Title: Shaft coupling and steering column assembly using it
Inventor: TAKANO KAZUYA
IPC: F16D3/58
Filed: 1995-04-14
Abstract: PURPOSE: To prevent the stress concentration of a connection part by arranging cylindrical bodies enclosed by a rubber elastic body connected to either of a driving shaft or a driven shaft concentrically with equal intervals, connecting it by a synthetic resin disk body, and arranging cylindrical projections connected to the other shaft concentrically with equal intervals on the disk body in an alternate manner to the cylindrical bodies. CONSTITUTION: A cylindrical body 1 is connected to a driving shaft, and a cylindrical body 2 is connected to a driven shaft, and two bodies of each kind are generally provided, and correspond to a yoke extending from each shaft, and alternately and concentrically arranged. A rubber elastic body 3 encloses the whole circumference of the cylindrical body 1 to be served for absorbing the vibration during the rotation and for buffering the rapid load, and also reduces the noise. In a synthetic resin disk body 4, the rubber elastic body 3 is arranged at the prescribed position, and the cylindrical body 2 is integrated with the synthetic resin disk body 4. The synthetic resin directly transfer the rotational torque, and the torque is transferred to the driven shaft by the resistance of the synthetic resin against the tensile and compressive forces between the cylindrical bodies 1, 2.  Because no coupling part is present, the disadvantage of entering water or oil is eliminated.

Title: Arc output control method in one-side automatic welding
Inventor: NOMURA HIROICHI
IPC: B23K9/095
Filed: 1978-09-19
Abstract: PURPOSE: To improve arc output detecting accuracy and hold arc piercing power constant by burying photoelectric photo detectors in the specified 6 positions of the light transmittable backing material for one-side automatic welding and controlling welding conditions by the electric signals of these photo detectors.  
     CONSTITUTION: Six photoelectric photo detectors 11 (F'R, F'L, M'R, M'L, B'R, B'L) are buried spacially at the specified distances in the specified positions determined empirically from the point right under a torch 5 respectively in the backing strip 8 in contact with the base metal 1 to be welded by way of a light transmittable backing material 10. The photo detectors 11 receive the transmitting light and emit respectively corresponding signals FR, FL, MR, ML, BR, BL. These addition signals cause the control mechanism not illustrated to move the backing strip 8 to the specified position right under the torch 5. At the same time, the output value at the point right under the arc and the preset correct output value at the point right under the arc are compared based on the addition singals FL+FR and ML+MR and welding conditions are so controlled that the foregoing output differences become 0. Since the arc output is directly detected, the piercing force of the arc is maintained always constant without delay.

Inventor: FUJIMOTO HITOSHI
IPC: G03G15/08
Filed: 1990-04-27
Abstract: PURPOSE:To always form an image under a state where a stable developing action is performed by automatically correcting the detected value of the density of developer adhering to an image carrier within a specified range concerning each developing means attached to a device main body.

IPC: B23Q17/22
Filed: 1990-04-27
Abstract: PURPOSE:To improve machining accuracy by correcting the work origin position based on the measured results of the reference plane of a pallet. CONSTITUTION:When it is detected that a pallet 11 is clamped to a table, a tool 120 is attached to a main spindle by an ATC, a main column is shifted from the origine position (Z=0) in the directions of X-axis, Y-axis, and Z-axis respectively, and stopped when a touch sensor 121 abuts on the reference plane 122. The origin position of a work is corrected for each, carried-in pallet 11 based on the shift amounts SX, SY, SZ through which the tool 120 is shifted in the direction of each axis before it is stopped. After the origin position is corrected, a machining tool 126 is loaded to the main spindle to machine the work-face 43 to be machined. Thus, since the work origin position is corrected even when deformation and positioning errors due to thermal expansion occur, the machining accuracy can be easily improved.
