In a drive system, there is provided a waste heat recovering device forming a Rankine cycle by an evaporator for heating water with waste heat of an internal combustion engine to generate high-pressure vapor, the internal combustion engine being connected to a transmission, a displacement-type expander for converting high-pressure vapor generated by the evaporator to an output with constant torque, a condenser for liquefying low-pressure vapor discharged from the expander, and a feed pump for supplying water liquefied by the condenser to the evaporator. The expander is connected to a power generator/motor via a planetary gear mechanism, and the expander is connected to an output shaft of the internal combustion engine via the planetary gear mechanism and a belt-type continuously variable transmission. A change gear ratio of the belt-type continuously variable transmission is controlled such that a rotational speed of the internal combustion engine and a rotational speed of the expander are matched with each other and are transmitted to the transmission. Hence, it is possible to effectively drive the driven portion by using the output of the expander of the waste heat recovering device.

摘要:
Disclosed herein is a process for forming an amorphous alloy material capable of showing glass transition, which comprises holding the material between frames arranged in combination; and heating the material at a temperature between its glass transition temperature (Tg) and its crystallization temperature (Tx) and, at the same time, producing a pressure difference between opposite sides of the material, whereby the material is brought into close contact against a forming mold disposed on one side of the material. As an alternative, the forming mold is brought into close contact against the amorphous material in a direction opposite to the pressing direction for the amorphous material. By the above processes, precision-formed products of amorphous alloys can be manufactured and supplied at low cost. These formed amorphous alloy products can be used as mechanical structure parts and components of high strength and high corrosion resistance, various strength members, electronic parts, arts and crafts, original printing plates, or the like.
摘要:
Provided is a novel palladium catalyst capable of efficiently purifying carbon monoxide (CO) and total hydrocarbons (THC) under a fuel-rich atmosphere even when palladium (Pd) is used as a catalyst active component. Proposed is a palladium monolayer catalyst for an exhaust gas from a saddle-riding-type vehicle, which is an exhaust gas purification catalyst for a saddle-riding-type vehicle to be installed in an exhaust gas passage in an internal combustion engine. The palladium monolayer catalyst includes a substrate, and a catalyst layer that has the form of a monolayer and contains palladium acting as a catalyst active component, an inorganic porous body acting as a catalyst carrier, ceria (CeO2) particles acting as a promoter component, and barium.

摘要:
A lightweight and high-strength valve lifter is excellent in wear resistance and sliding properties. The valve lifter is made of a titanium alloy having a hardened layer on the top surface thereof, on which a cam is caused to slide. The hardened layer is composed of an α-case and an oxygen diffusion layer under the α-case. The α-case 22 is formed in a thickness of not less than 3 μm and not more than 15 μm. The oxygen diffusion layer has a thickness of not less than 10 μm. The hardened layer on the top surface of the valve lifter is formed by oxidation treatment in a furnace at a temperature of not less than 600° C. An outermost oxide layer 21 formed on the α-case as a result of the oxidation treatment is removed.
