摘要:
An alignment device comprising a movable table, a plurality of movable support means for movably supporting the movable table, means for reading a recognition mark, and a control means for controlling the drive of the movable support means based on information from the recognition means, wherein each movable support means comprises means having a pair of support blocks each provided to be able to contact/separate with/from the movable table and a pair of piezoelectric actuators each provided with expansible first, second and third piezoelectric elements connected to a support block and extending in each direction, and being capable of walking operation relative to the movable table by the operations of the respective piezoelectric actuators. An alignment accuracy up to a nanometer level can be attained, and the alignment device itself and therefore the entire apparatus incorporating the alignment device can be significantly reduced in thickness and size.

A ceramic holder 2 is mounted on the lower end of a connecting block 30 of metal mounted on the lower end of a tool main body 1 of metal, such ceramic holder 2, a ceramic heater 4 and a ceramic presser 5 being sintered. In addition) the coefficient of linear expansion of the ceramic holder 2 is approximately equal to those of the ceramic heater 4 and ceramic presser 5; furthermore, the thermal conductivities of the ceramic holder 2 and ceramic presser 5 are greater as the pressure side of the ceramic presser 5 as seen from the ceramic heater 4 is approached and are smaller as the attaching surface side of the ceramic holder 2 is approached.
摘要:
A chip mounting device comprising a first recognition means (3) for recognizing a first recognition mark (5) on the upper chip-retainable head (2) side, a second recognition means (4) for recognizing a second recognition mark (6) on the lower substrate-retainable stage (1) side, a third recognition means (18) for recognizing the recognition marks (5, 6) concurrently when the first recognition mark (5) is brought close to or into contact with the second recognition mark (6), and a temperature detection means (17) attached to the first recognition means (3) or the second recognition means (4), wherein calibration is carried out based on the recognition of the recognition marks when the temperature detection means (17) detects a beyond-allowance temperature change, whereby permitting a high-accuracy, efficient calibration independently of mechanical deformation and temperature change in environmental atmosphere.
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).

A recombinant galectin 9 (rGal 9) is provided which exhibits an immune system-mediated action and a direct action on tumor cells (i.e., activity of inducing the intercellular adhesion and apoptosis of the tumor cells), thereby potent in inducing the inhibition of cancer metastasis and reduction. Moreover, the rGal 9 exerts no efficacy on non-activated lymphocytes but can induce apoptosis in activated T cells, in particular, CD4-positive T cells causing an excessive immune response.
摘要:
A pressure application technique is provided that enables two objects to be pressurized (e.g., objects to be bonded) to be positioned with greater accuracy before having pressure applied thereto. The objects to be pressurized are moved relative to each other in a Z direction such that the objects are brought into contact with each other (step S13). Then, a horizontal positional shift ΔD between the objects to be pressurized is measured in the contact state of the objects to be pressurized (step S14). Thereafter, positioning of the objects to be pressurized is again performed by moving the objects to be pressurized relative to each other in the horizontal direction, as a result of which the positional shift ΔD is corrected (step S17).
摘要:
A neutralizing monoclonal antibody specifically reacting with MMP13, a method of neutralizing enzyme activity of MMP13 and an immunological measuring method each using the antibody, as well as a diagnostic agent and a pharmaceutical composition containing the antibody, are provided. Various antibodies to MMP13 have been hitherto obtained, but an antibody having neutralizing activity against MMP13 has not been obtained. The present inventors intensively studied, as a result, found out a neutralizing antibody having specificity for MMP13, resulting in completion of the present invention.
