  • Patent number: 10883163
    Abstract: A high-silicon steel strip is manufactured. A basic configuration includes partition plates arranged in the longitudinal direction of a furnace to extend from a position in the vicinity of respective gas nozzles to be in parallel to the pass line of the steel strip, and obstacles arranged to face partition-plate rear edges in the longitudinal direction of the furnace to obstruct the flow of the gas along the steel strip so that siliconizing spaces surrounded by the steel strip, the partition plates, and the obstacles are formed; and gaps between the partition-plate rear edges and the obstacles and so forth which form exhaust passages through which gas is discharged from the siliconizing spaces to other spaces inside the furnace so that treatment gas which has been sprayed from the gas nozzles onto a surface of the steel strip to flow through the siliconizing spaces is discharged through the exhaust passages.

  • Patent number: 10721093
    Abstract: According to one embodiment, an adapter apparatus includes a first connector conforming to the first standard, a second connector conforming to the second standard, a first transmitter and circuitry. The first transmitter transmits a first signal to a first external apparatus connected via the first connector. The first signal associates with a request to determine whether a first mode is supported by the first external apparatus. The first mode corresponds to a communication mode that conforms to a second standard via the first connector. The circuitry generates a second signal when the first external apparatus does not support the first mode. The second signal is used to make an indication representing that the first external apparatus does not support the first mode.
