Abstract: The present invention causes a computer to function as a virtual space generating unit, a game screen displaying unit and a fluid displaying unit. The fluid displaying unit displays pseudo three-dimensional representation of fluid in a virtual space on a game screen. And the fluid displaying unit includes a two-dimensional data acquiring unit for acquiring two-dimensional data including a two-dimensional map by processing at least part of the surface of a three-dimensional object into a two-dimensional manner and a simulating unit for simulating a flow of the fluid on the two-dimensional map and displaying a simulating result on the surface of the object. The two-dimensional map includes height information of each point on the surface of the object. The simulating unit simulates the flow of the fluid on the two-dimensional map based on the height information.

Abstract: A pickup cartridge of the moving magnet type. The vibration center of its vibrating system is stabilized by being concentrated at a certain point without appreciable fluctuations, regardless of the vibration amplitude of the vibrating system. Also, it has a very high conversion efficiency of its displacement-magnetism converting system for converting the positional changes of this vibrating system to changes in magnetism. This conversion efficiency is almost constant regardless of the vibration amplitude of the vibrating system.A damping member is interposed between an armature magnet and a member for supporting this armature magnet. A cantilever attached to the magnet is pulled, jointly with the armature magnet, by a tension wire connected to the base of this cantilever, toward the supporting member in the axial direction of the cantilever. The base end of the cantilever is positioned substantially at the center of that surface of the armature magnet which faces the supporting member via the damping member.
