Abstract: Cette invention concerne un panneau d'écriture pour tableaux électroniques et analogues qui permet d'éviter d'effacer le tableau à la main lorsque ce qui a été écrit sur ledit tableau doit être totalement effacé. On écrit à l'aide d'un instrument d'écriture (14) sur une surface d'une partie frontale étirée d'un support d'enregistrement (12) sans fin, prévu dans le tableau (10) d'écriture. L'instrument d'écriture utilisé fait usage d'une encre que l'on peut facilement effacer avec un liquide détergent (37). Sur une face arrière d'une partie étirée du support d'enregistrement (12), on dispose d'un organe de nettoyage (26) qui fait face à une surface externe du support. Lorsque l'on souhaite effacer tout ce qui a été écrit, on actionne un déclencheur d'effacement (20a) pour déplacer le support d'enregistrement (12) et actionner une pompe (34). Conformément à l'invention, on fait circuler le liquide détergent (37) contenu dans un réservoir (32) à travers l'organe de nettoyage (26) par l'intermédiaire de tubes (30), (33) qui doivent être attachés, à travers une ouverture (26b) de l'organe de nettoyage (26), à une surface du support d'enregistrement (12) que l'on déplace.

Granted: 2000-11-07
Abstract: A speech signal input from a microphone is distributed by a distribution amplifier.  Using output signals of a filter group of cos phase having cut-off frequency moderate on low frequency side and steep on high frequency side and of similar filter group of sin phase, stability index is calculated based on magnitude of amplitude modulation and magnitude of frequency modulation of the signals, by stability index calculating portion and fundamental frequency extracting portion.  Based on the result of calculation, approximate value of fundamental frequency is calculated based on an output of a channel indicating maximum stability, and based on the approximate value of fundamental frequency, instantaneous frequency extracting portion extracts precise instantaneous frequency as fundamental frequency, interpolating value of instantaneous frequency from adjacent frequency channels.

Abstract: A method is provided for recovering nickel from high magnesium-containing lateritic ores which also contain iron. The ores which are referred to as saprolitic ores are subjected to leaching (2) with a mineral acid from the group consisting of HC1, H2SO4 and HNO3, HC1 being preferred. Following leaching with HC1, for example, the pregnant solution obtained is separated from undissolved solids and the nickel preferably recovered by contacting the solution with a resin (4) selective to nickel absorption. The raffinate remaining which contains iron and magnesium chlorides may be subjected to pyro-hydrolysis (10A) to produce their respective oxides and free HC1 for recycle into the leaching system. The nickel is extracted from the resin using a stripping solution of the acid, and the nickel thereafter extracted from the nickel-loaded stripping solution.

Abstract: An optical power divider using a beam separator and a beam expander, and a fabrication method therefor. The optical power divider includes an input optical waveguide having an input port for receiving incident light, for guiding the light incident via the input port, a plurality of output optical waveguides having at least two output ports, for outputting the light incident via the input optical waveguide to the output ports, wherein the number of output optical waveguides is equal to that of the output ports, and a beam separator located at a branch area in which the light incident on the input optical waveguide diverges toward the output opticalwaveguides, the beam separator being made of a material having a refractive index lower than the core of the input and output optical waveguides, for separating the light to the output optical waveguides with a predetermined ratio. Therefore, the length of the optical power divider becomes short and insertion loss can be lowered. Also, an optical power divider for the specific use, providing different splitting ratios between inner and outer output ports, can be easily designed by controlling the lengths of a side of each beam separator and beam expanders, and the splitting ratio of the output optical power of the optical power divider can be controlled. Also, the cost of fabricating the optical power divider can be reduced.

Granted: 2006-12-19
Abstract: Discloses a blocking time maintenance circuit that is applied to a resonant-transition zero voltage switching (ZVS) power converter having saturable core reactors to induce a current in the primary of the transformer which enables ZVS. The circuit includes a peak detector for producing a signal having a magnitude proportional to an input voltage. A biasing mechanism, comprising a current source, is provided in order to reset the saturable core reactors in a controlled manner. A control mechanism is connected to the peak detector and the current source in order to generate a reset current, the magnitude of which is correlated to the input voltage. In this manner, the volt-time product of the saturable reactors is varied, thereby maintaining the blocking time relatively constant over a wide range of input voltages and ensuring that the output voltage does not fall out of regulation.

Abstract: Methods and apparatus for providing a security check are disclosed. Many conventional security checks require the recording or transmission of a user data sets associated with respective authorised users . A problem arises with these systems if the user data set becomes known by unauthorised persons. In order to address this problem the present invention proposes the recording or transmission of only part of the user data set in insecure sections of the system. For example, a security check preventing unauthorised remote access to a shared computer (20) is provided by capturing a user data set representing a user's iris, operating the user's personal computer (10) to select only a portion of the captured data set requested by the shared computer (20) and transmitting the portion along a telecommunications line (16). The shared computer (20) derives partial data sets from stored user data set s using a similar selection to that used by personal computer (10) and compares the partial data set it has derived with the partial data set transmitted by the personal computer (10) in deciding whether to grant access. Point-of-sale devices and cards recording only partial user data sets are also disclosed.

Abstract: The present invention generally relates to an elastic ski covering having removable fasteners. In a preferred embodiment, The ski covering is made from a stretchable, washable, water-permeable, elastic material and is formed into an elongated tube, similar in configuration to a sock. A pair of skis, arranged bottom- to-bottom are inserted into the ski covering, which stretches to fit snuggly over the skis and their associated bindings. The length of the ski covering, in conjunction with its elastic nature, allow the ski covering to completely cover skis having a widely varying length. The open end of the ski covering includes integral straps for tying the end closed after the skis have been placed therein. A pair of removable fasteners are provided and are placed on either side of the ski bindings in order to securely affix the ski covering to the skis and to securely hold the skis against one another. The removable nature of these fasteners allows them to be placed next to the ski bindings, regardless of how far apart the binding components are fitted on the particular skis being covered.
