Title: Transferring and separating method of copying machine
Inventor: SAKAI TOSHIO
IPC: G03G13/16
Filed: 1979-10-17
Abstract: PURPOSE: To make the separation of transfer material sure by closely adhering the transfer material to an electrostatic latent image carrying body surface having toner images then subjecting the same to corona discharging of the polarity opposite to that of the latent images thence superposing a dielectric separating material on the transfer material and subjecting the same to corona discharging of the polarity opposited to that of the latent images from its back.  
     CONSTITUTION: At the time of transferring the toner images on a photoreceptor (drum) 1 to transfer material (transfer paper) 3 and separating the transfer material 3 by means of a dielectric separating member (endless belt) 4, the transfer material 3 is subjected to the discharging by a corona discharger 9 of the polarity opposite to that of the latent images of the photoconductor of the photoreceptor 1, from its back. Thence, the dielectric separating member 4 is superposed on the transfer material 3 and is subjected to corona discharging 2 of the same polarity as that of the latent images. In this way, the transfer and separation of the transfer material 3 from the photoreceptor 1 are surely accomplished even in a dry environment, and the good transfer images may be obtained.

Title: Fabrication of semiconductor device
Inventor: MIWA HIROYUKI
IPC: H01L21/8249
Filed: 1992-04-27
Abstract: PURPOSE:To improve characteristics of bipolar transistor by coating a bipolar transistor forming region with a gate forming material at the time of forming the gate of MOS transistor and employing the bipolar transistor forming region thus coated as the base electrode of bipolar transistor thereby preventing increase of parasitic capacitance and decrease of integration due to increase of size. CONSTITUTION:When a side wall oxide 33 is deposited in a gate forming region 32 of MOS transistor by etching back the entire surface through RIE, the RIE causes no damage nor deterioration of characteristics because the bipolar transistor forming region is coated, at the active part thereof, with a gate forming material, i.e., a gate oxide 31. Since the gate forming material is employed as the base electrode of bipolar transistor, distance between the emitter and base electrodes is shortened remarkably as compared with the conventional case and thereby parasitic capacitance is reduced and high integration is realized through reduction of element area resulting in the improvement of characteristics.
