Title: Clutch mechanism for driving cleaning device
Inventor: NAKAMURA TOSHIYUKI
IPC: F16D27/108
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To obtain a large torque transmitting force and to prevent failure from being caused in spite of long-time consecutive use by allowing a solenoid to move a can and allowing the cam to apply specified force to a coupling means. SOLUTION: An input side gear 12 and an output side gear 13 are arranged on the same rotary shaft. In a state where the solenoid 23 is not energized (state where a current is not supplied to the solenoid 23), an actuator 24 is extended and a cam 20 is in a state where it does not apply the specified force to the gear 12. Meanwhile, the solenoid 23 is energized, the actuator 24 is contracted and one end of the cam 20 is drawn. Thus, the cam 20 is turned centering a fulcrum 21 so as to press the gear 12 by the specified force. The specified force is made stronger than the elastic force of a spring 19, and the gear 12 is displaced to the gear 13 side against the elastic force of the spring 19. As a result, a 1st coupler 16 and a 2nd coupler 17 are fit each other and the gears 12 and 13 are synchronously rotated.

Abstract: PURPOSE:To make pictures and sounds periodically appear even when random access search is repeated, by making the squelch time accompanied with the random access search always constant by means of a timer means installed in a data processing means aside from the time required for reaching a track to be searched. CONSTITUTION:A signal reproduced at a video signal processing circuit 5 is inputted into a data sampling circuit 12 and address data are sampled at the sampling circuit 12. The address data are, for example, in the case of VHD system, recorded in specified horizontal scanning sections 17H and 18H or 280H and 281H in the vertical blanking period of video signals and they can be sampled by gating the specified sections by means of an appropriately generated clock pulse. The sampled address data are given to a control device 13 after they are converted into binary signals of ''0'' and ''1''. The series of operations at the time of random access are stored in the ROM of a microcomputer installed in the control device 13 as a software program. By the program the time until squelch is performed after the search key of random access is operated can be controlled so that the time always becomes a fixed time T.

Abstract: PROBLEM TO BE SOLVED: To increase the amount of air to be returned to a floor suction implement with a decrease in flow resistance in a return passage, without increasing the size of a cleaner body and an electric blower. SOLUTION: A body side return passage 19 in a body case 11 to cause the flow of air to be returned to a suction part and a suction part side return passage 7 is formed in the suction part 2 in communication with the body side return passage 19. The sectional area of the body side return passage 19 is equal to or larger than the sectional area of the suction part 2 so that flow resistance in the body side return passage 19 is smaller than suction resistance in the suction part side return passage 7. As a result, the amount of air to be returned to a floor suction implement is increased with a decrease in flow resistance, without increasing the size of a cleaner body and an electric blower.
