Between the terminals next to each other, a plurality of grooves spaced apart in a predetermined direction and extending in a direction intersecting the predetermined direction are disposed. | 05-23-2013 |
20130192367 | VIBRATOR ELEMENT, VIBRATING DEVICE, PHYSICAL QUANTITY DETECTING DEVICE, AND ELECTRONIC APPARATUS - A first support portion, which is connected to a first beam extending from a vibrating body and supports the vibrating body, and a detection signal terminal and a detection ground terminal, which are provided in the first support portion and are arranged in parallel so as to be separated from each other along a direction crossing an extending direction of the first beam, are provided. The first beam and the first support portion are connected between the detection signal terminal and the detection ground terminal. A thin portion formed to have a small thickness in a top to bottom direction of the first support portion or a penetrating portion formed by removing the first support portion so as to be penetrated in the top to bottom direction is provided between the detection signal terminal and the detection ground terminal. | 08-01-2013 |
20130320812 | VIBRATING REED, ELECTRONIC DEVICE, AND ELECTRONIC APPARATUS - A vibrating reed includes a vibrating body (a base portion, a vibrating arm, and a detection arm) and a support portion that supports the vibrating body via a plate-like coupling portion. In both principal surfaces of the coupling portion, grooves (a first groove and a second groove) are disposed. The first groove arranged in one of the principal surfaces of the coupling portion and the second groove arranged in the other principal surface are arranged at positions different from each other in plan view. | 12-05-2013 |
20130320816 | VIBRATOR ELEMENT, ELECTRONIC DEVICE, ELECTRONIC APPARATUS, AND METHOD OF MANUFACTURING VIBRATOR ELEMENT - A vibrator element includes a base section, and a vibrating arm projecting from the base section, and having a plurality of groove sections, the vibrating arm is provided with the groove sections, and the groove sections are each formed to have a length in a width direction of the vibrating arm longer than a length in a longitudinal direction of the vibrating arm, and arranged side by side along the longitudinal direction of the vibrating arm. | 12-05-2013 |
20140020503 | VIBRATOR ELEMENT, METHOD OF MANUFACTURING VIBRATOR ELEMENT, VIBRATOR, ELECTRONIC DEVICE, ELECTRONIC APPARATUS AND MOVING BODY - A vibrator element includes a pair of first and second drive vibrating arms that extend in opposite directions from a base portion; a first weight that is spaced from a tip of at least one of the first and second drive vibrating arms toward the base portion and is provided in a first region of the at least one of the drive vibrating arms; and a second weight that is provided in a second region that is a region between a tip of the first weight and the tip of the at least one of the drive vibrating arms. When an area of the first region is represented as A1, a mass of the first weight is represented as B1, an area of the second region is represented as A2, and a mass of the second weight is represented as B2, B1/A1>B2/A2 is established. | 01-23-2014 |
20140077664 | VIBRATOR ELEMENT, VIBRATOR, ELECTRONIC DEVICE, ELECTRONIC APPARATUS, AND MOVING OBJECT - A gyro element as a vibrator element fulfills the relationship: |fd−fy1|>|fd−fy2|, where fd is a drive vibrational frequency of first through fourth drive vibration arms, fy1 is a y1-mode vibrational frequency of a y1 mode, in which a base section and the first through fourth drive vibration arms vibrate in the same direction along a first direction (a y-axis direction) in which the first drive vibration arm extends, and fy2 is a y2-mode vibrational frequency of a y2 mode in which the base section vibrates along the first direction and the first through fourth drive vibration arms vibrate along the first direction in an opposite direction to a direction in which the base section vibrates. | 03-20-2014 |
20150162522 | VIBRATION ELEMENT, VIBRATOR, VIBRATION DEVICE, ELECTRONIC DEVICE AND MOVING OBJECT - A vibration element includes a vibrating portion, a support portion that supports the vibrating portion, and a suspension arm that couples the vibrating portion to the support portion. In addition, the suspension arm includes a meandering portion extending out the support portion and an inclination portion that couples the meandering portion to the vibrating portion. | 06-11-2015 |
20150268107 | PHYSICAL QUANTITY DETECTING DEVICE, ELECTRONIC APPARATUS, AND MOVING OBJECT - A physical quantity detecting device includes a vibrating element and a charge amplifier.
