The exhaust gas recirculation cooler is put adjacently between the exhaust gas recirculation valve and the bypass valve.

An electrolytic cathode consists of a solid copper hanger bar and a stainless-steel mother plate attached to a receiving groove in the underside of the hanger bar. In the preferred embodiment of the invention, the entire length of connection is welded, thereby establishing a large boundary surface for good electrical conductance. The solid hanger bar further includes a cladding of stainless steel wrapped over the copper bar and the upper portion of the mother plate, leaving only the ends of the copper bar exposed for electrical connection with conventional bus-bars. The lower edges of the cover are attached to the mother plate by a steel-to-steel weld that produces a strong and durable connection. The lateral edges of the cover are also connected to the copper bar by a conventional copper weld that completely seals the cover over the copper bar, thereby preventing contamination from the electrolytic solution. The cover is then welded to the mother plate and sealed around the copper bar. The heat produced by the welding process, which causes the steel cladding material to expand during welding, is used to improve the tightness of the fit between the cover and the copper bar as a result of the cover's shrinkage occurring during cooling.

Bu the present invention, an image heating apparatus is capable of ensuring durability and a flexible sleeve used for the image heating apparatus.

A cycle wheel and methods of manufacture of such a wheel. The cycle wheel has tensioned spokes between a hub and a rim and is equipped with a wheel fairing attached to the rim. The rim is provided with two grooves for receiving two radially outer edges of the wheel fairing, and the rim exerts, in the area of the two grooves, a centripetal force that blocks the radially outer edges of the wheel fairing in the grooves.

Disclosed are a method and an apparatus for removing methane from a gas which contains the methane at such a low concentration as not to be rendered into a combustible range with whatever ratio of air mixed therewith. In order to ensure satisfactory methane removal performance even in the coexistence of sulfur compound and in order also to provide stable methane removal performance for an extended period of time without performance deterioration even when the methane concentration varies significantly, the gas is fed to a heat exchanger for preheating and methane is exposed to an oxidation catalyst which oxidizes the methane through contact therewith. Then, the resultant gas is fed again to the heat exchanger for heat recovery through heat exchange with un-reacted gas. Further, the flow rate of gas to be treated is varied, according to a concentration of the methane contained in this treated gas.

An engine control apparatus for a work vehicle having a cooling fan or an auxiliary device driven by an engine. The engine control apparatus is capable of operating the work vehicle with the importance placed either on amount of work or fuel economy depending on the situation, and preventing the input of excessive traveling horsepower (or working horsepower), regardless of a selected work mode, to ensure durability of the traveling power train (or work machine drive equipment). Upon selection of a work mode by the work mode selection switch, a controller controls the engine to obtain a power curve selected from those selectable for the selected work mode can be obtained, based on the coolant temperature range and the selected work mode, so that the input torque transmitted to the traveling power train does not surpass the upper limit for the input torque (rated output).

The invention concerns new lubricants comprising a combination of a polyethylene oxide and an oligomer amide and an improved metallurgical powder composition comprising a major amount of an iron-based powder and a minor amount of this new lubricant. Furthermore, the invention concerns a method requiring low ejection force and low ejection energy for producing green products having high green strength. The method comprises the steps of mixing an iron-based powder and optional additives with the new lubricant and compacting the obtained powder composition.

A vehicle drive shaft includes: a first shaft portion, having a core shaft portion and a sleeve shaft portion coaxially arranged at one end, and a second shaft portion, having a spline hole portion and a second engagement protrusion at one end. A spline shaft portion and a first engagement protrusion are provided at distal ends of the core shaft portion and sleeve shaft portion. The spline hole portion is nonrotatably fixed to the spline shaft portion. The second engagement portion contacts the first engagement portion when a relative torsion allowable angle therebetween is larger than or equal to a gap. When the relative torsion allowable angle is smaller than the gap, torque is transmitted via the core shaft portion. When the relative torsion allowable angle is larger than or equal to the gap, torque is transmitted via not only the core shaft portion but also the sleeve shaft portion.

System, including methods, apparatus, and kits, for replacement of at least one surface region of a distal radioulnar joint using at least one prosthesis. In some embodiments, the system may provide restoration of normal, unconstrained biomechanics of the joint, which may preserve rotation and translation and ensure durability of the joint.

A battery unit mounting apparatus for an electric vehicle includes four or more fixing portions configured to be provided at the bottom of an electric vehicle and four or more corresponding portions-to-be-fixed on a battery unit. When the battery unit is raised toward the vehicle, the battery unit mounting apparatus causes each fixing portion to be engaged with the corresponding one of the portions-to-be-fixed. There is a first group, formed by three of the fixing portions and corresponding three of the portions-to-be-fixed, and a second group, formed by the remaining one or more of the fixing portions and the remaining one or more of the portions-to-be-fixed. The fixing portion and the portion-to-be-fixed in the second group are configured to be engaged with each other after the fixing portions and the portions-to-be-fixed in the first group are engaged.

A position shift control apparatus is provided which includes an electrical motor joined to an object through an output shaft and a torque transmission mechanism, a detent mechanism producing elastic pressure to hold the object at a target position, and a motor controller. When torque, which is created by the elastic pressure produced by the detent mechanism and acts on the output shaft during rotation of the motor, is opposite in orientation to that outputted by the motor, the motor controller determines the angular position of the motor, as sampled upon a change in an output from an output shaft position sensor, as a reference angular position of the motor for use in controlling the position of the motor, thereby resulting in a decrease in mechanical load on the detent mechanism and the torque transmission mechanism to ensure the durability and operation accuracy of the apparatus.
