An apparatus for forming a pattern has a scanning-time setter, a time-error detector, a scanning-time corrector, a pulse data selector, and a control pulse signal generator. In order to achieve the above mentioned object, the present invention provides a method for manufacturing an organic EL element comprising at least a patterned organic light emitting layer, wherein the patterning is conducted by etching with a protecting layer pattern laminated on an organic light emitting layer. In some embodiments, a vascular remodeling device includes a first section and a protruding section. If the correlation between the test image and the positive control image is greater than the correlation between the test image and the negative control image, the test assembly is assembled properly. Temperatures may be computed at various points in the multiprocessor system by monitoring activity information associated with various subsystems.
