Title: Electrophotographic method
Inventor: TSUCHIYA HIROAKI
IPC: G03G21/00
Filed: 1980-02-12
Abstract: PURPOSE:To obtain sharp images of high quality rapidly at all times by changing the quantity of the coronas applied upon a photoreceptor according to the kinds of originals thereby changing the potential curve of the latent images from a black color original which is a reference up to a white color original. CONSTITUTION:At the time of forming latent images on a photoreceptor 1 by exposing images thereto by the DC coronas from the 1st corona discharger 2 and the AC coronas from the 2nd corona discharger 3 then irradiating the entire surface with a lamp 4, a potential sensor 10 is provided on the lower stream of the corona discharger 3, and the latent image potential of the photoreceptor 1 in the state that the original exposure lamp is held put out and the latent image potential corresponding to the white color original are measured. These measured values are fed back to a control part 11 and the currents to be applied to the dischargers 2, 3 are thereby changed in order to form the latent images based on the preset potential curve depending upon the kinds of the originals on the photoreceptor 1. In this way, the originals having varying densities or having colors on the background to make photographic fog easy to occur are copied always sharply despite the change in environmental atmosphere or the change in the photosensitive characteristics of the photoreceptor 1.

Abstract: PURPOSE:To substantially reduce the parasitic capacity between input and output for improving the high-frequency characteristics, by providing a recess at the center of the rear face of an insulative substrate and arranging a plurality of metallized layers so as to surround the recess. CONSTITUTION:A ceramic base 1 has a recess 18 at the center on the rear face side thereof. This recess 18 preferably has a depth corresponding to at least 50% of the thickness of the ceramic base 1. Rear face metallized layers 12, 13 and 5a, 5b are arranged so as to surround the recess 18. By forming the recess 18 in such a manner, an air gap is provided partially within and in series with the ceramic interposed between the metallized layers 8 and 9. Therefore, the dielectric constant of this section becomes 1/10 of that of alumina, and the electrostatic capacity as a parallel-plate capacitor is substantially reduced. This recess 18 also reduces the gap capacitance generated between the metallized layers 12 and 13 by the same reason. Accordingly, the parasitic capacity can be substantially recuded as a whole.
