Title: Controlling method for driving wedge type oil hydraulic screw down device
Inventor: SAKAMAKI KOUKICHI
IPC: B21B31/30
Filed: 1981-07-14
Abstract: PURPOSE:To control the driving of a titled device with high responsiveness, fast responsiveness and control accuracy by so constituting said device that a constant frequency signal is superposed on a position control signal and the piston of an oil hydraulic cylinder for driving a wedge is finely oscillated by said signals. CONSTITUTION:Since a constant frequency signal E0 is superposed on an actual position Ef together with a position control signal Ea in the input part of a control system, the deviation signal epsilon inputted to a servo amplifier 11 includes the constant frequency signal component. Then the spool of a servocontrol valve 9 moves to the position corresponding to the level of the signal Ea and moves back and forth finely at 1/fL frequencies in said position. Therefore the piston 7a of an oil hydraulic cylinder 7 is changed over and controlled under oscillation and a wedge 5 oscillates finely in horizontal directions at all times. Thus the friction and sticking phenomena on the surface of the wedge 5 are eliminated, and the device responds surely and quickly to any minute output change of the valve 9.

Title: Permanent magnet for three-phase a.c. synchronous motor
Inventor: KAWADA SHIGEKI
IPC: H02K1/27
Filed: 1987-05-06
Abstract: PURPOSE:To reduce cogging torque and torque ripple, by employing an octagonal permanent magnet and setting a specific ratio between the side and the length thereof. CONSTITUTION:An octagonal permanent magnet 12 is symmetrical with respect to an axis 18 where the profile thereof comprises two sides 20 which are parallel with the axis 18, two other sides 22 which are perpendicular to the axis 18 and located at same distance from respective sides 20 and four other sides having same length. Ratios between the length W3 of the side 20 and the distance W2 between two other sides 22, and between the length H3 of the side 22 and the distance H2 between the sides 20 are varied such that W3/W2 is 1/25-1/20 while H3/H2 is 9/20-10/20 for obtaining counter-electromotive force having substantially sinusoidal waveform. Consequently, counter-electromotive force has substantially sinusoidal waveform and torque ripple caused through mutual function with three-phase sinusoidal current is reduced, while furthermore cogging torque is reduced because of approximately hexagonal permanent magnet having short sides 20 with a length W3.

Title: Scanning optical device
Inventor: SHIRAI MASAHIRO
IPC: G03B27/32
Filed: 1986-05-15
Abstract: PURPOSE:To miniaturize a scanning optical device, by making the scanning track of a reflecting mirror straight and, at the same time, controlling the rotational angle of the mirror in accordance with the displaced quantity of the mirror. CONSTITUTION:When a motor 12 is driven, a gear 14 moves in the scanning direction while rotating on the straight line of a scanning track XX' or on a track 11 provided in parallel with the line XX' and a reflecting mirror 6 moves along a straight track. As the mirror 6 moves, a worm wheel 21 coupled with the reflecting mirror 6 rotates in accordance with the displaced quantity of the mirror 6 and the inclination of the reflecting surface of the mirror 6 changes. Since the rotational angle of the reflecting mirror 6 is very small as compared with the moving distance of the mirror 6 in the scanning direction, the number of teeth of the gear 14 is made smaller than that of another gear 15 so that the rotation of the gear can be transmitted to the worm wheel after reduction in speed and the center point O of the reflecting surface of the mirror 6 can always be positioned on the straight scanning track XX' during scan. When the gear ratio between the gears 14 and 15 is changed, appropriate displacement of the reflecting mirror in rotational angle can be obtained in accordance with the displaced quantity of the mirror in the scanning direction.
