  • Publication number: 20190073396
    Abstract: A method, system and computer program product for storing a sub-table by deciding one of a plurality of table storage areas, the sub-tables resulting from partitioning of a table in a database. To provide efficient table partitioning, a database is described for distributively locating a plurality of sub-tables resulting from partitioning of a table in a database. This includes an acquiring section that monitors access occurrences to each of the sub-tables to acquire a history of access occurrences. Also a deciding section decides a table storage area in which a sub-table is to be located, based on the history of access occurrences to each of the sub-tables.

  • Publication number: 20190049370
    Abstract: A gas sensor includes: a gas detection unit including a light source and a detector; and a gas passage including a first end, a second end and a hollow part. The hollow part has a shape in which a cross-sectional area of a flow passage grows smaller. The gas passage includes: a member that divides the hollow part into at least a first area and a second area; a gas inflow port; and a gas outflow port. The gas flows from the gas inflow port into the hollow part, flows in the first area to arrive at the gas detection unit, and the gas located in the gas detection unit flows in the second area and flows out from the gas outflow port.

  • Patent number: 7510553
    Abstract: A temperature measuring unit of a temperature sensor has electrodes disposed on the upper and lower surfaces of a temperature measuring element, thin-film substrates disposed on the upper and lower surfaces of the electrodes, and laser beam shield plates disposed on the upper and lower surfaces of the thin-film substrates. One of the electrodes is bonded to the temperature measuring element by a conductive adhesive, and the other electrode is not bonded to the temperature measuring element by a conductive adhesive. When the temperature sensor is bonded to a hollow cylinder of an insert, the temperature measuring unit is curved along the surface of the hollow cylinder, tending to develop tensile stresses in the other electrode. At this time, the other electrode is positionally displaced depending on the developed tensile stresses, allowing the temperature sensor to be adjusted in length. Consequently, the temperature sensor is prevented from being broken or damaged.
