    摘要： In order to provide an automated warehouse having high space utilization efficiency, high floor area utilization efficiency, and high loading/unloading efficiency and a method of managing the warehouse, a transfer unit is placed above a stocking area, a holding unit of the transfer unit can move three-dimensionally, and an elevating unit of the transfer unit, which holds a stock object and raises/lowers it, raises/lowers a stock object without making it roll. This transfer unit holds a stock object in a loading area, and transfers the loaded stock object over stock objects stored in the stocking area. The transfer unit then lowers this stock object from above and stacks it flat or on another stock object. When an object is to be unloaded, the transfer unit holds the stock object from above and transfers it to an unloading area through the air.

    摘要： Disclosed herein is a new method for continuous heat treatment to be applied to the production of oil tempered steel wires for springs having high strength and high toughness to meet the requirement for weight reduction.The heat treatments are applicable to a medium carbon low alloy spring steel which does not undergo martensitic transformation substantially upon oil hardening alone. It comprises performing two-step accelerated hardening consistin of oil hardening and immediately following water hardening and subsequently performing tempering. The medium carbon low alloy steel is one which consists 0.40-0.65% carbon and Si and Mn as essential components and further at least one species of Cr, Ni, Mo, and V, and have the chemical composition corresponding to and Mf point lower than 80.degree. C. (preferably 10.degree.-70.degree. C.). It is desirable that the oil be wiped from the steel wire after the oil hardening and before the water hardening.
