    • 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.

    • In an electron source manufacturing method and apparatus, a plurality of electron-emitting devices are commonly connected to a first wiring and to a plurality of second wirings, respectively. A voltage V1 is applied to the plurality of devices connected to the first wiring by the difference between potentials applied to the first wiring and the plurality of second wirings. The voltage V1 has a relationship with a maximum value V2 of a voltage applied as a normal driving voltage after the voltage application step, so as to satisfy: giving a current I flowing upon application of the voltage V when a voltage V falling within a voltage range causing electron emission upon application of the voltage between the two electrodes of each device is applied to the device: I=f(V)  (1) and letting f′(V) be the differential coefficient of f(V) at the voltage V, a condition: f(V1)/{V1·f′(V1)−2f(V1)}>f(V2)/{V2·f′(V2)−2f(V2)}  (2) In this manner, the potential applied to each second wiring is set to reduce the difference in magnitude of the voltage V1 applied to each device connected to the first wiring.
