Abstract: A cast-in insertion member out of which a core inserted during casting of cast portion can easily be pulled, and production method thereof are provided. Inside covering portion is formed to cover the interior of one end of pipe. During the casting, inside covering portion is interposed between the inner surface of the one end of pipe and the outer surface of the tip of the core put into pipe, so that a bite between pipe and the core by contraction of pipe due to molding shrinkage of cast portion can be prevented. Inside covering portion includes tapered surface on the side of recess, which gradually widens from the one end to the other end of pipe. After molding of cast portion, tapered surface making contact with the outer surface of the tip of the core gradually widens in the direction opposite to that of putting the core into pipe.

Abstract: An air-conditioning device for a vehicle includes a heat exchanger, a first air flow path, and a second air flow path. The heat exchanger is disposed in an inside space of an intake duct that is provided outside a vehicle interior and that has an opening. The heat exchanger includes a first heat-exchange flow path and a second heat-exchange flow path, and exchanges heat between air flowing in the first heat-exchange flow path and air flowing in the second heat-exchange flow path. The first air flow path introduces, to the first heat-exchange flow path through an opening of the intake duct, air heated by heat generated in an engine, and discharges the air to the outside of the vehicle from the first heat-exchange flow path. The second air flow path introduces, into the vehicle interior through an outside air inlet of the intake duct, outside air introduced into the second heat-exchange flow path.

Abstract: A vehicle heating device includes: a first heat exchanger which performs first heat exchange between an exhaust gas discharged from an engine and first air introduced from outside or inside of a vehicle interior; and a second heat exchanger which performs second heat exchange between the first air subjected to the first heat exchange with the exhaust gas in the first heat exchanger and second air taken into the second heat exchanger from the outside of the vehicle interior, discharges the first air subjected to the second heat exchange to the outside of the vehicle interior, and supplies the second air subjected to the second heat exchange to the inside of the vehicle interior.

Abstract: A dicaffeoylquinic acid-containing beverage of the present invention includes the following components (A) and (B): (A) 0.02 to 0.18 mass % of dicaffeoylquinic acids; and (B) 0.1 to 1.0 mass % of L-arginine, in which a mass ratio between the component (A) and the component (B), [(B)/(A)], is from 2 to 18.

Abstract: A safety device used for a case with a lid, includes a lock pin device having a responding moving member supported in the case, and a lock pin protruding from the responding moving member; a lock member provided on a lid side, and including a cam groove to receive the lock pin; and a spring member. The cam groove includes at least three first portions extending in an opening/closing direction of the lid, having an opening-directional end portion and a closing-directional end portion, and disposed in parallel at a predetermined interval therebetween; and a plurality of second portions connecting the closing-directional end portion of the first portions and intermediate portions of adjacent first portions. A depth of a bottom portion between the first portion and the second portion is different to transfer the lock pin from a first of the first portions to a last of the first portions non-reversibly.
