Abstract: The present invention relates to a method for creating a pattern on a workpiece with better pattern fidelity and dimensional precision. The method comprises the steps of: providing a source for emitting electromagnetic radiation, illuminating by said radiation a spatial light modulator (SLM) having a multitude of pixels, projecting an image of the modulator on the workpiece, moving said workpiece and/or projection system relative to each other, reading from an information storage device a digital description of the pattern to be written, extracting from the pattern description a sequence of partial patterns, converting said partial patterns to modulator signals, and feeding said signals to the modulator, further coordinating the workpiece, the modulator and the radiation source, so that said pattern is stitched together from the partial images, further exposing said pattern in at least two separate exposures, where at one exposure corrections are applied for errors occurring during another exposure.

Abstract: An electrophoretic printing method comprises layering a back electrode and a dispersion system containing electrophoretic particles on a printing substrate to form a printing layer; and providing a printing head separately from the printing substrate. The printing head has a front electrode which is a counterpart of the back electrode and which has a predetermined printing pattern. The front electrode is brought into contact with the printing layer formed on the printing substrate to oppose the back electrode. Voltage is applied between the front electrode and the back electrode so as to change a distribution of the electrophoretic particles according to the polarity of the voltage and to form a desired image on the dispersion system.

Abstract: A capacitor microphone includes a case having an end wall defining an opening for a sound hole, a capacitor portion comprising a diaphragm, a back plate and a spacer, the diaphragm opposing to the back plate via the spacer, the capacitor portion being accommodated in the case in such an manner as the diaphragm is placed on the side of the end wall, and a substrate accommodated in the case farther from the end wall than the capacitor portion, the substrate having an impedance conversion element mounted on a surface thereof facing the capacitor portion. A communicating opening is provided around the back plate in a position opposing to the impedance conversion element for communicating spaces on the front and back sides of the back plate. The communicating opening has a larger area than that of the top of the impedance conversion element to allow the spaces on both sides of the back plate to communicate with each other.

Abstract: The present invention relates to an apparatus for creating a pattern on a workpiece sensitive to radiation, such as a photomask, a display panel or a microoptical device. The apparatus comprises a radiation source, a spatial modulator (SLM) having a multitude of modulating elements (pixels), a projection system, an electronic data processing and delivery system controlling the modulator and a precision mechanical system for moving said workpiece. Specifically, the pixels could be set in a number of states larger than two, and the electronic processing system is adapted to create one type of pixel map inside pattern features, another type of pixel map outside features, and intermediate pixel maps at a boundary. The intermediate pixel map is generated in dependence on the placement of the boundary in a grid finer than that of the pixels of the SLM projected on the workpiece.

Abstract: The movement position of the roughing tool is calculated, in S109, by adding the finishing allowance to the movement position of the finishing tool so that the path of the roughing tool is shifted in the direction perpendicular to the rotation center axis of the main spindle rotation motor from the path of the finishing tool by the finishing allowance. Then, a gap between the movement position of the roughing tool in the direction of the rotation center axis of the main spindle rotation motor and the workpiece W is calculated, and when the gap is not larger than a predetermined value G, in S113, the movement position of the roughing tool is corrected in the direction perpendicular to the rotation center axis of the main spindle rotation motor so that the roughing tool does not cut in the inside of the finishing portion of the workpiece.

Abstract: A control apparatus for an automatic lathe includes a numerical controller, and comprises an input device, a readout section, and a machining program storage section. The input device inputs a machining program expressed by a predetermined language. The readout section reads out the machining program from the input device and digitizes it. The machining program storage section stores the digitized machining program into a timing table form in the order of execution. From the machining program storage section, various kinds of data such as the positional data of tools stated in the stored machining program, rotational data and movement data of a workpiece, and the like are sent out to an editing section. In the editing section, these various kinds of data are reedited and stored by a movement data editing portion.

Abstract: An insulating bushing of an electret condenser microphone is disposed on the rear side of a back electrode portion and abuts against the rear surface of back electrode plate. When a predetermined force is applied to the insulating bushing from the opened end of the case by way of a fixing ring and a printed circuit board, the insulating bushing deforms so as to fit into a gap formed between the inner peripheral face of the case and an end portion of the back electrode plate. Since the insulating bushing fits between the inner peripheral face of the case and the end portion of the back electrode plate, the back electrode plate is positioned and fixed with respect to the case in a state where the back electrode plate and the case are electrically insulated from each other.
