Abstract: A first generator is rotationally driven by a rotating shaft of a supercharger to generate power. A second generator generates power and drives an output shaft. A first converter converts alternating-current power generated by the first generator into direct-current power. A second converter always converts alternating-current power generated by the second generator into direct-current power having the same voltage as the direct-current power obtained by conversion through the first converter, or converts the direct-current power obtained by conversion through the first converter into alternating-current power and supplies the alternating-current power to the second generator. An inverter converts the direct-current power obtained by conversion through at least one of the first and second converters into alternating-current power.

Abstract: The present invention provides an image recording apparatus and an excess liquid developer removing device used in the apparatus. In the image recording apparatus, the recording medium wound around the rotary drum is developed by liquid developer supplied from a developing device. A dish provided on the developing device is displaced in the vicinity of the recording medium wound around the rotary drum by being declined in a predetermined angle to prevent the bubbles from generating. The excess liquid developer attached on the recording medium is removed by the air from a nozzle of a blower. The nozzle is displaced by a nozzle displacing device in the vicinity of a developing electrode for supplying the liquid developer only in the midst of developing to prevent the nozzle from being chocked up with toner contained in the liquid developer.

Abstract: Objects of a cylinder cover for diesel engine is to prevent the interference of mists between a plurality of fuel valves, thereby enhancing the spray efficiency, and to prevent troubles of burning of nozzle caused by the collision of mist sprayed from the adjacent fuel valve and increase in thermal stress caused by local overheat of combustion chamber surface due to the collision of mist. To achieve these objects, fuel valves are mounted in a side wall of the cylinder cover so that the centerline thereof is substantially at right angles to the cylinder centerline. Further, the injection angle of the fuel valve is set so as to be an acute angle not larger than 90.degree. to prevent local collision of mist with the combustion chamber wall surfaces, and the volume of the volume portion at the tip of the fuel valve is decreased to the minimum.

Abstract: An object of the invention is to provide a diesel engine of water injecting type having fuel injecting valves and water injecting valves wherein water mists are adapted to reach high-temperature regions of fuel mists so that the temperature can be reduced to inhibit the generation of NOx. In order to achieve the object, the fuel injecting valves and the water injecting valves are arranged separately in different sites, ones in the top wall of the cylinder cover and the others in the side wall, so that high-temperature regions of fuel mists are mixed with water mists in right angles to each other to lower the combustion temperature thereby reducing the generation of NOx.
