    • PURPOSE:To retain the buoyance almost constant with a gyro case of a liquid compensating for variation in the buoyance due to temperature changes by providing an expensible bag body having gas sealed inside in a float type gyro device. CONSTITUTION:An expansible bag body 25 such as ring-shaped bellows having a gas 24 such as helium sealed inside is fixed on a gyro ball 3. As the temperature of a liquid 22 rises above the set temperature with the outside temperature changing, the specific gravity of the liquid 22 decreases. But the gas 24 expands to inflate the expansible bag body 25 and the buoyance of the liquid 22 working thereon increases thereby compensating for a drop in the buoyance on the gyro ball 3 with a rise in the temperature.
    • 目的:为了通过在浮动式陀螺仪装置中提供一种具有密封在内部的气体的易燃袋体来补偿由于温度变化引起的浮力变化的液体的陀螺仪,保持浮力几乎恒定。 构成:将可膨胀袋体25,例如具有密封在内部的氦气等气体24的环状波纹管固定在陀螺球3上。随着外部温度变化,液体22的温度升高到设定温度以上时, 液体22的重力减小。 但是气体24膨胀以使可膨胀袋体25膨胀,并且其上加工的液体22的浮力增加,从而补偿陀螺仪3随着温度的升高而降低浮力。

    • PURPOSE:To improve target tracking performance by fitting one-side terminals of plural elastic bodies which extend and contract radially to a rotating body which does not vary in moment of inertia by rotation, and providing plural weights axially symmetrically with the elastic bodies. CONSTITUTION:When the rotating body 21 which rotates by external force rotates around a support shaft 22 at an angular speed w1 through a ball bearing 23, weights 24-27 with some proper mass are balanced at points depending upon the centrifugal force and spring forces of coil springs 28-35. When a coasting state is entered, the rotating speed of a rotor is to decrease, but the centrifugal forces which operate upon the weights 24-27 are weakened to shift the weights 24-27 in position inward and the inward movement of mass is caused, reducing the moment of inertia of the rotor. The rotating speed of the rotor is to increase by angular momentum conservation rule, and variation in the rotating speed of the rotor is extremely gentle eventually, so that the rotating speed decreases slowly.
    • 目的:通过将多个弹性体的单侧端子安装成径向延伸到旋转体的旋转体,通过旋转而不会发生惯性矩变化,并提供与弹性体轴向对称的多个重量来提高目标跟踪性能。 构成:当通过外力旋转的旋转体21通过球轴承23以角速度w1围绕支撑轴22旋转时,具有一定适当质量的重物24-27在取决于离心力和弹簧力 螺旋弹簧28-35。 当进入滑行状态时,转子的旋转速度降低,但是减轻了对重物24-27的作用的离心力,从而将重物24-27向内移动并引起质量的向内移动, 减少转子的转动惯量。 转子的旋转速度通过角动量守恒规则增加,最终转子转速的变化非常缓慢,从而使转速缓慢下降。
