Abstract: An intraocular lens insertion instrument includes: a cylinder (10, 20, 60) provided with an insertion part (11) which is inserted in an eye through an incision formed in the eye; a push-out unit (30) which is mounted axially movably in the cylinder to push out an intraocular lens (40) placed in the cylinder to the outside through the insertion part; and a working pressure adjustment unit (22, 23, 24; 70, 72, 80, 81) which is set in contact with the push-out unit to adjust working pressure needed to move the push-out unit by changing frictional force on the push-out unit.

Abstract: An intraocular lens injector for injecting a foldable intraocular lens in an aye, comprises: a substantially cylindrical main unit including a substantially cylindrical insertion part which is insertable through an incision made in the eye, the main unit being adapted to internally hold the intraocular lens and release the intraocular lens to the outside of the injector through the insertion part; a push unit inserted in the main unit to push the intraocular lens to the outside through the insertion part, the push unit being disposed to be unrotatable relative to the main unit but movable in an axial direction of the main unit; and a rotatable member disposed to be rotatable relative to the main unit.

Abstract: An ultraviolet absorbing base material is disclosed in which a vinyl copolymerizable monomer and a benzotriazole ultraviolet absorbing monomer represented by formula (I) or (II) are copolymerized: ##STR1## wherein X represents H or a halogen, R.sub.1 is H or an alkyl group having 1 to 6 carbon atoms, R.sub.2 and R.sub.3 each represents a linear or branched C.sub.1 -C.sub.10 alkylene group and R.sub.4 represents H or CH.sub.3.

Abstract: A slit lamp microscope is of the type having an illumination optical system for illuminating the eye to be examined, an observation optical system for observing the illuminated eye to be examined and a photographing unit. The slit lamp microscope comprises exposure control unit for controlling exposure at the time of photographing, a photographing conditions designation arrangement for designating at the time of photographing at least the designation of a part to the eye to be photographed and conditions regarding system of photographing, and an optimal exposure calculation unit for calculating an optimal exposure in accordance with the designated photographing conditions. The exposure control apparatus controls the exposure in accordance with the value of exposure calculated by the optimal exposure calculation unit when the photographing conditions are designated by the photographing conditions designation means.

Abstract: An ophthalmic photographing apparatus comprises an illumination optical system for illuminating an eye to be tested, a viewing optical system having a variable magnification optical system for viewing the illuminated eye to be tested, and a photographing device detachably mounted on the viewing optical system. A position change of a predetermined part due to the change of magnification of the variable magnification optical system is measured to produce a signal representing the displacement. The signal representing the magnification of the variable magnification optical system is used to control an intensity of a flash light.

Abstract: A vehicle door mounting system mounts a door on a vehicle body by bringing a hinge member on the door into engagement with a hinge member on the vehicle body and inserting a hinge pin into hinge pin holes of the hinge members. The mounting system has a robot, and a door holding jig and a hinge pin inserting jig which are mounted on the robot. The robot is arranged so that it brings the door to a predetermined position with respect to the vehicle body where the hinge member on the door is engaged with the hinge member on the vehicle body while the door holding jig holds the door. The hinge pin inserting jig is separable from the door holding jig and is moved between an operative position where it inserts the hinge pin into the hinge pin holes and a hinge pin setting position where the hinge pin is set to the hinge pin inserting jig.

Abstract: An automobile assembling apparatus is provided to provisionally assemble a set of front and rear drive system assemblies, each having at least a suspension system with a damper unit dangling thereon, to a vehicle body prior to rigidly securing, and thereby setting up, the front and rear drive system assemblies and vehicle body into one unit with fasteners in an automobile assembling line and comprises a carrier pallet for carrying the set of front and rear drive system assemblies placed thereon in position, a conveyor for conveying the front and rear drive system assemblies on the carrier pallet to a provisional assembling station wherre front and rear drive system assemblies are provisionally assembled to vehicle bodies, an overhead conveyor for conveying the vehicle body above the provisional assembling station and lowering it on the front and rear drive system assemblies to provisionally assemble the front and rear drive system assemblies to the vehicle body, and a holding device installed at the provision

Abstract: A door assembling apparatus for use in automobile assembly having a door transport unit for conveying a door and for maintaining a hinge member of a vehicle body and a corresponding hinge member of a door loosely engaged with each other, a hinge-pin attaching unit for inserting a gib-headed hinge pin through the engaged hinge members, and a stopper for receiving a leading end of the hinge pin as being projected from and through the engaged hinge members. The leading end of the hinge pin increases in diameter through plastic deformation thereof by the contact with the stopper, and this increased diameter effectively prevents disengagement of the pin from the hinge members. With these features, the anti-disengagement operation can be effected very efficiently and conveniently through the plastic deformation of the leading end of the pin which is realized by effectively utilizing the original function of the hinge-pin attaching means, i.e. the function for causing the hinge pin to enter the hinge members.

Abstract: An apparatus for assembling a wheel attaching unit for use in a vehicle assembly line having a pallet capable of mounting at predetermined positions thereof a front assembly including a front wheel attaching unit and a rear assembly including a rear wheel attaching unit; a pallet conveyor for conveying the pallet through a setting area and a securing area of the front and rear units and a body; and a body conveyor for conveying the body to a position above the setting area and for lowering the body to set the front and rear assemblies to the body. The pallet includes a holding portion for the front assembly and/or a holding portion for the rear assembly with the holding portion being position adjustable in forward and rearward directions thereof.

Abstract: A method of mounting parts to both sides of a main body characterized by moving a carriage at a predetermined speed along a specified path of transport with the main body placed on the carriage; moving a pair of movable tables in synchronism with the carriage in the same direction as the movement thereof, the movable tables being disposed at opposite sides of the transport path and each carrying at least one robot and an assembling device; causing the movable tables to support the main body during the synchronized movement; setting a part held by the robot in a specified position on the main body; attaching the part to the main body by the assembling device; and thereafter delivering the main body from the movable tables onto the carriage. Since the carriage is moved during the assembly of parts, this method assures the assembly line of a high-speed operation.
