1. Design of Attitude Control Servomechanisms with Fluid Ring and CMG for Rigid Satellite
ABSTRACT: Satellites cover a wide range of space missions as remote sensing. Accomplishment of the mission depends on satellite's stability maintenance and direction. The main task of the attitude control system is to provide stability to the satellite against external disturbances. Such perturbations are caused due to aerodynamic drag, solar radiation and m

2. Analysis of magnetic force production in slider actuators combining analytical and finite element methods
The production of magnetic forces in a magnetic actuator is the focus of the present analysis. Magnetic circuit analysis is used to investigate the direction as well as the expected order of magnitude of the force that attracts the armature into the central portion of a stationary core. A sequence of finite-element based solutions is used to investigate magn

3. Desenvolvimento de um atuador magnetico para excitação sem contato de sistemas rotativos / A magnetic actuator development for contactless excitation in rotor systems
A magnetic actuator as excitation source in rotating systems is developed, in order to accomplish modal analysis and other studies involving contacless excitation. Although the use of magnetic systems to apply forces onto rotating machinery has been carried out with high performance level (for example, magnetic bearings), the development of a conveniently ea

4. Development of nano-meter motion control in Japan
Production machines for next generation LSIs such as 4G-DRAMs and for large liquid crystal displays such as 0.5mx0.5m size, and information equipment such as magnetic hard disks and DVDs must have the positioning accuracy of a nano-meter order. To realize such a high degree of the positioning accuracy, not only precision machine elements and mechanisms but a

5. Photoresponsive polymer–enzyme switches
The ability to photoregulate enzyme activities could provide important new opportunities for development of diagnostic assays, sequential bioprocessing, and lab assays in both traditional and microfluidic formats. We show here that the photoinduced changes in the size and hydration of a “smart” polymer chain coil can be used to regulate substrate access
