  • Publication number: 20070086254
    Abstract: Techniques for interchanging positions of external terminals of an integrated circuit chip are disclosed. According to one aspect of the present invention, a chip comprises at least a pair of external terminals for communicating with other components or circuits, an internal circuit and an interchangeable unit coupled between the external terminals and the internal circuit. The interchangeable unit is configured to interchange the external terminals electronically such that the chip remains compatible in various versions involving an change of the terminals thereof, wherein the an interchangeable unit is controllable externally by a selecting pin applicable to either a high level or a low level to cause the external terminals interchanged.

  • Patent number: 7070398
    Abstract: A blood pump has an impeller rotatably disposed and magnetically suspended within a cavity of a stator by a plurality of magnetic bearings including an axial bearing to support the impeller axially in the cavity. The axial bearing includes adjacent impeller magnets and adjacent stator magnets with axially aligned polarities and reverse polarities with respect to adjacent magnets. A motor includes impeller magnets on the impeller and coils and poles associated with the stator. Radial permanent magnet and electromagnetic bearings are also included. The magnetic bearings and the motor have stator magnets or coils and poles disposed radially across the fluid passage from corresponding impeller magnets to define an annular gap positioned radially between the impeller and the stator, and positioned radially between all of the plurality of magnetic bearings, creating a straight through blood path without secondary flow paths.

  • Patent number: 6716705
    Abstract: An EEPROM device and process for fabricating the device having a retrograde program junction region includes providing a semiconductor substrate having a principal surface and forming a program junction region in the semiconductor substrate. The program junction region is characterized by a doping concentration profile in which a maximum doping concentration is displaced away from the principal surface. The doping concentration profile can be obtained by forming a first portion of a tunnel dielectric layer on the principal surface, then introducing doping atoms into the program junction region, followed by forming a second portion of a tunnel dielectric layer. In another embodiment, the doping concentration profile in the program junction region is formed by two consecutive doping processes, in which either the same doping species is introduced at different energies, or a second doping process is carried out with a dopant having a different conductivity type than the first dopant.
