    • A process for preparing cyclopentenolones in good yields which comprises treating a 4-hydroxy-4-R.sub.2 -5-R.sub.1 -2-cyclopentenone of the formula: ##STR1## wherein R.sub.1 is an alkyl group having not more than 6 carbon atoms, an alkenyl group having not more than 6 carbon atoms, an alkynyl group having not more than 6 carbon atoms or a group of the formula: ##STR2## (in which R.sub.3 is hydrogen, methyl or halogen) and R.sub.2 is a hydrogen atom or a methyl group, provided that when R.sub.2 is hydrogen, R.sub.1 is neither .alpha.-methylallyl nor .alpha.-methylpropargyl, in an aqueous medium in the presence or absence of a metal salt at a temperature of 20.degree. to 200.degree. C. to give the corresponding 2-R.sub.1 -3-R.sub.2 -4-hydroxy-2-cyclopentenone of the formula: ##STR3## wherein R.sub.1 and R.sub.2 are each as defined above.
    • 一种以良好的产率制备环戊烯酮的方法,包括处理下式的4-羟基-4-R2-5-R1-2-环戊烯酮:其中R 1是不大于6个碳原子的烷基,烯基 具有不超过6个碳原子的基团,具有不超过6个碳原子的炔基或下式的基团:其中R 3是氢,甲基或卤素,并且R 2是氢原子或甲基 条件是当R 2为氢时,R 1在20℃至200℃的温度下,在金属盐存在或不存在下,在含水介质中既不是α-甲基烯丙基也不是α-甲基炔丙基,得到相应的2-R1 -3-R2-4-羟基-2-环戊烯酮,其结构式如下:其中R 1和R 2各自如上所定义。

    • In a stereoscopic imaging device including a plurality of imaging optical systems, a wide-image in which a principal subject is shifted from the center is taken, and also, a tele-image in which the principal subject is enlarged is taken at the same time. A size of a wide-side frame W, that is, a size of an angle of view of a trimming wide-image is decided based on a size of a tele-side frame T, that is, a zoom magnification of a tele-side imaging optical system, a position of the wide-side frame W displayed in the decided size is arbitrarily moved depending on an instruction from an operation unit, an area delimited by the wide-side frame W moved to any position is clipped from a default wide-image, and thereby, the trimming wide-image is obtained. Thereby, the tele-image which is a telephoto image in which a desired subject is zoomed, and the trimming wide-image which is a wide-angle image in which the subject can exist at a position other than the center of the image are simultaneously obtained.
    • 在包括多个成像光学系统的立体成像装置中,拍摄主体从中心偏移的宽幅图像,同时拍摄主体被放大的远摄图像 。 基于远端侧框架T的尺寸,即远侧框架W的变焦倍率来决定宽侧框架W的尺寸,即修剪宽幅图像的视角的尺寸, 以决定的尺寸显示的宽侧框架W的位置根据来自操作单元的指示而任意移动,移动到任何位置的宽侧框架W界定的区域被从默认位置剪切 从而获得了修整宽幅图像。 因此,作为期望被摄体被放大的长焦图像的远摄图像和作为被摄体可以存在于图像中心以外的位置的广角图像的修整宽幅图像同时 获得。
