    • In an actuator drive control device for an active vibration isolation support system, accumulated time of eight time intervals tn of crank pulses which are outputted at every 15 degrees of a crank angle in a vibration period corresponding to 120 degrees of the crank angle, and average accumulated time shown by a straight line connecting a start point and an end point of the line of the accumulated time are calculated. Eight deviations Δtn are calculated by subtracting the average accumulated time from the accumulated time. A variation waveform of the deviations Δtn corresponds to a variation waveform of the time interval tn of the crank pulses attributable only to the engine vibration with the influence of a variation in the engine rotational speed Ne being eliminated. Therefore, the vibration isolation function of an active vibration isolation support system can be effectively executed by controlling an actuator of the active vibration isolation support system based on the engine vibration which is estimated from the variation waveform of the time interval tn. Thus, the active vibration isolation support system is precisely controlled by accurately estimating a vibration state of the engine when the engine rotational speed increases and decreases.
    • 在用于主动隔振支撑系统的致动器驱动控制装置中,在对应于曲柄角度的120度的振动周期中,在曲轴角度的每15度输出的曲柄脉冲的八个时间间隔tn的累积时间和平均 计算通过连接累积时间的线的起始点和终点的直线所示的累积时间。 通过从累积时间减去平均累积时间来计算八个偏差Deltatn。 偏差Deltatn的变化波形对应于仅消除发动机转速Ne的变化的影响的仅归因于发动机振动的曲柄脉冲的时间间隔tn的变化波形。 因此,通过基于从时间间隔tn的变化波形推定的发动机振动来控制主动隔振支撑系统的致动器,可以有效地执行主动隔振支撑系统的隔振功能。 因此,当发动机转速增加和减小时,通过精确地估计发动机的振动状态来精确地控制主动隔振支撑系统。

    • Discloses a silicon nitride based sintered body composed only of uniform, fine crystal grains, and improved in both strength and fracture toughness in the middle and low temperature ranges. A crystalline silicon nitride powder composed of crystal grains whose longer-axis diameter is not more than 200 nm or an amorphous silicon nitride powder is used as material powder. The silicon nitride powder is sintered at a temperature of 1200.degree. C. to 1400.degree. C. or sintered with a product of sintering temperature (.degree. C.) and sintering time (sec) below 600000 (.degree. C..multidot.sec) at a temperature of 1400.degree. C. to 1900.degree. C. Thus, a silicon nitride based sintered body in which the longer-axis diameter of silicon nitride and/or sialon crystals is not more than 200 nm is obtained.
