IPC: B22F9/04
Filed: 1988-10-20
Abstract: PURPOSE:To make a molded substance dense at a low temperature, to prevent crystal particles from becoming coarse and to enhance the coercive force by a method wherein an alloy ingot is crushed fine, it is molded under a hot pressure or in a magnetic field and, after that, an obtained molded substance is crushed. CONSTITUTION:Nd at a purity of 97wt.% (the rest part is constituted of other rare-earth elements composed mainly of Ce and Pr), a ferroboron (pure B content, 20wt.%) and electrolytic iron are used; they are melted by a high-frequency heating operation in an atmosphere of argon so as to obtain 34.0wt.% of rare- earth elements (R), 1.0wt.% of B and Fe for their remaining part; an alloy ingot is obtained. Then, after this ingot has been crushed coarsely, it is crushed fine by using a ball mill. Then, this alloy powder is hot-pressed and a molded substance is obtained. Then, after this molded substance has been crushed, it is heated in an atmosphere of Ar and quenched. A crystal orientation degree of a powder obtained by crushing the molded substance is high; a rare that magnetic particles are exposed on the surface is low; accordingly, the powder has a high coercive force.

Title: Production of printing head
Inventor: TAJIMA JOJI
IPC: B41J2/335
Filed: 1989-10-09
Abstract: PURPOSE:To form heating resistor layers accurately without the possibility of contacting with each other even at a smaller pitch by a method wherein a heating conductive ink adheres within an open part of a resist layer, the resist layer is released but the conductive ink in the open part remains, and the heating resistor layer made of the conductive ink is formed in a gap part of a wiring lead. CONSTITUTION:A heating conductive ink 16, such as a carbon ink, is printed along an open part 15 of a photo resist 12. The conductive ink 16 can be printed by charging a sufficient amount of the ink 16 in the open part 15 of the photo resist 12. Thereafter, the photo resist 12 is released with a release liquid. Then, the unwanted conductive ink 16 adhering on the top surface of the photo resist 12 is simultaneously removed together with the photo resist 12. However, the conductive ink 16 adhering in the open part 15 remains intact. This remaining conductive ink 16 is dried and cured, whereby a heating resistor layer 17 made of the conductive ink 16 is formed in a gap part 7 of a wiring lead 4. Because the heating resistor layer 7 is formed by charging the conductive ink 16 in each of the open parts 15, the contact of adjacent heating resistor layers 17 with each other can be prevented.

Abstract: PURPOSE:To stabilize an actual fixing temperature and to prevent the occurrence of high temperature offset and defective fixation by making a heat roller and a pressure roller idle (aging) for a specified time, and detecting the temperature of the heat roller and correcting a control temperature. CONSTITUTION:Before a 1st time of turning on a heater 59, the heat roller 54a and the pressure roller 54b are made idle (what is called 'aging') for the specified time, and the temperatures of both rollers 54a and 54b are made uniform. and just after this, the temperature of the heat roller 54a is detected, the temperature of the pressure roller 54a is reflected on the detected temperature (t1).
