An object of the present invention is to provide a rubber composition that has tensile strength at break and tensile elongation superior to a rubber composition produced without mixing a cellulose nanofiber and to provide a latex immersion liquid that is a raw material for the rubber composition and is used at a latex immersion step. Namely, the present invention provides a latex immersion liquid that includes (1) a rubber latex, (2) a modified cellulose nanofiber having an average fiber length of 200-400 nm, and (3) a defoaming agent and also provides a rubber composition produced through a latex immersion step using the obtained latex immersion liquid.

Methods for forming large molded objects from polyurea coatings that are exceptionally durable, rigid and strong enough to remain intact under all conditions involving structural integrity, even without structural reinforcements. Such methods comprise providing a mold or substrate surface onto which the molded object will be formed. A first gelcoat layer is formed upon the mold, upon which is formed a second epoxy/polyurea coating, followed by a third polyurea coating mixed with chopped fiberglass, and a final fourth epoxy/polyurea coating. The combined coatings are allowed to cure and then removed from the mold. Such methods are exceptionally effective in the manufacture of pools and spas.

A method for producing a containing system for a liquid dispenser having a dimensionally stable outer container and a collapsible inner container, in the form of a pouch, arranged within the outer container. The method includes starting from the outer container, at least one layer of a pouch material being applied to an inner wall of the outer container. For this purpose, the pouch material is applied in the form of a liquid or powder to the inner wall, where, after solidifying or fusing, it forms a ply of a wall, of the inner container. The ply detaches from the inner wall of the outer container when the inner container collapses.

The present invention introduces the use of a carbon nanotube-based material in the production of phased array patch antennas of various shapes and sizes including slot and spiral patch antennas. The use of this material provides the ability for the antennas to withstand high-intensity shock vibrations and other intense disturbances and continue emitting phased array signals. Furthermore, the use of this material for patch antennas allows for the alteration of the desired frequency and directional degree of interest by simply energizing various elements within the carbon nanotube-based material.

A manufacturing method for a pressure tank includes disposing a preform, in which a fiber layer is formed on an outer surface of a liner that forms an internal space of a pressure tank, within a mold, and rotating the preform in a circumferential direction within the mold with a central axis of the preform as a rotation center while resin is injected toward the preform disposed within the mold from a gate.

A method for making a biocompatible three-dimensional object includes delivering, using a delivery system, a biocompatible fluid substance comprising a plurality of particles towards a support body having a matrix surface to obtain a coating layer of predetermined thickness configured for coating the matrix surface, generating a relative movement with at least three degrees of freedom between the support body and the delivery system, and removing from the support body any surplus particles of the biocompatible fluid substance to make uniform the predetermined thickness of the coating layer. The support body is coated with the biocompatible fluid substance to obtain a three-dimensional object having an object surface corresponding to the matrix surface.
