Title: Vacuum cleaner
Inventor: MORI HIROSHI
IPC: A47L9/14
Filed: 1991-10-01
Abstract: PURPOSE:To obtain a vacuum cleaner equipped with a dust bag absence- preventive device which allows attaching a dust bag in the upper opening of a dust collecting chamber when a lid of the dust collecting chamber is turned but prevents it from being attached when the lid is slid into the dust collecting chamber from front. CONSTITUTION:When a lid 7 of a dust collecting chamber 2 is slid into the dust collecting chamber 2 with a dust bag unattached, a protrusion 14 of the lid 7 comes into contact with a contact part 18 of the dust collecting chamber 2 to keep the rear edge of the lid 7 from coming in close contact with the rear edge of the dust collecting chamber 2, so that a lock device remains unlocked. Thereby, the lid 7 is prevented from being shut, and a user notices that a dust bag should be attached. When the lid 7 is turned and set in the dust collecting chamber 2 after the dust bag is attached, the protrusion 14 is inserted in a recessed catch 16 of the dust collecting chamber 2 and the rear edge of the lid 7 comes in close contact with the rear edge of the dust collecting chamber 2 without the lid 7 loosened, so that the lock device engages. Thus, the lid 7 can be mounted on the dust collecting chamber 2.

IPC: G06F13/38
Filed: 1989-09-28
Abstract: PURPOSE:To change the connection of processors having different signal terminal arrangement by connecting a driver and a receiver to respective signal terminals, and judging the type of the signal terminal concerned by means of the analog voltage value of the output terminal of the drivers. CONSTITUTION:A control part 36 transmits an operation prohibition signal to the common terminal of a switch contact point 35, and the switch contact point 35 and a switch circuit 33 are switch-controlled. The drivers 30a and 30b and the receivers 31a and 31b are connected to respective signal terminals. Then, it is judged whether the drivers 30a and 30b or the receivers 31a and 31b are connected to the opposite terminal of the signal terminal concerned by the analog voltage of the output terminals of the drivers 30a and 30b. The drivers 30a and 30b or the receivers 31a and 31b corresponding to the type of an opposite-side is selected and used. Thus, the connection of the processors having different signal terminal arrangement can easily be changed without changing the connection of signal lines on a cable-side.

Filed: 1992-08-27
Abstract: PURPOSE:To coil a steel strip under tension without forming a steel strip loop before a coiling machine by rotating a coiling shaft through an intermediate shaft while reciprocating a sliding base in the shaft direction of the coiling shaft. CONSTITUTION:A coiling shaft 11 having a horizontal shaft body 11a projecting concentrically from one end of an expansion/reduction part 11b having a horizontal axis on which the steel strip A1 is coiled is arranged on the sliding base 22. A spline intermediate shaft 41 is arranged in parallel and at an interval with the coiling shaft 11 on the ground side. It is rotated by a drive motor 1 whose intermediate shaft 41 is arranged on the ground side.
