  • Publication number: 20020186093
    Abstract: Multi-frequency dielectric resonator oscillator The invention provides a dielectric resonator oscillator DR, especially for transmission devices whose oscillating frequency may take several values. The oscillator uses two interfering conductors 30 and 31 switched so that they may or may not form a metal plane close to the dielectric resonator DR in order to vary the frequency of the oscillator while using a single resonator. The interfering conductors 30 and 31 are located in the cavity CAV close to the resonator DR and the switching means may or may not establish an electrical contact between the said interfering conductors 30 and 31.

  • Publication number: 20020187636
    Abstract: Mask and integrated circuit fabrication approaches are described to facilitate use of so called “full phase” masks. This facilitates use of masks where substantially all of a layout is defined using phase shifting. More specifically, exposure settings including relative dosing between the phase shift mask and the trim masks are described. Additionally, single reticle approaches for accommodating both masks are considered. In one embodiment, the phase shifting mask and the trim mask are exposed using the same exposure conditions, except for relative dosing. In another embodiment, the relative dosing between the phase and trim patterns is 1.0:r, 2.0<r<4.0. These approaches facilitate better exposure profiles for the resulting ICs and can thus improve chip yield and increase throughput by reducing the need to alter settings and/or switch reticles between exposures.

  • Publication number: 20020188924
    Abstract: A method for producing a computer readable definition of photolithographic mask used to define a target pattern is provided. The phase shift mask patterns include phase shift windows, and the trim mask patterns include trim shapes, which have boundaries defined by such sets of line segments. For a particular pair of phase shift windows used to define a target feature in a target pattern, each of the phase shift windows in the pair can be considered to have a boundary that includes at least one line segment that abuts the target feature. Likewise, a complementary trim shape used in definition of the target feature, for example by including a transmissive region used to clear an unwanted phase transition between the particular pair of phase shift windows, includes at least one line segment that can be considered to abut the target feature.

  • Publication number: 20020186718
    Abstract: A clock system includes a provisioning layer corresponding to a plurality of input clocks, and a plurality of layers arranged according to a hierarchy. The first layer in the hierarchy is operable to arrange the input clocks into groups and for each group select a corresponding group output clock. The remaining layers in the hierarchy are operable to arrange the group output clocks from a next layer higher in the hierarchy into groups and for each group select a corresponding group output clock. The lowest layer in the hierarchy is operable to select one of the group output clocks from the next layer higher in the hierarchy as a selected clock.

  • Patent number: 6490772
    Abstract: A method for forming a one-piece skip body with a concave cross section from a large metal sheet (1) by imparting an approximate cross section to the sheet using shaping mechanisms (2) is disclosed. According to the method, the approximate cross section is maintained while a sealing plate (10) is secured to one end (9) and a stiffening reinforcement member (13) shaped according to the final cross section is attached to the other end (12). The longitudinal edges are stiffened then the most curved areas are mechanically treated and the shaping mechanisms (2) are released. The method is relevant to skip manufacturers and more generally to builders of utility vehicles.

  • Publication number: 20020183516
    Abstract: Improved methods for generating a —C—C— bond by cross-coupling of a transferable group with an acceptor group. The transferable group is a substituent of an organosilicon nucleophile and the acceptor group is provided as an organic electrophile. The reaction is catalyzed by a Group 10 transition metal complex (e.g., Ni, Pt or Pd), particularly by a palladium complex. Certain methods of this invention use improved organosilicon nucleophiles which are readily prepared, can give high product yields and exhibit high stereo selectivity. Methods of this invention employ activating ions such as halides, hydroxide, hydride and silyloxides. In specific embodiments, organosilicon nucleophilic reagents of this invention include siloxanes, particularly cyclic siloxanes. The combination of the cross-coupling reactions of this invention with ring-closing metathesis, hydrosilylation and intramolecular hydrosilylation reactions provide useful synthetic strategies that have wide application.
