摘要： A chair is equipped with a leg column 1, a seat 3, and a back support 4. An intermediate supporting member 9 is fitted to an upper end of the leg column 1, the seat 3 and a back frame 5 are fitted to the intermediate supporting member 9, and the back support 4 is fitted to an upper end of the back frame 5 via a joint unit 11. The seat 3 has an elongated shape when viewed from the top, and is fitted to the intermediate supporting member 9 to swivel horizontally. The back support 4 can be turned freely around a first axis 13 and also can be turned freely around a second axis 12. Since the seat 3 and the back support 4 can be changed into various modes, a using mode of the chair can be changed variously.

摘要： A magnetic head includes a medium facing surface, a main pole, a trailing shield, a spin torque oscillator, and a first insulating layer. The first insulating layer is interposed between a portion of the main pole and a portion of the spin torque oscillator. The first insulating layer has a first end closest to the medium facing surface. The spin torque oscillator has a rear end farthest from the medium facing surface. The first end of the first insulating layer is located closer to the medium facing surface than the rear end of the spin torque oscillator is.

摘要： A plasmon generator including a wide portion and a narrow portion is manufactured by etching an initial plasmon generator using an etching mask. The etching mask includes a first mask layer for defining the shape of one of the narrow portion and the wide portion, and a second mask layer for defining the shape of the other of the narrow portion and the wide portion. The etching mask is formed by forming a first hard mask, a second initial mask layer and a second hard mask in this order on a first initial mask layer, and etching the first and second initial mask layers by using the first and second hard masks.

摘要： A magnetic head includes a main pole, an expansion member, and a heater. The main pole has an end face located in a medium facing surface. The expansion member is located farther from the medium facing surface than is the main pole and adjacent to the main pole in a direction perpendicular to the medium facing surface. The heater heats the expansion member. The expansion member has a linear expansion coefficient higher than that of the main pole.

摘要： A diffraction aberration corrector formed by the multipole of the solenoid coil ring and having a function of adjusting the degree of orthogonality or axial shift of the vector potential with respect to the beam axis. In order to cause a phase difference, the diffraction aberration corrector that induces a vector potential, which is perpendicular to the beam axis and has a symmetrical distribution within the orthogonal plane with respect to the beam axis, is provided near the objective aperture and the objective lens. A diffracted wave traveling in a state of being inclined from the beam axis passes through the ring of the magnetic flux. Since the phase difference within the beam diameter is increased by the Aharonov-Bohm effect due to the vector potential, the intensity of the electron beam on the sample is suppressed.
