  • Patent number: 4188713
    Abstract: A metal tube with outwardly bent risers for terminals is filled with a body of plastic resin which hardens in place. Then the tube is cut through, chordwise, a plurality of times to provide a plurality of segments. An extended, base portion of the plastic resin body through which the risers extend radially outwardly continues to hold the cylindrical disposition of the metal segments, with gaps maintained therebetween. A shaft is fitted coaxially in the base portion of the plastic resin body and extends through a larger diameter central bore of the body, centrally of the commutator segments. The gaps communicate with the annular space between this bore and the shaft, for cleaning out of particulate debris by centrifugal force.

  • Patent number: 4052724
    Abstract: A branching filter for branching two microwaves from waves having two microwaves and a plurality of milliwaves includes two groups of coupling holes fluidically connected to one or more band-pass filters and a branching waveguide, one group of coupling holes being arranged on the wall of the conical horn so as to be equiangularly disposed thereabout with a 90.degree. interval defined between adjacent coupling holes when, for example, four coupling holes, filters, and waveguides are employed in such group, while the second group of coupling holes, disposed axially downstream of the first group of holes by means of a predetermined distance, is similarly disposed about the horn although angularly offset with respect to the holes of the first group through means of an angle of 45.degree..
