摘要： The present invention relates to a magnetic head in which a magnetic metal film comprising a Co-containing amorphous alloy and a crystallizable glass of the PbO-B.sub.2 O.sub.3 -ZnO system as a solder glass are used. The magnetic head of the present invention has about 2 times higher recording density than the conventional one as a magnetic head for floppy disks and hard disks because an amorphous alloy is used. Since a crystallizable glass is used as the glass, there can be obtained a magnetic head having a high strength and superior humidity resistance and reliability.

摘要： A yarn false twisting device in which two motors 30, 40 are installed separately for each of the drive shafts 30a, 40a of each false twist application element, and each motor is controlled by a control unit C in accordance with changes in the yarn tension. The installation of separate motors for each drive shaft of each false twist application element has enabled the elimination of complex power transmission mechanisms such as an endless belt or idler, making the yarn false twisting device more compact. Furthermore, each motor is controlled so as to rotate in mutually synchronic fashion according to changes in the yarn tension, improving the overall quality of false twisted yarn.

摘要： A flying-type composite magnetic head comprising a slider made of a non-magnetic ceramic and having side rails extending longitudinally on both lateral sides of the head; a slit extending longitudinally in one of the side rails; and a magnetic core. The magnetic core is constituted by a pair of core pieces bonded to each other with a first glass layer and fixed in the slit of the slider with a second glass layer on both sides of the magnetic core. The core pieces have flat opposing surfaces parallel to each other for defining a magnetic gap with at least one of the opposing surfaces formed with an Fe-Al-Si thin layer. The magnetic core is provided in its track surface with a notch for restricting a track width, the notch having a depth equal to or greater than the depth of the magnetic gap, and the remaining thickness of the first glass layer bonding the magnetic core pieces being equal to or greater than the thickness of the magnetic core.

摘要： A controlled cooling apparatus for a wire rod coiled into loops immediately after hot rolling. The coiled wire rod is transported with the loops laid substantially flat with a space of a given pitch from one another on a cooling bed. Nozzles are provided to project a cooling fluid such as forced air from below the cooling bed at an angle of from 40.degree. to 140.degree. with respect to the plane of the cooling bed to cool the coiled wire during its transportation. The nozzles are open in a transverse direction of the cooling bed with a nozzle opening area ratio of from 0.8 to 1.2, to provide uniform distribution of the cooling fluid in the transverse direction, whereby uniform cooling can be accomplished to minimize the variation in the cooling rates at densely overlapped loop portions and at sparsely overlapped loop portions.
