    • A method of producing a grain-oriented electromagnetic steel sheet comprising the step of subjecting a sheet of hot-rolled steel containing silicon less than 4.5% to more than one operation of cold rolling and more than one operation of annealing, so as to set the thickness of said sheet to that of a commercially standard sheet, and also subjecting the sheet to the step of final high-temperature annealing. Prior to said final high-temperature annealing, part of the surface of said sheet is worked for controlling the growth of secondary recrystallization grains by working the sheets such that lines of less than 3.0 mm wide are formed on the surface of the steel sheet spaced apart at intervals of more than 5.0 mm so that the total effect is to produce worked and unworked regions alternatively arranged in lines across the steel sheet. Such working is effected by mechanical plastic working, local thermal treatment and by chemical treatment. The worked regions serve to control the growth of secondary recrystallization.
    • 一种晶粒取向电磁钢板的制造方法,其特征在于,包括以下步骤:将含有小于4.5%的硅的热轧钢板进行多次冷轧和多次退火操作, 所述片材的厚度与市售标准片材的厚度,并且还使片材经受最终高温退火的步骤。 在所述最终的高温退火之前,通过加工片材来对所述片材的一部分表面进行加工,以控制二次再结晶晶粒的生长,使得在钢板表面间隔开形成小于3.0mm宽的线 间隔大于5.0mm,以便总的效果是产生交替排列在钢板上的加工和未加工区域。 这种工作通过机械塑料加工,局部热处理和化学处理来实现。 工作区域用于控制二次再结晶的生长。

    • In the case where one set of EDCA access parameters is set, there are problems such as failure in performing QoS when a transmission rate is changed and a deterioration in transmission efficiency. A relay device is a wireless communication device which transmits received data according to a priority level of the data, including: a transmitting unit which transmits received data; a rate measuring unit which measures a rate at which the transmitting unit transmits the data; and a transmission control unit which adaptively controls a transmission waiting time for which the transmitting unit waits until start of the transmission of the data, according to the transmission rate of the transmitting unit which is measured by the rate measuring unit, wherein the transmitting unit transmits the data according to transmission control by the transmission control unit.
