Abstract: To present a control method for saving power capable of saving power in such a machine as a turret punch press, and preventing generation of noise due to operation of main motor of hydraulic unit while processing job is not done, being applied in such a machine as a metal cutting machine designed to be driven by feeding electric power to a main motor and servo amplifiers of individual axes, with the electric power supplied in both main motor and servo amplifiers of individual axes, it is designed to cut off power supply circuits to the main motor and servo amplifiers of individual axes, on the condition that the machine is not operated for processing and that the no-operation state continues for a prescribed time.

Abstract: An improved method for the production of a laminated product of porous materials, which comprises applying a two-part aqueous adhesive comprising(A) a main composition comprising a water-soluble urethane prepolymer and a polyurethane rubber, and(B) a curing composition comprising water and optionally a conventional curing agent,to the surface of at least one of materials to be adhered, wherein at least one of the materials to be adhered is a porous material, and piling up the materials and then pressing. Said two-part aqueous adhesive has excellent adhesion, particularly initial adhesion, and hence can give the desired laminated products by pressing the piled materials for a very short period of time, and the laminated products have excellent feeling and handling and are useful as a material for seats in automobiles, offices, etc., carpets, cushions, and the like.
