Abstract: Silicon oxide layers for semiconductor devices with low sensitivity to radiation are prepd. Thus, 0 at 2 l/min was passed over a silicone platelet (surface orientation parallel to (100) crystal plane) heated at 900≦̸C in a tubular oven (diam. 6.35 cm), with simultaneous addition of sufficient H to react with 7% of the 0 present. After 45 min, the H flow was stopped and the 0 was increased to 4 l/min to give an oxide platelet resistant to a radiation dose of 107 rad.

Abstract: A serivice switch is provided for a color television receiver of the type including, in the other named, a black level clamping circuit, a brightness control circuit and an amplifier for coupling luminance signals to an image reproducing line scope. A reserve blanking circuit is coupled with the output of the amplifier for rendering the kinescope in operative during the vertical retrace-horizontal trace intervals to inhibit the formation of disconcerting horizontal trace lines. In a raster position, the service switch is operated to provide a blank raster and to automatically increase the brightness of raster to a level sufficient to permit purity adjustment.

Abstract: A first magnetic field producing member has it poles oriented for producing an initial predetermined movement of the two outside ones of three in-line beams of a cathod ray tube. The second and third field producing members are adjustable for producing variable strength and direction of magnetic fields for moving the two outside beams in opposite and the same directions, respectively, for converging the three beams.

Abstract: A video disc player for playing back prerecorded signals from a spirally-grooved and rotatable record includes a carriage mounted for lateral motion relative to a base plate of the player in correlation with lateral motion of a grooveriding stylus during playback, A stylus arm supported at one end within the carriage carries a stylus at the free end thereof. One end of a leaf spring for urging the stylus into the record groove is secured to the stylus. The second end of the spring is mounted within the carirage above the stylus.

Abstract: The constant current supplier which supplies the current regardless of the variation of temperature or source volt. is consisted of resistors whose resistance value varies as the temperature, avalanche diode connected with the resistor and transistors connected between the resist or and the ground terminal in series. The current maintains constantly in the transistors even when the current varies with the variation of resistance value.

Abstract: A deflection system for a portable TV, which can be operated by AC line voltage or battery, is disclosed, The DC voltage at the first terminal of the horizontal output transformer is equals to the B+ voltage available at the time when the TV is operated by AC voltage, because the horizontal output transformer serves as a step-up inverter when using the battery mode. The step-down transformer available at the time when TV is operated by AC voltage is omitted.

Abstract: A playback system had a rotatably driven-turn table(2) for controlling the operation of a playback sylus device(12). The video information was recovered by sensing the capacitance between the stylusplayback device and the record surface(4). The stylus was supported in a housing (16), and a stylus control device provides movement of the stylus relative to the housing into and out of engagement with the record surface. The first and second drive means have motion coupling devices.
