摘要:
A method of manufacturing a sensor for in vivo applications includes the steps of providing two wafers of an electrically insulating material. A recess is formed in the first wafer, and a capacitor plate is formed in the recess of the first wafer. A second capacitor plate is formed in a corresponding region of the second wafer, and the two wafers are affixed to one another such that the first and second capacitor plates are arranged in parallel, spaced-apart relation.

A device for use in culturing a cell is provided. The device comprises at least one cell culture chamber and a fluid reservoir. The cell culture chamber has a tapered side wall and is in fluid connection with the fluid reservoir via a fluid path which is connected to the culture chamber via an aperture in the culture chamber. The aperture is smaller than the diameter of the cell to be cultured such that the cell is maintained within the cell culture chamber.

An ovum collection device (20) includes a handle (4) and a collection needle (3) extending from the handle. The collection needle has a sharpened tip (44) for insertion into a follicle of an ovary. A collection duct (5) in fluid communication with the collection needle extends from the handle to a collection bottle (6). A heating arrangement (14) is used to maintain the collection needle at a selected temperature to prevent damage to an oocyte. The heating arrangement may be associated with a needle guide (72) on an ultrasonic probe such as a transvaginal ultrasonic probe (70).
摘要:
A linkage support system and method for mounting and supporting a linkage on a work vehicle. The linkage support system includes a load bearing support and a removable linkage pin support rigidly attached to the load bearing support. The work vehicle is, typically, an earthmoving vehicle which includes a frame, a work tool such as a bucket, and a linkage for manipulating the work tool. The load bearing support may be a portion of the frame of the vehicle.
摘要:
A method of fabricating bipolar transistors with increased gain. A base region is formed adjacent the collector (or emitter) region of the transistor, and a portion of the base region is then removed by etching. The emitter (or collector) is then formed by diffusing dopant into the base region where the portion has been removed, with the base region separating the emitter and collector having reduced thickness due to the etching. Advantageously, the base region may be formed with a more heavily-doped region overlying a less heavily-doped region, with a part of the more heavily-doped region removed by etching, thereby providing a highly conductive path to the lower conductivity base region separating the emitter and collector regions. The process steps are compatible with conventional integrated-circuit fabrication processes.

A process for fabricating oxide-isolated vertical bipolar transistors and complementary oxide-isolated lateral bipolar transistors incorporates the steps of growing a doped epitaxial layer of single-crystal silicon on a silicon substrate, applying a first insulation material in a selected pattern over the epitaxial layer to define oxide-isolation regions and device regions, etching grooves in the areas in which oxide-isolation regions will be formed, applying a self-aligned base insulation material over those portions of the interface between the first insulation material and the grooves which bound the region between the base of any vertical bipolar transistor to be formed and the emitter of any lateral bipolar transistor to be formed, applying an impurity of a conductivity type opposite to the conductivity type of the epitaxial layer to those groove areas not covered by the self-aligned base insulation material, the impurity serving to prevent emitter-to-collector inversion along the wall of the base of any vertical bipolar transistor without shorting the emitter and collector of any lateral bipolar transistor, forming oxide-isolation regions in the grooves and forming the vertical bipolar transistors and the lateral bipolar transistors in the device regions. The process of the present invention will produce discrete lateral bipolar transistors, discrete vertical bipolar transistors capable of operation in the conventional mode or in the inverse mode, or a composite structure which merges both a vertical bipolar transistor and a lateral bipolar transistor together on the same silicon island to form an injection-logic gate in which the base of the vertical bipolar transistor serves as the collector of the lateral bipolar transistor, the vertical transistor being operated in the inverse mode.
