摘要： The shape of a crotch portion of a tuning fork of a quartz piece is controlled such that main surfaces of two sheets of original plates, which are made of quartz crystal and the main surfaces thereof are orthogonal to the direction of the Z axis, which is a crystal axis, are bonded so that the plus/minus directions of the X axis, which is another crystal axis, are made in a reverse relation to each other to form a quartz substrate, and masks for forming the outer shape, through which the surfaces of the quartz substrate are exposed, are formed on both front and back surfaces of the quartz substrate in a manner that the mask follows along the outer shape of the quartz piece and the width direction of the outer shape agrees with the X axis, and the quartz substrate is etched to form the outer shape of the quartz piece.

摘要： A permanent magnet generator incorporated in a diskette that can be inserted into a floppy disk drive is disclosed. In the permanent magnet generator, electric power is generated as a rotor is caused to rotate at a revolution twice to ten times as high as that of the drive shaft of a floppy disk drive by transmitting the rotation of the drive shaft to a rotor via a speed increasing mechanism incorporated in a diskette. Since the cogging torque of the generator is reduced, the rotor can be caused to rotate with a small drive torque. This allows the generator to produce a high output.

摘要： A first metal film is formed on a piezoelectric substrate surface. A pattern of openings forming a first resist mask is formed in the first metal film. Portions of the metal film are removed by etching. The substrate is brought into contact with a first etching solution to remove substrate material to shape an outer surface. After, openings in the first metal film are filled in with a second metal film. The substrate is shaped into a first plurality of piezoelectric resonators using a second etching solution. Rough frequency adjustment is conducted by etching side surfaces of the substrate in increments and cutting a piezoelectric resonator from the substrate. The rough frequency adjustment continues until a measured oscillation frequency is within a predetermined frequency range. Electrode patterns then are formed for each one of the second plurality of piezoelectric resonators.

摘要： Quartz-crystal vibrating devices are disclosed, including vibrating and frame portions separated by a through-slot. An edge surface of the slot has a protrusion preventing unwanted formation of artifact “electrodes.” The vibrating portion and frame are made of AT-cut quartz as a unit. A joining portion couples the frame and vibrating portion together across the through-slot. A package base has two external electrodes. A third frame region has first and second plane surfaces. The protrusion projects toward the vibrating portion and has first and/or second sloped surfaces. First and second extraction electrodes extend from respective excitation electrodes via respective joining portions to respective external electrodes. The extraction electrodes pass across the first plane surface and first sloped surface or across the second plane surface and second slanted surface.

摘要： Piezoelectric vibrating devices have piezoelectric vibrating pieces of which the vibration frequency is measurable individually on a wafer scale, without being affected by adjacent piezoelectric devices on the wafer. An exemplary piezoelectric device includes a piezoelectric vibrating piece having excitation electrodes and respective extraction electrodes. The device includes a package base with two connecting electrodes facing the vibrating piece and connected to respective extraction electrodes. Two pairs of mounting terminals are situated on the outer surface of the package base. Also on the outer surface of the package base are two pairs of opposing castellations that are recessed toward the center of the package base. Edge-surface electrodes connect the first and second main surfaces of the base; one pair is connected to the connecting electrodes and the other pair is connected to respective mounting terminals.
