摘要： A noise suppression cable includes an electrical wire, a first magnetic material including a pair of first surfaces formed along an axis direction of the electrical wire and a convex portion projecting from the first surfaces, and a second magnetic material including a pair of second surfaces disposed on a periphery of the electrical wire, the pair of the second surfaces contacting the pair of the first surfaces such that a tubular shape is formed by the first and second magnetic materials. The first magnetic material and the second magnetic material are configured to generate a compression stress in the convex portion of the first magnetic material by receiving an external force so as to reduce a relative permeability of the convex portion.

摘要： A door leading edge sensor comprises: a door leading edge elastic member which is attached to a front end portion of a door in a door closing direction and in which a cavity extending in a direction intersecting with the closing direction is formed therein; and a linear pressure sensitive sensor that is attached to the door leading edge elastic member and is disposed along the extending direction of the cavity. The pressure sensitive sensor comprises an insulator tube having such an elasticity as to be deformed in accordance with an elastic deformation of the door leading edge elastic member and plural conductive members fixed to an inner surface of the insulator tube. The plural conductive members are in a non-contact state when the insulator tube is not deformed and are in contact with each other when the insulator tube is deformed.

摘要： A current detection structure (1) includes a busbar (2) to flow a current therethrough, a magnetic detection element (3) to detect a strength of a magnetic field generated by the current flowing through the busbar, and a current detecting portion (7) to determine the current flowing through the busbar based on the magnetic field detected by the magnetic detection element. A through-hole (4) is formed penetrating the busbar such that a current path (5, 6) is formed on both sides of the through-hole. The magnetic detection element is disposed in the through-hole. The current detecting portion determines the current flowing through the busbar based on a strength of a synthetic magnetic field detected by the magnetic detection element. The synthetic magnetic field is produced by combining a magnetic field that is generated by a current flowing through the current path on the both sides of the through-hole.
