Abstract: A syringe assembly includes a plate-shaped seal member that seals a distal opening of a distal nozzle portion of a syringe; and a tubular cover member. The cover member has a base portion and a mounting portion. The mounting portion has two claw portions, two first column portions arranged on both sides of one of the two claw portions, and two second column portions arranged on both sides of the other of the two claw portions. An outer peripheral portion of the mounting portion has two outer peripheral notch portions. An inner peripheral portion of the mounting portion has two inner peripheral recessed portions.

Abstract: A plate-fin-type heat exchanger for transferring heat from a hot fluid to a cold fluid includes stacked plates having fins therebetween that define alternate interdigitated first and second fluid passages, the fins defining the first fluid passages having a high coefficient of heat transfer and a large area of heat transfer and the fins defining the second fluid passages having a low coefficient of heat transfer and a small area of heat transfer. Either the hot fluid or the cold fluid is continuously passed through the first fluid passages and the other fluid is intermittently passed through the second fluid passages.
