Patent JP-H07280118-A (JP)
Title: Air valve
Inventor: KAMIJO YUKIO
IPC: F16K24/04
Filed: 1994-04-04
Abstract: PURPOSE:To provide an air valve having a simple structure, free from not only exhaust incapability at a normal service condition, but also exhaust incapability due to the upwash of a valve disc, and ensuring complete water discharge at a large volume intake process. CONSTITUTION:A bucket 33 having a large window hole 37 on the upper section of a surrounding wall and a small hole 39 on a bottom wall is laid in a valve box 3 having a large bore air port 21. Furthermore, the bucket 33 is internally provided with a floating valve disc 43 and a float 83, so as to be freely movable vertically. A small air hole 57 is drilled through the floating valve disc 43. In this case, the floating valve disc 43 opens and closes the large air port 21, while the float 83 opens and closes the small air hole 39. In addition, a vent hole 81 is separately drilled through the floating valve disc 43. As a result, at a large volume exhaust process, the air in the bucket 33 flows through the vent hole 81 and does not wash up the valve disc and the float 43 and 83. At a large volume intake process, water can be completely discharged from the small hole 39. When the volume of the stagnating air increases in a normal service condition, water level drops and the floating valve disc 43 is inclined to open the small hole 39.

A part of air having passed the rack 3 is discharged from a discharge port 9, and the remainder of the air is circulated in the stocker device. Thus, it is possible to facilitate the stock control and to enhance the quality of products.

Title: Sintered oil-containing roller chain bush
Inventor: SATOU TSUTOMU
IPC: F16G15/00
Filed: 1980-06-30
Abstract: PURPOSE: To obtain the roller chain bush having a specific composition and oil-containing ratio, a superficial hardened layer, high strength and excellent wear resistance.  
     CONSTITUTION: The sintered oil-containing roller chain bush comprising 1W7wt% Cu, 0.2W1.5wt% Cr, 0.1W 1wt% P, 0.5W1wt% C and the remainder of Fe and inevitable impurities, and having an oil-containing ratio of 5W35vol% and a superficial hardened layer. When the content of Cu is less than 1%, the effect of improving the strength of the bush cannot be obtained by its addition, and when the content is more than 7%, the deterioration of the hardness is remarkable. When each content of C and Cr is less than each lower limit of them, the effect of improving the hardness is insufficient, and when each content of C and Cr is more than each upper limit of them, the toughness is deteriorated. When the content of P is less than the lower limit, the effect of accelerating sintering, of rounding the shape of pores and of improving the strength by the addition of P is insufficient and, on the other hand, when the content of P is more than the upper limit, the brittleness of the bush results. When the oil-containing ratio is less than the lower limit, the lubricating properties of the bush cannot be ensured, and when the ratio is more than the upper limit, the strength and wear resistance are rapidly deteriorated. Further, the product is prepared by molding before sintering of raw material powder and further by the carbo-nitriding treatment, tempering treatment and impregnating treatment with oil in vacuum of the sintered body.
