Title: Measuring circuit of intensity of light detected with photosensor
Inventor: YOKOYAMA SHIYOUTAROU
IPC: G01J1/44
Filed: 1982-02-22
Abstract: PURPOSE:To widen the measuring range for the intensity of detected light, by connecting a prescribed voltage generating means through an another capacitor to a charging and discharging circuit in an exposure meter or the like consisting of a photosensor and a capacitor. CONSTITUTION:The following equation holds if V1=V2=0 is set in an initial state, the electric charges to be accumulated in capacitors C1 and C2 are defined as Q1, Q2, and the photoelectric current flowing in a photosensor 1 is defined as (i): V1=Q1/C1=Q2/C2+ f(t). More specifically, the input voltage V1 to an inverter 3 is expressed by the sum of the voltage by photoelectric current and the voltage generated by a voltage generating means 5 irrespective of the photoelectric current. The voltage by the means 5 increases monotonously and attains the threshold value Vth of the inverter 3 when a certain time passes by even if the current (i) decreases. In other words, even if the current (i) varies 10<3> between the max. and the min., the component by f(t) is dominant in the range where the current small, and the time when the voltage V1 attains the threshold value Vth is not so long. Thus, even if the intensity of the detected light changes over a wide range, the conversion time is kept within a practical range, and the dynamic range is widened.

Title: Solid spectroscope with groove
Inventor: HASUMI RITSUO
IPC: G01J3/18
Filed: 1979-03-05
Abstract: PURPOSE:To simplify connection works of a rod lens, an optical fiber, etc., by forming grooves, which hold the rod lens, the optical fiber, etc., on the wall face part corresponding to an incident entrance and an emission exit. CONSTITUTION:Diffraction lattice 2 and concave-face reflection mirror 3 are formed on the inside wall face of ceramic frame 1, and solid pickup element 5 is fitted to emission exit 4. V grooves 7 and 8 are formed in two steps at incident entrance 6, and rod lens 9 and optical fiber 10 are put in V grooves 7 and 8 respectively and are held. Light 11 propagated through optical fiber 10 is converted to a parallel light beam by rod lens 9 and enters from incident entrance 6 into cavity 12 and goes straight and is irradiated to diffraction lattice 2. Diffracted light 13 goes straight in cavity 12 and strikes concave-face reflection mirror 3 and is condensed in a position of emission exit. Thus, connection of the rod lens and the optical fiber to the solid spectroscope is simplified, and mass production of the same standardized goods is possible for the same metallic mold.

Further, a clock pulse of narrow width from a clock  generating circuit composed of resistances 24-26, TR16-19, etc., is supplied to  the clock input of the FF circuit, which performs toggle operation. Thus, since a  simple and fast gate circuit is used as the current change-over type logic circuit instead of using the D latch circuit, the delay time of this part lessens and faster  operation is put into effect.
