Abstract: A suspension apparatus 100 includes a leaf spring 110 in which a front end and a rear end are rotatably supported by a frame 2 of a car and an intermediate portion thereof in a longitudinal direction is attached to an axle 3; and a stay 160 having an engaging portion 161 for blocking rotation of a portion to a rear of a breaking point of the leaf spring 110 when the leaf spring 110 is broken at a portion to a rear of the intermediate portion thereof.

Abstract: A suspension device for suspension of an axle by an intermediate portion of a single leaf spring has first restriction device which restricts, upon breakage of the leaf spring at a position behind the intermediate portion of the spring, the rear portion of the leaf spring from tilting downwardly relative to a shackle, and a second restriction device for restriction of the shackle from pivotally moving backward beyond a predetermined angle. The first restriction device is constituted by a stopper plate on the shackle for support of the rear portion of the leaf spring from below upon breakage.

Abstract: A thermoplastic resin film (i) which has a degree of dimensional change through heating and cooling (?) in the range of from ?2% to 2% as measured by thermomechanical analysis in the range of from room temperature to 135° C., or which has a degree of thermal shrinkage of 1.8% or lower upon heating at 130° C. for 30 minutes or longer; and a label paper employing the same. The label paper has suitability for heated-roll fixing type electrophotographic printers and is satisfactory in curling after printing.

Abstract: A slide member of the present invention is characterized in that it has: a substrate, which is made of a metal; an intermediate layer, which is formed on at least one of the surfaces of the substrate, and which is composed a first resinous composition including a thermoplastic polyimide resin and a polyaryl ketone resin; and a superficial layer, which is formed on the intermediate layer, and which is composed of a second resinous composition including a polyaryl ketone resin. Since the slide member of the present invention is such that it is possible to form it at low temperature, the deterioration of the substrate is suppressed; moreover, it is a slide member having a superficial layer, which includes a polyaryl ketone resin which is good in terms of the adhesiveness to a substrate.

Abstract: A porous resin film which comprises 30 to 90 wt % of a thermoplastic resin containing a hydrophilic thermoplastic resin component; and 70 to 10 wt % of an inorganic or organic fine powder was disclosed. The porous resin film of the present invention is valuable as an ink-jet recording medium since the film shows excellent ink absorbing and drying properties even when a large amount of ink is discharged thereon, and thus can produce thereon a high-definition image.

Abstract: The invention provides a porous resin film having a good absorption of water content as a solvent for aqueous ink or aqueous paste and a recording medium comprising the porous resin film. The recording medium is characterized by the capability of absorbing an ink without density unevenness even during ink jet recording if the ejected amount of ink is great. The invention lies in a porous resin film comprising: a thermoplastic resin in an amount of 30 to 90% by weight; and an inorganic and/or organic finely divided powder in an amount of 10 to 70% by weight, wherein the inorganic and/or organic finely divided powder is surface-treated with a surface treating agent (A) made of a copolymer of diallylamine salt or alkyl diallylamine salt (a1) with a nonionic hydrophilic vinyl monomer (a2) and an anionic surface treating agent (B), and the porous resin film has a liquid absorption capacity of not smaller than 0.5 ml/m2 as measured by “Japan TAPPI No. 51-87”.
