Title: Plate fin type heat exchanger
Inventor: MUTO TAKASHI
IPC: F28F1/30
Filed: 1993-09-16
Abstract: PURPOSE:To cause forcedly a disturbed flow and activate an irregular disturbed eddy flow movement by a method wherein fins at low temperature fluid side are inclined in respect to a flowing direction of a fan, or they are provided with a roundness. CONSTITUTION:A heat exchanger is constructed such that fins 3 at high temperature fluid side and fins 2 at low temperature fluid side are partitioned and piled up on plates 1. Then, high temperature fluid flows from an upper tank 4 toward a lower tank 5, and in turn the low temperature fluid forcedly generates a flux of disturbed thermal flow under an inclined state or having a radius against the flowing direction of the fan so as to promote a heat transfer with the disturbed thermal fluid. With such an arrangement as above, a heat transfer of a heat exchanger is improved and then a pressure loss of discharged air can be reduced.

Title: Investigating method of rotating speed-dependent oscillation of rotary machine
Inventor: KAMIYOSHI HIROSHI
IPC: G01M99/00
Filed: 1983-12-06
Abstract: PURPOSE:To obtain a more accurate test result by varying the rotating speed of a rotary machine stepwise while holding the load condition of the rotary machine constant, and calculating the attenuation ratio or permissible oscillation coefficient of the rotary machine from oscillation response data of every rotating speed. CONSTITUTION:While the load condition of the rotary machine is held constant, the rotating speed is increased to 1,000, 2,000, 3,000, and 4,000r.p.m. to perform stationary operation for a specific time at every rotating speed, and the oscillation frequency is varied gradually within a target range to measure oscillation response. Data on it are collected and analyzed to calculate the attenuation ratio xsi or permissible oscillation coefficient. Consequently, when the load condition is constant and the rotating speed is varied, the natural oscillation frequency, attenuation ratio, stability tolerance, and dangerous speed of the rotary machine are calculated and a more accurate test result is obtained.

IPC: H01J29/90
Filed: 1984-11-02
Abstract: PURPOSE:To enable to furnish an electron gun with relatively smaller electron ray focusing and deflection aberration depending on a narrower feeder line arrangement, by insulation coating the feeder line except for bendable portions which are smash processed or formed by combining ribbon form conductors. CONSTITUTION:The feeder line 10 is covered with insulation coating 11 and a few parts without coating are formed into bendable parts 10a and 10b by a smashing process, and, the parts 10a and 10b are smashing processed in different directions. The bendability is secured in the direction to the thinner side by the process, so that the whole feeder line 10 is bendable up and down at the part 10a and vertically on the paper at the part 10b. Therefore, the feeder line can be placed in a narrow space by presetting them where other electrodes, exposed feeders, or inside walls of the outer tube will not contact them. In such a way, an electron gun with relatively smaller electron ray focusing and deflection aberration can be furnished.

Title: Three phase fluidized bed reactor
Inventor: KANEKO MASAHITO
IPC: B01J8/22
Filed: 1987-09-17
Abstract: PURPOSE:To enable an efficient separation of liquid and gas out of a three phase fluidized bed reactor by forming the inlet part of a liquid suction pipe, which vertically penetrates the reactor, into an inverted cone on which a cylindrical inlet port is attached and by arranging spiral baffle plates, which are attached to the outside periphery of that cylindrical port, in contact with the inside wall of the reactor. CONSTITUTION:A three phase fluidized bed is formed by introducing a gas and a liquid into the bottom of a solid particle bed in a reactor 1 through a distributor. The liquid, after passing the fluidized bed, is drawn out of a suction pipe 9, which vertically penetrates the bed at the center, and circulated again to the reactor by a pump set inside or outside the apparatus. The inlet part of the suction pipe 9 is formed into an inverted conical connecting part 8 on which a cylindrical inlet port 6 of the suction pipe is attached. More than one baffle plates 7 are attached to the outside periphery of this inlet port 6 and brought into contact with the inside wall of the reactor 1. As a result of these arrangements, it becomes possible to enlarge a steady operation range of the reactor, as a lowering of a delivery performance of the circulation pump is avoided by suppressing a gas to be contained in sucked liquid.
