A chip module and a fabricating method thereof are provided. A compressible air stream that contains oxygen is mixed in a substantially co-current flow with an incompressible fluid stream comprising an incompressible fluid in which oxygen is capable of being preferentially absorbed. The rotation portion has an extension extending from a bottom of the sleeve to be received in a through hole defined in the circular wall so that the rotation portion is able to be rotatable relative to the fixed portion. The tunable balancing network is operable to establish an impedance that substantially matches an impedance of the antenna. The compositions are preferably cosmetic preparations. Accordingly, the front-rear-directional collision load is stably transmitted to a member, such as an adjacent engine, such that it is possible to efficiently improve the effect of distributing and reducing the load in a collision.
