    摘要: A method for forming conductor layers of substrates for mounting LSIs and the like and a fabrication method of multilayer substrates are disclosed. These methods comprise steps of forming a metal underlayer having a shape similar to that of a conductor pattern on the substrate, forming an insulation layer over portions of the substrate which are not covered by the metal underlayer, and disposing a plating layer on the metal underlayer by carrying out electroless plating while using the insulation layer as the resist and thereby forming conductors. As compared with a conventional conductor layer forming method, the number of fabrication steps is reduced. And the elimination of the surface grinding step facilitates the fabrication.

    摘要: This invention relates to a method wherein the setting angles of cooling water jetting orifices an outer quenching head and an inner quenching head are made 30.degree..+-.10.degree. in the pipe advancing direction with the pipe axis and the number of jetting orifices of the inner quenching head are greater for purposes of higher density for the front one-third of the length of the head and lower for purposes of lower density for the rear two-thirds of the length of the head.Further, the first contact point of inner quenching water within the inner surface of the pipe is so set as to be delayed by 20 to 150mm. from the first contact point of quenching water with the outer surface of the pipe, the outer quenching being carried out when the steel pipe heating temperature is above the A.sub.3 transformation point and the inner quenching is carried out when the temperature of the inner surface of the pipe is just below the A.sub.1 transformation point.As both heads have a fixed angle, water or steam will not enter the unquenched part and the quenching velocity and the hardness of the cross-section of the steel pipe will be improved.

    摘要: To construct an underground structure having smooth wall surfaces in a simple, safe and reliable way, plates (11,12) are buried in parallel, and soil and sand (G1) between the plates is removed. If the places where the plates are to be buried are loosened in advance, they can be buried more easily. A strut member (14) is interposed between the plates, which are used as both forms and sheathing. A hollow body, together with steel plates arranged on both sides of the hollow body, is buried into the ground, the bottom of the hollow body is closed with a shutter, the hollow body is drawn up together with soil in it, leaving the steel plates in the ground, and the remaining steel plates are used as both forms and sheathing. Reinforcement bars are disposed in the groove space thereby formed, and concrete is poured to build an underground structure.
