    摘要： A first reproduced color under signal is delayed by one or two horizontal periods by a delay circuit, and this delayed second reproduced color under signal and the aforementioned first reproduced color under signal have their frequencies converted individually by first and second frequency converters into standard color signals. An oscillatory frequency signals of 2n of carriers for the aforementioned frequency conversions are divided to have the aforementioned carrier frequencies and to produce four carriers having phases of 0, 90, 180 and 270 degrees. These carriers are selectively fed to the first and second frequency converters by switches so that the two frequency-converted signals are subtracted or added in phase or in opposite phase to clear the noise (or crosstalk component), which is caused by the crosstalk between the tracks.

    摘要： An electronic device having a circuit board, a shielding plate disposed thereon and a three-terminal regulator is provided with a heat sink positioned on the outer side of the circuit board and connected to the three-terminal regulator. The heat of three-terminal regulator is radiated from the heat sink, thus making it possible to prevent heating of the shielding plate. In this way, electronic device elements that do not stand up very well to heat, such as an optical pickup unit, can be placed directly on shielding plate, so that the heat of three-terminal regulator is efficiently dissipated and the size of the electronic devices may be reduced.

    摘要： A semiconductor integrated circuit device comprising a logic circuit which is constituted by using tri-state IIL gates. The tri-state IIL gates are particularly arranged to have first and second inputs. If the second input has a first level, the circuit will operate as a normal IIL circuit to provide high and low outputs in response to the first input. However, if the second input has a second level, the circuit will provide a floating output regardless of the first input. The transistors of the IIL circuit can be formed in an island in the substrate, with the potential of the island serving as the second input. In a preferred arrangement, the first level of the second input can be obtained by grounding the island while the second level is obtained by disconnecting the island from ground. These tri-state IIL gates are particularly advantageous to form a transfer gate for an IIL memory similar to the transfer gates used for MOS memories. They can also be used for forming various other logic gate arrangements.
