Abstract: Provided are a sea-island type composite multifilament which includes a thermoplastic elastomer resin as an island component, and an ultrafine multifilament prepared from such a sea-island type composite multifilament. The sea-island type composite multifilament includes an island component and a sea component. The island component includes a thermoplastic elastomer resin (A) having at least one of a Shore A hardness of 90 or less, a Shore D hardness of 60 or less, or a Rockwell hardness (R scale) of 70 or less. The sea component includes a water-soluble or easily alkali-soluble thermoplastic resin (B). The sea-island type composite multifilament has an average single island diameter of 8000 nm or less.

Abstract: An instrument manipulation system includes instruments disposed in a predetermined area, and a first manipulation terminal including: a first display unit that displays at least one of disposition positions of the instruments and a range covered by functions of the instruments; a first designation range input unit that receives an input of a designation range for designating at least one target instrument to be manipulated; a first identification information input unit that receives an input of identification information set in the designation range; and a first instrument control unit that causes the target instrument to perform a predetermined operation.

Abstract: A composite fiber contains a component A as a core component and a component B at least partially covering the component A. The component A contains a vibration damping elastomer having a peak top intensity of tan ? of 0.5 or more. The component B contains a thermoplastic elastomer having a peak top intensity of tan ? of less than 0.5. The component B covers 70% or more of the cross-sectional perimeter of the component A in the fiber cross-section.

Abstract: Provided is a polyamide fiber having excellent color developability, as well as a method for producing such a polyamide fiber, and a fiber structure. The polyamide fiber comprises a polyamide resin composition comprising a polyamide resin and an amino group-containing color enhancer, the polyamide fiber having terminal amino groups at a concentration of from 5.0 ?eq/g to 40.0 ?eq/g. Such a fiber can be produced by a production method at least comprising: melt-kneading a polyamide resin composition including a polyamide resin and an amino group-containing color enhancer to give a melt-kneaded product having a predetermined melt viscosity; and spinning the melt-kneaded product to give fibers.

Abstract: Provided is an electroconductive composite fiber having excellent antistatic capability and cationic dyability as well as a fiber structure including the same. The electroconductive composite fiber at least includes an electroconductive layer and a non-electroconductive layer disposed in contact with the electroconductive layer, wherein the electroconductive layer contains an electroconductive substance, and the non-electroconductive layer contains a modified polyester comprising a phosphonium-containing dicarboxylic acid component as a copolymerization component.

Abstract: The purpose of the present invention is to provide a highly efficient method for capturing images inside a confined space without the need for direct visual observation by an inspector. Provided is an unmanned aerial vehicle equipped with at least four rotors, a drive device that drives the rotors, a control signal generation circuit that generates a control signal for causing the drive device to drive the rotors, and an imaging camera, wherein said unmanned aerial vehicle is configured to fly within a confined space by driving the rotors while capturing images inside the confined space by means of the imaging camera.
