摘要： The head-protecting airbag device (M1) includes an airbag (12) provided with a gas admissive portion (13) and a non-admissive portion (23). The gas admissive portion (13) includes a gas feed passage (14) for feeding inflation gas G toward both front and rearwards of the vehicle, and a plurality of vertical chambers (17) juxtaposed along front-rear direction of the vehicle. Each of the vertical chambers (17) includes a communication port at its upper end for communicating with the gas feed passage (14). The substantial lengths of a vehicle's outer wall (13b) and an inner wall (13a) of the airbag (12) are differentiated from each other by a belt (31) in the periphery (19) of the communication port (18). Thus the periphery (19) of the communication port (18) guides inflation gas (G) obliquely down and toward the vehicle's exterior (O) when inflation gas (G) flows into the vertical chamber (17) via the communication port. The head-protecting airbag device (M1) is made compact and improves workability in the mounting work on the vehicle while ensuring downward deployment of the airbag (12) along the window (W).

摘要： To reduce damaging of an inner tube in the vicinity of a gas ejection port of an inflator. To the peripheral portion near an end on a gas ejection port side of an inflator, one end of a pipe is fixed. The pipe extends in the axial direction of an inner tube having such flexibility as a cloth, is smaller in the diameter, shorter and higher in rigidity than the inner tube. In the pipe, its leading end is thinner than a part that is an outer portion of the gas ejection port of the inflator. Further, at the peripheral portion of the end of the pipe, a rear-leading end of the inner tube is clamped by a clamp.

摘要： A multi-layered information recording medium used in an information recording/reproducing apparatus applicable to both a single-layer information recording medium and an arbitrary multi-layered information recording medium is provided. The multi-layered information recording medium has a plurality of recording layers, and each of the recording layers has a guiding groove formed at a track pitch defined as a quadratic function of disk thickness (i.e., the distance from the light incident surface) of the associated recording layer. The guiding grooves of the recording layers are formed such that the track pitch of a reference recording layer having a disk thickness closest to that of the single-layer information recording medium is the smallest amongst the multiple recording layers.
