IPC: B60R21/16
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To provide an air bag having a cut-off function and a dual stage expanding function, and saving a cost by simplifying a circuit structure. SOLUTION: Though an ignition current is energized to an ignition circuit 15 of a first step after judging the operation of an air bag, if a resistance value Rx of the ignition circuit 15 of the first step including a first ignition squib 24, a dummy resistance 25, and a cut-off switch 23 does not exceed a prescribed value, the ignition current is prohibited to be energized to a second step ignition squib 33.

Abstract: PURPOSE:To eliminate the need for after-treatment such as machining, etc., by forming by forging the valve head surface of an engine valve in a recessed shape in advance and subsequently, performing cladding by welding thereon and making the valve head surface almost flat by thermal deformation accompanied by cladding by welding. CONSTITUTION:A cladding by welding part is formed on a face part 4 of the engine valve by performing cladding by welding with powder cladding by welding material by plasma welding, laser beam welding or TIG welding and a valve head part is made almost flat. The thermally deformed quantity A of the valve head surface formed by conventional inert gas shielded powder welding depends on parameters of the valve size, valve material, cladding by welding material, welding conditions, etc. Since the above-mentioned deformed quantity by cladding by welding can be known in advance, a recessed part is formed in a shape to offset almost said thermally deformed quantity and the height B of the truncated cone is set almost equally to the deformed quantity A and an angle C is approximated to the above-mentioned thermal deformation. By this method, when cladding by welding is performed on the truncated conical recessed part, the almost flat valve head surface 9 is obtained as a result of the thermal deformation by welding and the need for after-treatment of machining is eliminated and the full automation can be performed.
