专利汇可以提供Process for the manufacture of a piezoelectric suspension device专利检索，专利查询，专利分析的服务。并且Process for the manufacture of a piezoelectric resonator suspension device, this device comprising at least two flexible connections welded on the one hand to two electrodes of the resonator and on the other to at least two supports, the connections serving as connections for the resonator electrodes, and further comprises a comb-piece is cut out from a thin metal plate, having on the one hand positioning devices and on the other at least one flexible connection having a first part forming a stub for welding to one of the electrodes of the said resonator, and a second part forming a spring and whose end is for welding to one of the said supports, there being on the said stub a welding plate for welding the said stub to the said electrode, at least one of these comb-pieces being taken and located, by the said positioning devices, in a jig in which the said resonator is held so that the said stub equipped with its welding plate comes to bear against a predetermined point on the said electrode, the welding plate being fused so as to weld stub and electrode together, the said suspension device being parted from the said comb-piece and the end of the second part of the said device being welded to one of the said supports.，下面是Process for the manufacture of a piezoelectric suspension device专利的具体信息内容。

权利要求

1. A process for the manufacture of a piezozelectric resonator suspension device comprising the steps of: a. forming a comb-piece from a thin metal plate, b. forming positioning means in the thin metal plate for positioning same in a jig, c. forming at least one connection in the comb-piece, said connection having an end part forming a stub and a flexible spring-like portion connecting said connection to the combpiece and a bulge being provided in said flexible spring-like portion in proximity to where said portion joins the combpiece, d. providing a welding plate on said stub, e. positioning said comb-piece by means of said positioning means in said jig and positioning a said resonator in said jig so that said stub equipped with said welding plate comes to bear against a predetermined point on one electrode of the piezoelectric resonator. f. welding said welding plate to said predetermined point on said one electrode, g. parting said flexible spring-like portion from said combpiece between the comb-piece and said bulge, and h. welding said bulge to a support of the suspension device.

2. A process according to claim 1, further comprising the steps of forming two like said connections in the comb-piece so that when said comb-piece and said resonator are positioned in said jig the welding plate of each connection can be welded to thE corresponding one of two electrodes of said resonator, parting the flexible spring-like portion of each said connection from said comb-piece between the comb-piece and the corresponding bulge, and welding each bulge to a discrete support of the suspension device.

3. A process according to claim 2, further comprising forming in said comb-piece a pair of abutments in the form of additional positioning devices, one abutment being situated near the stub of each said connection, and each abutment projecting outwardly from said comb-piece in relation to the outward projection from said comb-piece of the corresponding welding plate such that when said abutments are positioned against the corresponding one of said electrodes each welding plate is urged slightly inwardly towards the comb-piece by flexing of the flexible spring-like portion of the corresponding said connection.

4. A process according to claim 1, further comprising carrying out the steps a) to h) in relation to each of two opposite sides of said one of said electrodes of the resonator so that a pair of said connections are provided to said one of said electrodes and the bulge of each of said connections is welded to a discrete support of the suspension device.

5. A process according to claim 1, in which said comb-piece is formed of gilded beryllium bronze and said stub is welded to said predetermined point on said one electrode by a gold and tin based weld.
