Patent number: 6707180Abstract: A coolant inlet and a coolant outlet are opened on an inner surface enclosing an inner space of a rotation object. The coolant inlet and the coolant outlet are located on a rotation axis and face each other. A main-stream which flows straightly along the rotation axis from the coolant inlet to the coolant outlet is generated in a central space of the inner space. Therefore, a resistance about the coolant stream is small. In addition, a sub-stream which circulates in a radial direction is generated in a peripheral space around the central space. By generating a contact between the main-stream and the sub-stream, it is possible to obtain high performance of cooling.Type: GrantFiled: December 19, 2002Date of Patent: March 16, 2004Assignee: Nissan Motor Co., Ltd.Inventors: Noboru Hattori, Masakazu Kobayashi

Patent number: 6296593Abstract: A generator (4) is combined with drive wheels (8) of a vehicle, and the output of an engine (2) is transmitted to the drive wheels (8) under an engaging force of an electromagnetic clutch (3) in response to an energizing current. During a predetermined deceleration state, a braking force is applied to the drive wheels (8) and a battery (15) is charged by the generator (4) which performs regenerative power generation. At this time, the controller (16) supplies a weak energizing current to the electromagnetic clutch (3) so as to put the clutch (3) into a partially engaged state. A sensor (29) detects the output rotation speed of the clutch (3). When the output rotation speed of the clutch (3) is high, the controller (16) decreases the energizing current so that the rotational resistance of the electromagnetic clutch (3) is reduced.Type: GrantFiled: October 25, 1999Date of Patent: October 2, 2001Assignee: Nissan Motor Co., Ltd.Inventors: Yuuji Gotou, Noboru Hattori
