IPC: C21D7/06
Filed: 1992-05-28
Abstract: PURPOSE:To remarkably improve the durability of a valve spring. CONSTITUTION:A valve spring coiled with an oil temperted wire is applied to a low temp. carburizing and nitriding treatment, thereafter subjected to a shot peening using a hard shots having 650 to 850Hv Vickers hardness. In a valve spring X subjected to shot peening by hard shots having 650 to 850Hv surface hardness above that of a valve spring in which the maximum hardness on the surface is regulated to 600 to 800Hv by the low temp. carburizing and nitriding treatment, the residual compressive stress on the surface is increased by about -30 to -60Kgf/mm<2> comparted with a valve spring (x) subjected to shot peening by ordinary shots having 500 to 600Hv hardness as shown in (A). Consequently, its durability is improved by 2 to 10 times.

Title: Biological treatment of waste water containing organic substance
Inventor: UCHIMI MAMORU
IPC: C02F3/30
Filed: 1982-09-18
Abstract: PURPOSE:To contrive to make various devices small in size, to simplify operation and to contrive the retrenchment of a running cost and the shortening of a disposal time, by treating high conc. waste water as such without diluting it with diluting water. CONSTITUTION:Waste water (a) is sequentially sent through a conditioning tank 1, an anaerobic tank 2, an intensive aeration tank 3, a separation means 4, an aeration tank 5 and a precipitation tank 6, while sludge separately precipitated in the tank 6 is circulatorily returned through a reaeration tank 7 to the inlet openings of the tanks 3, 5. In this circulating system for waste water disposal, by mixing formed aerobic sludge with anaerobic sludge formed by the treatment of high conc. waste water under an anaerobic condition, said high conc. waste water is biologically treated. Consequently, there is no necessity for diluting high conc. waste water as a conventional manner. Thus, it is possible to make devices such as the aeration tank small in size, operation can be simplified, and the amount of aerating air in the aeration tank can be curtailed, so that power expense for a blower is alleviated to retrench a running cost.
