Abstract: An information processing apparatus is disclosed which comprises: an inputting element for inputting a departure point and a destination; a nearby station retrieving element for retrieving stations located near the departure point and the destination which were input through the inputting element; a train route searching element which, if there are a plurality of stations near at least either the departure point or the destination, the nearby stations having been retrieved by the nearby station retrieving element, then searches for at least one train route for each of all nearby station combinations linking the departure point to the destination; a storing element for storing the train routes retrieved by the train route searching element; a setting element for setting prioritizing conditions to be referenced when the train route searching element searches for train routes; and a ranking element for ranking the train routes stored in the storing element in accordance with the prioritizing conditions set by th

Abstract: There is provided an information processing apparatus in which when a route to a destination is searched, a road of the route is displayed with emphasis while a color or shape indicating the type of the road can be checked. When the route to the destination is searched, both sides of the road of the searched route are displayed with emphasis lines. The inside of both the sides of the road is displayed such that the type of the road, such as an expressway or an open load, can be recognized. By this, a user can easily check the searched route, and can check the type of the road of the route. For example, in the route from a current location to a destination, the user can check that a route A is an expressway, and other route B, route C, and route D are open roads.

One of these redundancy systems provides an operating connection between each of the office transmitters which are connected to the office transceivers and each of the subscriber transmitters which are connected to the subscriber transceivers.

Abstract: A plurality of dielectric plates are disposed side by side to form a dielectric plate assembly and matching layers are respectively disposed adjacent to both end faces of the dielectric plates. A plane wave is incident on one of the matching layers perpendicularly thereto and passes through the dielectric plate assembly and are emitted from the other matching layer. Ratios b/a and a/.lambda..sub.0 (a being the distance between the centers of adjacent ones of the dielectric plates, b the thickness of each dielectric plate and .lambda..sub.0 the free space wave length of the electric wave) are selected so that the frequency characteristics of the phase difference between the electric field components of the plane wave respectively perpendicular and parallel to the dielectric plates, which are produced by the passage of the plane wave through the dielectric plate assembly, has a value of 90.degree. at two different values of a/.lambda..sub.0.
