Patent JP-H0326891-A (JP)
Title: Screw type fluid machinery and rotor thereof
Inventor: MORI HIDETOMO
IPC: F04C18/16
Filed: 1989-06-21
Abstract: PURPOSE:To improve performance by setting the difference between the advance surface and retreat surface of the rand of the tooth of a rotor nearly equal to the value which is obtained by dividing the difference of the interference quantity of the teeth at the both edges of the rotor by the number of turns. CONSTITUTION:Since a difference is generated between the lead of the advance surface 23 of the rand part 22 of tooth and the lead of the retreat surface 24, and the lead of the advance surface 23 is large, the groove width reduces in rectilinear form in the longitudinal direction of a shaft from the side having the larger tooth length to the less tooth length side. Therefore, if the rotors 1 and 2 having different distortion direction are meshed each other, the gap on the side having the larger tooth length is large, and the gap on the side having the less tooth length is small, and the gap varies rectilinearly. Since the variation of the gap and the variation of the interference quantity between the rotors 1 and 2 are nearly equal, the variation of the interference quantity can be absorbed. Therefore, even if the interference quantity of the teeth varies in the longitudinal directions of the rotors 1 and 2, the necessary gap can be applied onto the side surfaces of the teeth of the rotors 1 and 2, and the performance can be improved.

Abstract: PURPOSE:To eliminate any control dragging as well as to improve the extent of acceleratability by installing a control ending means, ending the engine power control at a time when car acceleration has exceeded the specified upper limit acceleration, in a device which controls the engine power at a slip occurring. CONSTITUTION:A slip controlling means 70 controls the output of an engine so as to make a slip value turn to a desired slip value corresponding to the friction factor of a road surface at a time when each slip value of driving wheels against the road surface has exceeded the specified threshold value, and this output control takes place by controlling the opening of a sub throttle valve 45 at the upstream side of a main throttle valve 43 with an actuator, by way of example. In this case, there is provided a wheel speed sensor 66 for detecting each wheel speed of driven wheels, and car acceleration is detected from a variation in driven wheel speeds by an acceleration detecting means 77. When the car acceleration has exceeded the specified upper limit acceleration, the above output control is made so as to be ended by a control start-end means 80, and the upper limit acceleration is set so as to be the lower, the higher in car speed.

IPC: F16C17/10
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To be excellent in durability, ideally use for high speed rotation, and easily machine a dynamic pressure generating groove by forming the dynamic pressure generating groove by reactive ion etching on hard membrane. SOLUTION: Hard membrane 7 composed of diamond like carbon(DLC) is coveredly attached on a surface of a round bar-like base material 6 composed of metals including stainless steel and aluminum alloy. After the membrane is formed, a dynamic pressure generation groove 5 is formed by reactive ion etching to oxidize DLC (carbon) followed by gasification and removal. Burr is thereby not generated and machining man-hour for finishing machining becomes unnecessary, resulting in crease in machining cost, and a homogeneous membrane without a crack is strongly and coveredly attached on the base material 6 and prevented from flaking by the crack to maintain a status of low friction and low wear even against frequent start and stop since DLC membrane 7 is coveredly attached on a wide area of a smooth surface of the base material 6 without unevenness before being formed of the groove.
