Title: Manufacture of wiring board
Inventor: NAKAMURA NOBUYUKI
IPC: H01H11/04
Filed: 1992-02-27
Abstract: PURPOSE:To prevent the generation of pinholes, air gap and migration by printing a conductive paste on a board and by electrodepositing a resist material, which can be electrodeposited on a predetermined circuit pattern layer, so that a second insulating layer is formed on a first insulating layer. CONSTITUTION:A silver-fiber conductive past is printed on a glass epoxy substrate 10 by a screen printing method. After that, the silver-fiber conductive paste is hardened in a far infrared furnace so that a circuit pattern layer 11 is formed. Then, the substrate 10 is dipped in an epoxy insulating resist (EL), and electrodeposition is performed by the application of DC voltage with the use of the circuit pattern as an anode so that the circuit pattern layer 11 is covered with EL. Subsequently, EL is hardened in the far infrared furnace so that a electrodeposited insulating layer 12 is formed. Then, an epoxy solder resist is printed on the whole surface of the substrate 10 containing the electrodeposited insulating layer 12 and hardened so that an insulating layer 13 is formed. Thus, it is possible to obtain a wiring board displaying an excellent migration resistance.

Abstract: PURPOSE: To enable images of good reproducibility without ground fog to be formed by using one component developer consisting of particles of the type which the conductive regions where charges are movable scatter in the insulation type main regions of the surface.  
     CONSTITUTION: Toner particles consist of insulation type substrates T' having insulation type surfaces and conductors T" which expose on their surfaces and in which charges can move. In a static state, they have insulation properties as a whole. The toners T 1  thru T 8  carried on a developer carrier 9 form a developer layer on the carrier 9 and the surface portions thereof touch the surface of a photoreceptor 1'. At this time, an electrostatic field is formed by the charges of this image part A in their regions of the electrostatic image part A, and at the time when the toners T 1  and T 2  are separated by certian force, the toner T 1  assumes the state of being charged negative and is attracted in the image part A direction and the toner T 2  goes away from the image part A. Since no electrostatic field is formed in the region of the non-image part B, electrostatic induction phenomena like the toners T 5 , T 6  do not occur.
