    • A method and apparatus for mapping a moving direction by using sounds for people with visual impairments, in which a moving direction can be expressed multi-dimensionally by using sound information and can effectively assist people with visual impairments and the like in navigation tasks. A moving direction of a person carrying a device configured to output sounds is mapped by using a combination of sounds outputted from the device. A plurality of different sound information pieces are stored in association with three or more predetermined directions, respectively, a current position of the moving target device is identified, and then a moving direction of the device is identified. A sound obtained by combining two sounds in a ratio according to the identified moving direction is outputted on the basis of sound information pieces associated respectively with two adjacent directions sandwiching the identified moving direction among the predetermined directions.
    • 通过使用具有视觉障碍的人的声音来映射移动方向的方法和装置,其中通过使用声音信息可以多维地表达移动方向,并且可以有效地帮助人们在导航任务中具有视觉障碍等。 通过使用从设备输出的声音的组合来映射携带被配置为输出声音的设备的人的移动方向。 分别与三个或更多个预定方向相关联地存储多个不同的声音信息,识别移动目标设备的当前位置,然后识别设备的移动方向。 根据所识别的移动方向按照比例组合两个声音而获得的声音是基于分别与在预定方向上夹持所识别的移动方向的两个相邻方向相关联的声音信息来输出的。

    • Polybutylene terephthalate having good heat stability and excellent hydrolysis resistance is continuously produced in a series of a first reactor for reacting an aromatic dicarboxylic acid comprising terephthalic acid as a main ingredient or a derivative thereof with a glycol comprising 1,4-butanediol as a main ingredient, thereby producing an oligomer with an average degree of polymerization of 2.2 to 5, a second reactor for polycondensating the oligomer from the first reactor, thereby preparing a low polymerization product with an average degree of polymerization of 25 to 40, and a third reactor for further polycondensating the low polymerization product from the second reactor, thereby producing a high molecular weight polyester with an average degree of polymerization of 70 to 130, or followed by a fourth reactor for further polycondensing the polyester from the third reactor to an average degree of polymerization of 150 to 200, thereby producing a high molecular weight polyester. Another third reactor or a plurality of third reactors can be provided in parallel to the third reactor, thereby producing different kinds of polybutylene phthalate with different degrees of polymerization from that produced in the main line of the third and fourth reactors or adjusting operating conditions of each of a plurality of the third reactors to increase kinds, precise quality.
