Title: Intermediate transfer medium and image forming device
Inventor: TANAKA ATSUSHI
IPC: G03G15/16
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation in the resistance of an intermediate transfer medium during the life thereof and to obtain image which are extremely little in splashing in spite of repetitive use by having at least either of a nitric acid ion adsorption material and a compound having a laminar structure on the surface of the intermediate transfer medium. SOLUTION: The surface of the intermediate transfer medium has at least either of the nitric acid ion adsorption material and the compound having the laminar structure. When the nitric acid ion adsorption material is subjected to a surface treatment, such as a hydrophobing treatment, the electric resistance value of the nitric acid ion adsorption material itself is hardly affected by humidity and the degradation in the electric resistance value of the intermediate transfer medium in a highly moist environment may be sufficiently prevented. Further, the compound (laminar compound) having the laminar structure captures nitric acid ions between the layers, thereby preventing the degradation in the resistance of the intermediate transfer medium. The examples of such laminar compound include kaolin, mica, etc. More preferable examples are specific hydrotalcite compounds.

Abstract: PURPOSE:To control consuming electric current into the mininum limit and permit a high energy control with the least electric power consumption by a method wherein a DC-DC converter is operated for only a predetermined period of time after receiving an ignition signal. CONSTITUTION:A trigger voltage Vt, in accordance with the revolving number of an engine in any revolving number, is generated to control the correct timing of an ignition spark by a method wherein a comparator 7 is employed in the voltage input circuit of a pickup 3 so that the output of the pickup is brought into HIGH compared with the reference voltage of the comparator 7 even when a pickup voltage Vp is fluctuated. In this case, a desired charging voltage Vc= 300-400V can be achieved by 3-4 pieces of charge pulse current for the capacitor C5 in about 0.8msec of necessary time and thus the timing of the ignition spark may be controlled correctly and freely by the adjustment of one shot pulse width. Further, the interval of pulase becomes 3.64msec at 11,000rpm of engine revolving number and the current ic is not flowed through the primary and secondary coil of a booster transformer 5 during 2.84msec, from which said 0.8msec is subtracted, thereby enabling to reduce the power consumption.
