摘要:
Galectin 9, which is an immune function-controlling factor belonging to a new class that is different from known cytokines and is expected to be used as a therapeutic drug for various immune-related diseases such as an autoimmune disease, has disadvantages (such as high sensitivity to protease and poor solubility) to be solved in developing therapeutic drugs. Therefore, there is a need to overcome these disadvantages. Chemically modified galectin 9, prepared by conjugating a polymer (for example, poly(ethylene glycol: PEG) to galectin 9, in particular, stabilized galectin 9, is verified to exert higher solubility with improvements in pharmacodynamics and pharmacokinetics (for example, prolongation of action potential duration, such as prolongation of blood half-life and others) and in suppression of hemagglutination and thus has excellent characteristics as a drug.

By disclosing part of metastasis mechanisms in cancer cells, the metastatic potential of cancer cells will be determinable. Anti-galectin-9 Ab against galectin-9 is contained as an effective component with or without others, thereby enabling the evaluation or detection of galectin-9 expression levels in cancer cells wherein the metastatic potential of the cancer cells can be assessed or detected.
摘要:
A cell observation support instrument having opposed first and second surface members 115 and 117 and stoppers that are positioned between the first and second surface members 115 and 117 in order to prevent movement of cells. The first and second surface members 115 and 117 form a cell-containing space 110 between opposed surfaces of the members 115 and 117, in order to contain a plurality of cells while allowing movement of the cells. At least one of the first and second surface members 115 and 117 is a member through which an inner side of the cell-containing space 110 can be optically observed from the outside. The stoppers are arranged in the cell-containing space 110, and the number of the stoppers is one or more.

Positioning recognition marks are read by movable recognition device for positioning objects to be bonded to each other. An alignment method includes a step of reading the recognition marks during movement of the recognition device before its complete stop, and a step of identifying absolute positions of the recognition marks by correcting the mark recognition positions having been read based on a position feedback signal of the moving recognition device. A mounting method using the alignment method is also disclosed. It is possible to maintain a high alignment accuracy, eliminate necessity of assuring a settling time for complete stop of the movable recognition device, and significantly reduce the alignment time and mounting tact.
摘要:
A method of accurately calibrating a movement control system of mark recognition means in a chip mounting device, comprising the steps of: recognizing a first recognition mark put on a head (2) and a second recognition mark (13) put on a stage (26) with two-field recognition means (7) so as to calibrate and update the preceding control parameters inputted into the movement control system of the two-field recognition means (7); and, with the head (2) lowered to position the first recognition mark closely to the second recognition mark (13), recognizing both marks with third recognition means (20) when the two-field recognition means (7) is moved back so as to calibrate and update the preceding control parameters inputted into the movement control system of the two-field recognition means (7).

摘要:
A device and method for bonding objects to be bonded each having a metal bonding portion on a substrate, comprising cleaning means for exposing the metal bonding portions to a plasma having an energy enough to etch the surfaces of the metal bonding portions at a depth of 1.6 nm or more over the entire surfaces of the metal bonding portions under a reduced pressure and bonding means for bonding the metal bonding portions of the objects taken out of the cleaning means in an atmospheric air. By using a specific scheme, metal bonding portions after the plasma cleaning can be bonded in the atmospheric air, thereby significantly simplifying the bonding process and the whole device and lowering the cost.
摘要:
A mounting method and a mounting device, the mounting method comprising the steps of, after positioning objects being bonded relative to each other, moving a movable wall positioned therearound until coming into contact with one object holding means to form a local chamber having a local enclosed space, enclosing both objects in the chamber, reducing the pressure in the chamber, moving the object holding means in a direction for reducing the volume of the chamber and moving the movable wall following the movement of the object holding means, and bonding both objects to each other by pressing, whereby, since the part to be bonded and its vicinity can be locally and efficiently enclosed separably from surroundings, and the local chamber capable of properly varying the shape of the enclosed space can be formed interlockingly with the bonding operation while maintaining the enclosed state even at the time of bonding, a specified mounting can be easily performed by a small device.

Positioning recognition marks (A, B, C, D) are read by movable recognition means (5) for positioning objects (2, 4) to be bonded to each other. An alignment method includes a step of reading the recognition marks (A, B, C, D) during movement of the recognition means (5) before its complete stop, and a step of identifying absolute positions of the recognition marks (A, B, C, D) by correcting the mark recognition positions having been read based on a position feedback signal of the moving recognition means (5). A mounting method using the alignment method is also disclosed. It is possible to maintain a high alignment accuracy, eliminate necessity of assuring a settling time for complete stop of the movable recognition means (5), and significantly reduce the alignment time and mounting tact.
