摘要:
A persistent internal polarization (PIP) electrophotography printing system comprising at least one electrode of a discontinuous configuration, such as a foraminous conductive mesh, in combination with a PIP layer such that an electric field may be simultaneously applied to the PIP layer while permitting light radiation to reach the PIP layer. In the specific practice, the electrode is positioned adjacent to the surface of the PIP layer which is to be toned; that is, the top surface.

The present invention relates to the formation of electron spin EPR pairs and manipulation of such entangled electrons. The invention comprises a static quantum dot located part way along a quantum wire with means for adjusting the confining potential of the quantum dot. The quantum wire may for instance be formed by gate electrode (4, 6) with the quantum dot formed by a further gate electrode (8). The invention also comprises means for generating a electrostatic wave propagating along the wire, such as a surface acoustic wave transducer (10). In use a pair of electrons may be loaded into the static quantum dot and allowed to relax to a singlet ground state, in which the electrons are spin entangled. The propagating electrostatic wave acts as a series of quantum dots moving along the quantum wire. The confining potential of the static quantum dot is adjusted in time with arrival of a moving quantum dot so that one of the spin entangled electrons will tunnel to the moving quantum dot with preserved entanglement. The same process can be used to separately eject the remaining electron. The process can also be applied in reverse transport electrons from a moving quantum dot into a static dot.

To predispose toner particles to develop latent images in the form of polarized domains on a ferro-electric recording layer (12), for immediate transfer to a substrate (S), a donor roller (1) is rotated in a bath of liquid dispersed toner particles (4), which are charged; the thickness of the liquid dispersion, and hence of the quantity of donor particles, is controlled by limiting the amount of dispersant liquid toner particle deposit by rotating a limiting roller (9) positioned spaced apart with respect to said donor roller by a tiny gap; sequential rotation of the donor roller past a nkp (14) with the ferro-electric surface layer (12) forms a meniscu between the toner dispersion and, where the polarization of domains of the ferro-electric recording member (12) is opposite the charge polarization of the toner particles, the toner particles will adhere to the ferro-electric recording surface (12) for subsequent transfer to the recording substrate (S).

摘要:
An overcoated photoconductive material is uniformly illuminated in the presence of an electric field to create persistent internal polarization. Minute, translucent toner particles are then applied onto the surface of the photoconductive member, and a colored light image is projected onto the surface of the photoconductive member through the toner particles. Equal numbers of the toner particles are colored in three primary colors respectively to form a tri-color mosaic pattern on the surface of the photoconductive member. Each particle absorbs light of its complementary color during the imaging step so that the internal polarization is dissipated in a pattern corresponding to a colored positive of the light image as quantized by the colored mosaic of toner particles. The particles which absorbed light, constituting a colored negative of the light image, are then selectively frictionally removed from the surface of the photoconductive member since the charge holding them to the surface is weak. The remaining particles, constituting a quantized positive of the light image, are then electrostatically transferred to a sheet of recording paper and fixed thereto to provide a positive colored copy. The particles which absorbed light may also be electrostatically transferred to a sheet or film of recording medium as a negative colored copy.
