摘要： A ferroelectric memory, upon reading of a memory cell array, in which the plate line PL is charged to the power supply potential VDD by a driving control circuit prior to driving of the relevant word line WL. The bit lines BL and /BL are charged to the potential VDD by a timing control circuit, then the word line WL is driven. At this time, the lines BL and /BL are discharged by applying an equalizing signal EQ with predetermined pulse width to a reset circuit.

摘要： A memory cell array includes ferroelectric memory cells arranged in m rows and n columns, bit lines provided along a row direction, and word lines and plate line provided along a column direction. The word lines are provided side by side so as to intersect each other at the border between the fourth row and fifth row. The arrangement allows the connecting of four ferroelectric memory cells to the same plate line and the same word line. Since the number of ferroelectric memory cells to be accessed simultaneously will be one-half the number of memory cells provided in one row, unnecessary access to the ferroelectric memory cells is reduced, to suppress deterioration of the ferroelectric memory cells. The word lines may instead intersect each other between the second and third lines, so that two ferroelectric memory cells are connected to the same plate and word lines.
摘要翻译：存储单元阵列包括布置成m行和n列的铁电存储单元，沿着行方向设置的位线，以及沿列方向设置的字线和板线。字线被并排设置，以便在第四行和第五行之间的边界彼此相交。该布置允许将四个铁电存储器单元连接到相同的板线和相同的字线。由于要同时访问的铁电存储器单元的数量将是一行中提供的存储单元的数量的一半，所以不利地访问铁电存储单元以抑制铁电存储单元的劣化。字线可以替代地在第二和第三线之间彼此相交，使得两个铁电存储器单元连接到相同的板和字线。

摘要： A vacuum circuit interrupter includes an evacuated envelope composed of a plastically deformable metallic cylinder and first and second insulating disks closing the opposite ends of the cylinder. Stationary and movable conductive rods project coaxially through the first and second disks respectively. Stationary and movable electrodes are connected to the stationary and movable rods in such a manner as to engage with each other when the movable rod moves toward the stationary rod and disengage with each other when the movable rod moves away from the stationary rod. A bellows surrounds the movable rod inside the envelope and is fixed at its one end to the movable rod and at its other end to the second disk in such a manner as to provide a seal about the movable rod to allow for movement thereof without impairing the vacuum inside the envelope. A first conductive shield surrounds the stationary rod inside the envelope. The first shield is fixed to the first disk in such a manner as to be isolated electrically from the stationary rod and the metallic cylinder. A second conductive shield surrounds the bellows. The second shield is fixed to the second disk in such a manner as to be isolated electrically from the movable rod and the metallic cylinder.
