Abstract: A photoelectric conversion element is disposed in each of a plurality of recesses of a support. Light reflected by the inside surface of the recess shines on the photoelectric conversion element. The photoelectric conversion element has an approximately spherical shape and has the following structure. The outer surface of a center-side n-type amorphous silicon (a-Si) layer is covered with a p-type amorphous SiC (a-SiC) layer having a wider optical band gap than a-Si does, whereby a pn junction is formed. A first conductor of the support is connected to the p-type a-SiC layer of the photoelectric conversion element at the bottom or its neighborhood of the recess. A second conductor, which is insulated from the first conductor by an insulator, of the support is connected to the n-type a-Si layer of the photoelectric conversion element.

Abstract: A power unit, including an engine and a transmission, is transversely arranged in a vehicle with a crankshaft arranged parallel to a traveling direction of the vehicle. Looking at a crankcase from the front, a camshaft is arranged to one side of the crankshaft. A balancer shaft is also located on the one side of the crankshaft and coaxailly drives an oil pump. The transmission and an oil tank are arranged on the opposite side of the crankshaft. The crankshaft includes a crank sprocket which drives the cam shaft via a cam chain and a cam sprocket provided on one end of the cam shaft. The cam sprocket and the oil pump are arranged on either side of a balancer attached to the balancer shaft. The power unit arrangement allows for an increase in the potential capacity of the oil pump of a dry sump type lubrication system without causing an increase in the size of a crankcase.
