摘要:
This invention provides an ophthalmic measuring apparatus and an ophthalmic apparatus particularly for observation by retroillumination. The ophthalmic measuring apparatus is provided with an eye measuring system, an observing system enabling observation of the eye to be examined by the examiner, an anterior segment illuminating system and a control system. The ophthalmic apparatus is provided with an observing system enabling observation of the eye to be examined, an ocular fundus illuminating system, a time measuring means and a control system.

A position detecting apparatus for an ophthalmologic apparatus has an image pickup element, a light source, a first projection system for projecting a light beam from the light source onto the cornea of an eye to be examined, a second projection system for projecting one corneal reflection image of the light source onto a plurality of positions on the image pickup element, and a calculator for calculating the central positions of and the distance between the corneal reflection images projected onto the plurality of positions on the image pickup element. The positional deviation of the ophthalmologic apparatus relative to the eye to be examined from an aligned state is quantitatively detected by the calculation by the calculator.
摘要:
An ophthalmic apparatus includes a first index mark provided as an index mark for measuring the shape of a cornea substantially on the optic axis, a second index mark provided around the optic axis, and a calculator for calculating the shape of the cornea based on the position information of the cornea-reflected image of the first and second index marks.
摘要:
A mixture of three kinds of bacteria is disclosed which is useful for humans and animals. The symbiotic mixture contains as effective ingredients lactic acid producing bacteria, saccarificating bacteria, and butyric acid producing bacteria which are useful for human and animals. A method is disclosed for effectively cultivating a symbiotic mixture of these three kinds of bacteria by a cooperative action.
摘要:
A chain-type force transmission belt for engagement with a pulley, which transmission belt consists of a plurality of link plates, a plurality of pins connecting the link plates so as to define an endless flexible belt with at least one of the pins having a lengthwise axis and axially spaced first and second ends, a first tip member/block for placement in an operative position at the first pin end and having a first surface for engagement with a pulley, a second tip member/block for placement in an operative position at the second pin end and having a second surface for engagement with a pulley, and structure separate from the one pin for connecting the first and second tip members/blocks together for holding the first and second tip members/blocks in their operative relationship.
摘要:
An ophthalmic measuring apparatus has an ultrasonic detector for measuring the length of a predetermined region of an eye to be examined, a device provided with a center axis coaxial with the center axis of the vibrator of the ultrasonic detector and projecting an index mark onto the cornea of the eye to be examined, and an imaging optical system for forming the corneal reflection image of the index mark on a predetermined image plane to measure the shape of the cornea.
摘要:
In a cornea shape measuring apparatus wherein a chart for measurement is projected onto the cornea of an eye to be examined and the shape of the corneal reflection image thereof is detected through a measuring optical system to thereby measure the shape of the cornea, there is provided an observation optical system for enabling the corneal reflection image to be always observed. The magnification of the observation optical system is made smaller than the magnification of the measuring optical system and the fore eye portion and the corneal reflection image are always observable.
摘要:
A stereoscopic microscope is provided with a single objective lens and a pair of eyepieces disposed rearwardly of the objective lens. A pair of interpupillary distance adjusting means and a pair of refraction type vergence adjusting means are disposed between the objective lens and the eyepieces.
摘要:
In a system in which the polarity of the frequency converted chrominance signal or carrier is reversed during alternate lines of alternate fields recorded on alternate tracks on a recording medium and not reversed during the lines that make up the remaining alternate fields recorded in h-alignment on the remaining alternate tracks positioned in interleaving relationship with the first-mentioned tracks, logic-controlled switching means are provided to select the field intervals during which the plurality of the chrominance subcarrier will be reversed in alternate lines. The same logic circuits can be used to control the switching during both recording and reproducing so that the alternate plurality reversal of the chrominance subcarrier will take place during the proper fields during reproduction of the recorded signals. Furthermore, the flip-flop that controls the switching circuit to reverse polarity of the chrominance signal or carrier is, itself, controlled to start always in the correct polarity in those field intervals when it is operative.
