  • Publication number: 20220310188
    Abstract: A storage device includes a memory, a write circuit, a read circuit, and a debug information register. The memory includes a data area and a redundant area that corresponds to the data area. The write circuit writes first data specified in a write command to the data area, and first information about a transmission source which has transmitted the write command, to the redundant area. The read circuit reads the first data as second data from the data area, and reads the first information as second information from the redundant area, in response to a read command. The debug information register stores the second information read by the read circuit.

  • Publication number: 20200027637
    Abstract: An inductor component comprising an element body formed by laminating a plurality of insulating layers, and a helically wound coil disposed in the element body. The insulating layer contains a base material and a crystal, wherein a refractive index of each of the base material and the crystal is 1.8 or less for at least one wavelength of 350 nm or more and 450 nm or less (i.e., from 350 nm to 450 nm). The coil includes a coil wiring wound along a plane, and the coil wiring is made up of one coil conductor layer or a plurality of coil conductor layers laminated in surface contact with each other. Also, the aspect ratio of the coil conductor layer is 1.0 or more.

  • Patent number: 10294145
    Abstract: A coating composition contains 5 parts by mass or more and 20 parts by mass or less (i.e., 5 to 20) of a first resin composition, 5 parts by mass or more and 20 parts by mass or less (i.e., 5 to 20) of a second resin composition, and 40 parts by mass or more and 65 parts by mass or less (i.e., 40 to 65) of an inorganic powder. The first resin composition is a poly(meth)acrylate with a glass transition temperature Tg of ??20° C., and the second resin composition is a compound having structures represented by general formulae (1) and (2), below, one or more structures for each. R1, in general formula (1), and R2, in general formula (2), are each independently a hydrogen atom or a methyl group. X, in general formula (2), is any substituent that is not a hydrogen atom.

  • Publication number: 20190088414
    Abstract: A method of manufacturing an inductor component includes preparing an insulating paste that is photosensitive and that includes a filler material composed of quartz, a glass material and a resin material, and a conductive paste, forming a first insulating layer by applying the insulating paste, and exposing the first insulating layer in a state where a first portion of the first insulating layer is shielded by a mask. The method further includes removing the first portion of the first insulating layer to form a groove at a position corresponding to the first portion, applying the conductive paste in the groove to form a coil conductor layer in the groove, and applying the insulating paste on the first insulating layer and the coil conductor layer to form a second insulating layer.

  • Patent number: 10192650
    Abstract: A photosensitive conductive paste that contains (a) a conductive powder in an amount of 70.3 to 85.6 mass % with respect to the total amount of the photosensitive conductive paste; (b) a photosensitive resin composition containing an alkali-soluble polymer, a photosensitive monomer, a photopolymerization initiator, and a solvent; and (c) a glass frit. The mass ratio of the glass frit to the conductive powder is 0.020 to 0.054, and the glass frit has a softening point that is equal to or above the temperature at which sintering of the conductive powder starts.
