摘要:
A liquid droplet ejection apparatus in which a function liquid droplet is selectively ejected toward a workpiece while carrying out a relative movement between a function liquid droplet ejection head and the workpiece is made up of: a plurality of function liquid droplet ejection heads; a carriage for mounting thereon the plurality of function liquid droplet ejection heads; a head stocker for stocking the plurality of function liquid droplet ejection heads; and a head transfer mechanism for transferring each of the plurality of function liquid droplet ejection heads between the carriage and the head stocker. The function liquid droplet ejection heads are automatically replaced, so that the liquid droplet ejection apparatus can perform the workpiece processing efficiently.

There is provided a through structure of connecting lines extending through a wall of a gastight chamber. The through structure of the connecting lines is capable of positively sealing between the wall and the connecting lines extending therethrough. The through structure enables the connecting lines to extend through the wall of the gastight chamber for connecting a work processing apparatus contained in the gastight chamber and accessories for the work processing apparatus. The through structure comprises a through sleeve extending through the wall, with the connecting lines extending therethrough, a first seal member filled in the through sleeve for sealing between the through sleeve and the connecting lines, and a second seal member for sealing between the through sleeve and the wall.

摘要:
To provide a liquid droplet ejection method which can detect abnormality of a nozzle, an ejection head including a plurality of nozzles has, for the respective nozzles, a camera unit that images from the inside of a nozzle to its peripheral portion. A captured image processing unit converts the captured image into an image which can recognize at least one of a state of a meniscus inside the nozzle, the shape of a nozzle opening and states of surface films formed inside and outside the nozzle, and sends the converted image to a comparison determination unit. The comparison determination unit compares the converted image with a reference image which is previously stored in a determination condition storing unit. As a result, for an objective nozzle, the quality (nozzle abnormality) of ejection performance is determined.

A narrow gap welding method by which V-shaped or single-bevel grooved multi-layer build-up welding is carried out, comprises the steps of welding a first layer by applying a welding current by which a globule transfer pattern is made into a spray pattern by a waveform in which a direct current and a pulse current are caused to overlap, and thereafter welding the second layer by applying a direct current.
摘要:
A welding method is disclosed for butt welding a first base material 1 and a second base material 2 with each other. To also permit stable and efficient formation of a bead in the form of a fillet weld on a back side of a groove by conducting arc welding from the side of the groove without arranging a bead beforehand on the back side of the groove, the first member 1, on which a root face 1a and a single groove face 1b have been formed, is brought at its root face 1a into contact with a flat surface 2a of the second base material 2. A welding wire 6 is arranged facing on the groove formed by the contact between the first base material 1 and the second base material 2. The first base material 1 and the second material 2 are caused to fuse at an area of contact between them by an arc from the welding wire 6. A melt, which has been formed by the fusion at the area of contact and the like, is forced out to the back side of the groove to form a bead B4 in the form of a fillet weld on the back side of the groove.
摘要:
Attempts are made to provide a novel transaldolase gene; a polypeptide encoded by this gene; a recombinant DNA obtained by integrating this gene; a microorganism carrying this recombinant DNA; and a process for producing an aromatic amino acid, an aromatic vitamin, L-histidine, riboflavin, a nucleic acid, a nucleic acid-associated substance, a novel saccharide, etc. by using the above microorganism. As the results of extensive studies, a novel transaldolase gene is isolated from chromosomal DNA of a microorganism belonging to the genus Corynebacterium as a DNA fragment complementary to the requirement for shikimic acid of a transketolase defective variant obtained as a variant with the requirement for shikimic acid belonging to the genus Corynebacterium. Further, a recombinant DNA containing this gene is constructed and transferred into a host microorganism, thereby achieving the objects as described above.
摘要:
A welding torch (4) of a welding robot (RO) is supported by arms (2, 3), to be movable under control by a computer (7). When first and second members (W1, W2) are welded by a weld woven across an interspace between them while oscillating a welding torch (4) along a weld line (WL). Data on changes in the interspace between the first and second welded member (W1, W2) along direction of the weld line (WL) are previously stored in advance to welding. During the welding, the computer 7 performs arithmetic to obtain command values on the basis of the data to output the same to the welding robot (RO), so that the welding robot (RO) performs weaving in accordance with the command values while varying a weaving amplitude of the welding torch (4) in response to the change in the interspace. Changes in the direction in which the welding torch is moved to weave the weld are determined by detecting the actual value of the welding current and reversing direction when the detected value exceeds a prescribed threshold value.
