Abstract: @ An automatic external cylindrical grinding center (10), having a pair of driven grinding wheels (86,88) capable of straight and angular wheel feed for grinding a workpiece in on-center or chucking configurations. The grinding center (10) has a base (16) with a swivel table (20) pivotally mounted thereon. A longitudinally positionable work head (24) and footstock (26) are mounted on the base (16). A carriage (56) is slidably mounted on ways (52,54) which extend longitudinally on the base (16). A pair of rearward extending ways (72, 74) are provided on top of the carriage (56) to support a wheel slide assembly (76) for back and forth movement. A rotatable wheel head (84) is mounted from the wheel slide (76) and supports two driven grinding wheels (86, 88) mounted thereon. The rotatable wheel head (84) is positionable at various positions to bring either grinding wheel (86,88) into position for contacting the workpiece. The carriage (56) and wheel slide assembly (76) are movable along their respective axes in response to a programmable controller. The orthogonal feed axes can be selectively programmed to operate independently or simultaneously at independent or related feed rates permitting use of the machine as a straight plunge or an angular feed grinding machine. A carriage traverse guide (66) extending parallel to the longitudinal ways (52,54) is located to minimize effects of machine base thermal distortions. Two fixed dressing diamonds (36,38) are mounted to the footstock (26) for dressing the grinding wheels (86,88). Dressing is accomplished by moving the carriage (56) and wheel slide assembly (76) along a selected path at programmed rates and distances to produce the desired wheel contours.

Abstract: A low loss fiber optic coupler is fabricated by forming a coupler preform having a plurality of spaced glass cores extending longitudinally through a matrix of glass having a refractive index lower than that of the cores. The coupler preform is formed by inserting a plurality of coated optical fiber preform rods (26,27,28) into an aperture (20) extending axially through an elongated boule (21) of relatively etchable matrix glass. The cladding portion (35) of the rods, which is relatively etch-resistant, is coated with a layer of etchable glass (36). The coupler preform is heated and stretched to form a glass rod (43) which is then severed into a plurality of units (45; 49). Heat is applied to the central region (66) of each unit, and the central region is elongated and tapered inwardly. When an end of the unit is immersed in acid, the matrix glass dissolves, thereby leaving the unit cores and surrounding etch-resistant cladding glass protruding from the newly formed endface of the unit.

Abstract: A manipulator (3) for moving rough castings relative to a grinding unit is provided on a grinding machine for cleaning castings. The object is to automatically feed the castings (29) to the manipulator (3) in a simple manner. For this purpose, a track consisting of two guide rails (13) is run around the manipulator (3) and is interrupted in its working space (4). Pallets (14), guided on grooved rollers (26), are moved on the track by a friction drive lying below the guide rails (13). In a work-holding fixture (31) designed as a negative cast, the pallets (14) each carry a casting (29) which is only loosely inserted. The clamping of the casting (29) for the machining is effected by the manipulator (3) in a unit with the pallet (14). For this purpose, clamping bolts (23) are provided in the pallet (14) which are used for reception in the manipulator (3), carry the grooved rollers (26) and also hold the work-holding fixture (31). The manipulator (3) pulls the clamped unit of pallet (14), work-holding fixture (31) and casting (29) off the guide rails (13) and also puts them on the guide rails (13) again after the machining. The tool change and the expansion of the system, owing to its simplicity, are possible without problem and with little expense. <IMAGE>

Abstract: This invention is directed to a process for manufacturing thermal ink jet printheads wherein a polymer barrier layer is employed between a thin film resistor (TFR) substrate and a metal nozzle plate and serves as both the ink reservoir-defining material and the adhesive bonding mechanism for firmly securing these members one to another. The polymer barrier layer material is initially U.V. cured, then partially thermally cured in a heat staker and finally completely thermally cured in an oven. The surface contour of the barrier layer follows that of the nozzle plate and TFR substrate and thereby prevents any gaps from occurring in this composite structure. This feature in turn enhances the structural integrity of the printhead, enhances its lifetime and improves its frequency response. Repeatability of manufacturing and a more consistent drop volume ejection from printhead to printhead is also achieved.

Abstract: Apparatus and method for modelling differential pulse code modulation (DPCM) input data for entropy coding. In partic­ular, the sign and magnitude of one piece of DPCM data after another are modelled to provide a magnitude state input and a sign state input to provide context for DPCM magnitude in­put and DPCM sign input, respectively, to an entropy encoder or decoder. That is, the DPCM magnitudes of earlier pieces of (context) DPCM magnitude data are re-mapped for each such earlier piece of data, the re-mapped data being aggregated to form a combined value indicative of the magnitude state input. Similarly, the DPCM signs of earlier pieces of (con­text) DPCM sign data are re-mapped for each such earlier piece of data, the re-mapped data being aggregated to form a combined value indicative of the sign state input. In an image data compression system, the magnitude state input serves as an activity indicator for picture elements (pixels) neighboring a "subject" pixel. According to the invention, the DPCM signal is derived from a difference value calculated by subtracting one of a plurality of predictor values from the graylevel value X of the subject pixel. The selection of predictor value P is based on the value of the magnitude state (activity indicator). In addition, the difference value is subject to adaptive quantization in which one of a plu­rality of quantizers is employed in assigning the (X-P) dif­ference value to a quantization level. The selection of quantizers is also based on the value of the magnitude state (activity indicator).
