Abstract: FIELD: balancing of crankshafts. SUBSTANCE: crankshaft to be balanced is mounted onto supports of the machine. Vibrations of shaft and shaft disbalance are determined while shaft rotates, moreover, disbalance is taken into account, when shaft is driven to end planes of correction. The shaft is balanced at different polarities of projections by correction of central counterweight and end counterweight with positive projection. Value of correcting weight for central counterweight is determined as product of value of negative projection and relation of distance between end counterweights to distance between central counterweight and end counterweight with positive projection. Value of correcting weight of end counterweight with positive projection is determined as a sum of value of positive projection and absolute value of negative projection, multiplied by relation of distance between central counterweight and end counterweight with negative projection to distance between central counterweight and end counterweight with positive projection. The crankshaft is balanced at negative projections by correction of central counterweight and one of end counterweights, for which product of absolute value of projection by distance to central counterweight has smaller value. Value of correcting mass of central counterweight is determined as product of value of projection of end counterweight non-corrected by relation of distance between end counterweights to distance between end and central counterweights corrected. Value of correcting mass of end counterweight corrected is determined as difference of absolute values of projection of counterweight corrected and product of value of projection of end counterweight non-corrected, after being multipled by distance between end and central counterweights non-corrected to distance between end and central counterweights corrected.

Granted: 1996-11-20
Abstract: FIELD: scanning electron microscopy; layer-by-layer visualization of deep microstructure of analyzed objects of primarily laminated structure, such as integrated circuits and other components of micro- and nano-electronics. SUBSTANCE: detector used for visualizing separate deep layers of objects subjected to nondestructive tests and diagnosis has set of N combined detecting conductor layers with small atomic number (such as carbon in graphite phase) and dielectric with small atomic number (such as carbon in amorphous phase) arranged near and around primary electron beam. Total thickness of this system should be greater than electron path through detector material at used accelerating voltage. Thickness of each combined layer should be equal to desired resolution corrected to atomic number ratio of object materials and detector. In this case, the following takes place: electrons reflected from various deep layers of object 1 and, consequently, having respectively different output energies are absorbed by various detecting layers of conductor 2 (in analyzed structure it is carbon in graphite phase), layer thickness 0.5 mcm) separated by intermediate layers of dielectric 3 (in analyzed structure it is carbon in amorphous phase, layer thickness 0.5 mcm). Electrons primarily passing through rectilinear path inside object are selected due to detector arrangement in immediate proximity of and around primary electron beam 4. Electrons absorbed by conductor layers are recorded in one of channels of multichannel DC amplifier 5. Back-reflected electron current recorded in certain channel primarily complies with image of separate deep layer of object whose depth and thickness are found by calculation proceeding from conductor layer number (that is, its distance from dielectric surface) and its thickness.
