The present invention relates to a cationic electrodeposition coating composition comprising silica particles having pore volume of 0.44 to 1.8 ml/g and average particle size of no more than 10 μm, the composition showing square root of diffusion coefficient (√Tc) of no less than 2.5 upon diffusing a solution onto a coating film therewith; a cationic electrodeposition coating composition comprising silica particles having pore volume of 0.44 to 1.8 ml/g and average particle size of no more than 10 μm, wherein the composition shows minimum deposition pH of 11.90 to 12.00 during electrodeposition coating, and film resistance of 1,000 to 1,500 kΩ·cm2 at film thickness of 15 μm and applied voltage of 240 V; and an article coated with such cationic electrodeposition coating composition. Therefore, the present invention can also provide a coating film formed with the cationic electrodeposition coating composition which can ensure higher corrosion resistance and higher throwing power in addition to other excellent coating properties, even if the resulting coating has extremely thin film thickness (e.g., about 7 μm).

The present invention relates to a setup method for deciding component feeding apparatuses to be attached to each of mounting machines in a component mounting system. The setup method includes a first step of deciding component feeding apparatuses to be attached to each of the mounting machines based on substrate data defining components to be mounted by each of the mounting machines; a second step of determining whether or not there is within the components included in the substrate data a sole mounted component to be mounted by only one mounting machine among the multiple mounting machines; and a third step of deciding, when the determination is made that the sole mounted component exists, to attach component feeding apparatuses feeding the sole mounted component or an alternative component capable of replacing the sole mounted component onto at least one mounting machine other than the only one mounting machine.

The purpose of the invention is to provide a sputtering target formed from a Cu—Ga alloy having a Ga composition of 29 at % or more.[Problem] Since a Cu—Ga alloy becomes a brittle γ phase-single phase structure when the Ga composition becomes 29 at % or more, it cannot be subject to processes such as rolling and forging. Accordingly, the crystal grain size of the cast structure must be small and uniform so that the cast structure can be used as is.[Solution] It is possible to produce a melted and cast Cu—Ga alloy sputtering target containing 29 to 42.6 at % of Ga, and remainder being Cu and unavoidable impurities by continuously solidifying the Cu—Ga alloy sputtering target under solidifying conditions of a constant cooling rate or higher, wherein an average crystal grain size of a sputter front face is 3 mm or less, and a cross section structure of the target is a columnar structure that has grown in a direction from the sputter front face toward a center plane which is parallel to a sputter face.

The present invention provides an indium target and manufacturing method thereof, where deposition rate is high, initial discharge voltage is low, and deposition rate and discharge voltage, from the start of sputtering to the end of sputtering, are stable. In the indium target, an aspect ratio (length of longer direction/length of shorter direction) of crystal particle, observed from cross-section direction of the target, is 2.0 or less.

A zoom lens includes, in order from an object side to an image side, a first lens unit having a positive refractive power, which does not move for zooming, a second lens unit having a negative refractive power, which moves during zooming, a third lens unit having a negative refractive power, which moves during zooming, an aperture stop, and a fourth lens unit having a positive refractive power, which does not move for zooming. The fourth lens unit includes a first lens sub-unit, a focal length conversion optical system configured to be inserted into or removed from an optical path, and a second lens sub-unit. A focal length of the second lens sub-unit, a distance from the aperture stop to a lens surface at the most object side of the second lens sub-unit, and an F-number of the entire zoom lens at a wide-angle end are appropriately set.

Disclosed are new methods comprising the use of in situ hybridization to detect abnormal nucleic acid sequence copy numbers in one or more genomes wherein repetitive sequences that bind to multiple loci in a reference chromosome spread are either substantially removed and/or their hybridization signals suppressed. The invention termed Comparative Genomic Hybridization (CGH) provides for methods of determining the relative number of copies of nucleic acid sequences in one or more subject genomes or portions thereof (for example, a tumor cell) as a function of the location of those sequences in a reference genome (for example, a normal human genome). The intensity(ies) of the signals from each labeled subject nucleic acid and/or the differences in the ratios between different signals from the labeled subject nucleic acid sequences are compared to determine the relative copy numbers of the nucleic acid sequences in the one or more subject genomes as a function of position along the reference chromosome spread. Amplifications, duplications and/or deletions in the subject genome(s) can be detected. Also provided is a method of determining the absolute copy numbers of substantially all RNA or DNA sequences in subject cell(s) or cell population(s).

A zoom lens includes, in order from an object side to an image side and arranged along an optical axis, first to fifth lens units having positive, negative, positive, positive or negative, and positive refractive power, respectively. When zooming, the second lens unit moves monotonically to the image side, the third lens unit moves to the object side in a convex locus, the fifth lens unit moves nonlinearly, and the first and fourth lens units do not move. The fourth lens unit includes a first sub lens unit and a second sub lens unit; the first sub lens unit is an image-stabilizing lens unit that includes a first lens having negative refractive power and a second lens having positive or negative refractive power. The focal length of the fourth lens unit, the focal length of the entire system at the wide-angle end, the Abbe numbers of the materials of the first and second lenses are set appropriately based on predetermined conditions.

A zoom lens system includes four lens units each having positive, negative, negative and positive refractive powers in the stated order from an object side to an image side. A first lens unit includes a variable apex angle prism on the image side of at least one lens element. In this zoom lens system, a focal length of the first lens unit and imaging magnifications of a second lens unit and a fourth lens unit are set appropriately so as to suppress occurrence of decentering aberration accompanying a variation of a prism apex angle.

Methods and compositions for staining based upon nucleic acid sequence that employ nucleic acid probes are provided. Said methods produce staining patterns that can be tailored for specific cytogenetic analyses. Said probes are appropriate for in situ hybridization and stain both interphase and metaphase chromosomal material with reliable signals. The nucleic acid probes are typically of a complexity greater than 50 kb, the complexity depending upon the cytogenetic application. Methods and reagents are provided for the detection of genetic rearrangements. Probes and test kits are provided for use in detecting genetic rearrangements, particularly for use in tumor cytogenetics, in the detection of disease related loci, specifically cancer, such as chronic myelogenous leukemia (CML), retinoblastoma, ovarian and uterine cancers, and for biological dosimetry. Methods and reagents are described for cytogenetic research, for the differentiation of cytogenetically similar but genetically different diseases, and for many prognostic and diagnostic applications.
