摘要： A simulation method for imaging of an underwater object is performed by simulating the object with a test panel having several strips of different brightness, and irradiating the test panel with a pulsed laser beam having three primary colors. From the reflected beam pulses, contrast values of the test stripes are computed for reflected pulses of each color in relation to the turbidity and visibility distance. The method may be used in conjunction with an imaging apparatus having a laser generation device which produces three primary colors of three different wavelengths; a laser beam detection device to receive the reflected beam pulses of respective primary colors, to determine intensities of the reflected beam pulses of respective primary colors, and to output three primary color signals to an image monitoring device. The imaging system may also be arranged so that a laser irradiation device, a laser beam detection device and an image monitoring device are all placed underwater in a submersible vessel with appropriate provisions for hydrostatic pressure and unmanned operation.

摘要： Described herein is a combustion chamber for internal combustion engine, including a protuberance extending radially inward from a peripheral wall surface of a combustion chamber which is formed by hollowing the top of a piston in the axial direction thereof. The protuberance induces rolling streams turning in the same direction as the fuel swirl thereby collecting air and atomized fuel in a region on the upstream side of the protuberance. The rolling stream serves to improve the ignition quality by enriching the concentration of fuel vapors in that locality. The flames generated in the vicinity of the protuberance are propagated to the atomized fuel which is supplied to other regions of the combustion chamber, thereby providing an internal combustion engine with improved ignition and combustion qualities.

摘要： A method of heterogeneous reaction is described, comprising reacting a water-soluble component and an oil-soluble component dispersed in the water-soluble component or an aqueous medium containing the same. This dispersion is attained by passing the oil-soluble component through the micropores of a hydrophilic material as it is introduced into the aqueous medium. This hydrophilic material can be shaped into a desired form such as a membrane and a fabric. The flow rate, reaction rate and conversion are easy to control in the present method since the particle size of the oil-soluble component can be appropriately controlled. Furthermore, the present method does not need any stirring power nor an emulsification operation, and thus is advantageous from an economic standpoint.

摘要： A combustion chamber for an internal-combustion engine of the direct fuel injection type using a volatile fuel having a low cetane number, such as alcohol. The combustion chamber comprises a main combustion chamber and an auxiliary combustion chamber which are formed in the crown of a piston so as to overlap each other and so that individual swirls of intake air are formed therein, respectively. The fuel highly atomized for quick evaporation is supplied to the auxiliary combustion chamber and fuel films are formed over the respective inner surfaces of the main and auxiliary combustion chambers for being vaporized by the heat of the walls of the main and auxiliary combustion chambers. Thus, the combustion chamber has excellent combustion characteristics, in which the air-fuel mixture is reliably ignited in the entire range of loaded operation of the engine, combustion noise and vibration are reduced, and the discharge of unburned substances is controlled.

摘要： According to the present invention, main and subcombustion chambers into which fuel is fed directly in an atomized state and in each of which a swirl is formed, are formed in communication with each other in a top portion of a piston, in order to use not only gas oil but also other volatile fuels of low cetane number such as gasoline and alcohol. Further, in order to improve the combustion performance, fuel is supplied into the subcombustion chamber in a finely pulverized state for easier evaporation, and fuel is adhered as liquid films to the main and subcombustion chambers. By so doing, ignition is ensured in all load conditions and it becomes possible to effect evaporation and combustion on the wall surface of each combustion chamber. Consequently, it is possible to obtain a combustion performance which is low in combustion noise and vibration and also low in the formation of unburnt matter.
