Patent JP-H0220383-A (JP)
Title: Image formation
Inventor: INUI TOSHIJI
IPC: G03F7/00
Filed: 1988-07-08
Abstract: PURPOSE:To make possible the formation of an image at high speed and with low power consumption by providing the process to give optical energy or both optical energy and heat energy to a transfer-recording layer ahead of the process to form a transferred image. CONSTITUTION:A transfer-recording layer 1b provided on a support 1a which constitutes a recording medium 1 to be used, contains a material with sensitivity to light and heat. When light and heat energy are given, the polymerization of the components to be polymerized of said material occurs rapidly and the curing of the material follows. Thus the transfer characteristics change irreversi bly. In this method, prior to the formation of a transferred image, the degree of polymerization is increased in advance to N3 by the projection of light from a light projection means 2 for a time period of 0-t3, and later the heat and light energies are given for a time period of (t2-t3') by the light projection means 2 and a heating means 3 so that the degree of polymerization is further increased to N2. A transferred image is formed by allowing a transfer-recorded layer to undergo a reaction to a specified degree. In this manner, the time required for the formation of the transferred image is shortened and subsequent ly, the recoding of the image at high speed is made possible.

Title: Magnetic head and its production
Inventor: EGUCHI HIRONARI
IPC: G11B5/127
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration in the magnetic permeability of magnetic films at a high frequency and to improve the output characteristics of a magnetic head at the high frequency by specifying the film thickness of films for joining the magnetic head constituted by joining a pair of nonmagnetic substrates via magnetic films and the films for joining. SOLUTION: The magnetic permeability of the magnetic metallic films 13 exist as the major factor for governing the output characteristics of the magnetic head 10 at the high frequency. This magnetic permeability is deteriorated by the eddy current loss flowing to the magnetic metallic films 13 and the metallic films 14 for joining. The eddy current loss is larger as the film thickness of the magnetic metallic films 13 and the metallic films 14 for joining is larger and, therefore, the film thickness of the metallic films 14 for joining is regulated in order to suppress the deterioration in the magnetic permeability of the magnetic metallic films 13 by lessening the eddy current.  If the film thickness of the metallic films 14 for joining is <=300 nm, the magnetic permeability is kept at η50% even if the frequency is 40 MHz and the output characteristics of the magnetic head 10 at the high frequency may be improved. The film thickness of the metallic films 14 for joining is preferably specified to <=300 nm.
