  • Patent number: 8511528
    Abstract: A technique for improving the cooling performance of a combustion chamber in a combustion power tool is provided. The combustion power tool includes first and second combustion chambers, a partition that separates the first combustion chamber from the second combustion chamber, openings, formed in the partition and communicate the first combustion chamber with the second combustion chamber, and a drive section that moves toward a front end by combustion pressure. The combustion pressure is generated when a flow of flammable gas, which is produced by combustion of the flammable gas in the first combustion chamber propagates to the second combustion chamber through the openings, and burns flammable gas in the second combustion chamber. The combustion gas flows from the first combustion chamber to the second combustion chamber in a direction around a central axis of the second combustion chamber while flowing along an inner wall of the second combustion chamber.

  • Patent number: 8215528
    Abstract: A drive tool includes an ejector, a press member, a press detection switch, an operation member, an operation detection switch, a control unit, an operation state detector, and a report unit. The control unit makes the ejector carry out ejection of a fastening tool when the press detection switch and the operation detection switch are turned on. The operation state detector detects a case where the drive tool comes into one of a plurality of kinds of preset operation states which include at least one operation state other than a state of a battery. Report patterns different for each of the plurality of kinds of operation states are set in the report unit. When one of the operation states is detected by the operation state detector, the report unit reports the detection using the report pattern set corresponding to the detected operation state.

  • Publication number: 20100101660
    Abstract: A channel switching system includes two microvalves i.e. a first valve (stopper valve) and a second valve (water retaining valve). The first valve is openable and closable, and the second valve is operable to block fluid flow by a surface tension force. Changing the first valve from an open state to a close state enables to switch the system from a condition that the fluid flows through the channel where the first valve is mounted by blocking the flow at the second valve by the surface tension force to a condition that the fluid flows through the channel where the second valve is mounted by releasing the system from the condition that the flow is blocked at the second valve by the surface tension force.
