  • Patent number: 11839819
    Abstract: A game control method realizes an electronic game that proceeds as a result of objects being arranged in a game field. The method comprises: arranging an object; determining whether or not a group of unit elements arranged adjacent to each other in the game field forms a predetermined shape; managing a region including the group of unit elements that forms the predetermined shape as an erasure-determined region; erasing, from the game field, the group of unit elements included in the erasure-determined region, of groups of unit elements arranged in the game field, if the erasure-determined region satisfies a predetermined condition, and leaving unit elements not included in the erasure-determined region; and performing control such that a new arrangement object can be arranged in squares from which the group of unit elements have been erased.

  • Patent number: 11602920
    Abstract: Adding silica particles having specified collective characteristics to a fluororubber formulation enhances direct adhesion between the fluororubber formulation and a copolymer upon curing. Specifically, as measured before being mixed into the fluororubber formulation, the silica particles have an average value of the product “(particle size)×(circularity)” that is 17.5 nm or higher and 500 ?m or lower. The silica particles may also have an average particle size of between 25.0 nm inclusive and 500 ?m inclusive, and an average circularity of 0.80 or higher. Alternatively, as measured after being incorporated into the fluororubber formulation and then cured, the silica particles have an apparent average value of the product “(particle size)×(circularity)” that is 32.0 nm or higher and 500 ?m or lower. The silica particles may also have an apparent average particle size of between 40.0 nm inclusive and 500 ?m inclusive as measured after being incorporated into the fluororubber formulation and then cured.
