A photosensitive drum for image forming apparatus includes an inner roller, an outer roller and a photoelectric conversion layer. The inner roller of circular cylindrical shape is formed by a cathode substrate. The outer surface of the circular cylinder is configured with a plurality of cathode units. The outer roller of hollow circular cylindrical shape is formed by an anode substrate. The inner diameter of the outer roller is greater than that of the inner roller such that the inner roller is snugly fitted inside the outer roller. The anode substrate includes a plurality of anode units corresponding to the cathode units. The photoelectric conversion layer is a hollow circular cylinder with an inner diameter greater than the outer diameter of the outer roller such that photoelectric conversion layer is snugly fitted onto the surface of the outer roller. An electric potential difference is applied on the cathode substrate to induce the electron beam generated by the cathode unit to impinge on the anode unit to produce light. The generated light is directly converted into electrostatic by the photoelectric conversion layer to adsorb on the surface thereof to adsorb toner powder. The toner on the surface of the photosensitive drum is then transferred and fused on paper to form image.

A tetraode field-emission display and a method of fabricating the same are disclosed. A mesh is disposed between an anode plate and a cathode plate. The mesh has a gate layer and a converging electrode layer separated by an insulation layer to form a sandwich structure. The mesh has a plurality of apertures in correspondence with each set of anode and cathode. The converging electrode layer is facing the anode plate, such that the divergent range of an electron beam emitted by an electron emission source can be restricted. Thereby, the electron beam can impinge the corresponding anode more precisely.

A laminate oleophilic reformative clay and a method of production for the same are described, and a material and method of production for ABS nano-metric composite material produced by the same are also described. The ABS nano-metric composite material is waterproof for a self-cleaning ability and has enhanced strength. The cost to produce the ABS nano-metric composite material is also reasonable. The ABS nano-metric composite material is made of ABS substrate formed from ABS material and laminate oleophilic reformative clay uniformly distributed in the ABS substrate.

A electron beam etching apparatus uses carbon nanotube as electron emitter. The electron beam etching apparatus includes a vacuum chamber, a cathode plate, an anode plate and a driver unit. The cathode plate and the anode plate are arranged in the vacuum chamber and parallel to each other. The cathode plate includes a plurality of cathode units, where each of the cathode units uses a carbon nanotube as an electron emitter. A gate conductive layer is provided atop the cathode unit. The anode plate includes a substrate and an etching target. The driver unit is electrically connected to the cathode unit and gate conductive layer. The driver unit controls the cathode unit through the gate conductive layer to generate electron beam for etching. The accuracy of etching process can be improved and the cathode unit has the advantage of replacement possibility.

An X-ray machine being able to irradiate a narrowed portion within a maximum irradiation range through a control to the electrodes of an X-ray generator is provided. The X-ray machine includes a controllable X-ray generator, a digital camera and a control unit. The digital camera produces a digital visible-light image the same as the maximum irradiation range of the X-ray generator. A narrowed image portion within the digital image can be selected by the control unit. The control unit generates control signals corresponding to the selected image portion. The X-ray generator emits X-rays onto an object portion corresponding to the selected image portion based on the control signals.

A see-through display apparatus includes a first substrate having a plurality of first electrodes on its upper surface, a second substrate having a plurality of second electrodes on its bottom surface. The first electrodes and the second electrodes are alternative arrangement so that a plurality of crossing areas is formed. Each crossing area forms a pixel area and has at least one electric-excited area thereon. The electric-excited areas are alternated with the transparent areas and the see-through rate of the pixel area is ranged in a predetermined range so that the display apparatus has a see-through property.
