Abstract: A diaphragm actuator having a diaphragm therein which is installed inside a cup so as to form a pressure chamber and a pressure is supplied to the pressure chamber so as to actuate the diaphragm and a rod connected to the diaphragm. The rod is supported by a bearing disposed inside the cup so that the diaphragm actuator is excellent in thermal insulation against the surrounding atmospheric temperature, thus preventing the diaphragm from being thermally deteriorated. To achieve this end, the bearing is extended to an inner peripheral surface of the cup until it touches the inner peripheral surface, and a contact surface of the bearing with the rod is formed in an arc-shaped section having the least inner diameter at its axial center.

Abstract: A map display unit is provided with a set uni that sets a rule for extracting map information from a storage device. The set unit sets a first rule for most preferentially extracting map information on the largest scale and a second rule for most preferentially extracting map information on a specified scale. For this reason, if the first rule is set, a map on the largest scale having detailed information can be displayed, even if a map were switched. Therefore, the accuracy of route guidance can be enhanced by displaying a map suitable when passing through complicated geographical features or city. On the other hand, if the second rule is set, an arbitrary scale can be specified. For example, if a map on the smallest scale is specified, it can overlook a wide range of area and therefore the entire planed route can easily be grasped.

Abstract: A group of maps corresponding to the present position detected by a position detection unit is retrieved from a storage unit. Also, a map on the same scale as a map being displayed is extracted from the retrieved group of maps. If there is an overlapped portion between the extracted map and the map being displayed, they are displayed with the overlapped portion held. With this, both the map being displayed and the extracted map can be displayed as if they were continuous to each other, and the present-position mark can be displayed without being jumped considerably.

Abstract: An optical illumination device reflects and condenses light from a mercury-arc lamp by a light reflecting and condensing member and then reflects and deflects the light, thereafter the reflected and deflected light is transferred to a relay-lens system through a collimator lens or input lens, band-pass filter and fly-eye lens. Gas from which impurities are removed by a filter is flown around optical elements to separate the optical elements from air containing material causing clouding of the optical elements to thereby restrain clouding of the optical elements. On the other hand, or in addition, the reflectance of the light reflecting and condensing member and/or miller for the light of the absorption band of sulfur dioxide is made small to prevent the optical elements from clouding.
