Abstract: A charging stand is a power supply facility that is storable under a ground, and includes: a power supply unit (including a connector, a power supply cable and a power supply circuit) for supplying electric power to a vehicle on the ground; and a control device that controls supply of the electric power by the power supply unit. The control device allows the supply of the electric power by the power supply unit when the water is not accumulated inside the charging stand. With the above, when the water is not accumulated inside the charging stand, the power supply unit can supply the electric power to the vehicle.

Abstract: A power supply system includes charging stands capable of supplying electric power to an electrified vehicle on the ground and each including a power supply unit, a movable unit including the power supply unit and moving between a first position at which the power supply unit is housed underground and a second position at which the power supply unit is exposed from the ground, an actuator moving the movable unit, and a control unit controlling the actuator. The control unit controls the actuator to lower the movable unit to the first position when supply of electric power to a next electrified vehicle is not scheduled within a predetermined period after the supply of electric power and controls the actuator to maintain the movable unit at the second position when supply of electric power to a next electrified vehicle is scheduled within the predetermined period after the supply of electric power.

Abstract: A method of production of a silicon carbide single crystal enabling fast, stable, and continuous growth of a high quality silicon carbide single crystal and enabling both an increase in size of the bulk single crystal and an improvement of quality of a thin film single crystal, comprising stacking, in order from the bottom, a silicon carbide source material rod, a solvent, a seed crystal, and a support rod supporting the seed crystal at its bottom end so as to form a columnar workpiece, heating a bottom end of the source material rod as a bottom end of the columnar workpiece, and cooling a top end of the support rod as the top end of the columnar workpiece so as to form a temperature gradient inside the columnar workpiece so that the top end face becomes lower in temperature than the bottom end face of the solvent; and causing a silicon carbide single crystal to grow continuously downwardly starting from the seed crystal, wherein said method further comprises using an inside cylindrical susceptor tightly surr

Abstract: The present invention provides an oxide semiconductor electrode which can realize a combination of high transparency with large surface area and is highly responsive to ultraviolet light, as well as to visible light. The oxide semiconductor electrode comprises a conductive substrate and an oxide semiconductor layer provided on the conductive substrate. The oxide semiconductor layer is a porous layer comprising porous titania particles which have been joined to each other to define interparticulate communicating pores. Preferably, the pores possessed by the titania particles per se have a diameter of 10 to 40 nm, the interparticulate communicating pores have a diameter of 10 to 70 nm, and the titania particles have an average diameter of 10 to 70 nm.

Abstract: A ceramic heat insulating layer formed on an iron-based base material with or without a bonding layer interposed therebetween, comprising: aggregate particles of a nepheline mineral; and a binder composed of silica particles and of a metalloxane polymer, the binder filling spaces between the aggregate particles and chemically bonding the aggregate particles to each other and to the base material or to the bonding layer. Alternatively, the binder leaves voids between the aggregate particles, and a sealing layer seals the voids in a surface region of the ceramic heat insulating layer.
