摘要:
An atmosphere-vented valve (a pressure relief section) is opened in a predetermined amount so as to reduce an inside pressure of a canister to a predetermined negative pressure (S14) while preventing an inside pressure in a fuel tank from becoming an excessively negative pressure by closing a charge passageway opening and closing valve (S18), and purging is controlled while the canister inside pressure is being reduced, whereby from a similar principle to that of vacuum distillation, the release of vaporized fuel from an absorbent is promoted so as not only to increase the purge efficiency but also to prevent the application of an unnecessary stress to the fuel tank.

An evaporated fuel treatment apparatus is provided for reducing a refilling time, ensuring satisfactory adsorption/desorption performance for an evaporated fuel, and reducing the manufacturing cost through a simplified structure. The evaporated fuel treatment apparatus comprises a casing having formed therein a first chamber in communication with the fuel tank, a second chamber in communication with the first chamber, and a third chamber in communication with the second chamber and the atmosphere. Active carbons are contained in the first chamber and second chamber for adsorbing fuel components in an evaporated fuel introduced from the fuel tank. An adsorbent is contained in the third sub-chamber for adsorbing fuel components in the evaporated fuel introduced from the second chamber. The adsorbent has an air-flow resistance which is set smaller than that of the active carbons.

A fuel vapor processing apparatus is provided for realizing a high desorption performance and a high flexibility in layout resulting from a compact structure including a filter. The processing apparatus comprises a casing formed with a fuel vapor introducing port communicating with the fuel tank, and a fuel vapor discharge port communicating with the intake pipe. A partition is arranged in the casing for defining inside thereof a filter chamber which communicates with an air introducing port for introducing desorbing air from the atmosphere. The partition partitions the casing into a first chamber and a second chamber with a spacing interposed therebetween. The first and second chambers communicate with each other, and also communicate with the filter chamber, the fuel vapor introducing port, and the fuel vapor discharge port. The processing apparatus also comprises a filter contained in the filter chamber for filtering the desorbing air introduced from the air introducing port, and an adsorbent material filled in the first and second chambers for adsorbing the fuel vapor introduced from the fuel vapor introducing port.

The concentration of a hydrocarbon gas in a gas discharged from a drain port is detected by a break-through gas concentration sensor provided in a discharge pipe connected to the drain port. The entire amount of the hydrocarbon gas discharged from the drain port as a result of breaking-through of an adsorbent layer is collected by a break-through gas collecting means, and the entire amount of the hydrocarbon gas collected by the break-through gas collecting means is detected. Thus, in measuring the adsorbing ability of a canister, the concentration of the hydrocarbon discharged from the canister by the breaking-through can be detected with the passage of time and in a stable manner, whereby a measurement value of an excellent accuracy can be provided by a single measurement.

A production method of a semiconductor element having a channel includes forming a resist pattern film on a thin film formed on a substrate, and pattering the thin film by etching. The production method also includes forming a second resist pattern film by applying a fluid resist material inside a channel groove after channel etching or inside a resist groove formed above a channel region before channel etching. The production method may also include forming a gate electrode, a gate insulating film, a semiconductor film, and a conductive film on an insulating substrate. The method may include applying the fluid resist material inside the channel groove, thereby forming the second resist pattern film, and patterning the semiconductor film using at least the second resist pattern film.

摘要:
A connecting terminal has a configuration in which a plurality of parts of a first line (2) and respective corresponding plurality of parts of a second line (6) are connected to each other by a transparent conductive thin film (10). In a connecting terminal part, the plurality of parts of the first line (2) and the respective corresponding plurality of parts of the second line (6) are connected to each other in parallel. With the configuration, it is possible to greatly reduce a risk of disconnection. It is therefore possible to prevent disconnection from being caused by corrosion in the connecting terminal part of a display apparatus etc.
