A toy vehicle includes a main body assembly supported for movement on wheels and having opposing right and left lateral sides, opposing front and rear ends, and opposing top and bottom sides extending between the lateral sides and the ends. The magnetic random access memory thus-structured radiates heat generated in the magnetic recording layer by using the heat sink structure, suppressing the temperature increase caused by the write current flown in the in-plane direction. A method for pumping a fluid from a low-pressure fluid source to a high-pressure fluid outlet and a method for storing or transporting a fluid are also provided, wherein the fluid comprises a VOC. Connectors such as board-to-board connectors may be used to couple printed circuit substrates together. In the present invention, a manufacturing method comprises the steps of forming a plurality of IT-CCDs on a surface of a semiconductor substrate, bonding a translucent member to the surface of the semiconductor substrate in order to have a gap opposite to each light receiving region of the IT-CCD, and isolating a bonded member obtained at the bonding step for each of the IT-CCDs.
