| 20120041275 | DERIVATION METHOD OF DISCRIMINATION THRESHOLD OF NAIL APPARATUS MELANOMA - An derivation method of a nail apparatus melanoma discrimination threshold includes a first step of assuming a color image of longitudinal melanonychia as three-dimensional vectors each composed of RGB parameter values of each pixel and finding an angle between each of the three-dimensional vectors and a reference vector, a second step of finding a probability of occurrence according to a frequency distribution of the angles found in the first step, and a third step of finding, according to the probability of occurrence found in the second step, a threshold for a parameter to discriminate whether the longitudinal melanonychia is malignant or benign. | 02-16-2012 |
| 20120012102 | SOLAR POWER CONCENTRATING SYSTEM - An outer side of a receiver is covered with a housing, so that the receiver is not exposed to the open air and no heat of the receiver is taken by winds, to improve thermal efficiency. Although the outer side of the receiver is covered with the housing, a lower side thereof has an opening, so that sunlight reflected by heliostats is introduced through the opening to the inside of the receiver and is surely received by an inner face of the receiver. | 01-19-2012 |
| 20110279826 | NONCONTACT SURFACE SHAPE MEASURING METHOD AND APPARATUS THEREOF - Even if a return beam from a work to be measured does not agree with the center of a two-piece sensor, a correction value is calculated according to a voltage difference between two sensors of the two-piece sensor if the voltage difference is within a neighborhood range. The correction value is added to an actual position of an objective lens in an up-down direction, to calculate a movement amount of the objective lens up to a focused state (a state in which the return beam agrees with the center of the two-piece sensor). | 11-17-2011 |
| 20110253128 | SOLAR HEAT EXCHANGER - A light receiving plate floating on the surface of tin, i.e., a low-melting-point heating medium and receiving solar beams is made of solid carbon material entirely coated with a silicon carbide film. Due to the silicon carbide film, the surface of the light receiving plate is black to realize a high absorption ratio of the solar beams. In addition, the light receiving plate is made of the silicon carbide film at least at the surface thereof, to demonstrate excellent heat resistance. | 10-20-2011 |
| 20110170178 | STEREOMICROSCOPE - A stereomicroscope includes a microscope main body and a camera for assistant. The microscope main body includes therein an objective optical system, a zoom optical system and an eyepiece optical system. The camera for assistant is detachably mounted to the microscope main body. The microscope main body provides to a main operator a pair of optical images including a certain binocular disparity as viewed from an observation direction of the main operator. The camera for assistant provides to an assistant a pair of electron images including a certain binocular disparity as viewed from an observation direction of the assistant. The observation directions of the main operator and the assistant cross at a certain angle. The camera for assistant outputs the pair of electron images into a stereo viewer which is separated from the microscope main body. | 07-14-2011 |

| 20110080536 | STEREOSCOPIC IMAGE DISPLAY APPARATUS - An electronic image display panel is a reflective liquid crystal panel. With respect to the surface of the electronic image display panel, an optical axis of an eyepiece lens is perpendicular. The optical axis passes through a central part of the electronic image display panel that is a main observation point of an observer. When observing the electronic image display panel, a visual axis of an eye of the observer forms no large angle with respect to the electronic image display panel and the observer can stereoscopically observe electronic images displayed on the electronic image display panels at an original binocular parallax provided by an objective lens of a surgical microscope. As a result, the observer feels no eye fatigue or headache even when observing the images for a long time. | 04-07-2011 |

| 20100259815 | STEREOMICROSCOPE - A stereomicroscope has a rotary mirror to switch an optical path of a beam from an objective optical system between a normal optical path A and an image optical path B. Accordingly, a main operator D | 10-14-2010 |
| 20090213362 | OPTICAL MEASURING SYSTEM - An optical measuring system has a first optical measuring instrument and a second optical measuring instrument. The optical measuring system includes a first optical path to guide a first beam from a measuring region to the first optical measuring instrument, a second optical path to guide a second beam from the measuring region to the second optical measuring instrument, an optical system through which the first and second optical paths extend and in which the first and second optical paths are paraxial, a reflection area to change the direction of the first optical path, the second optical path crossing the reflection area, and a light transmission area arranged at a position where the reflection area and second optical path cross each other, the light transmission area having a higher light transmittance than the reflection area. | 08-27-2009 |

The first binocular microscope includes an objective lens, a first right ocular lens which provides a first image based on a light flux transmitted through the objective lens, and a first left ocular lens which provides a second image based on a light flux transmitted through the objective lens. The first display device can be disposed opposite to or in alignment with the first binocular microscope, and includes a first right-eye image display surface for displaying the first image and a first left-eye image display surface for displaying the second image. The first display device can be reversed about a horizontal axis extending in a direction along which the first right-eye image display surface and the first left-eye image display surface are located in alignment. | 07-30-2009 |
| 20080266569 | NONCONTACT SURFACE FORM MEASURING APPARATUS - A noncontact form measuring apparatus emits a laser beam L. In the apparatus, a prism bends the laser beam into an X-axis direction, so that a Z-axis displacement of an objective optical system is converted by the prism into an X-axis displacement on a measurement coordinate system. A movement of an X-axis stage is converted into a Z-axis displacement on the measurement coordinate system. The apparatus moves an internal gear as a measurement object and the prism, reads X, Y, and Z coordinates at each focal point, and measures a three-dimensional form of inner teeth of the internal gear. The apparatus may translate the internal gear in a Y-axis direction, to measure a partial form of the inner teeth. The apparatus may turn the internal gear in an angular θ-direction, to measure a whole circumferential form of the inner teeth. | 10-30-2008 |
