Generator for generating electrical ignition or detonation energy in a spin projectile through a piezo element utilizing the spin of the projectile for generating the electrical energy. The piezo element lies against the interior of the projectile shell and is polarized radially relative to the longitudinal axis of the projectile. Preferably, the piezo element is of tubular configuration. A core is radially movably supported interiorly of the projectile shell so as to charge the piezo element during the rotational acceleration of the projectile.

A generator for generating electrical ignition energy through a piezo element in a spin projectile. A guide band on the projectile deforms upon entry into the riflings of a weapon barrel. To generate the ignition energy due to the deformation of the guide band, the piezo element is a tubular member polarized radially relative to the longitudinal axis of the projectile. The outer circumference of the piezo element lies against the projectile shell. The piezo element is stiffened along its inner circumference by a stiffener ring positioned thereagainst.

An apparatus for monitoring a trench profile of a substrate includes a radiation-emitting unit for irradiating the substrate with infrared radiation. The intensity and/or polarization state of the infrared radiation reflected from the substrate is measured at a multitude of measuring frequencies. An analyzing unit determines the respective reflectance and relative phase change and/or relative amplitude change in relation to the respective measuring frequency. In addition, a reflectance spectrum, a relative phase change spectrum and/or a relative amplitude change spectrum may be obtained. By performing a Fourier transformation of the respective spectrum, a secondary Fourier spectrum is obtained. The secondary Fourier spectrum plots a virtual amplitude against corresponding values of a frequency periodicity that correspond to a substrate depth. Peaks of the virtual amplitude may indicate reflective planes within the substrate at respective depths. Thus, rough sections in the trench profile may be identified without modeling.
摘要:
A detonator for the electrical ignition or detonation of detonating materials, such as explosives. The detonator incorporates at least one piezo element which is at least partially encompassed by a secondary explosive. The piezo element is subjected to a steeply rising voltage impulse and thereby rapidly expanded so as to generate a shock wave which will detonate the secondary explosive.

An apparatus includes an evaluating unit and a peak detection unit. The peak detection unit may be configured to determine at least one peak parameter of a peak in a Fourier transformed reflection spectrum of infrared radiation reflected off a sample that may comprise trench structures. The evaluation unit may be configured to determine from the at least one peak parameter and from a correction value containing information about an effective refractive index of the sample, a trench parameter of the trench structures.

摘要:
A method and a circuit arrangement are provided for the transmission of communication signals over switching centers of a first switching network and of a second switching network operating with different transmission procedures. The transmission is executed with the assistance of a decentralized converter in which a fixed assignment between the transmission lines of the first switching network and the virtual channels to be employed on transmission lines of the second switching center for a signal transmission is defined. Of the signals to be transmitted, only the signal portions effecting the execution of network-dependent procedure divisions are converted in the converter. The data signals appearing in accordance with the network-independent procedure divisions are combined in unaltered form with the converted signal portions.
