Title: Induction motor and adjustment method for power factor
Inventor: IMAI KOJI
IPC: H02P23/07
Filed: 1995-03-24
Abstract: PURPOSE: To generate high torque and make it possible to adjust power factor, by using a piece of permanent magnet movable in an axial direction of the magnet, in which the area of a magnet facing a pole of a rotating field of a stator is changeable. CONSTITUTION: A magnetic line of force 90 from a winding 23 extends toward an opposite permanent magnet 36, while a magnetic line of force 90 of the permanent magnet 36 extends opposite toward the winding 23. Then, the magnetic flux extends in a radial direction of a rotor 26. As a rotating field is rotated, velocity electromotive force at a secondary conductor (H) moving relatively to magnetic flux (B) in a direction of an arrow (C) becomes equal to a product of an effective magnetic flux factor and the velocity in a Fleming's ring-hand low. The interactive force between a current and the magnetic flux at the secondary conductor (H) is generated vertically to the magnetic flux (B) in a radial direction and causes the rotor 26 to rotate. As a result, the force generated at the secondary conductor (H) are all effective as torque of the rotor 26.

Title: Setting method of space between end faces of optical fibers in method for welding and connecting optical fibers
Inventor: UEMATSU YUUJI
IPC: G02B6/255
Filed: 1984-05-09
Abstract: PURPOSE:To enable exact setting of a space between end faces 0 in the stage of welding and connecting by making at least once the relative movement of the end faces of optical fibers in a counter-butting direction and an axially offcentering direction in optional order. CONSTITUTION:The end faces 2A, 2B of the optical fibers are axially centered and the max. photodetection power P1 is obtd. The end 2A is moved toward the end 2B and the power attains the peak at the point P2 when the space between the end faces 3A and 3B attains zero. The end 2A, when moved further, is overpushed as shown in figure (c) and the level of the photodetection power decreases to the point P3. The end 2A is then moved in the counter-butting direction and the movement is stopped when the point P4=P2 is attained. The one end 3B is slightly moved in the axially offcentering direction and if the photodetection power does not change any more, the failure in maintaining exactly the zero space between the end faces is indicated. On the other hand, if the accuracy of the space between end faces = 0 is high, the level of the photodetection power decreases down to the point P5 and therefore the state of the exact space between the end faces = 0 is attained by moving the end 2A until the power P5 is generated by the axial offcentering operation after detection of the power P4.
