    Abstract: The problem to be solved by the present invention is to provide a highly-versatile method for producing a nitroxyl radical derivative, in which position-2 and position-6 in a TEMPO-based compound can be easily substituted, and further, a method for producing a nitroxyl radical derivative, in which a nitrogen nucleus is labeled with 15N. The above-described problem can be solved by reacting a triacetoneamine derivative with ketone or aldehyde in the presence of ammonium salt or a 15N-labeled compound thereof to obtain a 2,6-substituted-4-piperidone derivative.

    Abstract: An image encoding and transmitting system is an image transmission system for transmitting digital data such as TV telephones. The system for dividing input frame data into a plurality of blocks before transmitting them comprises on its sending side an intra-frame/inter-frame determiner for receiving intra-frame data and inter-frame data and selecting either of them for output, and a difference collator for having the intra-frame/inter-frame determiner compulsorily output intra-frame data at the time of data input for the next frame when one or more data in each block forming inter-frame data are larger than a predetermined threshold. The system also comprises on its receiving side an picture element domain frame data storage for storing received data in the picture element domain, and a motion vector detector for detecting according to the contents in the storage a motion vector using the data in the block surrounding the discarded block in order to guess the data in the discarded block.

    Abstract: This invention provides a transparent thermal recording medium, in which the transparent thermal recording medium comprises: a thermal recording layer, which is provided on a transparent layer, consisting essentially of an electron-donating chromophoric compound, an electron-accepting compound and binder resin; and a further-provided protective layer having an approximately equal refractive index to the refractive index of the thermal recording layer, wherein the binder resin is a compound having a group selected from a hydroxyl group and a carboxyl group. The transparent thermal recording medium can be effectively used for a block copy film, on which an image is formed, for plate-making, particularly, in photogravure, offset printing and screen process printing, because the transparent thermal recording medium has a contrast of light transmission factors between a color-imaging portion and a non-imaging portion, in which the contrast is not less than 50% at a wavelength ranging from 370 nm to 450 nm.
