    摘要: Proposed is a fabric mattress having a layered structure as a kind of health-promoting bedding goods, which comprises an upper fabric layer, a lower fabric layer and an intermediate fabric layer sandwiched between the upper and lower fabric layers, at least a part of these fabric layers being formed from fibers such as rayon fibers containing very fine particles of tourmaline in an amount of up to 7% by weight. This unique ingredient in the fibers has an effect to emit active electrons and far-infrared light which exhibit an invigorating effect on the human body cells of the person lying on the mattress to promote blood circulation so that even a patient lastingly lying on the bed never suffers from bedsores by using the mattress which can be constructed to have good air permeation.

    摘要: A closed type polygon scanner has a housing, a rotor which is rotatively supported to a rotating shaft fixed to the housing and which includes a polygon mirror, a motor which generates a magnetic force to the rotor and rotates the rotor, and a cover. The cover includes an outer peripheral portion fixed to an outer peripheral portion of the housing, and covers the rotor together with the housing. An opening is formed at a predetermined portion in the cover facing a mirror surface of the polygon mirror through which a laser beam passes, and a window member is fixed to the opening in closed state. An inner peripheral surface of the cover facing the mirror surface of the polygon mirror is formed cylindrically and almost coaxially to a rotating axis of the rotating shaft, and a width in the rotating axis direction of the opening is set to a predetermined width relative to a width of the polygon mirror so that turbulent air generated around the polygon mirror is reduced.

    摘要: A cobalt-containing ferromagnetic iron oxide powder of which constituent particles each is an aggregate of cobalt-containing ferromagnetic iron oxide micorparticles and has a spherical shape of 5 to 200 .mu.m in diameter has an angle of repose of 35.degree. or smaller and accordingly excellent flowability, as well as to a process for producing the iron oxide powder, are provided. This ferromagnetic iron oxide powder consisting of spherically shaped particles, are easily dispersed in an organic binder to return to the original state of microparticles, and provide improved magnetic characteristics when used as a material for magnetic recording media such as a magnetic tape and the like.
