    摘要： In a video tape recorder of the helical scan type, a pair of rotary magnetic heads for the audio signal are provided in addition to the rotary video heads so that the audio signal is recorded on the same slant track as of the video signal on a multiplex basis. The audio head pair is provided with an azimuth angle with opposite polarities from each other and different in value from that of the video head pair. The system has a first operation mode of the standard tape speed and a second operation mode in which the tape is fed at a speed, for example, 1/3 the standard tape speed. The audio and video head pairs are disposed on lines intersecting at right angles with an offset of T.sub.1 /2+T.sub.1 provided in the axial direction of rotation between the two magnetic head pairs, where T.sub.1 is the track pitch of the recording track formed on the tape in the second operation mode. The system produces overlapping tracks for the audio and video signals on the magnetic tape. In the first operation mode, the recording track is formed by a combination of magnetic heads providing an increased difference of azimuth angles between the audio and video heads, while in the second operation mode, the track is formed by a combination of magnetic heads providing a decreased difference of azimuth angles between the audio and video heads.

    摘要： In a FM luminance signal circuit of a signal reproducing circuit of a video tape recorder,(a) a reproduced signal is up-converted by an up-converter, the up-converted signal is divided into two frequency components by a surface acoustic wave filter having a first filter for peaking a high frequency component and a second filter for peaking a low frequency component, a limiter connected to the first filter, an amplifier connected to the second filter, and an adder of an output of a limiter and an output of an amplifier, and the reversal of the levels of the FM carrier signal and side band signal is prevented by above configuration.(b) A side-band glass delay line of 1H (one horizontal scan period) is provided to get 1H delayed luminance signal. Using main luminance signal and 1H delayed luminance signal, a line correlation circuit and a video dropout compensation circuit are realized.(c) In a PAL signal reproducing circuit, where a chrominance signal is delayed by 1H by a comb filter using 2H delay line, 1H delayed luminance signal is used to prevent a chrominance displacement from the luminance signal.

    摘要： A filter integrated circuit having a reference level generator circuit for attenuating its input signal and generating a reference level signal, a pseudofilter circuit including resistors and a variable capacitor as filter elements, and an error amplifier unit for comparing the level of the output signal of the reference level generator circuit with the level of the output signal of the pseudofilter circuit and for generating an automatic adjustment control signal in accordance with the level difference between the output signals. The automatic adjustment control signal is supplied to the pseudofilter circuit to change the capacitance value of the variable capacitor in the pseudofilter circuit so that the output signal level of the pseudofilter circuit may become equal to the level of the reference signal. The automatic adjustment control signal is also supplied to at least one filter circuit to change the capacitance of a variable capacitor included therein. As a result, the deviation in the filter characteristics caused by deviations in the resistance of a resistor and in the capacitance of the capacitor is corrected.

    摘要： A tritium removal device for a lithium loop comprises a neutron source (1) for colliding proton on a lithium flow, thereby generating neutrons, a lithium tank (11) for letting the lithium passing through this neutron source (1) to flow into through a flow passage (9), thereby for temporality accumulating it therein, and a lithium pump (17) for circulating and supplying the lithium of this lithium tank (11) to the neutron source (1) through a supply-side flow passage (9′). The lithium tank (11) and the lithium pump (17), into which hydrogen gas containing tritium therein can be easily collected, are enclosed within a hermetically sealed container (7) including an inactive gas therein, so that even if the hydrogen gas including the tritium therein is leaked into the hermetically sealed container (7), it is removed by a hydrogen isotope removal filter. It is possible to remove the tritium, with safety, without diffusing the tritium from an inside of the lithium loop for forming a target flow into an atmosphere.

    摘要： An object of the present invention is to efficiently produce ultrafine particles having such a small diameter as 50 nm or less, a narrow range of size distribution, and a non-oxidation surface. According to the present invention, the metallic ultrafine particles are produced by dropping a raw metallic powder onto a controllably heated evaporating surface in a decompressed inert gas; instantly evaporating the raw metallic powder to form the ultrafine particle; and condensing and depositing the ultrafine particle on a trapping surface arranged above the evaporating surface. The raw metallic powder is any one of a single metal, an alloy and an intermetallic compound, preferably has an average particle diameter controlled to 500 μm or smaller so that the powder can be instantly evaporated, and is preferably supplied by a minute amount.
