摘要： An ink jet recording head has a plurality of discharge energy generating devices for discharging recording liquid, while being provided with a recording element base plate arranged on the face opposite to the surface where the devices are arranged, having a plurality of recording liquid supply ports for supplying recording liquid to the devices, as well as with a supporting member that holds and fixes the recording element base plate. For the supporting member, a plurality of recording liquid supply paths are arranged to supply recording liquid to each of the supply ports of the recording element base plate, respectively, and then, the flow path width of each supply flow path is formed to be smaller than the opening width of inlet portion of each supply port. Further, the steps to be created between the supply flow path and the supply port is buried by the bonding agent forced out from the bonding face of the recording element base plate and the supporting member. With the structure thus arranged, the ink jet recording head is capable of optimizing the discharge characteristics of recording liquid and the supply characteristics thereof, as well as the positioning precision of a recording element base plate to a supporting member.

摘要： The present invention provides a liquid housing container that enables an increase in the channel cross section of a connection portion of a liquid channel that allows a liquid housing chamber to communicate with an exterior, allowing pressure loss to be minimized. A supply needle 107 is pushed into a liquid housing container to move, to an open position, a valve 102A. With the valve 102A remaining in the open position, the supply needle 107 is pushed back and held separate from the valve 102A. Subsequently, the supply needle 107 is pushed into the liquid container again to move the valve 102A to a closed position. Even when the supply needle 107 is removed from the liquid housing container, the valve 102A is held in the closed position.

摘要： A liquid discharge apparatus for producing a probe carrier, having a configuration capable of supplying a discharge unit with plural probe solutions without increasing the dimensions of the apparatus, as well as a method and apparatus for producing the probe carrier utilizing such liquid discharge apparatus. The arrangement pitch of the supply openings to liquid holding portions from plural liquid discharging portions (which are provided in the liquid discharge apparatus and respectively correspond to the plural probes) is set to be larger than the arrangement pitch of nozzle openings, thereby increasing the freedom in designing the position and capacity of the liquid holding portions for holding the probe solutions.

摘要： Precision of detecting existence/non-existence of a liquid container and a liquid level in the container is improved even if the detection is performed by a single sensor, or even if the S/N ratio of the detection is low, the detected results can be discriminated from one another. For this, a concave polyhedron is provided in the center of the bottom surface of an optical prism in order to reduce the amount of light reflected on the bottom surface of the optical prism and returned to a photoreceptor. Moreover, a reflection curved surface having a quadratic surface e.g. spherical surface or paraboloid, is provided on the bottom surface of an ink tank, for reflecting light emitted by an optical unit consisting of a light emission device and a photoreceptor. By virtue of this, even in a case where an arrangement angle or position of the optical unit is deviated to some extent, sufficient amount of light for the photoreceptor can be received, making it possible to accurately detect existence/non-existence of ink and/or existence/non-existence of an ink tank.
摘要翻译：即使通过单个传感器执行检测，即使检测到的S / N比低，检测出液体容器的存在/不存在以及容器中的液面的精度也提高，检测结果可以彼此歧视。为此，在光学棱镜的底面的中心设有凹面多面体，以减少在光学棱镜的底面上反射的光并返回感光体。此外，具有二次表面的反射曲面，例如，球形表面或抛物面，设置在墨水罐的底表面上，用于反射由发光装置和感光体组成的光学单元发出的光。由此，即使在光学单元的配置角度或位置偏离一定程度的情况下，也可以接收足够量的感光体的光量，能够精确地检测墨水的存在/不存在以及 /或墨水罐的存在/不存在。

摘要： A container for containing liquid to be ejected. The container includes a negative pressure producing member accommodating chamber for accommodating a negative pressure producing member. The negative pressure producing member accommodating chamber is provided with an air vent for fluid communication with ambience and a liquid supply portion for supplying the liquid to a liquid ejecting head having ejection outlets. The container also includes a liquid containing chamber which is substantially hermetically sealed except for a fluid communication path through which the liquid containing chamber is in fluid communication with the negative pressure producing member accommodating chamber. A partition is provided for separating the negative pressure producing member accommodating chamber and the liquid containing chamber. The partition is provided with an ambience introduction path for introducing the ambience into the liquid containing chamber from the negative pressure producing member accommodating chamber. The ambience introduction path forms a capillary force generating portion. The capillary force which is produced by the capillary force generating portion satisfies a relationship between that capillary force and potential head differences, head losses, and other capillary forces in the container.
