摘要： PROBLEM TO BE SOLVED: To securely connect a stem and a board of a surface mount piezoelectric transducer in which the stem on one end of a cylindrical piezoelectric transducer with a vibration tab in it is connected to an electrode terminal with caulking, and the stem and the electrode terminal are insert-molded with resin, even if the caulking is not tight enough and hence the electrical connection between the stem and the board is unstable. SOLUTION: This surface mount piezoelectric transducer has a cylindrical piezoelectric transducer which has a vibration tab in it and a stem provided on its one end, and an electrode terminal connected to the stem with caulking. The stem and the electrode terminal is insert-molded. The lower side of the caulked part is not covered with the resin to expose a part of the stem on the lower surface side.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a Pb plating airtight terminal which is excellent in appearance characteristic, etc., by establishing respective factors and conditions at the time of executing high temp. soldering and plating (Pb plating). SOLUTION: After the pretreatment such as the defatting, washing and activation of the airtight terminal is executed in the manufacturing method of the Pb plating airtight terminal by which the Pb plating (90% or larger Pb plating) is executed on the surfaces of an outer peripheral metal and a lead, 1. Ni plating is executed on the airtight terminal as a substrate of the Pb plating. The roughens of a basis material is reduced by setting the thickness of Ni plating to 2 to 5 μm. 2. Next, the surface condition of the Pb plating is improved by removing an oxidized film of the airtight terminal, on which the substrate Ni plating is smoothly executed, thereby activating the surface of the substrate Ni plating. 3. Next, the airtight terminal is immersed into a Pb plating bath, to which a brightening agent is added, to electrodeposit the Pb plating by setting the Pb content in the Pb plating bath to 90 to 92.5%. 4. Finally, the Pb plated airtight terminal is completed by executing the chemical treatment or heat treatment of the Pb plated airtight terminal.

摘要： PURPOSE: To reduce leakage defect by applying solder plating to the surface of the air-tight terminal and forming an oxide film onto the surface of the solder plating. CONSTITUTION: Solder plating is applied 15μm thick to the surface of an air- tight terminal 1 on one side. The air-tight terminal 1 with solder plating is put into a furnace, in which the temperature is increased to apply oxidation processing to the surface of the solder plating. The melting point is increased by applying oxidation processing to the surface of the solder plating to form an oxide film. The oxide film 780Å thick is formed for oxidation processing at 300 deg.C for five hours. The oxidation processing at 300 deg.C for 5 hours is best, but the temperature is changed within the range between 200-300 deg.C and the oxidation processing time is managed in response to the set temperature to obtain the excellent air-tight terminal.

摘要： PROBLEM TO BE SOLVED: To perform a vacuum heat treatment in an appropriate time, though a work gas adsorption quantity and work charging numbers, etc., deviate, by controlling a vacuum heat treatment with the whole gas pressure or a specific gas partial pressure in a vacuum heat treatment furnace. SOLUTION: Pressure in a vacuum heat treatment furnace changes with a balance between gas generating from various gas sources by heating the work from a heating point T1 where the heating is started to a T2 point and evacuation with a RP. In a specified range of work heated temperatures from the work heating temperature T2 to a T3 point, a gas generation from various gas sources gradually lessens and it is judged that a gas evacuation finished at the T3 point. This judgement is based on many numbers of experiments and the reference for judging whether the object vacuum heat treatment is completed or not, is decided with the whole pressure or a specific gas partial pressure of respective gas sources. By watching the gas source affecting the quality of the work after the vacuum heat treatment, the judgment may be decided.
