A spare tire carrier for a vehicle may structurally entail a base, a mounting flange extending from the base, a vertical support post extending from the base, a light support post attached to the vertical support post, a threaded stud that engages a front surface of the base to support a spare tire. A tether, which may be secured to the base with a fastener, may lie largely concealed within the base and have additional studs or bolts which may protrude through a front surface of the base and further support a spare tire. A plurality of strength ribs may join the mounting flange and the base, while the base, the first mounting flange, vertical support post extending from the base, and plurality of strength ribs may be a single cast magnesium part. The tether may be of another high strength material.

A method for spinning a wafer to enable rinsing and drying is provided. The method includes engaging the wafer at a wafer processing plane and spinning the wafer. The method further includes moving a wafer backside plate from a first position to a second position as spinning of the wafer proceeds to an optimum spinning speed. The second position defines a reduced gap between an under surface of the wafer and a top surface of the wafer backside plate. The method also includes repositioning the wafer backside plate from the second position to the first position as the spinning reduces in speed. The first position defines an enlarged gap to enable loading and unloading of the wafer from the engaged position.

An apparatus for preparing a wafer is provided. The apparatus includes a wafer backside plate and a central shaft. The wafer backside plate has a top surface that includes a cylindrical edge lip, which defines a central aperture. The central shaft is designed to fit within the central aperture. The wafer backside plate is designed to automatically slide between an up position during rotational wager processing and a down position when the wafer is not in rotational wafer processing. A gap defined between the top surface of the wafer backside plate and the wafer is less when the wafer backside plate is in the up position than when the wafer backside plate is in the down position.

A chuck assembly for use in a substrate spin, rinse, and dry (SRD) module is provided. The chuck assembly includes a wedge, a chuck body, and a plurality of grippers. The wedge has a sidewall and is designed to move from a lower position to an upper position and from the upper position to the lower position thus opening and closing the chuck assembly, respectively. The chuck body has a cylindrical shape and is designed to include a plurality of linkage arms. The chuck body is designed to enclose the wedge such that each linkage arm is substantially in contact with the sidewall of the wedge. The cylindrical shape of the chuck body is designed to reduce air disturbance around a surface of a substrate. The plurality of grippers are designed to be coupled to the chuck body via a plurality of rotation pins. Each of the grippers is configured to stand substantially upright so as to engage the substrate when the wedge is in a lower position, and each of the grippers is configured to lie substantially flat so as to disengage the substrate when the wedge is in the lower position.

Methods and systems of pari-mutuel wagering are disclosed to facilitate the wager construction process. In one method, patrons select runners, and betting options of selected runners are presented. In another method, a first wager is placed and other wagers are presented, wherein the additional wagers may include a runner of the first wager. Another method allows patrons to wager on a runner, wherein an area representing the runner is marked to indicate that this runner was selected on a previous wager or in the current wager. In another method, a portion of a wager is patron selected and a portion of the wager is suggested by the betting interface. In another method, patrons may construct wager(s) for single or future races, or specify criteria for those wagers. In another method, runners are displayed in a table and patrons may select or deselect runner combinations by selecting cells within the table. Methods and systems of pari-mutuel wagering that enable an organization to set rules to display the gaming activity, and an embodiment where players make subscription as well as programmed bets are described.
摘要:
A load transport device that mounts to a vehicle mounted trailer hitch. The load transport system comprises a channel portion fitted with a pinion gear, and the channel portion is rigidly attached to a mounting bar that slideably engages a receiver portion of a vehicle's trailer hitch. The device also comprises an invertible shaft with an optionally-motorized rack gear system. The invertible shaft has a channel portion insertion end and a load lifting end. The invertible shaft slideably engages in either a load-low or load-high orientation depending on which end, the insertion end or the load lifting end first engages with the channel portion. The pinion gear and the rack gear system are functionally engaged. The load transport device further comprises a load support member attached to the load lifting end and comprising one or more bars that support a load.

A fluid delivery module for use in preparing a substrate is provided. The fluid delivery module includes a process bowl designed to contain a substrate to be prepared. The process bowl has a bottom wall and a sidewall. The fluid delivery module further includes a fluid delivery ring configured to be attached to the sidewall of the process bowl. The fluid delivery ring includes a plurality of inlet and outlet pairs. Each of the plurality of inlet and outlet pairs is defined in the fluid ring and is designed to receive a respective supply tube. Each respective supply tube has an end that terminates at each of the outlets of the fluid delivery ring and is configured to direct fluid onto a surface of the substrate.
摘要:
A live attenuated human immunodeficiency virus type 1 (HIV-1) whose replication is not constitutive but is instead conditionally regulated (such that rounds of reverse transcription with accompanying potential for error are strictly limited) might yield a paradigm that minimizes evolution to virulence and facilitate vaccine development. We have broached the concept of conditional control of HIV-1 through gain-of-function. Here, we describe the design of constitutively inactive HIV-1 genomes (HIV-DoxT and HIV-DoxSp) which can be conditionally resuscitated to an active state by tetracycline or related analogues. The HIV-DoxT construct comprises an inactivating mutation engineered into TAR, thereby rendering the virus non-responsive to Tat, a 302-bp DNA fragment (TetopT) which contains the tet-operator ligated into a position upstream of the HIV TATAA box, in both the 5′ and 3′ LTRs, and a reverse tetracycline-controlled activator (RTTA) coding sequence in place of the nef coding region. The HIV-DoxSp construct contains three additional Sp1 sites in the TetopT promoter upstream of the TATAA box thereby generating the promoter TetopSp. Genotypically, HIVDoxT is tat(+)tar(−)nef(−)Sp1(−) and HIVDoxSp is tat(+)tar(−)nef(−)Sp1(+). Since both genomes are genetically tar(−), they would ordinarily be expected to be wholly defective in producing viral proteins and/or particles. However, following transfection into an appropriate cell target, both proviruses, in a doxycycline-dependent fashion, capably released Gag and RT from cells. In the absence of doxycycline, no replication competent virus could be recovered. These findings suggest that the heterologous RTTA+Dox mechanism substituted effectively for Tat/TAR. These constructs should prove useful in the development of HIV-specific immunological and diagnostic reagents.
