    摘要: A diesel engine has a cylinder head, an auxiliary combustion chamber defined in the cylinder head, an atomization passage communicating with the auxiliary combustion chamber, and a fuel injection nozzle means mounted in the cylinder head and having a primary injection port opening into the auxiliary combustion chamber and a secondary injection port opening toward an inner wall surface of the atomization passage. When the diesel engine is under a low load, fuel is injected from the secondary injection port toward the inner wall surface of the atomization passage while fuel is prevented from being injected from the primary injection port, for thereby causing fuel to flow along an inner wall surface of the auxiliary combustion chamber, which is positioned downstream in the direction in which a swirl flows.

    摘要: A signal processing device for selectively producing as an output signal either a signal corresponding to an input signal r a signal which may be a fixed voltage level for muting purposes or a mixed signal. A current switch composed of pairs of differential transistors switches Among a plurality of current paths in accordance with a difference between the voltage levels of a pair of input signals varying in level in phase opposition to each other, or in accordance with a difference between the voltage levels of a reference voltage and a signal phase input signal. A load circuit composed of a plurality of resistors is connected in series with one of the current paths. A current bypass forming circuit which forms a current bypass of a constant current at a desired timing corresponding to a pulse signal with respect to the current path forming the load circuit effects the generation of an output signal not corresponding to the input signal, that is, a fixed voltage for muting the mixed signal.

    摘要: A driving mechanism for driving a moving handrail of an escalator and the like. The driving mechanism include driving rollers and guiding rollers which are disposed to confront with each other through the moving handrail interposed therebetween. The driving rollers are secured to a movable plate, while the guiding rollers are attached to fixed plates. The movable plate is adapted to be moved in the direction perpendicular to the moving handrail, while the fixed plates are firmly secured to a part of a truss frame which supports the escalator. The movable plate carries a sprocket by means of which the driving rollers are rotated to drive the moving handrail. The sprocket itself is adapted to be driven by a chain going therearound. The vertical component of the tensile force residing in the chain acts to press the driving rollers onto the moving handrail.
