摘要： PURPOSE:To reduce the man-hour by using a nonmagnetic metal as materials of a cup-shaped case and a cover and welding flange parts of both of them by the cold pressure welding method. CONSTITUTION:A cup-shaped case 22 and a cover 23 using a nonmagnetic metal like aluminum are preliminarily annealed and degreased, and a permanent magnet 4 and a magnetic fluid 3 are put in them and they are fitted, and flange parts 22a and 23b are held between a top force 31 and a die 32. When the upper die 31 and the lower die 32 are pressed by a hydraulic press or the like, a projection 32a bites into the flange part 22a and the metal in the flange part flows as shown by an arrow to weld both flanges. A lead switch 7 as a magneto-sensitive element, a printed board 8, an amorphous piece 11 for adjustment of the response angle, etc., are combined to constitute an inclination sensor, thus not only reducing the man-hour for production but also improving the reliability of airtightness.

摘要： PURPOSE:To enhance not only the detection accuracy of a state of inclination but also manufacturing yield, by arranging the magnetic body exerting magnetical effect on a permanent magnet to the top part of a non-magnetic case and making the magnetical effect due to the magnetic body adjustable. CONSTITUTION:A reed switch 7 is mounted on a printed circuit board 17 along the orthogonal line thereof in order to detect the inclinations in P- and Q- directions by one reed switch 7 and the recessed groove 20 formed to the top part of a mount stand 15 is also formed in the same direction as the reed switch 7. When a magnetic body 10 is moved along the recessed groove 20 in this constitution, a response angle becomes small as the magnetic body is allowed to approach A and becomes large as said magnetic body is allowed to approach D. Since the response angle can be arbitrarily set by this mechanism, even when the mount position of a sensor constitutional part varies widely, the reed switch can be certainly operated at a set angle of inclination. As a result, the detection accuracy of a state of inclination and manufacturing yield can be enhanced.

摘要： PURPOSE:To reduce leakage flux and fluctuations in characteristics by tilting one set of magnetic legs so that their lines of extension is directed to the center of a rotary shaft with respect to the plane of a flat surface of the core and setting a print coil formed on the flexible base plate at the center of the magnetic legs. CONSTITUTION:While one set of magnetic legs 17a, 17b are erected upright from the flat plate of the magnetic core 17, the other set of magnetic legs 17c, 17d are tilted relative to the flat plate part so that the lines of extension thereof intersect the central axis 18 of the rotary shaft 18. The distance (w) between the legs 17c, 17d is set to a wider value so that the relation with the gap (g) between the end and the rotary shaft is represented by w>>2g. Even if the magnetic permeability of the shaft is s low as about 10, the magnetic reluctance of the magnetic circuit directly from pole to pole is larger surficiently than the magnetic reluctance of the magnetic path of the magnetic flux through the shaft 2. By further setting to the end of the magnetic leg the print coil provided to the flexible base plate of reduced thickness, flux leakage is reduced so that the magnetic flux can be concentrated to the rotary shaft.

摘要： PURPOSE:To accurately detect an inclination state through simple constitution by composing an inclination sensor of a permanent magnet which is provided in a case made of a nonmagnetic body having a space internally and can be displaced and a magnetic sensitive element fixed to the case. CONSTITUTION:The inclination sensor consists of the case 1 (including a lid 2) made of the nonmagnetic body having the space 3 internally, the permanent magnet 4 which has magnetic flux stuck on the surface and is stored in the space 3 in a displaceable state, and the magnetic sensing element 6 which senses the magnetism of the magnet 4 fixed to the case 1. Consequently, when the main case 1 is in a horizontal state, the magnet 4 is at the center part of the bottom surface 3 of the space by its own weight. Then when the bottom surface B slants, the magnet 4 moves to the lower part on the bottom surface A. Therefore, the magnet 4 moves away from the element 6 and their relative distance varies; and the magnetism corresponding to the distance is detected and the inclination of the device where the inclination sensor is installed can be detected. Further, the output of the element 6 is used to control the attitude of the device.

摘要： PURPOSE:To reduce resistance loss and eddy current loss while satisfying characteristics by making the sectional area of a magnetic core on which an output winding is wound smaller than that of a magnetic core on which an input winding is wound. CONSTITUTION:The sectional area of a magnetic core 3 on which an output winding 6 is wound is made smaller than that of a magnetic core 2 on which an input winding 5 is wound. For example, voltage applied to the input winding 5 is dropped up to a boosting and the output winding 6 is generated, and a discharge lamp D is started and lit. Winding length is short in the output winding 6 because the sectional area of the second magnetic core section 3 is relatively small, thus reducing resistance loss in the case when load currents flow through the output winding 6 only by the shortened section of winding length. Leakage flux is distributed centering around the gap of a magnetic core 1, but a winding interlinked with the leakage flux is also shortened only by the shortened section of winding length, thus reducing eddy current loss.
摘要翻译：目的：通过使卷绕有输出绕组的磁芯的截面积小于其上缠绕有输入绕组的磁芯的截面面积来满足特性，从而降低电阻损耗和涡流损耗。构成：使其上缠绕有输出绕组6的磁芯3的截面积小于其上缠绕有输入绕组5的磁芯2的截面面积。例如，施加到输入绕组5的电压下降到升压，并且产生输出绕组6，并且放电灯D开始点亮。由于第二磁芯部分3的截面积相对较小，所以输出绕组6的绕组长度短，从而在负载电流仅通过绕组长度的缩短部分流过输出绕组6的情况下减小电阻损耗。泄漏通量以磁芯1的间隙为中心分布，但是与漏磁通相互连接的绕组也仅由于卷绕长度的缩短部分而缩短，从而降低了涡流损耗。

摘要： PURPOSE:To reduce the eddy-current loss due to leakage flux by a method wherein a primary winding and a secondary winding are provided in parallel with each other with a gap between the main core and said windings, and a shunt core is provided in one body with the intermediate part between the primary and the secondary windings on the main core. CONSTITUTION:A main core consists of U type cores 1-1 and 1-2, and I type core 1-3 which is arranged between each leg part of said U type cores 1-1 and 1-2, and a gap is formed at each butting part of the U type cores 1-1, 1-2 and I type core 1-3. The shunt core 4 is provided in one body with the intermediary part of the primary winding 2 and the secondary winding 3 on the main core 1. As the shunt core 4 is provided at the I type core 1-3 of the main core 1, the number of interlinkage of the leakage flux phi1 flowing the shunt core 4 and the windings 2 and 3 is relatively small.
