Abstract: An array of photovoltaic radiation detectors and a method of fabricating same. The array 10 includes a substrate 12 substantially transparent to radiation having wavelengths of interest and a radiation absorbing base layer 14 having a first surface 14a overlying a surface of the substrate for admitting incident radiation into the base layer. The base layer is comprised of a compositionally graded p-type Hg 1-x Cd x Te material wherein x equals approximately 0.6 to approximately 0.8 at the fist surface and equals less than approximately 0.4 at a second surface 14b. A cap layer 16 overlies the second surface of the radiation absorbing base layer, the cap layer also being compositionally graded. The cap layer has a bandgap that increases in width as a function of distance from the second surface of the base layer. The array further includes a plurality of regions 18 formed through the top surface of and substantially wholly within the wide bandgap cap layer, each of the regions forming a p-n junction 18a with the underlying material of the cap layer for collecting charge carriers.

Abstract: In conventional moving-image encoders, image areas are displaced block by block and it is not taken into account whether moving or unmoving image content exists within such blocks. In the process according to the invention, moving image contents are detected with the aid of an object mask and displaced independently of the surrounding unmoving image background. Instead of a block-oriented predicted image, an object-oriented predicted image is determined. For this purpose, shape and type of the moving image content is determined in the receiver from the motion information normally transmitted and the conventionally decoded image sequence and stored in an object mask which continuously tracks moving objects. Using this object mask, an improved display image can be generated by copying the image background from an image store. The method according to the invention leads to a qualitatively improved reproduction of coded moving-image sequences. In addition, intermediate images can be generated in which moving image content is also displaced independently of the image background.

Abstract: A thermal ink jet printhead (Figs 1 and 2) has heating element structures (18) which space the portion (33) of the heating element structures subjected to the cavitational forces produced by the generation and collapsing of the droplet expelling bubbles (26) from the upstream electrode interconnection (36) to the heating element. In one embodiment (Figs 4 and 4B) this is accomplished by narrowing the resistive area where the momentary vapor bubbles are to be produced so that a lower temperature section (34) is located between the bubble generating region (33) and the electrode connecting point (36). In another embodiment (Fig. 5), the electrode (17) is attached to the bubble generating resistive layer (31) through a doped polysilicon descender (38). A third embodiment (Fig. 6) spaces the bubble generating portion (54) of the heating element from the upstream electrode interface, which is most susceptible to cavitational damage, by using a resistive layer (52,54) having two different resistivities.

Abstract: There is disclosed a highly selective hydrogenation catalyst composition synthesized by adding an organometallic reducing agent, e.g., triethylaluminum, to a transition metal compound, e.g., nickel (II) octoate. The catalyst composition is synthesized either by adding the organometallic reducing agent to the transition metal compound, in that order, as rapidly as possible, or by adding the reducing agent and the transition metal compound, separately but substantially simultaneously, at substantially constant molar ratios to the catalyst synthesis vessel. The catalyst composition is subtantially more selective in hydrogenating mono-substituted and symmetrically disubstituted polymer double bonds in the presence of unsymmetrically disubstituted double bonds and double bonds having three or more substituents, and substantially more stable over extended periods of time at ambient conditions than prior art catalysts.

Abstract: The bit map description for a page printer (1) from data for more lines per page than would normally fit on the page is composed by reserving the full vertical height of one line and determining the line spacing on the basis of the ratio (division) of the remaining printable page length to the number of lines less one. This is done automatically by a microprocessor (7) which determines the lines per page from the page selected from the control panel (13), performs the division of lines per page less one into printable height less one, followed by page composition based on the result. The data invariably fits into the mapped description without additional operator intervention.
