  • Patent number: 11956314
    Abstract: A network of a new configuration is flexibly constructed while maintaining a stable operation in the network. A management device includes: a detection unit that detects addition of a function unit to a network including one or a plurality of on-vehicle function units; an acquisition unit that acquires function unit information of a new function unit that is the function unit the addition of which has been detected by the detection unit and function unit information of each on-vehicle function unit, each piece of function unit information including information regarding network configuration of a layer lower than an application layer; and a generation unit that, based on the pieces of function unit information acquired by the acquisition unit, generates configuration information of a new network that is the network further including the new function unit.

  • Patent number: 10047483
    Abstract: Provided is a glass interleaving paper capable of suppressing scratches on surfaces of glass plates in a manufacturing process or a distribution process for storing and transporting a plurality of stacked glass plates. The glass interleaving paper is characterized in that a main component is cellulose pulp, a basis weight is 10 to 100 g/m2, and content of mineral having a Mohs hardness of at least 5 is 400 ppm or less. When the mineral having a Mohs hardness of at least 5 is a silicate mineral, the glass interleaving paper is more useful.

  • Patent number: 5270392
    Abstract: The present invention is to improve a thermosetting composition which contains a polymer having a half-esterified acid anhydride group, thus enhancing water and weather resistance. The thermosetting resin composition comprises(I) a compound having an epoxy group and a hydroxy group, and(II) a copolymer prepared from a radically polymerizable monomer having an acid anhydride group and a copolymerizable monomer, of which said acid anhydride group is substantially completely half-esterified.

  • Patent number: 4730010
    Abstract: A cationic water-dispersible resin having quarternary ammonium groups is produced by reacting an acid-addition salt of a polymeric tertiary amine derived from a partially epoxidized polybutadiene-based polymer with an aliphatic secondary amine. The cationic water-dispersible resin is useful for preparing pigment paste and coating compositions to be used in cathodic electrodeposition coating systems.
