Title: Method and apparatus for depositing amorphous silicon alloy
Inventor: MATSUDA AKIHISA
IPC: H01L21/205
Filed: 1986-11-07
Abstract: PURPOSE:To obtain a thin film of good quality in a shorter time by heating the discharge power supplying side electrode and/or the neighborhood of the discharge power supplying side electrode. CONSTITUTION:By heating a discharge power supplying side electrode 6 and/or the neighborhood of the discharge power supplying side electrode, the density of the raw material gas in the neighborhood of the discharge, power supplying side electrode 6 is lowered, thereby preventing discharge. That is, a highly polymerized powder, chain molecules (for instance, (SiH2)n) causing deterioration in the prepared film, and the like are generated by the reaction of the radical products of the raw material gas generated by high-energy electrons with another raw material gas, and accelerate the discharge between short electrodes as the chain length or size becomes large, generating and growing at a synergistic speed. This reaction is easy to occur in the neighborhood of the discharge power supplying side electrode 6 (cathode electrode) in which high-energy electrons is particularly concentrating, but this reaction can be prevented by reducing the raw material gas density in the neighborhood of the discharge power supplying side electrode 6.

Title: Erase control method for image forming device
Inventor: KAMEYAMA TOSHIAKI
IPC: G03G21/06
Filed: 1990-10-03
Abstract: PURPOSE:To prevent the degradation of the picture quality by specifying the arrangement of an erase means, a transfer means, and a sheet detecting means and erasing an unnecessary electrification potential at the time of detecting the trailing end of a transfer sheet or after the elapse of a prescribed time. CONSTITUTION:Respective means are arranged to satisfy relations A<=B where A is the distance from the transfer position of a transfer means 20 on a photosensitive body 18 to the erase position of an erase means 30 and B is the distance for which the transfer sheet is carried from the transfer position to the sheet detection position of a sheet detecting means 6. When the trailing end of the transfer sheet is detected by the sheet detecting means 6 or the prescribed time elapses, the erase means 30 is operated. Thus, the unnecessary electrification potential is erased without increasing the cost even if the size of the used transfer sheet cannot be detected, and the degradation of the picture quality is suppressed.
