Abstract: A bearing assembly is disclosed. The bearing assembly includes a first race. Further, the bearing assembly includes a second race disposed concentric to the first race, where the second race has a radius that changes along an axial length of the bearing assembly. The bearing assembly also includes a housing disposed around the second race and operatively coupled to the second race. Moreover, the bearing assembly includes a plurality of support structures configured to detachably couple the second race to the housing, where the plurality of support structures are configured to disengage the second race from the housing to allow motion of the second race when a torque on the second race is greater than a threshold torque value.

Abstract: The present disclosure relates to methods for manufacturing porous mesh plates for use in ultrasonic mesh nebulizers, and the porous mesh plates manufactured by those methods. Cone-shaped dimples are first drilled in a substrate (e.g. a plate), but do not penetrate the bottom of the substrate. Next, the substrate (e.g. a plate) is subject to an electrochemical process to remove a layer of material from the surface of the substrate. Enough material is removed to allow the dimples to penetrate the substrate, thereby creating holes in the substrate. The size of the holes can be controlled by the conditions of the electrochemical process.

Abstract: Methods of recycling excess semiconductor material removed from an unshaped semiconductor boule are disclosed. Excess semiconductor material is cut from an semiconductor unshaped boule thereby generating a shaped semiconductor boule. The excess semiconductor material is removed in the form of large pieces that can easily be cleaned and retrieved for reuse.

Abstract: A multi-wire electron discharge machine includes a first wire electrode for creating an electrical discharge between the first electrode wire and a semiconductor ingot, a second wire electrode for creating an electrical discharge between the second electrode wire and the semiconductor ingot, and a wire guide for maintaining the first wire electrode in a spaced apart and generally parallel orientation with respect to the second wire electrode across a semiconductor ingot slicing area.
