  • Patent number: 11125509
    Abstract: A heat storage system using a heat storage container having a tubular body, an adsorbent that is accommodated in the tubular body, generates heat by adsorption of an adsorbate and absorbs heat by desorption of the adsorbate, and a flow channel that penetrates the tubular body in a longitudinal direction, the heat storage system comprising a diffusion layer for transporting the adsorbate in liquid phase from the flow channel to the adsorbent, wherein the adsorbate is transported to the flow channel, the adsorbate is transported to the diffusion layer, a part of the adsorbate transported to the diffusion layer is adsorbed on the adsorbent, the adsorbent releases heat, and the remaining adsorbate is vaporized by the heat to become heat transport fluid.

  • Publication number: 20210233741
    Abstract: An observation apparatus and method that avoids drawbacks of a Lorentz method and observes a weak scatterer or a phase object with in-focus, high resolution, and no azimuth dependency, by a Foucault method observation using a hollow-cone illumination that orbits and illuminates an incident electron beam having a predetermined inclination angle, an electron wave is converged at a position (height) of an aperture plate downstream of a sample and a bright field condition in which a direct transmitted electron wave of the sample passes through the aperture plate, a dark field condition in which the transmitted electron wave is shielded and a Schlieren condition in which approximately half of the transmitted wave is shielded as a boundary condition of both of the above conditions are controlled, and a spatial resolution of the observation image is controlled by selecting multiple diameters and shapes of the opening of the aperture plate.

  • Patent number: 11024482
    Abstract: A lensless Fourier transform holography high accuracy reconstruction method using a charged particle beam apparatus which holds a sample on a diffraction surface of a diffraction grating provided on the downstream side of a traveling direction of the charged particle beam and which is formed of a material having permeability. The charged particle beam passed through the diffraction surface is image-formed, and the formed image is detected. An opening region of the diffraction grating is smaller than an irradiation region of the charged particle beam on the diffraction grating. Image data is obtained in a state where the irradiation region of the charged particle beam diffracted with the diffraction grating is within the irradiation region of the charged particle beam transmitted through the diffraction grating. Plural holograms obtained based on the image data are Fourier transformed and an intensity distribution image is displayed and stored.

  • Patent number: 10948426
    Abstract: The density difference of particle beam irradiation with two optical statuses is produced utilizing a diffraction effect, within the same field of vision, such that a diffraction grating manufactured with a material which passes through a particle beam is provided on the upper side of a specimen and on the lower side of the irradiation optical system. Further, a region wider than the opening region of the diffraction grating is irradiated with the particle beam to produce the density difference of the particle beam emitted to the specimen, by superposing the particle beam, Bragg-diffracted with the opening region, and the particle beam, transmitted through the outer peripheral part of the opening region without being diffracted, with each other, and emitting the beam to the specimen.

  • Patent number: 10770264
    Abstract: An interference optical system unit includes at least one electromagnetic lens that forms an image of a charged particle beam, at least one charged particle beam biprism, and a support member for the electromagnetic lens and the charged particle beam biprism. The electromagnetic lens, the charged particle beam biprism, the support member, and a space to an image plane of the electromagnetic lens are integrally configured as one unit. The interference optical system unit is disposed to have an optical axis coaxialized with an optical axis of an imaging optical system of an upstream stage that is disposed on an upstream side of the unit in a flow direction of the charged particle beam. A focal length of the electromagnetic lens and a deflection angle of the charged particle beam given by the charged particle beam biprism are controlled to generate an interference fringe of the charged particle beam on the image plane of the electromagnetic lens.

  • Publication number: 20060068797
    Abstract: When a communication usage fee of a mobile communication terminal exceed a maximum charge, a mobile communication network side is made to manage a connection destination of the mobile communication terminal. When a mobile communication network receives a connection request message sent from a cell phone, it transmits a phone number of the cell phone to a subscriber information server and acquires usage information thereof. When the usage information is determined to be information indicating that the usage fee of cell phone has already arrived at the maximum charge, the mobile communication network sets maximum arrival information in the connection request message and transmits it to a connection management server. When it is determined that the maximum arrival information is set in the connection request message, the connection management server restricts the connection destination of cell phone to predetermined specific connection destination addresses.
