  • Ceiling fan having reinforcements
    Patent number: 9915268
    Abstract: A ceiling fan includes blade (11) that is integrally formed of root (12), vane (13), and step (14) for maintaining vane (13) in a state inclined from horizontal. Blade (11) includes bend (16), first reinforcement (17) on upstream side (11c), and a plurality of second reinforcements (18) between bend (16) and first reinforcement (17). First reinforcement length (17a) is longer than second reinforcement length (18a). Further, the ceiling fan includes blade drop prevention portion (37) for locking blade (11) to support (10).

  • Noise suppressor
    Patent number: 5388160
    Abstract: In a noise suppressor, a noise signal detected by a first detector is inputted to an adaptive filter and a FIR filter. An output signal of the adaptive filter is reproduced by a speaker. The signal reproduced by the speaker and a noise signal from a noise source are detected by a second detector. The signal detected by the second detector is band-limited by a filter circuit and sent to a LMS computing circuit. The LMS computing circuit updates a coefficient of the adaptive filter so as to minimize an output signal of the filter circuit in response to an output signal of the FIR filter and an output signal of the filter circuit.

    Patent number: RE48538
    Abstract: A ceiling fan includes blade (11) that is integrally formed of root (12), vane (13), and step (14) for maintaining vane (13) in a state inclined from horizontal. Blade (11) includes bend (16) on upstream side (11c), first reinforcement (17) on upstream downstream side (11c) (11b), and a plurality of second reinforcements (18) between bend (16) and first reinforcement (17). First reinforcement length (17a) is longer than second reinforcement length (18a). Further, the ceiling fan includes blade drop prevention portion (37) for locking blade (11) to support (10).
