Title: The minimisation of surface originating contamination in electron microscopes
IPC: H01J37/20
Filed: 1979-12-20
Abstract: Surface originating contamination of a sample (18) in an electron microscope is minimised by indirectly irradiating the sample with low energy electrons supplied by electron gun (10) adjacent sample holder (20). The gun supplies electrons with energies between 50 eV and 500 eV, a beam current in the microamp range and a divergent beam with an angle of between 2 DEG  and 15 DEG . The sample may be irradiated either before and/or during imaging of the sample. Neutralization of positive charge induced on the sample by secondary electron emission and subsequent non-attraction of hydrocarbons to the sample is considered. Also excess negative charge on the sample causes hydrocarbons to desorb more rapidly. <IMAGE>

Filed: 1980-04-16
Abstract: Abutting side walls 17,18 of adjacent circuit-breaker units have recesses 19 accommodating a carrier plate 22 of a coupling element 21 mounted pivotally on a projection 26. Plate 22 has two projections 23,24 on each side extending through apertures 20 in the side walls 17, 18 into the two units. One set of projections 23 on each side are adjacent studs 8 each on a pivotable holder 7 for a pawl 9 of the latch, said pawl being engaged by release lever 1 in the make position. The other projections 24 on the two sides are each situated below a projecting edge 25 of the release lever 1.

The stud 8 on the pawl holder 7 strikes against the associated projection 23 and rotates the coupling element 21. Consequently the other projection 24 lifts the release lever 1 of the adjacent circuit breaker unit which is also tripped. <IMAGE>

Title: High efficiency light weight audio amplifier and power supply
IPC: H03F3/68
Filed: 1979-11-06
Abstract: Amplifier circuit (2, 102, 1100, 1500, 1600) and transformer based power supply (24, 104, 500, 700, 1710) wherein greater efficiency is achieved by using the input signal characteristics to control various aspects of the circuit operation. The transformer primary winding (8, 104a, 500a, 700a, 1710a) is energized by a pulsed power supply (6, 126, 502, 702, 1702) which is duty cycle modulated in response to the signal being amplified. One embodiment of the amplifier employs output transistors (Q1101, Q1103, Q1105, Q1107, Q1109, Q1111) connected to respective stepped voltage levels. Amplifier control circuitry (1126, 1130, 1138, 1140) acts in relation to the input signal amplitude to more evenly distribute the voltage drop across the interconnected transistors (Q1101, Q1103, Q1105, Q1107, Q1109, Q1111), thus reducing amplifier power requirements and minimizing distortion in the amplifier output. In another embodiment, a stereo amplifier constructed in accordance with the present invention contains a network (1602) for inverting the audio signals received by a first amplifier input channel (1600). The inverted signals are thereafter processed in out-of-phase relationship to the signals in the second amplifier input channel (1500) to more efficiently utilize the power supply. In yet another embodiment, the power supply (1710) itself is constructed with a number of fault detecting circuits which sense fault conditions in either the power supply or the amplifier and shut the power off accordingly.
