Title: A method of corneal surgery by laser incising a contoured corneal flap
Inventor: JUHASZ TIBOR
IPC: A61F9/007
Filed: 2001-01-12
Abstract: In accordance with the present invention, a method for corneal laser surgery includes the step of first prescribing the size, shape and location of a lentoid of stromal tissue to be removed in order to correct the vision of a patient. Next, a contoured corneal flap having an interior surface and peripheral edge is created wherein the interior surface of the flap is shaped to conform to the prescribed anterior surface of the lentoid. To create the flap, the focal point of a pulsed laser beam is moved within the intrastromal tissue to photoalter a layer of tissue in the shape of the interior surface and the peripheral edge of the flap. Once created, the flap can be lifted to expose a bed of intrastromal tissue. Then, an excimer laser can be used to photoalter the bed of intrastromal tissue in a predetermined manner, thus creating a void in the shape of the prescribed lentoid. Finally, the flap can be repositioned over the lentoid shaped void and allowed to heal. The result is a reshaped cornea that effectively corrects a patient's  vision impairment.

Title: Radio transmission device and transmission directivity adjusting method
Inventor: HIRAMATSU KATSUHIKO
IPC: H04W16/28
Filed: 2000-03-29
Abstract: A reference signal is modulated in a modulation circuit 101. The modulated reference signal is multiplied by a transmission weight before being performed radio transmission processing at transmission RF circuits 109 to 111. Respective reference signals are combined at a combining circuit 119. Then, the combined reference signals are compared with original reference signal at a correction value control circuit 121. On the basis thereof, respective correction values of a phase and an amplitude are obtained. A radio transmission device adjusts the phase and the amplitude of transmission signal while employing the correction values.

IPC: E03D9/03
Filed: 1999-06-15
Abstract: A liquid dispenser (1) comprises a housing (2) and a hook (3) for suspending the housing (2) from the rim of a lavatory bowl.      A user inserts a sealed inverted reservoir bottle (6) into the housing (2), which breaks the seal. A porous pad (7) located in the housing (2) conveys liquid from the bottle (6) to a position within the stream of flushing water. The pad (7) can be adjusted to accommodate different lavatories and has two guide slots which are engaged by two fingers in the housing which define two extreme positions of the pad (7). To allow venting of the bottle (6), small vent holes (14) are formed in the pad (7). The pad may alternatively be a solid plate of the same shape but having a number of raised holes or elongate slots. The plate may have a venting post which mates with the mouth of the bottle (6). Venting may be achieved by providing an aperture in the bottle. The top of the bottle may be; provided with: a one-way valve; with a plug which seals the aperture, the housing having a pin which bears on the plug and releases it into the bottle; a breakable seal which covers the aperture, the housing being provided with a tube member which seals the aperture; or a removable tab which covers the aperture and which is broken away from the bottle prior to insertion, either by the user or, automatically, by a projection within the housing.

Abstract: Mucositis is treated and/or prevented by administrating to a patient a formulation comprising a tetracycline that is poorly absorbed from the gastro-intestinal tract. The tetracycline may be in the form of a pharmaceutically acceptable salt or a base.  The formulations may optionally also contain an antifungal agent to prevent fungal overgrowth due to reduction in the normal oral flora by the tetracycline.
