摘要： When detection of an abnormality in a fuel vapor treating system is executed, a vapor zone including a fuel tank and a canister is sealed. The sealed vapor zone is pressurized. Whether fuel vapor is leaking from the vapor zone is determined based on the pressure in the sealed vapor zone. A canister valve selectively connects a canister with and disconnects the canister from the atmosphere. During the abnormality detecting procedure, an electronic control unit (ECU) shuts the canister valve. After the abnormality detecting procedure is ended, the ECU sends a control signal having a predetermined frequency to the canister valve, thereby gradually increasing the opening size of the canister valve. Accordingly, the pressure in the vapor zone is gradually lowered to the atmospheric pressure. This prevents fuel vapor adsorbed by the canister from being released to the atmosphere.

摘要翻译： 当执行燃料蒸汽处理系统的异常检测时，密封包括燃料箱和罐的蒸气区。 密封的蒸气区被加压。 燃料蒸汽是否从蒸汽区泄漏是基于密封蒸气区中的压力来确定的。 罐阀选择性地将罐与大气连接并将罐与大气隔离。 在异常检测过程中，电子控制单元（ECU）关闭罐阀。 在异常检测步骤结束之后，ECU向罐阀发送具有预定频率的控制信号，从而逐渐增加罐阀的开度。 因此，蒸汽区中的压力逐渐降低至大气压。 这防止了由罐吸附的燃料蒸气被释放到大气中。

摘要： A cleaning apparatus includes a cleaning cloth, supply shaft, take-up shaft, detector, projections, proximity switch, and catching detection unit. The cleaning cloth is pressed against a rotary member and cleans an outer surface of the rotary member. The cleaning web before cleaning is wound around the supply shaft. The supply shaft rotates in accordance with supply operation of the cleaning cloth to the outer surface of the rotary member. The take-up shaft is rotatably driven to take up the cleaning cloth supplied from the supply shaft to the outer surface of the rotary member. The detector, projections, and proximity switch output a signal corresponding to a rotational speed of the supply shaft. The catching detection unit detects that the cleaning cloth is caught in the rotary member on the basis of a state of the signal output from the detector, projections, and proximity switch. A method of detecting catching of the cleaning web in the cleaning apparatus is also disclosed.

摘要： An ink jet recorder comprises a carriage for holding an ink jet head, capable of sweeping across a recording medium, an ink cartridge for supplying ink to the head, and a detector for detecting whether the fluid level of the ink inside the ink cartridge is at a prescribed level. At least two detection operations are performed by the detector. If two of those detection operations indicate an ink fluid level short of the prescribed level, ink cartridge replacement is displayed on a display. Erroneous ink level judgments can thus be held to a minimum even when the ink forms waves inside the ink cartridge due to the movement of the carriage in the sweep direction.

摘要： The electromagnetic valve has a valve body capable to open and close a fluid communication path, first and second springs opposing to each other and biasing the valve body. Biasing forces of the first and second spring toward the valve body are balanced with each other so as to have valve body open the communication path. When a coil is energized, a moving member is driven so as to have the valve body move against the biasing force of the first spring during a first moving stroke so that an elastic energy may be stored in the first spring. When the coil is de-energized, the valve body is moved back by the first spring not only during the first moving stroke but also during a second moving stroke to absorb the elastic energy stored in the first spring by the second spring. There is an enough space where the moving member may move back during the second moving stroke so as not to hit any part.

摘要： A multiple value image input device receives image data expressed in pixels with each pixel expressed in one density gradation level or shading. A method and device for correcting image data read by an image scanner has a density reference plate with a number indicating segments with known density gradation levels. The image scanner reads the density indicating segments and compares the actually read density gradation level with the known density gradation level. One or more density indicating segments is selected to be scanned. The selection may be based upon the image data to be read.
