摘要： The present invention provides methods and apparatus for the formation of a thin noble metal film which can achieve a high rate of film growth, can use inexpensive raw materials, and do not allow any impurities to remain in the thin film. Specifically, the present invention relates to a method for the formation of a thin metal film which comprises the steps of feeding a chlorine-containing raw material gas 55 into an inlet vessel 11 having a perforated plate 12 made of Cu; converting the raw material gas 55 into a plasma; etching the perforated plate 12 with the raw material gas plasma to produce a precursor 13 composed of the Cu component contained in the perforated plate 12 and the chlorine contained in the raw material gas 55; converting hydrogen gas into a plasma; after discharging the precursor 13 from the inlet vessel 11, passing the precursor 13 through a rotating magnetic field so as to cause the precursor 13 to travel toward a substrate 15 in an accelerated manner; and passing the precursor 13 through the reducing gas plasma to remove chlorine from the precursor 13 and directing the resulting Cu ions onto the substrate 15 to form a thin Cu film 62 on the substrate 15, as well as an apparatus for carrying out this method.

摘要： A circuit for forming a vertical synchronizing pulse at the end of a field of a composite video signal utilizes the characteristic of the video signal that the equalizing pulses in the vertical blanking interval have a pulse width one-half that of the horizontal synchronizing pulses in the composite video signal. Accordingly, the circuit includes a discriminating pulse generator which generates a discriminating pulse whose duration ends before the trailing edge of a horizontal synchronizing pulse, but after the trailing edge of an equalizing pulse; a comparator, such as a D-type flip-flop, for comparing the timing of the discriminating pulses with that of the equalizing and horizontal synchronizing pulses to discriminate the equalizing pulses on the basis of such comparison; and a generator for generating the vertical synchronizing pulse in response to the discrimination of the equalizing pulses.

摘要： Color video signal recording and/or reproducing apparatus comprising a first circuit for generating a first signal having the same frequency as the field frequency of the color video signal, and a second circuit for generating a second signal that indicates a field interval having a predetermined phase relationship between a horizontal synchronizing signal and a color subcarrier signal. The first and second signals are combined to form a composite control signal, which is then recorded in a control track on a magnetic tape in the conventional manner. A comparison circuit is included for comparing the composite control signal reproduced from the tape with a reference control signal, the reference control signal being composed of a third signal having a frequency equal to the field frequency and a fourth signal indicating a field interval, in which a phase relationship between a reference horizontal synchronizing signal and a reference color subcarrier signal is equal to the predetermined phase relationship. Thus, during playback the movement of the magnetic tape is controlled in response to the output of the comparison circuit so that the phase of the composite control signal reproduced from the tape coincides with that of the reference control signal.
