  • Patent number: 8979513
    Abstract: A lead wire engaging structure includes a first engaging portion and a second engaging portion. One end of the first engaging portion and one end of the second engaging portion are integrally provided at a first mounting portion integrally provided at a second casing wall portion. The first engaging portion forms a first gap between the first engaging portion and the second casing wall portion, and engages four lead wires in cooperation with the second casing wall portion. The first gap allows the four lead wires to pass therethrough. The second engaging portion forms a second gap between the second engaging portion and the first engaging portion. The second gap allows the four lead wires to pass therethrough. The other end portion of the first engaging portion and the other end portion of the second engaging portion are coupled to each other by a coupling portion.

  • Patent number: 8961121
    Abstract: A casing of a centrifugal fan includes a suction port forming wall portion, an opposed wall portion opposed to the suction port forming wall portion, and a sidewall portion connecting the suction port forming wall portion and the opposed wall portion. A tongue portion is provided at the sidewall portion. The tongue portion projects into an air passage in the vicinity of a discharge port to form a narrowed air passage portion within the air passage. A leading end surface of the tongue portion is shaped such that the width of the leading end surface increases from the suction port forming wall portion, where the suction port is formed, to the opposed wall portion. The tongue portion is shaped such that the projecting length of the tongue portion into the air passage continuously decreases from the suction port forming wall portion to the opposed wall portion.

  • Patent number: 8764418
    Abstract: An impeller comprises an impeller body, a plurality of stems, a blade mounting member, and a plurality of blades. The stems radially extend with one end of each stem fixed to a portion of a circumferential wall of the impeller body in the vicinity of a suction port, and are arranged at intervals in a circumferential direction of the circumferential wall. The stems assist the impeller to suck air Jn an axial direction through a suction port during rotation of the impeller. The blade mounting member is disposed concentrically with the circumferential wall of the impeller body. The other end of each stem is fixed to the blade mounting member. The blades are arranged at intervals in the circumferential direction and extend along an axial line toward a second wall portion, with one end of each blade fixed to the blade mounting member.

  • Patent number: 8753076
    Abstract: A centrifugal fan is provided, in which the value of static pressure with respect to the flow rate, namely, the flow rate-static pressure characteristic may be set to a relatively arbitrary value without increasing noise. An impeller of the centrifugal fan comprises an impeller body, a plurality of stems, a blade mounting member, a plurality of main blades, and a plurality of sub blades. The main blades are shaped to suck air into a casing through a suction port when the impeller rotates in a direction of normal rotation. The sub blades are shaped to suck air into the casing through the suction port when the impeller rotates in a direction of reverse rotation opposite to the direction of normal direction.

  • Patent number: 8562297
    Abstract: A curved portion is formed at a corner portion between a shroud and a positive pressure surface of each of a plurality of blades. The curved portion has a curvature that decreases from a suction port or the vicinity of the suction port toward a corresponding one of discharge ports. The curved portion includes a curved surface that is concave in a direction of rotation of the fan and forms a part of the positive pressure surface. The curved portion raised inwardly into an airflow path so that a shortest distance between the outer peripheral portion of a hub and a portion of the curved surface in the vicinity of the shroud may gradually decrease toward the corresponding one of the discharge ports.

  • Patent number: 8197198
    Abstract: A fan system with enhanced air flow-static pressure characteristics and reduced fan noise compared to the related art is provided. The number of duct blades of a duct is the same as the number of stationary blades of an axial flow fan located in front of the duct, and the duct blades correspond to the stationary blades respectively. An end surface of a rear end portion of each stationary blade and an end surface of a front portion of a duct blade corresponding to the stationary blade have the same shape, and they align together and contact each other to form one composite stationary blade, with a discharge port of each axial flow fan communicating with an inlet port of a duct housing located behind the axial flow fan.

  • Patent number: 6602797
    Abstract: A wafer processing system occupies minimal floor space by using vertically mounted modules such as reactors, load locks, and cooling stations. Further saving in floor space is achieved by using a loading station which employs rotational motion to move a wafer carrier into a load lock. The wafer processing system includes a robot having extension, rotational, and vertical motion for accessing vertically mounted modules. The robot is internally cooled and has a heat resistant end-effector, making the robot compatible with high temperature semiconductor processing.
