Influence of Preexcitation, High Temperature Magnetization and Combined Excitation Method on Screening Current Attenuation in Conduction-Cooled REBCO Coil

Autor: Yoh Nagasaki, Daisuke Miyagi, Jun Miyazaki, Shoichi Yokoyama, Hideaki Miura, Makoto Tsuda, Masatoshi Kanamaru

Publikováno v: IEEE Transactions on Applied Superconductivity. 30:1-6

This article investigated a suitable excitation method for a conduction-cooled REBCO coil to reduce the temporal attenuation of the screening current induced field (screening field) for magnetic resonance imaging. We investigated the effect of the pr

Fabrication of Aspheric Micro-Lens Mold with High Aspect Ratio -Method to Form Small 3D Structures with an Arbitrary Aspheric Surface and High Aspect Ratio

Autor: Takeshi Shimano, Irizo Naniwa, Masaya Horino, Shigeo Nakamura, Masatoshi Kanamaru

Publikováno v: IEEJ Transactions on Sensors and Micromachines. 129:426-429

The optical pickup of our Small-Form-Factor Optical Disc Drives (SFFODDs) requires a micro-objective whose profile is composed of two aspheric surfaces. However, it is difficult to fabricate a micro-objective with an arbitrary aspheric surface and hi

Publikováno v: Journal of Micromechanics and Microengineering. 15:1754-1761

An optical beam scanning array (OBSA) integrating two mirror arrays and a collimator-lens array was fabricated. The passive self-alignment inserting a pin into a through-hole was carried out for integration of the mirror arrays and the collimator-len

Low-Insertion-Loss Optical Matrix Switch Using MEMS Micromirrors Assembled by Passive Alignment

Autor: Atsushi Kazama, Ryoji Okada, Teruhisa Akashi, Tadaaki Ishikawa, Masaya Horino, Takeshi Harada, Yasuhiro Itou, Kazuyuki Fukuda, Masatoshi Kanamaru

Publikováno v: JSME International Journal Series B. 47:501-507

A three-dimensional (3D)-type MEMS optical switch with low insertion loss and low assembly cost has been developed. The switch consists of two optical beam scanners placed facing each other. Each scanner consists of a collimator array and two mirror
