Abstract: A semiconductor storage device includes a memory cell array and first and second circuits. The memory cell array is configured to store data in a non-volatile manner. The first circuit is configured to detect a first signal from an external device that is external to the semiconductor storage device. The first signal is required when the external device communicates with the semiconductor storage device in accordance with a first interface protocol, and not required when the external device communicates with the semiconductor storage device in accordance with a second interface protocol different from the first interface protocol. The second circuit is configured to generate a second signal in a first state when the first circuit detects the first signal and in a second state when the first circuit does not detect the first signal, the second state being different from the first state.

Abstract: A fuel vapor storage canister for an automotive vehicle, includes a casing formed thereinside with charge, purge and drain ports connected to a gas passage. First, second, third and fourth adsorption layers are disposed in the gas passage and arranged in order of first, second, third and forth adsorption layers from side of the charge port along a longitudinal direction of the gas passage. Each adsorption layer includes a fuel vapor adsorbent. Additionally, a first space section is formed between the first and second adsorption layers. A second space section is formed between the second and third adsorption sections. A third space section is formed between the third and fourth adsorption sections. Each space section has a width in the longitudinal direction of the gas passage.

Abstract: A fuel vapor treatment device for suppressing emission of fuel vapor from a fuel tank or the like of an automotive vehicle. The fuel vapor treatment device comprises a casing having a charge port connected to a fuel tank, a purge port connected to an intake section of an engine, and an atmospheric air port through which atmospheric air is introduced. Fuel vapor adsorbing material is filled in the casing. Additionally, an adsorbing material cartridge is disposed in a part of the casing and includes a cylindrical cartridge main body section having a cross-sectional area smaller than that of the casing. Fuel vapor adsorbing material is filled in the cartridge main body section. Air introduced from the atmospheric air port is flowable through the inside of the cartridge main body section to the fuel vapor adsorbing material in the casing.

Abstract: A fuel vapor treatment canister is described. The canister includes a casing having first and second end walls between which an inside space is formed. The first end wall has a first opening in communication with a fuel tank, and a second opening in communication with an air intake passage of an engine. The second end wall has a third opening in communication with the atmosphere. The inside space includes first and second chambers. The first chamber is located closer to the first end wall than the second chamber. A first fuel vapor adsorbing material is disposed in the first chamber. A second fuel vapor adsorbing material and a heat-accumulative material are disposed in the second chamber. The heat-accumulative material is larger in specific heat than the second fuel vapor adsorbing material.

Abstract: A fuel vapor treatment canister for controllably storing and releasing fuel vapor from a fuel tank and the like of an automotive vehicle. The fuel vapor treatment canister comprising a casing having first and second end walls between which an inside space is formed. The first end wall has a first opening in communication with a fuel tank, and a second opening in communication with an air intake passage of an engine. The second end wall has a third opening in communication with the atmosphere. The inside space includes first and second chambers. The first chamber is located closer to the first end wall than the second chamber. A partition wall is disposed to divide the inside space into the first and second chambers. The partition wall structure has an air permeability and a heat insulating ability higher than that of metal. A first fuel vapor adsorbing material is disposed in the first chamber. A second fuel vapor adsorbing material and a heat-accumulative material are disposed in the second chamber.

Abstract: A fuel vapor treatment device adapted to prevent evaporative emission from an automotive vehicle has a casing formed of a plastic and defines therein a space filled with a fuel vapor absorbent. An end wall is sealingly connected to a first end of the casing and provided with a first pipe through which fuel vapor is charged to the space, and a second pipe through which the fuel vapor within the space is purged. A cover plate is sealingly connected to a second end of the casing. A partition member is integral with the casing and disposed within the space of the casing to define first and second chambers. The partition member includes first and second partition walls that are parallel with each other and form a predetermined space therebetween. The partition member further includes a first lateral wall to connect first ends of the respective first and second partition walls, and a second lateral wall to connect second ends of the respective first and second partition walls.
