An intravascular device such as a catheter, having a flexible outer tubular portion or cannula and a relatively rigid inner tubular portion or stylet of metal such as stainless steel with a sharp pointed distal end protruding from the distal end of the cannula to pierce the skin and permit entry of the cannula into the vein of a patient. The opposite, or proximal, end of the cannula includes a tubular adapter or fitting to accept a corresponding tubular adapter at the proximal end of the stylet ...

A primary pan assembly adapted to be mounted to the motor of an air conditioning system which comprises a primary pan provided with a drainage hole on at least one side thereof and stud members extending from the bottom thereof, a support bracket disposed to support the primary pan, height-adjustable brackets operatively connected with said support bracket at opposite end portions thereof for varying the height of said height-adjustable brackets relative to each other, said height-adjustable bra...

An endoscopically guided novel naso-intestinal tube for intubation of the duodenum comprising a hollow flexible member, circumferentially mounted mercury bag and a series of drainage ports which is used in a novel intubation process to result in intubation of the duodenum without need of radiation and with minimal patient discomfort.

Apparatus and process for dilating the Sphincter of Oddi comprising a flexible cylindrical catheter with an expandible tip to allow verification of its location by outside palpitation and a plurality of hollow flexible dilators which are slidingly inserted coaxialy over the catheter to stretch the Sphincter to the desired extent, each dilater comprising an enlarged tip portion, a shaft portion and a tail or handle portion finned to accommodate the user.

A method for forming barrier ribs for a gas discharge display panel which includes the steps of: covering a glass substrate with a conductive ITO film; covering the conductive film with photoresist; exposing the photoresist to radiation; developing the photoresist so as to selectively remove portions of photoresist thereby creating apertures in the photoresist; etching the panel conductive ITO film so as to remove the conductive film in the apertures; depositing barrier rib material including gl...

Plastic primary pan assembly for use in air conditioning systems which includes a base primary pan containing a pair of blind plates having a pair of semi-cylinders, respectively, to be removed one of them from the base primary pan, a pair of rubber packings, and an assembly plate having a pair of semi-cylinders to be inserted into the base primary pan, after taking out one of the pair of blind plates from the base primary pan, assembling with a base primary pan instead of the blind plate so as ...

A method for fabricating a microactuator for an inkjet head, which achieves easy formation of oxide piezoelectric elements and upper electrodes having desired patterns, using a patterning process mainly used in the fabrication of semiconductor devices. The method includes the steps of sequentially laminating a vibrating plate, a lower electrode, an oxide piezoelectric sheet, and an electrode layer, patterning the electrode layer, thereby forming upper electrodes of a desired pattern, and pattern...
