An upper reinforcement beam 56 in the railroad tie direction is disposed at the upper portion of the end structure. A plurality of post reinforcement members are disposed in the vertical direction so as to stand on an end beam 26 of the underframe. The post reinforcement members and the upper reinforcement beam are respectively connected by an end post in the vertical direction disposed at an intermediate portion in the end structure width direction and corner posts 54 in the vertical direction disposed at both end portions in the end structure width direction.

The lower inner faces of the post reinforcement members (an end post reinforcement member 57 and a corner post reinforcement member 58) for reinforcing the post members (an end post 53 and a corner post 54) of the end structure are joined to the outer face portion of an end beam 26 of the underframe.

Abstract: A rocking bearing outer ring (12) includes an arcuate track member (13) having a track surface on its inner diameter surface, and a flange portion (14) projecting radially inward from each widthwise end portion of the track member (13). In addition, when it is assumed that L1 represents a circumferential length of the track member (13) and L2 represents a circumferential length of the flange portion (14), 0.2?L2/L1?8 is satisfied.

Abstract: Provided is a railway vehicle having a configuration which can sufficiently protect the cabin even when large external force is applied to the end structures thereof. An end structure 50 is disposed at an end portion of the vehicle body 11 through a crushable zone 40. The end structure is provided with an end post, corner posts, and an upper reinforcement beam 56. The lower end portions of the end post and the corner posts are joined to an end beam 26 of an underframe, and the upper end portions of the end post and the corner posts are joined to the upper reinforcement beam, respectively. In the crushable zone, there are provided a lower slide portion and an upper slide portion. The lower slide portion is configured by connecting a slide center beam projecting from a center portion of an end beam of the underframe in a direction of a cap beam with a guide center beam projecting from the cap beam in a vehicle end direction by a lower fuse member.

Abstract: A communication apparatus transmits a request message to connectable relay apparatuses, and receives a response message from the relay apparatuses. The communication apparatus determines whether the received request message includes the device identification data of a relay apparatus to which it is currently connected. If no received response message includes the device identification data of a relay apparatus to which it is currently connected, the communication apparatus requests another relay apparatus identified based on device identification data that is included in any of the received response messages to make a connection with the communication apparatus.

Abstract: A standard dictionary; a feature extracting unit which extracts features from an input speech; a matching unit which performs matching between the features of the input speech extracted by the feature extracting unit and the standard dictionary; a result outputting unit which outputs a matching result in the matching unit; and a dictionary updating portion which updates the standard dictionary are provided. The standard dictionary is built initially as a dictionary to be used for recognizing speeches produced by any independent speaker; and the dictionary updating unit updates the standard dictionary so as to provide a dictionary to be used for recognizing speeches produced by a dependent speaker based on the result of matching between the features extracted from the input speech and the standard dictionary.

Abstract: A device for speech recognition includes a dictionary which stores features of recognition objects. The device further includes a matching unit which compares features of input speech with the features of the recognition objects, and a dictionary updating unit which updates time lengths of phonemics in the dictionary based on the input speech when the matching unit finds substantial similarities between the input speech and one of the recognition objects.

Abstract: A method and a system substantially eliminates an erroneous voice recognition of repetitive elements in word spotting. One preferred embodiment according to the current invention eliminates erroneous voice recognition of repetitive elements by selectively prolonging a response time of words containing repetitive elements. In order to substantially eliminate the errors, in another preferred embodiment according to the current invention, words containing repetitive elements are marked by a silent key word.

Abstract: A speech recognition system and method having an increased recognition accuracy for a compound word composed of a first word and a second word. Standard information corresponding to each of the registered words is stored. The standard information includes predetermined feature information and time information with respect to each of the registered words. The time information represents a continuous time length for pronouncing each of the registered words at a normal speed. Feature information extracted from an input word is compared with the standard information to obtain a similarity between the feature information and the standard information corresponding to one of the registered words. A determination time is set to determine a result of recognition when the compound word is input and when a first degree of similarity is obtained from the first word at a first time and a maximum degree of similarity is obtained from one of the second word and the compound word at a second time.
