    • A solid state relay comprises a light-emitting diode (2) for generating radiation in response to forward current supplied thereto and an array (5) of photodiodes optically coupled to the light-emitting diode for generating a voltage in response to radiation from the light-emitting diode. A thyristor (18) is provided having anode and cathode coupled to the gate and substrate electrodes (11a, 11b, 14a, 14b) of a field-effect transistor, respectively. A gate electrode (21) of the thyristor is connected to one end (7) of the photodiode array (5) and the cathode of the thyristor is further connected to the other end (8 ) of the photodiode array. The voltage generated by the photodiode array is applied to the switching transistor (9, 10) through a diode (17) so that the impedance between the source and drain electrodes of the transistor has a low value in the presence of the voltage and a high value in the absence of the voltage. A voltage photogerated by the array in response to radiation from the light-emitting diode forwardly biases the diode (7) and backwardly biases the thyristor, so that it is applied to the transistor without loss of energy. Upon cessation of the radiation, a voltage difference between the photodiode array and the transistor backwardly biases the diode (7) and forwardly biases the thyristor, providing a low impedance path for rapidly discharging energy stored in the transistor to cause it to turn off.

    • A cleaning device for magnetic tape heads comprises a mylar tape on which is deposited a layer of a low-tack adhesive. A dacron fabric is bonded to the mylar tape by the adhesive layer. This dacron tape acts as a mechanical cleaning surface when it is moved across the contact surface of the tape head. The adhesive layer operates both to secure individual strands of the fabric rigidly in place so as to support the strands properly when they are in contact with the tape head, and also to capture and control the movement of magnetic particles dislodged from the tape head by the strands of the fabric. Alternate embodiments provide ridges for defining a pattern of raised projections extending away from an underlying base.
