摘要:
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.

A negative electrode active material for an electric device includes an alloy containing Si in a range of greater than or equal to 27% by mass and less than 100% by mass, Sn in a range of greater than 0% by mass and less than or equal to 73% by mass, V in a range of greater than 0% by mass and less than or equal to 73% by mass, and inevitable impurities as a residue. The negative electrode active material can be obtained with, for example, a multi DC magnetron sputtering apparatus by use of Si, Sn, and V as targets.

摘要:
An airbag device for the body instantaneously activates an airbag without malfunctions.When an absolute value of an angular velocity detected by an angular velocity sensor exceeds a predetermined angular velocity value, angular velocity values are integrated from a most recent detected value to an oldest value within a predetermined time period, and if an absolute value of a resultant value of integral exceeds a predetermined value and an acceleration detected by an acceleration sensor is smaller than a predetermined acceleration, the airbag is inflated. Based on the value of the integral of the angular velocities, a case in which an angular velocity gradually increases is distinguished from a case in which an angular velocity momentarily increases, so the airbag device effectively prevents malfunctions caused by an action other than falling over. Additionally, because it is unnecessary to intentionally delay determination to prevent malfunctions, the airbag can instantaneously be inflated.

摘要:
A plurality of directional patterns are classified into groups and stored in a directional pattern memory, such that among the plurality of directional patterns, the directional patterns strongly correlated with each other are classified into the same group, while the directional patterns weakly correlated with each other are classified into the different groups. One directional pattern is selected from each group in the directional pattern memory. One directional pattern is determined from the selected directional patterns, in accordance with a communication quality of signals each received when each one of the selected directional patterns is set for steerable antenna element. The determined directional pattern is set for the steerable antenna element.
