摘要： A machine tool rotational indexing device is provided that is capable of avoiding or restraining the reduction in the preload force of any of rolling element rows or restraining the reduction in the support rigidity of the rotary-side coupling even if the preload is decreased. Rolling elements are arranged in a plurality of rolling element rows between a rotary-side coupling and a stationary-side coupling and a prescribed preload force acts when a joint coupling is located in an unclamped position. The rolling element rows are constructed of a first rolling element row arranged in a direction in which the preload force increases as the joint coupling moves to a clamped position and a second rolling element row arranged in a direction in which the preload force decreases. The first rolling element row is positioned farther apart from the meshing engagement portion of the couplings than the second rolling element row.

摘要： A permanent form for placing a basement concrete wall includes a percolation layer and a water-conduit channel for discharging water leakage or the like from a basement concrete wall. If the basement concrete wall is placed using the form, the percolation layer is impregnated with cement paste of concrete, whereby the form and the basement concrete wall are joined to each other. Redundant water before hardening the concrete, water leakage after hardening or the like flows into the water-conduit channel through the percolation layer, flows downward through the water-conduit channel, and is discharged from the bottom of the form. In addition, heat from the basement concrete wall is cut off by a heat insulating layer provided on the side of the interior as viewed from the water-conduit channel.

摘要： A container composed of a plurality of container materials the opposing parts of which are sealed by heat sealing, wherein at least an opening start part of the sealed portion is of a laminated structure consisting of the plurality of container materials and an intermediate material inserted therebetween. The intermediate material and one of the container materials are tightly sealed, and the intermediate material and another of the container materials are sealed easily peelably. The inside end edge of the easily peelable seal portion is positioned more toward the center of the container than the inside end edge of the tight seal portion. At an opening start position, the outside end edge of the easily peelable seal portion is positioned more toward the center of the container than the outside end edge of the tight seal portion, and the intermediate material is provided so as to jut outwwardly of a heat sealing flat portion of a container flange. The strength of peeling of this sealed container from its central side is high enough to withstand retorting or the like, and opening of the container from outside can be effected by hand accurately and stably.

摘要： An internal combustion engine intake duct device is provided with an intake duct body and an air flow directing structure. The intake duct body has an inlet, a left outlet and a right outlet with an intake air passage formed in the intake duct body for supplying intake air from the inlet to left and right outlets. The inlet is disposed on an opposite side of the intake duct body from the left and right outlets and laterally between the left and right outlets in a top plan view. The air flow directing structure is arranged in the intake duct body to direct a flow of intake air entering from the inlet toward the left and right outlets. The air flow directing structure includes a first sound reflecting part serving to block sound from the left intake pipe and a second sound reflecting part serving to block sound from the right intake pipe.
