Abstract: An electric connector includes two complementary connector members, one of which has spring contacts as contact elements and the other has blade contacts as contact elements, wherein the contact elements are mounted in a row or in several parallel rows on base members. The base members are mounted on frame-like enclosing members of housings which extend parallel to the direction of insertion of the contact elements and which serve for the mutual guidance of the housings during the insertion. In the joined state of the connector members, the spring contacts and the corresponding blade contacts can be placed in contact with each other and out of contact from each other by means of contact slide members which are displaceable along the row or rows of contact elements. The connector members can be positively coupled transversely of the direction of insertion by means of locking slide members. The contact slide members and the locking slide members are mounted on the same connector member and are in engagement with a common swivel lever mounted on the same connector member. The engagement between the contact members and the locking slide members is such that, during the coupling procedure as well as during the uncoupling procedure, initially only the locking slide members are movable and the contact slide members are movable subsequently.

Abstract: A region of the surface of the semiconductor (17) is illuminated with an intensity modulated beam of light (33,38), the wavelength of the light being shorter than that corresponding to the energy gap of the semiconductor (17). The surface photovoltage (SPV) induced in the semiconductor (17) is measured under bias voltage conditions (39). The intensity of the light beam and the frequency of modulation (38) are selected such that the surface photovoltage (SPV) is directly proportional to the intensity and reciprocally proportional to the frequency of modulation. Using the surface photovoltage (SPV) and the bias voltage (Vg) measurements, the charge induced in the semiconductor space charge region (Qsc) and the charge induced in the semiconductor (Qind) are determined. This information is used to determine various parameters of the semiconductor (17) including surface state density and oxide/insulator charge. The apparatus includes a reference electrode assembly (23) which in one embodiment includes a button of insulating elastomeric material and attached to a rigid plate of insulating material. A film (25) of insulating material having the reference electrode (23) at one face is pressed against the specimen with pressure sufficient to hold the reference electrode (23) in close compliance with the specimen (15), with pressure being applied from a backing contact (31). The ac photovoltage signal is capacitively picked up by reference electrode (23) and supplied through an amplifier (41) to a phase sensitive detector (43), the output of which is coupled through an A-D converter (45) to a computer (47).

Granted: 1995-06-28
Abstract: In a communications system having transmissions containing certain information-of-interest (147, 149) at predetermined intervals in the transmission, there is provided a method for isolating and processing that information-of-interest. The method is characterized by sensing the start of a transmission (141) and isolating for processing as the information-of-interest, the information received about instant(s) predeterminally removed in time (145) from the sensed start of transmission (141). Thus, the information-of-interest is isolated principally on the basis of elapsed time. The method for isolating and processing that information-of-interest is further characterized by sensing (249) the start of a transmission from the received signal power of the transmission exceeding a predetermined threshold (259); AGCing the transmission (233) and attenuating the AGC'd transmission from a maximum level to a desired level before the information-of-interest is expected to arrive; isolating for processing as the information-of-interest, the information received about instant(s) predeterminally removed in time from the sensed start of transmission, by timing (263) the expected interval between the instant that the start of the transmission is sensed and the predetermined instant that the information-in-interest should arrive (whereby the information-of-interest is isolated principally on the basis of elapsed time); tagging the information (247) isolated about that instant for processing; and beginning processing (275) with information just preceeding the isolated information (whereby the reliability of the information detection is enhanced by one-to-several bits). <IMAGE>
