Inventor: TOYOMAKI KAZUYA
IPC: H03K17/16
Filed: 1981-03-27
Abstract: A switching circuit for effecting selection from a plurality of input analog signals comprises a voltage amplifier (Av) selectively responsive to one of the input analog signals, a plurality of series circuits of two resistors (Ral, Rbl; Ra2, Rb2) each of which series circuits is interposed between each of the inputtermina(s (IN1, IN2) and an outputterminal (OUT) of the voltage amplifier (Av) and a plurality of semiconductor switching elements (S1, S2) respectively interposed between junctions connecting the two resistors (Ral, Rb resp. Ra2, Rb2) of respective series circuits and an inverting input terminal of the voltage amplifier (Av) while a noninverting input terminal of the same is grounded. With this arrangement, only a negligibly small amount of current flows via each of the switching element (S1, S2) in on-state thereof so that distortion due to the variation in on-state resistance of the switching element (S1, S2) can be ignored, while switching noise is suppressed because the switching elements are used at an imaginal short point of the voltage amplifier (Av). Auxiliary switching elements may be provided for preventing crosstalk between different channel signals.

Abstract: An oven for cooking and/or defrosting food by recirculating heated air is provided with a temperature control means for measuring the actual internal temperature of the food and switching the oven off when the desired temperature is reached. The control includes a temperature sensing device which is insertable into the food for monitoring the actual internal food temperature and a circuit for monitoring the malfunctioning of the sensing device. The monitoring circuit is incorporated into the temperature control and is capable of switching the oven off when a malfunction is detected. The control circuit is also provided with a bypass circuit to allow the oven to be operated without the temperature sensing means.

Abstract: A device for detecting concentrations of oxygen in gases by using an oxygen sensor element (10) having a substrate (12) provided with a heater (14; R H ) and a concentration cell part in the form of a laminate including a solid electrolyte layer (20; R s ) supported on the substrate. The device has a power supply circuit (50, R,-R,) to apply a controlled voltage (V H ) to the heater (14) to keep it at a constant temperature by controlling its resistance (R H ) to a constant value, and a current supply circuit (56,R 4 -R 7 ) which forces a controlled DC current (I c ) to flow through the solid electrolyte layer (R s ) in the sensor element (10) to thereby maintain a reference oxygen partial pressure in the sensor element. The current supply circuit (56,R 4 -R 7 ) is electrically associated with the power supply circuit (50,R,-R,) so as to vary the intensity of the current (I c ) in inverse proportion to the voltage (V H ) applied to the heater (R H ) for the purpose of maintaining the reference oxygen partial pressure constant even when the temperature of the concentration cell part of the sensor element (10) varies depending on the temperature of the gas subject to measurement.

Après que les anticorps de classe IgE présents dans un échantillon de liquide ont réagi avec les allergènes déposés sur les filaments (12), ils sont détectés avec les deuxièmes anticorps marqués avec des traceurs radioactifs, fluorescents ou enzymatiques. En utilisant un traceur radioactif à énergie élevée, tel que le I125, des techniques auto-radiographiques à amélioration de l'écran à phosphore permettent une analyse diagnostique au moyen de densitomètres ou même à l'oeil nu.

Abstract: In a gear mounting having a spindle (16) extending generally normal to a carrier, the spindle (16) is cantilevered back from the outer end of a tie-bolt (14) and is permitted limited axial excursions to adapt itself to the tooth loading. tt is particularly suited to mounting planets in an epicyclic gear. 
     The outer end of the spindle (16) is clamped between the head of the tie-bolt (14) and a tubular compression member (15) of lesser axial extent than the spindle (16), and between that member and the carrier there is a bush (17), also in the compression chain. The tubular member (15) is more flexible than the bush (17) and the bolt (14) can also flex to allow the axial excursions. The tubular member (15) may be integral with the bush (17) or separate from it, but in either case the geometry of the various components can be such that easy tolerances are permissible to facilitate assembly. However, when the tie-bolt (14) is tensioned distortions occur to close radial clearances and centralise the components. 
     An application of this mounting is to an epicyclic gear in which there are double planets whose parts are of different pitch to give an added reduction.

Abstract: The present invention relates to mixtures of sulfonated thermoplastic polymers and amine-treated clays which function as viscosification agents when added to oil-based drilling muds which are the fluids used to maintain pressure, cool drill bits and lift cuttings from the holes in the drilling operation for oil and gas wells. The sulfonated thermoplastic polymers have 5 to 100 meq. of sulfonate groups per 100 grams of the sulfonated thermoplastic polymer, wherein the sulfonated groups may be neutralized with a metallic cation or an amine or ammonium counterion. A polar cosolvent can optionally be added to the mixture of oil drilling mud and sulfonate thermoplastic polymer, wherein the polar cosolvent increases the solubility of the sulfonated thermoplastic polymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sulfonated polymer.

Abstract: Un réseau local comprend une pluralité de terminaux informatiques (1), chacun connecté à un canal informatique commun (2) par l'intermédiaire d'un récepteur (5), d'un émetteur (6) et d'un coupleur directionnel (7). Afin de résoudre des conflits entre différentes sollicitations du canal, et en même temps de donner à chaque terminal une chance statistiquement égale d'obtenir accès au canal, chaque terminal sollicite accès au canal en transmettant, quand le canal est libre, des signaux de demande de transmission dans une séquence de périodes de temps consécutives, le terminal transmettant une demande ou ne transmettant pas de demande pendant chaque période de temps selon un code prédéterminé. Si pendant une période de temps quelconque un terminal informatique (1) transmet une demande mais ne détecte aucune demande transmise par d'autres terminaux, le terminal reçoit l'autorisation d'utiliser le canal (2). Si le terminal (1) ne transmet pas pendant une période de temps quelconque et un autre terminal transmet une requête, alors le terminal abandonne la sollicitation.
