摘要： A method of carrying out multilayer blooming which includes means to more accurately measure the thickness of the layers during blooming which consists in the use of a stack having at least one layer thereon to enhance the light transmission or reflection difference as the blooming layers are deposited on the stack during blooming of the articles, the stack preferably comprising a substrate having precoated thereon alternately high and low refractive index materials having an optical thickness of a quarter wavelength or multiples thereof at a selected wavelength.

摘要： An analogue multiplier stage which in use receives a first input signal represented by a pair of input currents and comprises a pair of current forks which divide the input currents in a predetermined ratio, the outputs the forks being cross-connected in one configuration to produce an output signal represented by a pair of output currents from the stage and representative of a product of the input signal and a term involving the ratio, and the fork outputs being cross-connected in the alternative configuration to produce a feedback signal which can be used to control the ratio by comparison with a second input signal.
