    • PURPOSE: To disperse impurities by utilizing magnetic force, to obstruct cohesion and to improve combustion efficiency by burning fuel oil while working a line of magnetic force to fuel oil, in a fuel tank in a combustion apparatus for an oilstove, etc. or in a path up to a combustion section from the fuel tank.
      CONSTITUTION: The inclination of prolongation of combustion time is obtained by working a line of magnetic force of 800 gauss or more to fuel oil. 1,000 gauss or more is preferable, and 6,000 gauss at a maximum and approximately 5,000 gauss to the utmost are sufficient as an upper limit from the points of the treatment of a magnetic substance and adhesive property, etc. between an oilstove, etc. and an external metal. The magnetic substance 6 is charged directly into fuel oil 4 in order to work the line of magnetic force to fuel oil, and the contact of both is the most effective. It is preferable that the magnetic substance 6 is mounted while being isolated to the inside by a necessary distance, normally, 3cm or more, from the outer circumferential surface of the oilstove or coating the outer circumferential surface in order to easily mount or demount the magnetic substance or prevent the effect of magnetic force on the outside of the oilstove and an adhesion with the external metallic body of said stove.

    • For topographic processing, a plurality of maps are stored, the maps being of different scales and therefore being based on different amounts of map data. The user selects a map of appropriate scale, and can then select a part, for example a line, on which appropriate analysis is to be made, such as obtaining a cross section based on contour data of the map. The map data corresponding to the selected part of the map is investigated and, where it does not meet an appropriate criterion, the data of a part of a map of different scale is investigated, the part of the two maps corresponding to the same region. Hence information can be derived which meets the appropriate criterion. Thus, when obtaining a cross section, if the amount of data for a region of a map is insufficient for a satisfactory cross section to be obtained, the data of the same region of a map of larger scale is analyzed, so that a satisfactory cross section can be achieved. The processing is also applicable to the investigation of lines of sight, using the map data.
    • 对于地形处理,存储多个地图,地图具有不同的尺度,因此基于不同数量的地图数据。 用户选择适当比例的地图,然后可以选择要在其上作出适当分析的部分,例如线,例如基于地图的轮廓数据获得横截面。 研究与地图的选定部分对应的地图数据,在不符合适当标准的情况下,对不同尺度的地图的一部分的数据进行调查,对应于同一区域的两幅地图的一部分。 因此,可以导出符合适当标准的信息。 因此,当获得横截面时,如果地图的区域的数据量不足以获得令人满意的横截面,则分析较大比例的地图的相同区域的数据,从而满足交叉 部分可以实现。 该处理也适用于使用地图数据的视线调查。

    • An apparatus for driving an A.C. motor includes a circuit for computing the sum of polyphase A.C. signals used to drive a pulse-width modulation circuit for controlling an inverter, and for limiting the amplitude of a current command when said sum is other than zero. When an imbalance occurs in the polyphase A.C. signals, the current command amplitude is immediately limited in accordance with the state of the imbalance to prevent saturation of a current amplifier that is operable to produce the polyphase A.C. signals by amplifying the outputs of an arithmetic circuit. These outputs are difference currents obtained by computing the difference between polyphase command currents and corresponding ones of detected polyphase currents actually applied to the A.C. motor. Preventing saturation of the current amplifier assures that the polyphase currents actually applied to the A.C. motor will be held in a balanced state at all times.
    • 用于驱动交流电动机的装置包括用于计算用于驱动用于控制逆变器的脉冲宽度调制电路的多相交流信号的和的和用于当所述和不是零时限制电流指令的幅度的电路的电路。 当在多相交流信号中发生不平衡时,根据不平衡的状态立即限制电流指令幅度,以防止可操作以通过放大运算电路的输出来产生多相交点信号的电流放大器的饱和。 这些输出是通过计算多相指令电流和实际施加到交流电动机的相应检测到的多相电流之间的差而获得的差电流。 防止电流放大器的饱和,确保实际施加到交流电动机的多相电流始终保持在平衡状态。

    • A negative feedback control system includes a step of amplifying digital information by an amplifying operation at a high response speed and not including an integration. The negative feedback control system detects a predetermined amount of increase and decrease in the controlled variable, and outputs an increment signal or a decrement signal according to the predetermined amount of increase and decrease in the controlled variable, respectively, receives increment signals and the decrement signals from a controlled variable detecting unit 4, ignores the first successive n increment signals immediately after an arbitrary decrement signal, then begins to count each increment signal as a +1 unit from the n+1-th increment signal after the arbitrary decrement signal, and ignores the first successive n decrement signals immediately after an arbitrary increment signal, then begins to count each decrement signal as a -1 unit from the n+l-th decrement signal after the arbitrary increment signal (FIG. 2); whereby the vibration of the controlled variable is suppressed.
