Title: Method and apparatus for processing a tubular container
Inventor: IMAIZUMI YASUYUKI
IPC: B29C35/04
Filed: 1997-04-24
Granted: 2005-06-28
Abstract: There is provided a method and apparatus for processing a thinly walled tube of thermoplastic resin to produce a tubular container having an inwardly directed flange section in a hole formed at an end of the thinly walled tube. In the first step, the thinly walled tube is secured to a tube holder provided with a male mold for molding the flange section in the hole and forming an opening located inside the flange section. The front end of the thinly walled tube projects by a predetermined distance from the front end of the tube holder. Then, in the second step, hot air is blown to an inner wall surface of the thinly walled tube at and near the front end thereof and the outer wall surface of the thinly walled tube is cooled also at and the front end thereof, to produce a temperature difference between an inside and an outside of the thinly walled tube, so as to deform the front end of the thinly walled tube into a flange projecting radially. When the inner wall surface is heated to a temperature lower than a melting point of the inner layer, the front end of the thinly walled tube is deformed inwardly. When the inner wall surface is heated to a temperature higher than the melting point of the inner layer, the front end of the thinly walled tube is deformed outwardly. Finally, in the third step, the deformed front end of the thinly walled tube is molded into the flange section showing a predetermined shape and forming the opening located inside the flange section by means of a female mold cooperating with said male mold.

Abstract: An optical filter is provided having first and second graded index (GRIN) lensespreferably disposed in a coaxial relationship so that they have a common optical axis. Each of the GRIN lenses have an endface providing a port at predetermined location. The ports are disposed on opposite sides of the optical axis and each of the ports are substantially equidistant from the optical axis, so as to be oppositely offset from the optical axis by a same amount. The filter also includes an optical interference filter disposed between other endfaces of the first and second graded index lenses. By changing the location of the ports by a same small amount, the center wavelength of the filter changes by a small amount, thus in manufacture, the filter is tunable. After tuning the filter to a desired wavelength, the locations of the ports are fixed.

Abstract: An improved earth-working tool including a disc having a central portion and an outer peripheral portion. The disc is rotatable about a substantially horizontal axis extending through the central portion. A peripheral portion has a plurality of first points along the outer peripheral portion which are closer to the axis than other points on the outer peripheral portion. The first points are substantially equidistantly spaced from the axis. Radially inner sections of the outer peripheral portion are disposed along a line which is substantially tangential to an arc formed around the axis of rotation and through the first points, whereby the substantially tangential sections will tend to cut residue on top of the soil in a more downward direction than conventional circular discs do. The discs also have radially outer sections on the outer peripheral portion which are not along the substantially tangential lines and which are further from the axis than the first points. An alternate embodiment has an outer periphery with alternating radially inward and radially outward arcuate sections, the inward arcuate sections being longer than the outer sections.

Abstract: Improved apparatus and method for mixing and introducing gas into a large bo dy of liquid. The apparatus supports and rotates a plurality of spoke-like discharge members (484) below the surface of the liquid. The members have upwardly facing perforated discharge surfaces (485) through which compressed gas is released up into the liquid. Preferably the members have non-porous lower portions. To counter upward 'lift pump" effect forces created by the rotating members, th e members are tilted with their leading edges lower than their trailing edges. The tilt of the members and the speed of rotation are balanc ed so that the resultant angle of attack of the liquid relative to the discharge surfaces is zero or slightly greater, for efficiently and effectively shearing the emerging gas into relatively small size bubbles.</S DOAB>

Title: Handover control method and apparatus using fuzzy logic
Inventor: HOCH JAMES EDWARD
IPC: G05B13/02
Filed: 1998-12-23
Granted: 2003-06-24
Abstract: A method and an apparatus for using fuzzy logic to determine when handovers are desirable and the extent to which the radio transmission power in a cellular telephone network should be adjusted. The mobile phone and the base transceiver station measure certain system parameters, including rate of handover, quality, distance, level, call duration, and power. These measurements are input to a fuzzifier. The fuzzifier applies standard fuzzy-set-theory membership functions to the measurements, and the fuzzifier outputs a set of fuzzy variables corresponding to the measurements. The fuzzifier outputs are input to an inference engine. The inference engine contains a set of rules that, when applied to the inference engine inputs, indicate: when a handover should be performed; when a handover should not be performed; and the amount by which, if any, the transmission power should be adjusted.
