Abstract: An acoustic ink printer (10) comprises a pool of liquid ink (14) having a free surface in intimate contact with the inner face of a perforated membrane (32). The printer (10) addresses all pixel positions within its image field  via  substantially-uniform, relatively large diameter apertures (33) which extend through the membrane (32) on centers that are aligned with respective ones of the pixel positions. In operation, one or more focused acoustic beams (16) selectively eject individual droplets of ink from the ink menisci that extend across the apertures (33). Accordingly, the membrane (32) is positioned, and the bias pressure applied (14) to the ink is selected, so that the menisci essentially remain within the focal plane of such beam or beams (16).

The system uses differential surface coils (110) as the surface coils (110). A magnetic res­onance signal is detected through the homogeneous coil (109) within the same time interval in which magnetic resonance signals are detected through the surface coils (110). Weighting functions for weighting/adding pro­cessing of image data are determined on the basis of these magnetic resonance signals.

Abstract: A data processing system having an instruction execution circuit 16 that executes a first type of instruction. Also included is a fetch circuit that fetches instructions from a memory 10 and fetches data from the memory in response to a second type of instruction. An instruction decoder is included that decodes fetched instructions and dispatches instructions of the first type to an instruction queueing circuit. The instruction decoder further dispatches instructions of the second type to the fetching circuit. The instruction queueing circuit includes the capability to store decoded instructions of the first type in a queue 30 while tagging these instructions when data required for the execution of these instructions has not been fetched. The instruction queueing circuit further clears these tags of these instructions of the first type when data that is required for the execution has been fetched. The instruction queueing circuit serially provides the untagged instructions of the first type to the instruction execution circuit.

Abstract: A hydraulic injection molding machine incorporates a pump (26) driven by a variable speed motor (34) preferably of the brushless DC type. The machine controller (15) outputs driving signals to adjust the speed of the motor so that the flow delivered by the pump substantially matches the hydraulic demand imposed during each phase of the machine operating cycle. The pump is preferably a variable displacement type and is connected to a fast responding pump control (43) for selectively carrying out pressure compensation or flow compensation. The values of the motor driving signals are calculated so that the motor/pump combination is operated at or near maximum efficiency except when the pump control (43) varies the displacement of the pump to effect pressure or flow compensation. Hydraulic transient response is further improved by connecting the output of the pump to an accumulator (48) by way of a check valve (49).

Abstract: A method and apparatus for providing compensation for offset error in a numerical control unit, particularly a lathe, on the basis of tool nose height. Machine commands for one-block movement of a tool are modified by stored tool offset information (9) to produce corrected one-block travel parameters. Command data is generated by interpolating the parameter data for a single block and adjusting the command data for tool movement on the basis of stored nose height information (11) for the tool. The adjustment to the command data may take place continuously or may be implemented per block.

Abstract: In an installation for electrostatically coating workpieces with electrically conductive coating material, an earthed supply system (1) and an intermediate container (B) to which a high voltage is constantly applied and which is connected to a spray device are continuously insulated from one another by a further intermediate container (A). The insulation distances between the insulating intermediate container (A) and the earthed supply system or the intermediate container (B) to which high voltage is supplied are smaller than the flash-over width of the applied high voltage, which is possible by virtue of the fact that after the respective intermediate containers (A, B) are filled, insulating shells are rotated into the respective distances. <IMAGE>

Abstract: An electric power supply system is provided for an automatic water discharge device for discharging water to flush the basin. An object detector detects a person before the basin. A brightness detector, which consumes less electric power than the object detector, detects a brightness surrounding the basin. An electric power is supplied to the object detector on a power supply cycle so as to intermittently render it operative and to the brightness detector on a brightness detect cycle. The brightness detect cycle is longer than the power supply cycle. After a set time period following disappearance of a person from the basin, the electric power is, on one hand, shut off from the object detector to render it inoperative and, on the other hand, supplied to the brightness detector on the brightness detect cycle immediately after the shut off of electric power to the object detector, to detect a brightness surrounding the basin. When the brightness detector detects a brightness higher than a predetermined brightness, the supply of electric power is resumed on the power supply cycle for the object detector.
