There is provided a head including a chip 10 that has a semiconductor substrate 11, heating elements 12 disposed on the semiconductor substrate 11, coating layers 14 disposed on the semiconductor substrate 11 and having nozzles 14a arranged in regions above the respective heating elements 12, and individual channels 14b each communicating with the outside and the region above the corresponding heating element 12, wherein the semiconductor substrate 11 does not have a through hole communicating with each individual channel 14b; a ink feed member 21 having a common channel 21b, the ink feed member 21 being bonded to the chip 10 in such a manner that the common channel 21b communicates with the individual channels 14b; and a top 22 disposed on the chip 10 and the ink feed member 21 so as to seal the opening of the common channel 21b.
摘要:
A print head manufacturing method in which satisfactory precision can be obtained by simple processes are provided. Projecting objects having a predetermined shape are formed on a substrate, and a setting resin is applied on the substrate and is set. Then, the projecting objects are removed so that ink cells and nozzles are formed. The thickness of the setting resin is determined such that tip portions of the projecting objects project above the setting resin and ink cells can be formed.

The present invention provides a hybrid cell line producing monoclonal antibody to an acidic fibroblast growth factor (aFGF) protein. The hybridoma is established by fusing spleen cells from immunized mice with myeloma cells. The hybridomas are cultured as clones, and antibodies obtained from the individual clones are tested for their specificity for aFGF protein. Antibodies can be obtained from the culture growth medium or from ascitic fluid of mice bearing the hybridoma tumor. Diagnostic and therapeutic uses of the monoclonal antibody are also disclosed.

摘要:
A clamp 1 comprises a band 3, a buckle 5 having a support surface 18 against which a long component wound by the band is held, and a clip 6 extending from the buckle 5 and secured to, e.g., a body panel. The buckle 5 comprises a pawl 15 for engaging ratchet teeth 17 on the band, a first guide 25 and a second guide 26 forming an insertion passage 19 for guiding the band 3 and restraining the band 3 inside the insertion passage 19. The second guide 26 is formed in a shape by which the rear portion 30 of the insertion passage 19 including the outlet is parallel to the support surface 18, and the first guide 25 is formed in a shape by which the front portion 31 of the insertion passage 19 including the inlet is connected to the rear portion 30 at an acute angle of inclination 29 with respect to the rear portion 30.
摘要:
A polygonal coil having a substantially square shape is manufactured by winding a conductive wire in the diameter direction of the core on the core in an overlapping manner by the use of a winding jig in which a first collar portion and a second collar portion are disposed at both ends of a core so as to be opposed to each other and four rod-shaped protrusions are disposed on a surface of the first collar portion opposed to the second collar portion so as to protrude in a radial shape centered on an end of the core. As a result, it is possible to obtain a polygonal coil with high precision.
摘要:
A mutein of basic fibroblast growth factors (bFGF) possesses fibroblast growth promoting activity, growth stimulating activity of capillary endothelial cells and angiogenic activity, has high stability and is low toxicity. And therefore, the present mutein is advantageously used as a healing accelerator for burns etc., a therapeutic drug for thrombosis etc., and a cell cultivation promoter.
