Title: Distance-measuring device for camera
Inventor: ITO SHINSUKE
IPC: G03B13/36
Filed: 1994-03-18
Abstract: PURPOSE:To obtain the distance measuring device in which the adjusting operation of the electric characteristic of an amplifier system is not required. CONSTITUTION:Preamplifiers 30a, 30b, gain control circuits 31a, 31b, sample-and- hold circuits 32a, 32b, buffers 33a, 33b and main amplifiers 34a, 34b are connected individually to output terminals 9a, 9b for a PSD(position-sensitive device) 9. A microcomputer 14 reads out pieces of distance measured data AFD1, AFD2 by means of an A/D converter 15. When their value is improper, the value of a gain is changed via a control circuit 35 and a gain controller 36. The maximum value and the minimum value of the gain are written into an EEPROM 29 via a terminal device 28 for every camera. When the gain is controlled, the maximum value and the minimum value of the gain stored in a RAM 43 from the EEPROM 29 are referred to. Data which decides the timing of a sample-and-hold operation and a factor which corrects the difference in a gain between channels are stored in the EEPROM 29.

Abstract: PURPOSE:To pass and intercept light with short optical path length and to facilitate the adjustment of the optical axis of the input light by bringing a lens sphere into contact with the flank of a substrate under an electrode for heating the substrate and guiding in light to be modulated. CONSTITUTION:When a current accompanying a modulating voltage of 60V from a power source 6 to the electrode 3 for substrate heating is cut off by a switch 7, the spherical lens 1 arranged at the light input part diverges the light in the substrate 2 and when the current flows, on the other hand, the input light having passed through the spherical lens 1 reaches the light output part as it is through the light waveguide layer under the electrode 3. Consequently, the light is modulated. In this case, an input lead electrode 4 for voltage application and an output lead electrode 5 for voltage application are formed by sputtering at the same time with the electrode 3; the linear width of the contact between the electrodes 3 and 4 or 5 is 2-200mum and the angle theta of the spread at the part where the linear width between the electrodes 3 and 4 varies continuously is 35-36 deg..
