    Abstract: A circuit for rectifying and tripling an input voltage from a three-phase source is described. The three-phase input voltage source is connected to the circuit via a wye connected secondary transformer, winding. The center point of the wye connected winding is connected to the midpoint of first and second series connected output capacitors. The other sides of the first and second output capacitors are connected to first and second output terminals respectively. The end of each leg of the three wye connected windings are connected through the second output terminal through a separate reverse biased diode. The end of each leg of the three wye connected windings are also connected through a separate capacitor to the mid-point of separate pairs of two diodes connected in series. One of the diodes of each pair is connected in reverse bias to the mid-point of the output capacitors and the other diode of each pair is connected in forward bias to the first output terminal. Thus, each of the three wye connected windings are connected through circuits including diodes and capacitors and the circuits are connected in parallel across the output terminals to provide a rectified output voltage which is three times the magnitude of the input voltage.

    Abstract: A three dimensional memory using materials switchable from an amorphous state to a crystalline state and back again to its amorphous state is realized by focusing a laser beam into different depths of the material. The material, when in its crystalline state, is capable of generating the harmonic of the frequency of the incident light used to interrogate its state, whereas in its amorphous state it is not a generator of harmonics. The detection of this harmonic allows for increased discrimination in the data reading process.

    Abstract: A metal vapor discharge tube device including a discharge tube and means for introducing a metal or semi-metal into the discharge tube without auxiliary heating. The metal or semi-metal is introduced as a compound of a metal or semi-metal and a nonmetallic radical having a vapor pressure greater than one torr at the temperature of the discharge tube (which for most discharge tubes can be as high as about 300* C). The discharge in the tube causes the decomposition of the compound, thereby releasing the metal or semi-metal into the discharge for excitation. If desired, the excitation can produce lasing and the device may be used as a metal vapor laser.

    Abstract: The disclosure describes an inverter circuit which may be used as a power supply. The circuit includes an even number plurality of transistors connected in series with a source of potential connected to the mid-point of the series arrangement. Each of the transistors has a secondary transformer winding connected across its base and emitter which is coupled to a primary transformer driven by an input signal source. The secondary transformer windings are connected through capacitors to a common point, for example, one end of a DC power supply. A resistor is connected across the emitter and collector of each transistor for uniform static voltage distribution and the transistors are connected in series by separate ones of a set primary output transformer windings connected between each transistor. A ''''poled RC'''' circuit including a diode, a capacitor and a resistor is connected across each transistor for dynamic voltage distribution. A secondary output transformer winding is also included across which an output voltage is produced which in the preferred embodiment may be a square wave voltage.
