A liquid ejection device includes an ejection tube, a gripping tube, a liquid chamber, a connection channel, and a pulsed-flow generating section. The ejection tube is a tube for ejecting liquid. The gripping section is an instrument attached to the ejection tube and gripped by a user. The liquid chamber is provided on the outside of the gripping section. The connection channel connects the liquid chamber and the ejection tube. The pulsed-flow generating section is provided on the outside of the gripping section and generates a pulsed flow in the liquid in the liquid chamber.


An ultrasonic transducer element chip includes a substrate, a plurality of ultrasonic transducer elements and a plate-shaped member. The substrate includes a partition wall section defining a plurality of openings arranged in an array pattern. A wall thickness of the partition wall section is smaller than a wall height of partition wall section. Each of the ultrasonic transducer elements is provided in each of the openings. The plate-shaped member is fixed on a surface of the substrate opposite to a surface of the substrate on which the ultrasonic transducer elements are provided. The plate-shaped member covers at least one of the openings in a plan view seen along a thickness direction of the substrate.

A method of manufacturing a three-dimensionally formed object in which the three-dimensionally formed object is manufactured by laminating layers to forma laminate, includes: forming a constituent layer corresponding to a constituent region of the three-dimensionally formed object; forming a support layer which is in contact with the constituent layer and supports the constituent layer by ejecting a flowable composition including a resin from an ejecting portion in the form of liquid drops; solidifying the support layer; and heating the laminate which is formed in the formation of the constituent layer, the formation of the support layer, and the solidification of the support layer.


A density determination method includes a first process, a second process, and a third process. In the first process, ink is discharged onto a medium to print a plurality of colorimetric patches having mutually different densities on the medium so as to allow each of the colorimetric patches to include a base portion serving as a background of the each of the colorimetric patches and a low density portion forming a symbol and having a density lower than a density of the base portion. In the second process, images each associated with a corresponding one of the colorimetric patches are acquired. In the third process, a maximum printing density value for the medium is determined on the basis of a result of recognizing the symbol through each of the images, having been acquired in the second process.


Provided is a pretreatment agent for ink jet textile printing that can provide printed matters on fabric with high color-developing properties and less bleeding. The pretreatment agent includes at least water and (A) a multivalent metal ion and polymer fine particles, (B) a cationic polymer and polymer fine particles, or (C) cationic polymer fine particles.

An image reading apparatus includes a transport section that can transport original documents along a transport path, a reading section configured to read images of the original documents transported by the transport section, an output controller configured to output data of the original documents read by the reading section, a multi-sheet feed detection sensor configured to detect a multi-sheet feed of the original documents transported by the transport section, and an instruction section configured to issue an instruction to disable multi-sheet feed detection by the multi-sheet feed detection section. After a job for sequentially transporting a plurality of original documents to perform a reading operation for reading images is interrupted by multi-sheet feed detection performed by the multi-sheet feed detection sensor, and if the job is restarted in a disabling mode in which the multi-sheet detection is disabled in accordance with an instruction from the instruction section, the output controller outputs first data that is read in the reading operation before the interruption and second data that is read in the reading operation after the restart as a data stream that can be saved as a single file.

A printing apparatus includes a base unit (17) that can move in a moving direction (A) and a medium support unit (16) that supports a medium on which printing will be performed and moves in the moving direction (A) along with the base unit (17) by being attached to the base unit (17). When a position of the medium support unit (16) with respect to the base unit (17) during printing is defined as a base position, the medium support unit (16) is slidable with respect to the base unit (17) from the base position in the moving direction (A). By employing such a configuration, it is possible to suppress deterioration of work efficiency when setting a medium.
