Title: Developing device
Inventor: GOMI FUMIMITSU
IPC: G03G15/09
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To reduce fogging and to prolong the service life of toner, a developing sleeve or the like by impressing an alternate electric field whose peak value on a side where toner is restored from a photoreceptor drum to the developing sleeve side is smaller than the peak value on a side where the toner is moved to the photoreceptor drum side on a gap between the photoreceptor drum and the developing sleeve. SOLUTION: In the case of performing non-contact developing where a toner image is developed by forming the alternate electric field in the gap between the photoreceptor drum 1 and the developing sleeve 3, bias whose peak value on the side where the toner 6 is restored from the drum 1 to the sleeve 3 side is smaller than the peak value on the side where the toner 6 is moved to the drum 1 side is impressed on the gap between the drum 1 and the sleeve 3. It is desirable to set the maximum electric field at a part where the alternate electric field impressed on the gap between the drum 1 and the sleeve 3 alternately moves back and forth to 4.0×10<6> to 6.0×10<6> V/m and the frequency of the alternate electric field to 1.0 to 6.0kHz. Thus, a good-quality image is maintained over a long term even when a toner supply roller is in a non-contact state.

Title: Electron gun
Inventor: IGARASHI TSUNEHISA
IPC: H01J1/20
Filed: 1981-12-11
Abstract: PURPOSE:To offer an electron gun whose assembly work is simple and whose emission characteristic can be improved by connecting both ends of a heater with the first and the second stem lead wires respectively with regard to the electron gun for a view finder tube. CONSTITUTION:One end of a ceramic lead wire 14 is fixed to an outer sleeve 5 through a supporting piece 9 while the other end is welded to a stem lead wire 11. Also, the leading-out wires 7a and 7b of a heater 7 are directly welded to the stem lead wires 15 and 11 respectively. Accordingly one ceramic lead wire could be saved and also the number of the welding points of the ceramic lead wire to the stem lead wire could be reduced by one. Further, in the case of a former electron gun, the heater is welded to the ceramic lead wire in the course of a process so as to require shaping work of the ceramic lead wire but such work can now be omitted.
