Abstract: One embodiment of the present invention provides a nonwoven fabric containing silk fibers in which an abs intensity ratio [abs (1650)/abs (1620)], which is a ratio of an intensity of a peak positioned in a vicinity of 1650 cm?1 [abs (1650)] in an infrared absorption spectrum to an intensity of a peak positioned in a vicinity of 1620 cm?1 [abs (1620)] in an infrared absorption spectrum, is larger than 0.65 and 1.90 or less, and a method for producing the nonwoven fabric containing silk fibers.

Abstract: A database management system receives a new data table input to a database; and executes unique constraint determination processing of determining whether each comparison-subject value as each value registered in a target column in the new data table is different from each comparison reference value as each value registered in a target column in a stored data table in the database, and stores the new data table in a second database area different from a first database area storing the stored data table in the database when a determination result obtained in the unique constraint determination processing is true.

Abstract: A curable silicone resin composition according to the present invention includes at least the following components: (A) a silicone resin having a hydrogen atom bonded to silicon atom (as SiH group); (B) a silicone resin having a vinyl group bonded to silicon atom (as Si—CH?CH2 group); and (C) a platinum catalyst, wherein the total amount of silanol (Si—OH) group in the components (A) and (B) is 0.5 to 5.0 mmol/g; and wherein the amount of platinum in the component (C) relative to the total mass of the components (A), (B) and (C) is 0.003 to 3.0 ppm in mass units. A cured product obtained by heating the composition is suitably usable as an encapsulant of an optical semiconductor device.

Abstract: Disclosed is a curable composition including a silicone (A) of a specific structure and a composition containing Si—OH group and Si—H group, a silicone (B) of a specific structure and a composition containing Si—OH group and Si—CH?CH2 group, and a hydrosilylation catalyst of a catalytic quantity containing at least one metal compound selected from the group consisting of platinum compounds, palladium compounds, and rhodium compounds. In this curable composition, as kind of each silicone and the content of Si—OH group are adjusted, in curing the silicone, foaming in a cured product can be inhibited by inhibiting a dehydration condensation reaction between Si—OH groups, as compared with a hydrosilylation reaction which is a reaction of Si—CH?CH2 group and Si—H group. Furthermore, an excellent adhesion to a base body such as semiconductor substrate can be given when making a cured film.

Abstract: Provided is a computer system including: an active system; and a standby system. The active system generates, when an update request is received, an after-update log, and sends the after-update log to the standby system at a predetermined timing. The standby system generates a before-update log based on the after-update log sent from the active system and the stored data, updates, after the before-update log is generated, the stored data based on the after-update log, and rolls, when a rollback request is received, the data back to the data before update based on the generated before-update log. Accordingly, it becomes possible to suppress an increase in period of time to reflect the data updated in the active system on the standby system, and to suppress an increase in period of time for rollback of the data performed in the standby system.

Abstract: There is provided a method of creating an index, which is executed in a document retrieval apparatus. The index includes index information and a trie, the index information includes an index item formed of a character string, the trie is formed of a plurality of nodes each including a part of the character string of the index item, and the index information and each of the plurality of nodes of the trie are associated with each other. The method comprises the steps of: dividing the index information by a unit of an index information block when a first node of the trie is associated with a plurality of the index information blocks, and a search time required for searching all the index information associated with the first node of the trie exceeds a predetermined first threshold; and associating the divided index information with the second node.

Abstract: In a cooling air passage in a gas turbine stationary blade shroud a groove at a shroud end face is formed to extend along the shroud end face. An open portion of the groove is covered by a plug so as to form a cooling air passage. A cooling air passage in which the work accuracy is remarkably enhanced can thus be very easily worked. Preferably the cooling air passage is formed by electric discharge machining (EDM). The same process can be used to form an open portion of the groove, as well as any desired turbulators. The open portion of the groove is closed by a plug which is brazed or welded in place.
