  • Patent number: 10546693
    Abstract: In an embodiment, a multilayer ceramic capacitor 10 is constituted in such a way that its capacitor body 11 houses a capacitance part which is halved in the third direction d3, along a shared internal electrode layer 11a3 serving as a boundary, into a high-capacitance part HC and a low-capacitance part LC. When the capacitor body 11 is cut along a surface crossing at right angles with the first direction d1, the revealed cross-sectional shape of the shared internal electrode layer 11a3 has a cross-sectional shape where a curved part CP that projects toward the dielectric layer 11b2 on low-capacitance part LC side adjoining the shared internal electrode layer 11a3, is present on both sides in the second direction d2, and also in between.

  • Patent number: 10151656
    Abstract: A pressure sensor includes a pressure sensor element, a joint provided to a target member, and an attachment member that is fitted into the joint through the connection section and connected to the target member. Each of the pressure sensor element and the joint is formed of a material that is not embrittled upon being in contact with a fluid to be measured that embrittles a material, and more rigid than the attachment member. The connection section is subjected to a plastic deformation connection (metal flow). An expensive hydrogen embrittlement resistant material is used for the pressure sensor element and the joint that are brought into contact with the fluid to be measured, and an inexpensive material is used for the attachment member that is not brought into contact with the fluid to be measured, thereby reducing the production cost of the pressure sensor.
