Pressure-induced Superconductivity in the Iron-based Ladder Material BaFe2S3

Abstract: All the iron-based superconductors identified to date share a square lattice composed of Fe atoms as a common feature, despite having different crystal structures. In copper-based materials, the superconducting phase emerges not only in square lattice structures but also in ladder structures. Yet iron-based superconductors without a square lattice motif have not been found despite being actively sought out. Here, we report the discovery of pressure-induced superconductivity in the iron-based spin-ladder material BaFe2S3, a Mott insulator with striped-type magnetic ordering below ~120 K. On the application of pressure this compound exhibits a metal-insulator transition at about 11 GPa, followed by the appearance of superconductivity below Tc = 14 K, right after the onset of the metallic phase. Our findings indicate that iron-based ladder compounds represent promising material platforms, in particular for studying the fundamentals of iron-based superconductivity.

Vehicle steerable by movement of center of gravity

Abstract: The invention relates to a vehicle designed to travel back and forth and rotates by driving the right and left wheels in response to the position of center of gravity of an occupant on a step board moving from the center of the vehicle base. A vehicle steerable by the movement of center of gravity comprises at least a left wheel (4L) and a right wheel (4R) which are disposed on the same axis, a first drive motor (5L) and a second drive motor (5R) for rotationally driving the left and right wheels (4L, 4R), a vehicle base (2) having the left and right wheels disposed on the left and right sides thereof and having the first and second drive motors mounted thereon, a step board (3) disposed above the vehicle base (2) and adapted for a person to be mounted thereof, pressure sensors (6L, 6R, 7L, 7R) interposed between the vehicle base and the step board for detecting the movement of the center of gravity of the occupant, and a drive control means (10) for drive-controlling the first and second drive motors to effect straight travel and /or rotary movement on the basis of the detection signals from the pressure sensors. According to the invention, a mere body weight movement is enough to cause longitudinal travel and clockwise and counterclockwise rotations.

MgO/p-GaN enhancement mode metal-oxide semiconductor field-effect transistors

Abstract: We report the initial demonstration of an enhancement mode MgO/p-GaN metal-oxide-semiconductor field-effect transistor (MOSFET) utilizing Si+ ion-implanted regions under the source and drain to provide a source of minority carriers for inversion The breakdown voltage for an 80-nm-thick MgO gate dielectric was ∼14 V, corresponding to a breakdown field strength of 175 MV cm−1 and the p-n junction formed between the p-epi and the source had a reverse breakdown voltage >15 V Inversion of the channel was achieved for gate voltages above 6 V The maximum transconductance was 54 μS mm−1 at a drain-source voltage of 5 V, comparable to the initial values reported for GaAs MOSFETs

Vehicle Ego-Motion Estimation and Moving Object Detection using a Monocular Camera

Abstract: This paper proposes a method for estimating the ego-motion of the vehicle and for detecting moving objects on roads by using a vehicle mounted monocular camera. There are two problems in ego-motion estimation. Firstly, a typical road scene contains moving objects such as other vehicles. Secondly, roads display fewer feature points compared to the number associated with background structures. In our approach, ego-motion is estimated from the correspondences of feature points extracted from various regions other than those in which objects are moving. After estimating the ego-motion, the three dimensional structure of the scene is reconstructed and any moving objects are detected. In our experiments, it has been shown that the proposed method is able to detect moving objects such as vehicles and pedestrians

Fuel supply device

Abstract: A fuel supply device is obtained in which joint strength can be maintained in a joint portion of plural filter members configuring a fuel filter. A fuel filter with an overall bag shape is configured by welding together an upper face filter cloth a lower face filter cloth of the fuel filter at a welded portion. A sub tank upper side member and a sub tank lower side member nip the upper face filter cloth and the lower face filter cloth at a nipping position that is at a different position from the welded portion.
