Title: Particulate polyarylate and its production
Inventor: KISHIMOTO SOICHIRO
IPC: C08G63/79
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To produce a particulate polyarylate free from active terminals, having a low content of a fine powder, a high bulk density and good handleability by feeding a methylene chloride solution of a polyarylate into an aqueous polyarylate slurry. SOLUTION: A methylene chloride solution of a polyarylate is fed from a feed pipe 3 into an aqueous polyarylate slurry being heated at 400-100 deg.C at atmospheric pressure in a granulation tank 1 and being recirculated and is mixed with the slurry under agitation with an agitator 2. The mixed polyarylate aqueous slurry is withdrawn from a slurry outlet pipe 6 and introduced into a recirculation line while the evaporated methylene chloride is being removed from a distillate pipe 5. The coagulated polyarylate is dispersed by means of an agitator 8 in the line, part of the slurry is withdrawn from a withdrawal pipe 9 as a product slurry, and the remainder is recirculated into the tank 1.  The product slurry is filtered and dried to obtain a particulate polyarylate having a mean particle diameter of 500μm or above, a content of particles of particle diameters of 250μm or below of 5wt.% or below and a bulk density of 0.15 or above.

Title: Heat exchanger
Inventor: YAMAMOTO KATSUHIKO
IPC: F24H1/12
Filed: 1989-11-15
Abstract: PURPOSE:To contrive uniform heating of a refrigerant and the improvement of thermal efficiency by providing the heat exchanger with a refrigerant passage member forming many passage in a vertical direction, a heat transfer partition member adhering to one side thereof and heat transfer fins fixed thereon while allowing the thickness at the side of the heat transfer fins of a pass partition of the refrigerant passage member to be thicker than that at the opposite side. CONSTITUTION:A high temperature gas of a furnace 10 is passed between heat transfer fins 22A, 22B of a high temperature gas passage 12, being exhausted from an exhaust pipe 14. A liquid refrigerant of an inlet header 17 is branched into many vertical passage 16 from the lower part of a refrigerant passage member 15, being heated by the heat transfer fins 22A, 22B to become a vapor-liquid two-phase. Produced bubbles climb in the passage 16 and a combustion gas transfers heat to a refrigerant in a high temperature gas passage 12 after it is allowed to flow out from a combustion gas outlet 12. In addition, the whole of a heat transfer partition 11 efficiently absorbs the heat by the use of a heating fluid allowed to flow in the high temperature gas passage 12, heating the refrigerant of a vapor-liquid two-phase state in the passage 16. Furthermore, the heat is smoothly transferred from a wall 15a to another wall 15b by allowing the thickness of a partition 15c of the refrigerant passage member 15 to be thicker than that of the side the heat transfer fins 22A, 22B and the refrigerant passage member 15 becomes uniform temperature, heating the refrigerant efficiently.

IPC: F02B37/24
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To reduce resistance force acting on a rotational ring and to prevent abrasion and creep deformation of a contact surface between a link plate and a notch, by placing a rotational ring provided with a notch engaging with a link plate around its rotation shaft, and by providing three projections on the outer surface of the rotational ring. SOLUTION: A link plate 3 for giving torque is mounted to a rotation shaft 2 of a movable nozzle vane 1, a rotational ring 4 provided with a notch engaging with this link plate 3 is placed so as to cover the rotation shaft 2, and projections are formed at three positions on the outer peripheral surface of the rotational ring 4. When counterclockwise force orthogonal to the projections is acted on the rotational ring 4, the rotational ring 4 moves in the load direction, the projections collide against the inner peripheral surface 7 of the casing, moment in the load direction acts to the rotational ring 4. But, when angle of each projection is larger than 90 deg., only force formed by subtracting inertia force from frictional force on a contact surface acts to the ring. Thus, abrasion and creep deformation of a contact surface between the link plate 3 and the notch are restrained.
