Title: Pipe and heat exchanger
Inventor: HIKIFUYU SHOJI
IPC: F28F1/42
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To enhance heat transfer characteristics and to eliminate standing of liquid by spirally corrugating a circular tube except a flat stripe part formed in the circular tube along the tube axis and making the corrugation deeper gradually from the flat part such that it is deepest at a part symmetric to the flat part. SOLUTION: When a circular tube 1 is corrugated spirally, it is formed while shifting the center O of spiral (axis) by dimension ε from the tube axis L in the transverse section to form a flat part 2 extending linearly along the tube axis L in the circular tube 1. More specifically, inside diameter of corrugation (root) of the circular tube 1 is shifted downward by a slight dimension εfrom the tube axis L and a non-corrugated linear stripe flat part 2 is formed along the tube axis L. The corrugation becomes shallower (height dimension of corrugation becomes lower) gradually and obliquely from the upper part toward the bottom part of the tube through the opposite sides thereof and no corrugation is formed (height dimension of corrugation becomes zero) at the flat part 2.

Inventor: IMAI KOJI
IPC: H02K17/26
Filed: 1995-04-14
Abstract: PURPOSE: To provide an induction motor, which has the small torque pulsation and can generate the high torque. CONSTITUTION: A conducting rod 54 is attached to a tubular rotor 34. Therefore, when a stator 22 is excited and rotating magnetic field is generated, the induction current is induced by the conducting rod 54, and the torque is generated. Thus, the tubular rotor 34 is rotated. When the rotating speed of the tubular rotor 34 is increased, the induced current with the conducting rod 54 is decreased, and the torque is reduced. The tubular rotor 34 is rotated in synchronization with the rotating magnetic field by the magnetic force of a permanent magnet 36 attached to the tubular rotor 34. The magnetic flux generated in the stator 22 is directed to the facing permanent magnet 36. Therefore, the magnetic flux crosses in the direction of the diameter with respect to the rotor 26, and the torque generated in the rotor 26 becomes large.
