    • There are provided polyprenyl compounds of the formula ##STR1## wherein ##STR2## represent a trans-isoprene unit and a cis-isoprene unit, respectively, n is an integer of 11-19, Z.sup.1 and Z.sup.2 combinedly represent .dbd.O, .dbd.CH--COOH,.dbd.CH--COOR.sup.1, .dbd.CH--CN, .dbd.C(CN)COOR.sup.2, .dbd.CH--CO--NH.sub.2, .dbd.CH--CO--N(R.sup.3) (R.sup.4), .dbd.CH--CO--NHR.sup.5, .dbd.CH--CH.sub.2 --N(R.sup.3) (R.sup.4), .dbd.CH--CH.sub.2 --NHR.sup.5 or .dbd.CH--CHO or Z.sup.1 is a hydrogen atom and Z.sup.2 is --CH.sub.2 COOH, --CH.sub.2 COOR.sup.6, --CH(CN)COOR.sup.2, --CH.sub.2 CN, --CH.sub.2 --CO--NH.sub.2, --CH.dbd.CH--N(R.sup.3) (R.sup.4) or --CH.sub.2 --CH.dbd.N--R.sup.5, R.sup.1, R.sup.2 and R.sup.6 each being a lower alkyl group, R.sup.3 and R.sup.4 each independently being a lower-alkyl, cycloalkyl, aryl or aralkyl group or R.sup.3 and R.sup.4 combinedly representing an alkylene group containing 2-5 carbon atoms, and R.sup.5 being a lower-alkyl, cycloalkyl, aryl or aralkyl group. These polyprenyl compounds can be synthesized starting with a polyprenol obtainable from leaves of a plant such as Ginkgo biloba or Cedrus deodara by extraction and as necessary followed by hydrolysis, or a reactive derivative thereof. The polyprenyl compounds are useful as intermediates for the synthesis of dolichol without the use of an expensive C.sub.5 chain extender.
    • 提供下式的聚异戊二烯基化合物:其中,“IMAGE”分别代表异戊二烯单元和顺式异戊二烯单元,n为11-19的整数,Z1和Z2组合表示 = CH 2 COOR 1 = CH-COOR 1 = CH-CN = C(CN)COOR 2 = CH-CO-NH 2 = CH-CO-N(R3)(R4) NHR 5,= CH-CH 2 -N(R 3)(R 4),= CH-CH 2 -NHR 5或= CH-CHO或Z 1是氢原子,Z 2是-CH 2 COOH,-CH 2 COOR 6,-CH(CN)COOR 2,-CH 2 CN ,-CH 2 -CO-NH 2,-CH = CH-N(R 3)(R 4)或-CH 2 -CH = N-R 5,R 1,R 2和R 6各自为低级烷基,R 3和R 4各自独立地为低级 - 烷基,环烷基,芳基或芳烷基或R3和R4组合表示含2-5个碳原子的亚烷基,R5为低级烷基,环烷基,芳基或芳烷基。 这些聚异戊二烯基化合物可以从通过提取从植物如银杏叶或Cedrus deodara的叶获得的聚异戊二烯开始合成,并且根据需要随后进行水解或其活性衍生物合成。 聚异戊二烯基化合物可用作合成Dolichol而不使用昂贵的C5扩链剂的中间体。

    • A spread illuminating apparatus, in which a bar-like light conductive member brightened by a light emitting diode disposed at an end thereof is disposed close to the side of a transparent substrate made of light-permeable materials. The light conductive member is provided with a row of prism grooves as an optical path conversion means and an optical path conversion plate is disposed between the light conductive member and the transparent substrate. Light from the light emitting diode enters the light conductive member and is directed slantingly at the prism grooves to enter the optical path conversion means. Then, the light enters the transparent substrate straight to illuminate it efficiently.
    • 扩散照明装置,其中由设置在其一端的发光二极管增亮的棒状导光部件靠近由透光材料制成的透明基板的侧面。 导光构件设置有作为光路转换装置的一排棱镜槽,并且光路转换板设置在导光构件和透明基板之间。 来自发光二极管的光进入导光部件并被倾斜地指向棱镜槽以进入光路转换装置。 然后,光直接进入透明基板以有效地照亮。
