The large-aperture-ratio inner-focusing telephoto zoom lens has four groups of lens pieces, namely, the 1st lens group of positive refractive power, the 2nd lens group of negative refractive power, the 3rd lens group of positive refractive power, and, the 4th lens group of positive refractive power arranged in series on the basis of “closer to a subject first,” and that has the 2nd and 3rd lens groups moved along the optical axis to vary a magnification power. In such a telephoto zoom lens, the 1st lens group includes the leading subgroup of lens pieces or foremost lens subgroup G1F and the trailing subgroup of lens pieces or rear lens subgroup G1R where the G1F has two of a concave lens piece and a convex lens piece cemented into a single piece of composite lens while the G1R has a composite lens of one concave lens piece and two convex lens pieces in series. The rear lens subgroup G1R in the 1st lens group is moved along the optical axis for the focusing, and the telephoto zoom lens has an optical property that satisfies requirements as follows:	09-04-2008

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
20090183497	EXHAUST GAS PURIFYING APPARATUS - In a hybrid vehicle equipped with an exhaust gas purifying apparatus, when a gasoline engine stops, an exhaust gas passage is closed by a pair of upstream-side and downstream-side throttle units to form an accommodation space. 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

20080290071	METHOD FOR DETERMINING WIRE SUPPORTING POINT IN WIRE-CUT ELECTRICAL DISCHARGE MACHINE AND MEASURING MEMBER FOR PRACTICING THE SAME - A measuring member having a conical section with a known vertex angle is inserted into a guide hole through a trumpet-shaped inner surface (wire guiding surface) formed by rotating a convex about the axis of the guide hole. Then, the surface of the conical section of the measuring member stops at the point of tangential contact with the inner surface. The point at which the wire electrode is supported, measured from the reference wire supporting point, can be determined from the height of a specific point on the measuring member in the stopped state and the distance from this specific point to the vertex of the conical section of the measuring member.	11-27-2008

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
