Abstract: An apparatus and method that insures an even distribution of liquid in an aquatron charging device across the entire length of the device. This enables uniform charging across the width of the photoreceptor. The present invention fills and pressurizes a porous tube with a liquid. The liquid evenly exudes from the pores along the entire length of the porous tube. A hydrophilic liquid retentive foam which contacts the photoreceptor surface is wrapped snugly around the tube. The conductivity and overall rate of dispensation of liquid is controlled by the pressure differential across the porous tube.

Abstract: A new process to form a polycrystalline silicon film using a polycrystalline silicon-germanium (poly-Si.sub.1-x Ge.sub.x) capping film to "seed" crystallization of an amorphous silicon film on an upper surface of a substrate. The polycrystalline silicon film has no nucleation sites and a greater number of grain boundaries in the region near the polycrystalline silicon upper surface than in the region near the polycrystalline silicon and substrate upper surface interface. This indicates that crystallization and crystal growth occurred from the polycrystalline silicon upper surface and proceeded in a direction towards the substrate upper surface.

An amorphous silicon layer is formed over the substrate covering the plurality of silicon nucleation sites. The amorphous silicon layer is melted by using a laser beam and then crystallized to form the plurality of single silicon crystals. Each of the plurality of single silicon crystals correspond to one of the plurality of nucleation sites.

Abstract: A specific reflection area 42 on a paper surface 37a is irradiated with light from a light source 41 via nor not via a lens 43. A photoelectric conversion element 44 is placed on a focal surface in the rearward of the lens 43 and out of the light reflected (including scattering light and diffusion light) from the reflection area 42 on the paper surface 37a, only the whole light reflected within a predetermined angular range is received by the photoelectric conversion element 44 via the lens 43.

Among multiple display surfaces of each display element an optical property is selected according to an image signal and is visible through a transparent support to an observer. Afterwards, the attached state of each display element, i.e.

Abstract: A simple system for mechanically lifting and securing a copier/printer to vibration isolators aboard a Naval vessel. The system is compact, occupying space only under the copier/printer and not protruding from the sides and allows the copier/printer to completely detach for servicing. The system includes a four bar linkage using two square supporting members as the chassie with the four bar linkage being mounted to vibration isolators that are welded to the deck of the vessel. The four bar linkage is manipulated by two screws to easily and quickly raise the copier/printer off its casters and restrain it in a fixed position. The two screws make detachment from the four bar linkage a simple and time efficient process for repairpersons.
