Title: Magnetic sensor, and method of compensating temperature-dependent characteristic of magnetic sensor
Inventor: SATO HIDEKI
IPC: G01R33/09
Filed: 2002-11-29
Granted: 2010-09-14
Abstract: A magnetic sensor 10 includes GMR elements 11-18, and heating coils 21-24 serving as heat generating elements. The elements 11-14 and 15-18 are bridge-interconnected to constitute X-axis and Y-axis sensors, respectively. The heating coils 21, 22, 23, and 24 are disposed adjacent to the elements 11 and 12, the elements 13 and 14, the elements 15 and 16, and the elements 17 and 18, respectively. The heating coils 21-24, when electrically energized, heat mainly the adjacent elements. Therefore, the elements can be heated and cooled in a short period of time in which constant geomagnetism can be ensured. Data for compensation of temperature-dependent characteristic (ratio of change in sensor output value to variation in element temperature) is obtained on the basis of the temperatures of the elements before and after the heating, and the magnetic sensor outputs. before and after the heating. Subsequently, the temperature characteristics of the elements are compensated on the basis of the data.

Abstract: The invention relates to a structure for the construction of folding and unfolding buildings, for example, horse stables but not limited thereto, of the type comprising frames made from welded profiles and covered with panels or sheets which may comprise doors, windows or ventilators, the whole assembly being covered by a roof. The structure is characterised in comprising, after deployment and installation, a parallelepiped volume with a rigid front façade (2) and rear façade (3) and two folding lateral walls. Each lateral wall (4, 5) comprises jointing means (19) on one central vertical joint axis (6) and on two secondary vertical joint axes (7 and 8) provided to either side of the central axis (6). Each lateral wall is thus composed of four rectangular leaves (20) of the same height and which can be folded by means of an accordion style of folding, characterised in that the distance between the two central axes (6) remains constant and that the structure comprises two fixing or anchoring means (12 and 13) on each lateral wall (4, 5), positioned on top of the structure and symmetrically with relation to the central axis (6). The method for folding or unfolding is characterised in that a lifting beam is used to raise the structure which folds or unfolds under the influence of the weight thereof, due to the force exerted by the weight on cables (27, 28) fixed between the lifting beam and the structure.

Abstract: An exhaust gas recirculation control device in a diesel engine, capable of suppressing NOx and smoke discharged. A first temperature sensor (11) is provided at a portion more on the upstream side than a portion where a suction air path (3) joins an exhaust gas recirculation path (4), and a second temperature sensor (12) is provided on the downstream side.  Further, an engine load detection sensor (6) and an engine speed detection sensor (7) are arranged. The exhaust gas recirculation control device also has memory means where the temperature of suction air before it is mixed with an exhaust gas and a temperature value at a second temperature sensor installation position are previously memorized, the temperature value corresponding to an appropriate exhaust gas recirculation amount that is uniquely defined by an engine load and an engine speed. Further, judging means is provided. The judging means compares the corresponding temperature value memorized in the memory means and a value detected by the second temperature sensor. When the detected value is within a predetermined range relative to the temperature value, a circulation exhaust gas amount is determined to be appropriate, and when the detected value is not within a predetermined range relative to the temperature value, a circulation exhaust gas amount is determined to be abnormal.

Abstract: The present invention relates to a novel integrated process for the recovery of sulphate of potash (SOP) from sulphate rich bittern. The process requires only bittern and lime as raw materials. Kainite type mixed salt is obtained by fractional crystallization of the bittern. Kainite is converted into schoenite with simultaneous removal of NaCI in a single step and the filtrate (SEL) is used for production of KCI. The schoenite is reacted with aqueous KCl to yield SOP and the filtrate (KEL) is recycled in the kainite to schoenite conversion step. The production of KCl from SEL is carried out with the aid of DPA. Lime is treated with DPA in water for the production of highly soluble Ca(DPA)2, which in turn treated with SEL to produce insoluble K(DPA) with >95% yield. The isolated K(DPA) is treated with 1:1 HCl to produce KCl and insoluble DPA, which can be recycled for the production of Ca(DPA)2. The aqueous KCl thus obtained is treated with schoenite to prepare SOP, purity 90-92%. The KEL obtained along with SOP is recycled to generate schoenite. Utilisation of all effluent and intermediate streams allow for an overall SOP yield >89% w.r.t. the potash content in the mixed salt.

Title: Production and purification of esters of conjugated linoleic acids
Inventor: RONGIONE JOSEPH C
IPC: C11C3/10
Filed: 2003-12-23
Granted: 2011-12-06
Abstract: A process to refine esters of conjugated linoleic acids via distillation in a single or multi-pass distillation operation is provided. Thermal rearrangement of conjugated linoleic acid components during distillation is prevented or reduced by the use of a low residence time and/or reduced pressure distillation apparatus. A process to produce refined esters of conjugated linoleic acids is also provided. The process transesterifies a linoleic acid-containing oil to generate an alkyl ester composition which further undergoes isomerization at a temperatures typically between about 90-140 ~C to form an ester stream containing conjugated linoleic acid esters, which is then distilled to obtain the refined esters of conjugated linoleic acids. The transesterification and isomerization steps can be performed in one reaction vessel without an intervening distillation step. The transesterification and isomerization steps can occur concurrently in a continuous reaction system using a dual reaction zone apparatus. Refined ester compositions produced by the processes and enriched in desirable conjugated linoleic acid isomers are also contemplated.
