摘要： A method for manufacturing a quartz oscillator in which a quartz piece is ground as small, thin, and accurate as possible as to obtain a quartz oscillator, a quartz resonator or an optical lens for transmission and reception of a high frequency wave. An object (4) to be ground is bonded to a cylindrical, square or similar-shaped magnet plate (51) with adhesive (14) such as colophonium, resin of the mixture of colophonium and wax. The magnet plate (51) with the object (4) is directly attached to a chuck (3) made of magnetic material such as iron with adhesive (14) or another mean by using the magnetic force of the magnet plate (51), and the object (4) is ground to fabricate a quartz oscillator. An apparatus for manufacturing a quartz oscillator, comprises a magnet plate consisting of a permanent magnet or an electromagnet, a holder which holds at its tip a spherical grindstone which has a grindstone surface of diamond, etc. on its surface for grinding an object bonded to the magnet plate, and a driver which turns the holder around the axis passing the center of the spherical grindstone.

摘要： A lens-line type piezoelectric device thinner than the manufacture limit thickness, which is conventionally difficult to manufacture, and a method for manufacturing the same. The piezoelectric device has a vibrating part of at least two steps where one side thereof is planar and the opposite side is thickest at the peripheral holding portion and thinner toward the central portion. A piezoelectric element of another mode has a vibrating portion of at least two steps where the peripheral holding portion is thickest on both sides and the thickness decreases toward the central portion. In these piezoelectric devices, at least at least one side of the thinnest central portion of the vibrating part has a convex lens shape. A pair of electrodes are vacuum deposited in the center these vibrating parts on both sides, and a gold wire is led as a lead wire from each electrode.
