Title: Fabrication of resistance element
Inventor: KURAMOTO MASAMICHI
IPC: H01C7/02
Filed: 1991-03-05
Abstract: PURPOSE:To provide a method of fabrication of a PTC resistance element which is safe, inexpensive and further excellent in a temperature characteristic. CONSTITUTION:Upon firing of a PTC resistance element, the firing is carried out in a nitrogen atmosphere instead of a hydrogen atmosphere. With hydrogen used as the firing atmosphere, costs such as that of a facility therefor are high and further hydrogen is inflammable and is unlikely to ensure safety. On the contrary, nitrogen is inexpensive and excellent in safety and a PTC resistance element yielded by firing thereof in a nitrogen atmosphere ensures a substantially identical PTC characteristic to that yielded in a hydrogen atmosphere. Thus, a safe and low-cost method of fabrication of the PTC resistance element excellent in the PTC characteristic is ensured by carrying out the firing in the nitrogen atmosphere.

Title: Electrophotographic copier
Inventor: OOTSUKA SHIYUUICHI
IPC: G03G15/14
Filed: 1980-03-26
Abstract: PURPOSE:To make possible the transfer of electrostatic latent images or toner images having many changes in copying magnification by rolling a photoreceptor with respect to the projected image plane of a static exposure optical system and further driving a transfer material thereby performing transfer. CONSTITUTION:An optical image is formed on an optical image forming plane 2-2 by a lens 2-1 of a static optical system, and is exposed through a slit 2-11 onto a photosensitive drum 2-0 which is uniformly charged with a corona charger 2-3. The electrostatic latent image is transferred to electrostatic recording paper 2-7 between said drum and an electrostatic latent image transfer roll 2-4. In this case, the drum 2-0 moves from the left to right at the speed Vp, at the same time of which it is subjected to exposure and transfer of the electrostatic latent image while revolving counterclockwise at the angular velocity W. The transfer ends at the point of the time when the drum moved to the right end. the recording paper cut to the length L of the exposure part where the drum moves is so controlled that its trailing end passes the drum transfer part. Since the roll 2-4 is driven by the drum 2-0, there is virtually no difference in the moving speeds of the recording paper and the transfer part, thus the transfer free from deviation is accomplished.
