Abstract: For aligning the print nozzles of an ink jet printer head (DK), a defined line pattern (SCI) is printed on the recording carrier (P) for each print nozzle (D1 to D32) during a bidirectional printer advance, and is then scanned by a sensor (AB) during a scanning run. The scanned values (AW) which represent the "actual" position of the ink droplets are compared in the central control unit (ZS) of the ink jet printer with the "nominal" position determined by the drive pulses in the print column pattern (DSR), and a so-called droplet offset (VS) is determined. The droplet offset (VS), that is to say the difference determined, is stored for each individual print nozzle (D1 to D32) separately for both directions of printing (L,R), and in normal printing operation, a correction in accordance with the offset (VS) stored in the memory (VPS) is made for each print nozzle (D1 to D32). <IMAGE>

Abstract: A microwave ovenable package (10) including a layer (18) of material that will convert a portion of the microwave energy to heat and a layer (16) of paperboard interposed between the energy-converting layer and the food in the package which is to be cooked and browned. The energy-converting layer may be carried on a plastic film (20), the latter being adhered to the side of the paperboard layerwhich does not contact the food. An additional layer of paperboard (26) may be used to sandwich the energy-converting layer and the plastic film between layers of paperboard. The heat from the energy-converting layer provides a surface heating effect on the food such as browning, crisping, or singeing. The presence of the paperboard layer between the energy-converting layer and the food prevents contamination of the food which might otherwise occur due to the degredation of the plastic in those cases where the microwave cooking causes the energy-converting layer to reach a temperature higher than intended.

Abstract: A drilling system comprises a drill string (1) incorporating inbuilt tubular conductors (25), a mud supply passage, and passages for protective or other fluids. The drill string can be advanced by selectively actuable pistons (51,60) exposed to drilling mud flow, by electrically driven traction units (71,74) engaging the drill hole wall or by a linear electric motor element (82) co-operating with a drill hole casing (24), which can be moved thereby relative to the drill string. The drill bit (106) of the drill unit is driven rotatably by an electric motor (111,112) or reciprocably by a linear electric motor (125). The drill unit can be of two relatively slidable parts, with fluid pressure, which may be generated within the unit (189) axially loading the drill bit. Drilling forms can be resisted by clamps (129) clamping the unit and/or the drill string to the drill hole wall. The drilling direction can be adjusted by means of these clamps.

Abstract: A touch panel has panel scanning signals selectively applied to the four sides of a touch sensing surface of the panel so as to establish alternating current voltage gradients in desired directions across the touch sensing surface. When the panel is touched, touch signals or currents result and are utilized by a touch location circuit in determining the location of touch. The impedance touch current resulting from a user's touch may also be determined and used. The touch panel circuit automatically compensates for changes in impedance touch current, such as result when users touch the panel with ungloved and gloved fingers. An analog multiplier is included in the touch location circuit to improve noise rejection. Auto nulling and automatic frequency adjustment is included in the touch panel device, together with overcurrent protection circuitry.

Abstract: An apparatus is disclosed that is intended for manufacturing a hollow body. The hollow body has a head piece formed by blow-molding a preform segment. The apparatus includes a ring-shaped nozzle, a withdrawal device, and blow-mold pieces which are laterally, reciprocally movable. Regions of the hollow body are fabricated to have outer diameters which are less than the diameter of the extruded tubular segment before the segment is blow-molded. This is achieved by a reciprocally movable mandrel with a molding extension. The molding extension extends both radially and inwardly between projecting regions of the closed blow-mold pieces. The projecting regions of the blow-mold pieces press the corresponding parts of the preform segment against the molding extension, wherewith the ring-shaped nozzle opening is radially, outwardly offset with respect to the outer contour of the molding extension. Following the extrusion, the molding extension is advanced downward, in the embodiment illustrated, and serves as an implement for forming the inner shape of the reduced-diameter region or regions of the body part, and as an opposing thrust element for the blow-mold pieces which press together a region or regions of the tubular preform segment.

Abstract: In a semiconductor memory device, an output of a sense amplifier circuit and a reference voltage of a reference voltage producing circuit are compared to decide whether a content of a selected memory cell is "1"or "0". A load characteristic of a load circuit of the reference voltage producing circuit is different from that of the sense amplifier circuit, so that current flowing through a reference field effect transistor can be increased to a level of current flowing through a memory cell in which"0" is stored. Therefore, a time in which an output voltage of the reference voltage producing circuit is lowered from a voltage set at the stand-by mode to the reference voltage set at the reading mode is shortened at the reading mode subsequent to the stand-by mode.
