摘要:
At an interior portion of a suction nozzle body, an impeller and a brush member are installed. The impeller is rotated in response to an air flow produced by a suction force and a brush or a blade member is mounted in a spiral shape along the whole impeller or a part of the impeller and contacts a surface to be subjected to cleaning. The rotary brush rotates integrally with the impeller on the same shaft and no partition wall is provided between the impeller and the rotary brush. A suction nozzle body having a small size, and which is of light weight and provides for silent operation, and a vacuum cleaner using the same, can be provided.

A vacuum cleaner having a vacuum cleaner main body, an electric blower motor provided in the vacuum cleaner main body, a dust collection part provided in the vacuum cleaner main body, a suction nozzle body for communicating with the dust collection part, an impeller having a rotary axis provided in an interior portion of the suction nozzle body and driven by a suction force which is generated by said electric blower motor. At least one of a rotation brush member and a rotation blade member is included in the suction nozzle body and an opening portion of the suction nozzle body is opposed to a surface to be subjected to cleaning, a suction inlet port for the suction nozzle body is provided for sucking air from an outside portion and is located separately from the opening portion of the suction nozzle body. The suction inlet port is provided so as to direct air which is sucked from the outside portion in a direction transverse to the rotary axis of the impeller and an air flow passage is formed in the suction nozzle body so that a part of the air which is sucked from the suction inlet port initially impinges on the impeller to rotate the impeller and then is passed to a region of the surface to be subjected to cleaning and is sucked into the vacuum cleaner main body.

A double pipe connection structure includes a joint member and a double pipe having an inner pipe and an outer pipe coaxially disposed therein. Further, the double pipe connection structure includes a supporting rib formed integrally therewith in an axial direction, wherein the supporting rib connects the inner pipe to the outer pipe. Further, the joint member includes a first hole into which the outer pipe is inserted and a second hole into which the inner pipe is inserted, wherein the second hole has a diameter that is smaller than a diameter of the first hole, and wherein the first and second holes are bored to be aligned in an axial direction. Moreover, in the joint member, a first-pressure connecting hole communicates with the first hold and a second-pressure connecting hole communicates with the second hole, such that a pressure in the first-pressure connecting hole is lower than a pressure in the second-pressure connecting hole.

The invention is principally to provide an archival optical recording medium of high quality which has satisfactory recording/reading characteristics when used in high-speed recording and high-density recording. The invention accomplishes the object with an optical recording medium comprising a resin substrate, a recording layer comprising an organic dye, and a reflective layer, wherein the reflective layer has a first reflective layer and a second reflective layer in this order from the side close to the recording layer, the second reflective layer has a thermal conductivity lower than the thermal conductivity of the first reflective layer, and the first reflective layer has a film thickness larger than the thickness of the second reflective layer.
