A time-of-flight mass spectrometer, for example, a MALDI-TOF spectrometer, measures the characteristics of the charge to mass ratio of ionized particles by measuring the time taken for the particles to travel a pre-determined distance. During the sliding movement of the first and second members, the first and second resilient elements are always compressed first to store energy and then expand automatically as the stored energy is released. A lift operatively couples at least three of the members together such that operation of the lift moves the three members together. The stemmer uses dynamic dictionaries constructed as lexical analyzer state transition tables to recognize the various allowable word parts for any given language in order to obtain maximum speed. The present invention relates to the composition or mycelium comprising the compounds of the invention. Because the polysilicon has an excellent etch selectivity with respect to the oxide layer, the gate electrode layer can be sufficiently protected during the etching of the oxide layer resulting in a good shoulder margin at the exposed upper edges of the silicon nitride gate mask layer.
