With a substantially intermediate position as a starting point, a syringe is reciprocated in an X-axial direction with a given reciprocation range by a plurality of times, and a stringiness portion that hangs down from a paste discharge port toward a mask plate is cut off in an intermediate portion thereof. The syringe is traveled to the substantially intermediate position, and with this position as a starting point, the syringe is reciprocated with a reciprocation range smaller than the reciprocation range of the paste cutting operation, and a part of the residual paste hanging from the paste shakes off downward. The syringe is traveled in an end direction of a guide member side, the syringe is rotated about an axial line, and translated into a horizontal storage posture.

A holding mechanism 40 is made up of a shaft support 44 that is provided while joined to a joint and that has a vertically-oriented pivot 44a, a shaft member 45 that horizontally extends from the shaft support 44 and that is turnable around the pivot 44a, and a fitting section 36 that is formed in a squeegee unit 16 and to which the shaft member 45 is removably fitted. Thereby, the entirety of the squeegee unit 16 becomes removably attachable by only moving the squeegee unit 16 in a horizontal direction.

Prior to a mark imaging process executed for the purpose of detecting a position of recognition marks for positioning the substrate and the mask, an optical axis calibration processing process of detecting a horizontal relative position between imaging optical axes, and a surface correction data creation processing process of detecting a local positional deviation of the imaging optical axes, which is caused by the travel of the imaging unit, are executed. Before starting production, a production pre-start precision evaluation process for evaluating a substrate positioning precision is executed by using a verification substrate and a verification mask, and after starting the production, a production post-start precision evaluation process for evaluating a substrate positioning precision after starting the production is executed by using a commercial production substrate and a commercial production mask.

According to one embodiment, a process for producing rare metals includes the steps of: recovering a first-residue solution through a primary target metal extracted by leaching a mineral resource; extracting a perrhenic acid ion contained in the first-residue solution with at least one of an anion exchange resin and a first-organic solvent; back extracting the perrhenic acid ion contained in the anion exchange resin or the first-organic solvent to a first-eluant; and electrolyzing the back extracted first-eluant to collect a rhenium at a cathode.

An object of the invention to provide a screen printing machine allows, during maintenance work for one printing device, the other printing device to continue its screen printing work, and a method for controlling an inside temperature of a screen printing machine. A space surrounded by a base (12) and a cover member (11) is divided into two portions by a partition member (14), and two printing devices (13) are accommodated in two working compartments (15), respectively, which are defined by the base (12), the cover member (11) and the partition member (14), whereby temperature-controlled air is blown into each of the working compartments (15) via an air pipe (71) which branches into two air vents (72) opened to the respective working compartments (15).

To control the differentiation of mesenchymal stem cells into steroid hormone producing cells. Mesenchymal stem cells can be differentiated into steroid hormone-producing cells by being stimulated by a transcriptional factor (SF-1), preferably by the transcriptional factor (SF-1) and cAMP. The present invention is a method for differentiating mesenchymal stem cells into steroid hormone producing cells, comprising stimulating the mesenchymal stem cells by the transcriptional factor (SF-1). The mesenchymal stem cells may be further stimulated by cAMP.
摘要:
An X-Y robot having a structure that linearly deforms along an X-axis direction and a Y-axis direction, a camera reference mark, and a control unit are provided. The X-Y robot causes no displacement of warp or the like and linearly deforms along only the X-axis direction and the Y-axis direction even if heat takes effect due to continuous operation. Therefore, if the amount of expansion and contraction of the X-Y robot due to heat is obtained by picking-up an image of the camera reference mark by a board recognition camera and the component placing position is corrected on the basis of the amount of expansion and contraction, then an electronic component can be mounted in a prescribed position or almost in the prescribed position.

Disclosed are a component recognizing method and apparatus, and a component mounting method and apparatus, by which components with various heights held by a plurality of nozzles can be recognized continuously. The drive of a head is transmitted to nozzles, with surfaces to be recognized of components being controlled so as to be positioned in a recognizable range during respective recognizing operations of the components, and a continuous recognition is thereby made possible. The adjustment of heights of the surfaces to be recognized during the recognizing operations of the components is achieved by one drive unit and a plurality of drive transmitting units.
摘要:
An object of the invention is to provide an electronic component mounting device and a work method of the electronic component mounting device, capable of ensuring safety of an operator who accesses a work line through a door portion, and avoiding reduction of workability. A space defined by a base (11) and a cover member (14) is partitioned by a partition member (15) to define a plurality of work line storing spaces (SP1). A plurality of work lines (12) are stored in the respective work line storing spaces (SP1) individually. When any of a plurality of door portions (14a) provided in the cover member (14) so as to allow an access to an inside of the respective work line storing spaces (SP1) is opened, an operation of a work line (12) stored in a work line storing space (SP1) accessible through the opened door portion (14a) is stopped.
