Title: Image forming device
Inventor: OGAMI HIROSHI
IPC: G03G15/08
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce the unevenness of an image and more average the worn state of a photoreceptor drum by uniforming the contact pressure of a roller part of a developing roller against the photoreceptor drum. SOLUTION: In development, a developing roller 14 is energized on a photoreceptor drum 11 side through second roller members 38a, 38b on a roller part side by first roller members 37a, 37b. Therefore, the contact pressure of a roll part 14b to the photoreceptor drum 11 is averaged over the whole body. Thus, the unevenness is minimized to uniform an image, and the worn state of the photoreceptor drum 11 is more averaged. Since each of the first roller members 37a, 37b is formed with a width of about 0.01-0.5mm so as to have a diameter smaller than the roll part 14b of the developing roller 14, the deforming quantity of the roller part 14b of the developing roller 14 is more satisfactorily controlled. Thus, the torsional moment generated in the roll part 14b is reduced, and the inbalanced state of the contact pressure is improved.

Title: Synchronizer ring
Inventor: NAKAMURA YOSHIKATSU
IPC: F16D23/02
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a synchronizer ring excellent in the inertial property and scuffing property by executing the steam process or the blast process and steam process to the inner peripheral surface which synchronously slides over at least a rotating opponent member and disengages from the opponent member. SOLUTION: Fine irregularities and numerous empty holes exist in the inner peripheral surface 101 of a sybchronizer ring made of a sintered body having 8-15μmRz of surface roughness. When the inner peripheral surface is subjected to the steam process at 550 deg.C-600 deg.C for 30-90min., a Fe304 coating having numerous empty holes of about 1μm of inner diameter is formed on the irregularity part of the surface to provide 20-25μmRz of surface roughness and about 500 of hardness. Thus, since the inner peripheral surface 101 has the increased surface roughness, an oil film formed on the contact surface between the inner peripheral surface and the opponent member is thinned.  As a result, the boundary lubricating condition is apt to take place and maintained so that though the coefficient of friction is heightened, the scuffing is prevented by the oiling effect of oil included in the empty holes in the Fe304 coating.
