Patent number: 8571646Abstract: An emotional state determining apparatus capable of determining an emotional state of a subject without reducing determination accuracy even if the number of brain wave signals to be used is reduced. A multifractal dimension computing section 3 computes multifractal dimensions based on brain wave signals or brain wave difference signals. An emotional state determining section 4 receives input data on the multifractal dimensions, and determines an emotional state of the subject based on determination criteria which are determined in advance by using as reference data the brain wave signals obtained from a reference person. Generalized latent dimensions (vector) respectively obtained by substituting a plurality of different values determined in advance for a Hurst exponent characteristic q in a generalized latent dimension Dq=1/Hq, which is a reciprocal number of a generalized Hurst exponent Hq obtained from the brain wave signals or the brain wave difference signals, are used as the multifractal dimensions.Type: GrantFiled: February 12, 2010Date of Patent: October 29, 2013Assignee: National University Corporation Nagaoka University of TechnologyInventor: Masahiro Nakagawa

Patent number: 5783833Abstract: A wafer is brought into focus with a projection optical system, and a wafer mark on the wafer is also brought into focus with an off-axis alignment sensor highly accurately according to an automatic focusing process. First, a deviation of the surface of the wafer from an image plane of the projection optical system is measured by an oblique-incidence main AF sensor. For measuring the position of the wafer mark with an imaging device of an alignment system, part of a focusing ray of light from the wafer passes through an optical system, which is not telecentric, composed of an AF relay system and a half beam shield plate, and is detected by the imaging device, whereupon an image of a focusing mark projected onto the wafer is formed on the imaging device. The position of the image of the focusing mark on the imaging device is calibrated on the basis of the deviation which has been measured by the oblique-incidence main AF sensor.Type: GrantFiled: December 12, 1995Date of Patent: July 21, 1998Assignee: Nikon CorporationInventors: Ayako Sugaya, Masahiro Nakagawa
