    • A capacitor type acceleration sensor is disclosed. In this sensor, an acceleration sensing element 1 has two variable capacitors C1 and C2 that are constructed with a couple of fixed electrodes and a movable electrode located between the fixed electrodes. Electrostatic power generation/feedback means 15 applies to the fixed- and movable-electrode pairs such an electrostatic power as to set the movable electrode at a preset reference position in accordance with the output signal of capacitance-difference detector means 10. The electrostatic power is outputted as an output signal of the capacitor type acceleration sensor. In the capacitor type acceleration sensor, another fixed capacitor Cx of which the capacitance value Cx is larger than the maximum capacitance-difference between the variable capacitors C1 and C2 of which the capacitance values vary in accordance with an acceleration, is connected in parallel with the variable capacitor C2. The capacitance (C2+Cx) is larger than the capacitance of the variable capacitor C1, irrespective of the direction of acceleration.

    • Adherence between a sealing material and a glass substrate is assured, thereby improving airtightness of a hermetic container. A manufacturing method of the hermetic container has: an assembling step of sealing a first glass substrate and a second glass substrate through a circumferential sealing material having plural straight line portions and plural coupling portions which connect the plural straight line portions so as to define an internal space between the first glass substrate and the second glass substrate; and a sealing step of maintaining the internal space to a negative pressure to an outside after the assembling step, applying such local force as to compress the coupling portions of the circumferential sealing material in a thickness direction of the sealing material, and heating and melting the sealing material by irradiating local heating light to the sealing material, to seal the first glass substrate and the second glass substrate.
