Title: Optometric apparatus
Inventor: KOBAYAKAWA YOSHI
IPC: A61B3/10
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To achieve a compact structure of an optical system by miniaturizing it. SOLUTION: Light sources 21a-21d for measuring cornea project light fluxes to a cornea from outside a light splitting member 1. Images as those reflected on the cornea of the light sources 21a-21d projected onto an area sensor 7 are taken into an arithmetic means and the positions of the cornea reflection images are computed to determine the radius of curvature of the cornea or to obtain information for positioning. In a dioptric measurement system, the distance to eyes E to be examined from an objective lens 8 of a measuring optical system and an objective lens 2 of a target optical system affects the size of the optical system as a whole.  But the projection of the light fluxes from the cornea measuring light sources 21a-21d made from outside the light splitting member 1 enables arrangement of the light sources 21a-21d and the measuring optical system in layers thereby achieving a miniaturization of the optical system as a whole with a shorter distance to the eyes E to be examined from the objective lenses 2 and 8.

Filed: 1984-07-27
Abstract: PURPOSE:To maintain a thermal balance, and to reduce a thermal distortion by varying a collctor - emitter voltage, when a gain setting current has been varied. CONSTITUTION:In a differential amplifier consisting of a pair of emitter coupling transistors TR10, 12, the emitters of both the TRs are connected to a voltage source VEE through a variable current source 14. A gain controlling circuit 26 supplies a gain control voltage VCC to this current source 14 and changes a set value of a current IT, by which the gain of the differential amplifier is set. Also, the circuit 26 generates a voltage which is proportional to an absolute value of the gain control voltage, and applies it to a cathode of diodes 16, 18. A voltage drop of the diodes 16, 18 is equal to a base - emitter junction voltage, therefore, its absolute value VD becomes equal to an emitter voltage VE. Accordingly, when the current IT is varied, the voltage VE is also varied proportionally, and a thermal balance is maintained at all gain positions.
