An EGR system includes an exhaust gas recirculation pipe recirculating exhaust gas flowing through an exhaust pipe into an intake pipe upstream of a compressor of a supercharger. A swirling flow generator generates a swirling flow of intake air and exhaust gas along an inner surface of the intake pipe in order to centrifugally separate foreign matters from the intake air and the exhaust gas. A foreign-matters-collecting chamber collects the centrifugally separated solid foreign matters therein. The separated solid foreign matters are discharged through a discharge opening and a discharge pipe.

A method of producing a primary amine by the hydrogenation of a nitrile in the presence of a hydrogenation catalyst. The hydrogenation catalyst contains at least one metal selected from the group consisting of nickel, cobalt and iron. Before use in the hydrogenation of nitrile, the hydrogenation catalyst is pretreated with at least one treating agent selected from the group consisting of hydrocarbons, alcohols, ethers, esters and carbon monoxide at 150 to 500° C.
摘要:
An object of the present invention is to provide a laser irradiation method and a laser irradiation apparatus for irradiating an irradiation surface with a linear beam having more homogeneous intensity by blocking a low-intensity part of the linear beam without forming the fringes due to the diffraction on the irradiation surface. In the laser irradiation, a laser beam emitted from a laser oscillator 101 passes through a slit 102 so as to block a low-intensity part of the laser beam, the traveling direction of the laser beam is bent by a mirror 103, and an image formed at the slit is projected to an irradiation surface 106 by a convex cylindrical lens 104.

It is an object of the present invention to provide a laser irradiation apparatus and a laser irradiation method for conducting a laser process homogeneously to the whole surface of a semiconductor film. A first laser beam emitted from a first laser oscillator passes through a slit and a condensing lens and then enters an irradiation surface. At the same time, a second laser beam emitted from a second laser oscillator is delivered so as to overlap the first laser beam on the irradiation surface. Further, the laser beams are scanned relative to the irradiation surface to anneal the irradiation surface homogeneously.

A straddle type vehicle includes a movable cover on a rear trunk space and a light assembly having a first light unit extending in a generally horizontal direction and a second light unit extending in a generally vertical direction. The assembly can also include two vertical light units, one positioned on the left side of the movable cover and the other positioned on the right side of the movable cover, and one horizontal light positioned below the movable cover. Connectors and fastening mechanisms can be utilized to connect the light units and movable cover of the assembly. In addition, the first light unit and the second light unit can both be a light-emitting diode (LED) light source.

There are provided a solid lubricant having an island-and-sea structure, which, with the sea phase strengthened, remains free of troubles such as chipping even in use under high load conditions, and a sliding member having the solid lubricant embedded therein. The solid lubricant comprises 1 to 10% by volume of a polyethylene resin, 20 to 60% by volume of a hydrocarbon-based wax, 10 to 60% by volume of melamine cyanurate, 5 to 15% by volume of a polyamide resin, and 2 to 10% by volume of a modified polyethylene resin. The sliding member has the solid lubricant embedded in pores or grooves formed in a sliding surface of the sliding member body.
摘要:
A decrease in voltage in a polymer electrolyte fuel cell comprising stack of unit cells caused by the temperature difference between the cells located at the ends and the other cells due to a differential in heat dissipation from end plates is prevented by controlling the cooling temperature of the cells closest to the end plates of the fuel cell without affecting the output voltage of the cells in the middle by not including a coolant flow channel in the conductive separator plate between at least one of the end plates and the unit cell located closest to the one of the end plates.
