Title: Manufacture of electrolytic capacitor
Inventor: FUJIMURA HIDEO
IPC: H01G9/028
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a low ESR, large-capacitance capacitor element by immersing the capacitor element, which is impregnated with a monomer serving as a conductive polymer by oxidation polymerization, into a surfactant-added oxidant aqueous solution. SOLUTION: To form a conductive polymer layer within a capacitor element 7 which is formed by winding anodized foil 1 and counterposed cathode foil 2 through a separator 3, first, an appropriate amount of pyrrole monomer is dripped to the element 7. The element 7 is then immersed into an aqueous solution containing an oxidant such as ammonium persulfate and a surfactant such as polyoxyethylene aromatic inducer for 5 minutes, thereby chemically polymerizing the pyrrole monomer rapidly and hence forming the conductive polymer layer. Then, the resulting element 7 is rinsed with water and dried in a drying furnace at about 100 deg.C for about 30 minutes. The monomer can be polymerized rapidly and uniformly, and can also be prevented from flowing outside the element 7, and thus the conductive polymer layer can be formed uniformly within the element 7.  As a result, a large-capacity, low ESR electrolytic capacitor can be obtained.

SOLUTION: The part 13 having the difference in level is provided on the joined position of a head signal line terminal 14 of a slider mounting stage 10 on a flexture 3 so as to form the recessed state confronting with a recording medium, and a wedge shaped space is formed between the wall surface of a tray ring edge 9 of the slider 4 and the inclined surface of the difference in level, then the solder bump 15 is buried therein to press-fix the signal line. The solder bump is thereby fixed to the wedge shaped space, and the bonding workability is increased. Also, the connecting area with the head signal line is extended, then the stable and fine connection is obtained.  Further, the amplitudes of the primary and secondary twist vibration modes are suppressed to be small since the position of a centroid of the slider is approached to a center axis of twist of a load beam, and the fine vibration characteristic is obtained.
