Abstract: An atomizer includes a T-shaped chamber with tapered insides and an outlet which is in communication with the chamber. A first path is located in a center area in the chamber so as to introduce molten metal therein and two second paths are introduced into the chamber so as to send inert gas into the chamber. A separator is located in the chamber and located at an outlet end of the first path. A narrow passage is defined between an inside of the outlet and the separator. The impact of the inert gas and the molten metal atomizes the metal.

Abstract: A method for rapid prototyping by using plane light as sources treats the raw material by two stages. The first stage includes a step of spreading raw material onto a defined zone by nozzles and rolling the material to have a flat surface and a step of illuminating the raw materials by plane light and electronic beams to cause a first time of physical or chemical changes. The second stage includes a step of using more powerful plane light source with cooperation with portable Digital Micromirror Device (DMD) or Liquid Crystal Display (LCD) to scan the selected zones of the material to cause a second time of physical or chemical changes, and a step of stacking the 2-D images sodas to obtain a solid work piece.

Abstract: A method and device for aligning and connecting an optical fiber (or device) with another optical device, are disclosed. The method rotates the optical fiber about three axes that intersect at the end surface of the fiber core so that rotation of the fiber does not cause a translation of the end of the fiber. This allows the alignment to be done quickly and accurately. Further, by making one of the axes co-linear with the longitudinal axis of the fiber, variations or defects in the end surface (or a lens mounted thereon) can be accounted for in the alignment procedure. Once aligned the housings of the optical devices are soldered together using a hot air nozzle. The nozzle can then direct cool air toward the housings to rapidly cool the solder, or the temperature of the air can be slowly ramped down to provide for controlled cooling of the solder.

Abstract: A pair of eyeglasses having a frame with interchangeable lenses and a method of interchanging the lenses. The frame has a centrally located nosepiece and two end portions. Each lens has a substantially circular aperture adjacent the nosepiece of the frame and a notch adjacent a respective end portion of the frame. The notch fits over a corresponding tang in the frame end to secure the outer portion of the lens while protruding pins on the frame adjacent the nosepiece engage the circular aperture of each lens. A hinged locking mechanism is snapped over that portion of the lens engaging the pins, preventing disengagement of the lenses from the pins. To replace the lenses, the hinged locking mechanism is opened, allowing the lenses to be disengaged from the pins and pulled from the tangs.

Abstract: An ergonomic pillow comprises a body including an inclined surface on either side, an arcuate central recess, and a slope near either side extended from the inclined surface to the recess so that either slope has the highest elevation on a top surface of the body; a front lengthwise projection member having a front slant extended from a bottom of the body adjacent to the recess; first and second cavities on the bottom of the body adjacent to either side and disposed corresponding to either slope; and an elongate third cavity at an underside of the projection member having the same orientation as the projection member. The pillow appropriately support face, ear, spine and shoulder for relaxing head and spine of a user in face-up or side sleeping.
