Abstract: A prize acquisition game machine includes: a prize display unit comprising a housing that accommodates prizes in a game space within the housing; a prize acquisition device comprising arms and is configured to move around the game space and grab at least one of the prizes with the arms; a controller that controls movement of the prize acquisition device; and a storage that stores movement information on past movement of the prize acquisition device in the game space. The controller is configured to control the movement of the prize acquisition device based on the movement information stored in the storage.

Abstract: [Problems] To produce planar heating elements having high exothermic efficiency and provide energy-saving electric carpets, floor heating, wall surface heating appliances and heaters for thawing on roads and/or roofs or antifogging for mirrors. [Means for Solving] To provide a planar heating element produced by applying, to an insulating substrate or the like, an electrically conductive fine carbon fiber film that is fabricated using an aqueous dispersion of fine carbon fibers in which the fine carbon fibers are evenly dispersed in an aqueous solution.
