An airbag gas generator with a simple construction, which operates to apply as small an impact as possible to the passenger during the initial stage of its operation and thereafter rapidly increase the gas pressure to reliably protect the passenger. The airbag gas generator which includes in the housing with gas discharge ports a single ignition means activated by impacts, a gas generating agent ignited and burned by the ignition means to produce a combustion gas, and a filter means to cool the combustion gas and/or arrest combustion residue. The operation performance of the gas generator is adjusted such that the tank pressure measured at 0.25×T milliseconds will be 0.25×P (kPa) or less where a desired tank maximum pressure in the tank combustion test is P (kPa) and a period of time from the start of rising of the tank pressure to the time when the maximum pressure P (kPa) is reached is T milliseconds.

Application No. 06082886; entitled "Stoke for Differential Pressure Casting" Applicant Hitachi Metals Ltd; Inventor--Onishi Sanetsugu. ially cylindrical arrangement, which is adapted for radial expansion and compression; a thick-walled casing comprising rubber, the thick-walled casing being positioned over the plurality of metal segments, thereby forming the drum periphery; the thick-walled casing comprising a plurality of voids arranged on an outer periphery of the thick-walled casing; and an evacuating pump coupled to the plurality of voids, wherein the plurality of voids suction the green carcass onto the drum periphery during compression of the drum periphery; the plurality of voids comprising circular gullies coupled to a network of axially arranged grooves arranged to provide a wave-free and smooth contraction of the green carcass during its compression, thereby avoiding bulges and creases in the contracting green carcass, wherein each of the circular gullies and the network of axially arranged grooves are in communication with the evacuating pump to create a vacuum in both the gullies and the network of grooves. 15. An expandable drum for constructing a green carcass of a tire, the drum having a periphery and comprising: a plurality of metal segments positioned to form a substantially cylindrical arrangement, which is adapted for radial expansion and compression; a thick-walled elastically expandable casing, the thick-walled elastically expandable casing being positioned over the plurality of metal segments, thereby forming the drum periphery; the thick-walled elastically expandable casing comprising a first plurality of voids arranged on an outer periphery of the thick-walled casing; an evacuating pump coupled to the first plurality of voids, wherein the first plurality of voids suction the green carcass onto the drum periphery during compression of the drum periphery; the first plurality of voids comprising circular gullies coupled to a network of axially arranged grooves arranged to provide a wave-free and smooth contraction of the green carcass during its compression, thereby avoiding bulges and creases in the contracting green carcass; and a second plurality of voids located on one of an inner surface of the thick-walled elastically expandable casing and an outer surface of the plurality of metal segments, wherein each of the circular gullies and the network of axially arranged grooves are in communication with the evacuating pump to create a vacuum in both the gullies and the network of grooves.
