    • A color display with a white balance self-adjusting function, including a DC-voltage-level/gain adjusting circuit for adjusting, on the basis of adjustment data, the DC voltage level and the gain of each of R, G and B primary color signals, thereby outputting the adjusted signals. Also includes is a CRT driving circuit responsive to the output signals of the DC-voltage-level/gain adjusting circuit for outputting CRT driving signals to drive the color CRT of the display, and a cathode current detecting circuit for detecting currents flowing through the cathode electrodes of the color CRT. Further a micro-controller for applying black and white reference level voltages, at predetermined points of time, to the DC-voltage-level/gain adjusting circuit to perform adjustment, comparing detection values from the cathode current detecting circuit, with preset reference values, generating data on the basis of the comparison results, storing the generated data in the non-volatile memories, and reading and supplying the stored data as adjustment data to the DC-voltage-level/gain adjusting circuit is included.

    • An internal combustion engine includes a cylinder head having a pair of upright intake ports formed therein on opposite sides of a plug hole extending along a cylinder axis, and each intake port has an upstream-side upright part extending from the top face of the cylinder head along the cylinder axis and a downstream-side slanting part having an intake opening communicating with a combustion chamber on one side of an imaginary plane containing the cylinder axis. An upper opening of each intake port opening in the top face of the cylinder head has a peripheral edge extending along the peripheral edge of an upper opening of the plug hole, and the peripheral edge of the upstream-side upright part extends along the outer surface of a lash adjuster. When viewed in vertical section along the imaginary plane, the upstream-side upright part extends obliquely downward from the top face of the cylinder head in a direction away from the lash adjuster, and the downstream-side slanting part approaches the plug hole with decrease in distance to the combustion chamber and then extends parallel to the plug hole. The downstream-side slanting part, when viewed in vertical section perpendicular to the imaginary plane, extends away from the cylinder axis with decrease in distance to the intake opening. With the intake ports having the above overall shape and sectional shape, each intake port can be given a required cross-sectional area without increasing the dimensions of the engine, and makes it possible to form a proper intake air flow inside the combustion chamber.

    • A stratified combustion engine provided with a prechamber having no inlet valve associated therewith, wherein the precombustion chamber comprises a first chamber communicating with a main combustion chamber, a second chamber communicating with the first chamber only through an orifice, and a discharge electrode disposed in the orifice. In the suction stroke, a lean fuel-air mixture is charged into the main combustion chamber, while a stream of a rich fuel-air mixture, which is deflected in the direction of flow by impinging against the back face of an inlet valve, is introduced into the first chamber from the main combustion chamber through a communication passage, so that the so-called stratified charge can be achieved. In the compression stroke, the rich fuel-air mixture is charged from the first chamber into the second chamber through the orifice. In the combustion process, the rich fuel-air mixture existing in the orifice is ignited and the fuel-air mixture in the first chamber is burnt by the flame emerging continuously from the second chamber through the orifice so that the lean fuel-air mixture in the main combustion chamber can be burnt by the flame of the rich mixture burning in the first chamber.
