Abstract: There is disclosed a molding compound for making an article including a cellulose fiber, which is prepared by mixing a cellulose fiber added with at least starch, water and a long chain fatty acid salt of a non-alkali metal. There is also described a method for molding an article including a cellulose fiber by employing the above compound and, further, a mold for molding an article including a cellulose fiber with a cavity formed by a stationary side and a movable side which is used therefore.

Abstract: A lubricating oil pump device of an engine comprises an upper and a lower pump case and a rotary pumping mechanism of the internal-gear, one-tooth difference type housed within a housing formed between the upper and lower pump cases. Both the pump cases have oil reserving oil sumps formed therein, thereby to reserve some oil in the pump device even when the engine is stopped for a long period. Then, when the engine is restarted and the pumping mechanism operates, the oil thus reserved in the oil sumps is contacted by the moving pumping mechanism and is induced out to form oil films on the surfaces of the pump cases and of the pumping mechanism. Thus instant lubrication and sealing for effective suction are assured.
