  • Patent number: 11671007
    Abstract: A plurality of switching units are provided, and a controller performs control in an antiphase manner to approximately synchronize a rise of a control signal applied to one of the switching units with a fall of a control signal for switching applied to any one of the other switching units and synchronize a fall of the control signal applied to the one of the switching units with a rise of the control signal for switching applied to the any one of the other switching units. When control in an antiphase manner is disabled, control is performed to prevent rises or falls from coinciding with each other between the switching units. Output signals from the switching units are input to rectifiers and are combined by a combiner to become an output signal.

  • Publication number: 20230166010
    Abstract: A high-nitrogen nickel-free austenitic stainless steel seamless thin-walled tube, a high-safety nickel-free metal-based drug-eluting vascular stent manufactured therefrom, and manufacturing methods therefor. In the process of manufacturing a stent tube, the nitrogen content of a material is further increased by means of stage-by-stage nitriding, so as to obtain a high-nitrogen nickel-free austenitic stainless steel seamless thin-walled tube having the nitrogen content of 0.8-1.2% as a metal stent platform material. By using rolling line contact type electrochemical polishing, the surface of the stent forms a micron-scale protrusion-recess structure by means of crystal grains having different orientations, thus improving a binding force between a metal stent material and a drug coating. The vascular stent has the characteristics of high fatigue life, high biological safety, and a high binding force between the drug coating and a substrate.

  • Publication number: 20230077782
    Abstract: The color of an electrochromic stack in a tinted state may be modified to achieve a desired color target by utilizing various techniques alone or in combination. A first approach generally involves changing a coloration efficiency of a WOx electrochromic (EC) layer by lowering a sputter temperature to achieve a WOx microstructural change in the EC layer. A second approach generally involves utilizing a dopant (e.g., Mo, Nb, or V) to improve the neutrality of the tinted state of WOx (coloration efficiency changes). A third approach generally involves tailoring a thickness of the WOx layer to tune the color of the tinted stack.

  • Publication number: 20230059414
    Abstract: A method of setting a parameter of a charged particle beam device, for shortening the time required to adjust an ABCC parameter. An inverse conversion processing unit generates a simulator input signal corresponding to an electron emitted from a sample. A simulation detector uses an arithmetic model that simulates a detector and executes arithmetic processing on the simulator input signal in a state in which characteristic information is reflected in an arithmetic parameter. A simulated image conversion unit executes arithmetic processing corresponding to an image conversion unit and converts a signal from the simulation detector into a simulated image. An ABCC search unit searches for an ABCC parameter with respect to the simulation detector so that an evaluation value obtained from the simulated image becomes a specified reference value, and outputs the ABCC parameter as a search result to an ABCC control unit of the actual machine.

  • Patent number: 11579099
    Abstract: This disclosure relates to an apparatus and methods for applying X-ray reflectometry (XRR) in characterizing three dimensional nanostructures supported on a flat substrate with a miniscule sampling area and a thickness in nanometers. In particular, this disclosure is targeted for addressing the difficulties encountered when XRR is applied to samples with intricate nanostructures along all three directions, e.g. arrays of nanostructured poles or shafts. Convergent X-ray with long wavelength, greater than that from a copper anode of 0.154 nm and less than twice of the characteristic dimensions along the film thickness direction, is preferably used with appropriate collimations on both incident and detection arms to enable the XRR for measurements of samples with limited sample area and scattering volumes.
