Welding diffuser insert

Abstract: A diffuser insert is provided for use with a welding diffuser and contact tip assembly comprising a diffuser with an interior chamber configured to receive a wire conduit that supplies electrode wire and a shielding gas used during a welding operation and a contact tip coupled to the diffuser and configured to receive electrode wire. The diffuser insert comprises a diffuser insert body configured to be disposed within the interior chamber of the diffuser, and further comprises an insert bore extending therethrough configured to receive electrode wire. An outer periphery of the diffuser insert has at least one surface feature configured to manipulate a flow of said shielding gas from within said interior chamber of the diffuser and out of exit passages to thereby direct said flow of shielding gas about a molten welding puddle formed during a welding operation.

Active millimeter wave imaging system and method

Abstract: A system and method for millimeter wave imaging, comprises at least one illumination source (10) of a millimeter wave beam; a diffuser array (12) comprising a plurality of diffuser elements (12) for diffusing the beam from the illumination source (12) across the desired sector; and at least one camera (16) for obtaining an image of one or more illuminated subjects within the desired sector.

Diffuser Plate and Backlight Module using the Same

Abstract: A diffuser plate and a backlight module using the same are provided. The backlight module includes a light source module and the diffuser plate disposed on the light source module. The diffuser plate has a plate body, a plurality of light-scattering areas and a plurality of light-gathering areas. The light-scattering areas and the light-gathering areas are alternately disposed on a light-entrance surface or a light-exit surface of the plate body. The light-scattering area includes a plurality of cambered units while each cambered unit has a convex cambered surface. The light-gathering area includes a plurality of prism lenses. Two side surfaces of the prism lenses intersect at an angle θ.

Sewage treatment apparatus and operation method of sewage treatment apparatus

Abstract: PROBLEM TO BE SOLVED: To provide a sewage treatment apparatus which keeps DO of a membrane separation tank a suitable value, controls generation of a causative agent of membrane fouling, and further maintains denitrification reaction in an anaerobic tank and phosphorous release reaction in an aerobic tank a good state SOLUTION: The sewage treatment apparatus includes an aerobic tank 3 which has an air diffuser 5 and aerobically treats a water to be treated by a microorganism, a membrane separation tank 4 which is arranged in the latter step of the aerobic tank 3 and has a membrane separation apparatus 6 for solid-liquid separating the water to be treated, and a first circulation passage 8 for making the water to be treated in the membrane separation tank 4 circulate to the aerobic tank 3, wherein the sewage treatment apparatus includes a first measuring apparatus 20 for measuring an indicator of the aerobic treatment in the membrane separation tank 4, and a first control apparatus 21 which adjusts a circulation amount of the water to be treated through the first circulation passage 8 based on a measured value by the first measuring apparatus 20 COPYRIGHT: (C)2010,JPO&INPIT
