One aspect of the disclosure is directed to a heat sink assembly for dissipating heat from an electronic component. When a motion-image record mode is selected by the record-mode selector switch and the shutter button is pressed, camera signals of a plurality of screens are outputted from an image sensor. The band plates contact opposite surfaces of the protrusion. An error detection circuit 1026 and error correction circuit 1028 detect and correct random errors in the delayed value and supplies an error-checked delayed value to the comparator 1024. Further, the invention includes methods utilizing a microarray to measure the glycan level of a protein.
