Title: Speed control device of motor
Inventor: WATANABE MASAHIKO
IPC: H02P29/00
Filed: 1987-07-22
Abstract: PURPOSE:To allow a motor to be controlled stably and precisely, by letting a speed estimate value be a feedback signal when no output of a position detector varies for the time longer than a sampling period. CONSTITUTION:A current command value Ir is calculated using a speed command value Nr and a speed feedback value Nf by a speed control operation 2 of a microcomputer 1. A pulse Ep generated by an encoder 9 is converted into a rotating speed detection value Nd and a rotating position detection value Pd by a positional speed detection circuit 10, a speed detection operation 3 and a position detection operation 5. A speed estimate operation 4 determines a speed estimate value Nd' in accordance with a current command value Ir, a speed detection value Nd and a position detection value Pd. A speed feedback signal Nf is changed over to a speed estimate value Nd' in a low speed when no output pulse of the encoder 9 will come to change in a sampling period of speed control.

IPC: B21D24/04
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent a base material from cracking by using a pressing force of a variable point bead and forming the material by means of a punch while suppressing the generation of cracks. SOLUTION: A base material 11 is clamped by a blank holder (wrinkle holder) 2 and a die 1, an opposed die. With the die 1 lowered further, the blank holder 2 is also lowered, so that the base material 11 is drawn into the recessed part by the punch 4 to complete forming. In this case, the pressing force of a variable point bead 5 is used against the base material 11, on an arbitrary part of the material during the forming, selectively for the period, and also in points. As a result, the base material 11 is formed by the punch 4 while cracking is suppressed in the material 11. In addition, the material 11 is pressurized and retained by the blank holder 2, fixed bead 3 and opposed die 1. Thus, the blank holder or its opposed-die, even with complicated shapes, can be easily assembled into the blank holder or the die.
