  • Patent number: 8649767
    Abstract: A Femtocell base station has a determination means and a transmission means. The determination means, upon receiving a location update request message from UE (User Equipment), determines whether a first message that prompts the UE to again attempt a location update should be transmitted to the UE, whether a second message that prompts the UE to divert to another network should be transmitted to the UE, or whether a third message that notifies the UE that the location update request is accepted should be transmitted to the UE. The transmission means transmits to the UE either the first message, or the second message, or the third message in accordance with the determination of the determination means.

    Abstract: A inkjet printer includes an ejection head, a curing-light-emitting part, a head retaining part, a relative scanning part, a drive output detecting part, and a curing-light-emission-control part. The ejection head ejects a photocuring liquid onto a printing medium retained by a medium retaining part. The curing-light-emitting part emits curing light onto the printing medium. The head retaining part retains the ejection head and the curing light emitting part. The relative scanning part performs relative movement of the head retaining part and the medium retaining part. The drive output detecting part detects an output of a drive source of the relative scanning part. The curing-light-emission-control part controls the curing-light-emitting part based on a detection result from the drive output detecting point.
