  • Publication number: 20060077025
    Abstract: Tape-shaped superconducting wires are made by forming a superconducting film on the substrate. At least the superconducting film is slit, electrically separated into a plurality of superconducting film parts each having a rectangular cross section and arranged in parallel to form parallel conductors. This provides superconducting wires capable of containing AC loss. A superconducting coil is made by winding the superconducting wires described above, wherein the provision of a coil structure containing at least partially a part wherein the perpendicular interlinkage magnetic flux acting among various conductor elements of the parallel conductors by the distribution of the magnetic field generated by the superconducting coils cancel mutually enables a simple structure without transposition to cancel mutually the interlinkage magnetic flux by the perpendicular magnetic field against wires, to contain circulating current within the wires by the perpendicular magnetic field and to make shunt current uniform.

  • Patent number: 6186309
    Abstract: A coin discriminating device for discriminating put-in coins into a normal coin and a smaller coin, in which the maximum number of normal coins to be put-in can be easily changed. The coin discriminating device includes a turn plate having a cut-out portion and a coin discriminating pawl portion on a periphery thereof. A plurality of coin discriminating levers, each of which has an engaging portion able to engage with the coin discriminating pawl portion, abut against a periphery of corresponding received put-in coins in the cut-out portion, respectively. A biasing member biases a free end of the coin discriminating levers to a side of the turn plate, and a handle is provided for rotating the turn plate. A regulating member regulates a number of normal coins to be put in the cut-out portion of the turn plate, and a setting member is provided for setting the number of normal coins to be put-in.

  • Patent number: 5715925
    Abstract: A coin sorting device of an automatic vending machine which can easily change a price without changing the automatic vending machine or the coin sorting device, is disclosed. In the coin sorting device, each of a pair of coin sorting levers prevents rotation of the turn plate due to engagement of the engaging portion with the coin sorting pawl portion when a put-in coin is smaller than a normal coin. On the other hand, when a put-in coin is the normal coin, the engaging portion is arranged to ride over the coin sorting pawl portion due to a sliding contact of the normal coin following rotation of the turn plate. One of the pair of coin sorting levers is provided with a coupling pin which can couple or coupling-release the coin sorting levers.
