摘要： An acoustic lens system is constructed so that at least one surface of acoustic lenses constituting the acoustic lens system is an aspherical surface, which has such a shape that curvature moderates progressively in separating from the axis of the acoustic lens system, and an acoustic beam stop is provided therein. As a result, aberrations can be favorably corrected even when the angle of view and the numerical aperture are increased and this brings about the acoustic lens system suitable for an objective lens of an acoustic system for securing an image of an object having a two-dimensional size in particular.

摘要： The acoustic lens system is used for ultrasonic imaging in an ultrasonic system which displays an image of an object while transmitting ultrasonic waves and receiving the ultrasonic waves reflected from the object, and has a half field angle .omega. expressed as follows: ##EQU1## wherein the reference symbol v.sub.0 represents the velocity of sound in the medium located on the incidence side of the first lens surface and the reference symbol v.sub.1 designates the velocity of sound in the medium located on the emergence side of the first lens surface. Accordingly, the acoustic lens system according to the present invention is remarkably excellent in the performance thereof in respect of field angles, aberrations, aperture angles, attenuation, etc., and has an advantage to permits further reducing acoustic attenuation and preventing spurious images from being formed due to multiple reflections by arranging antireflection films on the lens surfaces.

摘要： A method for producing synthetic gas with which a virtually soot-free synthetic gas having a good composition can be efficiently obtained by a simple device using a liquid biofuel as the starting material, and it is thereby possible to produce a high-quality liquid fuel such as methanol, gasoline or kerosene. Steam and a liquid biofuel produced by pyrolysis of a biomass are fed to the gasification space inside a reactor tube that is not loaded with a catalyst inside the reactor tube and heated to 800 to 1,200° C. from the outside via the reactor tube walls to induce an endothermic reaction and thereby a steam reforming chemical reaction between the steam and the liquid biofuel. By setting the molar ratio of the fed steam and carbon in the liquid biofuel ([H2O]/[C]) at 0.3 or higher, a synthetic gas having a good composition that is virtually free of tar and soot and is primarily H2 and CO is obtained.
