摘要： A full wave rectifier comprises an input terminal supplied with an AC signal and an output terminal for delivering a rectified DC signal. An operational amplifier having an inverting input terminal, amplifies the AC signal. A rectifier gain setting is provided by a first resistor connected between the input terminal and the inverting terminal of the amplifier. A second resistor, having the same resistance as the first resistor, is connected between the inverting terminal and output terminal of the amplifier. A depletion type MOS FET operates responsive to the output of the amplifier, for performing a switching operation.

摘要： In a switched capacitor filter of a first-order responsive to a filter input signal for producing a filter output signal by carrying out sampling operation at a predetermined sampling rate by the use of switching circuit, a capacitor, and an integrating circuit, a voltage divider produces a voltage divided signal in response to the filter input signal to reduce a total capacitance determined by capacitances of the capacitor and the integrating circuit. The voltage divided signal is sampled by the switching circuit to be sent to the integrating circuit at the sampling rate through the capacitor. The integrating circuit produces the filter output signal as a result of integration. In addition, an additional switched capacitor filter of a first-order is connected in cascade to the filter to form a switched capacitor filter of a second-order. The additional filter comprises an additional voltage divider for voltage dividing an output signal of the additional filter to deliver an additional voltage divided signal to the filter and the additional filter.

摘要： An automatic system for inspecting products having an edge or edges which, for an acceptable product, are straight (within predetermined tolerances) without accurate orientation of such products which includes a raster-scanned television camera (or its equivalent) for generating a composite video signal corresponding to the product being inspected. The number of horizontal sweep intervals in each edge to determine its length and comparing such length information with pre-stored reference length to determine if the two correspond, rejecting the capsule if it is shorter than the reference length but, if it is longer than the acceptable length, determining if the greater length is a result of the product's being tilted or torn.
