Patent CA-2266472-A1 (CA)
Inventor: ISHII YUKO
IPC: G01N1/38
Filed: 1997-09-02
Abstract: In an automatic sample examination and measurement instrument for use in conducting random measurement concerning a plurality of items, the measurement accuracy and measurement reproducibility are improved, and failure, which is ascribed to inclusion of bubbles, of an aliquoting apparatus is prevented.  Diluent is fed into sample-containing dilution vessels (11) by an aliquoting means so as to prepare diluted samples to be used for measurement. In order to remove small bubbles (13) produced during the preparation of such diluted samples, a predetermined quantity of diluted samples (12) are sucked from upper surfaces thereof by the aliquoting means, discharged into waste liquid cups, and discarded. The diluted samples (12) remaining in the dilution vessels (11) are used for measurement. Thus, the measurement accuracy and measurement reproducibility are improved, and failure, which is ascribed to inclusion of bubbles, of the aliquoting apparatus is prevented.

Patent CA-2267573-A1 (CA)
Inventor: IMAI HIROSHISA
IPC: A61B6/00
Filed: 1998-07-27
Abstract: L'invention concerne un thermomètre médical à rayonnement permettant de relever sans contact la température de la membrane du tympan, le thermomètre comprenant une section de réception de lumière (17) destinée à recevoir uniquement des rayons infrarouges provenant directement de la membrane du tympan et/ou de la zone située alentour; un dispositif de traitement de signaux (4) permettant de relever la température à la sortie de la section de réception de lumière, et un dispositif indicateur (18) destiné à indiquer la température relevée. Parce que le thermomètre n'est pas influencé par le rayonnement de chaleur provenant d'un autre point que la membrane du tympan et/ou la zone située alentour, la variation de température de la sonde (1) ne provoque pas d'erreurs de mesure et on peut donc relever la température précise. Vu à partir de la coupe transversale du thermomètre comprenant l'axe optique de l'élément capteur de lumière, l'élément de réception de lumière infrarouge est placé dans un triangle formé par trois lignes reliant trois points, et une intersection entre l'axe optique de l'élément capteur de lumière et un trajet optique où une ligne partant du bord de l'élément capteur de lumière de manière à être tangente à la paroi intérieure de la sonde du même côté que le bord de l'élément capteur de lumière par rapport à l'axe optique s'étend d'une extrémité imaginaire où la ligne coupe la surface d'extrémité de la sonde et passe par le bord de l'élément capteur de lumière du même côté que le point d'extrémité imaginaire par rapport à l'axe optique pour atteindre un point d'image du point d'extrémité imaginaire par l'élément capteur de lumière. Les deux points restants sont deux points d'image de l'élément capteur de lumière au point d'extrémité imaginaire.

Title: Method of constructing fully dense metal molds and parts
Inventor: TOBIN JAMES ROBERT
IPC: B23H1/04
Filed: 1998-02-09
Abstract: A method of constructing a fully dense metal part or a metal mold half for mating with another mold half to form a mold for casting multiple parts. Steps include placing a pattern having critical pattern surfaces in a flask having an open end. The critical pattern surfaces face upward. Other steps involve covering the critical pattern surfaces with a concentrated heat reversible gel solution added to the flask, and cooling the gel solution to form an elastic solid gel mold. Further steps include removing the flask and the pattern from the elastic gel mold, and casting a ceramic mold around the solid gel mold. In other steps the gel mold is liquified for removal from the ceramic mold and the ceramic mold is inverted so that its critical ceramic surfaces face upward. Still other steps involve covering the critical ceramic surfaces with a powder, and placing a quantity of an infiltration material over the powder, and placing the ceramic mold, the powder, and the infiltration material in a furnace at a temperature sufficient to melt the infiltration material without melting and sintering the powder. The quantity of the infiltration material is sufficient to fill voids between the particles, thereby generating a fully dense mold half.

Abstract: The invention relates to an apparatus for mechanically joining metal sheets, which lie flat one upon the other, by metal forming, having a tool set comprising at least one punch and one die which bounds a cavity in which the joining operation takes place, it being the case that at least one of these two tool parts can be driven via a driving force, produced by fluid supply, such that the punch displaces sheet-metal material out of a sheet-metal plane, and upsets it, under the action of deformation work, and the driveable tool part has a stop which is moved along with it and limits its penetration depth. For easy displacement limitation, it is provided that the stop is formed by a switching bolt which, upon reaching a selectable penetration depth, can be displaced against a switching linkage which can be brought into releasable latching engagement with a closing element of a valve which is arranged in the fluid supply and is intended for depth limitation, wherein the latching engagement is provided for maintaining a throughflow position of the valve, and the switching bolt is designed as a follower element, acting on the switching linkage, for disengaging the switching linkage from the closing element and switching the valve into a blocking position for the purpose of interrupting the fluid supply.

Filed: 1998-09-07
Abstract: The invention relates to a method for testing the authenticity of a data carrier (1) and/or an external device (2) which enters into data exchange with the data car-rier (1). According to the invention, the data carrier (1) and the external device (2) are each equipped with a special additional apparatus (4, 6) for generating and/or testing authenticity data. Data transmission between the data carrier (1) and the ex-ternal device (2) as required for authenticity testing is performed at least partly via a special transmission channel (B). The transmission channel (B) for transmitting authenticity data is separated physically or logically from a transmission channel (A) for transmitting standard data so that there is no mutual interference of data trans-mission via the two transmission channels (A, B). In authenticity testing, the addi-tional apparatuses for generating and/or testing authenticity data (4, 6) of the data carrier (1) and external device (2) and optionally also the transmission channel (B) for authenticity data must meet special demands which cannot be met by conven-tional designs. The transmission channel (B) for transmitting authenticity data is ac-tivable during the total time period between activation and deactivation of the data carrier (1) so that authenticity testing can be performed anytime.
