  • Publication number: 20140191922
    Abstract: An antenna apparatus is provided which has a centroid close to a vibration isolation structure and which is hard to vibrate like a pendulum motion when vibration is applied. The antenna apparatus includes a first base plate, an antenna unit disposed at a side of the first base plate and supported by the first base plate, and a counter weight unit disposed at another side of the first base plate opposite to the antenna unit and supported by the first base plate. The antenna apparatus further includes a vibration isolation structure having one end fixed to the first base plate to suppress a vibration of the first base plate, and a second base plate to which other end of the vibration isolation structure is fixed and which is fixed to a moving object or a structural object.

  • Patent number: 8007243
    Abstract: A blower that can reduce noise and enhance efficiency by improving a blade structure of the blower used for, for example, an outdoor equipment of an air conditioner. An impeller includes plural blades attached to a peripheral surface of a boss at intervals in a peripheral direction, and a trailing edge of the blade has a protrusion-shaped part in which its central part in a radial direction is curved to expand to a suction side. With such a structure, a discharge velocity of air can be made uniform along the radial direction of the blade, and it becomes possible to reduce noise and to enhance efficiency.

  • Publication number: 20110192186
    Abstract: The rear side outer peripheral edge of a propeller fan rotated and driven by a motor, of a propeller fan drive unit, is surrounded by a bell mouth. An upper plate, a lower plate, a side plate, and a machine room plate constitute an air duct at the suction side, outside the radial direction of the propeller fan. The cross-section of the bell mouth, at a first position in the vicinity where a blade of the propeller fan is closest, and where the distance between the propeller fan and the plate constituting the air duct outside the radial direction is relatively narrow, is made to be such that an expansion angle ?1 of the bell mouth suction side is made small. The overlapped height Hb of the propeller fan and the bell mouth is made large against a cross-section at a second position where the distance between the propeller fan and a plate is relatively large. The shape of the cross-section of the bell mouth is made to change gradually between the first position and the second position.

  • Publication number: 20110017427
    Abstract: A now-noise blower is provided which reduces the turbulence of incoming air flow itself even if there is un-uniformity resulting from circumferential positions around a rotation shaft of air inlet passage. Such a blower includes a blade 1 having its outer circumferential edge 1c warped in a rotational direction and a bellmouth 5 covering the circumference of the blade at the air outlet side, wherein a surface of the bellmouth facing the blade has a convex-shaped first upstream expanding portion 5c upstream extending from a minimum inner diameter portion Pb3 and a concave-shaped second upstream expanding portion 5d further upstream extending, the second upstream expanding portion being continuous from the first upstream expanding portion.

  • Publication number: 20100269537
    Abstract: An air conditioner includes a propeller fan within a unit body, an L-shaped heat exchanger on a lateral surface and a rear surface of the unit body, a bell mouth installed radially outward of the propeller fan, and a plate to partition compressor space from propeller fan space, and to guide an airstream from the heat exchanger toward the bell mouth. A first bell mouth portion, which includes a sectional position and thereabout where a length of a segment connecting an end of the heat exchanger on a fan rotating direction side and a fan center is maximized, extends toward an upstream side longer than a second bell mouth portion which is located at a sectional position in a line-symmetrical relation to the first bell mouth portion with respect to a vertical line passing the fan center.

  • Publication number: 20080019826
    Abstract: The invention provides a blower which can reduce noise and enhance efficiency by improving a blade structure of the blower used for, for example, an outdoor equipment of an air conditioner There is provided an impeller 1 in which plural blades 3 attached to a peripheral surface of a boss 2 at intervals in a peripheral direction are disposed, and a trailing edge of the blade 3 has a protrusion-shaped part 30 in which its central part in a radial direction is curved to expand to a suction side. By adopting such a structure, a discharge velocity of air can be made uniform along the radial direction of the blade 3 and it becomes possible to reduce noise and to enhance efficiency.

  • Patent number: 4608472
    Abstract: A sterilization method and apparatus comprise a coil connected to a high-frequency current generating source to generate a magnetic field in which a device to be sterilized is disposed so that an eddy current is generated in a conductor forming the device or a conductor disposed in the vicinity of the device due to the electromagnetic induction action, whereby bacteria attached to the device is sterilized by heat produced by the eddy current loss. The sterilization method and apparatus is suitable for a device such as a tubular connector for connecting between the abdominal cavity and a disposable container containing a dialysate in the peritoneal dialysis, specifically the continuous ambulatory peritoneal dialysis and which is repeatedly used while exchanging the container.

  • Patent number: 3945522
    Abstract: Apparatus wherein a conveyer supporting goods to be loaded is moved toward the loading place, and thereafter the conveyer is so driven that the goods on the conveyer are forwardly fed, while at the same time the conveyer is moved backwardly or retracted to thereby transfer the goods successively onto the loading place in the arrayed state as they are on the conveyor.
