摘要： PURPOSE:To provide the portable speech input monitor controller which can speedily and easily monitors a speech recognition result, and correct an input and/or confirm a process output when data are inputted to a computer remotely by using a speech input device. CONSTITUTION:A headset microphone 1701 and a portable display 1801, connected to a radio equipment (mobile station) 1601, is carried. A speech recognition device 1301 is connected to a radio equipment (fixed station) 1501 and a storage device 1401 for the speech recognition result is connected thereto. Further, an input processor 1201 for outputting an operation command to a plant 1001 through a controller 1101 on the basis of the recognition contents is connected to the speech recognition device 1301. Thus, a speech is inputted remotely from a place distance from the speech recognition device, a computer, etc., the recognition result of the speech recognition device which recognizes the speech input is monitored on the screen of the carried display device, and correction and/or input control to the computer is performed.

摘要： PROBLEM TO BE SOLVED: To provide a supporting method and device capable of judging the mental state of an operator for performing operations by voice input and performing operator supporting suited to the mental state. SOLUTION: In a voice recognition processing part 3, the pattern of the instruction word of a plant operation voice inputted beforehand is registered for each operator. During the operation, for a voice instruction word from a microphone 6, the sound pressure waveform is fetched through a data conversion part 2 to the voice recognition processing part 3 and a maximum sound pressure, a highest frequency and shortest sounding time are fetched to an operator state judgement processing part 4. The voice recognition processing part 3 divides the sound pressure waveform and performs spectrum conversion for respective sound pressure data and performs the voice recognition of the instruction word by pattern matching. Also, the operator is specified by speaker recognition. The operator state judgement processing part 4 compares the inputted maximum sound pressure, highest frequency and shortest sounding time with the registration data of the specified operator respectively and judges the mental state. A supporting processing output part 5 executes a supporting processing corresponding to instruction contents when the mental state of the operator is 'abnormal'.

摘要： PURPOSE: To detect the presence of gas by detecting the light absorption of gas to be detected by laying an optical waveguide along a long distance monitor area and providing a light transmitter to one end thereof while providing a photodetector to the other end thereof to transmit and detect detection light. CONSTITUTION: A long optical waveguide 2 is laid in a tunnel 1 and a light transmitter 7 is provided to one end of the waveguide and a photodetector 8 is provided to the other end thereof. When detection light is sent from the light transmitter 7, it is repeatedly reflected to advance through the waveguide and detected by the photodetector 8. The detection light is absorbed by gas (a) during this period and attenuated to reach the photodetector 8. The lowering of the intensity of the detection light is detected by the photodetector 8 to know the average concn. of the gas (a) in the tunnel 1. By this constitution, the number of machineries required in the detection of the gas is reduced even in the long distance monitor area and the cost required in the initial time and for maintenance is reduced.

摘要： PURPOSE:To input a voice even to the executing operation of a plant. CONSTITUTION:Once the voice input/output device 3 recognizes data setting, status setting, etc., an MMI control part 7 enters an input wait state and then the voice input/output device 3 narrows down a recognition object to 'execute' and 'cancel'. When the voice of 'execute' or 'cancel' inputted by an operator is correctly recognized, the MMI control part 7 performs the process for 'execute' or 'cancel' for the 1st time.

摘要： PROBLEM TO BE SOLVED: To provide a reader in which a business form is imaged and its content is recognized based on a format definition, where the effect of fluctuation in distance between an imaging part and a business form is suppressed. SOLUTION: In a business form reader, an address label attached on the upper surface of a parcel is imaged from above using an imaging part 20 fixed to a stand. The actual fineness that fluctuates according to height of a parcel is calculated by imaging a guide 31 of known dimension which is disposed on the upper surface of the parcel. The zooming factor of a lens 21 is controlled so that the actual fineness agrees with a specified fineness which is specified by a format definition used for recognizing the content of the address label. With this configuration, a difference between the actual fineness and the specified fineness is compensated for improved content recognition accuracy of the address label even if the height of parcels is not constant.

摘要翻译：要解决的问题：提供一种读者，其中商业形式被成像，并且其内容基于格式定义被识别，其中成像部分和商业形式之间的距离的波动的影响被抑制。解决方案：在商业形式阅读器中，附着在包裹上表面上的地址标签使用固定在支架上的成像部件20从上方成像。根据包裹的高度波动的实际细度通过对设置在包裹的上表面上的已知尺寸的导板31成像来计算。控制透镜21的变焦系数，使得实际细度与用于识别地址标签的内容的格式定义规定的规定细度一致。利用这种配置，即使包裹的高度不恒定，也可以补偿实际细度和规定的细度之间的差异，以改善地址标签的内容识别精度。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a gradation converting method and its processing program that adjust a file size and image density of outputted image data with binary gradation so as to provide an output of the image with less noise and without blur and deformed characters according to a gradation conversion algorithm that applies binary-coding to a multi-value image. SOLUTION: The gradation conversion method of this invention includes: a step 302 of resetting a binary-coding threshold value to obtain a dense binary image in order to extract thin characters and ruled lines; a step 303 of generating a binary image; a step (No in a step 305) of outputting the binary image when the generated binary image satisfies a limit in a file size or when the generated binary image satisfies a file size limit and the generated binary image satisfies the file size limit and the limit of the file size with respect to the unit area of the binary image; a step 306 of setting a binary threshold α to thin an output density and executing again binary-coding processing when the generated binary image satisfies no condition (Yes in the step 305). The method repeatedly sets the binary-coding threshold until the condition is satisfied to execute binary-coding processing and outputs the binary image when the condition is satisfied.
