摘要： PROBLEM TO BE SOLVED: To provide a fuel property sensor that prevents fuel gas from leaking to the outside and can be downsized.SOLUTION: A housing 10 of a fuel property sensor 1 includes a fuel chamber 15 into which fuel can flow. An outside electrode 51 is disposed inside the housing 10 and has an electrode chamber 55 communicating with the fuel chamber 15. An inside electrode 61 is disposed inside the outside electrode 51. A first glass seal 70 is disposed between the housing 10 and the outside electrode 51, and seals the fuel in the fuel chamber 15 by matching seal. A second glass seal 75 is disposed between the outside electrode 51 and inside electrode 61, and seals the fuel in the electrode chamber 55 by matching seal. Thus, fuel gas can be prevented from leaking to the outside. The load acting with thermal shrinkage is small in comparison with compression seal, so that the thicknesses of the housing 10, outside electrode 51, and inside electrode 61 can be decreased, and the whole sensor can be downsized.

摘要： PROBLEM TO BE SOLVED: To provide a substrate assembly which securely improves the connection strength between a mother substrate and a slave substrate and achieves small work hours in the manufacturing.SOLUTION: In a substrate assembly 60, since a part of a second through hole 75 is positioned outside a first through hole 73, when a mother substrate 66 is connected with a slave substrate 62 by solder S filling the first through hole 73, the solder S is easily supplied to the second through hole 75. Therefore, the second through hole 75 is unfailingly filled with the solder S. Further, after soldering, an operator can check if the second through hole 75 is filled with the solder S by visual inspection. Thus, the connection strength between the mother substrate 66 and the slave substrate 62 is unfailingly improved. Furthermore, the solder S supplied from the one surface side of the slave substrate 62 is easily flowed to the opposite side passing through the through hole 75. Hence, it is not necessary to perform the soldering from both surface sides of the slave substrate 62 and the manufacturing work hours is reduced.
摘要翻译：要解决的问题：提供一种可靠地提高母基板和从基板之间的连接强度并在制造中实现小的工作时间的基板组件。解决方案：在基板组件60中，由于第二通孔75的一部分位于第一通孔73的外侧时，当母基板66通过填充第一通孔73的焊锡S与从基板62连接时，焊料S容易地供给到第二通孔75.因此，第二通孔 75被焊料S充分填充。此外，在焊接之后，操作者可以通过目视检查来检查第二通孔75是否填充有焊料S. 因此，母基板66和从基板62之间的连接强度得到可靠的提高。此外，从从基板62的一个表面侧供给的焊料S容易流向穿过通孔75的相对侧。因此，不需要从从基板62的两个表面侧进行焊接，制造工作时间缩短。

摘要： PROBLEM TO BE SOLVED: To obtain a position detection sensor 1 with high detection accuracy even when electric signals output from a magnetic field formed from magnets 2, 3 as a movable element, and magnetic field detection means 4, 5 as a stator vary with temperatures. SOLUTION: The position detection sensor 1 has swelling portions 6, 7 swelling in an arc shape in a lateral direction, the two magnets 2, 3 displacing in a longitudinal direction, and the two magnetic field detection means 4, 5 that detect the magnetic field formed from the magnets 2, 3. Both of the magnets 2, 3 are polarized in the longitudinal direction, and one edge side forms an S pole, and the other side forms an N pole. Besides, the magnetic field detection means 4, 5 are disposed at a predetermined clearance in the longitudinal direction. The clearance is one seconds of a cycle d of a trigonometric function if correlation characteristics between the coordinate in the longitudinal direction and flux density of the magnetic field formed at an air gap is taken as the trigonometric function. Thus, the position detection sensor 1 with high detection accuracy is obtained irrespective of temperatures. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To suppress a detection error, even when a structure is adopted, wherein a tangential direction magnetic detection means is arranged between the outer fringe and the inner fringe of a discoid magnet as a view from a rotating shaft direction. SOLUTION: The discoid magnet 2 is provided elliptically as a view from the rotating shaft direction, and a completely-round shaft insertion hole 5 is provided on the rotation center, and further the tangential direction magnetic detection means is always arranged on a middle portion between the outer fringe and the inner fringe of the discoid magnet 2 by a sensor support means 4. Consequently, distortion of lines of magnetic force on a sensor locus α drawing an ellipse can be suppressed, and the detection error of a rotation angle can be suppressed. Since the detection error can be suppressed, correction of the detection error in a subsequent stage can be abolished or simplified, and reliability can be heightened, and cost can be suppressed. Further, a correction value of each angle is not required to be measured at a shipping time, to thereby shorten an adjustment time and heighten productivity. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：为了抑制检测误差，即使采用结构，其中切线方向磁检测装置设置在盘状磁体的外边缘和内边缘之间，作为从旋转轴方向的视图。解决方案：圆盘状磁体2从旋转轴方向看作椭圆形，并且在旋转中心设置有全圆形的轴插入孔5，并且切向方向磁检测装置总是布置在通过传感器支撑装置4在盘状磁体2的外边缘和内边缘之间的中间部分。因此，可以抑制绘制椭圆的传感器轨迹α上的磁力线的变形，并且旋转角度的检测误差可以抑制。由于可以抑制检测误差，因此能够消除或简化后续阶段的检测误差的校正，可以提高可靠性，能够抑制成本。此外，不需要在运送时测量每个角度的校正值，从而缩短调整时间并提高生产率。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fuel property sensor capable of lessening an error in fuel temperature detection.SOLUTION: A storage member 31 which stores a thermistor 41 for detecting fuel temperature is composed of a cylinder section 312 and a bottom section 311 blocking one end of the cylinder section 312. The storage member 31 is inserted into a continuous passage 214 of an external electrode 21 and a continuous hole 223 of an internal electrode 22, and is electrically connected to the internal electrode 22. A coating section 42 coating the thermistor 41 touches the bottom section 311 located on the side of the storage member 31 closest to the central axis φ. Thus temperature detected by the thermistor 41 is more influenced by a heat quantity transmitted to the thermistor 41 from the fuel than a heat quantity transmitted to the thermistor 41 from an outside environment. As a result, a detection error of fuel temperature detected by the thermistor 41 is made smaller.

摘要： PROBLEM TO BE SOLVED: To provide a rotational angle detecting device for correcting the output signal of a magnetic detection element in few man-hours, regardless of the rotational angle range of an object of detection, and to provide a rotational angle detection method.
SOLUTION: A yoke 20 and permanent magnets 22 and 24 are rotated with the object of detection being the object for detecting a rotational angle. Hall elements 30 and 32 are provided, to form an angle of 90 degrees in the rotational direction of the detection object, and a Hall element 34 has an angle of 45 degrees, forming in the rotational direction of the Hall elements 30 and 32 and the object of detection. In a state in which a magnetic field is not influenced, output signals of the Hall elements 30, 32 and 34 are read, to correct offsets. At a rotational angle position where output of offset corrected Hall element 34 is zero, gains of offset corrected Hall elements 30 and 32 are corrected so as to be matched. The rotational angle of the detection object is detected by reverse tangent calculation from outputs of offset correction and gain correction completed Hall elements 30 and 32.
