A window-based flash memory storage system and a management and an access method therefor are proposed. The ceramic filter assembly is produced by adhering with a ceramic seal layer outer surfaces of a plurality of filters, each of which is formed from a sintered porous ceramic body. , a second solvent which remains in a liquid state in a temperature range between 10\xb0 C. In this way, the fuel flow rate through the carburetor can be modified to obtain the optimal fuelair ratio for peak performance of the engine. The photogate is coupled through the diode photodetector and from there through a transfer gate to a corresponding readout register element. In formula, R1 and R2 each independently represent a hydrocarbon group having 1 to 6 carbon atoms, a halogenated alkyl group or a halogen atom, p and q each independently represent an integer of 0 to 4, and X represents a fluorine atom-containing divalent group.
