Patent EP-0044121-A2 (EP)
Inventor: WILKINSON RICHARD L
IPC: G11B7/12
Filed: 1979-03-27
Abstract: This invention relates to an apparatus and process for writing video information in the form of a frequency modulated signal upon a video disc member and for recovering the video information from the video record is described. The video disc member (10) formed by the writing apparatus is also described. The writing apparatus includes a laser (30) as a source of a laser write beam (29) and a write optical system (40) for directing the stationary laser write beam to a moving video disc member. The video disc member comprises a substrate member carrying a light responsive coating (26) at least one surface. The write optical system focuses the beam to a small spot of light approximately one micron in diameter upon the light responsive layer. The intensity of the focused spot is changeable under the control of a light intensity modulating assembly (44). This light intensity modulator changes the intensity of the write laser beam with respect to a predetermined threshold intensity sufficient to form a first type of indicia (37) in the coating. A read system (165) is employed to retrieve the video signal stored on the video disc member. This read system includes a read laser (150) for generating a read beam, and a motion control assembly for rotating and translating the video disc member relative to the read light beam. A read optical system directs the read beam to impinge upon the successively positioned specular light reflective and non-specular light reflective regions (37,38) carried by the video disc member. The read optical system also collects the light (150) reflected from these regions. The reflected light beam is intensity modulated by the specular light reflective and non-specular light reflective regions. The read optical system also directed the reflected light beam to a light sensing circuit for changing the intensity modulated reflected light beam to a corresponding frequency modulated electrical signal (165) which is representative of the video signal stored on the video disc member. Circuitry is described for using a triangular frequency modulator (Figure 14C) for driving a Pockels Cell (68) and for obtaining a sinusoidal-shaped light modulation output signal from the linear polariser (70). The output from the linear polariser is adjusted such that the half power point from the polariser equals the threshold power level of the material forming the information storage layer. A second harmonic bias circuit (264) is employed for removing the second harmonic intermodulation distortion of the modulated write beam.

Abstract: There is provided an induction motor control system in which speed control of an induction motor is effected in digital fashion through use of a computer but without complex processing, and with a computer that need not be large in scale. This is accomplished by processing at least a speed command signal (VCMD), actual speed signal (TSA) and torque signal (ER) in analog fashion, enabling simplification of an induction motor speed control digital processing section which performs all other control operations in a digital manner. In a speed control network having a closed loop, a frequency-to-voltage converter (14), adder-subtractor (15), proportional integrator (16), polarity discriminator (17), absolute value circuit (18) and voltage-to-frequency converter (19) are constructed of circuitry operable on the basis of analog values, with all other circuits being constructed of circuitry operable on the basis of digital values.

The two light sensitive elements (3a, 3b) are comprised of amorphous semiconductor and are electrically connected in series. On the other hand, the light-emitting elements (2a, 2b) are driven responsive to individual input signals, respectively. If and when two input signals are applied simultaneously, the two light-emitting elements (2a, 2b) emit light simultaneously, so that an output is obtained from the two light sensitive elements connected in series. If and when only one input signal is applied, no output is ob- talned. Thus, an optical logical product circuit is provided.
