Patent JP-S5915310-A (JP)
Title: Frequency modulating circuit
Inventor: ASHINO WATARU
IPC: H03C3/09
Filed: 1982-07-17
Abstract: PURPOSE:To stable the carrier frequency, by correcting the oscillating frequency while no modulated signal is supplied and having a control so that the corrected frequency is maintained as a center frequency even when the modulated signal is supplied. CONSTITUTION:Switches 2 and 9 are turned off and on respectively with a switching signal W. Then the output of a voltage control oscillator 5 is compared with that of a reference oscillator 7 by a phase controller 6. Those compared outputs are connected to the control input terminal of the oscillator 5 through a filter 8 via a buffer part 10. Under such conditions, the oscillating frequency of the oscillator 5 is corrected to the frequency of the oscillator 7. When the switches 2 and 9 are turned on and off respectively with the signal W, a modulated signal S is applied to the control terminal of the oscillator 5. In this case, the output voltage of the filter 8 obtained during correction is held at a capacitor 11 and then applied via the buffer 10. Therefore a carrier frequency is equal to the frequency of a reference signal.

Title: Optical guiding device of travelling object
Inventor: NISHI YOUKICHI
IPC: B61B13/00
Filed: 1984-06-18
Abstract: PURPOSE:To miniaturize an optical guiding device of a traveling object and also the drive the traveling object correctly along a driving route, by using a large-size light spot position detecting element using an amorphous semiconductor layer at a photoelectric conversion part to detect the position of the traveling object, detecting a shift of the traveling object from the reference driving route and performing the steering control for correction of said shift. CONSTITUTION:When a light beam B is made incident on a light spot position detecting element 5, an excess carrier is produced to a p-n junction at an irradiation point l of the beam B. A current obtained from the excess carrier flows between a common electrode 18 and the 1st and 2nd electrodes 16 and 17 respectively via the 1st transparent conductive film 14. Then iA/iB=(L-x)/x is satisfied between currents iA and iB flowing to the electrodes 16 and 17 respectively, where L is the distance between electrodes 16 and 17, R is the full resistance R of the film 14 between both electrodes 16 and 17, I is an optical current produced by the incident light and (x) is the distance between the point l and the electrode 16 respectively. The element 5 uses an amorphous semiconductor layer to a photoelectric conversion layer. The output signal obtained by amplifying the output signal of the element 5 is compared with a signal showing the reference value to calculate 8 a shift from the reference position. The steering control 10 is carried out to eliminate said shift.
