Title: Driving device for dc brushless motor
Inventor: WATANABE YUUJIROU
IPC: H02P6/06
Filed: 1990-03-30
Abstract: PURPOSE:To maximize an output torque and improve the power factor of a motor by selecting a desired pair of rotor position signals from a plurality of pairs of selectable rotor position signals. CONSTITUTION:A selecting circuit 30 selects rotor position signals A-C by manual selection from 5 sets of magnetic pole detecting elements 19a-21a, 19b-21b, 10c-21c, 10d-21d, 19e-21e, arranged in advanced phases by predetermined angles, based on the output of a pair of magnetic pole detecting elements suitable for a present rotating speed. A motor drive signal generating circuit 40 synthesizes a motor driving signal based on the rotor position signals A-C. A power amplifying circuit 50 impresses the stator voltages U, V, W of 3-phase, which are formed based on the motor driving signal, on the stator coils 11a-11c of the motor. Accordingly, the delay of phase of a stator current can be compensated when magnetic pole detecting elements of respective sets, which are suitable for the rotating speed of the motor, are selected whereby the torque of the motor can be maximized and the ineffective current component of the motor can be reduced at all times.

Title: Connecting method for cross-linked polyethylene tube, and its structure
Inventor: OGUCHI TAKASHI
IPC: B29L23/00
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To improve the connection strength, by mixing peroxide which has cross-linked reactive property to polyethylene by heat, so that fusion-welding is performed using friction heat which is generated by inserting a cross-linking polyethylene tube into another tube acceptor of cross-linked polyethylene and by rotating one of them. SOLUTION: When a cross-linked polyethylene tube 2 is connected to a tube coupling 1, by rotating the tube coupling 1 around the shaft and inserting one end of the cross-linked polyethylene tube 2 fixed not to rotate into the tube acceptor of the coupling 1, temperature of a connection part 3 reaches about 250 deg.C. When the tube coupling is rotated for more 25 sec with maintaining this temperature, the connection part 3 between the tube coupling 1 and the tube 2 melts and they are fusion-welded. In this case, to provide a cross-linked polyethylene tube and a tube acceptor with high heat resistance, peroxide which causes polyethylene to perform cross-linking reaction by heat during molding is previously added to the molding materials. For example, dicumylperoxide is used as such peroxide.
