An oil pump apparatus includes a body, a first rotor and a second rotor disposed in the body so as to be able to rotate and a regulator valve mechanism for regulating the pressure of oil discharged to portions of an engine, wherein the regulator valve mechanism is disposed in the inside of the body and the engine and includes a regulator valve member which moves in the direction being in parallel with a rotation as of the first and second rotors in response to the discharged oil pressure.
摘要:
A color signal processor in which a color subcarrier is multiplied with either a signal harmonic or a phase shifted harmonic of a low frequency chrominance signal, depending on whether the R-Y axis of the chrominance signal is inverted. Band pass filtering extracts an arithmetic carrier signal resulting from the multiplication. The low frequency chrominance signal is multiplied by the extracted arithmetic carrier, and band pass filtering removes both upper and lower side band components generated in accordance with the low frequency chrominance signal multiplication. Various configurations of the above invention eliminate the need for a circuit inverting the R-Y axis, simplifying the structure of color signal processors and related devices. In addition, since no resonating circuit is used, the invention can be effectively implemented in an integrated circuit.
