摘要： Auxiliary seals are provided on a surface of a first metal separator, between load receivers and an oxygen-containing gas supply passage, a fuel gas supply passage, an oxygen-containing gas discharge passage, and a fuel gas discharge passage, in relatively wide areas. The cross sectional shape of the auxiliary seal is the same as those of a flow field seal and ring-like seals, and the auxiliary seals are formed independently from the flow field seal and the ring-like seals.

摘要： Ophthalmoscopic instrument having working position detector. An object lens has an optical axis and is adapted to be positioned to confront a patient's eye at a working distance. The patient's cornea has a center of curvature. An observing optical system focuses a light beam reflected from the eye and passing through an objective lens on an image plane. A detecting system detects that the eye is properly positioned with respect to the objective lens. The detecting system includes at least two apertures allowing light beams from a single target mark to pass therethrough. A target mark projection system projects the beams passed through the respective apertures in directions crossing each other on the optical axis of the objective lens so that a target mark image is formed at the center of curvature of the cornea when the eye is properly positioned with respect to the objective lens. A target mark image plane forms a target mark image by mirror reflection from the cornea of the light beams projected through the target mark projection system when the patient's eye is properly positioned, and a target mark image observation system provides observation of the target mark image on the target mark image plane in superposition with a reference mark.

摘要： A working distance detecting device for ophthalmic instruments has two annular slits in the illuminating system. One of the annular slits has a light-shading portion of a predetermined width. A light-receiving portion is provided around the object lens so as to receive beams of light reflected at the cornea of the eye to be examined. The working distance can be detected at the light-receiving portion by the image of the light-shading portion of the annular slit.

摘要： An eye fundus camera is disclosed having a working distance detecting device. The eye fundus camera includes an illuminating system having a ring-shaped aperture through which the illuminating light beam is projected to the eye to be examined through an objective lens. The working distance detecting device includes an opaque portion formed in said ring-shaped aperture and having a width in circumferential direction. A light receiving portion is provided around the objective lens at a position corresponding to the opaque portion in the image of the ring-shaped aperture formed by beams of the illuminating light reflected from the cornea of the eye so that the working distance can be detected based on the width of the opaque portion of the image of the ring-shaped aperture.

摘要： An eye fundus camera including an illuminating system having two apertured masks. One of the masks has a pair of coaxial ring-shaped slits and located with respect to the objective lens in conjugate with the cornea of the patient's eye, whereas the other has a ring-shaped slit in conjugate with the iris of the eye. The arrangement is effective to provide an increased field angle with a substantially uniform illumination without having adverse effects of harmful reflections.

摘要： A focus detecting device for an eye fundus camera including a target having a target pattern comprised of a first slit and a second and third slits disposed in parallel with and at the opposite sides of the first slit. The second and third slits are symmetrical to each other with respect to the first slit. Deflecting prisms are provided to deflect the luminous flux through the first slit in one direction perpendicular to the longitudinal axis of the first slit and the luminous fluxes through the second and third slits in the opposite direction. The slit pattern is convenient for automatic focus adjustment.
