Title: Powder high-speed tool steel
Inventor: NISHIDA JUNICHI
IPC: C22C38/00
Filed: 1990-10-31
Abstract: PURPOSE:To improve a high-temperature tempering resistance characteristic and to give high wear resistance and high toughness by regulating the amounts of W and Mo in steel composition, their relation, and C-Ceq within specific ranges. CONSTITUTION:The powder high-speed tool steel consists of over 1.5-2.2wt.% C, <=1.0wt.% Si, <=0.6wt.% Mn, 3.0-6.0wt.% Cr, 20-30wt.% W+2Mo and >=1wt.% W/2Mo, <=5.0wt.% V, 2.0-7.0wt.% Nb, where Nb/V is >=0.5wt.%, and Fe and unavoidable impurities for the rest. Further, the amount of C is so adjusted that C-Ceq is-0.15-0.05. Here, Ceq=O.24+0.033.W+0.063.Mo+0.2V+0.1.Nb. With this composition, the high-temperature softening resistance characteristic is improved and the wear resistance at high temperature is improved. Although crystal particles are still very fine, the toughness is high, so the life is prolonged under the high-speed conditions of a tool.

IPC: G03G15/06
Filed: 1999-10-18
Abstract: PROBLEM TO BE SOLVED: To sufficiently obtain image density and to obtain the images free of the defect by abnormal discharge by preventing the rough feel of highlight parts by applying an adequate development bias. SOLUTION: The BP bias consisting of a quiescent part and vibration part is impressed as the development bias to a developing sleeve. The vibration part of the BP bias is formed of four pulses and 900 V is impressed to the developing sleeve as an electric field to pull back toners to the sleeve right after the quiescent part and -900 V with respect to a blank potential is impressed thereto and further 900 V with respect to the blank potential is impressed thereto. Finally, -900 V is impressed to the sleeve in the direction of splashing the toners to a photosensitive drum and thereafter the quiescent part comes.  If the developing sleeve potential overshoots with respect to the blank potential when the vibration part changes to the quiescent part, the degradation in developability occurs and, therefore the vibration part is gently connected to the quiescent part by spending the time T2=50 μs in order to prevent the same.
