PROBLEM TO BE SOLVED: To provide a double window system capable of shielding thermal energy from flowing into an indoor or flowing out to an outdoor through primary reflection of infrared ray using glass processed from normal glass by coating the same with an infrared reflection material and through secondary reflection of the remaining infrared ray not shielded through the primary reflection using low-E glass or glass coated with a thermochromic material.SOLUTION: The present invention is a double window system to shied infrared ray and comprises: a first glass member; a second glass member; and a space member provided in a gap between the first glass member and the second glass member to maintain the gap. A nanomaterial coating membrane for reflecting near infrared ray is formed on one surface of the first glass member and a thermochromic material coating membrane is formed on the one surface of the second glass member.

PROBLEM TO BE SOLVED: To provide a multipurpose anisotropy particle arrangement and manufacturing method thereof, with thinning, weight reduction and shortening achieved, and capable of coupling two electrodes with fine pitches by repetitive crimping. SOLUTION: The anisotropy particle arrangement 100 consists of an elastic polymer layer 120, and an elastic electrical conductor 110 or an elastic heat conductor 110 placed so as an upper part and a lower part to be exposed in the elastic polymer layer 120. The manufacturing method of the anisotropy particle arrangement 100 includes a step for preparing a single layer of the elastic electrical conductor 110 or the elastic heat conductor 110, and a step for forming the elastic polymer layer 120 by filling elastic polymer between single layers of the elastic electrical conductor 110 or the elastic heat conductor 110 so as the upper part and the lower part of the elastic conductor 110 or the elastic heat conductor 110 to be exposed.

Abstract:
PROBLEM TO BE SOLVED: To provide a gripper capable of gripping various fine bodies without the risk of applying a high volt and heat to an object, and to provide a drive method used for the same. SOLUTION: When a piezoelectric driving part 250 is extended/contracted, contact parts 230, 240 are correspondingly moved. When the contact parts are moved, links 131, 132 push and pull arms 111, 112 and nippers 151, 152 through bending structures 210, 220, and accordingly the leading ends of the nippers 151, 152 are opened and closed to grip the fine body.
