  • Patent number: 9366423
    Abstract: Disclosed is an LED illumination device of a simple configuration, capable of suppressing thermal resistance to a low level, and of effectively dissipating heat generated from LED elements. Rigidity of a mounting plate is ensured by a wall of a certain height, and thereby the mounting plate now becomes possible to endure saturation vapor pressure of a coolant liquid possibly exerted thereon, and vacuum state or near-vacuum state when the coolant liquid is injected, without being deformed. Since the rigidity of the mounting plate is ensured by the wall, a wall composing a bottom face of recesses may now be thinned, and this is advantageous in view of allowing the heat generated from the LED elements to effectively conduct to the coolant liquid, and of effectively cooling the LED elements.

  • Patent number: 7142989
    Abstract: A computer software program to design an optimum oligo-nucleic acid base sequence candidate from nucleic acid base sequences being analyzed using a computer, the program comprising: a first command to receive the specification of respective tolerated ranges of double-chain bond temperature, base sequence length and GC content, and to store the information on the priority order of respective items in the memory; a second command, while extending the partial sequence in the aforementioned nucleic acid base sequences being analyzed, to determine whether or not a sequence in each length falls within respective tolerated ranges based on the priority items received by the aforementioned first command, and if it does fall within the ranges, to output the partial sequence in the applicable length as an oligo-nucleic acid base sequence candidate; and a third command to display, based on the aforementioned priority order, the oligo-nucleic acid sequence candidate outputted by the aforementioned second command along wit
