摘要:
A glow plug having a hollow cylindrical metal shell, an axial electrical terminal, and a heater member protruding externally from the shell. The heater member has a surface film heater element disposed on at least one surface of an electrically nonconductive cylindrical substrate. Electrical connections between the heater element, the shell and the axial electrode are made by conductive surface films. A first conductive surface film disposed on the external surface of the cylindrical substrate makes electrical contact with the shell. A second conductive surface film disposed on the internal surface of the cylindrical substrate makes electrical contact with the axial electrical terminal. The heating element is preferably a transition metal surface film which catalytically reacts with the air/fuel mixture to enhance combustion at lower temperatures. The thermal response time of the surface film heater element from ambient to an operating temperature exceeding 800.degree. C. is less than 5 seconds.

A method for automatically updating persistent boot parameter storage in a computer system includes storing updated boot parameters for an operating system in the computer system in a hardware boot parameter storage area in a memory of the computer system; performing a reboot of the operating system with the updated boot parameters; determining whether the reboot of the operating system is successful; and, in the event the reboot of the operating system is successful, automatically propagating the updated boot parameters from the hardware boot parameter storage area to a persistent boot parameter storage area.

System-managed duplexing of coupling facility structures. A plurality of instances of coupling facility structures are maintained in a plurality of coupling facilities. Duplexing processing associated with the plurality of instances is managed by one or more operating systems, making many of the steps associated with duplexing transparent to the exploiters of the coupling facility structures. System-managed duplexing provides high availability for coupling facility structure data via a robust recovery mechanism (i.e., duplexing failover).

Cache structures of a shared storage processor of a computing environment are copied. A copy operation for a cache structure of the shared storage processor is initiated. Although the cache structure is owned by an exploiter of the cache structure, one or more objects of the cache structure are copied via an operating system of the computing environment. The one or more objects are copied from the cache structure to another cache structure of the computing environment. Both cache structures may be located within the same shared storage processor or within different shared storage processors.

List structures of a shared storage processor of a computing environment are copied. A copy operation for a list structure of the shared storage processor is initiated. Although the list structure is owned by an exploiter of the list structure, one or more objects of the list structure are copied via an operating system of the computing environment. The one or more objects are copied from the list structure to another list structure of the computing environment. Both list structures may be located within the same shared storage processor or within different shared storage processors.

An electro-mechanical fuel injector comprising: a housing and valve seat including a valve setting surface and a metering orifice disposed at a lower end of the housing. An armature assembly is movable relative to the valve seating surface for opening and closing the metering orifice and includes an armature and a pin extending therefrom and adapted to engage the seating surface; a coil assembly and spring are provided to move the armature assembly in a direction to open and close the metering orifice. The injector includes a fluid chamber defined upstream of the metering orifice, in surrounding relation to a portion of the armature assembly. A damping assembly is also provided, movable with the armature assembly, for generating a viscous shear damping force by interacting with the wall of the chamber.

A high pressure vortex fuel injector comprising a hollow housing or body including a plurality of passages at least one of which is adapted to receive fuel through an inlet. The injector also includes a passage for guiding the piston into seating relationship with the valve seat to control the flow of fuel through the metering orifice and a solonoid assembly for moving the piston relative to the valve seat. The injector further includes a swirl or vortex chamber, to angularly accelerate the fuel, formed in cooperation with the first surface of the valve seat. The injector additionally includes passages for permitting fuel to circulate about an electric coil thereof, thereby cooling same during instances when the metering orifice is closed. The injector further includes passages within the swirl chamber for assisting in the rapid formation of a conical spray pattern upon the opening of the metering orifice.
摘要:
A pressure sensor including a pressure capsule such as a dual diaphragm quartz capacitance pressure capsule. The pressure capsule having two parallel quartz plates spaced by a dielectric ring forming a vacuum chamber therein.A registration fixture is described which contains a plurality of flat plates, each plate having a pressure capsule receiving cavity sized to closely receive one of the quartz plates and further provides a uniform temperature radiation pattern for sealing of the pressure capsule during the controlled pressure-temperature profile.

A system and method for detection of and a policy directed resolution of signaling sympathy sickness. Embodiments include a system having a communication among the members, each member having a cross-system coupling facility (XCF), and a method of managing sympathy sickness, the method including detecting a sympathy sickness condition affecting at least one of the members, documenting the sympathy sickness condition and implementing a policy rule to resolve the sympathy sickness condition.
