    Abstract: A motor stator has an annular stator core, and a plurality of tooth portions spaced on the inner surface of the annular stator core which has a slot formed on each of two sides of each of the tooth portions. Each of the tooth portions has a coil wound and a portion of the coil is located in the two slots of each of the tooth portions. Each of the coils is formed by a metal wire coiled around a bobbin several times from the inner side to the outer side. The bobbin has an inner guide frame and an outer guide frame, both of them have a structure with a bottom plate and a side plate that are arranged vertically so that the coil can be attached to the bobbin to miniaturize the motor stator.

  • Publication number: 20240079268
    Abstract: The present disclosure, in some embodiments, relates to a method of forming an integrated chip structure. The method may be performed by forming a plurality of interconnect layers within a first interconnect structure disposed over an upper surface of a first semiconductor substrate. An edge trimming process is performed to remove parts of the first interconnect structure and the first semiconductor substrate along a perimeter of the first semiconductor substrate. The edge trimming process results in the first semiconductor substrate having a recessed surface coupled to the upper surface by way of an interior sidewall disposed directly over the first semiconductor substrate. A dielectric capping structure is formed onto a sidewall of the first interconnect structure after performing the edge trimming process.

  • Patent number: 11435506
    Abstract: A solar thermophotovoltaic system has a heat exchanger containing a heat exchange fluid, and a thin-film integrated spectrally-selective plasmonic absorber emitter (ISSAE) in direct contact with an outer surface of the heat exchanger, the ISSAE including an ultra-thin non-shiny metal layer that is strongly absorbing in a solar spectral range and strongly reflective in an infrared spectral range. The metal layer has an inner surface in direct contact with an outer surface of the heat exchanger. A photovoltaic cell support structure with an inner surface in a concentric configuration partially surrounds the ISSAE; and an airgap separates the support structure and the outer surface of the metal layer. Photovoltaic cells are arranged on a portion of the inner surface of the support structure to receive emissions from the ISSAE, and a solar energy collector/concentrator allows solar radiation to impinge a portion of the metal layer.

  • Patent number: 10197711
    Abstract: Thin-film integrated spectrally-selective plasmonic absorber/emitter (ISSAE) that is simultaneously (i) an efficient sunlight absorber; (ii) an efficient heat insulator that enables modest sunlight concentration to produce a high temperature by reducing infrared emission by a hot surface; (iii) a spectrally-selective infrared emitter that supplies infrared photons of the right energy to a targeted photovoltaic cell, thereby matching its bandgap. Additionally, said ISSAE is sufficiently thin to enable its use as a wrapping/cloaking material for use with hot storage pipes containing heat exchange fluid. Said ISSAE is incorporated into a number of solar-conversion apparatus, taking advantage of the unique properties of said ISSAE.

  • Publication number: 20160341859
    Abstract: An optical device for generating narrow-band circularly and elliptically polarized radiation, either by conversion from externally incident light or through thermal emission of heated objects. The optical device includes a metasurface comprised of unit cells, where each unit cell contains structural elements or features that break two mirror inversion symmetries of the unit cell and couple bright and dark resonances. In this manner, the optical device emits circularly polarized radiation that does not exhibit a preference for right-hand circularly polarized light or left-hand circularly polarized light incident upon it. As a result, multiple of such optical devices with different unit cell sizes, geometries and dimensions of the intra-cell elements may be implemented as a tag that thermally emits different states of circularly polarized radiation confined to multiple spectrally-narrow bands.
