The invention is related to phosphorus substituted compounds with antiviral activity, compositions containing such compounds, and therapeutic methods that include the administration of such compounds, as well as to processes and intermediates useful for preparing such compounds. Each pixel includes a light sensing component, a pressure sensing component, and a switch. Each IC is then separated from its wafer to form an IC die, and the IC dice are assembled into IC devices. However there is no need for the user to press them directly. The sample analyzing apparatus compares the measured result and the result calculated from the model, and properly executes the fitting, and determines the best model among the several models and then analyzes the characteristics related to the organic EL element. The registration station selected may also be based upon the thickness of the collation and a desired location for binding the collation.
