摘要： A plurality of array antenna elements are divided in terms of a set constituted of an optionally selected L number of groups. The spaces between the array antenna elements are determined by obtaining a greatest common divisor of the set as a greatest common divisor of inter-group element spaces, the set having, as components, greatest common divisors of inter-element spaces of the individual L number of groups in the set, obtaining a greatest common divisor of inter-group element for every number L equal to or less than the maximum number of incoming waves by changing the number L of group components, and allowing a direction not to be caused in the radar scanning region by a number equal to or more than L+1, on the basis of the greatest common divisor of inter-group element spaces for every number L of group components, the direction being linearly dependent on an incoming wave corresponding to the greatest common divisor of inter-group element spaces.

摘要： A vehicle drive control apparatus for use in a vehicle collects the number of travels in each of road sections in a traveled route for each of travel directions, extracts road sections having been traveled for more than a threshold number for each of travel directions, and stores extracted road sections as control section data maps in a durable storage medium. If the vehicle travels into the road sections stored as the control section data map, the “stored-as-the-map” road sections are identified as a series of road sections of high-travel-probability. In this manner, a series of road sections can be accurately identified as a high-probability section without having a user input of a travel destination or the like.

摘要： In a mesa type PIN-PD formed using a heavily doped semiconductor material, a high frequency response is degraded as slow carriers occur in a heavily doped layer when light incident into a light receiving section transmits through an absorbing layer and reaches the heavily doped layer on a side near the substrate. In a p-i-n multilayer structure, a portion corresponding to a light receiving section of a heavily doped layer on a side near a substrate is previously made thinner than the periphery of the light receiving section by an etching or selective growth technique, over which an absorbing layer and another heavily doped layer are grown to form the light receiving section of mesa structure. This makes it possible to form a good ohmic contact and to realize a PIN-PD with excellent high frequency response characteristics.
