A twin-clutch transmission wherein a center distance between input shafts and an auxiliary speed-change shaft can be shortened and the number of gears can be reduced. The processes described herein can form a metal-rich metal chalcogenide, such as, for example, silver-rich silver selenide. The liquid oligomerization feed stream is transported upwardly in the reactor vessel against gravity through a fixed bed of solid oligomerization catalyst under oligomerization conditions. The stapling apparatus further substantially reduces or prevents knife cut line bleeding by energizing a knife blade for cauterizing tissue while it is being cut. The scaler is coupled to the deinterlacer for selectively scaling data outputted from the deinterlacer. The method includes receiving and storing a first purchase request information set including an origin and a card number.
