Title: Drive controller for servomotor
Inventor: ONO SHUNICHI
IPC: H02P29/00
Filed: 1991-12-20
Abstract: PURPOSE:To shorten a rise time by providing a signal changeover means for each region using a desired value as an input signal and the current value of a motor rotational speed as a feedback signal after a servomotor reaches a target constant-speed rotary region. CONSTITUTION:When reaching a target constant-speed rotary region of a current value S1 is discriminated by constant-speed rotary-region reaching discriminating means 11, 12, a controlled variable Sc to a driver circuit 20 is changed over selectively from a fixed quantity Scst to a variable value. When a start command is written to an output port 15, the signal changeover means for each region 11, 12 change over a fixed quantity Scst so as to be input to the driver circuit 20 because the number of revolution of a DC servomotor 1 is zero, and the CPU 11 outputs a fixed quantity Scst to the driver circuit 20 as the controlled variable Sc. Accordingly, the DC servomotor 1 is acceleration-controlled, a feedback signal Sf is interrupted until the servomotor reaches a target constant-speed rotation from a rotational drive start point, and a fixed quantity Scst is added as the controlled variable Sc in place of a desired value Sg, thus allowing reaching the target constant-speed rotary region at an early time.

Title: Fixed type constant velocity universal joint
Inventor: KADOTA TETSUO
IPC: F16D3/2245
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of rotation backlash. SOLUTION: A twisted spring 5 contained in the recessed part 2d of an inner ring 2 has one end 5a engaged with the engaging groove 4b of a holder 4 and the other end 5b engaged with the wall surface of a recessed part 2d, and this way causes constantly resiliently press of a holder 4 against the inner ring 2. Thereby, a ball 3 contained in the pocket 4a of the holder 4 is constantly resiliently pressed against the wedge side (the opening side) of a ball track by the holder 4. This constitution eliminates a peripheral clearance between guide grooves 1b and 2b and the ball 3 and prevents the occurrence of the rotation backlash of a joint.
