Patent number: 7243034Abstract: A sensor device according to the present invention has a detection mode for detecting an object W, a first setting mode for changing the output duration of an output signal, and a second setting mode for changing a light-emission period of light emitted to the object W. These modes are switchable by a mode selector switch 12. If a rotary control knob 15 is operated in the detection mode, a CPU 30 changes a setting of a threshold value in response to the operation of the rotary control knob 15 and displays the changed setting of the threshold value on a digital indicator 20. This makes it possible to accurately change settings through relatively simple operations. The rate of change may correspond to the speed of operation of the knob.Type: GrantFiled: July 28, 2005Date of Patent: July 10, 2007Assignee: SUNX LimitedInventors: Masahiro Fujita, Yoji Shibata

Patent number: 5835923Abstract: Publication articles each composed of a headline having relatively high information emphaticality and a text having relatively high information detailednessare coded on an article basis in an information provider apparatus. The coded information is transmitted to a user terminal. The transmitted information is first displayed on a display device of the user terminal in low magnification to display the headlines. The user selects a desired headline. The text corresponding to the selected headline is displayed in a magnification sufficient for making the displayed text legible. The novel setup realizes a publication contents information transmitting/viewing system by which a publication page can be viewed over and each can be read in generally the similar feeling and convenience as those of paper-based publications.Type: GrantFiled: March 14, 1996Date of Patent: November 10, 1998Assignee: Hitachi, Ltd.Inventors: Yoji Shibata, Tetsuro Kiyomatsu, Shingi Domen, Shoji Higuchi
