Abstract: An information exchange system is capable of realizing useful information exchange both for the service provider located along the road and providing services and the vehicular driver, by effectively using limited communication capacity of the road-vehicle radio communication. The information exchange system has a vehicle-mounted unit and a road-side unit providing information to the vehicle-mounted unit using a road-vehicle radio communication. The vehicle-mounted unit includes receiving unit receiving information transmitted from the road-side unit through a radio communication and transferring unit transferring at least a part of a content of the received information to a vehicular occupant. The road-side unit including storage unit storing information to be transmitted to the vehicle-mounted unit and transmitting unit transmitting information to the vehicle-mounted unit through the radio communication.

Abstract: A surveillance camera system includes a photographing lens system, and a camera body to which the photographing lens system is detachably attached. The camera body includes a color imaging device on which an image formed by the photographing lens system is formed. The correcting of aberrations is carried out in a photographing lens system so that the difference between (1) the in-focus position at which the maximum MTF characteristic in the visible light wavelength range of about 400 nm to 700 nm is obtained and (ii) the in-focus position at which the maximum MTF characteristic in the near-infrared light wavelength range of about 700 nm to 1000 nm is obtained is less than 10&mgr;m.

Abstract: A fuel tank-mounting structure for a portable power working machine, which has an internal combustion engine as a power source and a fuel tank received in a tank housing portion defined in a two-piece cover housing of the power working machine, includes cushioning members supporting the fuel tank in the tank housing portion of the two-piece cover housing. The cushioning members are interposed in spaces between the tank housing portion and all faces of the fuel tank, namely, the front and rear end faces, the right and left side faces, and the top and bottom faces of the fuel tank. The cushioning members prevent the vibration of the internal combustion engine from being easily transmitted to the fuel tank, thereby avoiding the generation of bubbles in the fuel as well as damage to the fuel tank, and also reduce the manufacturing cost of the fuel tank-mounting structure.

Abstract: In an advanced-cruise-assist highway system, an AHS center facility, which is an upper facility for on-road facilities, periodically receives diagnostic information from the on-road facilities, and when it is determined that any on-road facility is in the faulty state, communicates the information that the on-road facility is in the faulty state to on-road facilities upstream from the faulty on-road facility, and the on-road facilities having received the information on the fault in the downstream on-road facility communicates the information that the downstream on-road facility is in the faulty state via a road-to-vehicle communication facility to AHS vehicles having the possibility of entering a zone under control by the faulty on-road facility. Further the information that the downstream on-road facility is in the faulty state is displayed on information board which can be recognize by vehicles having the possibility of entering a zone under control by the faulty on-road facility.

Abstract: A traveling support information processing unit which can prevent willful assessment of information by a device installed on a road or loaded in vehicle and makes it possible for the device to always issue a demand for acquisition of required information according or a demand for consultation for cooperated determination, and which does not required any specific and additional device for acquisition of positional information for each vehicle and also can improve safety and efficiency in road utilization.

Abstract: An image data conversion processing device including an issue unit, plural line storing units and a generating unit for converting to a television signal image data stored in plural kinds of developing formats in a storing unit. The image data comprises plural lines, and the television signal comprises a predetermined number of lines. The issue unit issues a transmission instruction of image data to the storing unit in accordance with a period specified by a ratio of the number of lines of the image data to be converted and the number of lines of the television signal. The plural line storing units cyclically store the image data transmitted from the storing unit line by line on the basis of the transmission instruction of the issue unit.

Abstract: A vacuum apparatus has a recessed portion which is provided at an appropriate position of a fan casing. When incoming materials frequently pass through the fan casing, the recessed portion wears more quickly than the rest of the inner surface of the fan casing. Hence, a user of the vacuum apparatus can easily know when to replace the fan casing by visually checking the recessed portion from outside the fan casing.
