Date Oct. 27, 1983.In order to have with an integratable solid state relay a galvanic isolation between the control and the switch similar to that of a mechanical relay the control is performed via DC/DC-converters in a classical voltage-doubler circuit configuration. The switch function is provided by a pair of complementary MOS-transistors (Tr1 and Tr2) the gate/source capacitances (Cgs) of which are used as charging capacitances of the DC/DC-converters. In order to have a perfect blocking of the MOS-switches two DC/DC-converters (C1,C2,D1,D2,Cgs; C3,C2,D3,D5,Cgs) are provided which are controlled by two signals in the phase opposition so that for both switching states the same noise margin capability and the same switching-over times result. The circuit arrangement includes only diodes, MOS-transistors and capacitances (C1,C2,C3) of very small value which can be integrated without any difficulties.

Granted: 1988-03-31
Abstract: An encapsulated photoelectric measuring system for measuring the relative position of two objects includes a housing which encloses a scanning unit positioned to scan the graduation of a measuring scale. The housing defines a longitudinal slit closed by sealing elements, and a coupling member passes between the sealing elements and connects the scanning unit with one of the objects to be measured. In order to avoid optical disturbances of the beam path of the photoelectric scanning by liquid drops on the measuring scale, the scanning unit is hermetically sealed. The spacing between the surfaces of the scale acted upon by the light beams and the associated surfaces of the scanning unit is made so small that any liquid drops present on the surfaces of the scale in the region of the scanning unit are spread or formed into a continuously homogeneous wetted liquid layer.

Abstract: A scanning unit comprises offset scanning gratings and light receivers disposed behind respective gratings. The scanning unit is moved past an incremental scale and the receivers are illuminated through the scale and the gratings. Carrier frequency signals which are displaced in phase and are amplitude-modulated in dependence on the pitch of the scale are generated in response to the scanning movement. The phase displacement of the modulation of the carrier signal is evaluated to determine the instantaneously scanned fraction of a scale increment in that a proportional number of clock pulses are counted by a counter. The use of a simple and reliable circuit arrangement and a reliable evaluation are permitted in that the illumination is modulated at the carrier frequency so that the light receivers constitute means for effecting an amplitude modulation of the carrier frequency signal. The amplitude-modulated signal is then processed further. The modulating signals corresponding to full scale increments may be separately detected and may be used to detect the direction of the scanning movement and to measure the full scale increments which have been scanned.
