A slit extending from a waste ink inlet position (indicated by a cross mark) in one direction is formed in a waste ink absorber of the waste ink tank. Thereby, the leakage of waste ink from a waste ink storage is avoidable by the improvement in the waste ink absorbing performance through a simple and inexpensive constitution.

An ink jet printing method prints an image on a printing medium by ejecting ink and printabilty improvement liquid containing a substance for improving printablity of the ink to the printing medium. At this time, ejection of the ink and ejection of the printability improvement liquid onto the printing medium are achieved such that the position where the printability improvement liquid is applied and the position where the ink is applied are different from each other, but partially overlap when the ejected printability improvement liquid comes into contact with the ejected ink on the printing medium.

A semi-closed type of breathing apparatus includes an air exhaling duct for guiding breathing air exhaled from a mouthpiece to a canister filled with a carbon dioxide remover, and an air inhaling duct for guiding the breathing air, from which carbon dioxide has been removed, to the mouthpiece. The air inhaling duct and the air exhaling duct are designed in a double-duct structure such that the air inhaling duct is surrounded by the air exhaling duct. That is, the ducts are formed in a single hose. Therefore, detachment of the breathing apparatus from a user is easily performed, the overall appearance of the apparatus is not marred, and the entire construction of the apparatus is simplified.

The present invention provides a liquid application device, an inkjet recording apparatus and a recording apparatus, which are capable of performing an adequate application initial operation according to the length of waiting time and power-off time, as well as a method of controlling the liquid application device. In the present invention, information on an end time of the previous processing for collecting liquid is read from a nonvolatile memory, current time information indicating the current time is obtained, and information on a lapse of time from the end time of the previous collection to a start time of the current application. Thereafter, the number of preliminary rotations R of an application roller is decided based on the information on the lapse of time with reference to a look-up table. Sequentially, the application roller is rotated by the decided number of preliminary rotations R to perform preprocessing operation.

In the case where a battery is reversely connected, unnecessary current-carrying to a glow plug is avoided.Power MOS type field effect transistors 1-1 to 1-n are provided according to a number of glow plugs 5-1 to 5-n to be connected in series between a vehicle battery and the glow plugs 5-1 to 5-n and can be controlled in conduction or non-conduction by a glow-plug control part 51, while a MOS type field effect transistor 2 for protection against reverse connection is provided in series connection between a battery-power joining terminal 3, to which a positive voltage of a vehicle battery is applied, and the ground to cause a reverse current to flow to a fuse 4 through the MOS type field effect transistor 2 at the time of reverse connection of a battery to melt the fuse 4 early whereby current-carrying to the glow plugs 5-1 to 5-n can be avoided.
摘要:
A printing apparatus can reduce degradation in print quality of a printed image, notably in a highlight portion or an intermediate gradation portion, in the case where the image is printed by forming dots of a plurality of sizes. Specifically, data causing larger and smaller cyan ink droplets, respectively, to be ejected is independently subjected to a conversion to n-value process. Thus, the data for larger ink droplets is present in a portion of printing data which corresponds to the highlight portion or intermediate gradation portion of the image. During printing, larger dots are formed in this area, thereby making it difficult to perceive possible stripes caused by the offset of the positions at which smaller droplets impact a sheet.
摘要:
An ink jet printing method uses an ink jet ejecting portion for ejecting ink on a printing material and a print quality improving liquid ejecting portion for ejecting print quality improving liquid on the printing material. The application mode of the print quality improving liquid is different depending on the printing mode in which a printing operation is carried out.
