The pump unit includes a plurality of communication holes and suction holes. The outer housing covers the valve unit and the pump unit with a gap between the outer housing and each of the valve unit and the pump unit. Thus, the outer housing forms vent passages between the outer housing and the valve unit and between the outer housing and the pump unit. The inlet communicates with the vent passage. The outlet communicates with the vent passage. At least one of the inlet and the outlet is displaced from a central axis of the pump chamber. The ejection holes, the film holes, the communication holes, and the suction holes are symmetric about the central axis of the pump chamber.

Abstract: A fin member for a heat exchanger is produced by repeatedly folding a plate over itself into a corrugated shape to form corrugated fins. The folded sections which are formed by the folding are pressed and deformed into a recessed shape to form engagement recesses. A pipe member through which fluid flows is disposed at the engagement recesses. The pressing and deformation of the engagement recesses cause swollen sections to protrude at both sides of each folded section with respect to the folding-over direction of the folded section and form flat butt surfaces at the tips of the swollen sections. Adjacent butt surfaces are caused to be in surface contact with each other with the pipe member disposed at the engagement recesses.

Abstract: In a game, multiple players are communicatively coupled with a network. A progression of game action states is tracked. The action states relate to events that occur during the game and a situation of each of the players that corresponds to the events. Upon reaching a first action state, in which a player is expected to utter a first vociferation based on that player's situation with respect to a game event that occurs in association with the first action state, it is detected whether the vociferation is uttered. The first vociferation is captured. The vociferation may be sent to the other players asynchronously with respect to its capture where it may be rendered locally.
