Abstract: A method of fabricating a large array or pagewidth silicon device is disclosed. The pagewidth device is assembled by abutting silicon device sub-units (20) such as image sensors or thermal ink jet printheads. For printheads, the sub-units are fully operational small printheads comprising an ink flow directing channel plate and a heating element plate (37) which are bonded together. A plurality of individual printhead sub-units are obtained by dicing aligned and bonded channel wafers and heating element wafers. The abutting edges of the printhead sub-units are diced in such a manner that the resulting kerfs have inwardly directed sides (45) which enable high tolerance linear abutment of adjacent sub-units. The wafer surface containing the heating elements may first be anisotropically etched to form small V-­grooves, one wall of which protects against microcracking during the      dicing operation. The other wall of the V-groove is obliterated by the slanted dicing blade.

The substrates have tilt orientation directions parallel to each other which are capable of orientating liquid crystal molecules homeotropically or pseudo-homeotropically at an angle range of from 0̸° to about 20̸° . The nematic liquid crystal layer has negative dielectric anisotropy and contains no or a very small amount of chiral molecules. The cell has a response time shorter than the driving frame time, and a small gap and low viscosity so that the liquid crystal layer is not twisted at an "OFF" state but is spontaneously twisted only in an "ON" state in which a pulse voltage is applied to the cell.

Abstract: A tubular sheath (10,14) for insertion into a body passage (56,60) through a reduced diameter access port and expansion to a diameter exceeding that of the access port after introduction into the passage. The sheath is fabricated of an elastomeric material and, when stretched, reduces to an outside diameter significantly less than that of the inside diameter of the body passage. An elongated stylet (38) is extended through the sheath and engaged with the distal portion adjacent the open end thereof to stretch the sheath as it is inserted into a body passage. The elastomeric construction enables an oversized object (54,58) received within the expanded end portion (14) to be drawn through portions of the sheath of a nominal diameter less than the object.

Abstract: A dot-matrix printer which operates as a line head printer and is capable of reading line head printer print data and moving head printer print data. A memory (36) stores print data. A series of clock pulses are generated and a shift register (34) reads a portion of the print data from the memory. Upon receipt of a pre-determined clock pulse (L), the shift register (34) writes the group of print data to a first latch register in a series of latch registers. The print data in each latch register is then written to a succeeding latch register. Upon receipt of a pre-determined clock pulse and in accordance with the print data, heating elements heat specific dot elements in a group of dot elements thus printing an equivalent of one print line. The print sheet is then advanced a distance equivalent to a print line comprising the group of dot elements and the process is repeated as required. The latch registers of the disclosure may be eliminated and replaced with shift registers, thus the print data is read directly by the shift registers and therefore the operating speed is increased.

The first and the second passband delay characteristics have first and second ripple amplitudes. Preferably, the first and the second ripple amplitudes are given opposite polarities. More preferably, the second ripple amplitude is substantially equal to the first ripple amplitude. It is possible to use the first and the second surface acoustic wave rolloff filter circuits either separately in the modulator and the demodulator devices or only in the modulator or the demodulator device.

Abstract: Multi-cavity injection molding apparatus to coinject pressurized melt from two or more melt sources. An inner melt passage (46) extends through the central bore of a melt distribution plate (28) and an adjacent heated nozzle (10). The nozzle (10) has a tapered nose portion (76) which extends into an adjacent heated cavity forming insert (14) having a gate (50) leading to one of the cavities. An outer melt passage (54) is separated by curved conduits on opposite faces (136, 138) of the melt distribution plate (28) into four channels (82) which are radially spaced around the central bore (78) of the nozzle. The four channels (82) lead to a melt funnel duct (98) which extends in the adjacent cavity forming insert (14) around the nose portion (76) of the nozzle (10). Thus the melt from the outer melt passage (54) is evenly distributed around the melt from the inner melt passage (46) when they join just before entering the gate (50).

Abstract: A biological sample collection tube suitable for use in collecting and processing blood samples, is of high strength, transparent plastic. The tube wall is substantially gas impermeable, permitting the retention of samples therein, under conditions of vacuum, for prolonged periods. The selected material is combustible in air, yielding products of combustion that are substantially non-toxic, to facilitate the safe disposal of the tubes, together with the enclosed samples. The tube is made of plastic copolymer or monomer resin such as polyethylene, polypropylene or polyamide. A preferred material group is amorphous nylon, in particular Nylon 6 (T.M.) such as polyethylenenaphthalate and ethylene vinyl alcohol. The tube may be made from a combination of such materials by mechanical integration in manufacture, through co-extrusion, co-injection, or by a dual material indexed molding process. The impermeability of the tube wall may be enhanced by the application of a sealing coating of polyvinyldichloride, applied to the inner and/or the outer surface of the tube wall. The tube is compatible with a wide range of inner wall coating substances, to facilitate the processing of blood samples. A sealing cap for use with the improved tube has a tapered or parallel body of a thermoplastic elastomer, one embodiment of which incorporates a safety overcap to limit the formation of an aerosol when the tube is opened.

Abstract: Fluid flow along a fluid path is determined by measuring the travel time between two transducers of two oppositely travelling acoustic burst waves. A pair of phase reference signals in phase quadrature are compared with the signals received by each transducer to determine the phase difference therebetween. The phase difference values are used to calculate the flow velocity. 
     After each phase difference determination has been made, the transducer drive signals are adjusted so that the launch time of the next pair of burst waves reduces the phase difference between the previously received signals and the phase reference to zero in the absence of any changes in flow velocity. The duration of each acoustic burst is sufficient to ensure that a predetermined number of successively received cycles in each burst are used in the phase comparison process.
