    摘要: An air-fuel mixture supplying device for internal combustion engines, in which sonic nozzles are disposed facing each other in such a manner that their center lines lie in the same horizontal and vertical planes so that the fuel ejected from the nozzle is pulverized and mixed with bleed air ejected from the opposing nozzle in optimum condition. During intermittent ejection of fuel, two injector valves inject fuel alternately so that the fuel particles ejected from the opposing nozzles do not collide with each other but only strike against and mix with the bleed air. This eliminates the possibility of fuel particles becoming agglomerated and produces desirable air-fuel mixtures.

    摘要: A projector of a reflection type has a transparent stage plate on which a transparent original sheet is set. A lamp illuminates the original sheet through the stage plate. A Fresnel mirror is laid on an upside of the original sheet, and reflects light from the original sheet in a convergent manner. The light from the Fresnel mirror is reflected away from the stage plate. The light is again reflected, and incident upon a projecting lens, which projects an image of the original sheet to a screen. A housing contains the Fresnel mirror in movable fashion. An inserting slot is formed in the housing, into which the original sheet is inserted during supply of the original sheet. Photo sensors operate to detect a front edge of the original sheet inserted through the inserting slot. It is also detected that the original sheet is set on the stage plate. An ejector switch is operated for ejection of the original sheet. A solenoid shifts the Fresnel mirror up away from a set position in response to a signal from the photo sensors or the ejector switch. The Fresnel mirror is shifted down to the set position in response to a sheet setting signal, to lie on the original sheet. A sheet feeder roller moves the original sheet from the inserting slot to the stage plate during the supply, and moves the original sheet out of the housing during the ejection of the original sheet.

    摘要: An air-fuel ratio control circuit for an internal combustion engine comprising a low-pass filter, a hysteresis type comparator, and delay timer, wherein output signals from an exhaust gas sensor are transmitted through the low-pass filter to the hysteresis type comparator and then to the delay timer. A pulse motor for controlling an air-fuel ratio is driven at high speeds for a specified period of time determined by the delay timer in either forward or reverse direction which is determined by the output of the comparator at each time when the output of the comparator is inverted and is driven at low speeds after the specified period of time has elapsed, wherein the time constant of the low-pass filter is set longer than the delay time of the delay timer.
