  • Publication number: 20100075759
    Abstract: A data storage unit (130) of a parent machine (100) stores downloaded additional data (131). When the parent machine (100) and a child machine (200) wirelessly connect to each other and the child machine (200) sends child machine information to the parent machine (100), a process control unit (120) of the parent machine (100) searches out any additional data that can be provided from the data storage unit (130) based on the received child machine information. That is, the process control unit (120) searches out additional data that matches a progress status of a game in the child machine (200) from among the additional data (131). The parent machine (100) sends the searched-out additional data to the child machine (200). Hence, the child machine (200), which cannot connect to a server, can obtain additional data from the parent machine (100).

  • Publication number: 20090309872
    Abstract: An object selecting device, etc., is provided making possible easy selection of objects displayed in a predetermined order. A display unit (306) of the object selecting device (301) displays objects whose order is further forward so as to hide objects whose order is further back, if objects overlap. A position specifying input receiving unit (308) receives input of position specifying input for specifying a position in a screen. An output unit (307) outputs, of objects displayed on the screen, as a selection result an object furthest forward if there is an objects displayed to a position specified by the position specifying input, and as a selection result an object furthest forward in the order, if there is no object displayed to a position specified by the position specifying input, but there is an object displayed at a position overlapping a two-dimensional area set so as to include the position.

  • Patent number: 5195478
    Abstract: Disclosed is a piston for an internal combustion engine, which includes a land portion, and a skirt portion including a non-coated portion which is formed in an arbitrary shape on a sliding portion thereof and a coated portion which is formed on a sliding portion thereof other than the sliding portion on which the non-coated portion is formed. When the piston is descending, an oil which has adhered on a cylinder bore is introduced into the non-coated portion and accordingly an oil film is established in the non-coated portion. Since the advantageous effects of the coated portion and the oil film are combined in the piston, the sliding resistance can be reduced remarkably. Hence, the coated portion can be inhibited from wearing out, and its function of the sliding resistance reduction can be maintained for a long period of time. In addition, since the non-coated portion does not work as a sliding surface, there arises a reduced sliding surface area which also results in the reduction of the sliding resistance.

  • Patent number: 5052281
    Abstract: A piston installed into a cylinder of an engine includes annular projections formed in axially spaced relation on a top land facing a cylinder inner wall and having a saw-toothed cross-section in which the external diameter of the projections are such that, when cold, that adjacent the lower end of the top land is greater than that adjacent the upper end thereof. Thereby the effective clearance between the top land face and the cylinder inner wall is reduced. This causes a reduction in the hydrocarbon content of the incompletely consumed combustion gas, and prevents the temperature from rising in the top ring groove and thus prevents the wearing of the groove.

  • Patent number: 4776075
    Abstract: A method for manufacturing a piston of an internal combustion engine, especially for forming a piston gallery portion provided in the piston head for cooling the engine. A gallery member made of a metal pipe having a high thermal conductivity or a salt-core having a shape corresponding to the piston gallery is fixed to a fixing member having a peripheral rim and a plurality of fixing legs extended from the rim. The gallery member or the salt-core fixed to the fixing member is cast in the piston, body, and then, the fixing member is cut off from the piston body. The salt-core is melted away by pouring water. By this method, a piston of light weight and having high cooling efficiency can be manufactured.

  • Patent number: 4665948
    Abstract: An electromagnetic fluid flow control valve mechanism has a hollow slide valve linearly movable on and along a core in response to energization of a coil disposed around the slide valve for selective fluid communication between a inlet port and first and second outlet ports through a chamber in a casing. The ratio of a cross-sectional area of the inlet port to that of each of the first and second outlet ports is selected such that the chamber will develop a relatively small vacuum such as of 20 mmAg at maximum. Preferably, the ratio is 6.5 or greater. This arrangement prevents a fluid, typically air, from flowing from the second outlet port back into the chamber.
