    摘要: The automatic exposure control devices of contemporary X-ray generators have a constant lead time which accurately takes into account the actual ratios or delays only for a given setting of current and voltage. Particularly in the case of high voltages and small currents, the lead times are too short, thus giving rise to overexposures. The invention provides an automatic exposure control device in which the lead time is calculated from the exposure data by an arithmetic unit. The lead time is adjusted on a correspondingly constructed adjustable lead time network. An arithmetic unit of this kind is not required for the programmed exposure technique. The correct lead times can then be programmed and stored together with the other exposure parameters.

    摘要: A method for checking the refresh function of a memory having a refresh device includes the steps of, first, ascertaining whether or not refresh request pulses are being produced on the information memory and, if so, at what intervals of time from one another these refresh request pulses are produced. Next, a control unit for the information memory is supplied with refresh test pulses produced outside of the information memory instead of being supplied with the refresh request pulses. Then, the refresh test pulses are used to check a refresh device situated on the information memory.
