Abstract: Techniques are provided for x-ray sensing for intraoral tomography. A methodology implementing the techniques according to an embodiment includes detecting an x-ray pulse based on energy received at one or more pixels of a pixel array. The method also includes integrating the energy received at each of the pixels of the array of pixels, in response to the detection, wherein the energy received at each of the pixels is associated with the x-ray pulse. The method further includes multiplexing readouts of analog signals from the array of pixels into two or more parallel channels. The method further includes simultaneously converting (or otherwise in parallel) the analog signals of each of the channels into digital signals and storing the digital signals in memory as frames of data. The method may further include, for example, transmitting the frames of data from the memory, over a Universal Serial Bus, to an imaging system.

Abstract: The present invention relates to 1,2,4-oxadiazole derivative of the formula (I) ##STR1## wherein X represents a chlorine or fluorine atom or methyl group,Y represents a chlorine or fluorine atom,n is an integer of 1 or 3.The compounds of the invention have a extremely high selectively between paddy rice or crop plants and weeds, and a strong activity on various weeds. Moreover, the compounds have a very low phytotoxicity to paddy rice and crop plants.

Abstract: The present invention relates to amidoxime derivatives of the formula (I): ##STR1## wherein R.sub.1 is a C.sub.1-3 alkyl or allyl group, a methyl group substituted by chlorine or fluorine atom or ethoxycarbonyl or diethyldithiophosphate group, a phenoxymethyl group unsubstituted or substituted by chlorine atom, a C.sub.2 alkoxy or phenoxy group unsubstituted or substituted by chlorine atom or ethoxycarbonylethoxy group, a phenyl group unsubstituted or substituted by chlorine or fluorine atom, a benzyl group unsubstituted or substituted by chlorine atom, or a morpholine group; R.sub.2 is a phenoxymethyl or phenoxyethyl group substituted by chlorine atom, a phenyl group substituted by chlorine atom or methoxy group, or an ethoxy group. The compounds of the invention have a extremely high selectivity between paddy rice or crop plants and weeds and a strong activity on weeds. Moreover, the compounds have a very low phytotoxicity to paddy rice and crop plants.
