Abstract: PURPOSE:To exclude the effect of internal noise by selecting the amplification factor of the 1st and 2nd amplifiers nearly equally and selecting the said amplification factor respectively in a manner that the internal operating voltage of the 2nd integration device is a prescribed number of times of an analog input signal voltage or below.

Title: Method for controlling motor
Inventor: TAGOME MASAKI
IPC: H02P21/02
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To control a motor so that the motor is not braked with regenerative torque when a small torque instruction is given by changing the gain which decides the increase/decrease of the value of a d-axis current command of a permanent magnet in accordance with a commanded current for motor which is calculated at every fixed period at the time of performing field weakening control correspondingly to the commanded current. SOLUTION: When an accelerator full-close detecting switch is closed, the q-axis current of a motor which is perpendicular to the d-axis current of the motor and the daxis current are computed and outputted to the motor as a regenerative mode. When the detecting switch is opened and the electric signal corresponding to the opening of an accelerator is not zero, the q- and d-axis currents in a power running mode are computed. The gain which decides the increase/decrease of the d-axis current controls the commanded current of the motor so that the current may become a small value and, when the motor is affected by field weakening in a high rotating speed region, may become a large value.  In the power running mode, therefore, the gain which decides the increase/decrease of the d-axis current command value becomes larger even when the commanded current of the motor becomes smaller and the d-axis current command value itself maintains the torque generated in the power running direction. The gain is changed so that the gain may not become discontinuous in a coasting, regenerative, and power running modes.

IPC: G01P3/80
Filed: 1984-11-14
Abstract: PURPOSE:To measure the length of as rolled material by measuring the speed of the rolled material being rolled and calculating the length of the rolled material on the basis of the speed. CONSTITUTION:The red hot rolled material 10 sent out of a finish rolling mill 12 is passed by photoelectric converting elements 14A and 14B installed at reference positions A and B to detect the radiant energy corresponding to the surface temperature. This energy is converted by the elements 14A and 14B into electric signals, which are sent to a mutual correlation computing element 16. This computing element 16 calculates the coefficient of correlation between the detection signals of the positions A and B and find the time difference between A and B from the maximum value. Then, the speed of each section wherein the rolled material 10 is present is calculated from the distance and difference between the positions A and B. Further, the passing time is measured by a rolled material passing time measuring machine 18 from the signal of the tail detection of the rolled material 10 at the position B. Then, the speed is calculated repeatedly at intervals of a certain time and the length of the rolled material is calculated in a certain section from the product of the speed and passing time of the rolled material; and this value is integrated to calculate the overall length of the rolled material 10.
