  • Publication number: 20240112571
    Abstract: A congestion prediction device, a congestion prediction method, and a storage medium are provided. A mapping outputs an output variable when input variables are input to the mapping. The output variable indicates a degree of congestion in a predetermined specific area. The mapping is learned in advance by machine learning. The input variables include congestion variables. Each of the congestion variables indicates a degree of congestion in the specific area at regular time intervals within a specific period. The output variable indicates a degree of congestion after a lapse of the regular time interval from an end time of the specific period.

  • Publication number: 20240075736
    Abstract: A printing apparatus includes a mounting unit, a tank, a pump, a detection unit, an obtainment unit, and a control unit. The mounting unit is configured so that a head that ejects ink can be mounted in a replaceable manner. The tank contains ink to be supplied to the head via a tube. The pump discharges ink to an outside of the head. The detection unit detects that the head mounted on the mounting unit has been replaced. The obtainment unit obtains information of a usage history which indicates whether or not the head mounted as a replacement has been used. The control unit controls a discharge operation, which is performed by the pump after head replacement, to be changed based on the information of the usage history.

  • Publication number: 20220108882
    Abstract: A processing method of a workpiece with a circular disc shape includes sticking a tape to one surface of the workpiece and integrating the workpiece and a frame through the tape, holding the workpiece by a holding unit with the interposition of the tape, and irradiating the other surface of the workpiece located on the opposite side to the one surface with a pulsed laser beam having such a wavelength as to be absorbed by the workpiece from the side of the other surface. In irradiating the laser beam, the other surface is annularly irradiated with the laser beam in the state in which the orientation of the laser beam is adjusted in such a manner that the laser beam has an angle of incidence formed due to inclination with respect to a normal to the other surface of the workpiece by a predetermined angle.
