Abstract: A reciprocating pump piston includes a piston rod which is adapted to be disposed within a cylinder. A piston hub is secured to the piston rod and is adapted to be reciprocated thereby within the cylinder. The hub includes a flange portion having a cylindrical outer periphery of slightly smaller diameter than the inner diameter of the cylinder and a generally cylindrical body portion having a diameter smaller than the flange portion. An annular piston seal ring is disposed about the hub body portion. The seal ring includes an inner leg disposed in mating relation with the body portion and an outer leg defining an annular sealing lip which yields radially inward upon insertion of the hub into an associated pump cylinder. Yielding of the outer leg is to a predetermined extent sufficient to block dislodgement of the inner leg from mounted association with the hub body portion. Also provided is an annular anti-extrusion member disposed around the hub body portion intermediate the seal ring and the hub flange portion. The hub body portion includes a circumferential groove adjacent the forward end thereof, and the seal ring inner leg includes portions which closely fit into the groove.

Abstract: A pipelined instruction execution system including a micro­store (20a) for storing sequences of microinstruction addresses associated with each macroinstruction, a nano­store (20b) for randomly storing unique microinstructions, and an execution unit (30) for executing the microinstruc­tions is provided with a no-op/prefetch apparatus (50), which prevents a microinstruction address, stored in the microstore, from accessing the nanostore and forces a no-op address into the nanostore when the execution unit executes a conditional microbranch instruction. During the execution of the no-op microinstruction in the execution unit, the no-op/prefetch apparatus permits either the next sequential microinstruction address following the conditional micro­branch instruction to access the nanostore or another non-­sequential microinstruction address to access the nanostore, the selection of the next sequential microinstruction address or said another non-sequential microinstruction depending upon the outcome of the execution of the condi­tional microbranch instruction by the execution unit.

Abstract: A thin film photovoltaic module has transparent electrodes on front and back surfaces of a semiconductive layer. In one embodiment, both transparent electrodes pass light to the semiconductive layer for photovoltaic purposes. In another embodiment, the back electrode passes light which enters through the front electrode and is not absorbed by the semiconductive layer, so that the module is selectively transparent to the unabsorbed light. The spectral makeup of the transmitted light is controlled by controlling the optical characteristics of the layers of the module. The index of refraction of the back electrode is a primary source of transmission control along with the refractive index of the front electrode and the thickness of the semiconductive layer itself. Light transmitted by the module can be used for nonphotovoltaic purposes, such as illuminating the interior of a vehicle or dwelling, or may be directed back into the semiconductive layer by a reflective surface behind the back electrode.

Abstract: The invention deals with removing short-circuit­ing deposits from sputtering cathodes disposed in a sputtering chamber and normally energized from a DC power source which provides sufficient energy to produce and maintain a sputtering plasma. 
     According to the invention, a short-circuiting deposit is removed by first interrupting the power supply from the DC source (60) to the short-circuited cathode, and then applying, from an auxiliary power source (72), elec­trical energy sufficient to vaporize the short-circuiting deposit but insufficient to ignite a sputtering plasma. The auxiliary power source is disconnected and the power supply from the DC source is resumed when the short-circuiting deposit has disappeared.

Abstract: A record carrier for a data storage apparatus has an information layer (19) having tracks (11, 13) for storage of data, the tracks being so arranged and disposed to form a diffraction grating for an incident radiation beam so as to generate a push-pull signal usable as an uncorrected track following signal. The tracks are comprised of longitudinally disposed sectors, each sector having an associated header (24, 44) and associated servo areas. The storage apparatus, in operation, may produce and read detectable modulations in the record carrier by means of directing incident radiation beam to a spot (70) in the information layer (19). The spot is moveable along the longitudinal direction of one of the tracks and perpendicularly across substantially parallel tracks. The storage apparatus, in operation, reads the detectable modulations in a returned radiation beam. The record carrier has a track format in each track comprising discontinuities (41) for generating a correcting signal for correcting said push-pull signal, located in each servo area, qualifier modulations (26, 46) for producing a qualifier signal in the servo area (40) for confirming the coincidence of one of the sector headers under the spot and modulation clocking (21) comprising nonreflective timing pits.

Abstract: In an electrophotographic printer or the like, compensation is provided for environmental effects (temperature, humidity, photoconductor aging, etc.) which would otherwise affect print quality. Analyzing print data allows identification of compensation locations; those are locations at which compensation is most critical, such as single pel lines. A series of clock pulses of varying phase displacement are employed, and selected based on environmental variations, so as to modify the print data at the identified compensation locations. The print data comprises a series of pulses. Compensation to control the width of lines perpendicular to the scan direction is effected by selectively advancing the leading edge of pulses defining a white/black transition and delaying the trailing edge of pulses defining the black/white transition. This control then affects the duration of the print pulses. For lines which are parallel to the scan direction width control is effected by adding gray pulses, both the leading and trailing edges of these gray pulses are controlled in accordance with environmental variations. Accordingly, the duration of the gray pulse is also controlled.
