A textual entailment recognition apparatus (2) includes a vector generation unit (21) that generates, for each of first and second texts, a vector for each predicate-argument structure by using a word other than a word indicating a type of argument of a predicate in the predicate-argument structure; a combination identification (22) unit that compares the vector generated for each predicate-argument structure for the first text and the vector generated for each predicate-argument structure for the second text, and identifies combinations of the predicate-argument structures of the first text and the predicate-argument structure of the second text based on a result of the comparison; and an entailment determination unit (23) that obtains a feature amount for each of the identified combinations, and determines whether the first text entails the second text based on the obtained feature amounts.

An object of the present invention is to provide: a Cu alloy wiring film that makes it possible to use Cu having a low electrical resistivity as a wiring material, exhibit a high adhesiveness to a glass substrate, and avoid the danger of peel off from the glass substrate; a TFT element for a flat-panel display produced with the Cu alloy wiring film; and a Cu alloy sputtering target used for the deposition of the Cu alloy wiring film. The present invention is a wiring film 2 composing a TFT element 1 for a flat-panel display and a sputtering target used for the deposition of the film and the material comprises Cu as the main component and at least one element selected from the group consisting of Pt, Ir, Pd, and Sm by 0.01 to 0.5 atomic percent in total. The wiring film 2 is layered on a glass substrate 3 and further a transparent conductive film 5 is layered thereon while an insulating film 4 is interposed in between.

To provide a game device capable of improving operability of an operation related to a pass between player characters. If a second player character is selected as a pass target while a first player character which is a user operated target is in possession of a moving object, an operated target switching unit (64) switches the user operated target from the first player character to the second player character. A second player control unit (66b) moves the second player character, based on a user operation. A first player control unit (66a) moves the first player character and the moving object, based on the position of a player character belonging to the opponent team. In addition, the first player control unit (66a) causes the first player character to make a pass to the second player character if it is determined that a position/positions of the first player character or/and the moving object and the position of the second player character satisfy a predetermined condition.

Provided is an economical long-life insoluble anode capable of maintaining an anode function stably for a long time even if it is used in a part where severe consumption occurs to generate a cathodizing phenomenon, and also capable of reducing the amount of an electrocatalyst used as much as possible. To realize this, on the surface of a metal substrate 10 composed of a titanium plate, a porous layer 20 including a sintered body of a spherical titanium powder is formed as a base layer. An electrocatalyst layer 30 is formed from the surface of the porous layer 20 to its inside. A part of the electrocatalyst penetrates into the porous layer 20, which provides an incomparably stronger anchor effect than the case of a blast treatment. Even when parts exposed from the porous layer 20 are peeled off and dropped off, the anode function is maintained by the electrocatalyst left in the porous layer 20.

An engine comprises a crank case (1) provided with a lower opening portion (2), which is covered with an oil pan (3) from below, and with a pair of left and right oil passages which extends in a front and rear direction along left and right lateral walls (5) and (6). In this engine, the crank case (1) has the left and right lateral walls (5) and (6) provided with left and right ribs (12) and (13) extending in the front and rear direction. These left and right ribs (12) and (13) are raised inwards from the left and right lateral walls (5) and (6) of the crank case (1). In order to provide left and right oil passages (7) and (8) in these left and right ribs (12) and (13), these ribs (12) and (13) are positioned at the lower opening portion (2) of the crank case (1).

摘要:
The charged particle beams is provided, which can analyze contamination of the inner wall of the system without being disassembled and supply information on appropriate maintenance timing. The contamination level of the inner wall of the system is identified by measuring the spectrum of the X-rays emitted from the inner wall due to irradiation of a charged particle beam or a recoil electron.
