A data processing device () includes a vector generation unit () configured to obtain a number of appearance or a frequency of appearance of a word used in a caption of a row of a cell and in a caption of a column of the cell at which the row and the column of table data intersect with each other and generate a vector which has the obtained number of appearance or the obtained frequency of appearance as a value of an element.

Data processing device, data processing method, and data processing program

A data processing apparatus includes a word selection unit configured to select words corresponding to a part-of-speech type targeted for selection from words disassembled from document data, and a generation unit configured to find, for each of the words selected by the word selection unit, a value obtained by weighting the number of occurrences of each of the words or frequency of occurrences of each of the words according to the part-of-speech type of each of the words to generate a vector with a plurality of the values that are found as values of elements.

A lubricating oil composition for an internal combustion engine, the composition including: a lubricating base oil comprising at least one mineral base oil or at least one synthetic base oil or any combination thereof, the lubricating base oil having a kinematic viscosity at 100&#xb0; C. of 4.0 to 4.5 mm/s and a NOACK evaporation loss at 250&#xb0; C. of no more than 15 mass %; (A) a calcium-containing metallic detergent in an amount of no less than 1000 mass ppm and less than 2000 mass ppm in terms of calcium on the basis of the total mass of the composition; and optionally (C) a viscosity index improver in an amount of less than 1 mass % on the basis of the total mass of the composition.

Lubricating oil composition for internal combustion engine

A lubricating oil composition for an internal combustion engine includes: a lubricant base oil including at least one mineral base oil, at least one synthetic base oil, or any combination thereof, and having a kinematic viscosity at 100&#xb0; C. of 3.0 to 4.0 mm/s and a NOACK evaporation loss at 250&#xb0; C. of no more than 15 mass %; (A) a calcium-containing metallic detergent in an amount of no less than 1000 mass ppm and less than 2000 mass ppm in terms of calcium; (B) a magnesium-containing metallic detergent in an amount of 100 to 1000 mass ppm in terms of magnesium; (G) a zinc dialkyl dithiophosphate in an amount of no less than 600 mass ppm in terms of phosphorus; and optionally (C) a viscosity index improver in an amount of no more than 5 mass %.

A seal plate () seals an opening part of a capacitor case (an exterior case) and includes a main body part () including a through-hole () for discharging a gas (G) in the capacitor case, a pressure valve () arranged to cover the through-hole and including a valve body part () allowing passage of the gas, a storage part () formed in the through-hole to receive the valve body part expanded due to a pressure in the capacitor case, and a stopper (stopper wall) that includes an opening part () for discharging the gas passing through the valve body part and that comes into contact with a portion of the valve body part in the storage part to deform the valve body part. This achieves an increase in gas permeability of the pressure valve and a high operating pressure maintained in the pressure valve.

The present invention provides a lubricating oil composition for internal combustion engines which can reduce sufficiently the friction under mixed lubricating conditions and is excellent in fuel saving properties. The lubricating oil composition comprises (A) a base oil having a 100&#xb0; C. kinematic viscosity of 2 to 8 mm/s and an aromatic content of 10 percent by mass or less, (B) a metallic detergent having a metal ratio of 1.01 to 3.3 overbased with an alkaline earth metal borate, and (C) an organic molybdenum compound with a molybdenum concentration of 0.01 to 0.2 percent by mass on the basis of the total mass of the composition, and having a 100&#xb0; C. HTHS viscosity of 5.5 mPa&#xb7;s or lower.

The present invention provide a lubricating oil composition suitable for internal combustion engines, which composition is excellent in thermal/oxidation stability and can inhibit the increases of the viscosity and acid number even in the presence of NOx and can be used for a long period of time or provide a lubricating oil composition particularly suitable for diesel or direct injection engines equipped with an exhaust-gas after-treatment device such as DPF or various catalysts, which composition is excellent in high-temperature detergency and base number retention properties and further can achieve the effect of inhibit wear caused by soot contamination in the oil occurring significantly when the content of phosphorus compounds such as ZnDTP is decreased, at a high level and can inhibit the exhaust-gas after-treatment device from being adversely affected. The lubricating oil composition comprises a lubricating base oil containing, a specific amount of a base oil with specific properties, and two or more types of additives selected from specific additives.
