Abstract: An integrated circuit includes a first-type active-region structure, a second-type active-region structure on a substrate, and a plurality of gate-conductors. The integrated circuit also includes a backside horizontal conducting line in a backside first conducting layer below the substrate, a backside vertical conducting line in a backside second conducting layer below the backside first conducting layer, and a pin-connector for a circuit cell. The pin-connector is directly connected between the backside horizontal conducting line and the backside vertical conducting line. The backside horizontal conducting line extends across a vertical boundary of the circuit cell.

Abstract: A filter cup assembly includes a first cup having a one-way valve connected to a center of the underside of the first cup 10 and a filtering part is connected to the underside of the first cup. An adaptor is connected between the filtering part and a second cup. A presser includes a pressing plate connected with a rod, the pressing plate is inserted into the first cup to force contaminated water in the first cup to pass through the one-way valve, the filtering part and is collected in the second cup. All of the parts are threadedly connected to each other so that they can be separated individually. The first cup is sized to receive the second cup, the filtering part and the adaptor when not in use.

Abstract: A water filtering device includes a casing having a first space defined therein and an inner part is received in the first space. The casing includes an inlet at top thereof and an outlet at a lower end thereof. The inner part includes a cover and an inner tube is located therein. A second space is defined between the inner tube and the inner periphery of the inner part. Filtering particles are received in the second space. The inner part includes apertures defined through a lower end thereof and communicating with the first and second spaces. Water enters into the first space form the inlet and enters into the second space via the apertures and is filtered by the filtering particles. The filtered water flows over the open top of the inner tube and enters into the inner tube and flows out from the outlet of the casing.

Abstract: A connection device for connecting an extension tube to a faucet includes a first member connected to a faucet, a second member which is connected to the extension tube, and a connection member rotatably connected to the first member and fixedly connected to the second member. A positioning member is biased by a spring and received in an engaging recess in the second member. The first member has a plurality of notches so that the positioning member is engaged with one of the notches when rotating the extension tube relative to the first member, and the user feels a click to index the positioning feature.
