Title: Method for manufacturing magnet roll
Inventor: HIZUKA KYOTA
IPC: G03G15/09
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnet roll that does not require any complex facility, does not require any strict molding accuracy, can be inserted positively, and has a high torque resistance. SOLUTION: A magnet roll material 10 is formed by a binder that is made of a macromolecular compound and ferrite, and the diameter of a core metal insertion hole 13 is formed to be smaller than that of a core metal 11 to be inserted. The inner diameter of the core metal insertion hole 13 does not require a high accuracy. The binder is preferably made of elastomer resin with much emphasis on heat shock resistance or ethylene-ethylacrylate copolymer (EEA) when a high magnetic flux density is required. When the core metal 11 is inserted into the magnet roll material 10, the magnet roll material 10 is pinched between fixing tools 12 and 12, the core metal 11 is forced in from one side of the core metal insertion hole 13 with a sufficient insertion force, and is inserted to a specific position for completion, thus securing a sufficient torque resistance.

Filed: 1978-06-22
Abstract: PURPOSE: To lessen the number of processes, lower cost and produce the captioned material of high characteristics by applying silver plating processing on the surface of a Fe-Ni alloy being a base metal and heat-treating the same in an inert gas or hydrogen gas atmosphere thereby increasing the adhesion power between the base metal and silver deposit.  
     CONSTITUTION: After the Fe-Ni alloy is subjected to electrolytic degreasing and hydrochloric acid immersion treatment, it is subjected to high speed silver plating. Further, it is subjected to heat treatment. The heat treatment is performed in an atmosphere of single gas of inert gas or hydrogen or their mixed gases. The temperature should be within the range at which the characteristics such as hardness, spring characteristic and other of the electronic material will not be impaired and the heat treatment time should be within the time corresponding to such temperatures. For example, it is heat-treated for 30 seconds to 10 minutes at 400 to 700°C. This heat treatment improves and increases the adhesion power between the base metal and silver deposit of the Fe-Ni alloy and prevents the occurrence of stains and uneven coloring of the silver deposit. In addition, the need for etching and silver strike-plating is eliminated.
