Abstract: An integrated circuit mixer which is impedance matched to a fundamental waveguide, utilizes a slot coupler and a coplanar transmission line to apply an RF and local oscillator signal to a Schottky-barrier diode. The IF signal which is available at the output of the Schottky-barrier diode is filtered by means of an RF bypass capacitor that is located on the dielectric substrate surface. At 110 GHz, a mixer module when mounted in the end of a waveguide horn, has an uncooled double-sideband (DSB) mixer noise temperature of 339.degree. K. and conversion loss of 3.8 dB.

Abstract: An adapter for a coin-operated machine is mounted on the front face of the machine and covers the region for receiving coins. The adapter comprises a slot on the upper portion thereof and a tortuous passageway leading to the region for receiving coins. The tortuous path comprises a first downwardly and laterally extending segment having a liquid permeable bottom wall. Preferably, a second downwardly and laterally extending segment extends beneath the first segment, the second segment having a liquid impermeable roof.
