    摘要: A charging control circuit according to an embodiment of the present invention includes a detecting circuit and a charging transistor control unit for controlling a charging transistor supplying a first current, a current source for supplying a second current, and a current source control unit for controlling the current source. For example, if a secondary battery is charged using an adaptor endowed with a current-limiting function, during a constant-current charging period in which a charging voltage of the secondary battery reaches 3.2 V to 4.2 V, the secondary battery is charged with the first current I1, and during a constant-voltage charging period after the voltage reaches 4.2 V, the secondary battery is charged with the first charging current and the second charging current.

    摘要: In the semiconductor device according to the invention, a tubular storage node is formed, then slanting rotation implantation of impurity phosphorus ions is executed for changing the phosphorus concentration and the etching rate at the thermal phosphoric acid treatment time is changed for roughening the surface under good control. Since the surface roughening does not extend to the center of the film of the storage node, the strength of the storage node can be held sufficient. Therefore, the capacitance can be increased.

    摘要: A fuel evaporative emission treatment system includes a canister which has an evaporative fuel introduction part arranged for communication with a fuel tank, an evaporative fuel emission part arranged for communication with an intake system of an engine, and a vent part arranged for communication with the atmosphere, and which absorbs the evaporative fuel. The fuel evaporative emission treatment system includes a vent pipe having a first passage communicating to the vent part of the canister and to the atmosphere, a first solenoid valve for opening and closing the first passage, an air filter for cleaning atmospheric air flowing thereinto, the filter being provided on the first passage on the side remote from the canister with respect to the first solenoid valve, and a one-way valve or lead valve which defines a second passage communicating to the vent part of the canister. The valve is opened at fueling. The evaporative fuel generated in the fuel tank upon fueling contains a fuel component which is eliminated by the canister and emitted into the atmosphere through the second passage. As a result, the fueling performance will not deteriorate even if the air filter is provided.

    摘要: A fuel evaporative emission treatment system installed in an engine fuel system has a canister for adsorbing evaporative fuel, a vent hose connecting a fuel tank and the canister, and a vent circulation hose connecting the vent hose and a filler neck of the fuel tank, and the sectional areas of the vent hose and vent circulation hose are set so that the ratio thereof may be a proper value. The negative pressure produced in the filler neck due to aspiration induced by refueling is canceled out by the pressure of fuel gas circulated to the filler neck through the vent circulation hose, whereby the internal pressure of the filler neck is controlled to a value appropriately smaller than the atmospheric pressure. Thus, inflow of the outside air into the filler neck, and thus generation of evaporative fuel gas, can be suppressed, and also the outflow of evaporative fuel gas from the filler neck is suppressed.
