Abstract: A perforated screening component (50) that surrounds the lamp (4) serving as light source is installed in galvanic contact with a metallic housing (2) having a cap wall (30) penetrated by a lamp cap (3). The screening component (50) consists of a sleeve-shaped metal cage (51) open on both sides and a metal flange (52) on the cap side. The latter (52) is combined with the cap wall (30) of the housing, which retains the cap (3), to form a double-walled component. The screw axis (13) of the lamp (4) extends essentially parallel to the plane of the coupling flange (7) of the housing. The double-walled nature of the metallic boundary of the housing on the cap side effects a microwave-proof sealing of the oven lamp in conjunction with an extremely shallow depth of installation and a low overall volume. <IMAGE>

Abstract: A random number generator includes a noise signal generating device for supplying a noise signal, a sampling device connected between an output of the noise signal generating device and an output of the random number generator and sampling the noise signal in a sampling state and not sampling the noise signal in an idle state. The random number generator further includes a control oscillator for supplying a control alternating signal, the frequency of the control alternating signal of the control oscillator not being rigidly coupled to the frequency of the noise signal. The random number generator further includes an enabling device which puts the sampling device in the sampling state when the noise signal or the signal derived from the noise signal is in a first trigger state, and when, subsequently, the control alternating signal of the control oscillator is in a second trigger state. This is to ensure that the frequency of the output samples of the random number generator depends on the frequency of the noise signal, whereas the phase position is determined by the frequency of the control oscillator. Thus, the frequency of the output samples can be set and adjusted to existing requirements in a simple manner using the frequency setting functionality of the noise signal generating device.
