In the conventional conveyance system, noise, friction and vibration occur under operation. We have developed the hybrid magnetically levitated system. In this system, pinning force of high temperature bulk super conductor is used for the levitation and guidance. This system needs no control system for levitation and guidance. To increase levitation force,(More)
A basic experimental device for a flywheel system using high temperature superconducting material (HTSC) is introduced. In this system, a circular shaped permanent magnet is installed on the rotor, and a YBaCuO plate is used for the stator. To increase the levitation force of the flywheel, an additional circular permanent magnet is installed under the(More)
The present state of studies on the chromatographic separation of phosphorus oxoacids is surveyed. In this paper, chromatographic techniques are divided into four groups, i.e. paper and thin-layer chromatography, paper electrophoresis, ion-exchange chromatography, and gel chromatography. The separation mechanisms and characteristics for these(More)
Jntroduction T h e three dimensional oscillation of the rotor in the HTSC-permanent magnet flywheel system is studied. The magnetic levitation using pining force of the HTSC bulk material has an advantage t o arheive stable levitation without control[l]. But the transient characteristics of the levitation is not clearly understood. As for the case of the(More)
We analyzed sediments and cavernicolous bivalve assemblages within cored sediments recovered from the Daidokutsu submarine limestone cave, which occurs in Pleistocene limestone on the fore-reef slope of Ie Island, off Okinawa, Japan. We found sand-sized brown grains within sediments aged 7,000–6,000 cal BP, and identified the grains as debris derived from a(More)
