The DeeMe experiment to search for muon-to-electron conversions with a sensitivity 10–100 times better than those achieved by previous experiments is in preparation at the Japan Proton Accelerator Research Complex. magnetic spectrometer used consists of an electromagnet and four multiwire proportional chambers (MWPCs). newly developed MWPCs are operated high voltage (HV) switching technique hav...

In this paper, we demonstrate 3D-printed 1-DOF (one torsional axis; 1 degree of freedom) optical scanners with large mirror areas (up to 20 × mm2). Each device consists an aluminum-coated square silicon substrate serving as the mirror, two miniature permanent magnets, electromagnet, and a structure including frame, torsion springs, base. One can reach static half scan angle 14.8 deg., i.e., ful...

Braking systems in motor vehicles generally use a braking system that utilizes friction. The performance will decrease caused by using friction rapidly. To overcome this, as an alternative, electromagnetic can be used utilizing eddy currents, such current brakes (ECB). Eddy currents are generated when the rotor pass magnetic field of electromagnet. research aim is to design ECB system. disk det...

This work proposes a new technique for creating active bubbles and droplets with non-magnetic core coating formed by magnetic fluid. The procedure consists of the injection phase into one that is supported presence an inhomogeneous field from source, which combines annular magnet electromagnet. We explored various modes leading to different drops as well influence on size, velocity, acceleratio...
