    • PROBLEM TO BE SOLVED: To compensate the degradation in the visual distance regulating power of a person of advanced age and to enable the person of advanced age to read all characters without replacing the spectacles by using auxiliary lenses simply when the person of advanced age wears only the spectacles for far and middle distances. SOLUTION: If the person of advanced age places the two auxiliary lenses of a focal length approximately equal to that of spectacle lenses for far and middle distances in front of the spectacles for far and middle distances, the person can read a newspaper of a close range. If one auxiliary lenses is half rotated around the axis of rotation between the lenses, the total three lenses with the lenses of the spectacles worn by the person overlap one another. As a result, the magnification equal to that of a magnifier can be obtained and further the reading of the fine characters is made possible. COPYRIGHT: (C)2003,JPO

    • PROBLEM TO BE SOLVED: To enable a doll to be moved at joints and to be manufactured at a low cost by equipping a hard skeleton with joint members and making the soft outer skin of a skin material formed so that prescribed movable joints are positioned on each neutral position. SOLUTION: This figure doll 10 is constituted of three main parts which are an upper half body skin made of soft polyvinyl chloride resin formed into a pose in which joints of shoulders and elbows are set on each neutral position, a lower half body skin made of soft polyvinyl chloride resin formed into a pose in which joints of crotches and knees are set on each neutral position, and a skeleton frame covered by those skins. The soft skins can be covered on the skeleton frame since a thin frame is adopted as parts forming the shape of the doll 10. Arms and legs of the doll 10 covered by the soft skin can be moved in about 180 deg. since the soft skin is formed at each of neutral positions.
