  • Patent number: 9130149
    Abstract: A piezoelectric actuator of the invention includes a piezoelectric element, a base body having an upper face on which a lower end of the piezoelectric element abuts, and a case having an inner face on which an upper end of the piezoelectric element abuts, the case being configured to enclose the piezoelectric element, wherein the case includes a flange portion configured to be joined to the base body, and at least two bent portions are present on an inner face that is formed from a lower face of the flange portion of the case to the upper face of the base body on an enclosure space side of a junction between the case and the base body.
    Type: Grant

  • Patent number: 8421310
    Abstract: To provide a multi-layer piezoelectric element which is easy to be fabricated and which exhibits excellent durability, even when it is driven continuously for a long time under high electric field and high pressure. The multi-layer piezoelectric element comprising a stacked body wherein a plurality of piezoelectric layers and a plurality of metal layers are stacked alternately one on another and it is driven by applying a voltage to adjacent and opposing metal layers, wherein an average grain size of the piezoelectric crystal grains in a region of the piezoelectric layer, in which region the piezoelectric layer is sandwiched between the adjacent and opposing internal electrode in the stacking direction.

  • Patent number: 8007903
    Abstract: A ceramic member in which the metal layers with high void ratio are sufficiently sintered to lower a residue of resin is produced. The method for manufacturing a ceramic member which comprises a step of forming a stacked compact from a plurality of metallic paste layers containing a metal component M1 that are stacked one on another via ceramic green sheets, and a step of firing the stacked compact, wherein at least one of plural metallic paste layers is formed as a second metallic paste layer that has the mass percentage X higher than that of the metallic paste layer that adjoin therewith in the stacking direction and a ceramic powder is contained in the second metallic paste layer in the step of forming the stacked compact, the mass percentage X being the proportion of the metal component M1 to the total metal content in the metallic paste layer.
