Abstract: A woven fabric for airbags has a high quality that can suppress generation of creases during refining, heat setting, and coating steps to be performed after weaving, has an excellent uniform applicability, and can suppress misalignment during cutting. A woven fabric for airbags consists of synthetic fibers, wherein a ratio of a selvedge flare amount R represented by equation (1) is 5.0% or less S=?k=1n(Wk×Hk)/2 R=S/(200×F)×100??(1) wherein, S=selvedge flare amount, in cm2, Wk=selvedge flare width, in cm, Hk=selvedge flare depth, in cm, n is the number of selvedge flares, R is a ratio of a selvedge flare amount, in %, and F is a base fabric width, in cm.

Abstract: A wireless communication unit and a wireless network system enable a plurality of wireless communication units to be wirelessly cooperated with a simple structure, can easily realize cooperative operations, and can execute IP packet transfer control without acquiring communication path information from an external network. A relay wireless communication portion that is connectable to an upstream unit (upstream wireless base station portion) that is another upstream wireless communication unit via an upstream inter-unit wireless bearer is provided. A wireless base station portion is connectable to a downstream unit (downstream relay wireless communication portion) that is another downstream wireless communication unit via a downstream inter-unit wireless bearer.

Abstract: A base fabric for an airbag is formed of a polyamide fiber, wherein a CV value of a weaving density for every 20 cm in a base fabric weft direction is equal to or less than 0.5%, and original-yarn strength usage rates in the warp direction and the weft direction are equal to or more than 85%.
