摘要:
An ink absorber is housed inside a housing of an ink tank and is capable of retaining ink. The ink absorber has an outer surface equal to or corresponding to a shape of an internal surface of the housing and is made of a fiber material obtained by compressing a fiber body and thermally molding at least a surface thereof. An ink tank is comprised of the ink absorber and the housing. An ink jet cartridge is comprised of the ink tank and a print head. The ink absorber has an outer surface equal to or corresponding to a shape of an internal surface of the housing before being inserted into the housing. The ink absorber comprises a fiber material, and is formed by compressing a fiber body and thermally molding at least a surface thereof.

Provided is a liquid recording head in which a protective layer having resistance to liquid and an adhesiveness improving film are disposed on a second surface opposite to a first surface of a silicon substrate. The first surface and the second surface have a plane direction. The protective layer is disposed in a peripheral region of an opening of a liquid supply port. A liquid ejection chip is bonded to a head substrate with an adhesive so that the liquid supply port communicates to a liquid introduction port on a side of the second surface of the silicon substrate.

A liquid recording head includes a protective layer having resistance to liquid and an adhesiveness improving film disposed on a second surface of a silicon substrate, opposite to a first surface. The first surface and the second surface have a plane direction (100). The protective layer is disposed in a peripheral region of an opening of a liquid supply port. A liquid ejection chip is bonded to a head substrate with an adhesive so that the liquid supply port communicates with a liquid introduction port on a side of the second surface of the silicon substrate.

In order to avoid damages or deformations to ejection energy generating elements formed on a substrate or grooved plate, when the substrate and the grooved plate are joined, a liquid ejection head for an image forming apparatus includes a substrate having electro-thermal energy conversion elements thereon, a grooved plate having grooves formed at positions corresponding to the electro-thermal energy conversion elements, ejection ports communicating with the respective grooves, and liquid paths communicating with the ejection ports. At least two protrusions are formed on the substrate apart from each other and corresponding engaging recessed portions are formed on the grooved plate for engaging the protrusions. A height from the surface of the substrate to upper ends of the protrusions is set higher than a height from the surface of the substrate to upper ends of the electro-thermal energy conversion elements or other micro processed portions.

An ink jet head comprises a head substrate provided with a plurality of ink paths, pressure generating elements each arranged for each of the paths; and an orifice plate provided with ink discharge openings each communicated with each of the ink paths. Then, the bonding surface side of the orifice plate to the substrate is provided at least with the surface treatment. The orifice plate is formed by fluororesin or resin containing fluorine. With the structure thus arranged, it becomes possible to bond the orifice plate having ink repellency to the head substrate firmly and assuredly, while enabling the ink jet head thus manufactured to maintain a good ink repellency for a long time.

An optical disc recording device, wherein, during an OPC process addressing a write-once optical disc provided with only one or two recording layers, a recording power value of an optical pickup is changed within a range from (100−A) % of a reference recording power value to (100+B) % of the reference recording power value, and wherein, during an OPC process addressing a write-once optical disc provided with three or more recording layers of the same type as the aforementioned write-once optical disc, the recording power value of the optical pickup is changed within a range from (100−C) % of a reference recording power value to (100+D) % of the reference recording power value, D being set to be less than B.
摘要:
To form an inkjet printing head which is not deteriorated in printing quality or broken in production processes, a rib capable of being displaced upon receiving an influence of stress resulting from a sealant is installed at a position opposing the long side face of a printing element substrate, and the sealant is used to seal between the ribs and the printing element substrate.

An optical disk device includes a test recording portion, a power control portion, a recording portion and a power correction portion. The power control portion determines a first recording power to record recording information to the optical disk based on test information recorded by the test recording portion. The power correction portion calculates a first average of modulation of the recording information recorded on a first track of the optical disk at the first recording power and a second average of modulation of the recording information recorded on a second track of the optical disk at the first recording power. The power correction portion increases the first recording power to a second recording power when the second average of the modulation drops below a first threshold value that is preset and drops below a second threshold value that is calculated based on the first average of modulation.

To make the most of characteristics of a device and a person and allow efficient handling even if a workpiece to be handled is changed when the device and the person perform operations in a shared area. The device 6 and the person 7 perform an assembling operation of a component to be assembled 3 to a vehicle body 2. When the assembling operation is classified into operations such as ejection of the component, conveyance, positioning, and mounting/fastening, a pattern 1 in which all the operations are performed by the device 6, and patterns 2 to 4 in which part of the operations are performed by only the person 7 or by the person and the device in collaboration and the remaining operations are performed by the device 6 are preset, and the patterns are switched according to the type of the component to be assembled 3 so as to make the most of high power of the device 6 and good judgment of the person 7 even if the type of the component to be assembled 3 is changed.
