    • A polishing pad used in a CMP step in the manufacture of a semiconductor integrated circuit device is relatively expensive; thus, it is necessary to avoid a wasteful exchange of the pad. Accordingly, it is important to measure the abrasion amount of this pad precisely. However, in ordinary measurement thereof through light, the presence of a slurry hinders the measurement. In measurement thereof with a contact type sensor, a problem that pollutants elute out is caused. In a CMP step in the invention, the height position of a dresser is measured while the dresser operates, thereby detecting the abrasion amount or the thickness of a polishing pad indirectly. In this way, the time for exchanging the polishing pad is made appropriate.
    • 用于制造半导体集成电路器件的CMP步骤中的抛光垫相对昂贵; 因此,有必要避免浪费的垫的更换。 因此,重要的是精确地测量该垫的磨损量。 然而,在通过光的普通测量中,浆料的存在阻碍了测量。 在使用接触型传感器进行测量时,引起污染物排出的问题。 在本发明的CMP步骤中,在修整器操作时测量修整器的高度位置,从而间接地检测抛光垫的磨损量或厚度。 以这种方式,更换抛光垫的时间是适当的。

    • It is an object of the invention to relax magnetic saturation and realize a high-performance magnetic shield effect that is suitable for magnetic devices such as an MRAM. A magnetic shield member of the invention is suitable for a magnetic memory device in which a magnetic random access memory (MRAM) consisting of a TMR element formed by stacking a magnetization fixed layer with a direction of magnetization fixed and a magnetic layer, in which a direction of magnetization can be changed, via a tunnel barrier layer is sealed by a sealing material such as resin. A planar shape or a sectional shape of magnetic shield plates provided on the sealing material in order to magnetically shield the MRAM is a shape in which a side substantially perpendicular to a direction of an outer magnetic field and a side substantially parallel to the direction of an outer magnetic field are not orthogonal to each other, in particular, circular, polygonal, or the like, whereby it is possible to relax magnetic saturation of the magnetic shield plate and keep the magnetic shield effect.

    • The present invention provides methods for treating ischemic diseases, which comprise the step of administering angiopoietin-1 (Ang1) or an Ang1-encoding vector. The present invention also provides ischemic disease treatment kits which comprise Ang1. Ang1-expressing vectors were prepared, and each was administered alone intramyocardially to rats in the acute phase of myocardial infarction to express Ang1 in the local cardiac muscle. The results indicate that marked effects have been obtained, such as decrease in post-infarction mortality rate, increase in blood vessel number in myocardium, reduction of myocardial infarct size, and improvement of cardiac function. Administration of the required VEGF was not necessary for the angiogenic activity of Ang1. Furthermore, when an Ang1viral expression vector was administered alone to an animal model of severe limb ischemia, in which ischemia had been induced by arterial ligation, a remarkable limb salvage effect was obtained. The Ang1 gene therapy is excellent as a safe and effective therapeutic method for ischemic diseases such as ischemic heart diseases and limb ischemia.
    • 本发明提供治疗缺血性疾病的方法,其包括给予血管生成素-1(Ang1)或Ang1编码载体的步骤。 本发明还提供了包含Ang1的缺血性疾病治疗试剂盒。 制备Ang1表达载体,并在心肌梗死急性期内单独给予心肌内的大鼠,以在局部心肌中表达Ang1。 结果表明,已获得显着效果,如梗死后死亡率降低,心肌血管数量增加,心肌梗死面积减少,心脏功能改善等。 所需VEGF的施用对于Ang1的血管生成活性是不必要的。 此外,当将Ang1病毒表达载体单独施用于通过动脉结扎诱导缺血的严重肢体缺血的动物模型时,获得了显着的肢体补救效果。 Ang1基因治疗作为缺血性心脏病和肢体缺血等缺血性疾病的安全有效的治疗方法是优秀的。

    • In an encoder signal interpolation divider (1) that automatically corrects errors in the offset and gain of an input signal at a high speed with a low cost circuit configuration, and can accurately generate an encoder signal having a predetermined resolution by interpolation division, analog input signals (A1, B1) are subjected to offset correction by a 0-point correction circuit (13) in adders (4, 5) prior to being digitally converted by A/D converters (8, 9), and are subjected to gain correction by an amplitude correction circuit (14) in amplifiers (6, 7). The corrected analog signals are converted to digital values, angle data is calculated in an angle data lookup table (10), and, based on these results, an encoder pulse signal having a predetermined resolution is generated and output from an encoder pulse signal generating circuit (12).
