Title: Method for manufacture of insulating film for iron core
Inventor: GOHISA TOSHIO
IPC: H02K15/12
Filed: 1979-02-14
Abstract: PURPOSE: To increase the thickness of the insulating film for the end portion of an iron core by concentrating positive charge at both ends of the core after electrostatically applying positively charged insulating power on the core, and performing electrostatic painting again by negatively charged insulating powder.  
     CONSTITUTION: Insulating powder 10 is positively charged by a main electrode 8, and electrostatic painting is applied on a negative iron core 12 which is at a negative potential. When a specified amount of the insulating powder is deposited and an electrostatic repelling force begins to operate, both the iron core 12 and the main electrode 8 are made to be a zero potential. Then, auxiliary electrodes 14 are arranged so as to oppose both end surfaces 3 of the iron core 12, and a weak electric field of a negative potential is applied in order to concentrate positive potential at both ends of the iron core and to charge floating insulating powder 10 to a negative potential, thereby the second paint film 15 is formed on the end surface of the iron core 12. In this method, the thickness of the insulator on the core-end surface 3 is increased, and the insulation at an angle portion 7 such as slot openings can be made secure.

Abstract: PURPOSE:To form a microscopic contact window having an excellent degree of uniformity by a method wherein, when the contact window is going to be provided, the transverse oxidization is positively utilized when a selective oxidization is performed. CONSTITUTION:A polycrystalline Si film 3 is coated on the insulating film 2 covering the substrate 1 whereon each electrode was formed, and an Si3N4 film 4 is coated on the film 3. Then, the film 4 located on the contact window forming region only is left and the film 4 on all the other regions is removed. Subsequently, a thermal oxide film 31 is formed on the film 3, which was formed below the film 4, by performing a high temperature heat treatment in an oxygenous atmosphere using the remaining film 4 as a mask, and it is used as an interlayer insulating film. Lastly, the conact window is formed by removing the film 4, the film 3 located directly below the film 4, and the insulating film of the bottom layer. While these procedures are performed, transverse oxidization is generated due to high temperature heating when the selective oxidization was performed, and the contact window smaller than the width of the film 4 can be formed.

IPC: G03G15/20
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent a heater from being cracked at its secondary side end when the temperature of the heater abnormally rises while excellently heating an image by making the depth of the counterbore part of a thermoplastic supporting member corresponding to the end of a resistance heating element smaller than that of the thermoplastic supporting member corresponding to the central part thereof. SOLUTION: The calorific value is set larger at the end of the resistance heating element 104 of a surface heater 101 than at the central part thereof. When the temperature of the heater 101 abnormally rises, the shallow bearing surface of the counterbore part 111 of the thermoplastic supporting base 102 at the end of the element 104 of the heater 101 is melted first. Then, the depth of the counterbore part 110 of the base 102 at the end of the element 104 of the heater 101 becomes constant, and the entire back surface of the end of the element 104 of the heater 101 touches the base 102. Thus, the temperature rise at the end of the element 104 of the heater 101 is reduced and the heater 101 is prevented from being cracked at the end of the element 104 thereof.
