  • Publication number: 20240047099
    Abstract: It is aimed to provide a wiring harness, in which a part where a wire conductor is exposed from an insulation coating is covered by a waterproof portion and which can maintain the adhesiveness of the waterproof portion to the insulation coating containing a plasticizer even if being placed in a high-temperature and high-humidity environment. A wiring harness is provided with a wire including a conductor, an insulation coating covering an outer periphery of the conductor and a conductor exposed portion, in which the conductor is exposed from the insulation coating, and a waterproof portion for integrally covering surfaces of the conductor exposed portion and the insulation coating. The insulation coating contains a plasticizer. The waterproof portion is constituted as a cured body of a resin composition containing a urethane (meth)acrylate oligomer and a nitrogen-containing monomer, which is a radical polymerizable monomer containing a nitrogen atom.

  • Patent number: 10209926
    Abstract: When the storage system according to the present invention receives a request for writing new data to a first logical volume after having received a first pair creating request, the storage system stores the new data in a cache memory. Then when the storage system subsequently receives a second pair creating request, even if the cache memory still has stored therein the data identical to the data that was stored on the first logical volume at the point in time when the storage system received the first pair formation request, and even if this identical data has not yet been copied to the second logical volume, the storage system omits to copy this identical data to the second logical volume.

  • Patent number: 10102840
    Abstract: If a thickness of a sound absorber arranged in a vehicle and clearances in the vehicle do not match and gaps are formed between the sound absorber and the respective members in the vehicle, abnormal noise due to the mutual contact of the members and noise outside the vehicle enter the vehicle interior to impair vehicle interior quietness. This is solved by a sound absorber which includes a nonwoven fabric containing 5 to 50 mass % of second fibers having a lower melting point than that of first fibers and can cause the first and second fibers to be more loosely interfaced and increase a volume of the nonwoven fabric by heating the nonwoven fabric to about the melting point of the second fibers and softening or melting the second fibers even after production.
