| 20110073603 | SAMPLE LOW-TEMPERATURE STORAGE CASE AND ORGANISM TRANSPORTATION SUPPORTING SYSTEM - The storage case has a structure in which a sample storage case (S) contained in a storage case is cooled and held at a low temperature by a Stirling refrigerator. A detection element is disposed in a room-temperature area of the storage case. The chemical or physical property of the detection element varies when a contaminant adheres to the detection element. Entrance of a contaminant into the storage case can be checked by contactlessly checking the detection element from the outside of the storage case. The storage case includes a server for receiving the result of the check from the detection device, storing the result, and setting up connection via a communication line to at least two out of a terminal operable by the forwarder, a terminal operable by the carrier, and a terminal operable by the recipient to transmit the result to the two. | 03-31-2011 |

| 20100097581 | PROJECTION OPTICAL SYSTEM - A projection optical system receives light from a display device surface and enlarges and projects a display image thereon onto a screen surface. The projection optical system includes one or more reflective surfaces having an optical power between the display device surface and the screen surface, moves at least one optical device having an optical power to adjust focus and satisfies the following conditional formula: −0.02<{(δ1−δ2)β2}/{(δ1+δ2)β1}<0.2 where δ1 and δ2 represent, when the absolute value of a projection magnification is the highest and the lowest, respectively, during focus adjustment, the absolute value of a difference between a distance from the exit pupil of rays incident on the screen upper ends of the screen surface to the screen surface and a distance from the exit pupil of rays incident on the screen lower ends of the screen surface to the screen surface and β1 and β2 represent the maximum value and minimum value, respectively, of the projection magnification when focus is adjusted. | 04-22-2010 |

| 20090301621 | PNEUMATIC TIRE - Provided is a pneumatic tire capable of providing improved lateral sliding resistance on show, improved traction on snow, and improved uneven-wear resistance. The provided tire includes: at least one circumferential main groove formed in a tread portion and extending in the tire-circumferential direction; and plural columns of land areas defined in the tread portion by the circumferential main groove. Plural lug grooves and plural sipes are formed in at least one of the plural land-area columns. Each of the lug grooves extends in the tire-width direction. At least one end of each lug groove is formed as a dead end located in the corresponding land area. Each of the sipes extends so as to surround the corresponding lug groove. Each sipe intersects with the lug groove in question, and is communicatively connected to the corresponding single one of the circumferential main grooves at the two ends of the sipe. | 12-10-2009 |
