Abstract: HYPERMEDIA ARRANGEMENT USING A WINDOW      SYSTEM AND LAYERED INTRINSICS Abstract An information management system having a hypermedia file that works with the X Window System and Xt Intrinsics is disclosed. The disclosed arrangement generates and uses a hypermedia information management system, which includes a windowing system and, responsive to a set of intrinsics, generates a set of widgets. A hypermedia file, which includes a hierarchical ordering of objects, such as hypermedia lines and hypermedia segments among the hypermedia lines, is generated. A specially encoded function with parameters for defining items sends a file to be included in a window, the location and size of the window in a display of the file, and a label for identifying the generated segment is used for controlling the display of information, whether pictorial, graphic, text, et cetera, or the execution of another program from the hypermedia file. A specially encoded function is also used for notifying a user of information from the hyperfile, the information being correlated to the particular detected one of the specially encoded functions.

IPC: A61J1/14
Filed: 1992-02-18
Abstract: Abstract Dispenser A dispenser for dispensing sterile solution which includes a valve means to control the dispensing of the sterile solution from a container.  The valve means comprises a solution outlet means, and an air inlet opening having associated therewith a filter membrane to filter the air passing into the container.  When dispensing solution force is applied to the container in order to achieve this, and this force causes the solution outlet means to open and prevents access of the solution to the air inlet opening.  Now when the force is relieved a partial vacuum is formed in the container which causes the solution outlet means to close and air is drawn into the container via the air inlet opening and through the filter membrane.

Title: Positive feedback error diffusion signal processing
Inventor: EDGAR ALBERT D
IPC: H04N1/405
Filed: 1992-03-24
Abstract: A  method  for  processing   signals   to  diffuse quantization  error  spatially  or  temporally.   Positive feedback of the quantization error is used to reduce the relative noise for the low frequencies of the spectrum. According   to   a   preferred   implementation   in   a two-dimensional  spatial  application  involving  a  base pixel and three adjacent orthogonally arranged pixels, error  attributable  to  quantization  at  the base  pixel location  is  provided  as  positive  feedback  for  the quantization of the diagonally adjacent pixel. Offsetting and complementary values of the quantization error are also diffused to the remaining two diagonally positioned pixels.  The composite of the four pixels forms a square with a zero net error diffusion along the horizontal, vertical and diagonal orientations.

Abstract: Disclosed is a multi-point welding method capable of certainly welding an object having a number of points to be welded for a short time.  First, an approximately cylindrical base body is formed by alternately laminating a flat sheet and a corrugated sheet and then winding them in a spiral shape.  In this case, there exist a number of contact points of the flat sheet to the corrugated sheet, that is, points to be welded.          Next, there is provided an electrode apart from one end surface of the base body by a specified interval and facing to the end surface.  After that, by intermittently applying a current across the electrode and the one end surface of the base body thereby intermittently generating electric discharges between the electrode and the one end surface of the base body, to thus fuse and weld the points to be welded of the flat sheet to the corrugated sheet.  With this arrangement, it is possible to certainly weld multi-points to be welded for a short time by only intermittently applying electric discharges.
