摘要： A method of image signal encoding by orthogonal transformation comprises the steps of carrying out orthogonal transformation of two-dimensional image signals on the basis of a predetermined orthogonal function, arranging transformed signals obtained by the orthogonal transformation in the order of sequency of the orthogonal function, and encoding the transformed signals respectively with an intrinsic code length. The transformed signals are classified into groups each of which is composed of the signals corresponding to approximately equal spatial frequencies. The code length is adjusted to a common value for each of the groups on the basis of values of the transformed signals in each of the groups.

摘要： A storage tank 1 is divided into oil and ballast water chambers 3, 4 by an elastic partition membrane 2. To prevent the membrane from blocking the oil and water intake/discharge ports 5, 6 during the final stages of loading or unloading, the internal edges and corners of the tank are chamfered by apertured partition plates, supported wire mesh screens or the like, and the intake/discharge ports communicate with the spaces defined behind such plates or screens.
