  • Patent number: 8847244
    Abstract: A photpcoupler includes: a light emitting element; a first photodiode array; a second photodiode array; a third photo diode array; an enhancement-mode MOSFET; a first depletion-mode MOSFET; and a second depletion mode MOSFET. The light emitting element converts the input electrical signal into the optical signal. A drain current of the enhancement-mode MOSFET is supplied to the external load when the optical signal is ON. A drain current of the first depletion-mode MOSFET is supplied to the external load when the optical signal is OFF and a voltage passing through the second depletion-mode MOSFET switched to the ON state is supplied to the gate of the first depletion-mode MOSFET. And the drain current of the first depletion-mode MOSFET is larger than a drain current of the first depletion-mode MOSFET when a gate voltage of the first depletion-mode MOSFET is zero.

  • Patent number: 8633794
    Abstract: An electronic component and manufacturing method for preparing an electronic component includes providing a first insulator layer having a first nickel content rate. A coil conductor and a second insulator layer having a first bismuth content rate and a second nickel content rate higher than the first nickel content rate are provided on the first insulator layer. The first insulator layer, the coil conductor, and the second insulator layer constitute a first unit layer. The first unit layer and an exterior insulator layer are laminated to obtain a laminate. After a step of firing the laminate, a nickel content rate in a first portion of the first insulator layer, the first portion being sandwiched between the coil conductors from both sides facing in a lamination direction, is lower than a nickel content rate in a second portion of the first insulator layer other than the first portion.

  • Patent number: 8265381
    Abstract: To provide a sign authentication system and method for authenticating the originality of an object having a sign such as a seal or a signature or a pattern which can be deemed as a sign, making counterfeit very difficult even if the mechanism of authentication is revealed, obviating the need for being additionally provided with a special device such as an IC chip used for authenticating the originality. A sign authentication system provides reading a sign such as a personal seal impression as color information for each mesh division, extracting feature points from the color information and storing them, and creating a code for authentication from the feature points. The sign is made with an ink containing color material particles smaller than the mesh division. The feature points on the basis of variation of color information caused are extracted when the mesh division is shifted.

  • Patent number: 7828919
    Abstract: A method for manufacturing a multilayer ceramic electronic component can prevent the occurrence of bubble trapping. In the method, when an external layer ceramic green sheet is pressure-bonded, for example, to a sheet made of a good quality paper having a rough surface, which is placed on a supporting member, followed by peeling off its carrier film, a first-layer ceramic green sheet is formed. The first-layer external layer ceramic green sheet uses a sterically hindered dispersing agent, such as an aryl ether polymer, as a dispersing agent. Since it is light in weight, the binder segregates at the upper side, and hence a C concentration changes in the thickness direction. More particularly, compared to a C concentration at a surface at a carrier film side supported by the carrier film, a C concentration at an open surface opposite to the surface at the carrier film side is about 1.5 to about 4.0 times.

  • Patent number: 7474191
    Abstract: A layered coil component includes a coil that is constructed by layering coil conductor patterns and ceramic sheets. The ceramic sheets include a first ceramic sheet and a third ceramic sheet having a permeability lower than the permeability of the first ceramic sheet. The third ceramic sheet has an arrangement that is astride at least two of the coil conductor patterns adjacent to each other in a layering direction, in a section including a coil axis of the coil. As a result, DC bias characteristics of the open magnetic circuit type layered coil component are improved.
