Abstract: An information processing device is an information processing device serving as a member device that constitutes a network system, including: a detection unit that performs autonomous inquiry to the connected network system and detects another member device that together forms the network system; and a list management unit that, when the another member device is detected by the detection unit, updates a list indicating member devices of the network system that are newly registered in the network system via the another member device.

Abstract: Provided are: an NAS variant characterized by having sweetness independent of pH in the case of combination with a polypeptide NBS variant by causing substitution mutation or deletion mutation in one or several amino acids out of the amino acid residues constituting a polypeptide NAS; an NBS variant characterized by having sweetness independent of pH in the case of combination with a polypeptide NAS variant by causing substitution mutation or deletion mutation in one or several amino acids out of the amino acid residues constituting a polypeptide NBS; a dimer comprising a combination of the NAS variant and the NBS variant; a recombinant vector containing a gene encoding the NAS variant and a gene encoding the NBS variant; and a transformant containing the vector.

Abstract: An object of the present invention is to discover a substance with sweetness independent of pH and to provide a novel composition with sweetness characterized by containing the substance. Provided are: an NAS variant characterized by having sweetness independent of pH in the case of combination with a polypeptide NBS variant by causing substitution mutation or deletion mutation in one or several amino acids out of the amino acid residues constituting a polypeptide NAS; an NBS variant characterized by having sweetness independent of pH in the case of combination with a polypeptide NAS variant by causing substitution mutation or deletion mutation in one or several amino acids out of the amino acid residues constituting a polypeptide NBS; a diner comprising a combination of the NAS variant and the NBS variant; a recombinant vector containing a gene encoding the NAS variant and a gene encoding the NBS variant; and a transformant containing the vector.

Abstract: A refrigerant tank includes a base plate made of cooper and a reinforcing frame made of stainless steel. A block made of copper extends through the reinforcing frame and has one face in contact with the base plate and an opposite face in contact with a heating body. Heat generated by the heating body is transferred through the cooper block and through the copper base plate to refrigerant inside the refrigerant tank. The stainless steel reinforcing frame provides strength to the refrigerant tank to allow the heating body to be pressed against the heating tank.

Abstract: A container composes the refrigerant tank 1 including: a block 13 made of copper, one face of which is exposed inside the refrigerant tank 1, the other face of which is contacted with the heating body 90; and a lamination plate 12 composed of three layer structural material in which a reinforcing material 122 is interposed between skins 121 made of copper, the lamination plate 12 being joined to the block 13. Further, heat can be transferred between the refrigerant and the heating body 90 via a block 13 made of copper, the heat transfer characteristic of which is good. After the completion of the brazing process, the rigidity of the container composing the refrigerant tank can be ensured by a reinforcing member 122, the rigidity of which is higher than that of copper.

Abstract: A boiling cooler includes a refrigerant vessel for reserving refrigerant and a heat radiation unit. A heat-generating member is attached to an outer surface of one of two opposite walls of the refrigerant vessel. The heat radiation unit is mounted at an outer surface of other of the walls. A first wick arranged at an inner surface of the one of the walls extends from a lower portion of the wall to an arrangement position of the heat-generating member when the walls are vertically positioned. Refrigerant boiled and vaporized by the heat-generating member enters the heat radiation unit to be condensed and liquidated, then returning to the refrigerant vessel. The heat-generating member can be effectively cooled regardless of the position of the heat-generating member with respect to the refrigerant vessel, in the cases where the refrigerant vessel is used in the vertical direction and in a horizontal direction.
