Abstract: PURPOSE:To heighten working accuracy and to improve assembling workability by preventing the chatter of a boring tool when cutting occurring by reducing the length of a boring bar at the working plane of the inner peripheral part of a center cylindrical part, and taking out a signal line after mounting a status side core on the center cylindrical part. CONSTITUTION:The device consists of a drum part 21 in which a lower side drum 20 is set at a divided state and the center cylindrical part 22, and also, it is formed in such structure that an upper bearing 2 is provided on the drum part 21 which forms no cylindrical part 22, and the shortage of rigidity can be suppressed by reducing the length of the boring bar by reducing the length of inner peripheral part of the cylindrical part 22 on the working plane in an axial direction. Thereby, the chatter of the boring tool can be prevented occurring when cutting. Also, a guide member 29 is mounted on the upper end part of the cylindrical part 22, and a position where the signal line 14 of the status side core 12 is drawn out to the outside is heightened, and the core 12 is mounted in the inside of the cylindrical part 22, then, the signal line 14 can be drawn out to the outside via the guide member 29, which prevents the signal line 14 from being damaged.

Title: Paper feeding device
Inventor: HIGUCHI TOMOHISA
IPC: B65H23/34
Filed: 1992-02-25
Abstract: PURPOSE:To surely remove curl by giving stable back tension to a paper sheet. CONSTITUTION:When the diameter of a roll paper 10 is large, the roll paper is unwound at a high position, which stabilizes a paper pressing bar 19 of an arm 20 at a comparatively high position. At this time, this causes a large difference in angle between in the direction in which a spring 22 is energized and the direction in which the working point of the spring 22 works, and the energizing force of the spring is not efficiently transferred. Therefore, the lower direction pressing force given to the paper pressing bar 19 of the arm 20 is small. On the contrary, in the case of a small diameter, the roll paper is unwound at a low position, which stabilizes the paper pressing bar at a comparatively low position. At this time, the difference in angle is comparatively small, efficiently transferring the energizing force of the spring to the arm 20. Therefore, the lower direction pressing force given to the paper pressing bar 19 is large. For this reason, with the reduction of the mass of the roll paper, the friction caused by a friction member becomes large, as a result, stable back tension can be obtained.

Abstract: PROBLEM TO BE SOLVED: To accurately polishingly remove a surplus filler filled in the repair part of a metal plate without requiring the skil of a worker. SOLUTION: A polishing hand tool 10 has a main body 14 and a grasp part 16. A polishing member 20 having a polishing work face 12 is attachedly fitted to a support plate 18 fixed to the bottom of the main body 14. A grasp part 16 has the first grasping element 24 attached to the main body 14 so as to be rotatable about an axial line 22 parallel to the polishing work face 12 and the second grasping element 26 formed fixedly on a pair of sides 14b extending in the longitudinal direction of the main body 14. In the case of finish-polishing, a worker lightly grasps the first grasping element 24 with two fingers of his one hand and rectilineally and reciprocatingly slides the polishing work face 12 in a direction nearly perpendicular to the axial line 22 on a polishing object surface with proper pressing force acting on the polishing work face 12.  In this case, since the first grasping element 24 can rotate to the main body 14, the polishing work face 1 slides as it naturally copys the irregularity of the polishing object surface.
