Abstract: A charged particle beam deflector has a simple structure for providing a uniform potential distribution over each blanking aperture. The deflector is easy to operate, and stabilizes the shape of a charged particle beam component passing through each blanking aperture even with a low deflection voltage. A pair of deflecting electrodes (10,11) are arranged on opposing inner walls of each blanking aperture (1). A voltage applied to the deflecting electrodes is controlled to correctly deflect the charged particle beam component passing through the blanking aperture. A pair of resistance films (12,13) are arranged on the other opposing inner walls of the blanking aperture, to connect both sides of the deflecting electrodes. 
     The deflector may employ patterned beam generating apertures. A pair of deflecting electrodes are formed on opposing inner walls of each of the apertures. A voltage applied to the deflecting electrodes is controlled to correctly deflect a charged particle beam component passing through the aperture.

Abstract: A FET comprising two or more gate pads or terminals, and a reflexion type-oscillator including the above-mentioned FET. In this oscillator, a dielectric resonator is connected through a coupling line to the first gate pad of the FET and an output terminal is connected to the second pad. When the drain pad of FET is connected to ground, and a suitable value of capacitive reactance is added to the source pad, then a negative resistance -R appears on the first gate pad, and thus oscillation occurs at a resonance frequency fo of the dielectric resonator. If the load resistance value viewed from the second gate pad is set to R, the maximum oscillation output occurs. Accordingly this oscillator enables to set the oscillation conditions between the source and gate pads of the FET, and the output matching conditions between the second gate pad and the output terminal separately, and thus allows to set the oscillation conditions and the output matching conditions, respectively, simultaneously to the best.

Abstract: The joint prosthesis comprises a first prosthetic part (11), an intermediate part (13), a coupling member (15) and a second prosthetic part (17). The first prosthetic part comprises means for anchorage in the bone, e.g. in the femur, and two condyles (19). These condyles (19) articulate with the bearing surfaces (21) of the intermediate part (13). The second prosthetic part (17) possesses a sliding surface (24) and means (25, 27) for anchorage in the bone, e.g., in the tibia. A bore (31) receives a pivot (33) of the coupling member (15). The coupling member (15) possesses a guide part (16) which cooperates with the guide track (35). The movement sequence of the joint prosthesis corresponds largely to the physiological movement sequence of the natural joint. The condyles (19) and the bearing surfaces (21) are used for the articulation movement. The translation movement, e.g. from anterior to posterior, is brought about by the displacement of the intermediate part (13) on the sliding surface (24) due to the coupling member. The pivot (33) permits rotation about the axis (39). <IMAGE>

Abstract: The patent describes a fault-current protection switch having a summation current transformer whose secondary winding is connected to an energy storage circuit which is independent of the mains voltage. A monostable or bistable relay (converter relay) is operated in a pulsed manner by this energy storage circuit when a fault current to earth flows in the protected installation. When the relay contact is closed, the excitation current taken from the mains operates an electromagnetic trip device (latching trip device) which trips the latching mechanism of the fault-current switch. Thereafter, in the case of the bistable relay, the bistable converter relay is reset to its original position again either mechanically by a suitable coupling to the latching mechanism or electrically by a time delay circuit, as a result of which the relay contact is opened and the fault-current switch is ready for switching on again. In the case of the monostable converter relay, the relay automatically returns to its original position, the energy storage circuit being matched to the winding of the relay such that the duration of the pulse which the energy storage circuit supplies is long enough for the excitation current from the mains to operate the latching trip device. <IMAGE>
