| 20100045636 | ERROR DETECTING APPARATUS AND METHOD, AND COMPUTER PROGRAM - An error detecting apparatus includes: a reading device obtaining an image read signal by reading a two-dimensional code pattern, which includes information blocks having information and boundary patterns, the information pattern including first/second pattern images (PIs) corresponding to first/second PIs, respectively, in each reading range corresponding to a size ≧ a size of the information block. A reference point detecting device detects an intersection in the boundary pattern, as a block reference point (P, Q), from the image read signal; an extracting device extracts the first/second information data (ID), based on one portion of the first PIs and the second PIs belonging to an ID extraction area determined according to a position of the block reference point; an error detecting device detects whether any error in the extracted first/second ID based on another portion of the first/second PIs belonging to another area other than the ID extraction area. | 02-25-2010 |

| 20080271617 | Stencil printing machine with a plurality of drum units and method of controlling the same - A controller reads out image data of an area frame that a user has drawn on an original and accurately extracts the area frame by removing noise from the read-out image data to divide image data of an area outside the area frame and image data of an area inside the area frame into separate stencils, according to a separation program. It is therefore possible to execute a separation process desired by the user without increasing costs and man-hours and with easy operations not making the user feel troublesome. | 11-06-2008 |

| 20090169963 | Fuel Cell System, Fuel Cell Valve System, and Fuel Cell Gas Supply Device - A fuel cell system includes a first shut valve capable of shutting off a gas flow in a gas path where a fuel cell gas flows; and a second shut valve arranged more towards the downstream side of the gas flow than the first shut valve, and capable of shutting off the gas flow. In each of the first shut valve and the second shut valve, sealing is performed by intimate contact between a movable member and a seal member and a gas pressure supplied from the upstream applies a force to the movable member to bring it into intimate contact with the seal member. A deformation degree by an external force of the same intensity is set greater in the seal member of the second shut valve than in the seal member of the first shut valve. | 07-02-2009 |

| 20100151360 | ONBOARD FUEL CELL SYSTEM AND METHOD OF DISCHARGING HYDROGEN-OFF GAS - Consumed hydrogen-off gas is discharged from a fuel cell via a hydrogen-off gas exhaust flow passage. Consumed oxygen-off gas is discharged from the fuel cell via an oxygen-off gas exhaust flow passage. The oxygen-off gas flowing through the oxygen-off gas exhaust flow passage and the hydrogen-off gas flowing through the hydrogen-off gas exhaust flow passage are mixed and diluted in a mixing portion. The gases mixed in the mixing portion flow into a combustor via a gas-liquid separator. The combustor, which includes a platinum catalyst, causes hydrogen contained in the mixed gases to react with oxygen by combustion and further reduces the concentration of hydrogen contained in the mixed gases. The mixed gases whose concentration of hydrogen has been reduced by the combustor is discharged to the atmosphere. | 06-17-2010 |

| 20090014089 | Valve, Valve Controller, and Fuel Cell System - Provided are a valve being able to adjust a flow rate of fluid out of a tank with a high accuracy, a valve controller, and a fuel cell system. The valve is configured to adjust the flow rate of fluid to the secondary side. The valve is disposed on the tank so that the secondary side is a discharge side for fluid from inside the tank. The valve is configured to adjust the flow rate of fluid from the tank by a duty control. | 01-15-2009 |
| 20090032318 | FUEL CELL VEHICLE - A high-pressure tank is disposed on a rear side of a vehicle, a fuel cell for consuming a fuel gas in the high-pressure tank is disposed on a front side of the vehicle, and a supply pipe for supplying the fuel gas to a fuel cell from the high-pressure tank is provided. The supply pipe is housed in a tunnel part formed in a shape projecting toward the vehicle interior side at the bottom face of the vehicle in a front-rear direction. | 02-05-2009 |
| 20090078706 | High-pressure tank - There is disclosed a high-pressure tank capable of appropriately discharging high-pressure gas. The high-pressure tank is mounted on a mobile body, stores the high-pressure gas, and includes a plurality of gas discharge means for discharging the high-pressure gas from the high-pressure tank. The gas discharge means are disposed at opposite sides of the high-pressure tank in a longitudinal direction. The gas discharge means can each have a path through which the inside of the high-pressure tank communicates with the outside thereof, and a manual valve including a manual operating section for opening and closing the path by a manual operation. | 03-26-2009 |
| 20090267014 | Fluid On-Off Valve Device - A check valve (fluid on-off valve device) capable of attaining high sealability in either case where a differential pressure is high or low, comprises a valve body assembly (valve body) contacting and separating from a valve seat portion for communicating and blocking a fluid passage. The valve body assembly comprises a valve body, a low-pressure seal portion constituted out of soft material and a high-pressure seal portion constituted out of harder material than the low-pressure seal portion. In blocking a fluid passage, when a differential pressure between an upstream path and a downstream path in the fluid passage is relatively low, the low-pressure seal portion comes into close contact with a protrusion to block the fluid passage, while when the differential pressure is relatively high, the low-pressure seal portion is compressively deformed by the differential pressure and the high-pressure seal portion comes into close contact with the valve seat body, thus blocking the fluid passage. | 10-29-2009 |
| 20100320217 | BACKUP RING AND TANK WITH THE SAME - Provided is a backup ring capable of reinforcing a seal member such as an O-ring, preventing extrusion of the seal member, and preventing the backup ring from suddenly opening in its circumferential direction, thereby improving the sealability; and a tank equipped with such a backup ring is also provided. A backup ring is formed into a ring body by making a first cut surface and a second cut surface come into contact with each other wherein the cut surfaces are formed by cutting the backup ring. An engagement protrusion is formed on the first cut surface, while an engagement recess capable of engaging with the engagement protrusion is formed on the second cut surface so that the engagement protrusion can be attached to or detached from the engagement recess. When the engagement protrusion and the engagement recess engage with each other, the first cut surface is in contact with the second cut surface, so that circumferential movement of the second cut surface relative to the first cut surface is prevented. | 12-23-2010 |

| 20080202603 | Pressure Reducer - A pressure reducer includes a piston slidably accommodated in a cylinder to define a decompression chamber and a pressure adjusting chamber. A seal member includes an elastic member and a sliding portion. The sliding portion is pressed by the elastic member such that the sliding portion slides on an inner circumferential surface of the cylinder. An annular member is located on an outer circumferential surface of the piston and between the seal member and the pressure adjusting surface. The annular member is pressed against the inner circumferential surface of the cylinder with a force that is less than a force with which the sliding portion is pressed against the inner circumferential surface of the cylinder. Thus, the pressure reducer prevents the piston from being moved by an excessive amount with highly accurately adjusting pressure. | 08-28-2008 |
