摘要： A tape tension control apparatus is applied to a tape winding apparatus for winding a magnetic tape into a tape cassette. In this apparatus, a tampered slot is formed on the back of a vacuum chamber, and the change of the tape position when the magnetic tape is wound into the tape cassette is detected as a change of pressure resulting from a change of the effective width of the slit. Therefore, a constant tape tension can be maintained during the winding process.

摘要： A pump using a piezoelectric diaphragm is designed to allow the diaphragm to be supported appropriately and accurately and to facilitate assembly of housing members. The peripheral edge of a sheet metal of a unimorph diaphragm 40 on the side thereof facing a first housing member 14 is pressed and supported with the ridge of an annular projection 52 annularly provided along the peripheral edge of a vent chamber 38. The first to third housing members 14, 16 and 30 are stacked on one another, and the first and third housing members 14 and 30 are welded together by ultrasonic welding such that the first and second housing members 14 and 16 abut against each other at abutting portions 66 and 68 and the second and third housing members 16 and 30 abut against each other at abutting portions 70 and 72, thereby definitely determining the positional relationship between the housing members.
