In a component replenishment management system, a component supply monitoring unit estimates replenishable time, which represents time until component replenishment work becomes possible, for each of component supply devices. A work determination unit determines whether or not the component replenishment work can be actually performed at a timing at which replenishment component type information is acquired by an external input and output unit. In a case where the work determination unit determines that the component replenishment work cannot be performed, a work guidance unit generates performing process guidance information. The performing process guidance information is information for guiding a performing process based on the replenishable time of the component replenishment work.

Some embodiments of the inventive subject matter are directed to forming, on a first circuit board, first pins that connect to first leads of a first electronic component; forming, on the first circuit board, second pins that connect to second leads of a second electronic component; affixing the first circuit board to a second circuit board having a first layer with first wires; and forming second wires on a second layer of the second circuit board, wherein said forming the second wires creates an electrical connection on the second circuit board between a portion of the first pins and a portion of the second pins. In some embodiments, the second circuit board is smaller than the first circuit board, and the second layer of the second circuit board is, in length, approximately equivalent to a distance between the first electronic component and the second electronic component.

An axle boring assembly includes a portable power head or drive unit, a bearing pack to which the drive unit is attached, an adjusting base to which the bearing pack is adjustably secured and a mounting assembly which fits over a motor vehicle axle and to which the adjusting base is secured. The mounting assembly comprises a first section having axially spaced apart front and rear clamps and a substantially identical second section with matching spaced apart front and rear clamps. Threaded fasteners extend between the front and rear clamps and may be rotated to secure the mounting assembly about the end of the axle. Each clamp includes jaws which contact the axle and which may be selected from sets of various sizes and configurations to ensure accurate and suitable engagement of the axle.
