A data processor whose level of operation parallelism is enhanced by composing floating-point inner product execution units to be compatible with single instruction multiple data and thereby enhancing the operation processing capability is made possible. In accordance with the present invention, it is possible to achieve fifty three bits of precision in less processing time than previously possible. The wheel guard has a bight, a first and second tine, each tine having a proximal end structured to be coupled to the bight and distal end structured to be coupled to the wheelbarrow yoke. The locking devices are fixed at opposite side positions above the eyelet lines. Valve metal oxides andor suboxides thereof are also described as well as capacitors containing anodes made from the valve metal oxides and suboxides thereof. Mounting holes for a first and third style bucket with equal pin spacing are provided on the first link.
