Abstract: An object of the present invention is to provide a heat storage composition excellent in slow flame retardance and a heat storage member excellent in the slow flame retardance. Another object of the present invention is to provide an electronic device including a heat storage member, and a manufacturing method of a heat storage member. The heat storage composition according to an embodiment of the present invention contains a heat storage material and a flame retardant, in which a specific condition A is satisfied. The heat storage member according to an embodiment of the present invention contains a heat storage material and a flame retardant, in which a specific condition C is satisfied.

Abstract: Probability of prize occurrence is easily controlled without provision of a blank between symbols on a reel. A gaming machine comprises: a lower image display panel configured to variably display a plurality of symbol arrays with a plurality of symbols including normal symbols and specific symbols more advantageous than the normal symbols, and then display a game result by rearranging the symbols in a symbol display region containing a matrix of cells; bet buttons capable of receiving a bet; and a controller configured to run a normal game which rearranges symbols on the symbol display device on condition that a bet is placed, the controller is configured to modify the symbols arrayed in the plurality of symbol arrays, so that the ratios of the specific symbols to the total number of the symbols in all the symbol arrays increases with an increase in the bet amount.

Abstract: A method of manufacturing a reel for a slot machine according to an embodiment of the present invention includes: forming an opening in a reel strip on which a plurality of first symbols are printed; forming a second symbol on an optical sheet by vacuum forming the optical sheet to form a symbol piece, the second symbol including a protrusion and a depression; attaching the symbol piece to the reel strip such that the second symbol is exposed through the opening of the reel strip; and attaching the reel strip to a reel frame for the slot machine.

Abstract: There is provided a gaming machine capable of providing an effect for symbol display during a stop and/or rotation of a reel, by use of a totally non-conventional effect element, which is an angle of a line of sight to an outer circumferential surface of the reel. Reel strips M32 each having symbols 501 are respectively disposed on outer circumferential surfaces of cylindrical reels M31 each configured to be rotated with its cylinder central axis being held at a predetermined position. Each reel strip M32 includes a color shifting layer M321 configured to selectively reflect and transmit predetermined wavelengths of visible light depending on the incident angle.

Abstract: Provided is a reel unit for a gaming machine which suppresses decrease in visibility of a reel belt due to the formation of image of light source on a reel even if light emission intensity for illuminating the reel is high. It is provided a first light diffusion sheet with translucency having a light refraction surface including a surface formed thereon for refracting light passing therethrough in various directions, the first light diffusion sheet stacked on a base sheet; and a second light diffusion sheet having the light refraction surface, the second light diffusion sheet stacked on the first light diffusion sheet.
