Abstract: A jig and a cooling fluid injection tool are provided for use in the correction of corneal shape of an eyeball. Correction of the eyeball takes place while the cornea is warmed. The jig includes a shape retention part of a sucking disc configuration having an inner surface side that contacts the eyeball and a grip part formed on an outer surface side of the shape retention part. An inner surface-sided cornea contacting section of the shape retention part is flattened and a cooling fluid injection hole passing through the grip part is formed in the center of the shape retention part with a diameter large enough for a wearer to see outside.

Abstract: A jig and a cooling fluid injection tool that are used in the correction of corneal shape conducted while the cornea of the eyeball is warmed and softened are provided. The vision corrective jig 1 comprises a shape retention part 2 of sucking disc configuration with its inner surface side contacting with the eyeball and a grip part 3 formed on the outer surface side of the shape retention part. The inner surface-sided cornea contacting section 2a of the shape retention part 2 is flattened and a cooling fluid injection hole 4 passing through the grip part 3 is formed in the center of the shape retention part 3. The cooling fluid injection hole 4 has a diameter being large enough for a wearer to see outside through the cooling fluid injection hole 4. The grip part 3 is integrally formed on the outer surface side of the shape retention part 2 in a button shape.

Abstract: The present invention provides a apparatus for correcting eyesight characterized in that a cornea pressure member is slidably attached to a cap-like cornea sucking member, and a cooling liquid injection channel is formed through the cornea pressure member. The cornea sucking member is further provided with an air sucking port and a liquid ophthalmic medicine injection port. The cornea sucking member is applied to a cornea which has been softened by being warmed by any known warming method; said member pulls the cornea forward by sucking air through the air sucking port; and in the mean time the cornea pressure member presses the cornea with its head portion so as to modify the shape of the cornea to a desired one. Immediately thereafter, a cooling liquid is passed through the cooling liquid injection channel to rapidly cool the cornea, thereby stabilizing the corrected shape of the cornea.

Abstract: An eye mask has magnetic bodies and self-heating warm members, which are inserted in eye pads on a mask member to be placed over eyeball parts. If required, vibrators and illumination bodies may be additionally placed in the eye pads. Thus, fatigue on the eyes and surroundings thereof can be relieved by the magnetic actions of the magnetic bodies and the warming effects of the warming member, in addition to expected effects of restoring ocular functions, recovering from various ocular diseases, and so on. Furthermore, the surface of each of the eye pads is gradually curved like the inner surface of a sphere. When the eye pads are press-contact to the eyeball parts at predetermined pressures for a long time, the cornea can be warmed by the warming members so that the shape of the cornea can be changed along the shape of the eye pad, resulting in the effects of recovering from eye sight disorder such as pseudo-myopia, moderate farsightedness, or moderate astigmatism.

Abstract: A cooking container has a dual structure composed of an inside container formed with a thin metal plate and an outside container formed with a thick metal plate. The heating and cooking surface of the inside container is finished with a fine porous surface by etching, and the heating and cooking surface is formed with many concaves and convexs by press forming, thereby enabling to avoid scorching and sticking of a material under cooking to this surface.

Abstract: A roll to be rotatably inserted within a juicer housing is formed in a brimmed spiral at an upper part thereof and in a coiled spiral at a lower part thereof, whereby raw juice is instantly made by a simplified mechanism and an easy operation.
