A large-area superconductor magnetic shield comprising a plurality of small superconductor unit layers stuck onto the surface of a large-area substrate, wherein the external peripheral sections of the adjacent unit layers are overlapped mutually or the end sections of the adjacent unit layers are abutted mutually such that the adjacent unit layers do not make contact with one another. Compared with conventional magnetic shields, the magnetic shielding amount at the overlapping sections of the magnetic shield of the present invention is substantially greater.

A magnetic refrigerator comprising a magnet generating a high-intensity magnetic field, a tube-shaped superconducting magnetic shield, a magnetic working material and a reciprocating means for reciprocatively moving the superconducting magnetic shield or the magnetic working material, the magnetic refrigerator being arranged such that a magnetization process wherein the magnetic working material is magnetized in the high-intensity magnetic field and a demagnetization process wherein the magnetic working material is demagnetized by being accommodated in the hollow section of the magnetic shield are repeated by the reciprocating means so that the magnetic working material generates coldness.By using the property of a tube-shaped superconductor which can shield the magnetism of an external magnetic field passing through the hollow section of the tube and can generate a zero-intensity magnetic field in the hollow section, the magnetic working material magnetized in the high-intensity magnetic field generated by the magnet is inserted into the hollow section of the tube-shaped superconducting shield and is demagnetized in an adiabatic condition to generate coldness. This coldness is used to cool the target cold bath.

A method of emanating a sound from a vehicle includes detecting a transmission state and a brake state of the vehicle and determining whether a vehicle movement state indicates intent to move the vehicle from a stationary state based on the transmission state and the brake state. The method further includes emanating the sound when the vehicle movement state indicates intent to move the vehicle, and refraining from emanating the sound when the vehicle is in the stationary state and the vehicle movement state fails to indicate intent to move the vehicle.

A plasma processing method for processing a target substrate uses a plasma processing apparatus which includes a vacuum evacuable processing vessel for accommodating the target substrate therein, a first electrode disposed in the processing vessel and connected to a first RF power supply for plasma generation and a second electrode disposed to face the first electrode. The method includes exciting a processing gas containing fluorocarbon in the processing vessel to generate a plasma while applying a negative DC voltage having an absolute value ranging from about 100 V to 1500 V or an RF power of a frequency lower than about 4 MHz to the second electrode. The target layer is etched by the plasma, thus forming recesses on the etching target layer based on the pattern of the resist layer.
