    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: A socket for the inspection of semiconductor devices is disclosed which has laterally extended leads. The device is mounted in a mounting seat of the socket body and results in improvement of the inspection process because difficult steps such as soldering can be omitted. The socket is composed of a socket body which is mountable on a circuit board having a mounting seat therefor, a lead frame intervening between the socket body and the circuit board and an anisotropically electroconductive elastic connector sheet.

    摘要: In an image forming apparatus having a charging member for charging a photoconductive element in the form of a drum or a belt in contact therewith, a cleaning member cleans the surface of a charge roller contacting the photoconductive element. The cleaning member is usually spaced apart from the surface of the charge roller, but the former is caused to contact the latter only for a predetermined period of time at predetermined intervals. This frees the charge roller from excessive cleaning due to the cleaning member and, therefore, obviates defective images. The time for causing the cleaning member to contact the charge roller may be changed on the basis of the degree of contamination of the charge roller in order to cope with accidental smears brought about on the charge roller.

    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.
