    摘要: The present stress in the turbine rotor is estimated at each control period, from the steam temperature and pressure at the turbine inlet. In addition, the future turbine inlet steam temperature or pressure is preestimated once every n.sub.T control cycles, for a given speed or load changing rate, making use of data concerning the changing rate of the turbine steam inlet temperature or pressure in relation with the change of the speed or load, which has been obtained by a learning of the past turbine operating condition. This future steam temperature or pressure at the turbine inlet is used as a factor for preestimating the future stress expected to be caused in the turbine rotor. The preestimation of the rotor stress is performed for a plurality of assumed speed or load changing rates. The turbine is controlled at the maximum speed increase-rate or load changing rate which would not cause the future stress preestimated over a given preestimation time to exceed a limit stress. An observation of the present stress is made at each control period to check whether the limit stress is not exceeded by the present stress.

    摘要: An apparatus for measuring the concentration of carbon dioxide in water that can correct a reduction in measurement accuracy based on deterioration of a pH indicator is provided. A carbon dioxide concentration measurement apparatus includes a deterioration determining section that measures a change rate ΔA0 of an isosbestic point absorbance A0 and determines that the pH indicator solution is deteriorated when the change rate ΔA0 is reduced by a predetermined reduction rate or more. After the deterioration determining section determines deterioration of the pH indicator solution, a pH value computing section computes the pH value of the pH indicator solution using a corrected pH computation expression for correcting a deterioration of the pH value of the pH indicator solution on the basis of the change rate ΔA0 of the isosbestic point absorbance A0.

    摘要: A kinetic-energy absorbing member absorbs the kinetic energy of a pull-in member such as a buckle or a lap anchor when reaching a bottom position. The kinetic-energy absorbing member, which includes a thin-walled tubular member that may be made of metal such as iron or aluminum, is arranged between a bracket and buckle. As the pretensioner is actuated, the buckle is pulled by a wire, thereby depressing the kinetic-energy absorbing member against the bracket so that the kinetic-energy absorbing member collapses and the kinetic energy of the buckle is absorbed when reaching the bottom position.

    摘要: A seat belt device including a shock absorbing mechanism to gently stop a pull-in member and to prevent a large impact force from being exerted on the pull-in member when the pull-in member is pulled in by a pre-tensioner. The device may include a wire pulled by operation of a buckle pre-tensioner at the time of an emergency, a buckle is pulled in towards a bracket while a cover contracts. Before the cover contracts to a maximum permissible contraction position, the buckle comes into contact with the free end of a shock absorbing member, and, then, is pulled in while the shock absorbing member is caused to contract. By the contraction of the shock absorbing member, the shock absorbing member absorbs impact energy of the buckle.
