Title: Load cell
Inventor: KITAGAWA TORU
IPC: G01L1/22
Filed: 1987-04-14
Abstract: PURPOSE:To easily form a load cell which has no characteristic deterioration with high accuracy by fitting both ends of a ceramics plane plate where strain gauges are formed to a fixed body and a load receiving body by shrinkage. CONSTITUTION:The four strain gauges 5 which are bridge-coupled with one another are stuck on the top and reverse surface of the deformation part 4 of a flat plate type strain inducer 1 made of ceramic of Al2O3, etc. One end of this strain inducer 1 is coupled with the coupling groove 7 of the fixed body 6 by shrinkage fitting and the other end is coupled with the coupling groove 11 of the load receiving body 10 by shrinkage fitting to form a load cell main body. Then when a load is placed thereupon on a load receiving hole 12, the load cell deforms as shown in a figure and the resistance values of the strain gauges 5 vary, so that an electric signal corresponding to the load is obtained. Consequently, even when the main body is made of ceramics, the load cell having no deterioration in characteristics is formed with high accuracy at low cost because of the shrinkage fitting.

Title: Coupling
Inventor: SEYA SEIICHI
IPC: F16D3/16
Filed: 1985-04-26
Abstract: PURPOSE:To prevent torque transmission delay and improve precision and durability by providing an oscillating piece having a ball with a through hole and movable in the radial direction on one shaft side and providing a coupling shaft connected to this hole and fixed in the axial direction on the other shaft side. CONSTITUTION:An oscillating piece 9 with its coupling shaft fixed to a flange in the axial direction and coupled with a ball 11 having hole 10 is stored in a flange 7 slidably in the axial direction. Thereby, when the direction of a drive shaft and a driven shaft is eccentric, the oscillating piece 9 repeats the movement in the radial direction via the rolling contact on the inner wall of a long hole groove 8 to transmit the rotation. Therefore, when the shaft is rotated, the ball 11 is rotated, correction is made to solve the one-sided contact between the coupling shaft 4 and hole 10, thus resulting in the face contact on the contact face parallel to the axial direction. Accordingly, torque transmission delay is reduced, and precision and durability can be made excellent.

Patent JP-S5615378-A (JP)
Title: Printing hammer device
Inventor: HO CHIYON RII
IPC: B41J9/127
Filed: 1980-07-10
Abstract: An electro-magnetic print hammer comprises a single magnetic hammer element in which an impact mass is coupled to a pivotted armature by flexible stem. The hammer-stem has (N+1/2) periods of oscillation at its resonant frequency during the free flight time of the hammer mass. A permanent magnet with a strong magnetic force which decays rapidly with distance holds the hammer element fixed upon motion of the armature until the armature torque exceeds the magnet holding force to cause the hammer mass to break loose with a snap action. Stop means prevents armature impacts with the operating pole piece of a stator core. The visco-elasticity of the armature stop matches the rebound characteristics of the print medium when impacted by the hammer mass.
