Abstract: A method and clip for treating presbyopia and/or open angle glaucoma in which the sclera is supported or reinforced, while substantially maintaining the special relationship between the ciliary muscle and the lens. The method includes making an incision in the conjunctiva to gain access to the sclera overlying the ciliary muscle. The Tenon's capsules are moved laterally to expose the sclera, and the sclera is extended outwardly. A clip, or series of clips, is provided having two closeable arms for engaging the outwardly-extended sclera therebetween. The arms of the clip are closed on the sclera so as to grasp a portion of the sclera, and then the Tenon's capsules are slid over the clip and the conjunctiva is closed.

Abstract: A gate metal is formed in a film, the foregoing gate metal is partially etched per each TFT having a different property, and a gate electrode is fabricated. Specifically, a resist mask is fabricated by exposing a resist to light per each TFT having a different property which is required. A gate metal is etched per each TFT having a different property which is required using the foregoing resist mask. At this time, a gate metal covering a semiconductor active layer of a TFT except for the TFT during the time when the patterning of a gate electrode is performed is left as it is covered. The step of fabricating a gate electrode of each TFT may be performed under the conditions optimized in conformity with the required property.

Abstract: By providing appropriate TFT structures arranged in various circuits of the semiconductor device in response to the functions required by the circuits, it is made possible to improve the operating performances and the reliability of a semiconductor device, reduce power consumption as well as realizing reduced manufacturing cost and increase in yield by lessening the number of processing steps. An LDD region of a TFT is formed to have a concentration gradient of an impurity element for controlling conductivity which becomes higher as the distance from a drain region decreases. In order to form such an LDD region having a concentration gradient of an impurity element, the present invention uses a method in which a gate electrode having a taper portion is provided to thereby dope an ionized impurity element for controlling conductivity accelerated in the electric field so that it penetrates through the gate electrode and a gate insulating film into a semiconductor layer.

Abstract: The present invention has an object to provide a semiconductor device, an ID tag, in which delay of signal transmission with conductive layers is controlled. In addition, the other object is that a design method of such a semiconductor device is provided. A semiconductor device of the invention comprises a plurality of conductive layers, a plurality of first element groups each of which selects one among the conductive layers and a plurality of second element groups each of which amplifies a signal each transmitted from the conductive layers. Each of the second element groups is disposed between the first element groups. Stated another way, the first element group and the second element group are disposed alternately. The delay of the signal transmission with the plurality of conductive layers is controlled because a load by a parasitic capacitance is reduced due to the above feature.

Abstract: A filtration medium is sealed within a housing. The filtration medium is sized and configured to define multiple filtration regions within the housing, through which independent, though concurrent, blood filtration can occur. Each filtration region is served by its own inlet path, which conveys blood into the filtration region. The filtration medium in each filtration region passes the blood to remove at least one undesired component, such as, e.g., leukocytes. After filtration, the multiple filter regions convey the blood into a single, centrally located manifold. A single outlet path communicates with the manifold.
