Inventor: PHAM BINH
IPC: G06F13/16
Filed: 1999-12-07
Abstract: An apparatus, system, and method for speeding up data transfers while reducing bus contention during repeated consecutive read-write operations. By reducing the length of time during which selected data pulses are driven on the memory bus, a higher percentage of usage of the memory bus may be attained without increasing the likelihood of bus contention and resulting degradation or damage to the memory system.  The selected data pulse is preferably the write data pulse driven on the memory bus by the memory controller. A zero bus turnaround protocol may be implemented. The memory controller may include interface circuitry and write control circuitry that outputs an associated control signal to a three-state buffer. The three-state buffer, after being enabled by the associated control signal, drives write data on a data line of a memory bus. The turn-on delay associated with the three-state buffer exceeds the turn-off delay also associated with the three-state buffer. Thus, the three-state buffer drives data pulses on the data line for a shorter period of time than the period of time that the associated control signal is provided by the write control circuitry to enable the three-state buffer. The write control circuitry may output a shortened associated control signal. The associated control signal may be asserted for a shorter period than the memory controller clock period or the duration of a memory read data pulse. The write control circuitry may implement a turn-on delay or a shortened control signal which ends prior to the end of the memory controller clock pulse.

Title: Method of manufacturing methanol
Inventor: SEIKI YOSHIO
IPC: C07C31/04
Filed: 1999-12-06
Abstract: A raw material gas containing hydrocarbon as a main component is supplied together with steam to a reformer through a moistening device to form a synthetic gas containing hydrogen, carbon monoxide and carbon dioxide as main components by the reaction between the hydrocarbon contained in the raw material gas and the steam. In forming the synthetic gas, carbon dioxide is supplied to at least one fluid passageway selected from the group consisting of the fluid passageway positioned upstream of the moistening device and the fluid passageway interposed between the moistening device and the reformer. As a result, the excess hydrogen contained in the gas formed in the reformer is effectively utilized without bringing about deactivation of the methanol synthesizing catalyst in the methanol synthesizing step. Also, carbon dioxide is effectively utilized to decrease the amount of carbon dioxide discharged to the outside of the system.      Further, it is possible to decrease the amount of steam supplied to the reformer.

Title: Open loop current control ballast for low pressure mercury germicidal uv lamps
Inventor: DE VRIES PIETER
IPC: H05B41/14
Filed: 2000-01-26
Abstract: An apparatus for starting and operating UV lamps, comprises an AC line powered circuit and a UV lamp. The circuit has a variable frequency AC source, providing AC current to the UV lamp and a ballasting inductor, connected in series with the UV lamp. The inductor and the lamp form a nonresonant coupling sub-circuit where a flow of current from the AC source through the UV lamp is limited by the ballasting inductor. The circuit does not develop dangerously high output voltages if the UV lamp is disconnected or burnt out, as would be the case with resonant output circuits, unless additional circuit protection was implemented. The impedance of the ballast inductor varies with the current frequency, enabling it to act as a current control element with changes in the output frequency. An open loop control circuit of the present invention maintains the lamp current at a relatively constant level without the complexity imposed by closed loop current control methods.
