Abstract: A fuel feed apparatus of an internal combustion engine comprises: a passage member which is formed with a fuel passage serving to direct fuel injected from a fuel injection valve toward respective intake valves of the internal combustion engine, assist air passage through which assist air is jetted so as to cross the fuel injected from the fuel passage, and a cylindrical guide portion serving to regulate a spray cone angle of the fuel when the assist air is jetted from the assist air passages; and an interrupter device for interrupting the supply of the assist air to the air assist passages in accordance with the operating condition of the internal combustion engine, so that sprays of fuel directed to the plurality of intake valves individually are formed by the fuel passage when the interrupter device cuts off the assist air, while a single spray of fuel atomized by the assist air the spray cone angle of which is regulated by the guide portion is formed when the interrupter device allows the assist air to be

Abstract: In a fuel supply device for vehicles, a sub-tank is arranged within a fuel tank. At least one intake port is provided in a bottom wall of the sub-tank. A check valve is arranged at the intake port. A fuel pump is arranged within the sub-tank to supply fuel from the sub-tank to an engine. A fuel return pipe is provided through which a part of the fuel supplied through the fuel supply pipe is returned into the sub-tank. A jet pump is connected to the fuel return pipe so as to deliver the fuel within the fuel tank into the sub-tank through at least one suction port of the jet pump by using fluid energy of the fuel returned into the sub-tank. A pipe is connected to a fuel discharge port of the jet pump, and extends to an upper location within the sub-tank. The jet pump is constituted by a groove forming a flat fluid control device arranged between the fuel pump and the bottom wall of the sub-tank. The groove is formed therein with the fuel suction port and the fuel discharge port of the jet pump.

Abstract: Five color television cameras take pictures of an object. A video signal from the central camera is transmitted by circuitry substantially the same as the circuitry used in existing color television system. The video signal is subtracted from four video signals from the other cameras, two located on the left side of the central camera and the remaining two on the right side thereof, thus generating four video difference signals. A carrier wave is used of frequency 1/n (n is an integer) of the color sub-carrier frequency, and placed within the lower sideband of the reference frequency of an assigned channel. The spectrum distribution of the wave remains in interleaving relation with the spectrum distribution of a luminance signal from the central camera. The carrier wave is divided into two-phase carrier waves. Each of these carrier waves is divided into a positive halfwave and a negative halfwave.

Abstract: A process for producing meat cured products having antibotulinal activity, which comprises separately adding to meat ascorbic acid or its salt and/or erythorbic acid or its salt in the form of a powder or aqueous solution and (B) a nitrite salt in the form of a powder or aqueous solution.

Abstract: A stereoscopic color television system in which operation of a plurality of color television cameras photographing the same object is switched over in turn per period of a color synchronization subcarrier to send forth video outputs from the plural color television cameras in succession. A stereoscopic color television picture tube includes a lenticular lens assembly whose lenticular lenses are each formed with an equal width to the horizontal pitch of apertures of a shadow mask or meshy focusing grid, and which is positioned between the shadow mask and face plate and also provided with a phosphor screen on the focal plane of the lenticular lens assembly, the phosphor screen being formed of a plurality of sets of red, green and blue phosphor stripes formed with an equal width to the vertical pitch of apertures of the shadow mask or meshy focusing grid. The color television picture tube further includes vertically arranged red, green and blue electron guns.
