IPC: B23K26/08

Abstract: The present invention provides a laser engraver for engraving a pattern on a workpiece. The pattern is established on the workpiece by using a X-Y assembly(32a,32b) to move a laser beam in two dimensions relative to the workpiece. The X-Y assembly employs a X proportional-­integral-differential (PID) controller (34a) and a PID (34b) to generate control signals for moving the X-Y assembly. The PIDs generate the control signal based upon the current position of the laser beam and a target position for the laser beam. The current position is provided by encoders (36a,36b) operatively attached to motors (38a,38b) that, in turn, move mirrors (44a,44b) that direct the laser beam to the workpiece. The depth of cut is, preferably, controlled by using the integral of the difference between the position of the laser beam as it is moved by the X-Y assembly and a reference position. Alternatively, proportional control based upon the absolute difference between the position of the laser as it is moved by the X-Y assembly and the reference position can be utilized.

Abstract: A device (40) for measuring energy in fuel gas comprises a solid electrolyte oxygen pump (10) for generating an amount of oxygen in response to current being supplied to the pump (10). A sample of the gas is mixed with the oxygen from the pump (10) to produce a mixture which is subjected to complete combustion in a catalytic combuster (12). An oxygen sensor (14) is connected to the catalytic combuster (12) for measuring excess oxygen in the exhaust gas from the combuster (12). A signal from the oxygen sensor (14) is compared in a feedback control unit (22) to a known and desired amount of excess oxygen in the exhaust gas. If there is too much or too little oxygen in the exhaust gas, a feedback signals used to adjust the value of current being supplied to the oxygen pump (10) until the actual amount of excess oxygen is equal to the selected amount of excess oxygen. The selected amount of excess oxygen is indicative of complete combustion of the sample mixture. With the excess oxygen equalling the desired oxygen in the exhaust gas, the value of current being supplied to the pump (10) is used to calculate the energy in the fuel sample.

Abstract: In accordance with the disclosed method (300), a surfactant (107) is mixed with a sample (105) prior to injection (303) onto a separation column so that both polar and nonpolar sample components can be enriched at the column head. The components are then separated (304) by reverse-phase gradient elution. The surfactant (107) permits nonpolar analytes to be dissolved in a solvent ( e.g ., water) which is sufficiently polar such that polar analytes are concentrated along with nonpolar analytes at the head (204) of the column. Thus, on-column enrichment is provided. The effects of the surfactant diminish during elution so that substantial separation of analytes is still obtained. As a result of the on-column enrichment, smaller-bore columns can be used. The smaller-bore columns provide for more concentrated peaks and thus greater detection sensitivity and quantitation accuracy.

Abstract: The deviation ( DELTA U, DELTA I) between measured quantity (Um, Im) and a compensation quantity (Uk, Ik) tracking the latter, is supplied to a comparator (K) which forms a binary control signal (KA) when this deviation is present. A microprocessor (CU) changes and, in particular, increases or decreases a coded control value (SW) depending on the presence or absence of the binary control signal (KA). Finally, a digital/analog converter (DAU) corrects the compensation quantity (Uk,Ik) in accordance with the coded control value (SW). A controller (R) is advantageously arranged between the comparison point (V) of measured and compensation quantity and the comparator input (KE). The zero offset and gain error of the device can be determined with the aid of a further switching means assembly. The microprocessor advantageously drives the switching means assembly during calibration routines and corrects the coded control value (MSW) for the purpose of measured-value output. <IMAGE>

This small oxygen electrode comprises a flat electrode substrate having at least two electrodes (a working electrode and a counter electrode) formed thereon, and a container substrate having dents formed to confront the two electrodes and contain an electrolyte therein, which is bonded to said flat electrode substrate, wherein of said dents, the dent confronting the electrode constituting the working electrode has a through hole extending to the side opposite to the flat electrode substrate and a gas-permeable film is formed to cover said through hole. By dent of this structure, the preparation of an oxygen electrode can be conducted while maintaining a wafer form throughout the process, and formation of an electrode pattern can be facilitated. The method of bonding the fluorine resin film comprises treating the fluorine resin film with an agent containing metallic sodium, then treating the fluorine resin film with a silane coupling agent, fusion-bonding the treated fluorine resin film by heating, and if necessary, conducting subsequent treatments in vacuo. By adopting this method, the fluorine resin film can be bonded tightly to the substrate and peeling of the fluorine resin film from the substrate can be prevented.

Abstract: The circuit (11) provides faster settling to a new frequency in a phase-locked loop frequency synthesizer (10) that uses a programmable divider (16) and a phase detector (17). The circuit (11) is adapted to stop the divider (16) while its program is being changed, and then restart the divider (16) on command. The startup time of the divider (16) is automatically adjusted such that the divider output is in phase with a reference input to a phase detector (17). The outputs of the phase detector (17) are also blanked during the time period that the divider (16) is stopped. The circuit (11) reduces the time required for the phase locked-loop frequency synthesizer (10) to settle to its new frequency and phase when the frequency is changed. The timing of the divider startup eliminates the large phase transient that may occur when the divider startup timing is random, thus shortening the time that must be allowed for the synthesizer output to settle to its final phase. This circuit (11) is of particular value in a fast settling synthesizer design in which a VCO is pretuned to a close approximation to the new output frequency and then the loop is closed to drive the frequency to its exact value. The circuit (11) is well adapted for use in spread spectrum and frequency-agile radar systems, or spread spectrum communications systems.
