Abstract: A surgical device for cutting substantially across a cornea of an eye of a patient, the device including a positioning ring structured to be temporally attached to a portion of the eye surrounding the cornea to be cut, and defining an aperture sized to receive and expose the cornea to be cut. The surgical device further includes a cutting head assembly structured to be guided and driven over an upper surface of the positioning ring in a generally arcuate path, and having a cutting element positioned therein and structured to oscillate laterally to facilitate smooth and effective cutting of the cornea. The cutting head assembly is structured to be detachably coupled to the positioning ring by a coupling member which permits movement of the cutting head assembly relative to the positioning ring along the generally arcuate path, but maintains sufficient engagement therebetween to ensure that smooth, steady, driven movement is maintained <IMAGE>

IPC: H01F27/42
Filed: 1986-05-21
Abstract: The invention relates to a method and to an arrangement for controlling the respective conduction times of two directionally opposed electrical devices (9, 10) which are mutually connected in parallel and permit current to pass therethrough solely in one direction, and which also permit current (l<sub>2</sub>) to pass through the primary winding (2) of a transformer during a respective half-period of an A.C. voltage (U,) applied to the primary winding, this control being effected so that the magnetizing current through the transformer can be advantageously minimized and/or held beneath a given limit value when an asymmetric load (4, 5) is applied to the secondary side (3) of the transformer. A magnetizing current in the primary winding corresponding to the load (5) of the secondary winding (3) is controlled through the agency of different conduction times of the two directionally opposed devices (9, 10).

Abstract: A pilot operated pressure valve (40) which limits the rate of pressure rise and substantially eliminates excessive system pressure spikes, the valve including an inlet (42), a hollow cylindrical main body (44) sealingly connected at one end thereof to the inlet (42), a pilot chamber (46) having a sleeve slidably mounted within the main body (44) and an operating pressure adjustment (48) connected to another end of the main body (44) adjacent another end of the pilot chamber (46) for varying the operating pressure of the valve. A main chamber (30) receives pressurised fluid metered through a main orifice (18) and discharges pressurised fluid through a damping orifice (22) when the main chamber is filled and fluid inlet pressure exceeds a preselected inlet pressure level sufficient to open a spring biased pilot ball (15) downstream of the damping orifice (22). The inlet (1) will open an exit port (2) upstream of the main orifice (18) for discharging pressurised fluid from the valve back to a supply tank when inlet pressure exceeds the operating pressure. Pressurised fluid is also metered from the pilot chamber (44) through a control orifice (7) into a loading chamber (32) to automatically further vary the operating pressure of the valve by including a relief valve for discharging pressurised fluid from said pilot chamber when fluid pressure exceeds the operating pressure.

Abstract: A method of making a MOS field effect transistor having shallow source and drain regions with improved breakdown and leakage characteristics includes the step of forming a layer of a metal silicide along a surface of a body of silicon at each side of a gate which is on an insulated from the surface. A high concentration of an impurity of a desired conductivity type is implanted only into the metal silicide layers. A lower concentration of the impurity is then implanted through the metal silicide layers and into the body just beneath the metal silicide layers. The body is then annealed at a temperature which drives the impurities from the metal silicide layer into the body to form the junctions. <IMAGE>
