Abstract: An apparatus for pulse width modulation comprises a delaying means (DL1-DL32) which receives a pulse (IP) and creates a plurality of modulated pulses. The pulse (IP) has a first pulse edge (t1) and a second pulse edge (t2). The apparatus further comprises a lookup table (66) for storing individual delay data for each of said plurality of modulated pulses, which delay data is communicated from the lookup table (66) to the delaying means (DL1-DL32). The delaying means (DL1-DL32) is responsive to the delay data from the lookup table (66) to delay only the first pulse edge of each pulse.

Abstract: An acoustic printhead comprises a matrix of drop ejectors configured in rows and columns, a plurality of row switches that are connected to control operation of the rows of the drop ejectors, and a plurality of column switches, connected to control operation of the columns of drop ejectors, wherein by selection of an appropriate row switch and column switch, a particular transducer of a specific drop ejector is turned on. The printhead further comprises a controller connected to the plurality of row switches and column switches, and a compensation network connected to the rows and/or columns of drop ejectors.

Abstract: An electronic compensation circuit in which a simulation of a laser's thermal droop characteristics is used to adjust input to the laser and thereby compensate for the laser's thermal droop effects The simulation circuit is conne cted to the laser either as an open loop circuit to provide a once only correction or as a closed loop feedback circuit to provide a continuous correction of the laser dro op effects. The simulation circuit is designed using either analog or digital circu itry and is adjustable to provide compensation for lasers having different time constants of droop or different values of droop.

Abstract: The vertical transistor (30) includes a substrate of a given first carrier type with an upper area and a lower area. A combination gate and source area has a centre where the combination gate and source area comprises a well region of a second carrier type. The source region is of the first carrier type, the first and second gate regions are of the second carrier type. The first and second pinch-off regions (44) are of the first carrier type. The first pinch-off region is in the centre with the first gate region (33) surrounding it, with the first source region (32) surrounding that, with the second gate region (34) surrounding that, and the second pinch-off region (46) surrounding that.

Abstract: A vertical transistor which is built in a substrate of a given first carrier type utilizing standard processes but which has a unique layout which facilitates high voltage, high current operation while still conserving space. The transistor is built utilizing a repeatable combination gate/source area that is built in the upper area of the substrate such that the remaining lower portion of the substrate underneath the combination gate/source area is the drain area of the transistor.

Abstract: A thermal inkjet printhead is disclosed having improved reliability and thermal efficiency. The printhead includes heating resistors and thin protective regionspositioned above the heating resistors for protecting the heating resistors fromcorrosion and cavitation damage from the ink. The heating resistors are positioned substantially within the geometric confines of the portion of the protective regions exposed to the ink. Positioned between the heating resistors and the underlying printhead structure are field oxide regions that thermally insulate the heating resistors from the underlying printhead structure. Positioned between the heating resistors and the underlying printhead structure is a passivation layer consisting of a middle layer of phosphorous glass, an underglaze between the middle layer and the underlying printhead structure, and glass mesas between the middle layer and theheating resistors. The underglaze helps prevent phosphorus from the middle layerfrom contaminating the underlying printhead structure. Similarly, the glass mesas prevent phosphorus from the middle layer from contaminating the heating resistors.
