  • Publication number: 20210016564
    Abstract: An image forming apparatus includes a recording head, a controller, a first detector, and a second detector. The controller calculates a viscosity of ink in each of nozzles based on a temperature, a humidity, and an elapsed time. The controller determines, among the nozzles, a nozzle in which the viscosity is equal to or higher than a threshold to be a high-viscosity nozzle. The controller acquires non-ejection information indicating an ejection disabled nozzle that is disabled to eject the ink. The controller acquires a viscosity of the ink in the ejection disabled nozzle. The controller calculates an average value of viscosities of the ink in the plurality of nozzles. The controller compares the viscosity of the ink in the ejection disabled nozzle with the average value of the viscosities of the ink in the nozzles. The controller determines whether or not to change a contribution value based on a comparison result.

  • Publication number: 20200271696
    Abstract: In the electric power converting apparatus, an electric current sensor that measures an electric current that flows through a busbar includes: a magnetic flux concentrating core that has a first end portion and a second end portion that face each other so as to have a measuring space interposed; and a magnetoelectric transducer that has a magnetically sensitive portion that is disposed in the measuring space. The magnetoelectric transducer generates a signal in response to a magnitude of a magnetic field that is sensed by the magnetically sensitive portion. Where a core opening direction of the magnetic flux concentrating core is a direction that is directed from the busbar, through the measuring space, and outward from the magnetic flux concentrating core, a direction of the magnetic leakage field at the electric reactor is a direction that is different than the core opening direction.

  • Patent number: 10690817
    Abstract: An ultra-thin planar device is used for arbitrary waveform formation on a micrometer scale, regardless of the incident light's polarization. Patterned perforations are made in a 30 nm-thick metal film, creating discrete phase shifts and forming a desired wavefront of cross-polarized, scattered light. The signal-to-noise ratio of these devices is at least one order of magnitude higher than current metallic nano-antenna designs. The focal length of a lens built on such principle can also be adjusted by changing the wavelength of the incident light. All proposed embodiments can be embedded, for example, on a chip or at the end of an optical fiber.
