    摘要： A high-pressure valve is disclosed having a cylindrical chamber disposed in a valve body with an inlet and four outlet ports. The cylindrical chamber has a cylindrical valve core rotatably mounted therewithin. The core has three communicating passageways having a Y-shaped configuration. The axis of the passageways, outlets and inlet lie in a common plane perpendicular to the axis of the chamber. The passageways are disposed so that they can simultaneously communicate with the inlet and two outlets, the outlets being disposed at angles to said inlet and having crosssectional areas such that the vector forces on said core caused by the fluid pressure is essentially zero.

    摘要： A vacuum evaporation and product thereof process useful for growing large surface area films useful as laser crystals comprising, during the growth process, heating a substantial portion of the reaction chamber interior surfaces to a temperature greater than the temperature of the substrate growth surface while drawing a vacuum on and controlling the rate of flow of vapor from the reaction chamber to a slow flow to prevent disproportionate loss of the higher vapor pressure elements through deposition onto the reaction chamber surfaces and exit from the reaction chamber to maintain a nearly stoichiometric mixture of the vapor in the reaction region adjacent the growth surface.

    摘要： Magnetic signals from a master magnetic recording medium are duplicated onto a copy magnetic recording medium by utilizing an intermediate comprising two magnetizable materials, one having low Curie temperature Tc and high Hc relative to the Hc of the copy medium and the other having relatively high Tc and low Hc relative to the Hc of the master medium. In one embodiment utilizing an endless belt intermediate, the signals are (1) copied from the master medium onto a high Tc layer of the belt by magnetically stimulated contact duplication, (2) transferred from the high Tc layer to a low Tc layer of the belt by thermoremanent contact duplication, and (3) copied onto the copy medium by magnetically stimulated contact duplication.
