Patent JP-H0423090-A (JP)
Title: Card device
Inventor: HAYASHI NAOKI
IPC: G06K13/06
Filed: 1990-05-17
Abstract: PURPOSE:To improve the reliability by allowing a card having a true/false discriminating part to pass a true/false discriminating means. CONSTITUTION:When a card 10 is inserted to reach a front end detecting sensor 23, a pulse of a magnetic bar code 11 in the true/false discriminating part is detected by a magnetic head 26. A preliminarily cleared pulse counted value is counted up by one, and the card 10 is recognized as a regular card when the counted value reaches 5. If pulses are not detected by the head 26 within two seconds set to a timer or the number of bar codes is not 5, the card 10 is processed as an illicit card. Since carrying of the card is started after true/ false discrimination of the card, the damage of a device due to leading-in of an illicit card is prevented and the reliability is improved.

IPC: G01N23/225
Filed: 1995-05-29
Abstract: PURPOSE: To enable the depth-directional compositions of plural elements with different concentrations to be analyzed easily in a short time by setting measuring requirements for windows for the plural elements so that the signal strength of each of the elements has appropriate magnitude, and measuring their spectra. CONSTITUTION: The surface layer of a sample 10 is sputtered with an ion beam from an ion gun 12, and an electron ray is applied to that part from an electron gun 11 to produce Auger electrons, which are then subjected to energy spectral diffraction 13 to obtain signal strength. Next, windows are set to a range consisting only of a narrow energy range containing the Auger electron peak which is desired to be measured, and the detection sensitivies of an analyzer 13 for the individual windows are separately set by an analyzer controller 21 for the measurement of signal strength. As ion sputtering and spectrum measurement are alternately repeated under control of a CPU18, the compositions in the dopth direction of plural elements which greatly differ in concentration can be analyzed in a single operation, resulting in reduced measuring time.
