    In the field of classificatory botany, there has been a case that classification of pine trees has been carried out by number of pine needles.
    Scales of a pine cone, on the other hand, have a spiral arrangement.
    This paper deals with spiral arrangement for the scales of the pine cone of the pine tree.It has been found that there are three kinds of the spiral arrangement for the scales.As a result, the spiral arrangement for them is also applicable to classification of the pine trees as well as number of the pine needle.

    Up to today, many types of letters and Japanese characters, such as mincho-, square gothic-, and round gothic-types, have been produced and used in daily work. These letters, however, are mainly described by hand lettering, for example, designers usually create letters with their skillful techniques.
    On the other hand, word processors are mostly used in many fields, such as in offices, laboratories and so on. The designers can not utilize the word processors for their making vector letters, because the letters by word processors are based on a dot matrix.
    The purpose of this study is to develope the expert system which can draw many types of high quality letters by using a micro-computer. The data of letters are stored on the 100×100matrix, where the starting, bending and terminal points of each stroke are stored in order of letter-description. The program calculates the edge lines and curves from the data. It can be said that many types of letters can be automatically drawn from the same data. Furthermore these letters can be magnified to any size, keeping their high quality, and also decorative letters can be produced with the technique of texture mapping.

    We propose a new animation method for making facial expressions using modified face method.
    Up to now, there have been many methods of generating animation by a computer.Most of them are, however, too complicated to apply to animate facial expression.
    We can make many animated sequences by using our method in which variables of modified face method are separated into facial feature variables and expression variables.
    This paper shows some results of facial expressions, for example, a sequence of “angry”.
