摘要:
Provided is a method of producing an anode material for a non-aqueous electrolyte secondary battery having battery characteristics equivalent to those of a conventional product by simpler production steps than those of a conventional method.A thermally-polymerized petroleum based or coal based pitch is cooled to the softening point or below so that the pitch is solidified to obtain a solidified pitch. The solidified pitch is ground to form a fine pitch powder having an average particle size (median size) of 60 μm or smaller. Then, the fine pitch powder is compression molded at a pressure of 20 to 100 MPa or 0.1 to 6 MN/m to form a porous compression molded pitch. The porous compression molded pitch is subjected to infusibilization treatment.

摘要:
A production management method in a production system for semiconductor devices uses processing progress information for each of the plural number of manufacturing apparatus as the basis for performing start allocation of a plural number of next start product groups. When the state of progress has reached a certain stage and is close to the end, a product group of the same type as that which a manufacturing apparatus is processing from amongst start standby product groups is determined as the object of same type priority allocation. A link is made beforehand between that product group and a manufacturing apparatus for which that processing is about to end, and a product group that is an object of same type priority allocation to a manufacturing apparatus that is processing products of that same type, is not started by a manufacturing apparatus that is processing a product of a different type even if that manufacturing apparatus finishes its processing of a product of that different type earlier.
摘要:
A crankshaft of a V-6 internal combustion engine is provided with first and second end balance weights located at the front and rear end sections thereof. The crankshaft is further provided with first and second middle balance weights located near the first and second end balance weight, respectively, and a central balance weight located at the central section thereof, thereby establishing dynamic balance even between the adjacent main bearing journals of the crankshaft.
