Title: Method and apparatus for stopping film
Inventor: YANAGAWA HITOSHI
IPC: B65H26/00
Filed: 1981-02-03
Abstract: PURPOSE:To enable to stop a film accurately by a method wherein after a pair of mark detectors provided at positions spaced from each other by a distance equal to half of the length of a mark provided on the film have simultaneously detected the mark, while the feed of the film is stopped upon feeding the film by a length equal to 1/4 of the length of the mark. CONSTITUTION:The mark 16 having a density different from that of the surroundings is provided on one side of each frame 15 of the film F, and one pair of mark detectors 12, 13 are provided at the positions spaced from each other by a distance approximately equal to one half of the length l of the mark 16 as measured in the feed direction of the film. When both the detectors 12, 13 feed out mark detection signals under the condition where AND gates 21, 22 are fed with control signals a, the gate 22 is opened and the number of pulses is counted by an addition counter 25. When the film is fed by a distance equal to one half of the spacing between the detectors 12, 13, the count value of the counter 25 and a quotient value in a dividing circuit 26 become equal to each other, and a signal b for stopping the film is outputted from a comparison circuit 27.

Title: Hammer drill
Inventor: SAKAMOTO YOSHIHIRO
IPC: B23B45/16
Filed: 1988-01-26
Abstract: PURPOSE:To suppress the generation of noise by making a drill bit movable in the axial direction in a spindle, providing a striker between a striking body and the drill bit axially movably in the spindle, and linking the striker to the engaging/disengaging means of a clutch. CONSTITUTION:When the tip of a drill bit 8 is not applied on a machining face, a striker 33 is in an advanced position while a clutch 6 is in a disengaged condition being energized by a clutch shaft 60 by means of a spring. Hence, as a switch handle 14 is operated, the rotation of a motor 2 is transmitted to the drill bit 8 from an intermediate shaft 23 via a spindle 3. However, since a motion converting member 5 is being disconnected, the reciprocation of a piston 4 does not take place and only the drill bit 8 carries out rotation. In this condition, as the tip of the drill bit 8 is pressed against the machining face, the striker 33 is retracted engaging the clutch 6. The reciprocation of the piston 4 is followed by a striking body 41, which is transmitted to the bit 8 through the striker 33.
