  • Publication number: 20080055788
    Abstract: This invention provides a magnetic head having adjustable input/output impedance, and also provides a manufacturing method of the same, a head suspension assembly and a magnetic storage device. The magnetic head has a perpendicularly feeding type magnetoresistive element, a pair of electrodes, a pair of first conductive wires for electrically connecting the pair of electrodes to a detecting circuit device, a pair of second conductive wires for discharging static electricity by electrically connecting the pair of the first conductive wires and a grounded substrate through bleed resistance, and one or more grounded electrically shielded layers between the first conductive wires and the substrate, and/or between the second conductive wires and the substrate.

  • Publication number: 20080043377
    Abstract: The magnetic head is capable of stabilizing arrangement of magnetic domains in a shield layer of a read-head, preventing variation of characteristics of the read-element and improving reliability. The magnetic head comprises the read-head, in which the read-element is magnetic-shielded by a shield layer. A step-shaped section is formed in a base layer, on which the shield layer is formed, and the step-shaped section corresponds to a border of at least one of domain areas, which are defined by desired magnetic domains to be formed in the shield layer after a magnetizing process.

  • Patent number: 5248531
    Abstract: A hemolysis depressant and a plasticizer each comprising a triglyceride compound. Resin compositions for medical appliances, medical implements and blood preserving liquid using the triglyceride compound as a hemolysis depressant are capable of preventing the blood held in contact therewith from the phenomenon of hemolysis by the activity of the compound in protecting erythrocytes. Vinyl chloride type resin compositions for medical appliances and medical implement using the compound as a plasticizer are substantially deviced of toxicity and offers extremely high safety.
