  • Patent number: 8833511
    Abstract: In a conventional hard material insulator, reproduced sound can be tuned with use of characteristics of the material; however, various types of acoustic materials have specific high frequency characteristics, and thus their acoustic effects lack versatility, require compatible audio devices, and change with environment, musical genre, etc. To address this, a wind-bell member (resonant member) is arranged in parallel with a main propagation path of vibration transferred from an audio device to an insulator. Accordingly, a vibration system of a wind-bell having a tone determined by many factors such as a fundamental tone, harmonic tones, lingering sound, and fluctuation assists (enhances) high frequency vibration propagated from the audio device. As a result, due to the above assist action that is different in principle from a conventional type, acoustic characteristics such as a sense of localization, resolution, and a sense of transparency and scale a sound image can be dramatically improved.

  • Patent number: 8292274
    Abstract: A spring system for relatively displacing elements attached to end mounts of the rod assembly comprises a housing having a rod member movable between extended and retracted positions relative thereto, and a first compression spring in the housing surrounded by a second compression spring for biasing the rod member to one of an extended or retracted position relative to the housing. The two springs are oppositely wound whereby, from a compressed condition, the spring rod exerts an expansion force which increases at a linear rate. The spring system includes a valve arrangement to control the rate at which the spring rod moves from a retracted position to an extended position.

  • Patent number: 6565073
    Abstract: A suspension assembly for a motor vehicle includes a wheel assembly attached to the frame of a motor vehicle for movement in response to uneven roadway surfaces. A first inductive coil attached to the frame is mounted along an axis, and a second inductive coil is mounted co-axially with the first inductive coil and for movement with the wheel assembly. The inductive coils are movable relative to one another along the axis. An electromagnetic force generated by the inductive coils provides spring and dampening forces for the motor vehicle. Further, variation in the inductance between the coils is measurement to determine the relative position between the coils in order to monitor motor vehicle ride height.

  • Patent number: 5425531
    Abstract: A spring system comprising an axially movable, generally conically shaped plug having a flange on its larger diameter end, and a coil spring, within which the plug is axially arranged, formed in two co-axial integral inner and outer coil spring sections. The spring inner section coils having diameters which are sized to closely conform to the portions of the outer surface of the plug which they overlay, and the spring outer section coils surrounding and being radially spaced from the inner section of the spring. The free end of the inner section is fixedly anchored to a support member and the free end of the outer section engages a support surface. The sections are integrally connected by a common coil arranged to engage the plug flange. When the plug is initially moved endwise within the spring, the coils of the inner section are tightened and stretched around the conically shaped plug surface. Further movement of the plug compresses the outer spring section between the plug flange and the support surface.

  • Patent number: 4889327
    Abstract: A helical spring composed of a plurality of parallel, coiled strands of spring wire with such strands being unconnected along most of their length but being joined together at least at one end of the spring. In a preferred embodiment, such strands or wires are welded together at opposite ends of the spring. Such a spring is formed by incrementally advancing a plurality of wires in contiguous, parallel relation towards a wire-coiling station and then, at the termination of a coiling step, interrupting such advancement to sever the wires through, or immediately adjacent to, a first welded zone while at the same time welding such wires together in a second zone spaced a precise distance from the point of the severing operation.

  • Patent number: 4776574
    Abstract: This invention relates to an improved seat belt retractor rewind spring assembly. In accordance with this invention, a rewind spring assembly is provided having the "bridling" effect wherein the coiled flat strip spring is retained by a spring cap which exerts an outwardly directed bending load on the end of the spring which engages the cap. This bridling effect has been found to increase the efficiency of the coil spring. The rewind spring assembly according to this invention improves over prior art designs in that completely automated assembly is possible through the provision of a novel spring cap design, assembly fixture and assembly process.
