Patent number: 9211445Abstract: The invention provides a golf ball having a core and a cover of one layer or a plurality of layers, the core being formed of a material molded under heat from a rubber composition which includes (A) a base rubber, (B) an organic peroxide, and (C) water and/or a metal monocarboxylate. The product P×E of the difference P (mol/m3) in crosslink density between the core surface and the core center, as measured based on a toluene swelling test, multiplied by the deflection E (mm) of the core when compressed under a final load of 1,275 N (130 kgf) from an initial load state of 98 N (10 kgf) is at least 28×102 mol/m3·mm.Type: GrantFiled: September 3, 2013Date of Patent: December 15, 2015Assignee: Bridgestone Sports Co., Ltd.Inventors: Tsuyoshi Nakajima, Yuichiro Ozawa

Patent number: 9197012Abstract: A vehicle charging port locking device has a charging port and a locking mechanism. The charging port has an engaged part that engage an engaging part of a charging connector for supplying power from an external power source to the charging port when in an engaged state. A restraining member is movably mounted between a locked state in which release of the engaged part is restricted by movement of the restraining member in a locking direction to prevent the engaging part from being released from the engaging state, and an unlocked state in which release of the engaging part is permitted by movement of the restraining member in an unlocking direction that is opposite the locking direction. The restraining member can be moved in the unlocking direction by operation of an exposed part that can be operated from beneath the hood of the vehicle.Type: GrantFiled: September 18, 2012Date of Patent: November 24, 2015Assignee: Nissan Motor Co., Ltd.Inventor: Tsuyoshi Nakajima

Patent number: 9178312Abstract: A charging port locking device is provided that basically includes a charging port and a lock mechanism. The lock mechanism achieves both locked and unlocked states by rotational movement of the restricting member. The restricting member is configured in the lock state with respect a reference line connecting a center of rotation of the restricting member and the center of width of the engaging portion as seen in a top view such that a top view area of the restricting member from the reference line in the rotational direction toward a restricting state is smaller than a top view area of the restricting member from the reference line in the rotational direction toward a non-restricting state.Type: GrantFiled: September 18, 2012Date of Patent: November 3, 2015Assignee: Nissan Motor Co., Ltd.Inventor: Tsuyoshi Nakajima

Patent number: 9178313Abstract: An electric vehicle charging port control device yields a locked state in which disengagement between an active-engagement part of a charging connector and a passive-engagement part of a charging port is restricted by a restricting member and an unlocked state in which disengagement is permitted. The restricting member is moved to in front of a predetermined position for yielding the locked state or the unlocked state by being energizingly driven by a motor. Before the active-engagement part and the passive-engagement part are engaged, the restricting member is moved in a locking direction, and subsequently in an unlocking direction.Type: GrantFiled: February 21, 2013Date of Patent: November 3, 2015Assignee: Nissan Motor Co., Ltd.Inventor: Tsuyoshi Nakajima

Publication number: 20150258388Abstract: In a multi-piece solid golf ball having a core, an intermediate layer and a cover, the ball and the intermediate layer have respective surface hardnesses which are set so as to satisfy a specific relationship. Also, the respective initial velocities measured for the core, a sphere composed of the core over which an envelope layer and the intermediate layer have been formed (intermediate layer-encased sphere) and the ball are set so as to satisfy a specific relationship. In addition, the hardness relationship between the surface and the center of the core has been adjusted in a specific range. This golf ball is able to exhibit an excellent flight performance not only when struck by mid head-speed golfers, but even when struck by low head-speed golfers, in addition to which it has both a good feel at impact and an excellent durability to repeated impact.Type: ApplicationFiled: January 23, 2015Publication date: September 17, 2015Applicant: BRIDGESTONE SPORTS CO., LTD.Inventors: Hideo WATANABE, Atsuki KASASHIMA, Tsuyoshi NAKAJIMA

Publication number: 20150229074Abstract: In a power supply connector, when defect is detected at the locking part by the defect detection means, sliding of the connector body and the grasping member with respect to the case is locked by the case lock mechanism; when defect is not detected at the locking part, the case lock mechanism is released and the connector body and the grasping member become slidable in a direction of nearly the same axis line with respect to the case. When the grasping member is slid forward with respect to the case in a state in which the case lock mechanism is released, the connector body becomes movable to the front with respect to the case. As a result, in the power supply connector, the connector in the power supply side is not connectable to the connector of the power reception side when there is a defect in the locking part.Type: ApplicationFiled: April 21, 2015Publication date: August 13, 2015Inventors: Tomoaki TORATANI, Naomi TAKAHASHI, Tsuyoshi NAKAJIMA
