An exhaust gas purification apparatus for purifying exhaust gas exhausted from a diesel internal combustion engine and containing therein harmful substances including particulates, NOx, HC and CO, at least, comprises a removal part for trapping and removing particulates in the exhaust gas, a purification part for purifying NOx, HC and CO through contact, and a heat transfer part for transferring heat generated in the removal part to the purification part.

This pneumatic tire is equipped with: a pair of annular bead cores embedded and disposed at a bead section; a carcass comprising a main body section extending toroidally between the pair of bead cores, and at least one carcass ply having a fold-back section that, continuously with the main body section, results from folding back around the bead core; and a tread rubber installed at the outer perimeter of the crown region of the carcass. The cross sectional shape in the widthwise direction of the tire of the bead cores is polygonal having at least one corner at the main body side of the carcass ply. At the periphery of the bead cores, at least a two-layered stack of organic fiber reinforcing layers is provided resulting from helically winding at least one rubber-covered organic fiber cord inclined with respect to the center line of the transverse plane of the bead cores; the respective organic fiber cords of organic fiber reinforcing layers that are adjacent in the inner / outer direction are caused to extend in mutually intersecting orientations with respect to the center line of the transverse plane of the bead cores, and of the organic fiber reinforcing layers that are adjacent in the inner / outer direction, in the inner organic fiber reinforcing layer, the rubber-covered organic fiber cord is wound leaving a gap in the peripheral direction of the tire at at least a portion thereof without overlapping in the peripheral direction of the tire, and the outer organic fiber reinforcing layer is providing in a manner so as to cover at least a portion of the gap.

Provided is a radical polymerizable resin which has a low viscosity, has excellent workability, rapidly cures by exposure to heat and / or light, and forms a cured product having excellent pliability and heat resistance. A radical polymerizable resin composition is obtained by cation polymerization of an oxetane ring-containing (meth)acrylic acid ester compound represented by formula (1) (where R1 is a hydrogen atom or a methyl group, R2 is a hydrogen atom or an alkyl group, and A is a C4-20 straight-chain or branched-chain alkylene group) alone or together with another compound having cation polymerizability.

A sliding element comprises a sliding surface member, a base made of a material different from that of the sliding surface member, a joining material layer which is disposed between the sliding surface member and the base and joins the sliding surface member and the base to each other, and a sheet member made of an electromagnetic induction heating material. The sliding surface member and the base are joined to each other by heating and melting the joining material layer by means of electromagnetic induction heating of the sheet member.

The present invention provides a stator coil for a rotating electrical machine comprising a stator core and a coil formed by winding an enamel wire in a slot of the stator core, wherein the stator coil is characterized in that the enamel wire is coated with a cured substance of a first insulation wax containing a polyester resin, and the coil is coated with a cured substance of a second insulation wax containing epoxy acrylate resin. The stator coil for a rotating electrical machine has a high fixing strength of an insulating layer, is capable of preventing thermal deterioration of the enamel wire, and has favorable pressure resistance over a long period of time.

The bismuth-based glass of the present invention is characterized by containing Bi in terms of the following mol % in terms of oxides: 2 o 3 25-45%, B 2 o 3 20-35%, 90-100% (excluding 90%) of Bi 2 o 3 +B 2 o 3 +BaO+ZnO+CuO+MnO+Fe 2 o 3 +TiO 2 +V 2 o 5 +Cr 2 o 3 +Co 3 o 4 +NiO as glass composition, molar ratio (Bi 2 o 3 +B 2 o 3 +BaO+ZnO) / (CuO+MnO+Fe 2 o 3 +TiO 2 +V 2 o 5 +Cr 2 o 3 +Co 3 o 4 +NiO) is 2.0 to 3.5.
