Apparatus for growing carbon nanotube forests, and generating nanotube structures therefrom, and method

The present invention provides apparatus and methods for growing fullerene nanotube forests, and forming nanotube films, threads and composite structures therefrom. In some embodiments, an interior-flow substrate includes a porous surface and one or more interior passages that provide reactant gas to an interior portion of a densely packed nanotube forest as it is growing. In some embodiments, a continuous-growth furnace is provided that includes an access port for removing nanotube forests without cooling the furnace substantially. In other embodiments, a nanotube film can be pulled from the nanotube forest without removing the forest from the furnace. A nanotube film loom is described. An apparatus for building layers of nanotube films on a continuous web is described.

09771980 · 2017-09-26 · ·

A rolling bearing retainer which is formed by insert molding a resinous material together with a core member within a mold, in which the core member is embedded within a resin part made of the resinous material and a support area exposure part is provided at a plurality of locations of the resin part for exposing a support area of the core member supported within a cavity of the mold. The resin part includes a ring shaped body and a plurality of support column bodies extending axially from the ring shaped body and defining a pocket for retaining a rolling element therebetween, and the core member is provided with a ring shaped body embedded part and a plurality of support column body embedded parts extending from the ring shaped body embedded part.

Imprint apparatus and article manufacturing method

Provided is an imprint apparatus that imprints a pattern formed on a mold onto a substrate. The imprint apparatus includes a substrate holder that holds the substrate and can move in a direction along the surface of the substrate; a gas supply unit for supplying a gas into a space between a pattern part of the mold and the substrate; and a wall part that is disposed so as to enclose the space that is supplied with gas, wherein at a position opposed to the substrate and the mold, the wall part faces the substrate holder or the substrate with a gap therebetween.

In-mold labeled container and molding process thereof

The objects of this invention are to set a predetermined height position for the portion of parison or preform that is the first to come in contact with body molding planes of a split mold and to prevent air from being trapped between in-mold labels and the container which is blow molded from the parison or the preform. In-mold labels are fixed to the entire outer surface of body of main container. An annular thinnest wall portion is formed in the wall of the body so that the thinnest wall portion is the first to come in contact with the body molding planes of a split mold. Under this construction, no bulge of air is formed between the body and the in-mold labels fixed to the entire surface of the body.
