Title: Controller for valve actuator
Inventor: UCHIYAMA MAKOTO
IPC: H02P29/02
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To cope with abnormal situations by arbitrarily changing the rotation speed of a motor by a signal from a speed sensor, quickly stopping the rotation of the motor and detecting condition at this time, when the motor is constrained by some reason or other and a valve is out of control. SOLUTION: When a motor 14 is started, a voltage U1 outputted from a speed-voltage converter circuit 3 is low, however, an OR circuit 8 is operated by the input of one-shot pulse from a pulse generator circuit 7 and outputs a rotation command signal U4. When the rotation speed of the motor 14 reaches a set rotation speed, the OR circuit 8 continuously outputs the rotation command signal U4 and continuously energizes to the motor 14. The rotation speed of the motor 14 is monitored by a speed sensor 2 at all time so as to be held at a fixed speed by changing the output torque of the motor 14 according to the load. When the rotation command signal U4 is not outputted for some reason such as the valve is in an overloaded state, an energization control circuit 6 interrupts the energization to the motor 14 and outputs a signal of the occurrence of an abnormal situation.

Title: Motor controller
Inventor: HARA TAKASHI
IPC: H02P6/20
Filed: 1990-03-09
Abstract: PURPOSE:To make the hysteresis width BW of a magnetic sensor apparently wider and eliminate the influence of the variation of the hysteresis width BW of the magnetic sensor by a method wherein a pulse generator generating a negative pulse is connected between both the terminals of a current limiting device inserted between the magnetic sensor and a switching device. CONSTITUTION:By a signal from a pulse generator 15, a current is applied to a coil 5 for a period longer than a hysteresis width BW between a detection level BH-L at which a magnetic sensor 7 is turned from detection-OFF to detection-ON and a detection level BL-H at which the magnetic sensor 7 is turned from detection-ON to detection-OFF. If a rotor 2 yields to the repulsion force of an initial positioning magnet 6 and starts reverse rotation after the attraction force of the coil 5 is lost at the level BL-H, the rotor 2 is restored to a position of the level BH-L and starts normal rotation again by the attraction force of the coil 5. After such processes are repeated several times, the rotor 2 overcomes the repulsion force of the initial positioning magnet 6 by an acceleration obtained during a period between the levels BH-L and BL-H and during the period of the width of a pulse from the pulse generator 15.

Title: Manufacture of roller having varying diameter
Inventor: MATSUURA MOTOO
IPC: B29C39/00
Filed: 1987-03-12
Abstract: PURPOSE:To obtain a smooth roller, which varies in diameter axially and on the outer peripheral surface of which no parting line mark due to the molds is produced, by a method wherein a double tube, the outer tube and the inner tube of which are connected to each other by a connector at the middle in the axial direction, is molded and cooled so as to contract both end parts, resulting in making the diameter at the end part smaller than that at the middle part of the tube. CONSTITUTION:A double tube 8 consists of an outer tube 9 and an inner tube 10, both of which are concentric, and an annular connector 12, which connects both the tubes 9 and 10 at the middle part 11 of the tube 8. After being released from a mold, the double tube 8 is cooled and finally cooled to normal temperature. The synthetic resin molded form shrinks is proportion to the wall thickness. Since the thin connector 12 is formed at the middle part 11 of the double tube 8, the shrinkage of the connector is smaller than that at the remaining part. Accordingly, the middle part 11 is restricted by the connector 12 and both end parts 13 perform the stress due to shrinkage action, resulting in realizing a barrel-shaped roller varying in diameter so as to gradually reduce the diameter from the middle part 11 to both the end parts 13 in the axial direction.

Filed: 1989-03-10
Abstract: PURPOSE:To prevent the damage of an component caused by the movement action of a main axis by movably installing an automatic tool exchange device along a direction of the main axis for approaching to the automatic tool exchange device. CONSTITUTION:When a main axis 20 is ascended as shown with a chain line from the normal position of a continuous line by manual operation in order to exchange a tool 100, the axis 20 abuts the tool 100, and an automatic tool exchange device ATC 10 is swingingly moves from the normal position of the continuous line to the chain line position. As a result, the movement of ATC 10 is detected with an approach switch 8, and the axis 20 is controlled so as to automatically stop an ascent. In this case, the axis 20 is dlightly ascended by inertia until the axis 20 is actually stopped with the movement of ATC 10 detected with the switch 8, however since ATC 10 swingingly moves together with the ascent of the axis 20, damage is unoccurring in both ATC 10 and the axis 20. And when the axis 20 is lowered after the stop of it, ATC 10 can be easily returned to its normal position with its dead weight.
