Abstract: A battery pack apparatus includes: a battery pack composed a plurality of rechargeable batteries arranged in parallel, the rechargeable batteries having heat medium passages formed therebetween; a heat insulation cover, formed from heat insulation material, for covering the substantially entire surface of the battery pack with a supply passage and a discharge passage provided between the heat insulation cover and the battery pack, the supply passage supplying a heat medium to the heat medium passage while the discharge passage discharging the heat medium from the heat medium passage; and a supply device for supplying the heat medium to the supply passage. In this battery pack apparatus, heat exchange occurs on the substantially entire surface of each rechargeable battery by making the heat medium flow in the heat medium passages, thereby performing temperature control efficiently and uniformly.

Abstract: A battery pack apparatus including a battery pack having a plurality of rechargeable batteries arranged in parallel, with a cooling medium passage interposed therebetween, a cooling medium feeding device for feeding a cooling medium through the cooling medium passages, and a control section for controlling the charge and discharge of the battery pack. In this configuration, the battery pack apparatus is divided into a first unit including the battery pack and the cooling medium feeding device and a second unit having the control section accommodated in a case. The battery pack of the first unit is connected with the control section of the second unit by means of a harness or metallic connecting member.

Abstract: Two manual controllers are connected to two slots of an entertainment apparatus via connectors, respectively. One of the manual controllers is manipulated as a manual input device by a user. The other manual controller is placed upside down on a table, for example, and moves by vibrations so as to functions as a movable object (movable device). The user can move the movable device synchronously with the movement of an object displayed on a display monitor by manipulating the manual controller.

Abstract: A battery power supply device of the present invention includes a battery pack in which a plurality of battery modules each includes a plurality of cells which are serially connected together both electrically and mechanically, the plurality of battery modules housed in a holder, and the battery power supply device is structured so that a cooling medium flows around each cell and/or each battery module; the battery back is provided with a plurality of vent holes having different aperture areas which are distributed over at least one of inlet and outlet sides of the battery pack such that a cooling medium having a substantially uniform flow rate flows around each cell and/or each battery module.

Abstract: An entertainment system comprises story developing means for allowing a player to a virtually experience a cocking operation in a kitchen of a restaurant registered with a restaurant information table from opening time to closing time of the restaurant, three-minute cooking processing means for allowing a player to virtually experience a cooking operation in a kitchen of a restaurant registered with the restaurant information table for a predetermined time period (for example, three minutes), and competition processing means for allowing a player to virtually experience a cooking operation in a kitchen of a restaurant registered with the restaurant information table, while playing a match game with a plurality of other players.

Abstract: A power supply unit capable of simplifying the structure of a battery case and improving the cooling efficiency by increasing the cross sectional area of a coolant passage. A power supply unit includes a battery case; a plurality of battery modules disposed in parallel, each battery module is composed of three cells connected in series in a row, and the front end and the rear end of the battery module are held by the front part and the rear part of the battery case; a cooling fan for forcing a cooling air to flow in the passage between the neighboring battery modules; a shielding plate for shielding the cooling air from the battery module, which is placed at the upstream side of the passage and; a rectifying fin for increasing the flow rate of the cooling air, which is placed at the downstream side of the passage.

Abstract: An entertainment system has an entertainment apparatus for executing various programs, a manual controller for entering manual control requests from a user into the entertainment apparatus, a monitor for displaying images outputted from the entertainment apparatus, and a speaker for outputting sounds outputted from the entertainment apparatus. The manual controller has motors for imparting vibrations to the user in response to an external request. The entertainment system also has a vibration/sound setting unit for setting up a length of a bar displayed on the monitor according to a control input from the manual controller, setting up a magnitude of vibrations to be generated by the motors depending on the length of the bar, and setting up a type and/or a pitch of sound to be outputted to the speaker depending on the length of the bar.
