IPC: H02P23/00
Filed: 1978-12-26
Abstract: PURPOSE: To protect a reverse converter automatically by detecting fall or abnormal decrease in power supply voltage and variations of power-supply frequency exceeding a specified value at the normal-supply voltage; and by preventing the commutation failure of the reverse converter.  
     CONSTITUTION: The secondary-side slip voltage of a wound-rotor type induction motor 20 is converted into DC by a forward converter 32, and connected to a power supply through a reverse converter 36 and a transformer 38. The difference between the actual value of a speed generator 44 and the objective value of a setting device 42 actuates a trigger controlling device 50 through a speed regulator 40, and the control lead angle of the reverse converter 36 is controlled. Furthermore, a secondary frequency is introduced into a control device 54 through the transformer 58, and the output of the control device 54 controls the reverse converter 36 and a thyristor 56 which is connected in parallel with a DC reactor 34. Therefore, the control lead angle of the reverse converter 36 can be automatically shifted to the minimum allowable angle at the time of emergency, and the reverse converter 36 can be securely protected.

Inventor: YOSHINOBV OHACHI
IPC: B29C48/10
Filed: 1985-07-19
Abstract: PURPOSE:To provide an annular thermoplastic resin film, the inner surface of which is roughened, by a method wherein molten thermoplastic resin is discharged annularly from a resin discharge port so as to hold the air in the interior of the resin in order to mold an annular thermoplastic resin film in such a manner as to form a coarse surface with uniform and fine ruggedness onto the inner surface of the film. CONSTITUTION:Blown-film extrusion is done by using a die 5 equipped with a cooling medium passage 7 formed in annulus along a resin discharge port 6 in the vicinity of the outer surface of a mandrel 1 located inside the resin discharge port 6 which communicates with a resin passage 3, of the die 5. In order to blown-extruded thermoplastic resin, molten thermoplastic resin is flowed in the resin passage 3 and, on the other hand, cooling medium is introduced from a cooling medium leading-in port 8 so as to circulate in the cooling medium passage 7 in order to annularly discharge the molten thermoplastic resin from the resin discharge port 6 under the state that only the outer surface located inside the resin discharge port, of the mandrel is cooled. In this case, when the cooling temperature of the inner surface at the portion which ranges from the lower end of the resin discharge port to the location 30mm or less in the axial direction from the lower end of the resin discharge port, is held lower by 5-60 deg.C than the outside temperature, especially excellent effect is obtained.

Filed: 1985-07-19
Abstract: PURPOSE:To improve the stationary position accuracy by switching from a high voltage to a low voltage in a decelerating stroke, and closing a switching element, thereby reducing the vibration at stopping time. CONSTITUTION:When a stepping motor is stopped at a stationary position, a transistor TR1 is turned OFF to switch a voltage applied to the winding L1 of a motor to the second motor driving voltage V2 lower than the first motor driving voltage V1 to reduce the driving torque of the motor, to rapidly converge an overshoot, and to turn ON a switching element SW1 to form a closed loop of the winding L1, a diode D7, the element SW1 and a diode D1, thereby forming a closed loop without a resistor R1. Thus, a potential difference between the both ends of the winding L1 momentarily becomes equal, a current i<3> due to an electromotive force generated in the winding L1 abruptly increases to abruptly attenuate a vibration.

Title: Piezoelectric vibrator
Inventor: SADAMURA SHIGERU
IPC: H04R17/00
Filed: 1986-07-08
Abstract: PURPOSE:To simplify a manufacture, to shorten a production process, to improve a quality and the reliability, and to increase a piezoelectric constant by providing a groove at a boundary part between the displacement part and the non- displacement part of a vibrating medium on which an electrode is mounted, in a piezoelectric vibrator in which both electrodes are arranged so as to oppose each other with a space on an approximate same plane on a free surface. CONSTITUTION:A groove 7 is made as deep as it does not damage the strength of the vibrating medium 1 between electrodes 2 and 3. The displacement part 11 and the non-displacement part 12 being divided apart by the groove 7, the displacement part 11 can easily vibrate. Consequently, even when a same voltage is impressed, a large displacement or a large vibration can be produced. Furthermore, in the case that it is used for a receiving element, the same displacement can produce the large voltage. And also, owing to providing the groove 7, a leakage capacity from the vibrating medium 1 comes extremely small, and then the capacitance C of the vibrating medium can be decreased for instance from conventional 34 pF to 27 pF. Accordingly, an induced voltage can be made large.
