Abstract: A thermoelectric power generation system includes a shell-and-tube heat exchanger configured such that a tube including double tubes of an inner tube and an outer tube is inserted into a shell, and a thermoelectric power generation module inserted into between the inner tube and the outer tube. The thermoelectric power generation module generates thermoelectric power using a temperature difference between a first medium flowing in the inner tube, such as coolant, and a second medium flowing outside the outer tube in the shell, such as excess water vapor.

Abstract: Provided is a thermoplastic resin composition capable of obtaining uniform electromagnetic absorption performance with no in-plane variation in a molded article thereof as a result of the fluidity being favorable in addition to the reflection loss and transmission loss being high. A thermoplastic resin composition according to the present disclosure which is to be used in an electromagnetic wave absorber and contains a thermoplastic resin (A) and carbon nanotubes (B), wherein the carbon nanotubes (B) satisfy formulas (1) and (2), and a sheet having a thickness of 100 ?m and formed from the thermoplastic resin composition has a sheet surface maximum height Sz of 5 ?m or less when measured according to ISO 25178. (1) The full width at half maximum of the diffraction peak of the (002) plane in powder X-ray diffraction analysis is 2.0-6.0°. (2) The G/D ratio is 0.5-2.0.

Abstract: A thermoelectric power generation system 20 includes a heat exchanger 1 having double tubes which are an inner tube 1a and an outer tube 1b, and a thermoelectric power generation module 2 mounted between the inner tube and the outer tube. The thermoelectric power generation module generates thermoelectric power using a temperature difference between a medium inside the inner tube and a medium outside the outer tube, and a highly thermal conductive elastic sheet 3a, 3b is mounted between the thermoelectric power generation module and the inner tube and/or the outer tube in close contact therewith.

Abstract: A process for making collective packing unit boxes, comprising the steps of feeding a plurality of unit boxes by a first conveyor, thrusting the unit boxes one by one from the first conveyor to a second conveyor perpendicular thereto, thereby to cause the front side of each unit box to contact with the backside of the immediately preceding unit box, respectively, collecting a predetermined number of unit boxes together when the unit boxes are thrust from the first conveyor to the second conveyor, bringing down two flaps extending from the opposite edges of the collected unit boxes inwards, daubing an adhesive on the top flaps of the unit boxes, daubing an adhesive on the upper portions of the two sides of each unit box perpendicular to the contacting sides thereof, pressing a common lid onto the top of the collected predetermined number of unit boxes so that the lid may be adhered on the top flaps of the collected unit boxes, and folding the two opposite side edges of the lid so that the side edges are adhere
