A spark plug is disclosed and comprises: a metal tube which interiorly defines an axis and is externally-threaded for engine block engagement; an insulator having a portion which is disposed inside the tube and extends therebeyond; a positive electrode extending through the insulator and projecting beyond the extending portion of the insulator; and an annular ground electrode coupled to the tube. The electrodes are configured such that a spark gap defined therebetween comprises an elongate channel which opens axially and away from said insulator and is substantially unobstructed in the axial direction. The ground defines a void having: a central portion occupied by the positive electrode in use; an annular channel surrounding the central portion; and a plurality of lobes, each being positioned with respect to the central portion in a manner analogous to the placement of the planet gears with respect to the sun gear in a planetary gear
摘要:
A system, method and computer program product for steering a time-of-day (TOD) clock for a computer system having a physical clock providing a time base for executing operations that is stepped to a common oscillator. The method includes computing a TOD-clock offset value (d) to be added to a physical-clock value (Tr) value to obtain a logical TOD-clock value (Tb), where the logical TOD-clock value is adjustable without adjusting a stepping rate of the oscillator.

A communication port of a communications interface of an information handling system comprises a plurality of virtual ports. A first command is issued to obtain information indicating a number of images of virtual ports supportable by the communications interface. A second command is then issued requesting the communications interface to virtualize the communication port. In response to the second command, one or more virtual switches are then configured to connect to the communication port, each virtual switch including a plurality of virtual ports, such that the one or more virtual switches are configured in a manner sufficient to support the number of images of virtual ports indicated by the obtained information. Thereafter, upon request via issuance of a third command, a logical link is established between one of the virtual ports of one of the virtual switches and a communicating element of the information handling system.

A method of performing memory mapped input output operations to an alternate address space comprising: establishing a first instruction directed to a first memory mapped input output alternate address space associated with an adapter to store data in accordance with a definition of a z/Architecture; establishing a second instruction directed to the first memory mapped input output alternate address space associated with an adapter to load data in accordance with the definition(s) of the z/Architecture; and wherein a process issues at least one of the first instruction and the second instruction and thereby causes execution of at least one of the store and load with the first alternate address space.

Provided herein are water-soluble, functionalized fullerenes, and processes for producing water-soluble, functionalized fullerenes. The process includes sulfonating a fullerene in an acidic solution comprising sulfuric acid to produce a sulfonated fullerene, isolating the sulfonated fullerene from the acidic solution without neutralizing the acidic solution, reacting the sulfonated fullerene with hydrogen peroxide to form a reaction product, and isolating a polyhydroxylated fullerene from the reaction product produced from reacting the sulfonated fullerene with the hydrogen peroxide. The process of producing water-soluble fullerenes further includes functionalizing a polyhydroxylated fullerene with one or more pendant functional groups by reacting the polyhydroxylated fullerene with one or more functional group precursors.
摘要:
An adapter, used with a spark plug body and an engine block, is disclosed. The body defines an axis and has adjacent one end, a coaxial metal ring. A coaxial metal tube extends from the ring towards the other body end and is threaded in said block in use. An insulator, having a portion inside the tube, extends axially, from inside the tube, beyond the ring, and has a void therethrough. A positive electrode occupies the void and extends axially beyond the insulator to a terminus. In use, the adapter is secured to said body and comprises: a positive electrode extender in electrically-conducting relation to the positive electrode and a ground electrode extender in electrically-conducting contacting relation to the ring. The adapter is configured such that a gap defined between the positive and ground extenders comprises a channel which opens axially away from said body and is substantially unobstructed axially.
