  • Patent number: 5576523
    Abstract: A mechanical linkage for independently opening and closing a plurality of associated switches is provided by the invention. The linkage comprises a plurality of connecting rods that provide the initial driving force to open or close the switch, cranks for opening and closing the contacts of respective switches, linking elements which couple together the connecting rods and the cranks, and a number of lever assemblies having a bearing ring interfaced thereto. The bearing rings provide a supportive interface between two linking element but permit the linking elements to rotate independently from one another. The lever assemblies also provide an interface for the connecting rods and linking element. According to a method of the present invention, a connecting rod is actuated in response to a signal to cause the lever assembly to pivot. The linking rod interfaced with the connecting rod via the lever assembly is then rotated in response to the pivoting.

  • Patent number: 5574418
    Abstract: A three-phase autotransformer improving balance of three-phase voltages and currents. An iron core has three legs corresponding to the three phase. A common winding and/or a serial winding of each phase includes three coils. Two of the three coils are wound on the same leg associated with the phase of the coils, and the other one coil is wound on another leg. The two coils and the other one coil are connected in series to generate magnetic flux in the opposite directions. Since the common winding and/or the series winding includes coils which are wound on different legs associated with different phases, and which generate flux in opposite directions, the balance of three-phase input voltages and currents, and output voltages and currents is automatically maintained.

  • Patent number: 5574417
    Abstract: An open magnetic resonance imaging (MRI) magnet having first and second spaced-apart superconductive coil assemblies each including a toroidal-shaped coil housing containing a superconductive main coil. A generally annular-shaped permanent magnet array is associated with each coil assembly, being generally coaxially aligned with the associated coil assembly and being spaced radially inward and radially apart from the associated coil assembly's superconductive main coil. The permanent magnet arrays overcome the gross magnetic field distortions in the imaging volume of the superconductive main coils (created by the open space between the magnet's superconductive coil assemblies) to produce a magnetic field of high uniformity within the imaging volume.

  • Patent number: 5574266
    Abstract: A deceleration sensor switch (10) comprises electrical contacts (50, 52) and a mass (14) movable between an unactuated position in which the electrical contacts are open and an actuated position in which the electrical contacts are closed. The mass is biased towards the unactuated position. A cylinder (30) includes an end portion (44) and a cylindrical wall portion (34) extending from the end portion to define a chamber (35) inside the cylinder. The end portion includes a metering orifice (36) for allowing air to flow between the chamber and outside the cylinder. A shaft (22) interconnects the mass and a truncated cone (24). The cone has a skirt end (26) and is movable in one direction relative to the chamber to displace air from the chamber through the metering orifice to outside the cylinder upon the mass moving from the unactuated position to the actuated position in response to the mass being subjected to deceleration of at least a predetermined magnitude.

  • Patent number: 5569887
    Abstract: A weighing device has not only a scale cell which weighs an object and outputs a weight signal indicative of the measured weight value but also a vibration-detecting load cell for detecting the vibrations of the floor to which the scale cell is set such that the effects of the floor vibrations can be subtracted from the weight value detected by the scale cell. The vibration-detecting load cell has attenuation-adjusting members adhesively attached to strain-generating parts of its load-sensitive element such that the attenuation constant of the load cell is thereby increased at least by a factor of 2. The usable dynamic range of the load cell can thus be increased while the load cell is kept compact. Butyl rubber members can be used for this purpose.

  • Patent number: 5569889
    Abstract: A retractable key assembly comprising a key top and an externally extending pivot arm. The pivot arm allows arcuate movement of the key top about a pivot axis such that the key top can be used in an upper, active keying position or stored in a lower, inactive position. The use of a pivot arm enables a lower profile keyboard when the keyboard is in the retracted, inactive position. Displacement of the internal actuation assembly allows the keytop to actually rest on the keyboard base. A translatable base member is useful to raise or retract the key assembly. The disclosed key assembly provides an aesthetic appearance and improved keying accuracy, relative to conventional keyboard arrangements.
