Title: Printing hammer
Inventor: MURAKAMI KOHEI
IPC: B41J9/38
Filed: 1989-08-24
Abstract: PURPOSE:To obtain a longlife hammer almost free from rebound by providing a metal weight weighing properly and a support member of viscoelastic material for supporting the weight, as a plunger-type stopper. CONSTITUTION:A stopper part 8 screwed to a case 1 consists of a weight 9 and a weight support 10 insetted into each other in one piece. The weight support 10 is formed with a highly viscoelastic material, and the metal weight 9 weighs properly. Furthermore, the weight 9 is coated 11 to protect a metal plunger 6. If power is applied to a coil 2 for a fixed time, the plunger 6 overcomes a return spring 7 to move to the center of a magnetic circuit, and further moves in (a) direction by inertia to perform printing. After that, the plunger 6 returns to its home position by printing reaction and spring 7 force to collide with the stopper part 8. At this time, the kinematic energy of the plunger 6 turns to the motion of the weight 9 and this motion is absorbed by the weight support 10 of the support member for the weight 9.

Title: Automatic string winding device
Inventor: ISHIGURO TOSHIYUKI
IPC: B65H65/00
Filed: 1982-12-16
Abstract: PURPOSE:To make it possible to start to wind a string round a reel regardless of the dimentional accuracy of the reel by providing a spring forced string holder on a reel holding turning part and constructing the captioned device in such a way as catching and releasing the initial winding end of the string with said holder at respective green positions. CONSTITUTION:One of string ends already cut off is delivered out at the winding final end of a reel 1 while left as it is or temporarily fixed to the reel 1 with an arbitrary method. The other end of the string caught by a clamp 25 is turned downward together with the clamp 25 by the operation of a fluid pressure cylinder 27 when a transverser 3 reaches the stroke end of a holding head 12 side and stops or just before that situation and put into a string holder 15 where a string W end part opens and waits for the insertion of the string. Thus, string end delivery is completed by pulling back an operating tool 17 which has been pushed out such that the string holder 15 holds the string W end and allowing the clamp 25 to be opened by releasing the force of a built-in cylinder. Accordingly, it is possible to readily restart string winding by returning a cutter blade to the initial position thereof, putting back a sheave 19 to its waiting position, and inserting a new reel 1 between the holding heads 12, 13.
