    摘要： A single phase, full wave diode bridge circuit is connected with a chopper on its DC output side. An output voltage of the chopper is smoothed by a smoothing capacitor and thereafter supplied for a load. A current control apparatus forms a current reference signal which is synchronized with an AC voltage applied to the bridge circuit and has a magnitude corresponding to a current flowing through the load and produces a deviation signal between the current reference signal and an actual AC input current of the bridge circuit. The chopper is controlled in accordance with the deviation signal so that the AC input current follows the current reference signal, whereby the power factor and the waveform of the AC input current in the bridge circuit are improved.

    摘要： A silicone coating material of a vinyl containing polyorganosiloxane, a polyorganohydrogensiloxane, a platinum catalyst, and an amorphous silica powder with a primary particle size of less than 0.2 .mu.m is used to make optical communication glass fiber which has a cross-sectional structure of glass fiber core, a layer of the cured silicone coating material, and the exterior of the silicone coating material being covered with a thermoplastic resin material. The optical communication glass fiber made in this manner has a peelable coating such that the silicone coating material can be stripped from the glass fiber core.

    摘要： In a roller bearing comprising an outer ring which has an inwardly bent annular flange, a sealing ring is loosely interposed the inner circumference of the flange and a shaft with a suitable clearance. An element(s) for imparting a forced rotation to the sealing ring is, also, provided on either one or both of the sealing ring, cage, or the flange of the outer ring to drive the sealing ring by the rotation of the roller, cage or the flange of the outer ring. By virtue of this construction lubricant can be forcibly circulated through the sealing ring between and throughout the interior and exterior of the roller bearing.

    摘要： A system for inserting a reduced picture of a first channel broadcast into a picture of a second channel broadcast on a single screen in a picture-in-picture television receiver. First and second video signal chains are provided. A first group of three memories connects to the first chain for memorizing R, G and B signals obtained from a first field of video signals of the first channel broadcast. A second group of three memories is connected to the first chain for memorizing R, G and B signals obtained from a second field of the video signals of the first channel broadcast. With the disclosed system, picture flicker problems are solved and the horizontal resolution is improved.
