The method includes providing a shaft made of steel, and pouring a casting alloy around an end of the shaft, wherein the casting alloy includes an intermetallic compound of the system TiAl. The method is particularly well-suited making a connection of the turbine wheel and the shaft of an exhaust-gas turbocharger for motor vehicles using a casting process. In addition, a turbine wheel rotor, that includes a steel shaft, a cast wheel including a casting alloy fixedly connected to an end of the shaft. The casting alloy including an intermetallic compound of the system TiAl. A connection between the cast wheel and the shaft includes at least one of a friction fit, a positive fit, and an integral connection.

A feeder stand including a rotary ground auger and base holds a feeder above the ground. An upright elongated rod defines a stand supported by an auger having helical coils removably screwed into the ground. A platform such as a round disc, or wire mesh platform is supported on the top distal end of the rod. At least two opposing legs extend perpendicular to the vertical elongated rod and auger forming a base. The distal end of selected opposing legs are bent or angled upward perpendicular from the ground forming handles for rotating the auger into the ground. The portion of the legs extending outward normal to the elongated support pole provides a base bearing against the ground for increased lateral support.

A light-emitting device includes a light-emitting element and a light-guiding member for causing light from the light-emitting element entering into it through one surface thereof. The light-emitting element includes a lead member with a light-emitting element chip mounted thereon and a molded member to which the lead member is secured. The lead member has a metallic part extending from the molded member, and the metallic part is bent. The thus arranged light-emitting device has an excellent heat release capability. An image reading apparatus using the light-emitting device is also provided.

Disclosed is a unique concept of a physical training apparatus which applies resistance to a trainee during athletic movements from a set position in the natural environment of the sporting activity to aid in enhancing speed and acceleration. The said physical training apparatus is designed to be used in conjunction with a starting apparatus to allow the trainee to execute resistive movements with identical technique to a sporting activity. The versatility of design of the disclosed invention allows the trainee to better translate the benefits of a resistive exercise into a sporting activity by incorporating the use of common athletic elements. Further benefits stem for the reduction of time and movement between a resistive exercise and an unrestrained athletic routine due to the ability of the disclosed invention to be utilized within the environment of the sporting activity.

A bracket is provided for connecting an airbag module to a structural member in an automotive vehicle. The bracket provides three degrees to freedom to allow the fit and finish of the interior panels to be determined without being affected by the rigid connection between the airbag module and the structural member. Holes are also provided in the bracket for tuning energy management.

A rotary mounting stand for removably holding a decoy, camera or there selected device upright on the ground. The stand includes an upright rod with a helical coil or flights forming an auger having a point at the lower distal end to be fixedly and removably screwed into the ground to support the stand in an upright position. The top end of the rod forming the stand shape cap configured, sized and shaped to correspond to the mounting base of a selected device to be supported on the stand. Just above the helical coil at least two outward extending legs extend normal to or perpendicular to the vertical rod forming a base when the auger portion is screwed into the ground. The distal end of each of the legs are bent or angled to extend upward perpendicular from the ground a selected distance forming handles for the purpose of rotating the auger into the ground. The auger is intended to be cranked until the at least two outward extending legs come to bear against the ground for increased lateral support.
