Friction lap welding (FLW) is a new conception of joining method developed in Joining and Welding Research Institute (JWRI). The efficiency of joining metal and plastic using FLW was demonstrated through a case study on aluminium alloy AA6061 and MC Nylon-6. The lap joints with high shear strength were obtained over a wide range of welding parameters. A linear relationship was observed between FLW parameters (R/ν)0.5 and the thickness of melted nylon (H). The influences of FLW parameters on bubbles and shear strength were investigated. The morphologies of the fractured surfaces of AA6061 alloy fell into seven types based on the scanning electron microscopy examination. Statistical analysis showed that the contribution to shear strength of these regions followed such an order: region II > region V > region VI > region VII > region IV > region I or III. © 2013 Elsevier Ltd.

Inside a stick base, a variable resistor and a magnet brake are attached to a turnable first bridge. An A/D converter adapted to convert an analog value corresponding to a turning angle, which is obtained from the variable resistor, to a digital value, and a controller adapted to drive the magnet brake when a signal from the A/D converter is given and coincides with a predetermined value are provided. On the basis of data retained in a memory, current is applied to a coil of the magnet brake. Doing so makes it possible to electrically change operational feeling when turning a stick.

A magneto-rheological fluid includes: a magnetic particle mixture; and a dispersion medium in which the magnetic particle mixture is dispersed. The magnetic particle mixture includes first magnetic particles and second magnetic particles. The first magnetic particles have an average particle size greater than or equal to 1 m and less than or equal to 50 m. The second magnetic particles have an average particle size greater than or equal to 20 nm and less than or equal to 200 nm, and have surfaces provided with a surface modified layer. A proportion of the second magnetic particles in the magnetic particle mixture is greater than or equal to 2 wt % and less than or equal to 10 wt %.
