Abstract: A variable magnification optical system comprises at least three optical units which are a first moving optical unit, a fixed optical unit and a second moving optical unit. The three optical units are arranged in that order in a propagation direction of light, and a variation of magnification is effected by a relative movement between the first moving optical unit and the second moving optical unit. If a ray which exits from an object and enters the variable magnification optical system, and passes through a center of a stop of the variable magnification optical system and reaches a center of a final image plane is represented as a reference axis ray, the second moving optical unit has a cross-sectional shape which is asymmetrical in a plane which contains the reference axis, and a curved reflecting surface which is inclined with respect to the reference axis, and the direction of the entering reference axis and the direction of the exiting reference axis of the second moving optical unit are parallel to each other and differ from each other by 180°, the variable magnification optical system being arranged in such a manner that a final image is formed after an intermediate image is formed at least twice.

Abstract: The structure of a compound is expressed as an atom connection table using an electronic computer. The structure is registered in a three-dimensional manner, making it possible to effect the interconversion between the atom connection table and symbols R, S that represent absolute configuration of asymmetric carbon atoms, or .alpha., .beta. that represent directions of substitution relative to the plane the ring. Namely, in the case of a ring compound, bonded atoms in the clockwise and counterclockwise directions, and bonded atoms in the upward and downward directions of the ring are stored in the separate predetermined registers. In the case of a chain compound, bonded atoms in the right and left directions, and bonded atoms in the upward and downward directions are stored in the separate predetermined registers. On the atom connection table, therefore, the rotational directing of bonded atoms can be defined as viewed from a given direction. It is therefore possible to prepare the atom connection table reflecting the symbols in the compound name, to store three-dimensional structures of compounds, and to process and produce the data.
