Abstract: The present invention provides for a negative acting photoresist composition exhibiting excellent contrast and sensitivity in the broad band and deep UV band of the spectrum comprising a mixture of an alkali soluble polymeric binder material, a photoinitiator and a photopolymerizable compound containing at least two terminal ethylenically unsaturated groups. The polymeric binder material is essentially free of ethylenic unsaturation or other substituent groups which will react with the photopolymerizable compound when exposed to light in the presence of the photoinitiator. The composition of this invention when formed into a film provides negative photoresist coatings which cure rapidly under exposure to actinic radiation to form an insoluble, interpenetrating resinous network in the exposed areas but which are stable and retain their solubility in alkaline developers in unexposed areas.

Abstract: An emitter follower output circuit (11) includes a first bipolar transistor (Q₃) for outputting a potential from its emitter to an output terminal (10) and a second bipolar transistor (Q₄), connected in series to the first bipolar transistor, for feeding a current to the first bipolar transistor. A capacitor (C) connected between a collector of the first bipolar transistor and a base of the second bipolar transistor detects a transitional change of a potential at the collector of the first bipolar transistor and controls a potential at the base of the second bipolar transistor. The current flowing into the emitter follower output circuit is made small independently of the potential level of the output terminal in the steady-states, the current is made large transitionally and correspondingly to the degree of the load capacitance so as to discharge the load capacitance rapidly in the falling period of the output signal, and the current is made small transitionally so as to charge the load capacitance rapidly by use of the output transistor, whereby it is possible to provide an emitter follower output circuit which consumes little power and which oparates at a high speed.

Abstract: According to a method and apparatus for recognizing meandering of a web, all pixel addresses and all pixel data of printed matter serving as a reference are received and it is determined whether each pixel represents a region in which an abrupt change in density occurs as an edge. The pixel address and pixel data of each pixel determined as an edge are stored as the reference image data. A difference value between pixel data of test image data obtained from the web on which a test object is printed and pixel data of the reference data at the pixel addresses of the reference data and the corresponding pixel addresses of the test image data in a one-to-one correspondence is calculated. A meandering state of the web is recognized on the basis of each difference value.

Abstract: A class of lossless data compression algorithms use a RAM-based dictionary to facilitate the compression and decompression of data. The dictionary is initialized or reset at various events, such as data file boundaries, or at specific compression ratio thresholds. The average time to perform the dictionary reset is decreased by using a dictionary reset optimizer (12) to reset the dictionary without writing the DICT_VALID fields (19) of all dictionary locations (1,2,3,..L) immediately upon each reset. The DICT_VALID field in static RAM (16) is set up as an N-bit field and the optimizer includes a counter (20) for generating an N-bit DICT_NUMBER field (22) under control of a controller (24) responsive to reset signals. During operation to compress/decompress data after a reset, the DICT_VALID field of a dictionary location is compared to the current DICT_NUMBER(1). If their values are equal, the DICT_ENTRY field (18) in such location is deemed valid. Otherwise, the DICT_ENTRY field is rewritten with new compression data and the DICT_VALID field is reset equal to the current DICT_NUMBER(1). Upon each reset, the counter is incremented to provide a new DICT_NUMBER(2) whose value will no longer match current DICT_VALID values stored in the dictionary locations.

Abstract: A call-processing arrangement (200) views a network numbering plan as a language in the mathematical/computer science sense and takes a lexicographic approach to call processing. Numbering plan syntax is defined by data in tree data structures (320, 330), and numbering plan grammar is defined by data in matrix data structures (400, 410). The data structures are used by numbering plan-independent functions to determine the meaning of call-associated digit strings and to specify the treatment (e.g., routing, features,) to be given to the call based on that meaning. A string-identification function (340) applies collected digits to the trees and matrices to find leafs (312) that define digit strings that make up the number. A string-action function (341) uses the definitions in the found leafs to form a call- route-specifying or call-feature-specifying index (254) for the call. A generalized route- selection function (343) uses a set of first call characteristics including the route-or-feature-specifying index to select from multi-dimensional matrices (1200, 1202) either a feature module (205) to be invoked or a routing-pattern number (1201), and in the latter case uses a set of second call characteristics including the routing-pattern number to select a route preference (1701) from routing pattern-preference tables (1300). A digit-sending function (344) uses the route preference to select an entry of digit-sending information (1701) from a sending table (1700) and uses the sending information to establish a call path and to outpulse digits. A digit modification function (343) and a table (1000) of digit modifications are also provided for purposes of number conversion, such as between different network numbering plans when more than one is defined.

Abstract: A method of coordinating the transmission of polling messages from a low voltage distribution substation and the responses from a plurality of electricity meters is provided. The transmissions and responses are communicated over the low voltage distribution network. Precise phase of the data bit timing of transmitted polling messages from the substation is preserved between transmissions and the response from electricity meters maintains the phase of the data bit timing of the messages from the substation in its own transmissions. A further feature of the invention is to operate a mains metering system so as to avoid interference between polled data collection systems operating from each of a plurality of interconnected substations. This is achieved by operating each of the polled data collection systems on a separate frequency. By operating a plurality of polled data collection systems each on a separate frequency the information carrying capacity of a power distribution network data transmission system is increased.

Abstract: In the television broadcasting system called letter box method, it is proposed to transmit an image having a larger aspect ratio than that of the existing broadcasting system by using some of the scanning lines of the existing broadcasting system, and transmit some additional information signal in the remaining portion. An offset value applied to the additional information signal at the transmission side must be removed completely at the reception side. Accordingly, at the reception side, in the scanning line in which an offset reference signal indicative of the offset value is transmitted, the offset reference value and a DC level reference value of the scanning line are detected, and these values are retained until a next offset reference signal is detected. By detecting a DC level of a scanning line containing the additional information signal, a difference from the DC level reference value previously detected and retained is obtained, and the offset reference value detected and retained previously is corrected by this difference. Thus obtained offset value is subtracted from the transmitted additional information signal.

Abstract: Disclosed is an apparatus which can serve to detect, count, size discriminate and analyze the chemical composition of particles in the air or process gases. In a preferred embodiment, the particles enter via a capillary (4 or 5) into a differentially pumped chamber (6). A pulsed laser (10) which is continuously fired is focused at an opening in the chamber. When the particles come into the path of the laser beam, the particles are fragmented and ionized. A dual time of flight mass spectrum is produced, recorded with an oscilloscope (16) and analyzed with a computer (22). The mass spectrum information enables the determination of the chemical nature and concentration of the species of the particles, the particle size and the elemental composition of airborne particles in real time. Once these parameters are determined the source of the particles can be determined and eliminated from the environment and process. Thus, the inventive apparatus is advantageouslyused in conjunction with a facility  i.e. , a semiconductor manufacturing facility, that requires ultra-clean conditions.
