  • Publication number: 20240407126
    Abstract: A switching board and a soldering method thereof are provided. The switching board includes a circuit board having a board body and a first metal ring, where the board body has a first surface, and the first metal ring is formed on the first surface and surrounds a periphery of the board body. The switching board further includes a first metal element disposed on the first surface and fastened to the first metal ring by soldering. The switching board has a high pressure resistance and a low leakage rate.

  • Publication number: 20240396389
    Abstract: A synchronous reluctance motor includes magnetic barriers in each magnetic barrier group of a rotor core, each having a shape which protrudes toward a radial inner side and is symmetrical about a q-axis. A portion closer to a circumferential side than the q-axis includes a first portion extending perpendicular to the q-axis and a second portion extending farther toward the circumferential side from a circumferential side of the first portion and radially outward, and the first portions of the magnetic barriers in each magnetic barrier group have the same radial dimension. The first portions of the magnetic barriers other than the radial outermost magnetic barrier have the same circumferential dimension, which is the same as or twice a circumferential dimension of the first portion of the radial outermost magnetic barrier.

  • Publication number: 20240395582
    Abstract: A method of controlling a feedback control system of a semiconductor process chemical fluid in a storage tank includes performing a fluid quality measurement of fluid by a spectrum analyzer positioned adjacent to a dispensing port of the storage tank, and determining whether a variation in fluid quality measurement of the fluid is within an acceptable range. The method further includes in response to a variation in fluid quality measurement that is not within the acceptable range of variation in fluid quality measurement, automatically adjusting a configurable parameter of the semiconductor process chemical fluid in the storage tank to set the variation in fluid quality measurement of the fluid within the acceptable range.

  • Publication number: 20240364156
    Abstract: One aspect of a rotor of the present disclosure is a rotor that includes a rotor core extending along the axial direction and a plurality of auxiliary magnets disposed in the rotor core. The rotor core includes a slit group including a plurality of first slits aligned in a radial direction, and a second slit disposed radially inside the slit group when viewed from the axial direction. The first slit extends along the circumferential direction in a shape protruding radially inward when viewed from the axial direction. The second slit includes a magnet housing portion extending along the radial direction, and a pair of outer flux barrier portions. The auxiliary magnet is disposed in the magnet housing portion with the circumferential direction as the magnetization direction.

  • Patent number: 7864449
    Abstract: A negative refraction photonic crystal lens is provided. The negative refraction photonic crystal lens includes a substrate and a plurality of voids periodically distributed in the substrate. The voids are configured extending along a direction longitudinally perpendicular with an incident direction of a light having a specific wavelength. By suitably selecting a refractive index of the substrate, a radius of the voids, and a lattice parameter of the voids, the negative refraction photonic crystal lens presents a negative refraction characteristic with respect to the specific wavelength, in that the light incident from one side of the substrate can be focused at the other side of the substrate, thus configuring an optical lens. The optical lens is adapted for not only achieving an optimal sub-wavelength focusing performance, but also further improving the imaging resolution of the negative refraction photonic crystal lens by employing an anisotropic material for preparing the substrate.
