Abstract: A machine tool includes a base, a table, a main spindle, and a trunnion unit. The table is installed on the base. A tool is mounted to the main spindle. The main spindle is caused to approach a workpiece on the table along an up-down direction. The trunnion unit is configured to rotatably hold the table on which the workpiece is placed using a rotation axis along a front-rear direction as a center. The trunnion unit is disposed movable in a right-left direction.

Abstract: A heat-shrinkable opaque white film of this invention includes a core layer, and white back and front layers, the core layer having a chromatic color impervious to light at wavelengths of 380 to 500 nm or an achromatic color. The core layer may contain a black, yellow, red, or brown pigment. The heat-shrinkable opaque white film in a preferred embodiment has a transmission factor to light at wavelengths of 380 to 500 nm of 5% or less. In another preferred embodiment of the heat-shrinkable opaque white film, the core layer has an achromatic color and the film has a transmission factor to light at wavelengths of 200 to 600 nm of 3% or less. A shrink label of this invention has the heat-shrinkable opaque white film, and a preprinted ink label layer arranged on a surface of the front layer of the film. A labeled container of this invention includes a container body and the shrink label arranged on the container body.

Abstract: In an engine including a variable timing/lift mechanism for an intake valve, journal portions of a valve-operating cam shaft are supported on cam bearing portions integrally provided in a cylinder head, and an intake rocker shaft is fixed by bolts to rocker shaft fixing portions provided on an upper surface of the cam bearing portions. By bringing opposite sides of intake rocker arms swingably supported on the intake rocker shaft into slidable abutment against positioning faces integrally formed on opposite sides of the cam bearing portions, the intake rocker arms are positioned in a thrust direction. Thus, it is possible to accurately and easily position the intake rocker arms in the thrust direction without the need for a special member.

Abstract: A water passage is provided separately from an intake manifold to interconnect water jackets provided in a front bank and a rear bank of a horizontal V-type engine. An EGR valve is supported on a valve mounting seat which is provided at a front portion of the water passage. A water passageway through which cooling water flows, and a gas passageway through which an EGR gas flows, are defined in the water passage in close proximity to one another. The EGR valve is cooled by cooling wind passed through a fan opening in a radiator and by cooling water flowing through the water passageway. Thus, it is possible to avoid thermal influence on the intake manifold by the EGR valve, and to cool the EGR valve without the need for special cooling means.

Abstract: A heat-resistant alloy having a high creep rupture strength under high-temperature low-stress conditions and excellent resistance to carburization even when used at a high temperature exceeding 1100.degree. C. The alloy comprises, in % by weight, more than 0.1% to less than 1.5% of C, more than 2% to less than 3% of Si, more than 0% to less than 2% of Mn, more than 20% to less than 30% of Cr, more than 25% to less than 40% of Ni, more than 0.6% to less than 2% of Al, and the balance Fe and inevitable impurities. When required, the alloy contains at least one component selected from the group consisting of 0.01 to 0.5% of Zr, up to 0.2% of N, 0.2 to 2.0% of Nb, 0.2 to 2.0% of W and 0.01 to 03% of Ti.

Abstract: A reactor tube for thermally cracking or reforming hydrocarbons comprising a tube member made of Fe-Cr-Ni heat resisting material and a covering layer of self-fluxing alloy fusing to the inner surface of the tube member, the covering layer made of heat resisting material free from Ni or with a low Ni content. The tube member is manufactured by centrifugal casting, and the covering layer is formed by applying the self-fluxing alloy powder by scattering with or without thermit agent or spraying the alloy to the inner surface of the tube member.

Abstract: A reactor tube for thermally cracking or reforming of hydrocarbons wherein a reacting layer contacting hydrocarbons is made of heat resisting steel comprising, in terms of % by weight, 0.3 to 1.5% C, up to 3% Si, 6 to 15% Mn, 20 to 30% Cr, up to 3% Nb, up to 0.15% N, the balance being substantially Fe and a covering layer which covers the said reacting layer is made of Fe-Cr-Ni heat resisting steel and is fused to the reacting layer at their boundary.

Abstract: A reactor tube for thermally cracking or reforming hydrocarbons comprising an outer tube member made of Ni-containing heat resisting material and having enhanced mechanical strength with a large wall thickness, and an inner tube member of small wall thickness fitted in the outer tube member and made of heat resisting material free from Ni or with a low Ni content. The inner and outer tube members have been subjected to a diffusion treatment with a thin coating of Ni-P solid solution provided at the junction therebetween and thereby bonded together.
