Abstract: A power transmission cable with easy laying, reduced heat invasion and enhanced efficiency. The cable comprises an inner pipe 105 encasing a refrigerant passage 101, a superconducting member 102 and an electrically insulating portion 103; an outer pipe 106; a vacuum adiabatic insulating section 104 between the inner and outer pipes; an inner pipe support ring disposed between the inner and outer pipes so that it is slidable along the outer side of the inner pipe; an outer pipe support ring fixed to the inner side of the outer pipe; and a support member which is disposed between the inner and outer pipe support rings.

Abstract: Disclosed is a current-limiting circuit breaker including first and second mechanical switches connected in series with each other, a first diode, and a first snubber circuit, each connected in parallel across both ends of the first mechanical switch, and a second diode, and a second snubber circuit, each connected in parallel across both ends of the second mechanical switch.

Abstract: A superconducting cable having improved transmission efficiency facilitates the laying operation and reduces heat intrusion. The superconducting cable comprises a first pipe 105 within which are accommodated a refrigerant passage section 101, a superconducting member 102 and an electrical insulating section 103, and a second pipe 106 arranged on the outer side of the first pipe. A vacuum heat insulating section 104 is provided between the first and second pipes. The second pipe is formed of a ferromagnetic material.

Abstract: Disclosed is a semiconductor apparatus having a channel region of a substrate irradiated with light via a transparent gate electrode and a transparent gate insulating film to decrease channel resistance.

Abstract: Cutting method of ingot into wafers along cleavage plane. Onto surface of single crystal ingot 10 is implanted ion beam 23 to generate lattice defects in a direction defined by the crystal axes that corresponds to the cleavage plane. Cleavage is generated by applying a shock by a knife edge to the position of the lattice having a cutting face as a cleavage plane. Production time of waters is reduced with a more numbers of sliced wafers from one ingot.

Abstract: An apparatus and method which enhances the electron emission efficiency in a field emission apparatus having carbon nanotube(s) in a cathode as an electron emitting material. In a field emission apparatus having carbonanotube(s) as an electron emitting material on a cathode 2, the electron emission efficiency from the carbon nanotube(s) 1 is enhanced by irradiating carbon nanotubes 1 with infrared light.

Abstract: A process and apparatus assuring low costs and high efficiency in practicing refuse incineration. A applying electromagnetic wave of a frequency band resonant with rotation or vibration of a specific substance e.g., dioxins molecule, thereby to heat the dioxins molecule selectively up to high temperature to remove the dioxins molecule by decomposition.

Abstract: In a superconducting coil system an m×n array of wound cores are arranged and n pairs of strands, totalling at 2n strands, are passed in pairs through the hollow center of the cores so that the current will flow in mutually opposite directions in each paired strands. The system can reduce AC loss, completely avoiding current imbalance in strands and being designed easily.
