| 20100164225 | WATERPROOF CONNECTING STRUCTURE FOR PIPE - A waterproof connecting structure for a pipe for connecting an intake passage of an internal combustion engine and an external gas detector to convey gas into the intake passage. The structure includes a connecting space to which the pipe is connected and a partition wall formed between the intake passage and the connecting space. The connecting space has a larger diameter than the pipe. The partition wall includes an elongate hole for placing the interior of the intake passage and the connecting space in fluid communication. This configuration prevents intrusion of droplets drifting in through intake air and allows a high degree of freedom for location of the pipe. | 07-01-2010 |

| 20100227727 | DIFFERENTIAL GEAR DEVICE - A differential gear device includes a case in which a housing portion is formed, and which rotates around a rotation center line; a first protruding portion that is located at a position away from the rotation center line, and protrudes from an inner surface of the case toward the rotation center line, wherein the first protruding portion tapers in a direction from the inner surface of the case toward the rotation center line; a first gear that is provided around the first protruding portion, and that is rotatable; a second gear that engages with the first gear, and that is connected with a first output shaft; and a third gear that engages with the first gear, and that is connected with a second output shaft. | 09-09-2010 |
| 20100234160 | DIFFERENTIAL GEAR DEVICE - A differential gear device includes a case that rotates around a rotation center line; a first protruding portion protruding from an inner surface of the case toward the rotation center line; a rotatable first gear provided around the first protruding portion; and a second gear including a ring-shaped base portion, and a connection portion formed on an inner peripheral surface of the base portion, and connected to an output shaft, wherein the second gear engages with the first gear. One end of the base portion, which is located in the case at a position inside an opposite end of the base portion in an axial direction of the output shaft, is located in a region that is located directly ahead of the first protruding portion in a direction in which the first protruding portion protrudes. | 09-16-2010 |
| 20100261569 | FRONT DIFFERENTIAL FOR A VEHICLE - A front differential for a four wheel drive vehicle, includes: a switching mechanism that switches the vehicle between rear-wheel drive and front- and rear-wheel drive by selectively interrupting or allowing the transmission of power between one of a pair of side gears and one of a pair of front wheels; and an urging mechanism that urges at least one of the pair of side gears in a drive shaft axial direction toward at least one of the front wheels. | 10-14-2010 |

| 20100167149 | FUEL CELL SYSTEM - A temperature sensor | 07-01-2010 |
| 20120015269 | FUEL CELL SYSTEM - Provided is a fuel cell system that performs a warm-up operation by reducing a supply of oxidant gas to a fuel cell, the system having: a fuel cell; and a control unit that regulates amounts of oxidant gas and fuel gas supplied to the fuel cell and controls a power-generation state of the fuel cell. During the warm-up operation with a reduced supply of oxidant gas to the fuel cell, the control unit varies a voltage of the fuel cell for a short period of time to obtain current-voltage characteristics which indicate a relationship of an output voltage and an output current of the fuel cell, calculates an effective catalyst area of the fuel cell based on the obtained current-voltage characteristics, and determines whether the warm-up operation of the fuel cell can be stopped or not based on the calculated effective catalyst area. | 01-19-2012 |
| 20120045706 | COOLING SYSTEM AND METHOD OF A FUEL CELL - A cooling system of a fuel cell is provided with a main cooling flow passage and a bypass cooling flow passage which is arranged parallel with the main cooling flow passage and diverts the same coolant, as flow passages through which coolant flows. A radiator and a coolant circulation pump and the like are arranged in the main cooling flow passage. Coolant from the main cooling flow passage enters the bypass cooling flow passage and reaches a second heat exchanger via a case of a motor of an ACP and the like. At the second heat exchanger, heat exchange is also performed with a supply gas flow passage, after which the coolant returns to the main cooling flow passage. The manner in which the coolant is distributed can be changed depending on where the coolant is diverted from the main cooling flow passage and the arrangement of the circulation pump. | 02-23-2012 |

| 20080245320 | Water-Cooled Engine and Cylinder Block Thereof - A cylinder block has a cylinder bore and a water jacket provided about the cylinder bore. The cylinder block is divided at the water jacket into a cylinder liner portion and a cylinder outer wall portion. The cylinder liner portion has a wall defining the cylinder bore. The cylinder outer wall portion surrounds the wall of the cylinder liner portion, thereby defining the water jacket between the cylinder outer wall portion and the wall of the cylinder liner portion. The cylinder liner portion includes an upper deck portion integrally formed with the cylinder liner portion. The upper deck portion contacts the cylinder head assembled to the cylinder block. The cylinder outer wall portion has a top surface that functions as a receiving surface that contacts and supports the upper deck portion. | 10-09-2008 |
| 20090071570 | Pour Connector and Pour Port Structure of Liquid Container - A guide piece having a guide surface is integrally formed in a body portion so as to protrude from an inner circumferential wall surface of a pour passage toward the center thereof. A gas guide portion is formed in a portion of the pour passage in which the guide piece is formed. The gas guide portion is defined by a lower surface of the guide piece and the inner circumferential wall surface of the pour passage. When the pour connector is connected to the pour port of the liquid container to use the same, a projection edge of the guide piece is positioned below its base portion on the inner circumferential wall surface of the pour passage in the gravitational direction, so that the liquid poured into the pour passage can flow toward the center while it is guided by the guide surface, whereas the gas guide portion is positioned above the projection edge of the guide piece in the gravitational direction, so that gases in the container can be discharged from circumferential ends of the gas guide portion in a direction opposite to the pour direction. | 03-19-2009 |
