Title: Method for corneal laser surgery
Inventor: JUHASZ TIBOR
IPC: A61F9/01
Filed: 1999-03-31
Granted: 2003-11-18
Abstract: A method for corneal laser surgery includes directing the focal point of a focused laser beam at a start point in the stroma. The focal point is then moved along a predetermined path (92) in the cornea to photo disrupt tissue, and to create a flap or a plug of corneal tissue. Specifically, the flap or plug (72) is crated with an undercut region (74) that interlocks with an overlay region (76) to restrain movement of the flap or plug in an anterior direction. Stromal tissue under the flap or plug can then be, removed (36) when the plug or flap is forcibly lifted from the cornea. The flap or plug is subsequently replaced in its interlocking relationship with the remainder of the cornea tissue. The diminished stromal tissue reshapes the cornea in a manner which improves the vision of the patient.

Abstract: A technique of the present invention uses dark yellow (DY) ink, in addition to a plurality of conventionally used basic color inks including cyan (C) ink, magenta (M) ink, and yellow (Y) ink. The technique may cause a printer to create dots with the DY ink, in place of creation of dots with the Y, C, and M inks. This arrangement enhances the degree of freedom in specification of dot on-off conditions of the respective inks, and relieves the restriction of ink duty, thereby enabling a resulting printed image to have higher picture quality.

Abstract: The shipping and/or retail package (1, 4) described here for and with food(s) (8) intended for heating in the package (1, 4) and for consumption while hot consists of a material suitable for use in a microwave oven, where the food (8) in the package (1, 4) is preferably at least partially raw, and where, taking into account the water content of the food (8), enough liquid is present in the package for the food (8) to be cooked in a steam atmosphere which develops in the package when heated in a microwave oven, and where the package includes a one-way non-return valve (5) in a wall (4), said valve opening automatically to the outside when there is an internal excess pressure, then closing again automatically after the pressure drops, thus limiting and/or reducing the vapor pressure that develops in the package when heated rapidly in a microwave oven. The valve is designed so that it changes when the food is heated in the package to the extent that it cannot close again subsequently, at least during an initial phase of cooling of the food to a temperature suitable for consumption. Therefore, no vacuum can develop in the package while it is cooling to the temperature for consumption, and the package cannot undergo any negative deformation.

Abstract: A histogram is generated by dividing pixels constituting multivalued image data loaded onto a RAM 3 into a plurality of levels. On the basis of the histogram, a level or levels are changed of at least part of the pixels of the multivalued image data. The level change enables control of the image quality of hard copy pictures. The multivalued image data, the levels of at least part of the pixels of which are changed, is converted into binary image data representing pseudo-gray levels. A printer prints the output binary image data. The hard copy picture formed on a recording medium by the printer reproduces the multivalued image data loaded onto the RAM 3 with high fidelity.

Abstract: Plant cutter apparatus includes a handling rod, a drive source unit mounted on one end portion of the handling rod via a clutch case, and a cutter blade mounted on the other end portion of the handling rod for being rotated by activation of the drive source unit. With the handling rod inserted in an axial loosely-fitting hole of the clutch case, the one end portion of the handling rod abuts at its end surface against an abutting region formed on the way through the loosely-fitting hole. The drive source unit is supported by the end surface of the handling rod via a drive-source mounting portion of the clutch case. The drive source unit is allowed to freely vibrate about the one end portion of the handling rod supporting the unit, so that a flexible coupling portion of the clutch case can perform a vibration attenuation function to reduce vibrations transmitted from the drive source unit to the handling rod.
