Title: Method of balancing radial directional force on gear pump or gear of motor and planet gear pump manufactured by said method
Inventor: ZHENG YUE
IPC: F04C2/14
Filed: 1991-02-21
Abstract: PURPOSE: To balance radial forces on gears of a gear pump or motor and planet gear pump so as to solve a problem relating to a bearing and to raise overall efficiency of the gear pump. CONSTITUTION: Radial seal of four engaged gears 1-4 is realized by radial blocks 5-7. Both ends of each block are mounted liquid-tightly with respect to the tooth tip. The dotted areas formed in correspondence with the rotating direction of the gears are high-pressure areas of liquid pressure. Both high and low pressure fluids flow in and out through axial openings in a side plate, conducting sealing in radial direction and forming three equal external gear pump High-pressure areas are equally spaced around the axes of the gears for gears 1, 3 to neutralize actually acting liquid pressures. The gears 1, 4 are still applied by the action of one-way liquid pressure. The more the number of gears engaged in series, the lower is the total average radial pressure.

Inventor: HANEDA HIROSHI
IPC: B21C37/29
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To easily form a cylindrical burring wall on the side of the inner peripheral surface of a metal tube by forming a through hole by eliminating a part of the outer peripheral wall of the metal tube and pressing the through hole part from the outward with a punch whose diameter is larger than the diameter of the through hole. SOLUTION: An elliptic prepared hole is bored in a part of the outer peripheral wall of the metal tube 1 by a press cutting method in which a circular-arcuate blade is straightly moved or a method by which cutting or grinding is executed by revolving a grindstone. Next, the prepared hole part of the metal tube 1 formed on the outer peripheral wall is pressed inward in the radial direction by a pressing method with the punch 5 whose diameter is larger than that of the prepared hole formed on the outer peripheral wall of the metal tube 1. In this way, the cylindrical burring wall 4 which is extended in the radial direction is formed on the side of the inner peripheral surface of the metal tube 1.  Relating to the through hole 3 made in the above-mentioned manner, the edge 6 is formed without generating a shear droop in an opening part on the side of the outer peripheral surface of the tube, preferably longer than the thickness of the metal tube 1 with the cylindrical burring wall 4 which is extended in the radial direction of the metal tube 1 and in the opening part on the outer peripheral surface of the tube.

IPC: B08B1/04
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a substrate cleaning time which can effectively perform cleaning treatment with little downtime. SOLUTION: After a worker teaches the starting position, ending position, etc., of bush scanning to a substrate cleaning device at the time of starting the device (step S1), the worker throws each cassette in a cassette stage 11 (step S2) and sets a cleaning treatment recipe containing different bush rotating speeds, cleaner scanning rates, cleaner scanning widths, etc., in accordance with the objective cassettes (step S3). Thereafter, cleaning treatment is sequentially and automatically performed on the substrates housed in the cassettes in accordance with the corresponding recipe at every cassette. Since it is not required to set the cleaner scanning speed at every cassette, little downtime occurs and effective cleaning treatment can be performed.
