A closed tank system includes: a fuel tank; a canister adapted to adsorb evaporative fuel generated in the fuel tank; a fill-up limiting valve provided inside the fuel tank so as to be communicated with the evaporative fuel discharge passage and adapted to operate to close the evaporative fuel discharge passage when a fuel level reaches a predetermined full tank liquid level; a shut-off valve adapted to operate to open or close the evaporative fuel discharge passage; a fuel remaining amount sensor adapted to detect a remaining amount of fuel; and a hardware processor that causes a control section to carry out control for allowing the shut-off valve to be opened or closed. The hardware processor causes the control section to inhibit the control for allowing the shut-off valve to be opened when an engine is in operation and the detected remaining amount of fuel exceeds a predetermined threshold.

Closed tank system

A fuel shutoff valve is attached to the upper portion of a fuel tank and shuts off the communication between the inside of the fuel tank and a canister by opening and closing a vapor passage for communicating between the fuel tank and the canister. The fuel shutoff valve is configured with a first valve mechanism having a coil disposed on the inner periphery of a cylindrical valve chamber and a movable core, which enables to communicate between the fuel tank and the canister by lowering the level of the movable core, and a second valve mechanism which enables to communicate between the fuel tank and the outside thereof by shifting the level of the valve body which is disposed inside the movable core due to the pressure from the inside of the fuel tank or the outside thereof.

Fuel shutoff valve

An evaporated-fuel processing apparatus including: a sealing valve which is arranged in a communication path between the atmosphere and a fuel tank mounted on a vehicle having an internal combustion engine, and shuts an internal space of the fuel tank off from the atmosphere; an open/close member which covers a fuel filling port of the fuel tank; a refueling-intention-information acquisition unit which acquires information indicating an intention of refueling; and a control unit which issues an opening command for opening the sealing valve when the refueling-intention-information acquisition unit acquires the information indicating an intention of refueling, and allows the open/close member to open when a time elapsed from the moment at which the opening command is issued exceeds a first predetermined time.

Evaporated-fuel processing apparatus

A wave suppression structure for a fuel tank is provided in which a wave suppression member () disposed in the interior of a tank main body of the fuel tank is formed from a basket-shaped container () and cylindrical porous members (), the basket-shaped container () being formed from two members, first and second half bodies (L,R), two of the porous members () being supported in the interior of each of the first and second half bodies (L,R), wherein the wave supporting member () is supported on a fuel suction pipe () by joining the first and second half bodies (L,R) of the basket-shaped container () so as to sandwich a fuel suction pipe () between a through hole () thereof. This enables attachment of the wave suppression member () to the fuel suction pipe () to be completed without carrying out a cumbersome operation of inserting the fuel suction pipe () through the through hole () of the basket-shaped container () or the interior of the porous member (), thereby greatly improving the ease of attachment.

Wave suppression structure for fuel tank

Provided is a fuel tank system wherein the liquid levels of fuel in two fuel storage portions can be equally maintained, and the fuel amount in each fuel tank can be estimated with a high degree of accuracy. The fuel tank system is provided with a fuel tank in which a main tank portion and a subsidiary tank portion are formed; a siphon tube which extends from the main tank portion to the subsidiary tank portion, to transfer fuel from one tank portion to the other tank portion; and an electronic control unit (ECU) for determining whether or not the fuel is transferred via the siphon tube (in the transfer state). The ECU determines that the fuel is in the transfer state when the change rate of a sender signal is equal to or less than a predetermined threshold value (VF_th).

Fuel tank system

A fuel introducing member is connected to an opening end of a siphon pipe forming a fuel tank. The fuel introducing member has an opening for introducing fuel within the tank, and the opening is formed in the upper surface of a cover section. A lid body is pivotably mounted to the upper surface. When the opening is above the level of fuel, the lid body closes the opening by the weight of the lid body, and when the opening is below the level of the fuel, the lid body floats in the fuel to open the opening. The opening is located below the upper end of the inner diameter of the opening end of the siphon pipe.

Fuel tank

An improved fuel tank is disclosed. In the fuel tank, a shock-absorbing member comprising a plurality of foam members is mounted to an in-tank functional component provided inside a resin fuel tank body. When the fuel inside the tank sloshes up and down, the fuel strikes the shock-absorbing member, causing the force of the waves to be dispersed, and reducing the fuel sloshing sound created by the sloshing of the fuel.

A magnetic recording medium substrate has a polyester film having metallic oxide-containing layers (layers M) formed on both the surfaces, one layer on each surface, the layers M having a thickness of 50 to 200 nm each, characterized in that the magnetic recording medium substrate has a total light transmittance of 0 to 75% and a surface resistivity of 1&#xd7;10to 1&#xd7;10&#x3a9; on each surface.

Support for magnetic recording medium, and magnetic recording medium

A radio wave absorbing coating composition that exhibits an excellent absorption performance of radio waves in 40 MHz to 3 GHz frequency band is provided. The radio wave absorbing coating composition contains metal powder that is made up of a martensitic Fe&#x2014;Cr&#x2014;Ni alloy powder and/or a martensitic Fe&#x2014;Ni alloy powder, carbon powder, resin, and solvent.
