    • When a cavity accommodating movable portion of an external force detecting sensor has a narrow structure, the external force detecting sensor is influenced by air damping, and therefore the cavity should have a wide structure. However, when a top surface and bottom surface of the cavity are positioned too high, the range of vertical movement of the movable portion is increased, and when an external impact force is applied to the external force detecting sensor, a movable interdigitated electrode rides on fixed interdigitated electrodes and stays there, thus the external force detecting sensor is rendered inoperable. A height D from the fixed interdigitated electrodes to the top surface and bottom surface of the cavity is set by having, as elements, widths of the movable interdigitated electrode, and fixed interdigitated electrodes set to W1, W2, and W3, the height of the movable interdigitated electrode and fixed interdigitated electrodes set to h, and gaps between the movable interdigitated electrode and fixed interdigitated electrodes set to g1 and g2, and the movable portion is structured so as to securely return to the standstill position due to resiliency of a beam.
    • 当外力检测传感器的容纳腔的可动部具有窄结构时,外力检测传感器受到空气阻尼的影响,因此空腔应具有宽的结构。 然而,当空腔的上表面和底表面位置太高时,可移动部分的垂直移动范围增加,并且当外部冲击力施加到外力检测传感器时,可移动叉指电极 固定的叉指电极并停留在那里,因此外力检测传感器不可操作。 通过将可移动叉指电极的宽度和固定叉指电极设置为W 1 ,W 2 和W 3 ,可移动叉指电极和固定叉指电极的高度 至h,并且可动交叉电极和固定叉指电极之间的间隙设置为g 1 和g 2 , 可移动部分被构造成由于梁的弹性而牢固地返回到停止位置

    • A piezoelectric filter that includes a first substrate having at least one first piezoelectric resonator disposed on a main surface thereof; a second substrate having at least one second piezoelectric resonator disposed on a main surface thereof. A connection pattern extends around the first piezoelectric resonator and the second piezoelectric resonator and is disposed between the first substrate and the second substrate such that the main surface of the first substrate faces the main surface of the second substrate, and the first piezoelectric resonator is remote from the second piezoelectric resonator. A connecting layer bonds a pad disposed on the main surface of the first substrate to a pad disposed on the main surface of the second substrate, and is electrically connected to the first piezoelectric resonator and the second piezoelectric resonator.

    • A vibrator includes: a vibrating body; a driving unit for causing the vibrating body to vibrate in a predetermined vibrating direction; and a driving monitoring unit for detecting vibration displacement in a driving direction of the vibrating body. Stabilization of vibration in the driving direction of the vibrating body is achieved by applying positive feedback control to the driving unit based on the state of the vibration displacement in the driving direction of the vibrating body detected by this driving monitoring unit. The driving monitoring unit is constructed and arranged so as to be provided in a barycentric region of the vibrating body to detect the vibration displacement in the driving direction of the barycentric region of the vibrating body.
