  • Publication number: 20240177936
    Abstract: A multilayer electronic device includes an element body including an interior region and an exterior region and a pair of external electrodes. The interior region includes inner dielectric layers and internal electrode layers laminated alternately. The exterior region is disposed outwards from the interior region in a lamination direction. The pair of external electrodes is disposed on a surface of the element body and connected to the internal electrode layers. DRAa<DRAb<DRAc and DRBa>DRBb>DRBc are satisfied, where “RA” includes an element having a highest mole ratio among “RE” in the inner dielectric layers of a third region at a center of the interior region in the lamination direction, “RB” includes an element having a highest mole ratio among “RE” in a first region at a center of the exterior region in the lamination direction, and “RA” and “RB” are different from each other.

  • Publication number: 20240169097
    Abstract: A data authenticity proving system calculates a hash value A and a hash value B from an evidence data transmitted from a terminal device at respectively different timings, and, when the hash value A and the hash value B are the same, registers the evidence data by storing the evidence data in a storage device. In case that the evidence data has been tampered with during a time between a timing of receiving the evidence data from the terminal device and a timing of registering the evidence data in the storage device, the hash value A and the hash value B take respectively different values, thereby registration of the evidence data will not be performed.

  • Publication number: 20240167117
    Abstract: A method for producing a hot-rolled steel sheet which enables predicting a temperature history of unevenness of the end face of a coil includes: measuring a surface temperature of hot-rolled strip-shaped steel; calculating a temperature history in a natural cooling state after coiling, assuming that the strip-shaped steel has been coiled without unevenness on an end face, based on the surface temperature measured in the measurement step; actually coiling the strip-shaped steel after the measurement step; scanning with a displacement meter, an end face of a coil formed in the coiling step, and deriving a size of the unevenness of the end face over a radius of the coil; and predicting a temperature history of the unevenness in a natural cooling state using: the temperature history calculated in the first calculation step; and the size of the unevenness derived in the derivation step.

The R element is one or more elements selected from Eu, Gd, Tb, Dy, Y, Ho, and Yb. The M element is one or more elements selected from Mg, Ca, Mn, V, and Cr. A ratio of an amount of the oxide of the R element in terms of R2O3 to an amount of the oxide containing Si in terms of SiO2 is 0.8:1 to 2.2:1. A ratio of an amount of the oxide of the M element in terms of MO to the amount of the oxide containing Si in terms of SiO2 is 0.2:1 to 1.8:1.50% or more of the number of dielectric particles constituting the dielectric ceramic composition is core-shell dielectric particles having a core-shell structure.
