Patent number: 7770486Abstract: In an automatic transmission, a shift lever is operable to move to one of a plurality of shift positions corresponding to ranges established as selectable options. The plurality of shift positions are each configured as one of a momentary position allowing the shift lever to automatically return to a home position and a retention position allowing the shift lever to be held therein. A return mechanism for causing the shift lever held in the retention position to return to the home position is provided. The return mechanism is enabled on one of conditions that the parking switch be turned on and that an ignition switch be turned off. In a manual transmission, a return mechanism for causing the shift lever held in a gear stage to return to a home position is provided, and the return mechanism is enabled on condition that an ignition switch be turned off.Type: GrantFiled: August 31, 2005Date of Patent: August 10, 2010Assignee: Honda Motor Co., Ltd.Inventors: Akio Morita, Yasushi Ohkawa, Yoshiharu Saito, Tomohiro Sakuraba, Atsushi Komatsu, Kotaro Hiramine, Shusaku Noguchi, Yoshinori Furusawa, Makirou Ishimoto

Patent number: 7722481Abstract: The invention provides a golf ball composed of a core, a cover having a plurality of dimples on an outside surface thereof, and an intermediate layer disposed between the core and the cover. The core has a deflection, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of at least 3.0 mm but not more than 5.0 mm. The intermediate layer is formed of a highly neutralized resin material, and has a Shore D hardness of at least 40 but not more than 60 and a thickness of at least 1.7 mm but not more than 4.0 mm. The number of dimples is at least 272 but not more than 348. The golf ball, through a combination of dimples which do not cause a loss of lift in the low-velocity, low-spin rate region of the ball trajectory and a low-spin construction, travels farther and is therefore beneficial for competitive use by both skilled and amateur golfers.Type: GrantFiled: February 19, 2008Date of Patent: May 25, 2010Assignee: Bridgestone Sports Co., Ltd.Inventors: Atsuki Kasashima, Atsushi Komatsu
