Abstract: A method for manufacturing an electrolytic capacitor including: forming a capacitor element having an anode foil and a cathode foil; impregnating the capacitor element with a dispersion solution containing particles of an electrically conductive solid or aggregates thereof and a dispersion solvent to form an electrically conductive solid layer having the particles of the electrically conductive solid or the aggregates thereof in the capacitor element ; and impregnating the capacitor element having the electrically conductive solid layer with a solvent containing no supporting salt.

Abstract: A solid electrolytic capacitor according to the present invention has: a capacitor element (30) having an anode terminal (31) protruding; a resin sheath (6) that covers the capacitor element (30); an anode lead frame (1) having an anode-side terminal surface (10) that is connected to a tip section of the anode terminal (31) of the capacitor element (30) and exposed from the resin sheath (6); and a cathode lead frame (2). The anode lead frame (1) includes, in a portion thereof embedded in the resin sheath (6), a spaced frame section (13) that extends along the anode terminal (31) at a distance from the anode terminal (31) and a bonding frame section (11) that protrudes from a center portion of the spaced frame section (13) to the anode terminal (31) and is bonded to the anode terminal (31).

Abstract: A magnetic head has a pair of magnetic core halves opposed to each other with a non-magnetic material posed therebetween to form a magnetic gap, which head includes a pair of magnetic core halves, a first ferromagnetic metal thin film and a second ferromagnetic metal thin film. The magnetic core halves are formed of ferromagnetic oxide such as Mn-Zn ferrite, and they have opposing surfaces opposed to each other to provide the magnetic gap. The first ferromagnetic metal thin film formed of Fe-Si-Al alloy is formed at least on one of the opposing surfaces. The second ferromagnetic metal thin film formed of Fe-Si-Al alloy having different constituent ratio from the first ferromagnetic metal thin film is formed between the magnetic gap and the first ferromagnetic metal thin film. The flux density of the second ferromagnetic metal thin film induced when a magnetic field of 1.2K oersted is applied exceeds 1000 gauss.

Abstract: A magnetic recording apparatus of a helical scanning system comprises a rotary cylinder (13), recording heads (A and B) and an erase head (10) attached to slightly project from a rotating surface (13a) of the cylinder (13). The rotary erase head (10) has a gap (4) comprising a ferrite core half (1) and a Sendust film (3) formed on a ferrite core half (2) opposed to the ferrite core half (1) and having a larger saturation magnetic flux density. In addition, the recording heads (A and B) and the rotary erase head (10) are attached on the rotary cylinder (13) so that an end (P1) located forward with respect to the tape travelling direction (11) of the Sendust film (3) may trace the backward side with respect to the tape travelling direction (11), apart by a distance which is a half of the gap length of the rotary erase head (10), as compared with a forward end (Q) of a recorded track pattern ( 15a) formed on a tape (14) by the recording head (A) scanning immediately after erasing by the rotary erase head (10).
