An isoprene-based polymer latex composition includes a chloroprene polymer latex (A) and an isoprene polymer latex (B), in which the chloroprene polymer has a z-average particle size of 180 nm or greater and smaller than 300 nm, and a tetrahydrofuran-insoluble fraction of 80 to 99% by mass; the chloroprene polymer latex (A) is (1) a copolymer latex of chloroprene (A 1) and 2,3-dichloro-1,3-butadiene (A-2-1), or (2) a copolymer latex of the above (A-1) and (A-2 1), and another monomer (A-2-2); and the copolymer is obtained by copolymerization in which the ratio of 2,3-dichloro-1,3-butadiene (A-2-1) is 5.0 to 30.0% by mass relative to the total amount of the monomer components chloroprene (A-1) and 2,3-dichloro-1,3-butadiene (A-2-1) of 100% by mass. The isoprene-based polymer latex composition's quality is maintained, and the properties after cross-linking of a molded product obtained by dipping a dipping former into the composition multiple times do not deteriorate.

The rotary electric machine includes a motor unit, and an inverter unit having a power module, a field module, and a cooler. The cooler includes a heat transfer member having, on the one-side surface, a channel groove recessed toward the other side, a lid member, a sealing agent, and a coolant supply/discharge unit; and the lid member is fixed to the heat transfer member with a screw hole, a through hole, and a screw; and, at a position between the screw hole and the through hole, and the channel groove, a recess is provided on one or both of the one-side surface of the heat transfer member and the other-side surface of the lid member, and the sealing agent is applied on the side closer to the channel groove than the recess while no sealing agent is applied on the side closer to the screw hole than the recess.

There is provided a chloroprene copolymer latex composition capable of obtaining a molded product having excellent mechanical properties and flexibility even when vulcanized and molded under milder conditions than before. A chloroprene copolymer latex composition contains a chloroprene copolymer latex (A), a metal oxide (B), a vulcanization accelerator (C), and an antioxidant (D). The chloroprene copolymer latex (A) is a latex containing particles of a chloroprene copolymer which is a copolymer of chloroprene (A-1), 2,3-dichloro-1,3-butadiene (A-2), and sulfur (A-3). The content of the sulfur (A-3) in the chloroprene copolymer is 0.1 part by mass or more and 1.0 part by mass or less when the total amount of the chloroprene (A-1) and the 2,3-dichloro-1,3-butadiene (A-2) is set to 100 parts by mass.

An online video game controlling server includes an online game information storage database for storing game information on an online video game that includes player information on player characters and area information on a game area of the online video game, and a control section for controlling the progress of the video game on the basis of the game information. A shared area and an unshared area are provided in the game area of the online video game. When one player character moves to the unshared area, the control section creates instance information including area specifying information, character identification information and instance creating necessary object information. In addition, the control section server breaks communication between the one player character and the other belonging player character to update the instance information whenever the progress state of the instance creating necessary object changes due to the action of the one player character.
