Rotary stepping device with memory metal actuator [PDF]
, 1987 A rotary stepping device includes a rotatable shaft which is driven by means of a coiled spring clutch which is alternately tightened to grip and rotate the shaft and released to return it to a resting position.

3D‐Printed Giant Magnetoresistive (GMR) Sensors Based on Self Compliant Springs
Advanced Engineering Materials, EarlyView.This work explores 3D‐printed GMR sensors utilizing self‐compliant spring structures and conductive PLA composites. By optimizing arm width, we achieved high piezoresistive (0.34%/mm) and magnetoresistive (0.77%/mT) sensitivities. Demonstrated through Bluetooth‐integrated pressure and magnetic position sensing, these full printed low‐cost, customizable

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures
Advanced Engineering Materials, EarlyView.This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Matsunaga's Automatic Devices for Quenching Spring Plates
Transactions of the Society of Mechanical Engineers, 1935 ばね板の燒入は一般に燒入液として種油を使用した2段操作燒入法(以下從來焼入法と稱す)が採用されてゐるが、この燒入法は以下細説する如く製品の品質統一上に不尠る不便があり且又經濟上に或は作業能率上に於ても改良研究すべき幾多の分野が殘されてゐる。依つて因襲的な從來の燒入法に對し可及的に生産能率を向上せしめ、品質に就ても改良統一を計るため燒入液として古礦油を使用する1段操作燒入法を採用し且燒入燒戻の熱處理を自動的に行ふ松永式ばね板自動燒入装置(以下本燒入法と稱す)を發明した。茲に本燒入装置に就て構造操作及び使用方法等の概略に就て説明した後、兩燒入法に依つて製作したばね板の各材質試驗成績及び彈機に就ての荷重、耐久 ...

Unilateral and Bilateral Virtual Springs: Contact Transitions Unmask Device Dynamics
IEEE Transactions on Haptics, 2019 The study of haptic perception often makes use of haptic rendering to display the variety of impedances needed to run an experiment. Unacknowledged in many cases is the influence of the selected device hardware on what the user will feel, particularly in interactions featuring frequencies above the control bandwidth.

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
