摘要:
A method of fabricating composite metal wires such as aluminium clad steel wires is disclosd which comprises providing a core of hard metal with a cladding of soft metal by extrusion. In fabricating a composite metal wire by extrusion, a core is generally aligned, polished, cleaned or otherwise pretreated before entering an extruder so that a high and variable tension is imparted to the core. By avoiding such tension variation and maintaining the core under a constant low tension and by electrically heating the core before the core enters the extruder, a composite metal wire of improved quality is fabricated in a stable manner.

摘要:
An object of the present invention is to provide a mass spectrometer, a method of mass spectrometry, and a program for mass spectrometry for narrowing the range in which the mass-to-charge ratio is scanned without the ion peak of the fragment ion becoming out of the range. In order to achieve the above object, a mass spectrometer including a control unit, a display unit provided with an user interface, an ionization chamber, a dissociation chamber, a mass separator, and a detector is provided.

A bearing lubricating device includes: an oiling mechanism for supplying a predetermined amount of lubricating oil to a shoulder peripheral surface of a race ring of a rolling bearing located on a side of a raceway surface of the race ring of the rolling bearing; and air jetting mechanism for jetting air so as to transfer the lubricating oil on the shoulder peripheral surface toward an interior of the bearing, wherein the air jetting mechanism has a receiving space formed in a side member disposed on a side of and adjacent to a nonrotating race ring of the bearing so as to receive air from an outside as well as an air jetting slit communicating with the receiving space, the air jetting slit having an annular shape concentric with the race ring and substantially continuous in a circumferential direction and being formed to be open in such a manner as to be oriented toward the interior of the bearing.
