20090183496 | EXHAUST GAS PURIFYING APPARATUS - A throttle unit placed in an exhaust gas passage controls an opening-ratio of each of first and second valve members to control a gas-flow sectional area of the exhaust gas passage. When the temperature of a three-way catalyst is low, the throttle unit introduces the exhaust gas flow into a part of an outer-periphery of the three-way catalyst. This control can rapidly increase the temperature of the three-way catalyst from an early period of starting an internal combustion engine within a short period of time. The throttle unit increases the gas-flow sectional area of the exhaust gas passage according to increasing the temperature of the three-way catalyst. When the three-way catalyst reaches its activation temperature, the throttle unit instructs the first and second valve members to fully open. This decreases a pressure loss of the exhaust gas because the exhaust gas is supplied into the entire of the three-way catalyst. | 07-23-2009 |

A pressure reduction unit reduces a pressure of the closed accommodation space where a three way catalyst is placed. The exhaust gas around the three way catalyst in the closed accommodation space does not leak into either an outside atmosphere side or into the gasoline engine side. Reducing the pressure in the closed accommodation space decreases heat conduction through the exhaust gas toward the outside. It is thereby possible to prevent the temperature drop of the three way catalyst and to keep the three way catalyst at a temperature of not less than its activation temperature for a long period of time even if the gasoline engine stops. | 07-23-2009 |

20100199810 | FASTENING TOOL - When bolts are fastened to tack a door to a car body by means of a conventional impact wrench, the shavings stick to the surface of the door or car body, thereby to cause the poor coating quality such as a seeding when the inter-coating or finish-coating is performed in the coating procedure. An impact wrench provided is a fastening tool for fastening a bolt gripped by a socket, in a nut. The impact wrench includes a suction cover for covering the surroundings of the socket, and a suction port capable of sucking the atmosphere in the portion covered with the suction cover, and is constituted such that the atmosphere in the suction cover is sucked through the suction port to recover the shavings left at the time of fastening the bolt. This constitution makes it possible to prevent the shavings from being scattered to the surroundings. When the door is temporarily attached at the coating step to a car body, the poor coating quality such as the seeding, as might otherwise be caused by the shavings stuck to the surface of the car body or door, can be prevented and improved. | 08-12-2010 |
