    摘要: The present invention provides a propeller fan having a blade trailing edge of a sawtooth shape, in which the flows on the negative pressure side and the pressure side of a blade join gradually, so that the velocity loss is decreased in the vicinity of the trailing edge. As a result, the velocity gradient decreases and the generation of turbulence is reduced as compared with the conventional propeller fan, so that the noise is reduced and the fan efficiency is enhanced.

    摘要: The stacked heat exchanger of the present invention has a structure wherein grooves are brazed together to seal the external surface of the coolant passage, further grooves are brazed together to form a partition between the straight incoming and outgoing flow passages, and least one groove in the straight incoming and outgoing flow passage section which groove runs in parallel with the grooves earlier mentioned is formed on the formed plates. With this structure, drain water flows down promptly through these grooves and the splashing of the drain water into the downstream area of the heat exchanger can be prevented.

    摘要: Disclosed is a feature that collects dust particles that arise from a processing operation of an impact tool. The dust collection device collects dust that arises from of a processing operation and is attached to the impact tool that performs a pre-determined processing operation on a processed member by way of a tool bit mounted to the tip region of the tool body being linearly operated at least in the lengthwise direction. The dust collection device has a dust collection unit of which the tip opens as a dust intake port and the contour shape is formed unevenly around the long axis of the tool bit. The position of the dust collection unit is freely selected around the long axis of the tool bit, and it is possible to cause the position to change around the long axis of the bit.

    摘要: A dust collection device, that collects dust particles generated by an impact tool, has a feature that enables the attachment of the device to the impact tool, which is not provided with an attachment section for the device. The dust collection device has a tool body and an auxiliary handle, attached removably to the tool body, and is attached to an electric hammer that, in the lengthwise direction, linearly operates a tool bit mounted to the tip region of the tool body, and collects dust generated by the electric hammer. The dust collection device has: a dust collection unit that has a dust intake port at the tip; a dust collection hose, connected to the dust collection unit, for transferring dust to the downstream side; and a hose-holding unit that holds the dust collection hose. The hose-holding unit can be attached to and removed from the auxiliary handle.
