An ink jet print head is provided which, during a suction-based recovery operation, can effectively remove air bubbles from the common ink path by producing an ink flow in the common ink path. In each of a plurality of bubble forming chambers where an element is installed to generate a thermal energy, there are provided a first ink path for leading ink directly from the ink supply port and a second ink path for leading ink from the common ink path formed on a far side of the array of the bubble forming chambers with respect to the ink supply port. The plurality of the first ink paths include those ink paths with less flow resistance than that of the second ink paths and those ink paths with higher flow resistance than that of the second ink paths.

Disclosed are a recording head cap to be mounted on a liquid-discharging recording head so as to protect an orifice-disposed face of the recording head, and a method and device for mounting the cap on the recording head. The recording head cap has a solid elastic member for pressing the orifice-disposed face when the cap is mounted on the recording head. The solid elastic member has an ultralow sponge hardness, and allows the orifice-disposed face of the recording head to be pressed with a substantially constant and uniform pressing force without being deformed, and to be thereby reliably protected during prolonged storage without causing ink leakage.

Provided is an inexpensive vehicular communication apparatus capable of transferring image data containing a record of an accident to a safe, external location, the apparatus being usable in an ordinary automotive vehicle. The apparatus includes an image sensing device, a data storage device for storing image data that has been captured by the image sensing device, a sensor for sensing impact, a portable-terminal holding device in which a portable terminal is capable of being placed, and an operation controller which, if impact has been sensed by the sensor, is for notifying a prescribed party via the portable terminal unless the portable terminal is removed from the portable-terminal holding device within a predetermined period of time.

Vehicular communication apparatus, communication method and computer-readable storage medium therefor

Disclosed is an innovative, compact and light liquid flow path opening/closing device that is simply structured, that can be appropriately employed for controlling the flow of ink along the ink path of an ink-jet printer, and that operationally is reliable. According to the present invention, an electromagnetic driven liquid flow path opening/closing device comprises a highly permeable drive shaft, a spring for impelling the drive shaft in one direction, a bobbin case within which the drive shaft inside a cylindrical chamber is positioned, a coil wound around the outer face of the bobbin case, a pair of highly permeable cases in which the bobbin case around which the coil is wound is stored, and inlet and outlet joints, communicating with the cylindrical chamber of the bobbin case wherein the drive shaft is positioned, wherein the joints are opened by impelling the drive shaft to counter the urging force exerted by the spring.

Liquid path opening/closing mechanism

There is disclosed a liquid supply apparatus which is disposed in an ink outlet of a flexible ink storage bag, having no pressure for supplying an ink, or disposed midway in an ink supply path, for supplying the ink to an ink jet head, and which is small in size, little in power consumption and simple in mechanism. A liquid pressurizing supply apparatus is driven in response to an alternating or pulse electric signal, and comprises a high-permeability driving shaft, a spring for urging the driving shaft in one direction, a bobbin case in which the driving shaft is disposed in a cylindrical chamber, a winding coil wound around an outer peripheral surface of the bobbin case, a pair of high-permeability case members in which the bobbin case with the winding coil wound therearound is contained, and a containing recess portion is formed by a sheet metal drawing process, inlet and outlet joints connected to the cylindrical chamber of the bobbin case, and a ball check valve for preventing ink back-flow.

In a print head which can be mounted in a printer and which has a first ejection portion to eject an ink and a second ejection portion to eject a print performance improving liquid to aggregate or make insoluble the ejected ink, the storage method effectively prevents the mixing of the ink and the print performance improving liquid if one or both of these liquids should leak before the print head is mounted in the printer. The seal member having an opening and adapted to seal the first and second ejection portions so that its opening is located between these ejection portions is removably bonded to the print head. This arrangement closes the ejection portions with the protective tape, preventing leakage of the ink and the print performance improving liquid. If one or both of these liquids should leak, the liquid seeping toward the other ejection portion by capillary action generated at the joint portion between the protective tape and the orifice plate surface can be blocked by the opening of the protective tape that nullifies the capillary action.

Ink-jet cartridge and method of storing print head

A packaging structure of the present invention is provided for an ink tank having an ink supply port and an atmosphere communicating port. It has a seal member for sealing the ink supply port, a seal member for sealing the atmosphere communicating port, and an integrated covering member for integrally covering the ink tank having at least these seal members. A partial breakage of the covering member leads to open the atmosphere communicating port at first. Thus, the combination of the packaging structure and the ink tank is constructed so as to open the atmosphere communicating port at first with reliability. It is functionally required at the time of pulling out the ink tank from the package and also at the time of physical distribution without causing an ink leakage, regardless of the shape of the ink tank.
