Abstract: Z-buffer control logic that provides access AND comparison at speeds unconstrained by DRAM memory access times. A Z-buffer controller is implemented which accumulates a number of pixels in adjacent locations into an associated cell. A Z-buffer comparator accesses Z-buffer retained values for the cell in parallel, performs parallel comparisons, and passes the results to a serializer. The Z-buffer serializer returns the order of the written pixels and outputs the required values to a display interface for continued processing and display on a graphics display device.

Abstract: A fractional-N type frequency synthesizer includes a frequency divider having a selectable integer divide number which is periodically temporarily altered to provide an average rational divide number for the frequency divider. A number of modulator circuits coupled in cascade fashion provide a zero sum modulation signal which varies the value of the frequency divider divisor value such that the net change in divisor value due to the modulation signal is zero thereby reducing phase noise resulting from the temporary altering of the integer divisor value close to the frequency synthesizer carrier frequency.

Abstract: An electrically conductive, semi-transparent, imaging member layer includes a polymer having carbon black particles contained therein. The polymer is obtained by dispersing carbon black particles in polymer reactants prior to and/or during polymerization of the polymer. The carbon black particles become intimately connected with other carbon black particles through polymeric chains formed when the polymer forming reactants are reacted through free radical polymerization in the presence of carbon particles. The layer can have comparable conductivity with that of dispersed carbon particles in a polymer matrix, with between 10 and 50 times less carbon black particle loading.

Abstract: A semiconductor laser diode includes a first buffer layer (14), a second buffer layer (18') and an active layer (16) sandwiched between the two buffer layers. The active layer contains dopant ions where the dopant ions are such that energy transfer between the unimplanted material in the active layer and the dopant ions implanted causes lasing action substantially at a single frequency characteristic of the dopant ions. The two buffer layers confine light emitted by the active layer. According to one aspect of the invention, the second buffer layer is grown epitaxially on the active layer. According to one aspect of the invention, the second buffer layer is grown epitaxially on the active layer. In the preferred embodiment, the structure is made by first growing a thin second buffer layer (18)_ epitaxially on the active layer. The dopant ions are then implanted into the active layer through the thin second buffer layer (18). The structure us heated to a high temperature to anneal the structure and to activate the dopants. The second buffer layer is then further grown to make it thicker so as to be more effective in confining the light emission in the active layer. According to another aspect of the invention, the dopant ions are titanium ions.

Abstract: An engine (1) is selectively operable in two- and four-cycle modes by varying the timing to open and close intake and exhaust valves (11,12) on the top of a cylinder. The engine has first and second valve actuating mechanisms (3,31,32;4,41,42) for opening and closing the intake and exhaust valves. A selective operating mechanism (6,60) operates the first valve actuating mechanism to open and close the intake and exhaust valves while the second valve actuating mechanism is disabled, and operates the second valve actuating mechanism to open and close the intake and exhaust valves while the first valve actuating mechanism is disabled. A rotation transmitting mechanism (51,52,3335,43-45) transmits the rotation of a crankshaft of the engine, each time the crankshaft makes two revolutions, to the first valve actuating mechanism through the selective operating mechanism when the engine operates in the four-cycle mode, and transmits the rotation of the crankshaft, each time the crankshaft makes one revolution, to the second valve actuating mechanism through the selective operating mechanism when the engine operates in the two-cycle mode. The rotation transmitting mechanism starts to transmit rotation of the crankshaft to the first and second valve actuating mechanism when the crankshaft has been angularly moved through a predetermined angle.

Abstract: The invention relates to a contact apparatus for manufacturing a pressed contact connection between rigid and flexible printed-circuit boards. It is necessary to manufacture a connection which is suitable for high frequencies and is gas-tight between two printed-circuit boards which are fitted with very large-scale integrated circuits. This connection must have a monitored characteristic impedance. To this end, the invention provides that the rigid printed-circuit boards (1, 2) have contact spots (7, 8), and the flexible printed-circuit boards (3) have contact fingers (11, 12, 13, 14) as contact points for the conductor tracks of the printed-circuit boards (1, 2, 3). The contact fingers (11, 12, 13, 14) of the flexible printed-circuit board (3) and the contact spots (7, 8) of the rigid printed-circuit board (1, 2) are located one on top of the other. Arranged on the rearside of the flexible printed-circuit board, which is not provided with the conductor track, there is a spring strip (26, 35) which is supported in a carrier (28, 29, 31) and whose individual springs (23, 25), which are stamped out at the same distance as the contact fingers (11, 12, 13, 14) of the flexible printed-circuit board (3) [lacuna] contact fingers (11, 12, 13, 14) and contact spots (7, 8) is pressed individually over the insulation layer of the flexible printed-circuit board with the aid of elements (32, 34) which absorb the opposing force. <IMAGE>

Abstract: A spectrophotometer apparatus (200) is adapted to provide spectral reflectance measurements of object, particularly optical characteristics of colored surfaces comprising metallic or pearlescent particles. The apparatus (200) comprises a source light and a reflection optics assembly. Signals representative of reflected light are analyzed and data is generated representative of the spectral response characteristics of the object sample. The apparatus employs a plurality of fiber optic bundles for receiving light reflected from the object sample, with each of the fiber optic bundles being positioned at one of a corresponding plurality of fixed angles different from the angle of illumination by the source light. Reflectance is measured at each angle by sequential switching such that light is impaired from being received from all but one of the plurality of multiple angles. Light received from the fiber optic bundles is transferee to a single array of integral interference-filter/photodiode devices which modulate the light and determine the spectro characteristics thereof. With the use of fiber optic devices, a single source of illumination and a single optical detector arrangement, the spectrophotometer apparatus is employed within an optimally small packaging configuration, and the apparatus can be maintained in a portable mode while maintaining relatively high accuracy and repeatability.

Abstract: In a data storage method for checksum DASD arrays, files are classified by length and/or other characteristic. Each relatively shorter file is written to an address or contiguous addresses typically on a single DASD of the array. The checksum stored on a checksum DASD is updated by reading the existing checksum, XORing that with the new data and writing the new checksum. Each relatively longer file is subdivided into portions all of the same size, and the number of equal portions is equal to the number of data DASDs where the file is to be written. The portions are interleaved in a stripe of addresses on the data DASDs, and the checksum of the portions is written to the checksum DASD. The characteristic transition length is dynamically varied in order that each interleaved file is provided with contiguous addresses matched to the file size.
