Read data showing an actual image which is read in by a scanner are saved on a HDD, and a specified area is a rectangular area encircling the figure. Rough skew adjustments are made according to characters 'a, ka, sa' forming the edge part of the read area and a scan is made in a (y) direction. From the intersection C0 of the bisectors of the sides of the rectangular area satisfying sections a0-a1 and b1-b0 of 'a' and the similar intersection C2 of 'sa', the angle theta of the straight line 1 passing two points to the Y axis is calculated and the rotation result based upon an obtained correction angle theta0 is written on a memory HDD for temporary storage. In this case, a virtual line slopes and the correction is incomplete, so fine skew adjustments are made. Thus, the skew processing is performed and then the source image data are rotated and outputted.

Title: Tester for protective relay
Inventor: FURUKAWA OSAMU
IPC: H02H3/28
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To enable the automatic setting of a computed value by making the slip velocity between a fundamental wave and a higher harmonic wave the velocity where the slip angle does not get over the tolerable value, and besides, making the sweep velocity of the higher harmonic wave the velocity where the signal level variation value does not get over the tolerable value. SOLUTION: In case the fundamental wave is 50Hz, the oscillatory frequency f1 of a fundamental frequency generator 1 is set to 50Hz, and a signal adjuster 1a is set so that the output current of a current amplifier 1b may come to a stipulated value. Next, the oscillatory frequency f2 of a higher harmonic wave signal generator 2 is set, but it is set, being slid a little from the oscillatory frequency f1 of the fundamental wave signal generator 1, and a series of operations such as operation, etc., are computed with CPU4, using the value of operation/return time of a protective relay 3 to be tested, stored in a storage 4b.  Moreover, in the case of automatically measuring the operation/return value by automatically sweeping the current value thereby changing it, this automatically reduces the applied current value with its current sweeping function from nonoperation state, and indicates the applied current value on a display 4c at the point when a contact S operates. As a result, the automatic computation and setting of the slip velocity and the sweep velocity become possible.
