  • Publication number: 20060146659
    Abstract: A beat density detecting apparatus and an information playback apparatus are provided to detect distinctive characteristics that music or the like has and to provide the same as a novel information volume. Playback data read out from an information recording medium, such as an optical disc, and sub-code data containing the information of an elapsed track time indicating a recording position of the playback data are provided to a beat detecting unit and a beat position detecting unit, respectively. The beat detecting unit detects the number of occurrences of a change in amplitude at each predetermined frequency of the playback data, and the beat position detecting unit detects an elapsed track time from the sub-code data. Further, a beat density computing unit finds the number of occurrences with respect to the elapsed track time as the characteristics information of a beat density.

  • Patent number: 5467912
    Abstract: There is provided a reflow soldering apparatus for soldering electronic parts to a circuit substrate by blowing various inert hot gases of a desired density and temperature. A device for detecting whether or not a processing object is being conveyed into the apparatus is provided, so that the amount of inert gas to be supplied and the gas blowing speed are decreased when no processing object is present inside the apparatus. As a result, the amount of gas which flows out is made small, and a decrease in the temperature of the apparatus can be prevented. When the processing object is conveyed into the apparatus, the amount of supplied gas is increased so as to obtain a sufficient gas density. Thus, it is possible to prevent solder from being oxidized, and satisfactory solderability can be obtained.
