    摘要： An antenna (80,90) has a one dimensional or multidimensional array of elements (20,40), wherein spacings between successive elements of at least part of the array are non periodic and correspond to a series of multiples of a unit spacing, the multiples following a Fibonacci sequence. Two dimensional arrays can be arranged as a Fibonacci grid or as a Fibonacci square tiling. The number of elements can be reduced for a given measure of resolution, while still enabling the signal being transmitted or received to have a peak in a single unique direction and thus form a beam. Furthermore, since there will be some elements clustered close together and a few which are well spaced, it can be more suitable for vehicles (30) than a regularly spaced array. It can be used as a transmit antenna or as a receive antenna for a submillimeter radar system.

    摘要： A compression-ignition type engine in which first fuel of an amount of not more than 30 percent of the maximum amount of fuel is injected in an injection timing region from about 90 degrees to about 20 degrees before top dead center of the compression stroke, then second fuel is injected at substantially top dead center of the compression stroke. When the intensity of engine vibration becomes larger, the first injection amount is made to be reduced.

    摘要： A compression-ignition type engine in which the engine operating region is divided into a first operating region F of a low load side and a second operating region G of a high load side. When the engine operating state is in the first operating region F, fuel is injected just once before 50 degrees before top dead center of the compression stroke. When the engine operating state is in the second operating region G, first fuel injection I.sub.1 of an amount of not more than 30 percent of the maximum amount of fuel is performed in an injection timing region II and second fuel injection I.sub.2 is performed at substantially the top dead center of the compression stroke.

    摘要： A compression-ignition type engine in which fuel is injected in a combustion chamber during the compression stroke or intake stroke before 60 degrees before top dead center of the compression stroke and in which the mean particle size of the fuel injected at that time is made a size in which the temperature of the fuel particles reaches the boiling point of the main fuel component, determined by the pressure in the combustion chamber, at substantially the top dead center of the compression stroke. After the injection and until about the top dead center of the compression stroke is reached, evaporation of the fuel by boiling from the fuel particles is prevented and the fuel of the fuel particles boils and evaporates and fuel is ignited and burnt after about the top dead center of the compression stroke.
