A method of making a rare-earth alloy granulated powder according to the present invention includes the steps of: preparing a rare-earth alloy powder; generating remanent magnetization in the powder; and granulating the powder by utilizing agglomeration force produced by the remanent magnetization of the powder. The telescoping waterway includes a hollow outer tube, a hollow inner tube within the hollow outer tube, and an actuator that moves the hollow inner tube relative to the hollow outer tube, wherein the hollow inner tube can be maintained in at least one intermediate position between a retracted position and a fully extended position. A wire is wound on any of the teeth to form a normal coil. Thus, the electric field is distributed in the intrinsic region of the Ge\u2014Si photodiode where there is low dislocation density. The system can send content to the mobile device based on the mobile device’s location and predicted future locations along the predetermined route. A remaining portion of the pillar frame provides an interconnect pillar and inductor pillars around the inductor core.
