摘要:
In the specific embodiments described herein, the charge drop resulting from fatigue in an electrophotographic process using an a-Se:H photosensitive member is reduced by a stabilization exposure carried out for one to three cycles prior to use of the member for image formation. Longer wavelength light may be used for the stabilization exposure and shorter wavelength light may be used for the imaging and discharge steps.

Disclosed is an production method for plasma chemical vapor deposition (CVD) of amorphous silicon films providing improved throughput and film yield. According to the present invention, a glow discharge is generated in a reaction chamber containing a gaseous silicon-containing compound, such as monosilane (SiH.sub.4) or tetraflourosilane (SiF.sub.4), by the imposition of an electric field between a pair of spaced-apart electrodes within the chamber. The electric field is established by connecting an appropriate DC or high frequency driving voltage to one of the pair of electrodes and ground potential to the other. In the case where a high frequency driving voltage is used, connection to the driven electrode is made through a coupling capacitor, and the frequency of the driving voltage is selected such that a DC potential develops between the pair of electrodes. Substrates on which amorphous silicon films are to be deposited are positioned adjacent to each one of the electrodes, and the connections for the driving voltage and ground to the electrodes are periodically reversed during film deposition. In an alternative embodiment of the invention, multiple pairs of electrodes are arranged within the reaction chamber.

A general-purpose engine equipped with a rollover detection device for a general-purpose engine that is used for driving a driving unit such as a rammer. An oil pan is provided in a crankcase of an engine main body, and lubricating oil is supplied to a lubrication part of the engine main body by an oil pump. A suction port of a lubricating oil intake part that guides the lubricating oil to an intake port of the oil pump is provided in a substantially central part in front-rear and left-right directions of the oil pan. Therefore, even when the general-purpose engine rolls over in the front-rear or left-right direction, the lubricating oil does not enter the lubricating oil intake part. Detecting whether or not the lubricating oil is discharged from the oil pump allows detection of a rollover of the general-purpose engine.
