  • Patent number: 11918907
    Abstract: A first game process that proceeds independently of a second game process related to opponents for a user is performed. State data indicating a second game state of the second game process related to each of a plurality of the opponents is sequentially acquired, and a display image including a first image reflecting a first game state of the first game process and a plurality of second images reflecting the second game states indicated by the state data is sequentially generated. The display image is sequentially generated such that the first image is arranged in a first area located at a center of the display image, a second area is located at a position at each of right and left sides of the first area, and the second images are arranged in the respective second areas at the right and left sides. An instruction that changes a game state of the target is made if a game state of the user satisfies a predetermined condition.

  • Patent number: 8336444
    Abstract: A pressure-receiving face plate 29 is mounted on one end face of a piston 12, and a support member 26 is raised on the end face of the piston 12. Disposed on the support member 26 with an allowance are, from the pressure-receiving faceplate 29 respectively, a disk spring 27, a plate 25, and a plunger 28. A flange 26a prevents these members from slipping off the support member 26. When the piston 12 approaches a stroke end, the plunger 28 is inserted in an oil passage 20b and applies a cushioning effect to the piston 12. In addition, a gap between the pressure-receiving faceplate 29 and the plate 25 brought into contact with a cylinder bottom 17 becomes narrow, and produces a squeeze effect such that oil escapes from the narrow gap. This makes it possible to provide a hydraulic cylinder that produces a sufficient impact force at the stroke end of the piston and also reduces noise emitted by the impact force, without increasing a length of the hydraulic cylinder.

  • Patent number: 5988610
    Abstract: A liquid sealed suspension unit includes a first member and a second member which are independent of each other and which are coupled together. A cylindrical rubber mount (43) is fastened to the first member, and the second member is mounted so as to be slidable in an axial direction thereof relative to the cylindrical rubber mount (43). The cylindrical rubber mount (43) has a plurality of rubber layers (46a, 46b, 46c) laminated via a plurality of cylindrical members (45a, 45b, 45c) such that they are different with respect to at least either of (i) thickness in their radial direction and (ii) height in their axial direction. A spring member (57), in the form of at least one spring coil, is interposed between a damper plate member (50) and an inner surface of a vessel (40) at the bottom of the vessel. This construction provides an increased displacement amplitude in the axial direction, and an excellent vibration absorptivity for both a roll and a pitch can be achieved.

  • Patent number: 5845895
    Abstract: This invention relates to a liquid sealed rubber mount capable of displaying an excellent vibration isolating effect in intermediate and high frequency ranges, having a vibration isolating effect with no resonation occurring with respect to even the impact vibration of a wide frequency band, capable of obtaining a large attenuation force for large amplitude vibration, and capable of preventing the occurrence of lateral vibration. Accordingly, a case (11, 51) and a guide shaft (14) are joined to each other by a cylindrical rubber mounting element (17, 58), and a high attenuation liquid (21, 59) is sealed in a liquid sealing chamber housing (20, 53) fixed to a lower end of the case (11, 51), a damper plate (23, 28, 55) being held on a lower end of the guide shaft (14). An elastic member (24, 26, 34, 35, 36a, 36b, 39, 56), which is deformed finely by the distance a due to the resistance of the high attenuation liquid (21, 59) when vertical vibration occurs, is fixed the damper plate (23, 28, 55).
