Title: Slider of zipper
Inventor: TAKEMOTO MASAHIRO
IPC: A44B19/26
Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To prevent a matter from being biting between a guide member and opening and closing teeth by forming the guard member in the front part of one base member of a slider so as to be extended forward. SOLUTION: A zipper has a guard member 13 in the front part of a reverse base member 8 to eliminate a matter to bite between opening and closing teeth 4, 5 in advance by the guard member 13. A slider 6 introduces the opening and closing teeth 4, 5 fixed on a lateral pair of cloths 2 by operating an operating tab 10. The opening and closing teeth 4, 5 are mutually engaged to connect the cloths 2 through the geared opening and closing teeth 4, 5. Since the guard member 13 is attached on the front part of the reverse base member 8, a matter to bite between the opening and closing teeth 4, 5 and the slider 6 is eliminated by the guard member 13 so as not to be pulled into the slider 6. Consequently, the smoothly connected cloths are delivered from the rear side of the zipper without causing an operation failure by the biting of the matter into the slider 6.

Abstract: PURPOSE:To prevent vibration in the case when a motor is decelerated or stopped by controlling an inverter drive circuit by means of a discriminator, output thereof reaches an H level when both output voltages of a speed setter and an input limiter reach some value or lower. CONSTITUTION:An induction motor 16 is connected to a converter 14 and a transistor bridge circuit 15, and operated by means of a speed setting system changing the signals of a stopped variable resistor 1 for setting speed into signals, which change at a fixed gradient, by means of an input limiter 2.

Abstract: PURPOSE:To permit the power running of train passing and to prevent the temporary power interruption of train by providing a phase detector, a train position detector, and a phase shifter to a power source switching device in the connecting part of a trolley wire receiving power from different AC power sources. CONSTITUTION:When a train 10 runs in the direction of arrow A over the section of a trolley wire 5, a train position detector 14 sends out a signal corresponding to ''none'' of the train and a phase shifter 17 synchronizes the voltage phase of the trolley wire 7 with that of the trolley wire 5, and thereby the train 10 passes through the section 8 in power running state. Then, when the train 10 passes through the section of the trolley wire 7, a signal corresponding to ''existence'' of train is added to the phase shifter 17, the voltage phase of the trolley wire 7 is synchronized with that of the trolley wire 6, and the train 10 runs in power running state in the section 9. Subsequently, when the train 10 starts to run in the section of the trolley wire 6, the phase shifter 17 varies again the voltage phase of the trolley wire 7 and holds the voltage of the trolley wire 5. Thus, the power interruption of the train 10 can be avoided.
