Patent number: 10006452Abstract: In a method for adjusting a fluid control apparatus, in a pressing step, a piezoelectric pump is placed on a stage with a cover plate facing upward, the stage is moved up, and a center portion of a principal surface of the cover plate on a side opposite to a diaphragm is pressed with a pressing pin. As a result, the cover plate and the base plate are shaped so as to warp convexly toward the diaphragm side, and a portion joined to a flexible plate is pulled, such that the flexible plate is caused to warp convexly toward the diaphragm side. Thus, residual tensile stress occurs in a movable portion of the flexible plate. Therefore, due to the residual tensile stress, the tensile stress of the movable portion of the flexible plate is increased.Type: GrantFiled: July 26, 2013Date of Patent: June 26, 2018Assignee: Murata Manufacturing Co., Ltd.Inventors: Atsuhiko Hirata, Kenta Omori

Patent number: 8747080Abstract: A small-sized, low-profile fluid pump having high pumping capabilities includes an actuator and a planar section including a metal plate. The actuator includes a disk-shaped piezoelectric element attached to a disk-shaped diaphragm. As a result of application of a square-wave or sine-wave drive voltage, the actuator performs a bending vibration from the central portion to the peripheral portion. The peripheral portion of the actuator is not restrained. The actuator performs a bending vibration in the state in which it is in proximity to the planar section while facing the planar section. A center vent is provided at or in an area adjacent to the center of an actuator facing area of the planar section that faces the actuator.Type: GrantFiled: March 13, 2012Date of Patent: June 10, 2014Assignee: Murata Manufacturing Co., Ltd.Inventors: Yukiharu Kodama, Atsuhiko Hirata, Kenta Omori
