摘要： An automatic tuning scheme for use in TV receivers includes a start/stop circuit which creates a search start signal and a search stop signal upon the receipt of a search start instruction and a detected incoming signal, respectively, a tuning voltage generator which generates a gradually varying tuning voltage under control of the search start signal and search stop signal, and a memory circuit for storing the tuning voltage from the generator when desired. The tuning voltage stored in the memory circuit is supplied to a tuner including a well known voltage-sensitive capacitance diode.

摘要： A television signal determination circuit is associated with an automatic tuning system, which automatically tunes a television set to local channels, in order to determine whether received signals are desired television signals. The television signal determination circuit comprises a first counter means for counting received synchronizing signals for a predetermined period of time, a second counter means for counting reference clock signals for the predetermined period of time, and a determination means for determining whether the synchronizing signals are received by a predetermined number within the predetermined period of time by comparing output signals from the first and second counter means.

摘要： An ophthalmologic apparatus has a projection system provided with a fixation object capable of being perceived by an examinee, the projection system being for projecting the fixation object upon a desired position on the fundus of an eye to be examined. The apparatus further has an observation system for observing therethrough a portion of the eye to be examined, and a reflecting system disposed between the fixation object and the eye to be examined for directing a light beam emitted from the fixation object to the observation system. In the reflecting system, the light beam emitted from the fixation object and incident on the reflecting system is substantially coincident with a light beam reflected thereby.

摘要： Apparatus herein disclosed comprises a photographing system having an optical system of variable magnification and an illumination system having a light source for photographing and a light source for observing. In the apparatus, the existing photographing magnification of the optical system is detected and the quantity of light incident upon a film or a finder visual field is controlled depending upon the detected magnification so as to obtain an optimum exposure to the film of the photographing system or to maintain the brightness of the visual field constant. To attain the control of quantity of light, light passing through the illumination system or light passing through the optical system is gradually reduced with widening of the angle of field. Alternatively, intensity of light emitted from the light source for observing or light emitting time of the light source for photographing is altered depending upon the detected magnification.

摘要： The present invention relates to an eye bottom camera which is so designed that in order to eliminate the undesired light beam reflected by the objective lens opposed to the eye to be inspected the objective lens as one group of biconvex type whereby by making the undesired light beams reflected on both surface of the objective lens as if they were produced by a light beam emitted from a same plane of the illumination optical system the small black spot provided on the same plane can be made small and further by so designing that the image formed in the neighborhood of the objective lens, of the small black spot appears at the position closer to the eye to be inspected than the surface of the objective lens it is made difficult that the small black spot be formed on the eye bottom to be inspected.

摘要： An ophthalmologic apparatus can measure the eye axis length of an eye to be examined and other information of the eye to be examined (for example, the cornea refractive power). In the case of the measurement of the eye axis length, when moving a detecting terminal itself by driving means, the driving means is controlled so as to slow down the speed of movement of the detecting terminal when the detecting terminal comes near the cornea of the eye to be examined.

摘要： The corneal reflection virtual image of an index mark for cornea shape measurement is displaced by a variation in the working distance, but a light beam regulating device for extracting the corneal reflection light whose principal light ray is a light ray corresponding to the direction of displacement thereof is provided at a particular position in a cornea shape measuring optical system to thereby eliminate any measurement error based on the variation in the working distance. When a different region of the cornea is to be measured with the index mark displaced in the direction of the optic axis, a predetermined principal light ray conforming to the position of the index mark in the direction of the optic axis is caused to enter the light beam regulating device.
