Title: Heating element for conduction recording
Inventor: SHIMURA YOSHITOMO
IPC: B41J2/32
Filed: 1987-02-24
Abstract: PURPOSE:To perform the modulation of a recording energy over a wide range easily and accurately at a high speed, and enable repeated use by a method wherein a metal conductive layer is made of a deposition film of a metal selected from among gold, silver, and pratinum group elements coming under the group-VIII of the periodic table. CONSTITUTION:In recording, a resistant layer 1 is heated by passing an electric current between a recording electrode 11 and a return electrode 12 by a signal current 13. However, if an interface layer having non-ohmic electric characteristics exists between the resistant layer 1 and a conductive layer 2, the modulation becomes hard to realize because of the irregular heat-generation of the interface layer. To impart ohmic and stable electric-resistance characteristics to the interface between the resistant layer 1 and the conductive layer 2, the conductive layer 2 is formed by a method in which a metal selected from among gold, silver, and pratinum group elements coming under the group-VIII of the periodic table is vacuum-deposited to be a film of 20-300Angstrom  thick, and desirably an aluminum-deposition layer of 300-2000Angstrom  thick is further formed thereon. In this manner, a remarkably low and stable resistance can be established between the resistant layer 1 and the conductive layer 2. Namely, an aluminum vacuum deposition layer 22 is formed on a metal-deposition film 21.

Abstract: PURPOSE:To prevent the change of the width of a conductor between a metallic sheet and a lead section, and to obviate current concentration in the lead section by bending the metallic sheet in the width direction of a winding under the state in which the metallic sheet is superposed on an insulating sheet and using the terminal section of the metallic sheet as the lead section as it is.
