20080279681 | Centrifugal Blower - An object is to provide a centrifugal blower with reduced noise. The centrifugal blower is provided with: an impeller; a casing that houses the impeller and forms a spiral flow passage that surrounds a radial direction outside of the impeller; and a driving device that rotates the impeller about an axis. The impeller has: a bottom plate; a plurality of blades provided on a same circumference of the bottom plate; and a substantially annular plate shape shroud that has the blades interposed between it and the bottom plate, and that is disposed concentric with the bottom plate, and that connects end sections of the respective blades. The shroud has: an inclined section that comes closer to the bottom plate moving from a radial direction inside to a radial direction outside; and a shroud side barrier that rises from a position on the radial direction outside of the inclined section towards a side opposite to the bottom plate. The casing is provided with a bell-mouth that opens from a radial direction inside of the shroud to a radial direction outside, and a casing side barrier that projects to an area between the inner periphery of the shroud and the shroud side barrier. | 11-13-2008 |

20100226766 | Centrifugal Blower - It is intended to provide a centrifugal blower capable of suppressing the generation of noise including periodic noise that is caused by interference between a tongue and an impeller. The centrifugal blower is provided with an impeller ( | 09-09-2010 |
20100260608 | PROPELLER FAN - Provided is a propeller fan that can prevent deformation of the propeller fan while maintaining the basic performance thereof, such as the air blowing performance, efficiency, and noise performance. In a plastic propeller fan including a hub and a plurality of blades integrally molded in a radial pattern on the outer circumference of the hub, assuming that the radial size of each blade from the base to the outer peripheral edge is 100, a ring member that joins the plurality of blades together is provided at a dimension position of 5 to 45 from the outer peripheral edge. | 10-14-2010 |
20100272573 | RESIN FAN - There is provided a resin fan capable of enhancing the mechanical strength in a weld part in view of the direction of reinforcing fiber. On the outer peripheral surface | 10-28-2010 |
20110114286 | VEHICLE HEAT-EXCHANGE MODULE AND VEHICLE HAVING THE SAME - An object is to provide a vehicle heat-exchange module capable of optimizing the whole of a stator blade that deflects a flow in the swirling direction produced by a cooling fan, thereby reducing the work performed by the cooling fan and eventually reducing the input power to the cooling fan, and to provide a vehicle having the vehicle heat-exchange module. According to the vehicle heat-exchange module ( | 05-19-2011 |
20120228656 | SEMICONDUCTOR LIGHT EMITTING ELEMENT - [PROBLEM] A light extraction efficiency increases by suppressing a reflection of a semiconductor layer and a transparent substrate. | 09-13-2012 |
20130126907 | GROUP III NITRIDE SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME - [Problem] To provide a group III nitride semiconductor device and a method for manufacturing the same in which dislocation density in a semiconductor layer can be precisely reduced. | 05-23-2013 |
20140312004 | ETCHING METHOD - Provided are an etching method capable of increasing an etching selectivity between a subject material and a resist, a sapphire substrate processed using the etching method, and a light-emitting device including the sapphire substrate. An etching method using a plasma etching apparatus includes: a resist film forming step of forming a resist film on a subject material; a pattern forming step of forming a predetermined pattern on the resist film; a resist degenerating step of exposing the resist film on which the pattern is formed to plasma under a predetermined degeneration condition to degenerate the resist film and increase an etching selectivity; and a subject material etching step of exposing the subject material to plasma under an etching condition different from the degeneration condition to etch the subject material using the resist film having an increased etching selectivity as a mask. | 10-23-2014 |
