  • Patent number: 11559869
    Abstract: A wafer edge polishing apparatus includes a cleaning mechanism exhibiting a superb effect of cleaning slurry residue adhered on a chuck table. This edge polishing device is provided with: a chuck table which sucks/holds a wafer; a rotation drive mechanism which rotates the chuck table; an edge polishing unit which polishes an edge of the wafer while supplying slurry to the wafer, which is rotating while being sucked/held by the chuck table; and a cleaning unit which removes slurry residue on the chuck table. The cleaning unit includes a cleaning head, and cleans the chuck table through high-pressure cleaning and brush-cleaning by using the cleaning head, wherein the cleaning head is provided with a high-pressure jet nozzle and a brush surrounding the periphery of the high-pressure jet nozzle.

  • Publication number: 20220319491
    Abstract: A vehicle sound generation device includes a controller that generates a sound signal representing a sound and sets the localization of the sound, and left and right front speakers and left and right rear speakers that output sounds corresponding to the sound signals for which localization has been set by the controller, in which the controller sets the localization of the sounds based on the change amounts (such as the pitch rate, the torque change amount, the roll rate, and steering angular speed) per unit time of the physical quantities correlated with a driving operation by the driver of the vehicle so that the sound image of at least part (low frequency component) of frequency components of the sound is located toward the wheel where the ground load is increasing according to the driving operation.

  • Publication number: 20090228194
    Abstract: A navigation apparatus includes a storage unit, an acquiring unit, a comparing/identifying unit, an updating unit, and a control unit. The navigation apparatus stores data required for the navigation operation in a plurality of areas and also acquires the data from an external recording medium. The data stored in the plurality of areas is updated based on a comparison with the acquired data to identify which is the most recent data. At least while the updating of data is in progress, the data that is not in the process of being updated is used to perform navigation operation.
