Title: Steam governing valve
Inventor: YAMANAKA KAZUNORI
IPC: F16K1/42
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To smooth flow downstream of a valve element so as to prevent noise caused by the collision of jet and noise caused by the generation of a turbulent vortex by providing the bottom face part of the valve element with a flat face, and providing a circumferential groove of approximately angle shape or semicircular cross section near the outer periphery of the flat face. SOLUTION: A bottom face part of a valve element 1 of a steam governing valve is provided with a flat face 7, and a circumferential groove 9 is provided near the outer periphery of the flat face 7. In the bottom face part of the valve element 1, the radius of curvature R1 of the valve element 1 and the radius of curvature R2 of a valve seat 4 are set to be R1=R2, and the flat face 7 is formed in such a position that the distance h1 from a contact point between the valve element 1 and valve seat 4 is 0.05<h1 /d<0.1 to a valve nominal diameter (d). Steam flow around the valve therefore flows smoothly along the valve seat 4, and turbulence of steam flow caused by the collision of jet downstream of the valve is prevented.  The groove part 9 is provided in such a way as to slow down the flow from the center part of the valve element 1 before joining main flow, so as to suppress the flow velocity of contraflow of circulating flow and to reduce the turbulence of the flow along the valve seat 4.

Abstract: PURPOSE:To improve the cost performance of a communication controller by decentralizing cuing buffers on, so to speak, each character composition circuit. CONSTITUTION:Character composition circuits 3-0 and 3-n set character information, composed by assembly buffers 9-0 and 9-n, on character buffers 10-0 and 10-n; and scanning circuit 4 scans on character composition circuits 3-0 and 3-n and character information on character buffers 10-0 and 10-n is transferred to character process circuit 5 only when transfer control circuit 6 is free. When transfer control circuit 6 is busy, on the other hand, scanning circuit 4 advances its operation to a scan on the next character composition circuit without sending back a character information acceptance signal to the previous character composition circuit.

Filed: 1984-05-23
Abstract: PURPOSE:To simplify a circuit and set more independent signals and more internal states by judging states of signals which show an internal transition state and an external condition by a programmed ROM, and outputting a necessary sequence signal.

Title: Classifying method of magnetic material
Inventor: EMA SHIYUNICHI
IPC: B03C1/00
Filed: 1984-05-23
Abstract: PURPOSE:To perform the classification for magnetic particles of a short time in the classifying method of magnetic material by applying high gradient magnetic field which has attraction force proportional to the diameter of particle for the magnetic particle group having large and small particle sizes and separating the coarse particle group and the fine particle group by means of the difference in the attraction force. CONSTITUTION:High gradient magnetic field causing the attraction force proportional to the diameter of particle is applied to the particle group of magnetic material incorporated with large and small particle sizes within the range of the order of several mmu. By this method, the difference of the attraction force is caused and thereby the coarse particles applied with stronger attraction force can be recovered as magnetized material and the classification in accordance with the difference in particle size can be performed. In this case, the limiting point of the classification is freely selected by regulating the magnitude of magnetic field of outer part. Also, in the above-mentioned classification, the classifying precision can be improved by performing not only one stage but also plural stages.

Filed: 1991-02-12
Abstract: PURPOSE:To improve propulsion performance and to save energy by arranging a drift angle so that the central line of a rudder when the steering angle of a birudder is extended straight along the direction of an oblique flow toward the rear of the propeller of a stern. CONSTITUTION:Rudders 5 and 6 are arranged aft of the propellers 3 and 4 located in positions separated from a central line 2 of a ship hull toward the starboard and the port side and to a stern. The rudder is arranged such that the steering angle of the rudder 5 is 0 degree in a state that an angle equal to an angle alpha of a straight line 10 extending in parallel to the central line 2 of the ship hull and through the center of the steering line of the rudder 5 with an arrow mark 9 indicating a propeller slip stream (oblique flow), i.e., a drift angle, is provided. Thereby, neither lift nor induced drag is generated as in a case wherein the rudder is arranged in parallel to the central line 2 of the ship hull, and a force exerted on the rudder 5 is only an originally generating friction drag D2 of a rudder surface. A ship advancing direction component -F1 of a current force is -F1= D2COSalpha, and resistance of the rudder 5 is reduced to a value sharply lower than that when the rudder is arranged in parallel. Since the rudder 6 is also arranged symmetrical to the central line 2 of the ships'shull, it is similar to the rudder 5.
