  • Patent number: 10395828
    Abstract: The dielectric layers are formed from a dielectric porcelain formed from crystal particles containing barium titanate as a main component and containing a rare earth element, and the crystal particles have, in a particle boundary vicinity, a low concentration region in which the concentration of the rare earth element is lower than the concentration of the rare earth element in an inside. The crystal particles further contain vanadium, and the low concentration region contains a larger amount of the vanadium than the amount of the vanadium in the inside. The crystal particles further contain magnesium and manganese, and the magnesium and the manganese have a concentration gradient that is at a maximum at the particle boundary vicinity and that lowers toward the inside.

  • Patent number: 10379069
    Abstract: A magnetism measuring device includes a light source unit, a diamond crystal and an image sensor. The light source unit irradiates the diamond crystal with an excitation light, and irradiates the image sensor with a fluorescent light generated by the diamond crystal. The diamond crystal includes a plurality of nitrogen-vacancy pairs. The image sensor detects an intensity of the fluorescent light, which is generated from the diamond crystal, by a plurality of pixels. The image sensor and the light source unit are disposed so as to be contained within a projection area of the diamond crystal.

  • Patent number: 10098179
    Abstract: A compact electronic device as a constituent element of a wireless communication system using a sensor. A first feature of the device is that a first semiconductor chip is bare-chip-mounted over a front surface of a first wiring board in the form of a chip and a second semiconductor chip is bare-chip-mounted over a second wiring board in the form of a chip. A second feature is that a wireless communication unit and a data processing unit which configure a module are separately mounted. A third feature is that the first and second wiring boards are stacked in the board thickness direction to make up the module (electronic device).

  • Publication number: 20160313408
    Abstract: A magnetic measuring device can be downsized. The magnetic measuring device includes a diamond crystal, a microwave source, a light source array/microwave circuit chip, an image sensor, and a signal controller. The diamond crystal contains a plurality of nitrogen-vacancy pairs. The microwave source generates the microwave that is irradiated to the diamond crystal. The microwave circuit unit in the light source array/microwave circuit chip irradiates the diamond crystal with the microwave. The light source array in the light source array/microwave circuit chip irradiates the diamond crystal with excitation light. The image sensor detects an intensity of fluorescent light generated from the diamond crystal. The signal controller performs image processing of a fluorescent image taken-in by the image sensor, and controls operations of the light source array/microwave circuit chip and the microwave source.

  • Patent number: 8420559
    Abstract: Disclosed is a multilayer ceramic capacitor which is formed by alternately laminating (i) dielectric layers composed of a dielectric ceramic and (ii) internal electrode layers. The dielectric ceramic is composed of crystal grains mainly composed of barium titanate, while containing predetermined amounts of magnesium, vanadium, manganese and terbium, and at least one rare earth element selected from yttrium, dysprosium, holmium and erbium. In an x-ray diffraction chart of the dielectric ceramic, the diffraction intensity of the (200) plane indicating cubic barium titanate is higher than the diffraction intensity of the (002) plane indicating tetragonal barium titanate. The dielectric ceramic has a Curie temperature of 110-120° C.
