Title: Magnetic sheet absorption head
Inventor: TAKAHASHI TAKUMI
IPC: H01F41/04
Filed: 1992-11-30
Abstract: PURPOSE:To attract and release a magnetic sheet securely by providing an actuator in which a core of an electromagnet can be freely moved in a separating direction to the attraction surface for attracting the magnetic sheet and the core is moved to a head body in the same direction. CONSTITUTION:A magnetic sheet attraction head has an electromagnet 2 generating a magnetic field for attracting a magnetic sheet 9 to the flat bottom surface of a head body 1. In an actuator 5, a core 4 of the electromagnet 2 can be freely moved in a separating direction to the attraction surface for attracting the magnetic sheet 9 and the core 4 can be moved to the head body 1 in the same direction. In this case, the actuator 5 such as a solenoid is designed to operate in synchronization with the ON-OFF of the electromagnet 2 so that the core 4 is separated from the attraction surface when the electromagnet 2 is released and the core 4 approaches the attraction surface when the electromagnet 2 is excited. Thus, the influence of the magnetic field on the attraction surface from the side of the attraction head can be eliminated when the attraction of the magnetic sheet 9 is released.

IPC: H05K3/06
Filed: 1991-12-26
Abstract: PURPOSE:To prevent a drop in adhesion strength with an insulation material of conductor patterns by allowing gold to adhere to a metal foil portion to be removed when forming the conductor patterns. CONSTITUTION:A noble metal catalyst 3 is bonded with a copper-clad laminated board where a copper foil is applied to an insulation material 2 where the noble metal serves as a catalyst during etching time. After the laminated board is covered with a dry film which is a plating resist 4, a portion, which forms a conductor pattern based on a photograph process, is eliminated, thereby forming a plating resist 4'. Then, a conductor pattern 5 is formed by a chemical plating process. A metal, which serves as an etching resist 6, is formed on the conductor pattern 5 and the plating resist 4' is separated and removed by means of a solvent. After the removal, metal foil portions which exclude the conductor pattern 5 or more specifically the base material 1 which is the copper foil is etched and eliminated. Moreover, the solder portion, which is the etching resist 6, is eliminated. This construction makes it possible to reduce leaching on the sides and the base of the conductor pattern 5 and protect the conductor pattern 5 from being separated from the board.
