摘要:
A zoom lens system includes, in order from the object side to the image side, four lens units having positive, negative, negative and positive refractive powers. A first lens unit includes, in order from the object side to the image side: a front subunit having a negative refractive power; a middle subunit that has a positive refractive power and moves during focusing; and a rear subunit having a positive refractive power. The zoom lens system further includes a variable apex angle prism disposed on the image side of the front subunit. An average Abbe number of materials of a negative lens element and a positive lens element included in the front subunit is set appropriately so as to suppress occurrence of decentering aberration accompanying a variation of a prism apex angle.

The fourth lens unit includes a front subunit and a rear subunit, the rear subunit being constituted by two negative lenses and at least three positive lenses. The rear subunit includes a first rear-subunit and a second rear-subunit. Each of the first rear-subunit and the second rear-subunit includes a negative lens and at least one positive lens. Lens materials are suitably set for the first rear-subunit and the rear second-subunit.

An optical accessory having a high optical performance arranged to change an optical characteristic of a shooting lens and to be attached on the object side of a shooting lens is provided. The optical accessory FE is to be detachably attached to the object side of a master lens M and has at least one lens FE having a negative refractive power. The image-side surface r2 of the lens FE is designed to have an aspherical shape having a negative refractive power that decreases toward its periphery.

A zoom lens comprises a first lens unit that does not move for zooming and that has a positive refractive power, a second lens unit that is configure to move to an image side during zooming from a wide angle end to a telephoto end and that has a negative refractive power, a third lens unit that is configured to reduce image plane variation due to zooming, and a fourth lens unit that does not move for zooming. The fourth lens unit comprises a fourth-F unit, a fourth-B1 unit, and a fourth-B2 unit. The average Abbe number of positive lens and negative lenses in the fourth-B1 unit and the average Abbe number of positive negative lenses in the fourth-B2 unit are set appropriately.
摘要:
Methods and compositions for staining based upon nucleic acid sequence that employ nudeic 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.

摘要:
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).

摘要:
A semiconductor device is constructed to have an insulating layer containing an impurity provided upon a semiconductor substrate. This insulating layer contains a plurality of windows of different sizes. A first layer is provided in the windows. This first layer does not extend over a periphery of the windows to the surface of the insulating layer. Further, this semiconductor device is constructed such that the surface of the insulating layer and the first layer opposite the semiconductor substrate are flat. In addition, the semiconductor substrate in contact with the first layer also contains the impurity. The semiconductor device, having less surface unevenness that a conventional device, provides both improved and greater stability of device properties.

Also disclosed is a process comprising previously forming a plurality of conductive regions 105 and 107, thereafter forming an opening 110 that opens at the conductive regions, and depositing another conductive region 109 in the opening 110 to electrically connect the respective conductive regions in the opening. This can achieve a wiring connection structure that enables prevention of an increase in the number of masks used to form openings for wiring connection, an increase in the number of steps and an increase in the area held by openings, to thereby enhance the degree of integration of semiconductor devices.
