There is provided an optical modeling apparatus that forms a model of a desired shape by sequentially forming hardened layers by irradiating a light curable resin with light. The apparatus includes a first light source that emits a light beam for plotting on the resin, a scanning device that scans the light beam from the first light source over the resin, a second light source that emits light that irradiates one fixed region of the resin at a time, a spatial light modulator that spatially modulates the light from the second light source and blanket-exposes a specified region of the resin, and an exposure position adjuster that moves, in at least one direction, the light from the spatial light modulator. The light beam from the scanning device and the light from the spatial light modulator form each hardened layer.

The present invention provides an improved surgical blade and trocar system for accessing the retina and other parts of the eye while doing vitreo-retinal and cataract surgeries, including surgeries for macular degeneration. The eye surgeon uses an improved surgical blade for vitreo-retinal and cataract surgeries having a generally flat, V-shaped, W-shaped, or “extended W” shaped cross-section. Using the improved surgical blade, the surgeon creates a multi-planar, self-sealing surgical wound, first by directing the surgical blade substantially perpendicular to the eye surface, then redirecting the blade to follow the general curvature of the eye globe, and finally redirecting the blade to enter the interior of the eye. The improved surgical blade is used with an improved trocar system having two main parts-a relatively rigid, wide-mouthed outer segment and a generally thin-walled, collapsible plastic polymer or metal mesh sleeve that spans the surgical wound and substantially molds to its contour. The improved surgical blade and trocar system can be adapted for use in either vitreo-retinal or cataract surgeries.

There is provided a polarization maintaining optical fiber coupler and a method of manufacturing this polarization maintaining optical fiber coupler in which manufacturing is simplified and excess loss is reduced. A polarization maintaining optical fiber coupler is provided in which, in at least one of the polarization maintaining optical fibers forming the fused and extended portion, the ratio of the [diameter of the core/the diameter of the cladding] or [the distance between the two stress applying portions/the diameter of the cladding] is greater than the ration of the [diameter of the core/the diameter of the cladding] or [the distance between the two stress applying portions/the diameter of the cladding in the portions of the polarization maintaining optical fibers that do not form the fused and extended portion]. In addition, in this polarization maintaining optical fiber coupler, in the fused and extended portion, the stress applying portions are enveloped by the cladding. Moreover, polarization maintaining optical fibers are used in which the distance between adjacent outer circumferences of the two stress applying portions is 20 μm or more.

To anchor a fixture in a jaw bone, the fixture is applied in a hole which is substantially smaller than the diameter of the fixture. The fixture has a front portion which from the point of view of diameter grows very much narrower and which is arranged with both a cutting function and a threading function. The fixture is provided with a thread, with one, two or more thread turns extending down along the greatly narrowing portion while substantially maintaining their thread profile. One or more porous layers arranged on the thread turns can also be included. In this way the fixture can exploit the clamping effect from the soft parts of the jaw bone and still effectively penetrate through any hard parts possibly present in the jaw bone, without these hard parts being pressed inward upon fixture application. An effective fusion of the fixture in the jaw bone is achieved with the aid of said porous outer layers.

The outer ring is made of elastic material, and the inside of the lower portion of the outer ring has an inwardly protruding ring. The protruding ring is clamped to the connecting portion of the inner ring. In operation, one intestine is sleeved and fixed on the flange of the anastomosis portion of the inner ring, and the outer ring is overturned to let the lower edge overturn. Then another intestine is sleeved and fixed on the outer ring, and both the outer ring and the intestine are overturned so that the intestine is connected in the inner edge of the outer ring. Finally the inner ring is inserted and the two intestines overlapped on the anastomosis portion of the inner and outer ring.

A method of manufacturing a head of an inkjet printer includes forming a heater on a substrate and also forming an ink feeding passage through the substrate in a vertical relation to a surface where the heater is formed, forming an ink chamber communicating with the ink feeding passage of the substrate; attaching the substrate to the nozzle plate, and forming a tapered nozzle in the nozzle plate, the tapered nozzle being narrower in diameter in an inside of the nozzle plate than an outside of the nozzle plate, by radiating a laser beam from inside toward the outside of the nozzle plate, wherein the substrate is used as a mask. Since the nozzle is formed by radiating the laser beam to the nozzle plate through the ink feeding passage of the substrate after attaching the nozzle plate to the substrate, the accuracy of the nozzle in form and position improves, and the nozzle of desirable structure of the improved ink discharge efficiency can be obtained by radiating the laser beam only once. Also, the manufacturing process becomes simpler, and due to improved manufacturing process, the productivity increases.
