Abstract: A process for forming a layer of patterned photoresist on a substrate (50), includes the steps of forming on the substrate (50) a layer of polymeric photoresist material (52), and converting selected, relatively thin regions (62) to monomeric form by utilizing depolymerizing wavelength energy. Next, the layer (52) is subject to a blanket exposure to render a thin surface layer (66) thereof opaque to depolymerizing wavelength energy. Then, using the surface layer (66) as a mask, the monomeric regions (62) are extended through the entire thickness of the photoresist layer (52), whereafter the monomeric material is developed out. A plananized, high resolution structure is thus achieved.

Abstract: According to the present invention, when image data are subjected to a quantization processing by an error diffusion method, the generation of a striped pattern which is a cause for the deterioration of picture quality in the error diffu­sion method is prevented. In the present invention, an original image is read and image data are generated. The image data obtained by reading the original image are quan­tized by an error diffusion method, and the quantized image data are output and recorded by a thermal-head printer. 
     Furthermore, according to the present invention, an er­ror between the density of an input image and the density of an output image after subjected to a quantization processing by an error diffusion method is perfectly preserved. In an image processing apparatus for performing a quantization by dispersing an error between input image data and output image data when the input image data are quantized to image data of surrounding picture elements, an error between the input image data and the output image data is operated, the operated error is subjected to a predetermined weighing processing, the error subjected to the weighing processing is dispersed to surrounding picture elements, and a surplus of the error generated at the weighing processing is cor­rected.

Abstract: In an ink jet printer (110), the time that has elapsed since the ink jet cartridge (220) last printed is timed and after one hour has elapsed with no printing, all the nozzles (222a-222b) of the cartridge are caused to print, to prevent clogging of the nozzles. Also, a line of constant average dot density along its length is plotted, regardless of the orientation of various segments making up the plotted line. For any one increment of chart movement, each point in the other dimension is plotted only once, to conserve ink and prevent heavy buildup of ink on the chart. When the printer (110) is in plot mode, the nozzles are used in sequence, instead of always using the same nozzle, so as to lengthen the life of the cartridge (220).

Abstract: The object on which the invention is based is to design a cop and tube transport system within an automatic winding machine in such a way that, even at a high production output of the ring spinning machines, a frictionless transport of the cops and tubes and an effective processing of the cops in the winding machine can be guaranteed. 
<??>The solution according to the invention provides the arrangement of two different preparatory devices in different transport loops of the automatic winding machine. The first transport loop is formed from main transport paths on which a first preparatory device is arranged. A second transport loop also includes secondary transport paths on which second preparatory devices are arranged. These second preparatory devices differ in construction and operation from the first preparatory devices. Furthermore, the arrangement on the secondary transport paths makes a considerable lengthening of the cycle times possible, thereby achieving a maximum success rate of the correct preparation of the cops.

Abstract: A circuit for operating, especially for starting, a gas-discharge lamp (GE), having a resonant circuit (L1, C1, C0) to which the lamp (GE) can be connected by means of its two heating coils or electrodes, and having an AC voltage generator (20) which emits an output AC voltage (uw) of variable frequency and/or variable duty ratio (d) to the resonant circuit (L1, C1, C0), is intended to be constructed such that a non-heated gas-discharge lamp (GE) can be started and operated more smoothly and in accordance with the regulations for explosion-protected spaces. This is achieved in that the resonant circuit (L1, C1, C0) has a first resonant frequency (f1) and a second resonant frequency (f0), below the first resonant frequency (f1), and that, in order to initiate the starting of the lamp, the main frequency component of the output AC voltage (uw) of the AC voltage generator (20) is close to the first resonant frequency (f1) and in that, after starting of the lamp (GE), the main frequency component of the output AC voltage (uw) is close to the second resonant frequency (f0). <IMAGE>

Abstract: A pretreatment process for fabricating graphite fiber epoxy composites preforms from epoxy resin. The pretreatment process comprises the step of heating an epoxy resin mixture to an elevated temperature for a period of time necessary to form a stabilized material, yet retaining a sufficient exotherm, the exotherm being necessary to lower the viscosity upon subsequent consolidation and cure. This reduces the in-press fabrication time of the stabilized material upon subsequent cure. Processes are also disclosed for the subsequent cure of the stabilized epoxy resin mixture to form an advanced graphite fiber/epoxy composite.

Abstract: A method for fabricating a diode, for example, for use in a Schottky clamped transistor, which as a process step disposes a layer of oxide (12) between the substrate (2) and the overlying layer of polysilicon (16) which must ultimately be etched away. The oxide layer permits use of an end point dry etch process which in turn allows greater miniaturization of the circuit over wet etch processes. Use of the end point process made feasible by the oxide layer also prevents overetch of the silicon material. As a result, a more ideal metal silicide (36) anode-to-substrate Schottky barrier is formed with corresponding improvements in the diode ideality factor. In addition the oxide layer eliminates Schottky mask alignment problems and further improves diode performance characteristics by elimination of parasitic diodes. The process can be implemented with minimal deviation from other core processes used to fabricate similar circuits.
