Autor: Tomoya HATTORI, Noboru KAWAGUCHI, Yutaka EZAKI, Junji TAKAKI, Masao SAITO, Masahiro SUGIMOTO, Satoshi SATOH, Katsuhiko YAMADA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 87, Iss 900, Pp 21-00060-21-00060 (2021)

In the control of a large structure, hydraulic equipment is often used because it requires a large output. In this study, we focus on a telescope as an example of a large structure, and experimentally verify the basic characteristics of the hydraulic

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 87, Iss 900, Pp 21-00059-21-00059 (2021)

In the control of a large structure, hydraulic equipment is often used because it requires a large output. In this study, we focus on the telescope as an example of a large structure, and model its hydraulic support system and analyze its characteris

Publikováno v: Observatory Operations: Strategies, Processes, and Systems VIII.

Some of optical telescopes and millimeter- and submillimeter-wave telescopes are constructed on the top of the mountains which are higher than 4,000 meters above sea level, in order to prevent light from absorbing and diffusing and to avoid the influ

Publikováno v: Ground-based and Airborne Telescopes VIII.

The Thirty Meter Telescope (TMT) is expected to reveal the birth of galaxies, planetary surfaces and even the atmospheric composition of exoplanets. The TMT is an optical infrared reflecting telescope that uses very large hydrostatic bearings in the
