摘要:
A bobbin for a pickup including a base and a top or cover spaced and connected by a post structure integral thereto. The post structure has one or more cavities for receiving one or more pole pieces. The post structure includes a plurality of lateral windows so that the one or more pole pieces in the one or more cavities would be immediately adjacent windings of one or more coils to be wound on the bobbin.

A disc stabilization system comprises a spinning disc with a disc surface deflectable by shock. The disc surface is in contact with a gas layer adjacent the disc surface. When the suspension system is subjected to a mechanical shock, the disc can deflect. The amplitude and duration of the deflection due to mechanical shock is limited by a wing feature. The wing feature includes an aerodynamic surface that interacts with the gas layer to generate an aerodynamic force on the disc surface. A strut supports the wing feature over the disc surface in a position such that the aerodynamic force increases as the disc surface deflects toward the aerodynamic surface.

摘要:
An improved edgewise orthodontic bracket is disclosed. In one embodiment, a bracket comprises a single pair of opposing T-shaped tie wings which define an archwire slot therebetween. Notches are provided on each of the mesial and distal sides of the center leg of each T-shaped tie wing for selectively receiving a ligating device. The notches are defined in the gingival/occlusal edges of the tie wings and comprise sloped portions that extend labially towards the archwire slot. Convex sidewall portions and convex floor portions are provided in the archwire slot adjacent to the notches. The body of the bracket is interconnected to a base that includes a continuous series of characters that serve as texturing to facilitate bonding of the bracket with a tooth. A discontinuous perimeter rail may be used at the edge of the base. A method for forming a bracket is also provided.
摘要:
A data storage disk having a latent illuminance discrimination marker for determining whether the data storage disk is suitable for use in a disk drive. A light source illuminates the marker and the marker emits illuminance, preferably as phosphorescence. A detector detects the emitted illuminance, and a predetermined characteristic of the marker in the frequency domain is determined. The frequency domain response may be either a phase response or an amplitude response, or both. The frequency domain response provides identification of different types or generations of data storage disks or provides a secure keying mechanism for authorized access to proprietary software.

Plasma enhanced chemical vapor deposition (PECVD) reactors and methods of effecting the same are described. In a preferred implementation, a PECVD reactor includes a processing chamber having a first electrode therewithin. A second electrode is disposed within the chamber and is configured for supporting at least one semiconductor workpiece for processing. A first RF power source delivers RF power of a first frequency to the first electrode. A second RF power source delivers RF power of a second frequency to the second electrode. Preferably the first and second frequencies are different from one another, and even more preferably, the first frequency is greater than the second frequency. The preferred reactor includes a thermocouple which provides temperature information relative to one of the electrodes. According to a preferred implementation, the power loop developed by the first RF power source is grounded interiorly of the chamber in a manner which reduces if not eliminates interference with other reactor components including the thermocouple.
摘要:
Method and apparatus for freon and other refrigerant matching, particularly for servicing of air conditioning systems for automotive applications. The matching process is based upon the comparison of resistance or infrared absorption or other data readings of a gas-sensing resistance or infrared absorption or other transducer applied to the refrigerant fluid under test and corresponding data from reference refrigerants.
摘要:
An ultrasonic surgical device in accordance with the present invention includes a transmission component adapted to receive ultrasonic vibration from a transducer assembly and to transmit the ultrasonic vibration from a first end to a second end. An inner damping member surrounds at least a portion of the transmission component. The dampening member is adapted to contact the transmission component to dampen undesired vibration during ultrasonic transmission.
