| 20110050258 | DEVICE FOR DETECTING SPACE OBJECTS - The present invention has the object of simplifying apparatus configuration and avoiding a requirement for calibration. The present invention achieves the above object by forming a detection sheet element that retains in a predetermined array pitch a plurality of conductive detection lines that are lead lines formed by etching or the like on a non-conductive thin film that can be exposed in a space environment. A detection circuit connected to each detection line of the detection sheet element is provided. When an object flying in space collides with the detection sheet body, since a detection line on the detection sheet element is ruptured, constant monitoring of the conductivity of the detection line by the detection circuit enables detection of the object flying in space that has collided with the detection sheet element when a detection line is ruptured. Furthermore a means of solution is adopted in which an effective diameter of a colliding object flying in space can be detected from the number of severed detection lines. | 03-03-2011 |

| 20090015553 | IMAGE DISPLAYING APPARATUS, IMAGE DISPLAYING METHOD, AND COMMAND INPUTTING METHOD - A disclosed image displaying apparatus comprises: a photographing unit configured to photograph an image on a screen; a projection image generating unit generating the image to be projected on the screen; an image extracting unit extracting identification information from the image photographed by the photographing unit, the identification information concerning object or figure information; an object recognizing unit recognizing attribute information from the identification information concerning the object information extracted by the image extracting unit; a figure recognizing unit recognizing characteristic information from the identification information concerning the figure information extracted by the image extracting unit; and an operation processing unit operating the projection image generating unit based on the attribute information and characteristic information. | 01-15-2009 |
| 20090115093 | POLYVINYL CHLORIDE FIBER FOR ARTIFICIAL HAIR, MANUFACTURING AND APPARATUS OF THE SAME - The present invention is to provide a polyvinyl chloride (PVC) fiber for artificial hair. The PVC fiber is manufactured by melt spinning a PVC resin composition with a nozzle, wherein the nozzle has a nozzle hole having a diameter D and a land length L, and a nozzle leading portion having a cone angle, and wherein a ratio of L/D is 1-3, a height of the nozzle leading portion is at least 4 mm, and the cone angle is 20°-90°. The resulting PVC fiber has an arithmetic mean roughness of 0.18-0.38 μm and a maximum height of 0.5-3.5 μm along a longitudinal direction, specified by JIS B 0601. | 05-07-2009 |
| 20090207383 | PROJECTED IMAGE DISPLAY UNIT - There is provided a projected image display unit characterized by a display surface configured to display an image; projection means for projecting the image onto the display surface; and image capturing means for performing image capturing on the display surface, the image capturing means being placed on the same side of the display surface as the projection means, wherein the image capturing means is placed at a position so that the symmetrical position of the projection means with respect to the display surface is out of the range of the angle of view of the image capturing means. | 08-20-2009 |
| 20100233390 | VINYL CHLORIDE RESIN FIBER AND METHOD FOR PRODUCING SAME - To provide a fiber made of a vinyl chloride resin which is excellent in heat resistance and thus hardly shrinks thermally even at a temperature exceeding 100° C. | 09-16-2010 |

| 20110244813 | COMMUNICATION SYSTEM - This communication system is equipped with a plurality of transceiver devices each composed of a transmission device that transmits unit data and a reception device that receives unit data from the transmission device. The transmission devices are connected in series. Each of the transmission devices stores identification information for identifying the device itself. The transmission device accepts unit data from a front stage side. The transmission device generates identification information for identifying one of the transmission devices from information included in the accepted unit data, in accordance with a predetermined generation process. In a case that the generated identification information corresponds to the stored identification information, the transmission device transmits the accepted unit data to the reception device. In a case that the generated identification information does not correspond to the stored identification information, the transmission device sends the accepted unit data to a back stage side. | 10-06-2011 |

| 20080274289 | Mold Device and Method of Manufacturing Cylinder Block - A mold device and a method of manufacturing a cylinder block. The mold device comprises a split core having two first split cores formed so that the tip parts thereof may be in a tapering shape, two second split cores installed between the first spilt cores, and an inner core is installed at the center part and pushing out the first split cores in the direction receding from the center axis thereof. When the inner core is pushed out to push out and position the first spilt cores, both end parts of the second split cores are brought into contact with the tip parts of the adjacent first split cores, and the outer side-faces of the first split cores and the outer side-faces of the second split cores form a cylindrical shape. When the inner core is raised, the first split cores and the second split cores are pulled to the axial center by first engagement pieces and second engagement pieces. | 11-06-2008 |

| 20120075816 | CIRCUIT DEVICE AND METHOD OF MANUFACTURING THE SAME - In a hybrid integrated circuit device of the present invention, leads are fixedly attached on the upper surface of a circuit board. The lead includes an island portion, a slope portion, and a lead portion. A transistor and a diode are mounted on the upper surface of the island portion. Electrodes provided on the upper surfaces of the transistor and the diode are connected to a bonding portion through a fine metal wire. The bonding portion of the lead is disposed at a higher position than the island portion. Thus, the fine metal wires connected to the bonding portion are separated from each other. | 03-29-2012 |
