摘要： As a substitute for brazing conventionally employed for attaching curved pad holders to rims of an eyeglass-frame, casting is used for formation of an eyeglass-frame including, in one body with its rims, straight pad holders which should thereafter be bend to a required configuration. Conventional troubles arising from use of brazing are fully removed.

摘要： A number of extremely thin magnetic plates advantageously used for head cores are formed at one time by subsequent application of pressing, sintering, peripheral cutting and separating to a green multilayer construction which includes alternately superimposed metallic powder and parting agent layers, the former resulting in the magnetic plates. High yield is obtained with trouble-free process while making the best use of hard-to-work materials such as Fe-Al-Si type alloys which in general have excellent magnetic properties.

摘要： An improved billet and process for producing a tubular body by forced plastic deformation is disclosed. The billet includes a metallic tubular sheath, a metallic center core and a salt intermediate core. The radial thickness of the metallic tubular sheath is equal to or less than 0.11 times the outer diameter of the metallic tubular sheath. The metallic center core is positioned within the tubular sheath and is surrounded by the salt intermediate core which fills the cylindrical space between the tubular sheath and the center core. In the process of the present invention, the foregoing billet is subjected to forced compulsory deformation to reduce the diameter of the billet. Thereafter, the intermediate core is removed through solution and the center core is drawn out of the sheath in order to obtain the tubular body.
