These reactions include nucleic acid hybridization, antibody/a ntigen reaction, diagnostics, and biopolymer synthesis. The device can be fabricat ed using both microlithographic and micro-machining tech niques. The device can electronically control the transport and attachment of specif ic binding entities to specific micro-locations. The sp ecific binding entities include molecular biological molecules such as nucleic acids and po lypeptides. The device can subsequently control the tra nsport and reaction of analytes or reactants at the addressed specific micro-locations. The device is able to concentrate analytes and reactan ts, remove non-specifically bound molecules, provide stringency control for DNA hybridi zation reactions, and improve the detection of analytes. The device can be electronically replicated.

Abstract: A high-speed data register (11) for storing a series of data values received at a high-speed clock rate (RCCK) and including a first set of pipelined latches (17, 19, 21) and a second set of pipelined latches (23, 25, 27). Control circuitry (29) loads the received data values alternately into said first set of latches (17, 19, 21) and said second set of latches (23, 25, 27) from an input or "last" register (13), which stores the last data value received by the data register (11).

Abstract: A CNC lathe (1) has a control device (4) for enabling manual operation of carriages (5, 6) which are movable in mutually orthogonal directions. During manual operation, the control device (4) and the longitudinally moving carriage (5) are moved in tandem. However, for safety reasons, the control device (4) may be disengaged from the carriage (5) such that rapid movement of the carriages under the control of a CNC unit (22) is possible. The control device (4) has rollers (24) disposed in guideways (8) carried by a fixed support (7) screwed to the lathe bed (35). The fixed support (7) may similarly carry guideways (27) for slideably supporting movable covers (3). A lever (11 ) selectively engages or disengages the control device (4) and the carriage (5). Upon engagement of the control device (4) and the carriage (5), an inductive proximity switch (17) is actuated to prevent rapid traverse of the carriages.     (See fig III)

Abstract: When a picture print is generated by editing a picture image recorded on a film, the print in accordance with a customer's requirements is generated by simple operations and at a low cost. Low resolution image data of a picture image read from a film are recorded in a recording medium, in addition to software for image editing, and provided to a customer so that the customer can carry out editing operations on the picture using a personal computer or the like. When a print is ordered, editing instruction information generated by recording the operations the customer has carried out for the editing is received from the customer via the recording medium. Based on the editing instruction information, a scanner reads a film in high resolution and a printer outputs a print after automatic editing on the image data.

Abstract: A cabling media which is suitable for data transmission with relatively low crosstalk includes a plurality of metallic conductors-pairs, each pair including two plastic insulated metallic conductors which are twisted together. The characterization of the twisting is important and relates to parameters such as twist length as well as core strand length/lay. More specifically, particular combinations of twist lengths and core strand length/lay are purposely selected for each insulated pair of the cable in order to achieve performance capabilities that significantly surpass those required under TIA/EIA-568A. In one particular embodiment of this invention, a cable comprises as its transmission media, four twisted pair of individually insulatedconductors with each of the insulated conductors including a metallic conductor and an insulation cover which encloses the metallic conductor. The twisting together of the conductors of each pair is characterized as specifically set out herein and the plurality of transmission media are enclosed in a sheath system which in a most simplistic embodiment may be a single jacket made of a plastic material. As a result of the particular twist scheme employed for the conductor pairs, operational performance of the resulting cable is improved. Also, the cable of this invention is relatively easy to connect and is relatively easy to manufacture and install.
