  • Wiring substrate having metal post offset from conductor pad and method for manufacturing wiring substrate
    Patent number: 11935822
    Abstract: A wiring substrate includes a resin insulating layer, a via conductor formed in the resin insulating layer such that the via conductor is penetrating through the resin insulating layer, a conductor pad formed on the resin insulating layer and connected to the via conductor, a coating insulating layer formed on the resin insulating layer such that the coating insulating layer is covering the conductor pad, and a metal post formed on the conductor pad and protruding from the coating insulating layer. The conductor pad is formed such that a central axis of the conductor pad is shifted in a predetermined direction with respect to a central axis of the via conductor, and the metal post is formed such that a central axis of the metal post is shifted in the predetermined direction with respect to the central axis of the conductor pad.

  • Surface having a coating of a host multidentate ligand and a reversibly trapped lubricant
    Patent number: 5830577
    Abstract: The lubricant layer according to the present invention is used in a thin film magnetic recording medium in which a solid surface sliding at a high speed is required to retain its lubricating performance and abrasion resistance for a long period of time, comprising a host-guest complex composed of a lubricant molecule as a guest molecule and a multidentate ligand as a host compound to form the complex with the guest molecule.

  • Feed for swine and method of breeding swine using the same
    Patent number: 5431928
    Abstract: A feed for swine containing a casein digestion product of which a principal component is casein phosphopeptide, and a method of breeding a swine which comprises feeding a feed for swine containing 0.01 to 1 part by weight of a casein digestion product of which a principal component is casein phosphopeptide per 100 parts by weight of usual feed for swine. By feeding the feed for swine of the invention, the absorption of minerals, such as calcium and iron is promoted in pregnant sows, resulting in the improvement in the blood properties and milk quality. Piglets are slao improved in the blood properties and ossification degree by feeding the feed for swine of the invention.
