Abstract: A tape having a cross sectional profile including first and second thick portions and a thin portion provided between the first and second thick portions is provided. The first and second thick portions and the thin portion are made of a resin composition whose main component is polyethylene. The density of at least a part of the thin portion is higher than a density of the first and second thick portions.

Abstract: A zipper tape is in an elongated shape and includes, in a cross-sectional shape, a pair of base strips and engagement portions projecting from surfaces facing each other of the pair of respective base strips, the engagement portions being engageable with each other. At least the engagement portions are each formed of a first biodegradable resin composition having a yield strain of 3.4% or more during a tensile test.

Abstract: There is provided a multistage centrifugal fluid machine capable of improving efficiency of an operation for assembling an inner casing to a high pressure side head flange. The multistage centrifugal fluid machine 100 includes a rotor 3 provided with a plurality of impellers (41 to 81) in an axial direction, a cylindrical outer casing 2, and an inner bundle 1 that is fitted with the outer casing 2 to form a flow passage for the working fluid. The inner bundle 1 includes a high pressure side head flange 11, a low pressure side head flange 12, and an inner casing 5 disposed between the high pressure side head flange 11 and the low pressure side head flange 12. The high pressure side head flange 11 and the inner casing 5 are fastened with a first bolt 142 via an elastic body 144.

Abstract: An item selecting device includes: a display controlling section for displaying a Venn diagram formed from subsets each of which indicates a selectable item on a display screen, wherein each of areas formed by the Venn diagram corresponds to an item group including at least one of the selectable item; a control section for inputting information of a designated area selected from the areas by an input device; and a selected item judging section for cancelling a designated item which is each of elements of the item group corresponding to the designated area from a selected item list when the designated item is set as an item already selected, and for adding the designated item to the selected item list when the designated item is not set as an item already selected. By this construction, the selected item can be easily changed.

Abstract: By uniformly forming an indefinite number of microscopic acicular crystals on a surface of a silicon substrate so as to be perpendicular to the surface of the substrate by plasma CVD method using a catalyst, it is possible to reliably, homogeneously and massively form an ultramicroscopic acicular silicon crystal having a substantial cone shape tapered so as to have a radius of curvature of not less than 1 nm to no more than 20 nm at its tip end and having a diameter of bottom surface of not less than 10 nm, and a height equivalent to or more than the diameter of bottom surface, at a desired location.
