Abstract

PURPOSE:To improve the stability of mass production and to make the vessel for quartz oscillator small-size and low-cost and to improve the performance, by holding a quartz bar between a member having a glass projection and another member. CONSTITUTION:A vessel consists of two members. One member 21 is made of glass and has a projection which should be brought into contact with a crystal 15. The other member 18 is made of ceramic. The crystal 15 is held between both members. The crystal 15 is held by the hard glass to keep the Q value high. The vessel is sealed simultaneously with holding the quartz 15. The vessel is sealed while heating the projection brought into contact with the quartz 15 to absorb the variance of the member and the projection, thus holding the quartz more surely.
