Abstract: PURPOSE:To provide the constitution of a crystal resonator with low erroneous recognition and to provide the crystal resonator with stable electrical characteristic and high reliability when the coating state of a joining material is detected by a photoelectric sensor. CONSTITUTION:Supporting bodies 21, 22 provided with slits for crystal plate insertion are spot-welded on a base 1. The supporting bodies 21, 22 are nickel- plated, and the surfaces of them display silver color. The crystal plate 3 on which excitation electrodes 31, 32 are formed is loaded between the supporting bodies 21, 22, and they are joined electrically/mechanically with a conductive joining material. The conductive joining material is formed in paste shape in which an adhesive of epoxy resin system, etc., a solvent, and silver of particulate shape are mixed, and the surface color of the material after hardening displays a color of brown color series. When a joining part is detected by the photoelectric sensor, the presence/absence of the joining material can be surely discriminated since the colors of them are different.

Abstract: PROBLEM TO BE SOLVED: To provide an optical filter with which a light translucent optical plate is easy to distinguish and manufacturing cost can be reduced.
SOLUTION: The optical filter F1 is constituted of a quartz crystal wavelength plate 1, an infrared-absorbing glass plate 2 and a quartz crystal birefringent plate 3, and their main surfaces are stuck with an adhesive. Although it is not illustrated, an antireflection film (AR coated film) is formed on a light-emitting surface (rear surface) of the quartz crystal birefringent plate 3. Furthermore, the quartz crystal birefringent plate 3 has a profile size which differs from that of the quartz crystal wavelength plate 1 and the infrared-absorbing glass plate 2 and has an extension part 31, which extends in longitudinal directions (vertical directions). Additionally, a marking M is formed by laser, at the extension part 31 which is extended upward.

Abstract: PROBLEM TO BE SOLVED: To provide a method for air-tightly sealing a quartz vibration device where the inside of its package is evacuated and a sputtered metal at air-tight sealing hardly enters the inside of the package. SOLUTION: A metallic cover 3 applies seam welding sealing to a ceramic package 1 in which mount of a quartz vibrating plate is completed in an inactive gas atmosphere. First parallel seam welding is applied from one end in a direction of a long side toward the other end as shown in arrows A, A. The seam wielding does not completely weld the long side direction. Then all parts are welded up to the other end in a direction sown in arrows B, B. Gases in the quartz vibrator are eliminated after that, and spot resistance welding is applied to areas C, C not welded in this state to complete the air-tight sealing.
