摘要:
An ink container for containing ink to be supplied to a recording head includes a main body, an ink absorbing material accommodated in the main body to contain the ink, a connecting portion relative to a supply tube of the recording head for supplying ink to the recording head, and a refilling connection at a position different from that of the connecting portion for refilling the ink. An ink absorption member is provided at the refilling connection portion, the ink absorption member having a bundle of fibers and a capillary force higher than that of the ink absorbing material. In an ink jet recording apparatus usable with such an ink container, a refilling mechanism is provided to fill the ink into the refilling connection portion, the refilling mechanism including an ink chamber for containing ink and an ink discharge member of porous material for press-contactedly supplying ink to the ink absorption member. In preferred embodiments, the ink absorption member has a capillary force higher than that of the ink absorbing material, and the ink discharge member has a density smaller than that of the ink absorption member.

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.

A wire harness manufacturing method prevents inadvertent deformation of thermoplastic material and separation of thermoplastic material. A predetermined part of an electric wire 91 is accommodated in a through hole of a tubular body formed by connection between a first and second nest members (123, 124) of a nozzle (12), by integrally connecting first and second case body members (121, 122) of the nozzle (12), with the predetermined part of the electric wire 91 therebetween. An approximately tubular covering member (92) covering the predetermined part of the electric wire (91) is molded integrally with the thermoplastic material, by discharging thermoplastic material plasticized by a material plasticizing unit (11) from thermoplastic material discharge orifices (1213) and (1223) in the nozzle (12) to the outer periphery of the electric wire (91), while moving the electric wire (91) and the nozzle (12) relatively to each other.

摘要:
The objective of the present invention is to provide a charged particle beam device such that a tip part can be effectually maintained in a clean state, while the frequency of valve body replacements is also reduced. To achieve the objective, a charged particle beam device is offered, comprising: a partition that is positioned between a charged particle source-side vacuum space and a specimen stage-side vacuum space, said partition further comprising an opening for a charged particle beam to pass through; a driver mechanism that moves a shutter member between a first location within the optical axis of the charged particle beam and a second location outside the optical axis of the charged particle beam; and a control device that controls the driver mechanism. The first location is a location wherein the shutter member is distanced from the partition, and the control device carries out a control that opens a valve between the specimen chamber and the exchange chamber when the shutter member is in a state of being located in the first location.
