Abstract: A cross-linked nucleoside of the present invention is a compound represented by the formula (I) below. The cross-linked nucleoside of the present invention is usable as a substitute for a phosphorothioate-modified nucleic acid, which has a risk of, for example, accumulation in a specific organ. The cross-linked nucleoside also has excellent industrial productivity.

Abstract: A device for generating a magnetic field includes at least one electric coil having electric conductors that are arranged along a circular arc within a first angular range and that deviate from the circular arc within a second angular range. At least one magnetic yoke is arranged along a part of the first angular range.

Abstract: A seat belt system capable of reliably preventing inadvertent engagement even on occurrence of erroneous insertion of a tongue plate. The seat belt system includes first and second buckle units respectively including tongue plates and buckle bodies. The buckle bodies respectively include: frames; ejectors; hook members making engagement with engagement holes formed at the tongue plates; and release buttons. A distance from an insertion front end to the engagement hole of the first tongue plate is longer than a corresponding distance at the second tongue plate. A distance from an abutment part to a pushing part of the ejector of the first buckle body is shorter than a corresponding distance of the ejector of the second buckle body. The ejector of the first buckle body includes suppression-specific projections for preventing pivotal movement of the hook member in a direction for making engagement.
