Patent number: 9488812Abstract: To provide thin imaging optics that have magnification-adjustment functionality and can fit in a small-form-factor electronic device that has limited thickness or layout space. These imaging optics, which have magnification-adjustment functionality that allows magnification adjustment, are characterized in that a prism (P) with the ability to bend the optical axis by 90° is positioned on the object side. These imaging optics are also characterized in that at least the following are laid out, in this order, behind the optical-axis bending means: a positive-power first group (G1) that produces an intermediate image (II), said intermediate image (II) being a real image; a positive-power second group (G2) that refracts off-axis light rays toward a central axis (O); and a positive-power third group (G3) that focuses the intermediate image (II) onto an imaging element. Light-ray heights at the V-edges throughout the imaging optics are thereby kept low.Type: GrantFiled: November 15, 2013Date of Patent: November 8, 2016Inventor: Akira Yabe

Patent number: 7852571Abstract: Generally, it is difficult to previously know an adequate position of a special optical surface such as an aspherical surface, a diffraction optical element, or an eccentric surface in an optical system. If a trial of designing an optical system with all the possible surface numbers is made, the number of combinations is very large, and the designing is often impossible. The invention solves such a problem and provides means for automatically and efficiently finding out the most suitable surface number of a special optical surface. According to the invention, the surface number of a special optical surface different from a spherical surface is expanded to a real number value, the constitution of an optical system including a special optical surface having a real number value surface number is defined, the real number value surface number is used as an independent variable for optimizing the optical system, and the best surface number of the special optical surface is determined.Type: GrantFiled: May 13, 2005Date of Patent: December 14, 2010Inventor: Akira Yabe

Publication number: 20060054205Abstract: The present inventors have found the presence of a nanobubble that has not been confirmed conventionally, and established a method for producing nanobubbles. The inventors have determined the theoretically expected characteristics of the produced nanobubbles, found new characteristics by analyzing data experimentally collected, and elucidated the relationship among the characters. Specifically, the inventors have found that a nanobubble has features such as decrease of the buoyant force, increase of the surface area, increase of the surface activity, generation of a local high-pressure field, interface activating action, and sterilizing action thanks to electrostatic polarization. By the association among the features, any of wide variety of objects can be cleaned with high performance and with light environmental load thanks to the function of adsorbing foul components, the function of cleaning the surface of an object quickly, and the sterilizing function, and polluted water can be purified.Type: ApplicationFiled: September 30, 2003Publication date: March 16, 2006Inventors: Akira Yabe, Mizuki Goto

Patent number: 6895334Abstract: Optical properties with high non-linearity such as a modulation transfer function (MTF) are efficiently optimized at high speed compared to conventional methods. An optimal solution of an optical system is obtained in a first optimization unit using a merit function on aberration. Weights or target values of the merit function on aberration is automatically adjusted in a second optimization unit in a manner that an evaluated value of the MTF or the like approaches a desired value. The first optimization unit re-optimizes the optical system using the weights or target values which have been automatically adjusted. Thus, automated is a function equivalent to the operation which has been conducted by a designer such as adjustment to weights or target values.Type: GrantFiled: February 7, 2001Date of Patent: May 17, 2005Assignee: Fujinon CorporationInventor: Akira Yabe
