Title: Examining integrated circuits on semiconducting plates - determining weak points by inducing errors with selective alpha particle irradiation
Inventor: URL KARLHEINZ DR RER NAT
IPC: G01R31/302
Filed: 1980-10-29
Abstract: A method of examining an integrated circuit on a semiconducting plate enables otherwise only sporadically occurring faults to be induced, thus enabling measures to be taken to eliminate weak points within the integrated circuit. This is achieved by irradiating selected areas of the circuit with alpha radiation whilst the remaining parts of the circuit are working under normal operating conditions. The failure characteristics so induced are observed. The method involves the masking of selected circuit nodes which are considered to be error sources. A method esp. for use with unipolar write-read memories involves establishing the number of errors of a first and second type occurring for logical base conditions of a first and second type and comparing the numbers of errors of each type.

Title: Stamp for a tablet-compressing machine
Inventor: MENSE BRUNFRID
IPC: B30B15/06
Filed: 1981-04-18
Abstract: A known stamp for a tablet-compressing machine is provided at its end with a driving head, which is undercut to form a mushroom shape and with a holding shaft, which is connected to the said driving head, has the shape of a regular cylinder and to which there is connected, by means of a conically tapering transition section, a stamp shaft, at the free end of which there is situated an embossing head which is offset in a shoulder-like manner. The end part of the stamp shaft is replaced by a hard metal attachment which has been soldered on so as to be flush with the said shaft. In the case of the known tablet-pressing machine, there is in particular a danger that the soldered joint between the hard metal attachment and the rest of the stamp shaft will be plastically deformed, which could result in changes in length or be associated with an impermissible modification of tablet volume. The invention has eliminated the above disadvantage by making the hard metal attachment include the conical transition section as well as the stamp shaft, to which section there is integrally connected a rotationally symmetrical insertion pin, which tapers towards the driving head and is made of the same material as the transition section. The outer casing surface of the insertion pin bounds the soldering surface, while an inner casing surface which extends parallel to the soldering surface and belongs to a reception space provided in the holding shaft shaped like a regular cylinder forms the counter-surface.

Patent DE-3124357-A1 (DE)
Title: Laser interferometer
Inventor: SCHUESSLER HANS-H DR DIPL ING
IPC: G01B9/02
Filed: 1981-06-20
Abstract: The invention relates to a laser interferometer having an interferometer splitter (5), which is held in a constant position relative to the specimen (1) and has a reference reflector (7), a probe (8) which can be moved both parallel and transverse to the principal measuring axis (19), and a measuring reflector (12) which is held in a constant position relative to the probe (8). In order to shorten and simplify the design of the interferometer, the measuring reflector (12), which is constructed as a flat mirror, is mounted on the probe (8), the latter being moved in a straight line out of the principal measuring axis (19). The diameter of the measuring reflector (12) is sufficiently large for the beam path not to be interrupted in this relative transverse movement (h). In order to eliminate slight alignment and tilting errors in the measuring reflector (12), the measuring beam is cast onto the measuring reflector (12) twice exactly parallel to itself by virtue of an intermediate reflection (7, 16, 27), the measuring beam finally reflected always coming to be situated exactly parallel to the direction of incidence. The result is high-contrast bright/dark transitions during the formation of interference and, moreover, high resolution. Two measuring beam arrangements (17, 18) emanating from one laser light source can be provided symmetrically with respect to the principal measuring axis (19) in order to observe Abbe's principle. These measuring beams are likewise insensitive to tilting and alignment errors: moreover, a four-fold passage of the measuring beam through the measurement path produces a four-fold resolution. <IMAGE>

Title: Method and arrangement for monitoring the flow of missile (fission) material and determining the burnup of nuclear elements by measuring neutron coincidence
Inventor: QUANDT ULRICH DIPL PHYS DR
IPC: G21C17/06
Filed: 1981-07-01
Abstract: The present invention simplifies previously customary methods for measuring coincident fission neutrons, with the result that conventional and standardised meters can be used with great accuracy. It is proposed for this purpose to use a time/amplitude converter (4) which is fed with the signals from two neutron detectors (10, 20) arranged around a source (1). The output signals of the time/amplitude converter (4) are analysed by a multichannel analyser (5) and visualised, for example on a viewing screen. Coincident fission neutrons cause a peak in the resulting spectrum whose net area is a measure of the quantity of fissionable material in the source. <IMAGE>
