  • Publication number: 20050194898
    Abstract: A diffusion barrier system for a display device comprising a layer system with at least two layers of dielectric material, wherein at least two adjacent layers of that layer system comprise the same material. A respective method for manufacturing such a diffusion barrier system in a single process chamber of a plasma deposition system has the steps of introducing a substrate to be treated in said process chamber, discretely varying in a controlled manner during deposition at least one process parameter in the process chamber, without completely interrupting such process parameter, which results in layers with different properties and finally unloading said substrate from said process.

  • Publication number: 20040258145
    Abstract: The invention describes a number of differential, balanced high-speed circuits that permit the design of a receiver with Electronic Dispersion Compensation (EDC) on a single semiconductor substrate, including the functions of an analog Fast Forward Equalizer (FFE), a Clock and Data Recovery, a Decision Feedback Equalizer (DFE), enhanced by additional circuits that permit control of the slicing level to compensate for pulse distortion, and control of the phase offset to set the optimal eye sampling time when a distorted signal is received. To provide the utmost speed of operation, all circuits including the phase locked loop, operate as differential circuits which include a number of improvements in the design of the charge pump, the decision feedback equalizer, the slicing level control, and others.

  • Patent number: 6754615
    Abstract: Method of simulating the performance of a vehicle on a roadway on a power train test bed with the help of torque-controlled electric load machines mounted on the shafts of the power train of the vehicle and with the help of a computer with a vehicle model stored therein and a tire model simulating the slip-dependent friction, in which method the angular wheel speed is measured on at least one of the shafts, and the tire model determines a force transmitted from the tire to the roadway at this angular wheel speed on the basis of the tire model using a vehicle velocity and a tire normal force, and it also determines a setpoint torque for this force for the torque-controlled load machine mounted on this shaft, in such a way that a difference corresponding to the actual slip is established between the measured angular wheel speed and a nominal angular wheel speed value corresponding to the vehicle velocity used in the tire model and calculated in the vehicle model with feedback of the force transferred to the roa

  • Patent number: 6637076
    Abstract: A fabricated steel pipe repair clamp having a steel band and interlocking steel lugs having respective tension bars and tightening bolts or studs forming the tightening assembly. The tightening assembly comprises a welded stud lug assembly, and a tension bar lug welded assembly, each having a base plate, and a backup plate. The two folded terminals of the clamping metal band are welded between the base plate and the backup plate forming the respective lug bodies. The laminated weld forming the lug assembly results in a stronger lug body backup plate and provides an even clamping force. An alternative embodiment combines the base plate and the backup plate connected to form jaws. Another embodiment employs an offset backup plate to form the lugs to receive the band ends in a recess formed between the tensioner bars and between the studs shank portions.

  • Patent number: 6588070
    Abstract: A low profile pipe leak repair clamp for sealing a leak in a wide range of pipe sizes includes a flexible, circular metal band lined with a sealing gasket. The clamp a tightening assembly comprising a pair of open and close lugs and a nut and bolt for tightening the band around a leaking pipe. Each lug includes an open slot leading to an inner recess adapted to firmly engage a folded end of the flexible metal band, the recess being of such dimensions as to maintain each folded end in its original shape, thus preventing the metal band from being pulled from the slot upon tightening the clamp. Each lug has an upper jaw and a lower pressure jaw forming the slot and recess. The lower pressure jaw is arcuate at its end and its lower surface chamfered downward to the lower lug surface.

  • Patent number: 5594234
    Abstract: The invention is a single piece deep downset exposed lead frame (10) that can be used in current production processes. A single lead frame (10) has a die mount pad (12) that is formed with a downset or cavity into which the semiconductor die (20) is mounted. Wings (14, 15, 17, 18) lock the die pad in the device package (21) and increase the length of potential moisture paths (34a). The downset die pad (12) provides direct thermal contact of the die mount pad (12) to an external heat sink, eliminating the need for a heat slug internal to the package. The exposed die pad (12) can also be used as an RF ground connection to an RF circuit ground plane.
