IPC: F22B35/00
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To prevent significant fluctuation in the temperature of a main steam when altering the opening of a reheater gas damper by a precedence command for the reheater gas damper during the increasing or decreasing of the output command for a dynamometer. SOLUTION: This main steam temperature control method controls a spray flow rate to be supplied into a main steam based on a spray flow rate command 35 obtained from an output command 27 for a dynamometer. The spray flow rate command 35 is corrected by a spray flow rate precedence correction signal 55 obtained based on a reheater gas damper precedence command 54 to increase the spray flow rate during the decreasing of the opening of a reheater gas damper or decrease it during the increasing of the opening of the reheater gas damper.

Abstract: PURPOSE:To dispense with accurate working, perfectly prevent leakage of fluid containing pebbles and the like, and improve transport efficiency, by forcing respective belts and the inner wall of a pump casing to make contact with each other so as to generate no slip between them, when a pair of rotors are rotated. CONSTITUTION:Rotors P, Q intersect at right angles with each other, and the rotor P comes in contact with the belt 14 of the rotor Q in the condition of pushing it. Next, the respective rotors P, Q are rotated in the arrow mark direction to be in nearly parallel condition, but even in this case, the belts 14 of both rotors P, Q are kept in mutual contact condition. Further, both rotors P, Q are advanced in their rotation, and the rotor Q comes in contact with the belt 14 of the rotor P in the condition of pushing it. Hereafter rotating action of the rotors P, Q is further continued. Consequently, even though pebbles and the like contained in the fluid are pinched between the rotors P, Q and a casing 3 or between both rotors, are caught by compression and bending performance of the belt 14, transport of the fluid can be continued without being obstructed by individuals in the fluid.

Title: Origin return system
Inventor: KITANI NOBUYUKI
IPC: G05B19/18
Filed: 1989-08-22
Abstract: PURPOSE:To make a correct return to the origin even if various conditions change at the time of the origin return by selecting a grid in constant relation with an abutting position. CONSTITUTION:An origin control means 16 supplies a torque limit signal to a servo amplifier 15 to control the output torque of a servo motor 21. Then a table 24 is made to travel at a constant speed and when an abutting member 25 abuts on a fixed part 26, the table 24 can not moves, so that the error quan tity of an error register 13 increases abruptly. When the error quantity exceeds a constant value, the abutting of the abutting member 25 of th table 24 on the fixed member 26 is sensed and distribution pulses CPX are stopped. Then an origin control means 16 catches a grid outputted by a reference counter 11. This caught grid is different according to an origin return speed, so a grid calculating means 14 finds the grid in the constant relation with the abutting position from the grid which is caught for the 1st time and the error quantity of an error register 13. For example, the point which is closest to the abutting position is regarded as a grid for origin returning.

Title: Production of plating film
Inventor: KAWAGUCHI NAOYA
IPC: H05K1/09
Filed: 1990-08-17
Abstract: PURPOSE:To reduce the time of plating for Cu electroplating on an amphoteric metal thin plate by first forming a Cu plating thin film of specified thickness in a copper pyrophosphate plating liquid and then providing a thick Cu plating film thereon in a copper sulfate plating liquid. CONSTITUTION:First, a Cu plating thin film is formed to 0.3-10mu thickness on an amphoteric metal thin plate as a cathode with using a copper pyrophosphate plating liquid (containing no glossing agent). Then as using the plate as a cathode, a thick Cu plating film is formed thereon with using a copper sulfate plating liquid. The first thin plating film is formed preferably to 0.3mu or more thickness to uniformly cover the whole surface of the metal and to <=10mu thickness because it takes long time to make a too thick film. By this method, the amphoteric metal does not dissolve in the plating liquids so that the copper plating film of enough adhesion strength can be obtained in a short time significantly reduced compared to the conventional plating method using a copper pyrophosphate plating liquid.
