An intraocular lens insertion device having a novel configuration, capable of more accurately arranging front and back surfaces of an intraocular lens in a proper direction. The intraocular lens insertion device is adapted in such a manner that the intraocular lens is set on a stage in a state placed flat with a pair of haptics extended facing front and back sides in a movement direction by a plunger. Also, an interfering acting part is provided to an insertion tube part, and the interfering acting part interferes with the haptic, which is extended facing the front side in the movement direction of the intraocular lens moved by the plunger, to apply on the haptic an external force toward the back side in the movement direction. Thus, the interfering acting part curves and deforms the haptic to a side approaching an optical portion.

The present inventors successfully constructed expression vectors that enable high-level production of foreign gene-derived proteins in mammalian host cells, which comprise a translation-impaired drug resistance gene cistron whose expression has been attenuated by altering the codons to the least frequently used codons in mammals; and a gene cassette which has a cloning site for incorporation of a foreign gene between a highly transcriptionally active promoter and a highly stable polyadenylation signal.

摘要:
A method of producing a medical instrument whereby a highly hydrophilic and lubricant coating layer having a high durability can be formed by a simple technique and thus highly hydrophilic and lubricant properties can be imparted to a surface of a medical instrument. An intraocular lens insertion instrument having been subjected to a surface treatment as described above is also provided. The method comprises the steps of: preparing a coating solution by mixing at least a water-insoluble polymer having carboxyl group and a polyfunctional reactive compound with an organic solvent; applying this solution on the surface of the medical instrument; conducting crosslinking; and performing a chemical reaction process whereby the coating layer is made hydrophilic. The intraocular lens insertion instrument is made hydrophilic by forming the coating layer as described above on an inner surface of an insertion tube portion, crosslinking and then performing the chemical reaction process.
摘要:
A robot device, which autonomously performs actions, includes a moving unit that moves the robot device, and a target position acquiring unit that acquires position information of a target. A movement method judging unit receives an instruction for a movement from a user, and judges whether or not a destination can be designated by fixed position information. When it is judged that the destination can be designated by the fixed position information, control is performed by a position movement control unit. When it is judged that the destination cannot be designated by the fixed position information, control is performed by a target movement control unit, which acquires position information from the target position acquiring unit, to operate the moving unit.

To provide an image display apparatus that is allowed to incorporate a panel module with excellent mechanical strength even if a screen is upsized and the apparatus is slimmed down. Strengthening units are mounted along a horizontal direction on canopies provided on an upper portion and a lower portion of a panel module constituting a display unit of a large-size, thin image display apparatus. Also, supporting members are mounted on the upper and lower strengthening units in such a manner that the supporting members bridge between the upper and lower strengthening units, so that a stand, or a chain or a string to be used when hanging the image display apparatus is mountable to the supporting members. This prevents direct application of external force to the panel module.
