  • Publication number: 20220385742
    Abstract: A transmitting terminal can transmit a content held by itself to a specific receiving terminal having no email software as if using a mailer. The transmitting terminal (10) and the receiving terminal (20) are connected to a delivery server (30) via a network (4). The delivery server (30) comprises: a database (36) for registering the device ID that specifies the receiving terminal (20); a content storage (39) for temporarily storing a content transmitted from the transmitting terminal (10); and table (33, 37) for managing contents separately on a per device ID basis of the receiving terminal. The delivery server (30), when receiving a request from the receiving terminal (20), refers to the tables (33, 27) and transmits to the receiving terminal (20) a content, the transmission destination of which corresponds to the device ID of the receiving terminal (20).

  • Patent number: 11441668
    Abstract: Provided are a motor device and a method for manufacturing the same that can accurately and consistently provide a support shaft to a case and enhance the strength for fixing the support shaft to the case. A small-diameter part having a smaller diameter than a large-diameter part is formed through drawing. The large-diameter part and a step part are embedded in a gear case. The small-diameter part is exposed outside the gear case. The dimensional accuracy (dimensional tolerance ±?) of the external diameter of the small-diameter part is enhanced. The small-diameter part can be set, without rattling, in a lower mold for molding the gear case. Consequently, the support shaft can be accurately and consistently provided to the gear case. Because the large-diameter part and the step part are embedded in the gear case, the resistance of the support shaft against pulling from the gear case can be enhanced.
