摘要： A hydraulic valve lifter is held in the recess of the rocker arm swingably pivoted to the rocker shaft. An oil pressure chamber is formed between the lifter body and the plunger. An oil chamber to supply the oil to the oil pressure chamber is formed between the plunger and the recess. An oil supply path to supply the oil through the oil path of the rocker shaft communicates to the oil chamber. A return path is provided extending from the top of the oil chamber to a clearance between the inside of the rocker arm hole and the outside of the rocker shaft or to a clearance between the outside of the lifter body and the inside of the rocker arm recess. With this arrangement of the device, the air infiltrating the oil chamber can be discharged from the top of the oil chamber via the return path and the clearance, thereby preventing invasion of the air into the oil pressure chamber and ensuring normal functioning of the hydraulic valve lifter.

摘要： The present invention is to produce an aluminum nitride powder which is turned into a sintered body at a temperature of not more than 1600° C., thereby obtaining a sintered aluminum nitride in which the density and thermal conductivity are high and which can be properly used as a substrate material. Using a vapor phase reaction apparatus shown in FIG. 1, ammonia gas was fed from a reactor 2 heated at from 300 to 500° C. and maintained at that temperature by a heating section 1 via a feeding tube 4 while being regulated by a flow regulator 3. At the same time, while being regulated by the flow regulator 5, nitrogen gas containing an organic aluminum compound is fed via a feeding tube 6 to obtain an aluminum nitride powder. The aluminum nitride powder is subjected to a heat treatment at from 1100 to 1500° C. in a reducing gas atmosphere and/or an inert gas atmosphere to obtain an aggregate aluminum nitride powder. The aggregate aluminum nitride powder is subjected to a mechanical treatment to obtain an aluminum nitride powder in which the specific surface area value is not less than 30 m2/g and a ratio of an average particle diameter to a particle diameter in terms of the specific surface area is not more than 10.

摘要： NF.sub.3 gas containing N.sub.2 F.sub.2 as an impurity is purified by heating said NF.sub.3 gas at specified temperatures in a vessel the inner wall of which is coated with a strong and passive film of nickel flouride. According to this method, the rate of NF.sub.3 loss is low and the rate of removing N.sub.2 F.sub.2 is high. Therefore, when the NF.sub.3 gas thus purified is further purified with a known adsorbent, a highly pure NF.sub.3 gas can be easily and safely produced which is suitable for materials for semiconductor dry etching agents and the like.

摘要： A metal container to be filled with a halogen containing gas, with the inner surface processed with a polishing agent. The gas has a reduced purity decline by the increase of the water content or impurities from the inner surface of the container which is absorbed by the gas over the passage of time. The inner surface processing method is improved such that the value of dividing the area of the Si2s peak by the area of the Fe2p3/2 peak in the X-ray photoelectron spectrum of the gas container inner surface with the inner surface process with a polishing agent applied is 0.3 or less.
