Title: Arcless switch
Inventor: KIM IN-SOK
IPC: H01H35/10
Filed: 1985-06-21
Granted: 1988-07-12
Abstract: In a circuit breaker having a triac between the power side and the load side, the contact gap of the power side (A) is narrower than the gap of the load side (B).  When a switch (SW) is turned on, the contact of the power side is closed first to allow the surge current through a triac, then the contact of the load side is closed later to allow the current through A,C,B.  When the switch is turned off, the contact of the load side is opened first to allow the current through the gate of the triac, then the contact of the power side is opened later.  So the surge current generated when switching on and off is absorbed into the triac and thus arc generation can be prevented.

Title: X-ray protecting stabilization circuit
Inventor: RYU YOUNG-KWAN

Abstract: The circuit includes an X-ray release inhibiting circuit (50) in addition to the usual components of the  conventional  circuit. If a high voltage which is sufficient to  release  X-rays  by  the output of an X-ray release control circuit (40) is  detected,  the X-ray release inhibiting circuit (50) controls  a  pulse  duration switch (13) of a horizontal deflecting signal output section (20). Thus if a high voltage is produced, the variation of the  duration of trigger pulses is  inhibited,  thereby  stabilizing  the  X-ray output.

Granted: 1996-05-15
Abstract: The present invention discloses an Fluorescence X-ray spectrometry method and device for determining the type and quantity of metals elements in metal and metal alloy samples, particularly precious metal and precious metal alloy samples. The invention provides a method and an apparatus in which an object to be analyzed is positioned so that an X-ray beam that will be generated will coincide with a measurement point on the surface of the object where it is desired that the analysis be carried out. The measurement point is exposed to an X-ray beam having a diameter of 0.1 to 5 mm, causing fluorescence X-ray radiation to be generated which is sampled. Spectral analysis of the captured fluorescence X-ray radiation is then carried out wherein the intensity of selected peaks corresponding to target elements is determined, whereby the relative composition of selected elements can be calculated, thus providing selective quantitative analysis for target elements at the measurement point. The relative composition can be calculated by performing a computer analysis of the spectrum of the captured fluorescence X-ray radiation in which a fundamental parametric method is applied to the intensity values for peaks corresponding to each target element.

Abstract: A card counter (10) prints card inventory information locally and communicates with a remote computer (43) for permanent storage and retrieval of inventory information. A microprocessor controller detects a counting error in response to the actual count failing to match a preset count, failing to match a precount information machine read from a machine readable precount label (130) attached to the cards (18), in the event of a phase error from a pair of parallel scanning card sensor circuits (58, 59) or if the final counts of the two card sensor circuits (58, 59) do not match. In the event of detection of a counting error, an error indication is provided and entry of the count into an accumulator memory is inhibited. The preset number is entered into memory by selectively entering an actual count into the preset memory. A pair of separate accumulators are provided for concurrently accumulating totals of two different groups of cards (18). The card sensor circuits (58, 59) are digitally filtered by the microprocessor (44) which also automatically performs self diagnostics to reduce countin errors due to malfunction. Malfunction of a scan drive motor (61) is reduced through provision of a slip clutch (Figs. 10A and 10B).
