Conventionally, waveguide terminals formed in a plurality of dielectric substrates are joined together by mounting the dielectric substrates on carriers and fastening them to a waveguide adapter with screws. In the present invention, to reduce cost and improve machinability, a plurality of solders 7 are disposed around the waveguide terminal 2b formed in one dielectric substrate 1b, and the other dielectric substrate 1a having the waveguide terminal 2a is placed across the solders 7 to thereby c...

The present invention is a coupler built on a semiconductor substrate, e.g. GaAs. Semiconductor processing allows for small trace and space rules. The tighter design rules provide for tighter coupling than can be achieved by ceramic processes. The greater coupling allows for a shorter through line and with less loss, thus closer to ideal coupling.

A fluid coupler has a female coupler member and a male coupler member which can be connected to the female coupler member by simply being inserted into the female coupler member. The female coupler member includes a first locking ball, a second locking ball and a locking ball confining ring. The confining ring has a first slanted inner surface engaging the first locking ball to partly project the first locking ball into a male coupler member receiving hole of the female coupler. The confining ri...

An apparatus for coupling ends of a first hose and a second hose. The apparatus comprises a male coupler configured to attach to the first hose, and a female coupler having an inner cavity and being configured to attach to the second hose in the inner cavity by way of a first ferrule assembly. The first ferrule assembly comprises an outer ferrule positionable on an outside surface of the second hose proximate a first end of the second hose, and an inner ferrule positionable on an inside surface ...

A dripless coupler containing a female and a male coupler, the female coupler retained within a housing. The female coupler includes a receptacle enclosing a cavity having an inlet port, an outlet port and an open bore located at one end thereof. Positioned between the receptacle and the open bore is a movable seat which mates with a flat smooth end surface of the main poppet valve which is retained within the cavity. The main poppet valve is normally biased to a closed position against the mova...

A multipin coupler (50) includes upper and lower ring members (52, 54) with a plurality of cooperating pin connections (76) surrounding central openings therethrough such that the circuitry and corresponding probe card for testing an IC chip can be interconnected through leads of the same lengths having uniform impedances. Guide pins (68) are provided to assure proper alignment of the ring members (52, 54) before engagement of the pin connections (76). A pin and slot connection supports the uppe...

Complementary elongated members of generally semi-cylindrical cross-section are provided. These members are assembled on pipes to be joined so as to enclose the joint between the pipes, and the members include abutting edges extending lengthwise of the pipes and arranged to be bonded together. The coupler is provided with one or more recesses extending across the abutting edges of the elongated members. Reinforcing elements are received in each of these recesses and extend across the abutting ed...

A railway coupler housing includes a bottom wall section with a thrower hole extending therethrough and spaced from a side wall diverging outwardly from the horn line at the knuckle side of the housing. The side wall continues vertically from the bottom wall section at a rearwardly-spaced relation from the thrower hole along a sufficient height to permit a generally vertical dropping of the thrower within the interior of the coupler head for engaging a trunnion of the thrower in the thrower hole...

The present invention includes a coupler assembly for attaching a work implement to a work machine. The coupler assembly includes an attachment hook which has an upper jaw with an adjustment surface and a lower jaw with a locating surface. The adjustment surface of the upper jaw includes a plurality of interconnected arcuate notches therealong so that a pin receiving opening is defined between the adjustment surface and the locating surface. The plurality of arcuate notches in the adjustment sur...

A first embodiment of a waveguide coupler (10) has a substantially square cross-section with a width tapering from a first width a at a first end (12) to a smaller width b at a second end (14). Each side of the square waveguide coupler is provided with a turnstile port (16). The first end is coupled to a first waveguide (18) to couple the turnstile ports with the first waveguide, while the second end is coupled to a second waveguide, coupling the first and second waveguides together. Signals thr...
