Title: Ink ribbon spreader
Inventor: MATSUMOTO YOSHIKANE
IPC: B41J17/28
Filed: 1979-08-18
Abstract: PURPOSE: To prevent the ink ribbon from being creased, by spreading the ribbon like an unfolded fan from the longitudinal center of a ribbon spreading rod when the ink ribbon is moving in contact with the groove of the rod.  
     CONSTITUTION: When the ink ribbon 4 is moving in the direction of an arrow (a), the ribbon spreading rod 10a is inclined by motion resistance in a direction to come into contact with a stopper 13a. The ink ribbon moves in contact with the hammer- side spreading surface 15a of the rod 10a when the rod is inclined. At that time, the ink ribbon moves along an oblique groove 16a on the spreading surface 15a. As a result, the ribbon is spread perpendicularly to its moving direction, from the longitudinal center of the ink ribbon. Since a ribbon spreading rod 10b is inclined in the direction to come into contact with a stopper 12b, the ink ribbon 4 is spread by a spreading surface 14b at the side of a winding shaft.

Title: Rotary electric machine
Inventor: HAGINO HIROYUKI
IPC: H02K5/04
Filed: 1979-08-22
Abstract: PURPOSE:To prevent the resonance of equipment, by tapering the inside of a stator frame and the outside of a stator core fitted in the frame, at angles, and by controlling an interference for tight fitting assembly depending on tight fitting pressure. CONSTITUTION:The inside of a stator frame 8 and the outside of a stator core 9 of laminate structure are tapered at angles. The interference for tight fitting the assembly of the frame 8 and the core 9 is increased when the core 9 is moved toward the minor part of the inside diameter 8 of the frame 8. At that time, the natural frequency of the rotary electric machine itself is heightened. The natural frequency is determined by the frame 8, the core 9 and a spring constant k1 between them. When the natural frequency and the vibration frequency are coincident with or approximate to each other, the spring constant k1 can be changed by the interference for the frame 8 and the core 9. The resonance of equipment is thus avoided.
