Patent number: 10916902Abstract: [PROBLEMS] To provide a coaxial connector assembly maintaining a characteristic impedance and allowing floating. [SOLUTION] First to third coaxial connectors 10 to 30 are provided. A second center conductor 23 of the second coaxial connector 20 has a second shaft portion 23A held by a second dielectric body 22, a right columnar one-end-side contact portion 23B to be fitted in a first receiving portion 13B of the first coaxial connector 10, and the other-end-side contact portion 23C to be fitted in a third center contact portion 33B of the third coaxial connector 30. The one-end-side contact portion 23B is larger than the outer diameter of the second shaft portion 23A.Type: GrantFiled: September 12, 2019Date of Patent: February 9, 2021Assignee: HIROSE ELECTRIC CO., LTD.Inventor: Kentaro Maki

Patent number: 8825248Abstract: Disclosed is an information terminal for electric-powered vehicles or a cruise controller therefor to provide a driver with a traveling method that can shorten a total required time to a destination including a charging time. An information terminal for electric-powered vehicle configured to calculate a required time for the vehicle to travel a route from a current position to a destination in accordance with map information, includes: route setting means that searches for a route to the destination; recharging place setting means that sets a charging place on a way of the route to the destination set by the route setting means; and charging facility information acquisition means that acquires information on the charging place set by the recharging place setting means. A recommended vehicle speed or a vehicle speed range including the recommended vehicle speed at a section to the charging place is calculated.Type: GrantFiled: July 3, 2012Date of Patent: September 2, 2014Assignee: Clarion Co., Ltd.Inventors: Kentaro Maki, Takashi Okada, Masao Sakata
