Title: Transfer device of electrophotographic copier
Inventor: YASUDA TADAHIRO
IPC: G03G15/00
Filed: 1979-12-26
Abstract: PURPOSE: To enable stable transfer characteristics to be obtained and enable the copied image of uniform and good quality to be formed by so arranging the device that proper current flows in transfer paper even in the state that the resistance value of the transfer paper has been lowered in high humidity environment.  
     CONSTITUTION: A conveying roller 51 as a field stabilizing member consisting of a metallic body insulated from the ground is disposed near a transfer roller 21 which is a transfer field applying device. This conveying roller 51 is connected via a variable resistance 52 for current controlling to a power source having nearly the same auxiliary bias voltage E 0  as the bias voltage E of the transfer roller 21. The transfer roller 21 per se is connected via controlling resistance 53 to the power source having the bias voltage E so that optimum current flows to a toner image transfer part 16. As a result, the dissipation of the charge for transfer field applied from the transfer roller 21 is prevented by the replenishment of the charge from the conveying roller 51, whereby the formation of a fogged latent image is prevented simultaneously.

Title: Photomask and production thereof
Inventor: OHASHI YUMIKO
IPC: G03F1/80
Filed: 1989-07-05
Abstract: PURPOSE:To obtain the mask having good pattern accuracy by ending the etching of a metallic film or metal compd. which is a light shielding film before a substrate is exposed. CONSTITUTION:An iron oxide film 2 is deposited by a high-frequency sputtering method on one surface of the glass substrate 1. A positive type resist 13 is applied by a spin coater on the iron oxide film 2. This resist 13 is selectively exposed by an argon laser 14. The substrate is immersed into a developing soln. of an alkaline system to remove soluble parts and to expose the iron oxide film 2. The developing is ended before the glass substrate 1 is exposed without completely removing the iron oxide film at this time. The photomask produced in such a manner ends the etching before the etching arrives at the glass substrate in the etching stage and, therefore, the local excessive etching by the etching liquid penetrated between the iron oxide film and the photoresist is prevented. The patterns having the high accuracy are thus formed.

Filed: 1988-07-12
Abstract: PURPOSE:To change a conductivity type from an N<-> type to a P<-> type, and to obtain an enhancement-driven TFT by a simple constitution by forming a BSG film between a poly-Si active layer and an insulating substrate in the N channel TFT and thermally diffusing boron in the BSG film into the poly-Si active layer in a heating process. CONSTITUTION:A BSG film 10 is shaped onto an insulating substrate 9, a poly-Si thin film is deposited onto the BSG film, and a poly-Si active layer 11 is formed through patterning. A thermal oxide film 12 is formed by thermally oxidizing the poly-Si active layer. Since a thermal oxidation process is executed normally at a temperature of 1000 deg.C, boron in the BSG film is thermally diffused into the poly-Si active layer, and a P<-> poly-Si active layer 13 is shaped. Source-drain regions, a gate electrode, a contact electrode, etc., are formed through a normal process, thus manufacturing an N channel TFT. The N channel TFT manufactured in this manner functions as an enhancement type because the active layer is shaped in a P<-> type.
