    • Provided is a regenerative switched reluctance motor driving system which allows a motor to have a reduced size and weight and an increased efficiency as well as improved energy recovery efficiency at the time of regenerative braking without using a neodymium magnet. Based on an angular position of a rotor in the motor, a constant current flip-flop circuit 2 renders two current paths alternately conductive so as to allow a rectangular-wave current having a width of an electrical angle of 180° to alternately flow in two coils in the motor 3, and shifts the timing of rendering the two current paths alternately conductive, between when driving and when braking the motor 3, by a time during which the rotor is rotated by an angle corresponding to an electrical angle of 180°. When driving the motor, a DC constant current power supply unit 1 discharges a DC power supply, while when braking the motor, it receives an input current through a negative terminal of the DC power supply, and outputs a DC current to the constant current flip-flop circuit 2, and further outputs a DC current regenerated from the motor 3 through the constant current flip-flop circuit 2 to a positive terminal of, and thereby charges, the DC power supply.

    • The invention relates to a storage apparatus comprising a storage shelf having a plurality of horizontally and vertically arranged storage sections for storage of articles and a moving body for taking articles in and out of the storage shelf. Conventionally, since an article carrying in and out section for taking articles in and out of such storage apparatus is divided into working sections having substantially the same width as that of storage sections, a space for work is small and a work is made difficult and inefficient when the moving body is used to take articles out of the storage sections or articles are placed on the working sections. Therefore, a working space, which protrudes beyond the article carrying in and out section and is free of partitions is provided. With such arrangement, however, there is a problem that a storage apparatus is extended in a lengthwise direction. An article carrying in and out section (4) of the storage apparatus according to the invention is formed by an opening which is opened accross a plurality of widths of the storage sections (1) between front and rear surfaces of the storage shelf provided with the article carrying in and out section, so that a large working space can be provided which is free of any portion protruding beyond the storage apparatus.
    • 本发明涉及一种存储装置,其包括具有多个水平和垂直布置的用于存储物品的存储部分和用于将物品进出存储架的移动体的存放架。 通常,由于将进出这种存储装置的物品带入和取出的物品被划分为具有与储存部分宽度基本相同的宽度的工作部分,所以工作空间小并且工作变得困难和低效 当移动体用于将物品从储存部分中取出或者物品放置在工作部分上时。 因此,提供了突出超出物品的进出部分并且没有分隔的工作空间。 然而,通过这样的安排,存在一种存储装置在长度方向上延伸的问题。 根据本发明的存放装置的进出部分(4)的物品是通过一个敞开的开口形成的,所述开口在储存架(1)的多个宽度上敞开,所述开口设置在所述储存架的前表面和后表面之间 物品携带和输出部分,从而可以提供没有突出超出存储装置的任何部分的大的工作空间。
