Title: Polarized electron beam generating element
Inventor: NAKANISHI TSUTOMU
IPC: H01J1/34
Filed: 1991-05-02
Abstract: PURPOSE:To obtain more than or equal to 85% of polar deflection by making hetero-junction between a first and a second compound semiconductor layers having different lattice constants, and determining each lattice constant to make the energy levels of sub-bands of heavy holes and light holes of the second layer which generates polarized electron beam larger than heat noise energy. CONSTITUTION:On for example, a P-type GaAs substrate 12 doped with Zn and having 5X10<18>/cm<3> of a carrier concentration and about 350mum thickness, a first P-type GaAs layer 14 which is a P-type GaAs having the same carrier concentration and 2.0mum thickness and a second P-type GaAs layer 16 which is the same as layer 14 but whose thickness is 0.08mum are successively formed and grown. In this way, the thickness of the layer 16 is made thicker than the critical layer thickness to carry out coherent growth, so that the lattice constants of the layers 14, 16 differ each other by about 0.6% and while lattice strain is formed in the layer 16, hetero-junction is formed on the layer 14. An energy level is thus generated in the heavy and light sub-band in the valence band of the layer 16.

Abstract: PURPOSE:To exactly execute separation from the surface of a drum tip part of a transfer material, and also to eliminate a retransfer (transfer failure), by controlling a destaticizing corona current without turning on and off a corona  generating electric power supply or switching an applied voltage. CONSTITUTION:To an electric discharge wire 32, prescribed voltage is applied by a constant-voltage transformer or a constant-current transformer simultaneously with a copying operation. In this case, when a lamp 34 is in a turned-off state, a photoconductive body layer 33 of the inside surface of a destaticizer shield 31 operates as an insulator layer, as a result, most of corona ions from the wire 32 flow in the direction of a drum 1. On the other hand, in case of a state that the lamp 34 is turned on and light is irradiated to the photoconductive body layer 33, the layer 33 becomes conductive and operates as an electric conductor, and as a result, most of corona ions from the wire 32 flow to the shield 31 side. That is to say, by controlling turn-on and turn-off of the lamp 34 when the destaticizer 3 is operated, in accordance with said control, the quantity of a corona ion, that is to say, the quantity of a current in the direction of the drum 1 can be switched and controlled easily as to its magnitude, without controlling the applied voltage to the electric discharge wire 32.

Filed: 1984-06-28
Abstract: PURPOSE:To attain the stable number of revolution control by detecting noise in a reproduced video signal and applying an average value of an H synchronizing frequency detection signal to a disc motor turning control system without using an H synchronizing signal during noise period to improve the transient characteristic of a control loop. CONSTITUTION:While an H synchronizing signal 500 is disturbed by the noise in a reproduced video signal at vari-speed reproduction, a gate circuit 17 blocks the input of an H synchronizing frequency detection signal 600 inputted to a disc motor turning control loop and inputs an average value of the signal 600 instead. Then the number of revolution control of the disc motor 14 is executed stably to correct completely the H synchronizing frequency deviation by vari-speed reproduction. Since a filter or the like having a large time constant is not fed in the H synchronizing signal input loop, the response at the transient state of the disc motor turning control loop is kept in an excellent way and the large deviation of the H synchronizing signal is not caused even when the transition from the normal reproduction mode to the vari-speed reproduction molde.

IPC: G03G15/00
Filed: 1981-08-24
Abstract: PURPOSE:To prevent a stain of a transfer material guide at low or high humidity, by constituting a lower guide of the transfer material with a conductive member, and forming a high polymer material having a small friction coefficient and <=10<6>OMEGAcm electric resistance on the lower guide surface and grounding the lower guide via a constant-voltage element. CONSTITUTION:The upper and lower guides 2 and 3 guide a transfer material P to a copying part. The guide 3 is formed with a conductive member, and a high polymer material layer 3a is formed on the surface of the guide 3. The high polymer material has a small friction coefficient to the material P with a conducting process applied to ensure approximately <=10<6>OMEGAcm electric resistance. Furthermore the material P is grounded via a constant voltage element such as a varister 7. A varister 7 of rated 600V, for example, is used to keep the potential of the guide 3 at 500-700V even in the high humidity circumferences.  Thus the deteroration of copy quality caused with high humidity can be avoided, and at the same time a stain caused on the rear of an image with the normal  or low humidity can be prevented.
