    • A process for the production of a silicon nitride sintered body which comprises heat-treating a stock of silicon nitride sintered body within a temperature range of from the temperature at which the internal friction of the stock exhibits a peculiar peak maximum minus 150.degree. C. to that plus 150.degree. C. A representative used in the process is one which is produced by mixing powdered silicon nitride with powdery sintering aids so as to give a powder mixture comprising 5 to 15% by weight (in terms of oxide) of at least one element selected from the group consisting of rare earth elements and aluminum, 0.5 to 5% by weight (in terms of oxide) of at least one element selected from the group consisting of Mg, Ti and Ca and the balance of Si.sub.3 N.sub.4, molding the powder mixture, and sintering the resulting compact in a nitrogen-containing atmosphere at 1500.degree. to 1700.degree. C.
    • 一种氮化硅烧结体的制造方法,其特征在于,在从所述坯料的内部摩擦显示出特有的峰值最大值-150℃到+ 150℃的温度的温度范围内,对氮化硅烧结体的原料进行热处理, 该加工过程中使用的代表是通过将粉状氮化硅与粉末状烧结助剂混合制成的代表物,从而得到包含5至15重量%(以氧化物计)至少一种 选自由稀土元素和铝组成的组的元素为0.5〜5重量%(以氧化物计),选自Mg,Ti和Ca中的至少一种元素,余量为Si 3 N 4,将粉末成型 混合,在1500〜1700℃的含氮气氛中烧结。

    • A cognitive function training unit including an eye-target showing unit for showing a movable eye-target on a display disposed in front of the subject's eye, an eye movement measuring unit for measuring a position and/or movement of the subject's eye, and a judgment unit for judging whether or not the subject can fixedly look at or follow the eye-target based on the position and/or the movement of the eye-target shown on the display and the position and/or the movement of the subject's eye measured by the eye movement measuring unit, and the eye-target showing unit shows the eye-target repeatedly while changing the position and/or the movement of the eye-target according to a judgment result of the judgment unit. Therefore, it is possible to show a suitable eye-target according to a symptom of a patient, whereby it is possible to conduct training efficiently.
    • 认知功能训练单元,其包括用于在被检眼的前方设置的显示器上显示可动眼目标的眼目显示单元,用于测量被检者的眼睛的位置和/或移动的眼动测量单元,以及 判断单元,用于基于显示器上显示的眼睛目标的位置和/或运动以及被测者的眼睛的位置和/或运动被测量来判断对象是否可以固定地观看或跟随目标对象 并且眼睛目标显示单元根据判断单元的判断结果改变眼睛目标的位置和/或移动,反复显示眼睛目标。 因此,可以根据患者的症状来显示合适的眼睛目标,从而可以有效地进行训练。
