  • Publication number: 20210020376
    Abstract: A multilayer electronic component having a plurality of laminated dielectric layers and inner electrode layers. The dielectric layers have a plurality of crystal grains including first regions where Re is dissolved in a solid state; and second regions where Re is not dissolved in the solid state. A median size of the crystal grains to an average thickness of the dielectric layers is 0.5?t?0.7. A ratio of a sum of cross sectional areas of the first regions to those of the plurality of crystal grains is 0.7?s?0.9. When a total amount of Ti, Zr, and Hf is 100 molar parts in the dielectric layers, a sum of the Zr and the Hf is 0?a?1.0; an amount b of Si is 0.1?b?1.0; an amount c of Re is 0.5?c?10.0; and a ratio m of a total of Ba and Re to a total of Ti, Zr, and Hf is 0.990?m?1.050.

  • Publication number: 20200409138
    Abstract: An optical deflector capable of making a swing angle of a reflective plate larger is provided. In drive elements, since a size in the Y direction at first positions separated by a first distance from the reflective plate is larger than a size in the Y direction at second positions separated by a second distance from the reflective plate, the second distance being greater than the first distance, it is possible to increase displacement of tips of beam portions at the first positions and to make a swing angle of the reflective plate large by increasing a generated force of the entire beam portions.

  • Patent number: 10875558
    Abstract: When there is a train entering a building of a rail yard, a ground apparatus stores vehicle-formation-set IDs of respective vehicle-formation-sets of the train in the entering order by a FILO method. Additionally, when there is the train leaving the building, the vehicle-formation-set IDs are sequentially read by the FILO method, an inquiry addressed to the vehicle-formation-set IDs is transmitted in the order of the reading to obtain the train information from the on-board apparatus of each of the vehicle-formation-sets forming the train. When the on-board apparatus does not respond to the inquiry, and obtaining of the train information fails, the ground apparatus performs a predetermined alarm output control.

  • Patent number: 10781529
    Abstract: Anodizing techniques for providing highly opaque colorized anodic films are described. According to some embodiments, the methods involve depositing a pigment having a particle diameter of about 20 nanometers or greater into an anodic film. Additionally or alternatively, a barrier layer smoothing operation is used to flatten an interface between the anodic film and underlying metal substrate so as to maximize light reflection off the interface, thereby maximizing light reflected off the pigment that is deposited within pores of the anodic film. The resulting anodic films have an opaque or saturated colored appearance. In some embodiments, the methods involve increasing a thickness of a non-porous barrier layer of the anodic film so as to create thin film interference effects that can add a particular hue to the anodic film. The methods can be used form cosmetically appealing coatings for consumer products, such as housings for electronic products.

  • Patent number: 10760175
    Abstract: Anodic films that have a white color, and methods for forming the same, are described. According to some embodiments, the anodic films have multiple metal oxide layers. A first layer can provide scratch and chemical resistance and a second layer can provide a light diffusing pore structure that diffusely reflects incoming light and provides a white appearance to the anodic film. According to some embodiments, the anodic films also include a smoothed barrier layer that specularly reflects incoming light so as to brighten the appearance and enhance the white color of the anodic film. The resulting anodic films have an opaque white appearance not achievable using conventional techniques. The anodic films are well suited for providing cosmetically appealing coatings for consumer products, such as housings for electronic products.
