摘要： The present invention relates to a process for the production of three-dimensional articles by stereolithography using a radiation-curable composition comprising a mixture of at least one cationically polymerizable compound and/or at least one free radical polymerizable compound, at least one filler material and at least one photoinitiator for cationic and/or radical polymerization. An organic viscosity stabilizer material may be brought into contact with the composition to substantially delay or prevent undesirable viscosity increase and subsequently premature polymerization. A filler material is optionally added to the composition in an effective amount to at least delay or prevent a significant increase in viscosity and polymerization. The process is particularly suitable for stabilizing resins in stereolithography baths. The present invention also relates to a cured articles resulting from said process and a process for manufacturing said radiation-curable compositions and stabilized compositions resulting therefrom.

摘要： Pipelined image data transfer which tessellates and quads the data while transferring. The output data from the transfer can be selectively in quad or linear format. Such tessellating and formatting is performed in-line using alternate buffers for pipelining so that there is effectively no delay for performing the operations. The operations are performed by unique input and output buffer and image storage addressing.

摘要： Bus master for use in computer system includes logic for determining the number of words remaining to be transferred in a DMA operation to supply signals to permit arbitration to start for the next DMA request, thereby avoiding an idle cycle. A timeout state machine is also included to prevent the bus master state machine from hanging in a state with no exit. Errors can be masked to permit analysis of system problems.

摘要： A method and apparatus for data transmission transmits both compressed and noncompressed data over each of a plurality of transmission paths. A data identification pattern is used to request a type of data from a memory having a plurality of data types stored within it. A handshaking control module is provided to select the correct type of data from the memory and place it on the output of the memory. The requested data type is then transmitted to a data decompression module via an interface. The data transmission can occur on any one of a plurality of data transmission paths when the data being transmitted is either Linework or Linework control data. When the data decompression module receives the data, it is then routed to any one of a plurality of data decompression systems based upon the results of the evaluation of the data identification pattern. The routing of the received data is wholly dependent upon the data identification pattern and independent of which transmission path the data was received on.

摘要： A device to turn on a disk formatter's write gate and NRZ line drivers with minimal delay from a sector pulse. The device utilizes a look-ahead scheme to asynchronously qualify a sector pulse to drive the write gate and enable the NRZ output drivers. The write gate and NRZ line drivers are conditionally enabled by a sector pulse and are held in the enabled state until the disk formatter provides an enable signal. The enabled NRZ line drivers provide binary zeros until actual data is provided to the drivers.

摘要： A character generator with multidirectional scan and variable line and character (or symbol) size capability is disclosed. Universality is implemented by producing a serial binary stream which can be used to print or display in any of eight combinations of scan direction and progression, that is, for scan direction left to right, or vice versa, progressing up or down, or scan direction top or bottom or vice versa, progressing left or right. In formatting the serial binary stream, a font is accessed (for basic symbol definition), which selectively provides for orthogonal scan of the symbol definitions. Variable line size is implemented by terminating a symbol row (or line) based on a predetermined size criteria regardless of the comparable font dimension and "filling" up to the line size to the extent the corresponding font dimension is less than the predetermined size criteria. Variable character (or symbol) size is implemented by independently multiplying the effect of a symbol definition by selected (integral) factors, in orthogonal directions. The general architecture includes a font table (for symbol definition), an address/escape (A/E) table, defining symbol size for comparison with line size parameters, a character position escape (CPE) table to define a leading character or symbol on each line and a page buffer (PB) memory defining the characters (symbols) in the document and their relationship with other characters (symbols). Access to the CPE table allows access to the PB, from there to the A/E table and from there to the font allows extraction of selected and appropriate portions of the symbol definition to make up the binary system.
摘要翻译：公开了具有多向扫描和可变行和字符（或符号）大小能力的字符发生器。普遍性通过产生串行二进制流来实现，该串行二进制流可用于以扫描方向和进展的八种组合中的任何一种来打印或显示，即扫描方向从左到右，反之亦然，向上或向下或扫描方向顶部或底部，反之亦然，向左或向右前进。在格式化串行二进制流时，访问字体（用于基本符号定义），其选择性地提供符号定义的正交扫描。可变线尺寸通过基于预定尺寸标准终止符号行（或线）而实现，而不管可比较的字体尺寸如何，并且在相应的字体尺寸小于预定尺寸标准的范围内“填充”直到线尺寸。通过在正交方向上独立地将符号定义的效果乘以所选（积分）因子来实现可变字符（或符号）大小。一般架构包括字体表（用于符号定义），地址/转义（A / E）表，定义用于与行大小参数进行比较的符号大小，用于定义前导字符或符号的字符位置转义（CPE）表每个行和页面缓冲区（PB）存储器定义文档中的字符（符号）及其与其他字符（符号）的关系。访问CPE表允许访问PB，从那里到A / E表，从那里到字体允许提取符号定义的选定和适当的部分，以构成二进制系统。
