摘要:
The invention provides isolated nucleic acids molecules, designated DHDR nucleic acid molecules, which encode novel DHDR-related dehydrogenase molecules. The invention also provides antisense nucleic acid molecules, recombinant expression vectors containing DHDR nucleic acid molecules, host cells into which the expression vectors have been introduced, and nonhuman transgenic animals in which a DHDR gene has been introduced or disrupted. The invention still further provides isolated DHDR proteins, fusion proteins, antigenic peptides and anti-DHDR antibodies. Diagnostic methods utilizing compositions of the invention are also provided.
摘要:
A device and method for moving media sheets within an image forming apparatus. The device includes a motor; a pick mechanism operatively connected to the motor, a first gear set having a first ratio and operatively connecting the motor to the pick mechanism, a feed nip operatively connected to the motor to receive the media sheet and forward the media sheet along a media path, and a second gear set having a second gear ratio and operatively connecting the motor to the feed nip. The motor may operate at a constant speed and drive the pick mechanism at a first speed and the feed nip at a second speed. The first and second speeds may be the same, or the speeds may be different.
摘要:
A classifier for classifying particulates entrained in a flowing stream of gas is configured such that a change of direction of gas flow causes particles to impinge upon a target, heavier particles being trapped in a downwardly extending fluidized trap. The classifier is easily constructed, has no moving parts, and can take the place of sifters and other equipment traditionally used for classifying such product streams.

An apparatus and method for ink-jet printing onto an intermediate drum in a helical pattern while correcting for image skew and aliasing. A plurality of ink-jet print heads place an image on an intermediate drum, impervious to ink, in a helical patter. To compensate for helical printing, the image is altered by nozzle placement and image manipulation to correct for skewing errors, and thereafter, the nozzle timing is adjusted to correct for aliasing. The plurality of print heads move parallel to the axis of rotation of the drum while the drum is simultaneously rotating, causing the image to be placed in a helical pattern. Once the entire image is placed on the drum, paper is rolled against the drum under pressure and the image is transferred thereto.

A printed circuit biopotential sensing device is provided which is particularly adapted for endocardial or other deep body applications. The device has a predetermined printed circuit pattern formed on a thin film substrate, the pattern having at least one electrode pad at its distal end, at least one terminal pad at the proximal end, and conductor means selectively interconnecting the electrode pads and terminal pads. The substrate is secured to, and is preferably wrapped around an elongated member which is preferably tube-shaped in a manner such that the electrodes are exposed at the distal end of the member, and the terminal pads at the proximal end of the substrate are utilized in forming a suitable connector from the device. By forming the conductors on only a selected fraction of the width of the substrate and overlapping the portion of the substrate containing the conductors during the helical wrapping process, the substrate insulates and protects the conductors and eliminates the need for a separate protective layer. The device may, for example, be a percutaneous catheter with the electrodes being formed at the distal end thereof, or may be a sensing probe which includes a sensing support member, such as a solid plastic member or a balloon which has the distal end of the substrate containing the electrode pads secured thereto.
