Title: Control of brushless motor
Inventor: OHARA YOSHIYUKI
IPC: H02P6/18
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To lessen possibilities of abnormal stoppage of a brushless motor due to a bad start-up and make it possible to surely shift to a position detecting operation mode by confirming that the motor has started up stably when starting up the motor using a position detecting operation and a synchronous operation. SOLUTION: A controlling circuit 11 supplies a predetermined voltage to a brushless motor 4 and starts it up, After it starts up the motor, it detects the position of a rotor based on output position detection signals of a position detecting circuit 10. Each time the position of the rotor is detected, the current conduction of armature windings U, V, W of the brushless motor 4 is switched. If the position cannot be detected within predetermined period of time, the current conduction of the armature windings is forcibly switched. When the conduction is switched at a given number of times and then an operation mode is shifted to a position detecting operation mode, the stability of rotation checked, based on the information (whether the position detection has been conducted, intervals of position detections, etc.) so far. When the rotation is judged unstable, the motor is restarted.  When the rotation is judged stable, the operation mode is shifted to the position detecting operation mode.

Title: Injection pressure controller for die casting machine
Inventor: KUBOTA MASAMITSU
IPC: B22D17/32
Filed: 1990-04-27
Abstract: PURPOSE:To avert the pressure increase in succession to the stop of an injection side cylinder and to eliminate a packing surge without dropping the packing pressure of a hydraulic source by monitoring a means for detecting the completion of the packing by a control means and closing an injection side stop valve on the spot when the completion of the packing is detected. CONSTITUTION:A timer 32 started on detection of the completion of the packing counts the prescribed time in the control means 30. A solenoid valve 37A is opened by the control means 30 upon ending of the counting, by which a pressure increase side stop valve 26 is opened and a cylinder 27 for pressure increase is moved by the oil pressure from a pressurizing circuit 25 for pressure increase. The pressure increase is thus executed. The pressure increase stroke is ended by maintaining this state for a prescribed period of time, by which the molten metal 14 in a cavity 2 is sufficiently pressurized and the molding is completed. The injection pressure is increased by the high-speed injection but the oil pressure on the injection side is shut off on the spot when the packing is completed by the injection side stop valve 24 and, therefore, the generation of the packing surge, etc., is prevented.

Title: Shape control method of strip
Inventor: NAGANUMA YOUICHI
IPC: B21B37/42
Filed: 1978-09-19
Abstract: PURPOSE:To obtain sufficient control performance against complicated shape defects in a simple control system, by finding the deviation between target value and detected value of symmetric and asymmetric parameters, and adjusting the operation end by comparing the evaluated values obtained from said two values, target value and estimated value. CONSTITUTION:A shape pattern signal of a plate 1 in the breadthwise direction sent from a shape detecting device 31 at the exit side of a rolling mill possessing intermediate rolls movable in the axial direction is divided into two parameters, symmetric and asymmetric, by a recognition device 32. The deviation between the detected value and the target value is obtained in a device 34, and a device 5 determines the evaluation value by evaluation function from said both values of symmetric components. Estimating the shape change in the case of varying the set point, an estimated value is obtained, and the evaluation is determined from this estimated value and the target value, and is compared with said estimated value to set and correct the intermediate roll position and roll bending force. Processing the asymmetric components similarly, the screw-down position difference between the operation side and driving side, rool bending force difference, or  intermediate roll position difference can be set and corrected. Repeating such operations, the  shape control is achieved.
