摘要： A fluid pump includes a chamber and a plunger extending into the chamber and supported for sliding movement on a suction stroke to introduce fluid into the chamber and on a discharge stroke to force fluid out of the chamber. A driver slides the pumping member in opposite directions. A seal ring is located between the chamber and the pumping member and permits the sliding movement of the pumping member. The seal ring has an outer annular portion having a generally flat cross-section, clamped in a wall of the chamber and an inner annular portion having a bulbous cross-section and in sliding sealing engagement with the pumping member.

摘要： A test key layout for finding open-via failures using an electron beam. Two types of test key layouts are designed. A first test key layout is used for finding open vias underneath even-numbered metallic layers while a second test key layout is used for finding open vias underneath odd-numbered metallic layers. A pair of neighboring metallic layers forms a group that has no direct electrical connection with other groups. The upper metallic layer in each group is in an open circuit state so that image contrast is enhanced.
