20110284656 | Amazing Member and Atomizer Including the Same - An atomizing member that includes a piezoelectric vibrator and a vibrating membrane. The piezoelectric vibrator includes a cylindrical piezoelectric body, a first electrode disposed on an inner circumferential surface of the piezoelectric body, and a second electrode disposed on an outer circumferential surface of the piezoelectric body. The piezoelectric vibrator performs cylindrical breathing vibration. The vibrating membrane is disposed on an opening at a first side in an axial direction of the piezoelectric body so as to cover the opening. The vibrating membrane has a through hole in its central portion. | 11-24-2011 |
20120080981 | Piezoelectric Power Generator - A piezoelectric power generator that includes a piezoelectric laminate in which a plurality of rectangular-shaped piezoelectric elements each having electrodes formed on a substrate are connected at both ends thereof to each other, and in which a portion other than connection portions is capable of vibrating. In the piezoelectric laminate, a portion of the element at the uppermost layer is a fixed portion, and a weight is mounted to the element (free end) at the lowermost layer. Each piezoelectric element is decreased in rigidity from the element at the uppermost layer toward the element at the lowermost layer. | 04-05-2012 |
20150022059 | ELECTRONIC COMPONENT AND MANUFACTURING METHOD OF THE SAME - A method of manufacturing an electronic component includes bonding a dome-shaped cap having a recess to a substrate on which are disposed a vibrator and a bonding material projecting in a rounded shape and surrounding the vibrator while the cap is disposed so that an open side of the recess faces the substrate and is relatively pressed to the substrate side. The bonding material is disposed so that, relative to the vibrator, an outer side end portion of the cap is located on the inner side of the bonding material or an inner side end portion of the cap is located on the outer side of the bonding material. | 01-22-2015 |
20150054385 | Quartz Vibrator - A quartz vibrator that includes a substrate, a quartz vibrating element, and a dome-shaped cap. The quartz vibrating element is mounted on the substrate. The cap is bonded to the substrate. The cap defines and forms a sealed space that seals the quartz vibrating element along with the substrate. The cap has a side wall portion, a ceiling portion, and a connecting portion. The side wall portion encloses the quartz vibrating element. The ceiling portion is positioned above the quartz vibrating element. The connecting portion connects the side wall portion and the ceiling portion. The connecting portion is thinner than the side wall portion and the ceiling portion. | 02-26-2015 |
20160065173 | VIBRATING DEVICE - A vibrating device having tuning fork arms extending in a first direction that are joined to a base portion and are arranged side by side in an second direction. Each of the tuning fork arms has a structure that a silicon oxide layer is laminated on a Si layer made of a degenerate semiconductor, and that an excitation portion is provided on the silicon oxide layer. When a total thickness of the Si layer is denoted by T | 03-03-2016 |
20160072473 | VIBRATING DEVICE - A vibrating device having a number 2N (N is an integer equal to 2 or larger) of tuning fork arms extending in a first direction are arranged side by side in a second direction. Phases of flexural vibrations of the number N of tuning fork arms positioned at a first side of an imaginary line A, which passes a center of a region in the second direction where the number 2N of tuning fork arms are disposed and which extends in the first direction, are symmetric to phases of flexural vibrations of the number N of tuning fork arms positioned at a second side of the imaginary line opposite the first side. | 03-10-2016 |
20160111627 | VIBRATION DEVICE - A vibration device that includes a vibration portion, a support portion connected to the vibration portion, a bending-vibrating portion connected to the support portion, and a frame-shaped base portion connected to the bending-vibration portion and disposed so as to surround the vibration portion. The base portion defines a slit that extends in a first direction crossing a second direction in which the support portion extends from the vibration portion, the slit defining first and second fixed ends of the bending-vibrating portion and which are continuous with the base portion. A length between a portion of the bending-vibrating portion connected to the support portion to one of the first and second fixed ends of the bending-vibrating portion is in a range of λ/8 to 3λ/8, where λ denotes a wavelength of a bending vibration corresponding to a frequency of a characteristic vibration of the vibration portion. | 04-21-2016 |
20160133824 | ACTUATOR - An actuator that includes a plate-like elastic member. When seen from a first principal surface side in a plan view, the plate-like elastic member has a shape in which the elastic member extends along a circular arc-shaped center line. The plate-like elastic member is torsionally displaced relative to the circular arc-shaped center line as a central axis. | 05-12-2016 |
