A nonwoven fabric web having an excellent sound absorption coefficient in a frequency range from 800 Hz to 1000 Hz when used as a sound absorbing member for a vehicle exterior. The nonwoven fabric web including a nonwoven fabric having meltblown fibers and binder fibers arranged so as to be confounded with the meltblown fibers and fused with the meltblown fibers at some of the confounding points at the very least, the weight per unit area of the nonwoven fabric being from 400 g/mto 1500 g/m, and the flexural rigidity of the nonwoven fabric being from 2.0 N/50 mm to 20.0 N/50 mm.

Nonwoven fabric web

An adhesive/sealant which is curable by radiation exposure composition having at least one of adhesive and sealant properties and comprising a radiation polymerizable vinyl material, a polymerization initiator for radiation polymerization of the vinyl material, a thermosetting epoxy-containing material and a heat-activatable hardener for the epoxy-containing material.

Adhesive/sealant composition and bonded structure using the same

A control method of the invention is formed with the steps of when a margin angle .gamma. reaches a given minimum margin angle .gamma.min during the operation of a rectifier and inverter, a shunt reactor is disconnected from, or a shunt capacitor is connected to, an AC line of the inverter, and when the margin angle .gamma. exceeds the minimum margin angle .gamma.min by a predetermined value, the shunt reactor is connected to, or the shunt capacitor is disconnected from, the AC line.
