Patent EP-0031117-A3 (EP)
IPC: H02P27/04
Filed: 1980-12-15
Abstract: Zur Steuerung des Drehmoments und/oder der Drehzahl 
einer Asynchronmaschine, welche über einen Umrichter mit 
Gleichstromzwischenkreis gespeist wird, wird vorgeschla­
gen, die Läuferfrequenz f₂ in Abhängigkeit von der Läufer­
drehzahl f n , jedoch unabhängig vom Lastzustand der­
Maschine vorzugeben und die so vorgegebene Läuferfre­
quenz f₂ durch einen überlagerten Regelkreis für die Wechsel­
richterausgangsspannung derart zu korrigieren, daß bei einer 
Erwärmung der Maschine die Wechselrichterausgangsspan­
nung konstant bleibt. Die Regelzeitkonstante des Ausgangs­
spannungsregelkreises ist größer als die Haptfeldzeitkon­
stante der Maschine.  
     Durch diese Vorgabe der Läuferfrequenz läßt sich bei 
jeder Läuferdrehzahl eine Maschinenspannung einstellen, bei 
der die Verluste im Wechselrichter und in der Maschine 
minimal werden. Durch die erwärmungsbedingte Korrektur 
der Läuferfrequenz f₂ bleibt das Verhältnis R₂/s nahezu kon­
stant, so daß die Größe des von der Maschine abgegebenen 
Drehmoments bei gleichem Maschinenstrom und gleicher 
Maschinenspannung praktisch nicht beeinflußt wird.

Title: Low-voltage protective circuit breaker with blocking lever
IPC: H01H71/62
Filed: 1981-08-06
Abstract: In the low-voltage circuit breaker that has a toggle lever system connecting the actuating arm to a carrier that moves the movable contact, a locking lever is provided to prevent transfer of the operating lever handle to its "off" position if the movable contact is welded to the stationary contact. The locking lever is pivoted about a bearing support formed in the housing of the circuit breaker. The opposite end of the locking lever is connected to the handle to be pivoted by it. The locking lever has an angled-off projection that extends into the path of movement of the carrier and is positioned to engage the carrier if the latter is unable to move from its "on" position due to welding of the contacts together. When the contacts are not welded together, the locking lever enforces the toggle levers to snap through to their "off" position before the angled-off part of the locking lever comes into contact with the carrier of the movable contact.

Patent EP-0151880-A3 (EP)
Title: Radiation measuring apparatus and method
IPC: G01T1/18
Filed: 1984-12-18
Abstract: An apparatus and method for measuring radiation field strength uses a pulse enabled G-M detector tube (13 or 14) and is based on the equation R=K/t, where r is the radiation field strength, t is the time till first strike, and K is a proportionality constant for the given apparatus. The G-M tube (13 or 14) is enabled by pulsing the bias voltage across the tube up into its active region and then measuring the elapsed time interval to the incident of first strike. Since the reciprocal of this time is proportional to the radiation field strength, all information necessary to determine the field strength has been obtained. A constant wait time is employed after each strike to ensure that the G-M tube full recovery time has expired, and the G-M tube is then enabled and the process repeated. Because of the random nature of radiation phenomena the confidence level that any given measurement is an accurate representation of the true average field strength is low. Many measurements are taken and averaged for high confidence factors. For low fields, the lost time due to the deliberate "wait after strike" is a small percentage of the total time, so is of little consequence. In high fields, the "time to strike" is short, so many measurements can be made, again rendering the lost time of little significance.

diffusion region (10a) is formed in the periphery of the 
Schottky barrier diode and between a metal layer (13) 
connected to a word line and the N⁺-type buried layer (2). By 
the capacitor, the stability of the memory holding state is 
improved without deteriorating the operating speed of the
