  • Patent number: 5669126
    Abstract: A terminal for a piezoelectric device has a first electrode portion, a second electrode portion folded on the first electrode portion, projections on the first and second electrode portions, and further a vibration absorber between the first and second electrode portions. As the vibration absorber, oil, a non-volatile component of oil, silicone grease, polyamide resin, paper, an anticorrosive, a coating agent, silicone rubber, etc. may be used. Another terminal for a piezoelectric device has a sealant between the first electrode portion and the second electrode portion.
    Type: Grant

  • Patent number: 5481791
    Abstract: A magnetic core provided with one or more concave mark(s) with a depth of 2 um or less on at least one side surface of the magnetic core for a floating-type complex magnetic head, wherein the magnetic gap depth is controlled by machining the air bearing while observing a specific portion, from the direction perpendicular to the air bearing, of a concave mark or observing the level difference of specific portions of multiple concave marks provided on the side surface of the magnetic core in relation to the position of the apex of the magnetic core after cementing the magnetic core using glass filler inside a slit provided in the air bearing of a slider.

  • Patent number: 4220500
    Abstract: A non-woven glass fiber-containing sheet composed of a top layer of a mixture of glass fiber with other fiber and a back layer of a mixture of fiber other than glass fiber with polyvinyl chloride fiber or polyvinyl chloride latex flocculate is a suitable substrate for processing it into flooring, walling, roofing, etc. by impregnating it with a polyvinyl chloride sol to strengthen the sheet without exudation of the sol onto the back layer surface.
