Abstract: A gear shift control device of an automobile including a driving motor, a relay clutch capable of disconnecting an engine, includes memory storing a gear shift map for determining the switching start timing of the gear position, a transmission control unit that switches the gear position based on the gear shift map, a regeneration control unit, and a relay clutch control unit. The gear shift map includes a cooperative regeneration map and non-cooperative regeneration maps that define the thresholds of relatively low revolutions. The threshold of a predetermined low gear shift point is defined to be smaller than the thresholds of the gear shift points higher than the predetermined low gear shift point on the downshift side in the non-cooperative regeneration maps, and is defined to be smaller than the threshold of the predetermined low gear shift point on the downshift side in the cooperative regeneration map.

Abstract: In an X-ray dose management system, a dental radiograph device includes an imaging condition setter, an output information creator, and an information communicator that sends the output information to a wireless tag. An X-ray imaging element includes an X-ray image information obtainer and a wireless tag. An information reading device includes an output information reader and an information communicator that sends the read output information to an information terminal. The information terminal includes a patient information retriever that retrieves patient information from a patient information storage, a communicator that receives the output information, and an output information processor that records the output information and the patient information in association with each other in the patient information storage.
