IPC: H02K15/12
Filed: 1980-12-02
Abstract: PURPOSE:To improve the insulating characteristic of the region adjoining to the jut of an insulating conductor for the subject stator by a method wherein, before  inserting the insulating conductor, a mold releasing material is interposed between the region in the vicinity of the jut of the insulating conductor and the surface of the conductor slot opposing the above. CONSTITUTION:Before the insulating conductor 2 is assembled in the conductor slot 3, the mold releasing material 7, which was formed by such a mold releasing tape as one marked X in the diagram, is provided on the outside of the insulating conductor 2 located in the vicinity of the outlet N of the slot. This mold releasing material 7 is then assembled in the slot 3, and after the assembling work has been finished, insulating varnish is filled in the slot, and the insulating conductor 2 and the slot 3 are fixed in a body. Through these procedures, as the insulating conductor 2 and the slot 3 are released from the mold, without adhereing, in the vicinity of the slot outlet N, only bending stress is applied to the insulating layer of the insulating conductor 2 in the vicinity of the slot outlet N and no shearing stress is applied, thereby enabling to lessen the stress as well as to improve the insulating characteristic of the region in the vicinity of the slot outlet N.

Abstract: PURPOSE:To attain picture reading with fidelity to an original by coating an upper face of a shield member with a black paint, forming a transparent section as a slit shape and limiting the range of the original to be lighted. CONSTITUTION:A shield member 9 is provided at a read position 5 and when an original S is carried in a carry path L, the member acts like a guide.

Then the light from a light source 4 is subjected to limit of the range lighted by the original S because the transparent part is shaped as a slit resulting that the region playing a role in the secondary light source is made narrow. Then a read means does not read the information other than the prescribed picture information and reads the density information of the original S with fidelity thereby improving the picture quality.
