    摘要： An acceleration detector comprising a rotor rotatably supported within a housing and rotating against the urging force of a torsion spring based on acceleration, a pair of contact terminals contacting each other to be in an electrically connected state by rotation of the rotor at an inner end portion provided within the housing, and a supporting portion integrally formed with the rotor and supporting the torsion spring. The supporting portion is displaced by a predetermined amount in a predetermined direction from the rotary center of the rotor so that the spring effect center when torque is exerted on the torsion spring by rotation of the rotor substantially corresponds to the rotary center of the rotor. This construction of the acceleration detector produces the desired performance approximating the design value in an acceleration detector.

    摘要： A casting roll (18) for a twin roll continuous caster comprises a roll body (19) made of a metal material having high rigidity and a sleeve (20) made of a metal material having high thermal conductivity for covering an outer periphery of the roll body (19). A plurality of load bearing members (23) with thicker width are provided peripherally on the outer periphery of the roll body (19), the load bearing members (23) being in contact with an inner periphery of the sleeve (20) and extending axially of the roll. A plurality of fins (24) with thinner width and shorter in height than the load bearing members (23) are provided on the inner periphery of the sleeve (20) between the adjacent load bearing members (23) and extending axially of the roll, cooling water passages (25) being provided in the form of gaps defined between the roll body (19) and the sleeve (20) thereby providing a roll having sufficiently high rigidity to prevent or at least minimise damage of the cooling water passages when the solidified shells are brought together between the rolls and/or having an enhanced heat transfer area.
