摘要： In this invention, an original image is read to be formed as a tour bit map, and the bit map is read out for each plurality of picture elements. Then, in the position to which the aforementioned unit plurality of picture elements corresponds on the original image, a predetermined bit map data is to be written by a logical sum. If the operation is indicated as a shadowing process, a bit map of a predetermined oblique line for a shadow designated by a direction and a length is to be written. The aforementioned operation is carried out for every plurality of picture elements on the contour bit map so as to thicken or shadow the original image at a high speed. When the method of this invention is applied as to a large size region, since the work area for the reservation of the contour data becomes larger to exhibit less effectiveness of the space usage, the processing area is designed to be divided, if required, to be processed. In such a division method, it is required to set up as work areas a reservation area for keeping the contour bit map and a writing-in region for writing in the synthetic unit data in the use of the logical sum. Providing the latter mentioned writing-in region makes it possible to save a clipping treatment, and also give an advantage for effecting the thinning operation.

摘要： Compounds of formula (I): ##STR1## wherein: R.sup.1 is hydrogen or a hydroxy-protecting group; R.sup.2 is alkyl, alkoxy, halogen, optionally substituted phenyl or optionally substituted phenoxy; R.sup.3 is optionally substituted pyridyl, optionally substituted quinolyl or phenyl group which has a substituent of formula --CYNR.sup.5 R.sup.6, where Y is oxygen or sulfur, and R.sup.5 and R.sup.6 are each alkyl, aryl or aralkyl, or R.sup.5 and R.sup.6 and the nitrogen to which they are attached together form a heterocyclic group; is R.sup.4 hydrogen or an amino-protecting group; and Z is sulfur or oxygen; are valuable intermediates in the preparation of carbapenem compounds and retain a desirable configuration during conversion to such carbapenem compounds. Penem and carbapenem compounds having a group of formula --SA' are prepared from a corresponding compound having a substituted thio, sulfinyl or sulfonyl group at this position by reaction with a compound A'SH (where A' is an organic group) in the presence of a salt of a metal of Group II or III of the Periodic Table.

摘要： A method for identifying and removing noise from digitized images includes the steps for judging whether or not a group of black pixels represents a noise by analyzing the number of pixels in the group, the degree of flattening of the group and the curvature of the region. According to the inventive method, since the entire region is scanned at once, allowing the detection of various sized pixel groups, the black pixel groups meeting a predetermined level can be selected and removed from a corresponding predefined region. Thus, noise can be removed from several predefined regions using a different noise level for each region.
