    摘要： An audio communication apparatus for an MRI apparatus performs unidirectional or bidirectional audio communication between a subject in a gantry provided in an examination room and an operator in a control room. An acoustic transducer for transmission and/or reception provided on the subject side is formed by a bone conduction microphone and/or speaker. The bone conduction microphone/speaker transmits a sound to or from the subject by contacting the subject directly or via a protection member, without relying on air as a transmission medium. The apparatus carries out audio transmission without being affected by noise, even in a high-noise environment. The apparatus allows the use of earplugs or sound insulation earmuffs.

    摘要： A microporous film of high molecular weight polyolefin useful in the prepration of filter mediums or non-aqueous battery separators and a process for producing the film are disclosed. The microporous film of high molecular weight polyolefin contains leaf vein-like fibrils as a main constituent on each of which fibrils indeterminate-form crystallites of not more than 1 .mu.m in size flocculate and has an intrinsic viscosity, �.eta.!, of 4 dl/g or more and, preferably, has:(a) a void content of 25% or more;(b) a gas permeability of 1900 sec/100 cc or less;(c) a tensile strength of 0.05 GPa or more; and(d) a gas impermeability-acquiring temperature of 140.degree. C. or lower. The microporous film is produced by subjecting a high molecular weight, biaxially oriented polyolefin film of 60% or more in crystallinity to a heat treatment and, if necessary, to a stretch treatment to thereby melt or dissolve the indeterminate-form portion of the film, then crystallizing it onto the fibrils as crystallites.

    摘要： If ultra-high-molecular-weight polyethylene having an intrinsic viscosity (.beta.) of at least 5 dl/g is grafted with a silane compound in the presence of a radical initiator and extrusion-molded and the extrudate is impregnated with a silanol condensation catalyst after or during drawing and is then exposed to water to effect crosslinking, there is obtained a novel molecularly oriented molded article in which increase of the melting temperature, which is not observed in conventional drawmolded or crosslinked molded articles of polyethylene, can be attained, and even if this molecularly oriented molded article is exposed to a temperature of 180.degree. C. for 10 minutes, the molded article is not fused but the shape is retained and even after this heat history, a high strength retention ratio can be maintained. In this draw-molded article, the adhesiveness and creep resistance are prominently improved while high elastic modulus and high tensile strength inherent to a drawmolded article of ultra-high-molecular-weight polyethylene are retained.

    摘要： This invention provides an acoustic material having high elastic modulus and large internal loss by subjecting a high-modulus stretched polyethylene containing paraffin wax to plasma treatment. When the acoustic material of the present invention is used for a diaphragm of a speaker, for example, it is possible to suppress the fluctuation of frequency characteristics resulting from split vibration, decrease harmonic distortion and improve transient characteristics.
