Abstract: Provided is a game system capable of easily performing the second and subsequent matching processes of the game which is played in two or more rounds. The game system includes a center server and game machines that can be connected to the center server through a communication line, and executes a game played in rounds. In the game system, the center server performs matching on a predetermined number of game machines from the game machines in response to matching requests and gives the same session ID to the game machines which are matched first. Using the session ID, the matching is performed on each of the game machines to which the same session ID is given or on each of the game machines to which the same session ID is not given.

Abstract: To provide a network game system for sharing, among a plurality of game machines, the positions and postures of objects associated with the game machines, while suppressing an increase in traffic in the communication network.

Abstract: To provide a network game system for enabling the player of a game to immediately find out, when a moving object, such as a bullet object or the like, contacts another object in a virtual space, from where the moving object came, by looking at the game screen image. Each of the game machines comprises a contact determination unit for determining whether or not the moving object contacts another object (402) placed in the virtual space; a contact direction acquisition unit for acquiring a contact direction of the moving object relative to the other object (402) when the contact determination unit determines that the moving object contacts the other object (402); and a contact image displaying unit for displaying an image (84) in accordance with a direction of a contact surface of the other object (402) and the contact direction at a position in the other object (402) in accordance with a contact position of the moving object.

Abstract: A reciprocal-movement power tool includes a movable blade reciprocally movably provided on a main body. A receiving plate that supports an angle iron to be cut is supported on the main body at a position in front of the movable blade. The movable blade is fixed on a front tip of a rod-shaped shuttle screw. The shuttle screw moves back and forth in the axial direction within a tubular screw shaft. The screw shaft is carved with a female screw portion and is rotated through a joint spindle that is deceleratingly rotated upon rotation of the motor through a deceleration means. The shuttle screw has a male screw portion that is threadingly engageable with the female screw portion.

Abstract: A reciprocal-movement power tool is applied to a cutting device. A movable blade 13 is reciprocally movably provided on a main body. A receiving plate 20 that supports an angle iron 30 to be cut is supported on the main body at a position in front of the movable blade 13. The movable blade is fixed on a front tip of a rod-shaped shuttle screw 12. The shuttle screw 12 moves back and forth in the axial direction within a tubular screw shaft 11. The screw shaft 11 is carved with a female screw portion 11d and is rotated through a joint spindle 9 that is deceleratingly rotated upon rotation of the motor 5 through a deceleration means 8. The shuttle screw 12 has a male screw portion 12b that is threadingly engageable with the female screw portion 11d. Rotation of the screw shaft 11 causes axial movement of the shuttle screw 12 because of the threading engagement between the female screw portion 11d and the male screw portion 12b.

Abstract: A DC power source unit includes a main unit that generates DC voltage, and an output cable. The output cable is connected, either integrally or detachably, at one end to the output of the main unit and another end to an adapter plug. The adapter plug is electrically connected to an electrically powered tool, such as an electrical drill. An output voltage switching unit switches the level of voltage supplied by the main unit to the electrically powered tool, to a level that matches the rated voltage of the electrically powered tool that corresponds to the fitting portion of the adapter plug.

Abstract: An automotive lamp which includes a lamp body, a gasket disposed between the lamp body and an automobile body panel for sealing a back side of the lamp, a seal leg projecting from the lamp body for attaching thereto the gasket, wherein the foamed gasket is molded integrally with a tip end part of the seal leg.

Abstract: A DC power source unit includes a main unit that generates DC voltage, and an output cable. The output cable has one end connected to the output of the main unit and another end attached to an adapter plug. The adapter plug Is electrically connected to an electrically powered tool, such as an electrical drill. Current flowing in the tool is detected every predetermined interval and accumulated electrical quantity is computed based on the detected current flowing in the tool. Based on the accumulated electrical quantity, the temperature of the tool is predicted. When it is determined that the tool is heated up to a first critical temperature based on the accumulated electrical quantity, an alarm unit is actuated. When it is determined that the tool is further heated up to a second critical temperature, supply of current to the tool is interrupted.

Abstract: A motor is housed in a main body and a transmission gear of a series of three transmission gears is mounted to a motor shaft. The last of the series of transmission gears is mounted on one end of an elongated and distortable connection rod. A first bevel gear is attached to the other end of the connection rod. A second bevel gear, which in engagement with the first bevel gear, is attached to one end of a spindle. The spindle extends in a direction perpendicular to the direction in which the connection rod extends. A wheel shaped bit is attached to the other end of the spindle. Rotation of the motor is transmitted to the bit via the three transmission gears, the connection rod, the two bevel gears, and the spindle. To cut a workpiece, the rotating bit is repeatedly moved back and forth into the surface of the workpiece. A handle is attached to the main body and extends in a plane which contains an axis of the motor shaft.

Abstract: A saber saw assembly includes a vice for clamping an object to be cut and a saber saw having a saw blade to be operated in reciprocating motion. The saber saw is arranged to cut the object with the reciprocating saw blade while the object is clamped by the vice. The vice is in the form of a pipe wrench. The pipe wrench clamps the object when rotated in a clamping direction while releases the object when rotated in a releasing direction opposite to the clamping direction. Accordingly, by using the pipe wrench for the vice, the clamping and releasing operations for the object are simplified to enhance the working efficiency for cutting the object.
