  • Patent number: 6164942
    Abstract: A charge cooled rotary engine includes a housing, a first end plate, and a second end plate. The housing and end plates combine too define a closed chamber. A rotor disposed within the housing includes three flanks, a cylindrical hub, and a web extending transversely from the hub and joining medial portions of the flanks to the hub. The web, flanks, and hub form rotor cavities on opposite ends of the rotor. Inlets formed in the end plates for receiving fuel/air charge terminate in entry ports facing the closed chamber. Distribution chambers, formed in the end plates adjacent the entry ports, are open to the closed chamber. The entry ports directly communicate with the rotor cavities and are isolated from direct communication with any of the intake, compression, and combustion chambers by the rotor flanks.

  • Patent number: 6146509
    Abstract: An inverted field circular planar magnetron sputtering device is described that produces coatings with a high degree of thickness uniformity on round wafer-like substrates. It is a compact source with no moving mechanical parts. DC signals applied to low power electromagnetic coils provide control of the coating thickness uniformity throughout the life of the target. AC signals applied to the coils oscillate the sputtering rings to improve target utilization and maintain a clean target surface. Utilization of target material is about 40% for both magnetic and non-magnetic target materials. The design accommodates versions for both direct and indirect water cooling.

  • Patent number: 6037944
    Abstract: An effective method and apparatus for organizing and processing chunks of interrelated information (or "thoughts") using a digital computer is disclosed. The invention utilizes highly flexible, associative thought networks to organize and represent digitally-stored thoughts. A thought network specifies a plurality of thoughts, as well as network relationships among the thoughts. A graphical representation of the thought network is displayed, including a plurality of display icons corresponding to the thoughts, and a plurality of connecting lines corresponding to the relationships among the thoughts. Each of the thoughts is associated with one or more software application programs, such as a word processing or spreadsheet utility. Users are able to select a current thought conveniently by interacting with the graphical representation, and the current thought is processed by automatically invoking the application program associated with the current thought in a transparent manner.

  • Patent number: 6026021
    Abstract: A memory circuit that reduces memory operation access time and stress on the memory cells due to memory operations. The memory circuit comprises a semiconductor memory array having a continuously addressable memory space being divided into a plurality of memory array blocks; a memory addressing circuit capable of addressing said continuously addressable memory space of said semiconductor memory array; a memory operation circuit for performing a memory operation on a selected memory cell within a selected memory array block among said plurality of memory array blocks; and a switching network responsive to said memory addressing circuit for selectively coupling said memory operation circuit to said selected memory cell of said selected memory array block by way of said conductive lines, for performing said memory operation on said selected memory cell.
