  • Patent number: 6545352
    Abstract: Methods and apparatus for mounting a semiconductor to a heat sink. A clamp is provided comprising a spring beam mounted to a clamp body, wherein the body restricts the spring beam ends and the spring beam has a convex curvature relative to an adjacent power semiconductive module. The portion of the spring beam near its apex contacts the module, applying force to bias a heat-transmitting surface of the module against a heat sink. When temperature increases, the spring beam expands to add additional clamping force to the module. Further embodiments provide making the spring beam from a material having a high coefficient of thermal expansion and the clamp body from a material having a low coefficient of thermal expansion, further increasing the force that may be applied by the spring beam with increases in temperature. The spring beam may comprise layers of different materials to increase the applied force.

  • Patent number: 6109479
    Abstract: A device for dispensing liquid medicaments in a spray form includes a container for liquid to be dispensed, an outlet nozzle which breaks up a flow of liquid under pressure into a spray, a piston for forcing liquid out of the container under pressure and through the nozzle, and a drive for moving the piston a predetermined distance to dispense a predetermined quantity of liquid from the container. A cap fits over the outlet nozzle when the device is not in use, and interengaging elements are provided on the cap and the drive to allow rotation of the drive by the cap during use of the device.

  • Patent number: 5898412
    Abstract: An indoor/outdoor antenna mounting enclosure that may be mounted either vertically or horizontally comprises a front shell and a rear shell fastened together to enclose an interior space for a printed circuit board, the shells each have a plurality of cooling fins oriented obliquely to a longitudinal axis of the enclosure. Each of the front and rear shells includes mounting bosses for two receive antennas and a transmit antenna, the transmit antenna mounting location separated by a predetermined longitudinal distance from the first and second receive antenna mounting locations. The mounting bosses allow the antennas to be oriented either with the longitudinal or transverse axis of the enclosure. Keying holes in the shells ensure that the receive and transmit antennas are mountable only in the designated mounting location in the correct orientation.

  • Patent number: 5634930
    Abstract: A hemostatic clip applicator system which is particularly useful for endoscopic procedures. A hemostatic clip applicator can be directly connected to a trigger assembly or indirectly connected to the trigger assembly through the use of an extension. The connection between the extension and the clip applicator is secured to prevent accidental release during the procedure. The applicator receives a longitudinal input and translates the input into relative component motion through the use of gearing to apply the clips.

  • Patent number: 5330487
    Abstract: A surgical instrument for applying a ligating device to a surgical work site. The instrument is provided with a power subassembly which provides the power by which the ligating device is placed into proper position for being applied to the work site. In one embodiment, the instrument is a hemostatic clip applier and the power subassembly feeds the clips into position between the jaws of the applier which are then closed by squeezing the applier handles.

  • Patent number: 5251801
    Abstract: A hand-held surgical stapler is provided having a reduced distal profile due to a unique feeding means. A combination of features allows the reduced distal profile. The staple storage cover can be of reduced distal thickness due to the slope effect. The staple pusher has the capability at its distal end to push and by pushing lift all of the staples, including the last, into the staple track. Provisions are made on the staple pusher to allow the form tool to displace it out of the staple track to allow forming of the last staple. Nose assemblies are disclosed which can be interchangeably mounted to various trigger assemblies. The pre-load on the stored staples can be varied. A ratchet feature requires full depression of the trigger before it can be returned to a neutral or extended position and full extension of the trigger to its neutral position prior to initiation of the next staple feed cycle.
