Title: Winding of rotary electric machine
Inventor: YOSHIMITSU TETSUO
IPC: H02K3/40
Filed: 1985-09-20
Abstract: PURPOSE:To produce no cavity under the low resistance layer by winding the thermal contracting film or tape of low resistance plastic on the outside of the main insulation layer to form a thermal contracting low resistance layer and by impregnating and hardening the insulating resin to the main insulating layer to form the winding. CONSTITUTION:Surrounding a conductor 1 a main insulation layer 2 is formed, on which a thermal contracting insulation layer 3 is formed. Then, around a thermal contracting insulation layer 3 a thermal contracting low resistance layer 6 is formed which is flatwise wound, half superposed or wound abuttedly with the low resistance thermal contracting plastic film or tape formed and shaped with a plastic material of low resistance in itself. It is then inserted into an iron core slot and impregnated integrally. Thus, since the thermal contracting layer and low resistance layer is the same, the low resistance layer is contracted when the impregnated resin is hardened and heated. As a result, no cavity is produced under the low resistance layer.

IPC: B23K9/12
Filed: 1986-09-04
Abstract: PURPOSE:To achieve a higher accuracy of detecting a groove position, by averaging an intensity distribution of reflected lights along the center lines thereof and that along a plurality of lines parallel wit the center lines to detect changes in the intensity distribution of the reflected lights. CONSTITUTION:A spot laser light is projected to a vibration mirror 27 from a laser projector 23B to be incident on a groove 33 of material 25 to be welded slantly from above. The mirror 27 is driven with a motor to vibrate the spot light at a constant speed at the right angle to the length of the groove 33 thereby making uneven intensity of the incident light uniform. Reflected lights from a member 25 are taken with a camera 29 to be received on a light receiving surface within the camera 29. An image processor 31 receives an image of the reflected light received with the camera 29 as electrical signal to determine the position at which the intensity of the reflected lights is at its minimum. Thus, the center position of the groove is calculated thereby assuring a higher accuracy of detecting a groove position.
