20100242242 | METHOD FOR MANUFACTURING PIEZOELECTRIC ACTUATOR - There is provided a method for manufacturing a piezoelectric actuator where the planar shape is adjusted by subjecting the piezoelectric body layer located on one of the outer surfaces in the two or more piezoelectric body layers to a polarization treatment to control remnant polarization of the piezoelectric body layer. The piezoelectric actuator is used as a drive portion of a piezoelectric drive type variable capacitor. The variable capacitor has high mechanical strength and excellent reliability for a long period of time. The relation between the displacement amount of the piezoelectric actuator and the capacity of the capacitor is stable, and the variable capacity is wide. | 09-30-2010 |
20110014362 | METHOD FOR PRODUCING CRYSTALLINE PARTICLES AND METHOD FOR PRODUCING CRYSTALLOGRAPHICALLY ORIENTED CERAMIC - A method for producing crystalline particles according to the present invention includes a mixing step of producing a mixed material containing a lead-containing material and an additional material containing lithium and boron and a first firing step of firing the mixed material at a predetermined firing temperature to form polyhedral crystalline particles. It is possible to produce a crystallographically oriented ceramic by preparing a template layer having uniform crystal orientation in a predetermined direction by fixing the crystalline particles on a substrate, forming a shaped body including a matrix layer arranged on the template layer, the matrix layer being composed of a mixed material that contains a lead-containing material and an additional material containing lithium and boron, and firing the shaped body. | 01-20-2011 |

20120000595 | METHOD FOR MANUFACTURING A DROPLET DISCHARGE HEAD - In a method for manufacturing a droplet discharge head, a first mold is prepared having first convexity portions shaped like pressure chambers of the droplet discharge head. A slurry is filled into the first mold, and the first mold is placed on a first porous plate. A solvent included in the slurry permeates into the first porous plate. The slurry is dried to form a first compact. Similarly, a second mold is prepared which has second convexity portions shaped like nozzle sections of the droplet discharge head. The slurry is filled into the second mold, and the second mold is placed on a second porous plate. The solvent included in the slurry permeates into the second porous plate. The slurry is dried to form a second compact. Thereafter, the first compact and the second compact are press bonded and fired. | 01-05-2012 |
