IPC: B41J2/375
Filed: 1990-10-17
Abstract: ABSTRACT   A method and apparatus applicable to a thermal recording system which records data on a recording medium using heat generated by applying power to a resistor.  According to the invention, the resistor itself or a monitor, which is disposed in the path of electric current applied to the resistor, is made of a material having metallic/non-metalic phase transition characteristics at a predetermined temperature, whereby the resistor or the monitor can have the function of interrupting the electric current at the predetermined temperature so that the peak temperature of the resistor is controlled constantly regard-less of the value or period of the applied voltage.  Further, a uniform recording property and a stable continuous tone recording property is achieved by controlling the period for holding the peak temperature of the resistor.

Title: Low flow rate nozzle and spray forming process
Inventor: SAWYER THOMAS F
IPC: C23C4/00
Filed: 1991-08-08
Abstract: RD-19,940 ABSTRACT OF THE DISCLOSURE           An improved nozzle which allows molten metals to be sprayed at low metal flow rates.  This is useful for the Plasma Arc Melting process which used a hearth to prevent ceramic inclusions in the end product.  The new nozzle design avoids metal freeze-off at the nozzle tip because a bore insert is positioned into a standard nozzle.  The bore insert is a conduction heater, e.g., it is fabricated from boron nitride or the like.  In use, molten metal is in contact with the insert so it maintains the insert at about the temperature of the molten metal; this then maintains the nozzle tip at a higher temperature than that of a standard nozzle.  Freeze-off in the nozzle is non-occurring as long a molten metal is in the crucible.

Abstract: A snowshoe binding providing facilitated entry and exit which includes a support housing made of semi-rigid material and having rearwardly extending lateral support arms integral with the support housing to increase lateral support.  The toe binding utilizes a yoke assembly that requires only a single, relatively short strap extending both in the transverse as well as forward direction by the use of a yoke member which permits the strap to remain flat for wearer comfort.  By the use of a modified buckle, the free end of the heel strap extends toward the body so that ergonomic cinching is possible.  Additionally, facilitated attachment and detachment of a crampon without the use of tools is made possible by the particular pivotal arrangement of the toe stop of the toe binding part.
