[Class 37] Measurements of high-frequency power by the difference of the squares of the sum and differences of two quantities derived from the currents and voltage circuits are effected by a current transformer secondary winding connected to two series-connected thermal, diode, or dry-surface rectifying or conversion circuits producing the current quantity, and a resistor connected on the transformer and rectifier circuit for producing the voltage components.

A method includes generating an electrical signal representing a magnetic field using a magnetic field sensor having alternating layers of magneto-strictive material and piezo-electric material. The method also includes performing up-conversion or down-conversion so that the electrical signal representing the magnetic field has a higher or lower frequency than a frequency of the magnetic field. The up-conversion or down-conversion is performed before the magnetic field is converted into the electrical signal. The up-conversion or down-conversion could be performed by repeatedly sensitizing and desensitizing the magnetic field sensor. This could be done using a permanent magnet and an electromagnet, an electromagnet without a permanent magnet, or a movable permanent magnet. The up-conversion or down-conversion could also be performed by chopping the magnetic field. The chopping could involve intermittently shielding the magnetic field sensor from the magnetic field or moving the magnetic field sensor with respect to the magnetic field.

PROBLEM TO BE SOLVED: To carry out the production or modification of a polymeric product under accurately controlled conditions until a desired degree of conversion or modification attains according to an infrared-attenuated total reflection(IR-ATR) spectroscopic method by a specific method. SOLUTION: In the case of a polymeric reaction, the absorbance of IR absorption bands respectively characteristic of monomers used and that of a polymeric product are measured. In the case of the polymeric modification, the IR absorption bands respectively characteristic of the starting material and the modified polymer are measured. In the process, the IR-ATR measurement is directly carried out in a short period under conditions so that the viscosity of the contents of a stirred reactional vessel is 10,000 Pas at the maximum and the flow velocity is 0.01-10 m/s measured at a position of an immersion probe by using the immersion probe in the stirred reactional vessel. The degree of conversion or modification is calculated from the resultant measured values according to formulae I and II [M(t) is the degree of modification; U(t) is the degree of conversion; A(t0 ) and A(t) are each the absorbance of the absorption bands of the monomer or starting material at the time of initiating the reaction and the time t] to terminate the reaction when a desired degree of conversion or modification is attained.

794,896. Semi-conductor devices. STANDARD TELEPHONES & CABLES, Ltd. June 3, 1955, No. 15975/55. Class 37. A point contact semi-conductor device is electroformed by passing current through the contact, while the semi-conductor crystal is maintained at a temperature sufficiently high to ensure that its conductivity is intrinsic. In Fig. 1, the crystal 1 of N-type Ge or Si is placed in an oven 4 heated by element 5, and current pulses from a charged capacitor 9 are applied through point contact 3. Alternatively, the electroforming current may be applied from a constant voltage, or a constant current source. In the case of germanium, the temperature necessary to ensure that the conductivity is intrinsic (i.e. that the thermally generated carriers are sufficiently numerous to render insignificant the carriers due to lattice imperfections) lies between 150‹ and 300‹ C. The process facilitates control of electroforming by eliminating uncertainties due to variations in the electrical properties of the semi-conductor material. Specifications 747,198 and 794,895 are referred to.

A real-time ammonia leak detection and processing method for a small ammonia refrigeration diffusion-absorption refrigerating apparatus dedicated to a refrigerator or a wine cabinet or a refrigerated container, comprising a container body, wherein the rear part of the container body is provided with a small ammonia refrigeration diffusion-absorption refrigerating apparatus, and at least one highly sensitive ammonia sensor is installed in the refrigerating apparatus. In the method, after the ammonia gas concentration is detected and data collection processing is performed at the same time, various countermeasures are used to prevent the loss caused by an ammonia gas leak; and the determination is accurate and rapid. The accuracy is up to 0.01 PPM. The concentration at the time that the standard is exceeded can be accurately determined, and the determination result is easy to display, thus improving visualization. During the detection of the ammonia concentration, according to the accuracy requirements, the concentration of the ammonia gas that needs to be detected and controlled and a processing method are set, and the number of ammonia detectors is arbitrarily set, wherein this is suitable for large-scale application. At the same time, miscalculations by a single ammonia concentration detection apparatus are also avoided. La présente invention concerne un procédé de détection et de traitement des fuites d'ammoniac en temps réel destiné à un petit appareil de réfrigération par diffusion-absorption par réfrigération d'ammoniac dédié à un réfrigérateur ou une armoire à vin ou à un récipient réfrigéré, comprenant un corps de récipient, la partie arrière du corps de récipient étant munie d'un petit appareil de réfrigération par diffusion-absorption par réfrigération d'ammoniac, et au moins un capteur d'ammoniac fortement sensible étant installé dans l'appareil de réfrigération. Selon le procédé, une fois que la concentration en gaz ammoniac est détectée et que le traitement de collecte de données est exécuté en même temps, diverses contre-mesures sont utilisées pour empêcher la perte provoquée par une fuite de gaz ammoniac ; et la détermination est précise et rapide. La précision atteint 0,01 PPM. La concentration au moment où la norme est dépassée peut être déterminée avec précision, et le résultat de détermination est facile à afficher, améliorant ainsi la visualisation. Durant la détection de la concentration d'ammoniac, en fonction des exigences de précision, la concentration du gaz ammoniac qui doit être détectée et contrôlée et un procédé de traitement sont définis, et le nombre de détecteurs d'ammoniac est défini arbitrairement, ce qui est approprié à une application à grande échelle. D'autre part, les erreurs de calcul commises par un appareil unique de détection de concentration d'ammoniac sont également évitées. 一种冰箱或酒柜或冷藏箱专用的小型氨制冷扩散吸收式制冷装置氨泄漏实时检测处理方法，包括容器主体，容器主体后部设置有小型氨制冷扩散吸收式制冷装置，在制冷装置内安装有至少一个高灵敏度氨气传感器，氨气传感器连接控制板，该方法同时对氨气浓度进行检测并经数据采集处理后，启动各种应对手段，防止氨气泄漏造成损失；判断准确、快速。精确性达到0.01PPM。能够准确判断超标时的浓度，判断结果易于进行显示，提高可视化；在检测氨气浓度时，可根据准确性要求，设置需要检测、控制的氨气浓度以及处理方式，并且任意设置氨气探测器的数量，适合大规模应用；同时又避免单一的氨气浓度检测装置的误判。
