Abstract: A method of starting up a system clock that has been generated by a phase-locked loop, and circuitry for accomplishing that method. A low frequency master clock signal is distributed to circuits that generate high frequency local clock signals. These circuits generate the high frequency local clock signals using phase-locked loops in a frequency multiplier configuration. Lock indicator circuitry determines when the phase-locked loop has locked onto the master clock signal and then enables output buffers that then provide the high frequency clock signals to components in the system which need those local clocks.

Abstract: A length mode drop on demand type ink jet print head includes a lower body portion formed of an active piezoelectric material and an upper body formed from an inactive material. The lower body portion, which includes a plurality of longitudinally extending projections, is poled in a first direction generally orthogonal to both its longitudinal and vertical axes. The upper body portion also includes a plurality of longitudinally extending projections. The lower and upper body portions are mated such that the lower and upper body projections are spaced interdigitally with each other. By mating the lower and upper body portions in this manner, a plurality of ink-carrying channels are formed. The ink jet print head further includes a controller for selectively applying an electric field across each of the lower body projections in the poling direction. When an electric field is applied across one of the lower body projections in this fashion, the projection imparts a pressure pulse to the ink-carrying channel associated therewith. The active lower body portion may be replaced with an inactive lower body portion, an active intermediate body portion which includes a plurality of longitudinally extending projections, each having a strip of conductive material along the top surface thereof, and a layer of conductive material mounting the lower and intermediate body portions together. Here, the intermediate body portion would be poled in its vertical axis and the electric field would be applied between the conductive strip and layer.

Abstract: An ink jet printhead is comprised of a lower body part (52) having a base section and a plurality of generally parallel spaced projections extending upwardly therefrom and an upper body part (54) having a top section and a corresponding plurality of generally parallel spaced projections extending downwardly therefrom. The top sides of the lower body projections (59) are conductively mounted to the bottom sides of the upper body projections (61) to form sidewalls which define a plurality of ink-carrying channels (70). Strips of a conductive adhesive (57) mount the lower and upper body projections together and a controller (80) is electrically connected to the strips to selectively impart either a positive, zero, or negative voltage to each strip. The lower body part (52) is formed using a piezoelectric material poled in a first direction (P1) generally perpendicular to the channels and the upper body part (54) is formed using a piezoelectric material also poled in the first direction (P2). By applying a positive voltage to a first strip of conductive adhesive and a negative voltage to an adjacent strip of conductive adhesive, first and second electric fields oppositely orientated to each other and normal to the direction of poling are produced in the lower and upper body projections which form first and second sidewalls for the channel, thereby causing the first and second sidewalls to deform in first and second channel expanding directions, respectively.

Abstract: A user interface of simplifying selection of speaker volume level and power conservation level in a computer system. An icon is presented for setting the speaker volume which includes a bar graph of relative speaker volume. By depressing left or right arrow keys the graph moves and the volume level of the speaker is changed. By depressing the down arrow key when setting the volume level, the speaker is beeped to allow for a level check during the setting process. A series of icons are used to indicate and select power conservation level. Each icon includes a battery with a faucet attached to the side of the battery. Different water flow rates indicate the various conservation levels. A human figure is located adjacent the faucet to indicate the user-customerized conservation level.

Abstract: A method of forming an outwardly tapered orifice (16) for a fully assembled ink jet printhead (10). A main body (12) portion and a cover plate (14) for an ink jet printhead (10) are mounted together such that the cover plate (14) covers an ink-carrying channel (22) which axially extends through the main body portion (12). First and second light beam capable of ablating the material used to form the cover plate (14) is generated and an ink-carrying channel (22) communicating orifice extending through the cover plate (14) and tapering outwardly from a front side of the cover plate (14) to a back side (14a) of the cover plate (14) is formed by directing the first and second light beams at the front side (14b) of the cover plate (14) at first and second angles, respectively, whereby the first and second light beams form the outwardly tapered orifice (16).
