The beginning of using Complementary Metal-Oxide-Semiconductor (CMOS) process technology to implement Static Random-Access Memory (SRAM) which transistor number is six. And then reducing transistor number for increasing integration density, but it will diminish the stability of memory, and also may enhance the complexity of access circuit, thus increasing the power consumption. For increasing the integration density of SRAM, and according to the electrical characteristics of reduced transistor number therefore designing the memory possess low power consumption and its corresponding circuits, and then implementing an access system. If electrical characteristic of the other various memories are similar to SRAM, such as Dynamic Random-Access Memory (DRAM), so they can also use the corresponding access circuit of SRAM.

A liquid drain valve assembly for a charge air cooler includes a valve housing configured to couple to the charge air cooler, the valve housing having a condensate inlet configured to receive condensate from the charge air cooler, and a condensate outlet. A valve is disposed within the valve housing. The valve includes a diaphragm seated against an inner wall of the valve housing and movable between a first position enabling condensate to flow past the diaphragm and out the condensate outlet to selectively drain condensate from the charge air cooler when the charge air cooler is not in a boosted condition, and a second position preventing condensate flow out the condensate outlet when the charge air cooler is in a boosted condition to thereby isolate the charge air cooler from the atmosphere.

A vacuum-aided toilet comprises a toilet bowl, a deodorization pipeline, a flushing pipeline, a sensing switch (4) and a control device. A flushing port of the toilet bowl is communicated with the deodorization pipeline. The deodorization pipeline is communicated to a vacuum device. Inside the toilet bowl are provided a trap I (1.1), a trap II (1.2) and a draining port (1.3). The flushing pipeline being connected to the flushing port of the toilet bowl and the trap II (1.2), respectively. The sensing switch (4) is connected to a control device, which controls the deodorization pipeline and the flushing pipeline. An ejector (2.4) mounted on an air discharge pipeline (2.5) is directly driven by gas from an air outlet of a ventilating fan (2.2), so that vacuum is produced in a draining pipe. Thus the vacuum-aided toilet can save water and get rid of the odor.

A method of etching a substrate comprises forming on the substrate, a plurality of double patterning features composed of silicon oxide, silicon nitride, or silicon oxynitride. The substrate having the double patterning features is provided to a process zone. An etching gas comprising nitrogen tri-fluoride, ammonia and hydrogen is energized in a remote chamber. The energized etching gas is introduced into the process zone to etch the double patterning features to form a solid residue on the substrate. The solid residue is sublimated by heating the substrate to a temperature of at least about 100° C.
