  • Patent number: 7843049
    Abstract: There are constituted by a tab (1b) on which a semiconductor chip (2) is mounted, a sealing portion (3) formed by resin-sealing the semiconductor chip (2), a plurality of leads (1a) each having a mounted surface (1d) exposed to a peripheral portion of a rear surface (3a) of the sealing portion (3) and a sealing-portion forming surface (1g) disposed on an opposite side thereto, and a wire (4) for connecting a pad (2a) of the semiconductor chip (2) and a lead (1a), wherein the length (M) between inner ends (1h) of the sealing-portion forming surfaces (1g) of the leads (1a) disposed so as to oppose to each other is formed to be larger than the length (L) between inner ends (1h) of the mounted surfaces (1d). Thereby, a chip mounting region surrounded by the inner end (1h) of the sealing-portion forming surface (1g) of each lead (1a) can be expanded and the size of the mountable chip is increased.

  • Publication number: 20050221879
    Abstract: According to the exceptional processing of new damage, when the character (230) succeeds in passing the first devastating flame (340A) and drops into the next devastating flame 340D, since the damage of the devastating flame (340D) is the first damage, the “game continuity ability value” is exempted from decrement. However, if the character (230) drops again into the devastating flame 340G, since it is not the new damage, the “game continuity ability value” is decreased by a predetermined decrement value. According to the exceptional processing of recurrent damage, when the character (230) succeeds in passing the devastating flame (340A), drops into the devastating flame (340D) and drops again into the devastating flame (340G), since the first failure occurs at the devastating flame (340D), the “game continuity ability value” is decreased by a predetermined value. And the “game continuity ability value” is exempted from decrement at the devastating flame (340G) because the drop is a recurrent failure.

  • Patent number: 6786826
    Abstract: A gaming system includes a parent game apparatus and at least one child game apparatus which is connectable to the parent game apparatus. A main game program executes on the parent game apparatus and is ordinarily controlled by player actions on the parent game apparatus. When the main game reaches a predetermined state, the parent gain apparatus downloads a subgame to a child game apparatus connected to the parent game apparatus. The subgame executes on the child game apparatus and transfers a result of the subgame to the parent game apparatus. The result of the subgame affects the state of the main game.

  • Patent number: 6726762
    Abstract: A finely divided pigment is formed of an aggregate of primary particles. A number of primary particles of not greater than 0.1 &mgr;m in particle size is at least 95% of an entire number of the primary particles, and a number of primary particles of greater than 0.1 &mgr;m in particle size is at most 5% of the entire number of the primary particles. The finely divided pigment can be produced by grinding a parent pigment (pre-division pigment) together with a water-soluble inorganic salt and a water-soluble organic solvent in a grinding machine at a temperature of from 30 to 90° C. for 2 to 6 hours under a load, and then removing the water-soluble inorganic salt and the water-soluble organic solvent. A coloring composition comprises a dispersing medium and the finely divided pigment dispersed in the dispersing medium.
