  • Patent number: 11957052
    Abstract: According to one embodiment, a thermoelectric material are provided. The thermoelectric material includes a sintered body formed of p-type and n-type thermoelectric materials for the thermoelectric conversion element. The thermoelectric materials have a MgAgAs type crystal structure as a main phase. An area ratio of internal defects of the thermoelectric materials for one thermoelectric conversion element is 10% or less in terms of a total area ratio of defective portions in a scanning surface according to ultrasonic flaw detection in a thickness direction of the thermoelectric material. No defect having a length of 800 ?m or more is present at any vertex of chips of the thermoelectric materials.

  • Publication number: 20210032454
    Abstract: A resin composition including a resin having an alcoholic hydroxy group and/or a carboxy group as a crosslinkable group, which exhibits excellent crosslinking reactivity to a polycarbodiimide compound and a polyoxazoline compound even at a low reaction temperature where the resin does not cause discoloration or thermal decomposition; a resin material including the resin composition; and a resin crosslinked body that is a reaction product of the resin composition are provided. The resin composition includes at least one resin (A) containing at least an alcoholic hydroxy group and a carboxy group; at least one crosslinking agent (B) selected from a polycarbodiimide compound and a polyoxazoline compound; and a specific organometallic compound (C). The resin material including the resin composition and the resin crosslinked body are provided.

  • Patent number: 6226263
    Abstract: In an ATM network, a data base is provided in a network controller for holding data pertaining to network topology and remaining network resource. The controller has a supervisory circuit that constantly monitors communication links between ATM switches. Route decision and resource reservation logic circuitry updates the data base if a network fault condition is detected by the supervisory circuit also. The logic circuitry receives, from a source terminal, a reservation request indicating a reservation of an end-to-end network resource between a scheduled start time and a scheduled end time, and makes a search through the data base to reserve the network resource in the data base if the network resource is available.
