A load applied to a first input device is sequentially detected, and a first display image to be displayed on a portable display device is sequentially generated based on load data. The portable display device obtains image data representing the first display image, and sequentially displays the first display image represented by the obtained image data. In this exemplary embodiment, when a user performs an operation based on his/her action and thereby a process based on the user's action is performed, the user is allowed to view the result of the process in a favorable situation.

A mechanical valve has a main body having a cylinder hole formed therein, a movable element that is inserted into the cylinder hole and that moves forwardly and rearwardly, and a drive section that drives the movable element. A plurality of openings through which air passes are formed in an internal peripheral surface of the cylinder hole, and the openings are opened and closed as a result of forward and rearward movements of the movable element. A movable magnet is fastened to each of both ends of the movable element. Electromagnets opposing the respective movable magnets are provided in a drive section. The movable element is actuated by utilization of magnetic force of the electromagnets.

A hermetic rotary compressor operates two cylinders simultaneously in the regular operation; however it halts operating one of the cylinders when it selects an operation with a half capacity. A vane room of the halted cylinder is air-tightly sealed with respect to lubricant atmosphere in a hermetic case. An oil-supplying groove is provided to a vane groove of the halted cylinder, and lubricant is supplied to the oil-supplying groove in order to lubricate the vane.
摘要:
Reference coordinates in a coordinate system and designated coordinates in the coordinate system based on coordinate information outputted by a pointing device are set. A distance and direction between the reference coordinates and the designated coordinates are calculated. When the distance has a value smaller than a predetermined threshold value, the distance is converted into a game parameter using a first conversion function is determined. On the other hand, when the distance has a value greater than the predetermined threshold value, the distance is converted into a game parameter using a second conversion function for converting the distance into a value greater than a value into which the distance is converted using the first conversion function. The game is processed using the direction and the game parameter.
