  • Publication number: 20060163661
    Abstract: A semiconductor product and a method for fabricating the semiconductor product provide a pair of gate electrodes formed with respect to a pair of doped wells within a semiconductor substrate. One of the gate electrodes is formed of a first gate electrode material having a first concentration of an electrically active dopant therein. A second of the gate electrodes is formed of the first gate electrode material having less than the first concentration of the electrically active dopant therein, and formed at least partially as an alloy with a second gate electrode material. The semiconductor product may be formed with enhanced efficiency.

  • Patent number: 4467351
    Abstract: X-rays at a minimal exposure level representing 25% of the conventional exposure are emitted from an X-ray tube and pass through a subject, such as a patient undergoing radiographic examination. The minimal exposure X-rays are detected by a preselected detector means, such as illuminated film, an X-ray intensifier, a CT scanner, a radioactive nuclear scanner or an image intensifier in combination with a television camera. The detector converts the radiation emerging from the subject to light images in the case of the video system. The light images are converted to electronic signals in a television camera. In the case of the CT scanner and nuclear scanner a photodiode array or scintillation crystal is actuated by the emerging radiation to generate an electrical current proportional to the intensity of the emerging radiation. The electronic signal is transmitted to an analog to digital converter, and the digital signal is transmitted to a computer for storage.

  • Patent number: 4105025
    Abstract: A supportive wrapping for a surgical support or orthopedic cast is produced by providing a bandage material which is impregnated or coated with a molten polyurethane polymer that is crystallizable in a predetermined, delayed time period at room temperatures or at temperatures tolerable to human skin and permitting the polyurethane polymer to crystallize on the bandage material to form a strong, supportive, self adhered wrapping while standing at or cooling to room temperature.
