To provide a waste ink absorbing tank, capable, even in the case of utilizing an ink of a high coagulating property, of causing a waste ink absorbent member to efficiently absorb such ink. A waste ink absorbent member has a hole portion corresponding to an introducing position of the waste ink, and the hole portion is opened on a lateral face of the absorbent member. The waste ink, introduced into the hole portion moves in one direction toward the waste ink absorbent member and absorbed therein.

Waste ink absorbent member, and waste ink container and ink jet recording apparatus equipped with waste ink absorbent member

The invention relates to a surface-modified inorganic pigment which has an inorganic pigment having acid function and an amorphous body located on the surface of the inorganic pigment having acid function and formed by at least a divalent or higher-valent metal and an anion component in a state where the inorganic pigment and the amorphous body do not chemically bond to each other, and which does not exhibit acid function.

Surface-modified inorganic pigment, colored surface-modified inorganic pigment, recording medium and production processes thereof, and image forming method and recorded image

The present invention relates to a pigment dispersion having an inorganic pigment dispersed therein, characterized in that a metal compound adheres to the inorganic pigment and a metal ion concentration of the metal compound in the pigment dispersion does not exceed 0.05 mol/L.

Pigment dispersion and inkjet recording medium using the same

A liquid loading method, a liquid container and a head cartridge are provided, which allow the liquid container to be appropriately loaded with liquid such that a stirring member provided in the liquid container fully fulfills its function. For this end, an infusion needle is inserted from the outside of the ink cartridge into the ink storage chamber comprising a swinging member for stirring ink, so that the ink is loaded into the ink storage chamber through the infusion needle.

Method for loading liquid, liquid container and head cartridge

At least one exemplary embodiment is directed to a laser cutting method where a laser beam is condensed at internal points inside a substrate forming processing regions, and where the laser is swept along a cutting line, where the cutting line is associated with a recess on the substrate and where the recess can be formed contemporaneously with the formation of the processing regions.

Laser cutting method

A laser cutting apparatus and a laser cutting method are provided which are adapted to concentrate laser light into a silicon substrate to produce a plurality of internal cracks. A light concentrating position, to which laser beams included in the laser light are concentrated, is temporally and spatially displaced to appropriately change lengths of the cracks according to positions in a direction of depth of the substrate. Consequently, the lengths of the internal cracks are controlled to surely lead a crack opening, the starting point of which is the internal crack formed by laser processing, to a predetermined cutting line on a surface of the substrate.

Laser cutting apparatus and laser cutting method

An aqueous ink comprises water, a water-insoluble coloring material, and plurality of water-soluble organic solvents and the plurality of water-soluble organic solvents including a good medium or good mediums for the water-insoluble coloring material and a poor medium or poor mediums for the water-insoluble coloring material. The ratio of the content of the poor medium and the content of the good medium is in a specific range. A water-soluble organic solvent showing the maximum Ka value out of respective Ka values of the plurality of water-soluble organic solvents is the poor medium. When the aqueous ink is in contact with a specific reaction liquid, the dissolution state or dispersed state of the water-insoluble coloring material in the ink is made unstable. As a result, an image which has a sufficiently large area factor even with a small amount of ink droplets and is excellent in image density, bleeding resistance, and fixability can be obtained. In addition, the aqueous ink is excellent in storage stability.

Aqueous ink, aqueous ink set, ink cartridge, ink-jet recording apparatus, ink-jet recording method, and image-forming method

A mat type recording medium for ink jet printing is provided which exhibits optimum printability no matter which of dye ink and pigment ink may be used in printing. The recording medium, which is for recording with use of water-based ink containing an ink colorant, comprises a paper base and an ink receptive layer formed on a surface of the paper base, the ink receptive layer comprising a porous layer containing an inorganic pigment and also containing a substance reactive with the ink colorant.

Recording medium for water-based ink and method for determining ink absorbing characteristic thereof

There is disclosed a solid semiconductor element which very efficiently detects information about a liquid and bidirectionally exchanges the information with the outside. The solid semiconductor element is disposed in a liquid container, and includes at least energy converting unit, information acquiring unit, and information communicating unit. The energy converting unit converts an electromotive force from the outside to a power, and operates the information acquiring unit and information communicating unit. The information acquiring unit acquires the information about the liquid in which the solid semiconductor element is disposed from the liquid, and the information communicating unit transmits the information acquired by the information acquiring unit to the outside.

Solid semiconductor element, ink tank, ink jet recording apparatus provided with ink tank, liquid information acquiring method and liquid physical property change discriminating method

A laser processing apparatus, in accordance with at least one exemplary embodiment, is configured to contemporaneously perform the functions of observing a surface of a substrate and concentrating laser light to a given position inside the substrate. The laser processing apparatus can include an optical system having an afocal optical subsystem configured to concentrate laser light inside the substrate. Adjustment of the position of a laser light concentrating point can be achieved independent of adjustment of a focal point by the automatic focusing mechanism to observe the surface of the substrate irradiated with laser light.

Laser processing apparatus and laser processing method

At least one exemplary embodiment is directed to a laser processing apparatus that can use the shape of a plurality of reflected light fluxes to adjust the position of workpiece relative to an optical system, where the laser processing apparatus facilitates both the viewing of the workpiece and a focusing of a processing laser into the workpiece.

Automatic focusing apparatus, laser processing apparatus, and laser cutting apparatus

A portable terminal carried and owned by each user is provided with a display screen, a communication unit, a memory storing personal information about each user, and an input/output device such as an inhaler. A database that communicates with each portable terminal is provided with a personal information storage unit storing the personal information about each user carrying the portable terminal, a medical information storage unit storing information about a medical facility, a drugstore, a medicine, and the input/output device, and a communication unit for communicating with each portable terminal. In the database, the user of the portable terminal is identified by collating the part of the information transmitted from the communication unit with information stored in the personal information storage unit. When a specific signal is transmitted from the communication unit, communication is performed with a medical facility while information, of the information stored in the medicine information storage unit, which is necessary for the user is provided for the portable terminal as an emergency measure.
