    • Provided is a polyoxamide resin which has excellent impact resistance and is characterized in that the polyoxamide resin is obtained from a diamine in which the diamine component has 10 to 18 carbons and in that the polyoxamide resin has a relative viscosity (ηr) of 2.1 or greater as determined at 25° C. using 96% sulfuric acid as a solvent and a solution having a concentration of 1.0 g/dL, and also provided is an impact-resistant part comprising this resin. The polyoxamide resin has a higher molecular weight than a conventional polyoxamide resin, a large moldable temperature range as estimated from the difference between the melting point and the thermal decomposition temperature and therefore excellent molten moldability, and furthermore excellent impact resistance when compared to a conventional aliphatic polyoxamide resin without losing the low water absorbency, chemical resistance, hydrolysis resistance, high elasticity, and high strength seen with aliphatic straight-chain polyoxamide resins.

    • Each of the M basic vectors in a noise code book 260 is multiplied by a factor ±1 in a sign adder 270 and combined in an adder 280 to create 2M noise signed vectors. The characteristic of the binary Gray code is utilized as follows. A change ΔGu obtained between a noise signed vector based on a signed word i of the binary Gray code and a noise sign vector based on a sign word u adjacent to the sign word i and different from the sign word i only in a predetermined bit position v is used in such a manner that a sign word u′ which is next to reverse the bit position v on the Gray code sequence can express a change ΔGu′ from the noise signed vector by utilizing the fact that the sign word u′ differs from the sign word u only in one bit position w excluding the bit position V. Thus, calculation is simplified, increasing the vector search speed.
    • 噪声码本260中的每个M个基本矢量在符号加法器270中乘以因子±1,并在加法器280中合成,以产生2M个噪声带符号矢量。 二进制格雷码的特征如下。 基于二进制格雷码的有符号字i的噪声有符号矢量和仅与符号字i相邻的符号字u的噪声符号向量获得的变化DeltaGu,并且仅在预定位位置 v以这样一种方式使用,即接下来使格雷码序列上的位位置v反转的符号字u'可以通过利用符号字u'与噪声带符号矢量不同的事实来表示来自噪声带符号矢量的变化DeltaGu' 符号字u仅在排除位位置V的一位位置w中。因此,简化了计算,增加了矢量搜索速度。

    • A display unit includes a transparent hollow tube member and at least one display element sealed in the transparent hollow tube member. The display element is capable of rotating independently in the hollow tube member. Also, the display element has a surface which is divided into a plurality of areas having different colors and is polarized to have at least two poles having a different electrification state. An image formed by a display device including the display units is kind to the eye in the same way as printed matter, and does not cause eyestrain due to flickering of emitted light.
