Publication number: 20240273320Abstract: A light source is suppressed from being reflected on a workpiece surface of a specular workpiece. A code reading device generates a code image by receiving light specularly reflected from a specular workpiece surface of light emitted from a diffuser and diffusing and reflecting light emitted to a portion corresponding to a code. A position and an angle of the diffuser are fixed with respect to a camera such that the specularly reflected light from the workpiece surface is received by the camera in a state where the camera is in focus on the workpiece surface, and the light source emits the light from the back of a rear end of the diffuser toward the diffuser such that the light source is not reflected on the camera when the camera receives the specularly reflected light.Type: ApplicationFiled: January 10, 2024Publication date: August 15, 2024Applicant: KEYENCE CORPORATIONInventors: Yuta Omura, Kosuke Yanai, Yoshiyuki Fukumoto

Patent number: 8959122Abstract: There is disclosed an interface enabling easy implementation of processing on hierarchical data, and a method facilitating comprehension of the structure, meaning, and format of hierarchical data. There is also disclosed a data processing device including a user interface portion receiving data with tuples each a combination of data of different types, and lists each a series of data of a same type, display data obtained by converting the data, and an instruction requesting processing from a user, and presenting the display data, data managing portion managing the hierarchical data, display-data generating portion generating the display data from the hierarchical data, and analyzing portion implementing the processing. Data is presented in a table format having rows displaying level names and attribute names, respectively. The generating portion samples data of each level of hierarchical data to extract an amount possible to present, and converts the data format.Type: GrantFiled: January 4, 2011Date of Patent: February 17, 2015Assignee: Hitachi, Ltd.Inventors: Kosuke Yanai, Yasutsugu Morimoto

Patent number: 8209297Abstract: For hierarchical data including tuples each including a combination of different data types and lists each listing data of a same data type, corresponding attribute-based data divided by attribute is stored in attribute-based files whereas information on the structure of the hierarchical data is held as schema information. The schema information includes data type information on the hierarchical data structure, including data type information on each element of each tuple and data type information on only a top element of each list. The attribute-based files storing the attribute-based data are managed to be in order by a file name management table. Data on each attribute is stored in a file in a state of being hierarchized in a list format corresponding to the depth at which the each attribute is listed in the schema information.Type: GrantFiled: June 14, 2010Date of Patent: June 26, 2012Assignee: Hitachi, Ltd.Inventors: Kosuke Yanai, Yasutsugu Morimoto, Hisashi Ikeda, Yosiyuki Kobayasi
