Title: Slide valve of screw-type hydraulic machine
Inventor: KISHI TAKAYUKI
IPC: F04C28/12
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction in the efficiency due to overcompression in a slide valve which controls the amount of return or capacity of the fluid to be returned to the suction side, by providing, at the slide valve, a groove crossing a cutout part of either of male or female rotor out of the cutout parts for discharge control of the slide valve discharge port. SOLUTION: When a control oil pressure is applied to an unloader piston 5, an opening area of a return passage from a discharge side to a suction side is determined by the movement of a slide valve 6. In other words, when the slide valve 6 moves to the low-load side, a discharge port 70 is moved to the discharge side, and the volume ratio inside a slide valve discharge port is reduced. When the slide valve is further moved to the low-load side, the effect caused by the movement of the discharge port 70 toward the discharge side is increased, and the discharge timing is delayed, so that the inside volume ratio is gradually increased.  Thus, by forming a groove 63 so as to cross a cutout 62 out of the respective cutout parts 61, 62 both on the male rotor side and female rotor side of the slide valve 6 for controlling the discharge quantity, the inside volume ratio at the time of partical load can be set to a lower value.

Title: Drive method for stepping motor
Inventor: OGASAWARA MASASHI
IPC: H02P8/22
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To suppress vibration during micro-step driving, without complicating a control circuit, by forming the exciting current, supplied to the phases by micro-step driving, into triangular-wave current. SOLUTION: The waveform of reference voltage, supplied to a motor driver by micro-step driving, is formed into that of triangular waves that linearly increases or decreases. This enables forming the waveform of the exciting current supplied to a first coil (a) and a second coil (b) into that of triangular waves that linearly increases or decreases as well. As a result, the sum of the exciting currents passed through the first coil (a) and second coil (b) becomes constant, and no ripple is produced due to superposing currents. This enables suppressing more effectively the vibration of the stepping motor, without producing any torque ripple.
