Disclosed is a nanocarbon material-composite substrate including a substrate, a three-dimensional structural pattern formed on the substrate, and a nanocarbon material formed on a surface of the substrate, wherein the nanocarbon material is disposed at least on side surfaces of the three-dimensional structural pattern.

Nanocarbon material-composite substrate and manufacturing method thereof

Relations between crystallinity and performance of a biodegradable resin, between weight-average molecular weight and strength thereof, and between weight-average molecular weight and performance thereof were clarified. As a result thereof, when a microneedle array was provided with microneedles containing noncrystalline polylactic acid which had a weight-average molecular weight of 40,000 to 100,000, it was possible to obtain a microneedle array which could maintain its functional performance.

Microneedle array

A method of dividing a circuit pattern for creating complementary stencil masks corresponding to complementary patterns, the method comprising a step of dividing a circuit pattern into a plurality of complementary patterns including a first complementary pattern comprising a pattern of a cantilevered beam member having a support portion width Wand a length L, and a second complementary pattern comprising a pattern of a both end-supported beam member having a support portion width Wand a length L. The dividing of the circuit pattern is performed in a manner that a aspect ratio A(L/W) of the pattern of the cantilevered beam member is confined to not more than 100, and that a aspect ratio A(L/W) of the pattern of the both end-supported beam member is confined to not more than 150.

A substrate for a transfer mask, which comprises a first silicon layer formed of monocrystalline silicon, a silicon oxide film formed on the first silicon layer and having a thickness ranging from 0.2 to 0.8 &mgr;m, and a second silicon layer formed on the silicon oxide film. A transfer mask which is manufactured by making use of this substrate is featured in that it is possible to prevent a transfer pattern from being cracked or destroyed due to stress from the silicon oxide film on the occasion of manufacturing the transfer mask, thereby providing a defect-free transfer mask.

Disclosed is a mortar.concrete composition comprising a polymer emulsion, a portland cement material and an aggregate, which is characterized in that the polymer emulsion is one prepared by neutralizing a seed polymer with an acid or a salt or by quaternizing it with a quaternizing agent, the surfaces of the emulsion grains being thereby highly densely cationated, where the seed polymer is formed by adding a monomer as represented by the following formula (I) or a mixture of the monomer (I) and copolymerizable ethylenic unsaturated monomer(s) to a seed latex of a carboxyl-modified synthetic rubber latex or synthetic resin emulsion and polymerizing them: ##STR1## The polymer of the invention may noticeably reinforce the strength of the shaped product even when the amount of the polymer added is small. The polymer dispersion of the invention can be applied to not only the conventional ordinary materials but also concrete construction materials, although the application to the latter has heretofore been considered economically impossible.

In pneumatic radial tires for running on rough ground, which are useful for applying to construction vehicles and provided with a tread reinforcing layer composed of a plurality of belts embedded in a crown portion of the tires, which surrounds a carcass composed of at least one cord layer arranged in radial plane of the tire, said tread reinforcing layer comprises a pair of main intersecting belts having different belt width in which cords are arranged so as to intersect with each other across an equator of the tire, and supplemental two belts arranged in the inside and outside of said pair of main intersecting belts respectively, in which cords have an elongation at breakage of at least 40% larger than that of the cords of the main intersecting belts, and an angle of the cords in the belt having the smaller width in the main intersecting belts with respect to the above described equator is 2.degree.-9.degree. smaller than the angle of the cords in the belt having the larger width and an angle of the cords of the supplemental belt positioning between the main intersecting belts and the carcass ply is 35.degree.-60.degree..

Radial tires for running on rough ground

A giant radial tire for off-road vehicles which is obliged to be used under heavy load and which is provided with a highly durable bead portion construction in which that end of the wire cords of the turn-up portion or reinforcing layer which is located below the maximum width position of the tire and disposed outside the bead core is arranged at the position which is higher than the height h of the rim flange of a bead portion mounting rim but lower than the height which is three times higher than the above height h, and the outer coating rubber of the bead portion has a thickness distribution satisfying the following condition given by

Radial tire for heavy load vehicles

A pneumatic tire having a protect rib at its sidewall portion is disclosed. This protect rib includes an articular part for absorbing a tension strain caused on the outer surface of the protect rib when the tire is deformed under loaded condition.

Pneumatic tire having a sidewall protect rib provided with an articular

A pneumatic tire having a highly durable tread of wide width and having a side cut resistance, a cut through resistance of tread and an improved high-temperature durability of tread is obtained by limiting the width of the main belt based on the tread width and limiting the crown radius of the tread based on the tire diameter.

Pneumatic tire having a durable tread of wide width

Vehicle tire

A radial tire for heavy load vehicles such as light trucks, trucks, busses, super-large type construction vehicles, etc. is disclosed. The radial tire comprises a carcass ply composed of a steel cord ply and wound around a bead core from the inside toward the outside thereof to form a turn-up portion. The upper end of the turn-up portion is upwardly extended to a position located between a point passing over the maximum width point of the carcass ply expanded by applying an internal pressure to the tire and a point where a normal drawn perpendicular from a hump to the carcass ply crosses with the carcass ply. The turn-up portion of the carcass ply is separated from the carcass ply by means of a soft rubber layer composed of rubber having a Shore A hardness which is smaller than a Shore A hardness of a coating rubber of the carcass ply and a 300% modulus of elasticity which is 50% to 85% of a 300% modulus of elasticity of the coating rubber of the carcass ply.
