Title: Piezoelectric tuning fork type resonance component
Inventor: INOUE JIRO
IPC: H03H9/02
Filed: 1993-02-22
Abstract: PURPOSE:To prevent obstacle of tuning fork vibration by forming a terminal electrode at a part excepting a gap between the piezoelectric tuning fork type resonator and a substrate. CONSTITUTION:An end surface part at both ends of a gap A is notched to form grooves 15a, 16a. The grooves 15a, 16a are formed by setting grooves by a cut working machine after terminal electrodes 15, 16 being thin film electrodes are formed. When a solder part is formed on the electrodes 15, 16, no solder part is formed on the part of the grooves 15a, 15b, 16a, 16b and no solder part is formed in the vicinity of the gap A. Then the gap A is not sealed by the solder part but opened and when a product is mounted, even when the solder parts 17, 18 are molten, the molten solder does not flow into the gap A. Then the obstacle of tuning fork vibration due to flowing-in of solder part is eliminated when the piezoelectric tuning fork type resonance component is mounted while the inside of the gap A is not sealed at a low pressure.

Abstract: PURPOSE: To efficiently execute mixing and separating of two streams by directing the one stream to the drive ports of respective jet pumps of a cascade and directing the other stream to the suction ports of the same. CONSTITUTION: When the one stream is an org. phase and the other stream is an aq. phase at the time of solvent extraction, the org. phase is admitted into the drive port of the first jet pump 5 by a pump 9 at the inlet to the cascade.
