Patent number: 7749133Abstract: A driving device of the invention has a clutch 40 and a continuously variable transmission 50. The clutch 40 couples and decouples a rotating shaft 24 or an output shaft of a motor 30 with and from a driveshaft 22. The continuously variable transmission 50 has an input shaft connected to the rotating shaft 24 and an output shaft connected to the driveshaft 22 via a gear mechanism 52. A spring 36 is attached to a rotor 31 of the motor 30 to apply a pressing force and cause the clutch 40 to couple the rotating shaft 24 with the driveshaft 22 in response to a relatively small output torque of the motor 30. With an increase in output torque of the motor 30, a thrust force produced in the motor 30 moves the rotating shaft 24 against the pressing force of the spring 36 to cause the clutch 40 to decouple the rotating shaft 24 from the driveshaft 22. The output torque of the motor 30 is then transmitted to the driveshaft 22 with a gear change of the continuously variable transmission 50.Type: GrantFiled: August 30, 2006Date of Patent: July 6, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tomokazu Yamauchi, Shoichi Sasaki

Patent number: RE40899Abstract: In a card connector of the present invention, an eject plate has a push-moving portion, an engaging portion and a spring portion, and can be switched to two positions by a heart cam. In an electric connecting state of the card and the connector, the eject plate is set to a second position, and its engaging portion is engaged with a notch formed in the card, and the release of the engagement is prevented by a guide wall, and no card can be pulled out even when strong pulling-out force is applied to the card (full lock). When the eject plate is moved from the second position to a first position by a tension spring, the card is pushed out by the push-moving portion. The engaging portion is also engaged with the notch of the card in this first position, but the release of the engagement is allowed by the wall portion, and the card can be pulled out by elastically deforming the spring portion (half lock).Type: GrantFiled: August 10, 2006Date of Patent: September 1, 2009Assignee: J.S.T.
