Abstract: Intrusion by climbing or jumping over a fence can be detected, and intrusion is detected in a wide area without large-scale equipment. FBGs (grating sections) of different types having different refractive indexes of fiber glass are arranged at predetermined intervals in a longitudinal direction of optical fibers 12, 13A, and 13B, the optical fibers are laid down between poles on the top of a fence or a side thereof, reflected waves from the FBGs are issued by photodetection devices 14, 15A, and 15B in response to an optical input to the optical fibers, and a wavelength shift detection device 16 detects a position of an FBG which exhibits a wavelength shift by swinging of the optical fibers by a stress acting on the fence.

Abstract: The object is to provide a construction method of an information-communicable underground pipe whereby communication cables can be readily laid in an underground pipeline having a main pipe and branch pipes branched therefrom thereby allowing the underground pipeline to be used as an information-communicable underground pipe, and to provide a construction structure and a construction member therefor.

Abstract: A laying method for laying communication cables (16) is provided which allows to lay optical fiber cables (20) in an underground pipeline such as a sewage pipe neither placing direct tension nor allowing slack on them, and for a main pipe in which a plurality of optical fiber cables (20) are to be laid, the method also allows to lay optical fiber cables (20) in the upper space of inside the pipeline and to obviate the need of an expensive robot for the laying operation. In the proposed laying method, a high-strength low-elongation tension member is disposed to be slidable in the lengthwise direction along each optical fiber cable (20, 21, 22), and the tension members (25, 26, 27) are drawn into the underground pipeline (1) to tension the trunk tension member (25) thereby stretching the trunk tension member (25) substantially straight in the underground pipeline (1), and thus the optical fiber cables (20, 21, 22) are laid in the upper space of inside the underground pipeline (1).

Abstract: A break-in detection system includes a detection sensor of an FBG type for detecting an intruder trying to climb over a fence around a premises, and a detection sensor of an OTDR type for detecting an intruder trying to demolish the fence. A fiber optic cable used as a detection sensor has a sensor core wire and a LAN transmission core wire arranged in parallel to form a LAN transmission channel. The LAN transmission core wire transmits videotaped image signals from ITV cameras and image control signals two ways between a monitoring room and an ITV control device. The LAN transmission channel is available for connection by IP telephone sets, a LAN terminal, a wireless LAN terminal, and an IP-BOX for internet communication. The system has excellent reliability and maintenance-free characteristics.

Abstract: A paper refeeding device incorporated in a copier for stacking one-sided paper sheets each carrying an image on one side thereof on an intermediate tray and then refeeding the paper sheets from the tray for forming an image on the other side thereof. In a two-sided copy mode operation, the device reduces the copying time while eliminating paper jam, missfeed and other troubles. The device stacks one-sided paper sheets stably on the intermediate tray and refeeds them without any skew. In addition, the device is simple in construction and implements automatic timing control.

Abstract: An image forming apparatus selectively loaded with a two-side unit and a paper cassette storing a stack paper sheets and selectively operable in a two-sided copy mode and a combined copy mode. The body of the apparatus incorporates at least an image forming section, an image fixing section, a paper transporting section, and a paper discharging section therein. An accommodating section is provided in a lower portion of the apparatus body for selectively accommodating either one of the two-side unit and paper cassette. The accommodating section has a bore open at a particular side where the apparatus is to be operated, and a guide potion for guiding the two-side unit and paper cassette. The two-side unit and paper cassette have the same external configuration.

Abstract: A seat belt storage structure in a hinged seat, in which the hinged seat includes a seat cushion and seat back, each of them being individually hinged such as to be rotatable about their respective hinge points in a forward direction, and there is formed a seat belt storage slit in the seat back, in which slit, the free end of the seat belt is inserted and stored removably. The seat belt storage slit is formed by an inner cloth cell which is attached in a recessed hole of the seat back and further sewn with a covering member of the seat back.
