  • Patent number: 9677775
    Abstract: Provided is a door for a cooking appliance, such as an oven range, with multiple spaced apart glass panels. An interlocking mechanism promotes a proper installation of the glass panels, and interferes with the installation of the glass panels or with operation of the appliance if at least one of the panels is not properly installed. A switch with a plunger can be installed in the door, which allows the appliance to operate only when a failsafe electrical circuit is closed corresponding to a selected position of the plunger when the door is closed. The plunger is prevented from retaining that selected position if at least one of the glass panels is improperly installed or if a top cap is not properly seated or installed above the glass panels.

  • 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.

    Abstract: An apparatus for securing a protective panel over a window includes at least one telescoping retainer bar that is tightly fixed within a window frame, adjacent the panel. Spring-biased locking buttons removably seat within one or more longitudinally-disposed apertures to fix the retainer bar at a desired length. At each end of the bar is a resilient pad that firmly engages one of two opposing sides of a window or door frame. One of the pads is movable relative to the bar to further tighten the bar within the frame once the telescoping bar has been extended as far as possible. The pad at the opposing end includes a biasing means for further anchoring the bar within the frame.

  • Patent number: 5499791
    Abstract: A machine with vibration source includes a frame for carrying a vibration source such as a motor. A housing is attached to a bottom of the frame, in which a sphere made of a rigid material is housed rotation free in a manner that a portion of the sphere is projected from an opening at the bottom of the housing. The surface of a plate made of a rigid material contacts the portion of the sphere projecting from the housing and the plate is surrounded by a member of an elastic material. The elastic member has an upwardly extending portion which surrounds the housing, and therefore, the elastic member controls the relative position between the sphere and the plate, and resultingly, rolling of the machine can be suppressed. In addition, since the sphere can be rotated on the plate, horizontal vibration of the machine is absorbed to be suppressed. Furthermore, since the sphere is supported by the plate and the plate is supported by a floor via the elastic member, vertical vibration of the machine is also suppressed.
