    摘要： An ink jet printing ink is first formulated in concentrated form, and in this form it is subjected to stressful operating conditions such as an elevated temperature. This stress causes particle formation. After filtration to remove these particles, the final ink formulation is prepared, including for the first time ingredients which inhibit particle formation.

    摘要： A compact antenna system for use in connection with pay television reception comprises a resonant cavity including a small dipole, the latter being connected to a circuit board containing circuitry for converting the received pay television signal to a frequency usable by the television receiver of the subscriber. The member defining the cavity is affixed to the circuit board, which in turn is mounted upon a holder attached to the exterior of the structure in which the television receiver is located. The circuit board includes a preamplifier-filter stage to filter extraneous signals and to promote preamplification of the signal from the antenna. The preamplified signal goes to the input of a mixer and from there is filtered to the frequency of the channel selected by the user of the television receiver. At least one triangular circuit element is utilized in the preamplifier and in the mixer.

    摘要： Disclosed is a computer data interface (6) for connecting a handheld computer (4) and a desktop computer (2). The computer data interface includes a cable (8) having connectors (10 and 12) at each end thereof. Mounted in one of the connectors is an adapter circuit for receiving data signals from the handheld computer and transmitting the signals to the desktop computer at a voltage levels compatible with the desktop computer. Similarly, the adapter circuit receives signals from the desktop computer and transmits the signals to the handheld computer at voltage levels compatible with the handheld computer. The adapter circuit is powered by the desktop computer to prevent draining the batteries of the handheld computer.
