    摘要: A decompression apparatus includes a plunger and a decompression shaft. The plunger is provided in a plunger hole formed in a cam shaft which is configured to move an engine valve of an internal combustion engine. The plunger is movable in the plunger hole between a decompression position in which the plunger opens the engine valve and a decompression cancel position in which the plunger does not open the engine valve. The plunger hole has a first opening which partially locates on a cam surface of a valve cam which is provided on the cam shaft. A first end portion of the plunger protrudes from the first opening to open the engine valve in the decompression position. The decompression shaft is provided in the cam shaft and configured to move the plunger between the decompression position and the decompression cancel position.

    摘要: Disclosed are a conductive thienyl derivative monomolecular film covalently bonded to a substrate surface and method of manufacturing the same, and a silicon compound comprising 3-thienyl groups (thiophene derivative) used for forming the conductive monomolecular film and a method of manufacturing the same. A monomolecular ultrathin film comprising 3-thienyl groups and silicon groups is formed in the invention. The silicon compound used for forming the film is provided by reacting .omega.-(3-thienyl)-1-alkene compound to a monosilane derivative compound, in which three out of four hydrogen atoms of monosilane are replaced with halogen or alkoxy groups, in the presence of a transition metal catalyst. A substrate is dipped and held in a nonaqueous solution of the above-noted compound, thus chemically bonding the monomolecular film to the substrate surface. Furthermore, a thienyl derivative ultrathin film is formed by the electrolytic or catalytic polymerization of the monomolecular film.
