  • Publication number: 20100112832
    Abstract: A connector includes a housing and a contact. The contact includes a first part including a first terminal part and a first connection part; a second part including a second terminal part and a second connection part, and a third part including an elastic part having a first end and a second end connected to the first part and the second part, respectively. The first connection part and the second connection part face each other across a gap. The second terminal part is configured to come into press contact with an electrode in response to fixation of the housing to a board. The third part is configured to elastically deform in response to attachment of a plug to the housing and/or the fixation of the housing to the board, so as to cause the first connection part and the second connection part to come into contact and be electrically connected.

  • Patent number: 7686618
    Abstract: A connector has a housing, contact modules accommodated within the housing and having transmission path patterns with ends which form a plurality of contacts, and a connecting surface. Each of the contacts is exposed at the connecting surface. The contacts of each of the contact modules are aligned in a first direction, and corresponding contacts of the contact modules are aligned in a second direction perpendicular to the first direction, so that the contacts are disposed in a matrix arrangement. The lengths of adjacent transmission path patterns are identical within each of the contact modules but different among the contact modules.

  • Patent number: 6798625
    Abstract: The present invention provides a spin-valve magnetoresistance sensor in which are formed, on top of the substrate, free layers, and pinned layers, enclosing a nonmagnetic spacer layer, and an antiferromagnetic layer adjacent to the pinned layers. The sensor is also equipped with a back layer including at least two nonmagnetic metal layers adjacent to the free layers on the side of the free layers opposite the nonmagnetic spacer layer. The back layer has at least one nonmagnetic metal layer of Cu with high electrical conductivity, preferably formed adjacent to the free layers, as for example in a two-layer structure of Cu and Ru or a three-layer structure Ru/Cu/Ru. In addition to a high read output, fluctuations in Hint with the film thickness of the back layer can be suppressed and sensor characteristics stabilized, and high recording densities can be realized.
