  • Patent number: 4631504
    Abstract: An impedance conversion transformer which comprises a ferrite core and a pair of coils wound about the ferrite core. The ferrite core has permittivity which reduces in proportion to increase in frequency within a band used and the pair of coils are wound in a bifilar arrangement so that the electric length of the coils becomes half-wave length. One of the coils has the opposite terminals electrically connected to each other and grounded and impedance variation and balanced to unbalanced conversion are achieved between the opposite terminals of the other coil.

  • Patent number: 4230916
    Abstract: A multiway change-over switch which comprises an insulated casing defining a switching chamber therein and having a lobed opening in an upper portion, an upper terminal positioned on the undersurface of the top wall of the switching chamber, a rocking change-over member received in the switching chamber in contact with the upper terminal, a lower terminal rockably supporting the rocking change-over member within the switching chamber, an insulated base member secured to the bottom of the casing to support the lower terminal for vertical movement, a coiled spring positioned between the lower terminal and base member to urge the lower terminal upwardly, and at least one pair of diametrically opposite peripheral terminals extending upwardly from the periphery of the base member to surround the rocking change-over member.
