On-Orbit Robust Control Experiment of Flexible Spacecraft ETS-VI
TL;DR: In this paper, three types of controllers were designed in linear quadratic Gaussian and H 1 frameworks to achieve the robust stability against residual modes and modal parameter errors, and their feasibility has been proved.
Journal ArticleDOI
On-orbit system identification experiments on Engineering Test Satellite-VI
TL;DR: It will be shown that the subspace method proves to be promising for the system identification of large space structures typified by ETS-VI.
Patent
Non-contact data carrier and method of fabricating the same
TL;DR: In this article, a non-contact data carrier includes a semiconductor device, a coil antenna, and a sealing resin coating (SRC) covering the semiconductor devices and the coil antenna.

TL;DR: In this article, a smelting reduction method is proposed to charge a carbonaceous material and an ore into a reacting furnace to directly contact the carbonized material and the ore, reducing the ore until at least a part of the ore is metallized.
Patent
Flat electrochemical cell
TL;DR: In this paper, a flat electrochemical cell which sufficiently secures airtightness and steam barrier performance inside an outer package using the outer package in which a laminate consisting of a composite film is made into a bag shape or a tray shape, and prevents blowing-out of the inner package due to increase of internal pressure by releasing the gas inside and also prevents leakage of electrolyte.
