NSK’s miniature, large-lead series of ball screws is designed with small shaft diameter (6 and 8 mm), to reduce the load on motors, and the largest lead of its class (8, 10, 12, and 15 mm). The series achieves rotational speeds up to 5000 rpm, enabling smooth operation and equipment requiring a relatively short stroke to operate at speeds exceeding 1 m/s. It also features a low-profile nut that is claimed to be the smallest on the market. The series can replace linear motors and small air cylinders, due to its high-speed, high-precision, multipoint positioning, and is suited for semiconductor chip mounters and parts-aligning equipment.

Researchers from Purdue University are studying the fundamental mechanisms behind a method that uses electrical fields to enhance ceramics-sintering processing, which could aid R&D of rechargeable lithium-ion batteries and fuel cells. The research also could shed light on a phenomenon called electromigration, which can affect the performance of electronic devices.

One of the biggest issues in bringing forward new designs is the length of time that it takes to agree to a new specification, research and evaluate the alternative features and configurations, and then embark on a development program that will take the design to flight testing and ultimately operational service.
