Abstract: PURPOSE:To enable a large number of same copies to be made at high speed, by injecting charge to the center or central layer of a composite semiconductor on a conductive substrate, illuminating the composite semiconductor with light, applying toner to it in accordance with charge captured, and transferring the toner to the surface to be printed on. CONSTITUTION:A composite photosensitive semiconductor 1 is formed on a conductive substrate 2, and consists of a semiconductor layer 3, an insulating or semiinsulating layer 4, a charge capturing central layer (hence TL) 5, and an insulating layer 6 each laminated in succession. An electric field is applied between the substrate 2 and an electrostatic charge generating source on the semiconductor 1, and positive charge is captured through the surface of the semiconductor 1 with TL 5. Light 10 is projected locally, releasing the positive charges on regions 7, 7', 7'' to the conductor 2. Negative electrons neutralize the positive charge in TL 5 or on the surface to selectively distribute on the semiconductor 1. The charge on the surface is erased by attaching and removing toner, but the charge in TL 5 remains as it is, permitting high speed copying without requiring charging and destaticizing at each time one copy is made during multiple copying.

IPC: B21D37/10
Filed: 1981-09-09
Abstract: PURPOSE:To obtain a quickly workable and durable die material economically by using, as the base material for die, a compound body made by unifying a surface metal consisting of high alloy tool steel and a base metal consisting of structural alloy steel. CONSTITUTION:Base material 1 for die is made by forge welding or brazing a surface metal over whole surface of a base metal forming a base to unify the two. In case where the surface metal is die steel, it is unified by forge welding. The process is carried out in the following sequence: heating, rolling forge welding (compounding and unifying), normalizing, annealing, hardening and tempering. After this, it is finished by grinding the upper and lower faces. For the base metal 2, steel having hardness of HR C20-40 after heat treatment is used to permit drilling and tapping. In case where the surface metal is high speed steel, the base metal 2 and surface metal 3 are usually compounded and unified by brazing though forge welding is sometimes used. At this time, brazing filler metal is inserted between the two, and hardening is performed at the same time. After brazing and hardening, it is tempered and upper and lower faces are finished by grinding to obtain a base material 1 for die.
