Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To smoothly execute a printing job after the recovery of power while avoiding cost up with respect to a printer executing the printing job transmitted through a network from an external computer. SOLUTION: At the time of receiving a printing request from a networked computer, the printer stores the device identifier of the request source in a job managing table within a nonvolatile memory. When the power to the printer is interrupted by some trouble and the power is recovered after then, the presence/absence of an unprocessed printing job is confirmed by referring to the job managing table first (step S2). When the unprocessed printing job exists, an image transfer requesting packet is transmitted to the computer of the request source of the printing job (step S2) to request resending of image data concerning the printing job. When pertinent image data are transmitted from an external computer, the printing job is executed based on the image data.

Title: Manufacture of ceramic multilayered wiring board
Inventor: KAWAMINAMI SHUICHI

Filed: 1993-09-22
Abstract: PURPOSE:To remove binder in an oxidizing atmosphere, by forming paste by using copper conductor and silver-copper gradient powder, and sintering a laminate, which is formed by printing the conductive paste on green sheets and laminating them, in a non-oxidizing atmosphere, after removing binder in the outside air. CONSTITUTION:When silver-copper gradient composition powder is applied to conductive paste, oxidation of copper at the time of removal of binder is restrained nevertheless in the air by the effect of silver which is so contained in copper powder that the concentration is high on the surface and decreases with inclination. Hence the degree of oxidation is small, and the amount of generated copper oxide is little. As a result, it does not happen that the volume of copper expands and cracks are generated in conductor or a board. Since the amount of copper oxide generated at the time of removal of binder is little, volume contraction due to reduction at the time of baking is also little. The copper oxide is easily reduced in a short time, so that an excellent board wherein recess is not present and unevenness is little can be manufactured in a short time.
