Abstract: PROBLEM TO BE SOLVED: To provide a direction detection element capable of being miniaturized and thinned down and accurately detecting the direction of incident light, and a manufacturing method therefor. SOLUTION: Four rectangular contact pads 201-204 are respectively arranged on four PIN photodiodes formed on a substrate. Among the contact pads 201-204, four walls 301-304 radially extended at an angle of 90 degrees to each other with a reference point P as a center are provided. A recess 10 is formed along one side of the walls 301-304 and a groove 11 is formed along the other side and the side around an end part. Rectangular light receiving areas 101-104 of the PIN photodiodes are respectively formed so as to be adjacent through the recess 10 to one side of the walls 301-304. By curving the walls 101-104 along the recess 10, the walls 101-104 are vertically erected.

Abstract: PROBLEM TO BE SOLVED: To provide a detector for an electric wave arrival direction detecting system and its control method, allowing accurate detection of the direction of the maximum received signal strength at all times. SOLUTION: Electric waves of transmission pulses emitted by a transmitter 1 are received while changing the direction of a receiving beam of the electric wave arrival direction detector 10 over all azimuth angles in detecting the maximum received signal strength, thereby, an electric wave arrival direction is detected. Herein, the pulse duration of the transmission pulses are set to be not shorter than a processing time period for receiving the electric waves while changing the direction of the receiving beam of the detector 10 over all azimuth angles in detecting the maximum received signal strength. A controller 35 of the detector 10 detects the rise of the transmission pulses and detects the electric wave arrival direction by receiving the electric waves while changing the direction of receiving beam of a detecting device over all azimuth angles since a detection point, in detecting the maximum received signal strength.

Abstract: PROBLEM TO BE SOLVED: To prevent the load from concentrating on the specific printer and enable to reflect the request of the client side on choosing the printer. SOLUTION: When the printing demand which contains the printing information and the information on the request order is given from the client 12a, the printer server 14 detects the amount of load on each printer 16a-16c and decides the priority order presumptively only on the basis of the detected load amount. Then, the printer server 14 performs fixed arithmetic processing on the order shown by the request order information and the order decided presumptively, and selects the printer to use practically based on the result of the arithmetic operation. When the selected printer and the printer requested the highest priority on the client 12a correspond, the printer server 14 srarts printing promptly by the selected printer. On the other hand, in case both printers do not correspond, the permission demand of the printing is outputted to the client 12a by the selected printer, and the printing is started when the printing is permitted.

Abstract: PROBLEM TO BE SOLVED: To eliminate the trouble at the time of learning a speech recognition device compared with a conventional example and shorten the learning time. SOLUTION: This speech synthesis device 3 selectively speech-synthesizes a plurality of utterance contents of words, sentences, or clauses on the basis of the speech waveform signals of a plurality of speakers, and a parameter learning control part 20 uses the speech-synthesized speech signals of the plurality of speakers and learns, selectively for each kind of the above utterance contents, the parameter of recognition parts of the speech recognition device to be arranged for each of the above kinds. Then, a speech recognition device 4 classifies the inputted speech signals into one of a plurality of prescribed kinds and recognizes them, and on the basis of the speech- synthesized speech signals of the plurality of speakers, the parameter learning control part 20 learns conversion parameters for processing a plurality of feature conversions in feature conversion parts 10-1 to 10-K, and the parameters of a recognition part including a plurality of discriminant functions in discriminant function units 11-1 to 11-K so that the error probability of the speech recognition is minimized.

Abstract: PROBLEM TO BE SOLVED: To easily comprehend the situations of the whole wide area by displaying respective users in a wide area display screen. SOLUTION: This wide area monitoring system 10 uses many compound sensors 12. A compound sensor 12 includes a camera 22, an infrared sensor 26, a tag sensor 28 and a sound sensor 30, mainly photographs a facial image of a user 32 and detects the ID number of an ID tag carried by the user 32. The compound sensor 12 is arranged, in respective zones, closely in a significant zone and sparsely in the other areas. Video data and ID data from the respective compound sensors 12 are collected by a server. The server specifies each user by an ID number and specifies the location of the user to thereby display each user on a wide area display screen. At this time, a user representation form (dot or real image) is controlled in accordance with a preset privacy hierarchy. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a radio communication system which is capable of allocating channels used by radio devices to two or more radio devices. SOLUTION: The radio device 114 connected to a cable network allocates channels of frequency f1 for transmission and sends information as to the allocated channels to the radio devices 111 and 115. The radio devices 111 and 115 allocate channels of frequency f0 different from the frequency f1 for transmission resting on the channel information sent from the radio device 114. The radio devices 111 and 115 send channel information indicating the allocated channels to adjacent radio devices. The above procedure is repeatedly carried out, so that channels can be allocated to all the radio devices 101 to 116 which constitute the radio communication system 100. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a wireless device capable of constituting a wireless network by which further higher throughput can be obtained. SOLUTION: The wireless device has a control channel and a data channel. The wireless device transmits a communication request RTS to a transmission destination with an omnidirectional beam pattern by using the control channel, and establishes a wireless communication route in-between a reception destination by receiving communication permission CTS from the transmission destination while changing a beam pattern of an antenna into a plurality of beam patterns. When the wireless communication route is established in between the transmission destination, the wireless device transmits data DATA to the transmission destination via the data channel different from the control channel by using a beam pattern, in which radio field intensity is maximum when receiving the communication permission CTS, and receives an acknowledgement ACK from the transmission destination.

Abstract: PROBLEM TO BE SOLVED: To provide an information retrieval and display system capable of easy information retrieval and display without need of inputting a keyword by manual input operation using a keyboard, etc. SOLUTION: An information retrieval and display system 10 includes a memory 32 (36). For each keyword, image information and audio information related to the keyword and icons to identify them are stored in advance in the above memory. A computer 26 displays the keyword stored in the memory by a projector 30. When an operator touches the keyword displayed on the screen, the computer detects the touch, determines a display sequence of the relevant information related to the keyword, and makes the projector display the icons in an infinitely circular way, according to the display sequence. When an operator touches and depresses one of the icons, the relevant information indicated by the touched icon is displayed by the projector. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a method of generating a translation model in a statistical machine translator improving translation performance. SOLUTION: This method of generating the translation model in the statistical machine translator comprises a first step of extracting hierarchical phrase alignment from two-language corpus, a second step of converting the word string of the two-language corpus into a chunk string by dividing the two- language corpus into chunks which are meaningful groups, and a third step of training the translation model with the chunk as a unit on the basis of the two-language corpus converted in the second step.
