    摘要： The invention relates to a photographic element comprising a light sensitive silver halide emulsion layer having associated therewith one or more dye-forming couplers and a stabilizer compound of formula (I): wherein R1 and R2 are independently selected from hydrogen or an unsubstituted or substituted alkyl, aryl, alkoxy, aryloxy or amino group or may combine to complete a 5-10 membered heterocyclic ring which may contain in addition to the silicon atom one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted; each Z independently represents the atoms necessary to complete a substituted or unsubstituted arene or heteroaromatic ring system; X is a single bond or a linking group having a single atom which connects the arene rings or heteroaromatic ring systems; or X forms, together with substituents ortho to X on the arene rings or heteroaromatic ring systems, a fused unsubstituted or substituted 5-, 6- or 7-membered ring, which may contain one or two heteroatoms selected from nitrogen, oxygen and sulfur. The stabilizer is used to enhance the image stability of the dye formed from a cyan, magenta or yellow dye-forming coupler without significantly degrading other photographic properties.

    摘要： There is provided a photographic element comprising at least one silver halide emulsion layer having associated therewith a novel phenolic cyan dye-forming coupler of formula (I) wherein X is hydrogen or a group that can be split off by the reaction of the coupler with an oxidised colour developing agent, and one of Y and Z is the group  wherein each R is independently an unsubstituted or substituted alkyl or aryl group or a 5-10 membered heterocyclic ring which contains one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted; R1 is hydrogen or an unsubstituted or substituted alkyl or aryl group, R2 is an unsubstituted or substituted alkyl or aryl group or a 5-10 membered heterocyclic ring which contains one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted; R3 is hydrogen or an unsubstituted or substituted alkyl or aryl group, n is 1 or 2, and the other of Y and Z is an unsubstituted or substituted alkyl or aryl group or a 5-10 membered heterocyclic ring which contains one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted. The couplers for use in the element of the invention yield cyan images of good hue, with good stability to heat, humidity and light, whilst retaining the other properties desirable for good photographic performance.

    摘要： An apparatus includes an electrostatic discharge (ESD) protection device configured to protect a circuit from ESD conditions. The protection device includes an emitter region having a first diffusion polarity; a collector region laterally spaced apart from the emitter region, and having the first diffusion polarity; and a barrier region interposed laterally between the emitter region and the collector region while contacting the emitter region. The barrier region has a second diffusion polarity opposite from the first diffusion polarity. The device can further include a base region having the second diffusion polarity, and laterally surrounding and underlying the emitter region and the barrier region. The barrier region can have a higher dopant concentration than the base region, and block a lateral current flow between the collector and emitter regions, thus forming a vertical ESD device having enhanced ESD performance.

    摘要： A method of transmitting data according to a data transmission protocol wherein the data is transmitted as a plurality of data frames and each data frame includes an error checking field comprising at least two sub-fields, the data of the first sub-field being formed by a first error checking method performed on data of the frame and the data of the second sub-field being formed by a second error checking method performed on the said data of the frame, the first and second methods being such that the data of the first sub-field has different error checking properties from those of the data of the second sub-field.
