Title: Production of linear polyamide oligomer
Inventor: YUASA HIROSHI
IPC: C08G69/46
Filed: 1983-06-03
Abstract: PURPOSE:To produce a linear polyamide oligomer on an industrial scale without resort to a step of grinding, by dropping a linear polyamide melt into forcibly agitated water. CONSTITUTION:A melt of a linear polyamide oligomer of an average degree of polymerization of 3-30 is dropped into forcibly agitated water. Examples of the linear polyamide oligomers used include those of polycapramide, polyhexamethyleneadipamide, and polyhexamethylenedodecanamide, among which the polycapramide oligomer can be used desirably. The average degree of polymerization of an oligomer can be adjusted by suitably adjusting the amount of a chain terminator used, a polymerization pressure, or the like. As soon as the melt is dropped into the forcibly agitated water, it is dispersed in the water to form small lumps, which are gradually converted into patticles by swelling and rupturing.

Abstract: PURPOSE:To promote the cooling of a lower bearing and to improve the cooling performance of the end part of a motor coil by placing the lower end part of a frame and the upper end face of the end ring of the rotor of the motor in a vertically opposed position. CONSTITUTION:The longitudinal length of the lower end part 14f of a main shaft engaged with a lower bearing part 33 supporting the main shaft 14 is protruded by the dimension of the height of the end ring 3e of the protruding part of the rotor 3b of a motor to vertically oppose the lower end part 11f of a frame to the upper end face of the end ring of the rotor part 3b of the motor. Thereby, cooling medium gas easily goes to the external periphery of the lower end part 11f of the frame. A completely wide space is maintained between the external periphery part of the lower end of the frame and the internal periphery face of the coil end part 3e of the motor, thereby generating a circumferential flow along the external periphery of the coil end part 3e and a circumferential flow along the internal periphery part of the coil end.
