Title: Reader with a/d conversion and high precise and high speed modes
Inventor: NAGANO FUMIKAZU
IPC: H04N1/028
Filed: 1994-02-15
Abstract: Each of even series outputs of a CCD is clamped by a third capacitor and a fifth transistor in a high precise mode of a reader. Each of odd series outputs of the CCD is clamped by a first capacitor and a second transistor. The clamped odd and even series outputs are converted to digital signals by a first AD converter. In a high speed mode of the reader, odd series outputs of the CCD are clamped in a unit of one line period by first and second capacitors and the second transistor. In the high speed mode, even series outputs of the CCD are clamped in the unit of one line period by third and fourth capacitors and a fifth transistor. The clamped odd and even series outputs are respectively converted to digital signals by individual first and second AD converters. In this reader, the high precise mode or the high speed mode can be selected in accordance with necessity.

Title: Internal bait weight apparatus
Inventor: BRICKEY JEFFREY L
IPC: A01K83/06
Filed: 1994-03-01
Abstract: INTERNAL BAIT WEIGHT APPARATUS           ABSTRACT OF THE DISCLOSURE         A line fishing apparatus having a generally bulbous head and tapered tail is inserted inside a fish used for bait. Before the apparatus is inserted, the apparatus slides freely along the fishing line.  The bulbous head portion is shaped to fit the inner dimensions of the bait's mouth.  When the bait's mouth is closed around the apparatus, a bumper portion sticks out from the mouth protecting the head of the fish from striking bottom.  As the apparatus is inserted, the tail portion is pushed through the bait's stomach toward the bait's tail.  The apparatus tail portion is curved along an arc as it tapers to a distal end.  The curvature forces the bait to curve along its length.  As a result, when the line is pulled through the water, a swinging or spinning action is induced.  The swimming motion generally resembles that of a live, injured fish.  The apparatus tail portion is generally rigid to maintain its curvature, yet malleable enough for a fisherman to bend so as to change the curvature, and thus, the swimming action.          A channel is formed through the bulbous head for receiving fishing line and hooks.  One end of the channel is tear-shaped, while the other end is key-hole shaped.  The line and hooks are inserted through the tear-shaped end and come out the key-hole.  The hooks then are set in the bait fish.  The key-hole is shaped so that pull on the line forces the hooks toward an area of the key-hole through which the eye of the hook can not fit.  The tear-shaped end closest to the pole, however, allows the line to play relative to the bait's mouth. As the line is pulled, a  ridge formed between the tear-shaped opening and the bumper protects the bait's lower jaw from being torn.
Patent CA-2118148-A1 (CA)
Inventor: APPEL WILLIAM D
IPC: H01P5/12
Filed: 1994-10-14
Abstract: Packaged signal routing circuits (e.g. on printed circuit cards or boards), route pulse signals with very short rise times from a lossy driver to multiple devices. In these routing circuits, a complex network of conductors branches from a common junction adjacent the driver output into multiple (in the disclosed embodiment, three) conduction paths of unequal length. In accordance with the invention, the internal impedance of the driver is matched to the aggregate charateristic impedance of the branch paths,  and a lossless compensating circuit is attached to a shortest branch path. The compensating circuit is designed to transfer signal reflections of predetermined form to the branching junction at the driver via the shortest branch. Without the compensating circuit, reflections presented to the branching junction from the shortest branch are dissimilar to reflections presented to that junction from other branch paths. Consequently, re-reflections return from the junction to the branches, causing distortions in signals sensed at the devices. However, with the compensating circuit connected in the shortest branch, reflections presented from that branch to the junction appear in a form matching  reflections  presented  by  the  other  branches;  and  the reflections from all branches then cancel  at the driver junction. Consequently, signals sensed at the devices have considerably reduced distortions due  to  the  absence  of  re-reflections.  In a preferred embodiment, the compensating circuit consists of a printed circuit trace of predetermined length (representing a transmission line stub with predetermined phase delay characteristics) in  series with a point capacitor (or several point capacitors) having predetermined capacitance (determining  the  shape  of  the  compensating  reflections).  The compensating circuit,  which extends beyond the end of the shortest branch, connects between the end of that branch and reference potential (e.g. ground). The end of the shortest branch is also attached to a device required to sense signals appearing at that point. A new method and polarized bridge device are disclosed for use in analyzing such networks in particular (and for analyzing transmission line effects in general).  This  method  and  device  permit  precise  observation  and comparison of reflections produced in branches of a network emanating from a common junction,  and accurate determination of compensation suitable for modifying such reflections.

Filed: 1993-06-23
Abstract: A process and apparatus are described for rapidly drying a wet, porous gel monolith of glass or ceramic, at subcritical tem-peratures without inducing any cracking of the gel. The wet gel is immersed in a liquid solvent in a chamber, and the liquid sol-vent is then heated and expelled from the chamber. Further heating, with or without the presence of a flowing inert gas, fully dries the wet gel. When an inert gas is used, the gas is delivered to the chamber with a controlled solvent partial vapor pressure, to correspondingly control the driving force for drying the gel.

Abstract: A membrane electrode and seal assembly (40) for an electrochemical fuel cell (10) comprises first and second layers of porous electrically conductive sheet material, such as carbon fiber paper (44, 50). The sheet material layers have a solid polymer ion exchange membrane (43) interposed therebetween. The sheet material layers cover and support the membrane (43) over substantially its entire surface area. The sheet material layers are coated with a catalyst (54) to render them electrochemically active, and are bonded together with the membrane to form a consolidated assembly. Openings (51, 52, 111, 112, 113, 114) are formed in the layers of sheet material and the membrane to accommodate the passage of fluids through the assembly. Channels (60, 61) formed in the layers of sheet material generally circumscribe the openings and the electrochemically active region of the sheet material. Solid preformed gaskets (62, 63) are disposed in the channels. The gasketing technique can also be applied to the membrane and seal assemblies (40) of the humidification portion (30) of fuel cell stacks (10).

Abstract: A magnetic transducer (100) for improving hearing in a hearing impaired person comprises a magnet assembly (12) and a coil (14) secured inside a housing (10) which is fixed to an ossicle of a middle ear (JJ). The coil (14) is more rigidly secured to the housing (10) than the magnet (12). The magnet assembly (12) and coil (14) are configured such that conducting alternating electrical current through the coil (14) causes magnetic fields of the coil (14) and magnet assembly (12) to cause the magnet assembly (12) and coil (14) to vibrate relative to one another. Because the coil (14) is mole rigidly secured to the housiog (10) than the magnet assembly (12), the vibrations of the coil (14) cause the housing (10) to vibrate. The vibrations are conducted to the oval window of the ear via the ossicles. In alternate embodiments, the transducer (100) is secured to ossicular protheses that are secured within the middle ear (JJ).
