Abstract: A multi air chamber tire 1 includes a tread portion 4, a pair of bead portions 2, a pair of sidewall portions 3, and partition walls 30 respectively provided to half portions of a tire which are defined with respect to a tire equator plane, the partition walls 30 partitioning an inner cavity of the tire to form a plurality of air chambers disposed adjacent to each other. Each of the partition walls 30 includes a first coupling portion 9a and a second coupling portion 9b coupled with a tire inner wall surface. When the tire 1 is filled with fluid, a first air chamber 20 is formed in a space inward of the partition walls 30 in a tire width direction, and a second air chamber 21 is formed in each space between a partition wall 30 and the tire inner wall surface of a sidewall portion 3.

Abstract: An embodiment of the present invention makes it possible provide a reinforcement structure which (i) makes it possible to reinforce an optical fiber in a simple manner and (ii) decreases the likelihood of degradation of a heat-shrinkable tube. A reinforcement structure (1) includes a tension-resistance member (13), a heat-shrinkable tube (16) which bundles a plurality of optical fibers (11, 12) and the tension-resistance member (13), and a radiator (15) which is in thermal contact with the tension-resistance member (13). The tension-resistance member (13) has a flat surface which faces respective circumferential surfaces of the plurality of optical fibers (11, 12).

Abstract: A multi air chamber tire 1 includes a partition wall 30 configured to define and form a plurality of air chambers 20 disposed adjacent to each other in an inner cavity of a tire, and a ventilation member 10 provided to the partition wall 30, and configured to connect the plurality of air chambers 20 in a state where ventilation is allowed. The ventilation member 10 allows ventilation between the plurality of air chambers 20 when a predetermined condition is satisfied indicating that fluid is being injected into at least one of the plurality of air chambers 20 from outside of the tire, and the ventilation member 10 shuts off the ventilation between the plurality of air chambers 20 when the predetermined condition is not satisfied.

Abstract: A portable turning machine includes a support placed on and fixed to a floor, a ring base supported by the support, a turning ring that is turnably supported by the ring base and arranged on an outer circumference side of a collector ring, a motor for turning ring that turns the turning ring, and a tool that is attached to the turning ring and is used for performing corrective machining of the collector ring. The ring base has a structure that is dividable into a lower dividable type ring base and an upper dividable type ring base. The turning ring has a structure that is dividable into a lower dividable type turning ring and an upper dividable type turning ring.

Abstract: The present invention provides a pneumatic tire having a bead core embedded in a bead portion of the tire, the bead core being constituted of a strand as a rubber-coated single bead wire wound around the bead portion to be juxtaposed in plural columns in the axial direction and stacked in plural rows in the radial direction to form a torus structure, characterized in that: the bead core as the torus structure is constituted of two columns of the bead wire juxtaposed in the axial direction; a winding-start end and a winding-terminal end of the bead wire are situated at the outermost rows in the radial direction of the corresponding columns thereof, respectively; and at least one of an interval between the winding-start end and an inner peripheral layer adjacent to the winding-start end of the bead wire and an interval between the winding-terminal end and an inner peripheral layer adjacent to the winding-terminal end of the bead wire is larger than any other intervals between two adjacent bead wires of the bead

Abstract: Provided is a polyoxymethylene resin composition which has excellent molding characteristics (releasing property and molding cycle) and suppresses the generation of formaldehyde. Specifically the polyoxymethylene resin composition is prepared by blending (A) 100 parts by weight of a polyacetal copolymer containing 1 mmol/kg or less of hemiformal terminal, mmol/kg or less of formyl terminal, and 0.5% by weight or less of unstable terminal; (B) 0.01 to 20 parts by weight of one or a mixture of two or more of a guanamine compound (b-1) and a hydrazide compound (b-2); and (C) 0.1 to 5 parts by weight of an ester compound having 50% or more of esterification percentage.

Abstract: The present invention is to provide a test device for a multi-items where in all the test papers for all items for one test are wetted by one shot dropping and transportation of a detecting part (module) or a test device is not required upon measurement. Also, the present invention has the object to provide an analyzer for a test device which makes it possible as in the known visual tests to conduct measurement easily while the test device is kept on a cup and thus can be used in bed side medical examinations and regional medical examinations with no considerable problem.
