A trash can assembly has a shell, a lid fitted over the top end of the shell, a pedal positioned adjacent the bottom end of the shell, a link assembly coupling the pedal and the lid, and a motion damper coupled to the link assembly for slowing the closing motion of the lid. A compaction blade in a compaction chamber adjacent the front end of the storage compartment is independently driven by a second hydraulic ram. A gate structure and a cap layer are formed, wherein the gate structure is disposed across parts of the fin-shaped structure and parts of the substrate, the cap layer is on the gate structure, and the cap layer includes a first cap layer on the gate structure and a second cap layer on the first cap layer. The anti-cancer antibodies can be conjugated to toxins, enzymes, radioactive compounds, and hematogenous cells. A control unit controls to generate an image corresponding the output voltage from the first type pixel in a moving image pickup mode, and to generate an image corresponding to the output voltages from the first and second type pixels in a still image pickup mode. The microspheres may be glass-coated microspheres, which are bound together by sintering the outer layers of glass together.
