Abstract: A wheel reconditioning apparatus includes an upright post connected to a base seat, a transverse carrier, a first drive unit, a cutter unit, a second drive unit and a working table. The upright post has a support front surface. The transverse carrier is disposed slideably on the support front surface. The first drive unit is mounted between the upright post and the transverse carrier to move the transverse carrier. The cutter unit is disposed slideably on a carrier front surface of the transverse carrier. The second drive unit is connected between the transverse carrier and the cutter unit to drive the cutter unit. The working table is mounted to the base seat and is oriented toward the cutter unit.

Abstract: An illumination device includes a signal reception unit capable of receiving an audio signal from outside, a musical piece extraction unit capable of extracting continuous consonant sounds in the audio signal as a musical piece, a performance state detection unit capable of detecting start/end of performance of the musical piece according to a result of extraction by the musical piece extraction unit, a first illumination lamp capable of radiating ultraviolet rays, a second illumination lamp capable of radiating white light, and an illumination control unit capable of controlling on/off of the first illumination lamp, and of controlling on/off and illuminance of the second illumination lamp, The first and the second illumination lamps are turned on in response to detection of the start of performance, and the first and the second illumination lamps are turned off in response to detection of the end of performance.
