摘要： PROBLEM TO BE SOLVED: To provide a measurement method whereby a resonant frequency can be measured sufficiently correctly and efficiently under a condition close to a final product with error factors and operation inconvenience in the prior art measurement method eliminated.
SOLUTION: A quartz oscillator 1 of a rectangular plate having a plurality of lead electrodes for excitation electrodes disposed in the vicinity of at least one short side is an object to be measured according to this method. A pair of contact elements 2 are provided which touch thereby holding a small area of a predetermined position of the vicinity of the short side in a perpendicular direction to a plate face. A conductor to be in touch with the lead electrode 12 is set at the contact element. A jig to which a measurement terminal of an oscillator characteristic-measuring circuit 3 according to a transmission method is connected beforehand is used for the conductor. While the quartz oscillator to be measured is held by the contact elements 2, a resonant frequency of the quartz oscillator to be measured is measured by the transmission method.

摘要： PROBLEM TO BE SOLVED: To provide a crystal vibrator which has satisfactory CI value, Q value, etc., and also has more superior overall quality characteristics by improving a conventional technical weak points as those where an electrode film is apt to be eroded by solder and easily broken by impacts, etc. SOLUTION: Supporting region 1a of a rectangular plate type crystal vibration piece 1 includes an electrode 11, which is led out to a short side 17 set toward one of both long sides of the piece 1 from a part of an exciting electrode 10, a fixing electrode 14 which is placed near a corner 19 of the region 1a opposite to the electrode 11 and fixed to the conductor of a container with its expanded region, and a contact electrode 15 which connects the electrodes 11 and 14 together. Then the electrode 15 has a shape having a bending part 15a, where at least the center side edge of the piece 1 forms a concave shape with regard to the side 17. Furthermore, a connecting method is applied to intensively heat a part near the electrode 14 in particular, when the electrode 15 is connected to a support conductor.

摘要： PROBLEM TO BE SOLVED: To greatly improve the uniformization of the thickness of the films formed by vapor deposition, etc., by forming the shape of a film thickness correction plate fixed in the middle between a vapor deposition source and materials for vapor deposition to a triangular shape bulging at the hypotenuse and directing its vertex toward the central axis of revolution motion. SOLUTION: The silver evaporation source 61 to be heated is disposed on the bottom in a bell-jar having a bell-jar inside wall surface 1 and works (materials for vapor deposition) 4 mounted at 10 pieces of work holders 3 rotating horizontally around a perpendicular revolving shaft 2 are disposed in the upper part. The holders 3 are held at the front end of rotating shafts 5 having an angle of 45 deg. with the revolving shaft 2 and revolve around the revolving shaft 2 while rotating around the rotating shafts. The shape of the sheet-like film thickness correction plate 12 fixed to the middle between the silver evaporation source 61 and the works 4 is formed to the isosceles triangular shape bulging at the hypotenuse as shown by a broken line and the vertex of this triangular shape is directed toward the revolving shaft 2. As a result, the change in the particle beam density of the materials to be deposited by evaporation in the range where the resolving loci of the works 4 intersect with the film thickness correction plate is well corrected.

摘要： PROBLEM TO BE SOLVED: To prevent an adhesive agent for fixing a plug and a piezo-electric element piece from adhering to the surface of the piezo-electric element piece or an electrode retained by the piezo-electric element piece by being scattered upon fixing. SOLUTION: The piezo-electric element and the electrode retained by the piezo-electric element are fixed to the plug by forming a resist film on the surface except a bonding surface fixed to the plug and fixing the same to the plug employing solder or conductive paste. Thereafter, the resist film is removed employing resist film separating liquid.

摘要： PROBLEM TO BE SOLVED: To prevent an adhesive for fixing a plug and a piezoelectric element pieces from becoming wet and spread outwardly from a bonding surface to improve a quality. SOLUTION: A piezoelectric element piece used for this application has a water-repellent treated film formed by a spray or dipping method using a fluoride paint, or formed by a reduced or atmospheric pressure plasma processing method using a gas containing fluorine or fluorine compound so as to surround an adhesive surface fixed to a plug. The piezoelectric element piece is fixed to the plug with a solder or conductive paste as an adhesive, the plug is capped with a case, thus forming a piezoelectric vibrator.
