摘要:
A write precompensation circuit includes a plurality of current-controlled delay buffers connected to form a delay line having selectable output taps. The precise delay of each delay buffer is controllable by a secondary control current derived from a master control current such that the precise delay is a precise percent of an oscillator period. The master control current is also used to control the period of a master write clock generated by a current-controlled ring oscillator of delay buffers. A write precompensation method includes steps of controlling current in delay buffers in a current-controlled ring oscillator used to generate a master write clock and current in delay buffers in a current-controlled delay line to maintain delays through delay buffers of the oscillator and the delay line in predetermined proportions to each other.

When a service is provided in a service stream between end devices controlling the service stream by using first protocol, there is also a need to control the service stream in the network via which the service stream is or is to be transmitted. The service stream is controlled in the network by utilizing first protocol messages which are separated (204) from other traffic transmitted in the network.

A process for the continuous preparation of silicon-base complex ferrous alloys from cheap raw materials by preparing a charge with a high electric resistance and reducing the same in an electric arc furnace. A charge is assembled which contains the total amount of carbon in a 0.82 to 0.99-fold quantity of that required to reduce all oxides of the charge to elements and achieving this carbon content by preparing pellets which, in addition to the binding material, contain(a) as oxide to be reduced in an amount of at least 50% by weight such oxides of only base-forming or only amphoteric or only acid-forming elements which form with each other compounds or eutectics melting above 1600.degree. C., and(b) a carbonaceous reducing agent and/or carbides in such an amount that the quantity of carbon is either 1.05 to 1.35 times higher than required to transform the oxides of the pellet to the carbides or 0.66 to 0.02-fold of the quantity required to reduce the oxides of the pellet to metallic elements, and assembling the charge(.alpha.) from pellets containing an excess of carbon and/or from lumpy carbides and(.beta.) from carbon-deficient pellets or from a lumpy oxide of a base-forming or amphoteric or acid-forming element and(.gamma.) from lumpy carbon carriers, and optionally(.delta.) from an iron additive, in the absence of boron trioxide.

A process for the production of short cooking time rice is characterized by that hulled rice of at least 10% moisture content, if required in packaging suitable for ready cooking, is heat treated for 1 to 30 minutes continuously or interrupted by equal or alternating capacity microwave radiation, to reach maximum 130° C. An apparatus for the production of short cooking time rice has a microwave furnace with a tunnel made from a suitable material, wherein the rice packed into packages is movable within the tunnel by a conveyor. Regarding the easy and short process, a remarkable energy saving is possible.

A composite load circuit for use within another circuit includes at least one amplifying transistor. The composite load circuit includes first and second transistors connected in parallel. Each load transistor has a gate that receives a common control voltage. Each load transistor also has a different turn-on threshold voltage. A resistor, connected in parallel with the load transistors, limits an effective impedance of the load transistors.

Disclosed herein is a junction box having a housing and a plurality of straps. The housing includes a plurality of ribs with posts extending therefrom. Each one of the straps has a plurality of receiving areas defined by a contiguous radial surface, such as a countersink surface. The posts extend through the receiving areas and securingly retain the straps against the housing. In an exemplary embodiment of the present invention, the posts are substantially frustoconical prior to assembly and may be characterized as deformed frustrums after assembly.
