What are the Six Key Design Factors Critical to the Semiconductor Market? Purity and reliability are paramount within the semiconductor and industries. While few product suppliers can meet the stringent requirements of this rapidly changing environment, Servometer® and its sister company BellowsTech, LLC have developed superior engineered electrodeposited and edge welded metal bellows to meet the demanding performance specifications for these applications. This paper describes in-depth, the six key bellows design factors critical to the semi and UHV market.

New Planetary Gearhead Achieves Record Levels MICROMO launches the new FAULHABER 20/1R planetary gearhead, offering the most powerful transmission technology in its class. A 20-mm diameter allows the stainless steel gearhead to achieve continuous torque of 800 mNm, and up to 1,100 mNm in intermittent use. The input speed reaches 12,000 rpm. The 20/1R gearhead can be combined with small brush DC, brushless DC motors, and stepper motors with a diameter of 17 to 22 mm.

Army experiments with providing 'unlimited magazine' to 2025 Soldiers A swarm of experts from across the nation assembled for a two-week experiment recently at Fort Sill in Oklahoma trying out systems with the potential to provide service members with unlimited weapons capabilities. The event, called Maneuver Fires Integrated Experiment, demonstrated two types of weaponry: one using lasers and the other using electricity-propelled projectiles to acquire and destroy targets.

Supersize wind blades are 650 ft long A new design for gigantic blades almost two football fields long could help bring offshore 50-megawatt (MW) wind turbines to the United States and the world. Sandia National Laboratories' research on the extreme-scale Segmented Ultralight Morphing Rotor (SUMR) aims to design a low-cost offshore 50-MW turbine requiring a rotor blade more than 650 ft (200 m) long, two and a half times longer than any existing wind blade.

Honing gives drag racers the winning finish Winning finish has a double meaning for Elite Performance, where the honing expertise of co-owner Nick Ferri has put the "winning finish" into engines behind 57 national NHRA Pro Stock wins and five championships, including back-to-back titles for 2015 Pro Stock Champion Erica Enders-Stevens. Ferri says honing finish rates a "10" in importance for engine seal-up, which translates into higher vacuum, greater fuel pull, and ultimate track performance.

Record-breaking steel metallic glass could be used for body armor, shields for satellites Engineers have created a new material with an unusual chemical structure that makes it incredibly hard and yet elastic. The material can withstand heavy impacts without deforming; even when pushed beyond its elastic limits, it doesn't fracture, instead retaining most of its original strength. That makes it potentially useful in a variety of applications from drill bits to body armor for soldiers to meteor-resistant casings for satellites.

Top Mike Likes: ABCs of gears and more KHK USA takes you on a journey through the history and applications of gears in two information-packed free volumes called "The ABCs of Gears." Part A is aimed at beginners, while part B moves on to intermediate fare, such as types of gears and tooth forms, heat treatment, surface treatment, production methods, etc. Another mid-level text called "Introduction to Gears" and an in-depth "Gear Technical Reference" are also available, chock full of materials information and calculation examples and tables. Best of all, there is no registration for any of these valuable no-cost PDF resources.

Toolbox: Chairless exoskeleton solves long-standing problem The Chairless Chair is a new solution for relieving strain and fatigue from excessive standing during long work shifts. The entire construct is lightweight, easy to put on, and hardly noticeable when walking. By operating a switch on the strap, the flexible construct turns into a stable seat. Two small DC motors activate a stop valve in the hydraulic elements of the shock absorbers, locking the support into the seated position.

| Two-seater electric helicopter takes first flight | |
| Germany-based e-volo's emissions-free Volocopter VC200 took its first official manned flight this month. The all-electric flyer is made of a lightweight, fiber-composite material and features 18 rotors with motors driven by nine batteries. With a 450-kg take-off weight, the VC200 requires about 45 kW to hover, depending on the air pressure/temp. Its built-in multiple redundancies help ensure stability, even if parts of the system fail, and make the unit easy to fly using only a joystick. Unlike a helicopter, the blade angle on the VC200 cannot be adjusted. The amount of thrust produced depends solely on the rotation speed of the rotors. The copter received its permit to fly as an ultralight aircraft from German aviation authorities in February, and NASA invited e-volo to present the technology at its On-Demand Mobility workshop in Washington, DC, this past March. And did we mention it folds up too?
