The second side face may be formed with a second protruded part around which the second coil is wound, the second protruded part being protruded to an outer peripheral side with respect to the coil holding member. The first coil and the second coil may be structured from one conducting wire. | 12-03-2015 |
| 20160027578 | METHOD OF MANUFACTURING MULTILAYER BOARD, MULTILAYER BOARD, AND ELECTROMAGNET - In a linear conductor forming step, a wide portion having a relatively large line width and a narrow portion having a relatively small line width are formed in each of a plurality of linear conductors. In addition, in a multilayer board, in base material layers adjacent to each other in a stacking direction, the wide portion overlaps the narrow portion on the adjacent base material layer, and end portions of the wide portions at both sides of the narrow portion in a line width direction, in a planar view. The wide portions are disposed such that the end portions thereof overlap each other in the stacking direction and resistance of a fluid thermoplastic resin increases. The narrow portion is located between the wide portions in the stacking direction. | 01-28-2016 |

| 20120242437 | ELECTROMAGNET DRIVE FOR A VALVE - An electromagnet drive for a valve includes a piston element. A housing comprises an electromagnetic circuit, a coil wound onto a coil former, an armature mounted to move between a first and second end position to act on the piston element, a core, and a magnetisable return device. The core and/or the magnetisable return device comprises an adjusting bore. The core or the magnetisable return device comprises a substantially circumferential cutout in a region of the adjusting bore on a side facing the coil. A fixing device fixes the armature in a non-energized state. An adjusting device adjusts a magnetic force. The adjusting device comprises an adjusting screw which influences a profile of magnetic field lines. The adjusting screw is insertable into the adjusting bore of the core or the magnetisable return device in a direction of the armature. Energizing the coil moves the armature into the first or second end position. | 09-27-2012 |
| 20150302967 | MULTILAYERED ELECTROMAGNETIC ASSEMBLY - A multilayered electromagnetic assembly. The assembly has a plurality of substantially planar substrate layers, each substrate layer having a cutaway portion. An insulated electrically conductive material is provided, arranged in a spiral configuration on at least two of the substrate layers. The spiral configuration is formed from adjacent the cutaway portion to the edges of the substrate layer. The electrically conductive material is formed substantially on and/or partially recessed or beneath the surface of the substrate layer. The spiral configurations has first and second electrical contacts that are operable to pass electric current to electrical contacts of spiral configurations on other substrate layers. A ferromagnetic core is located through the cutaway portions of the substrate layers. The substrate layers are stacked and an electrical current is passed sequentially through the two or more spiral configurations, thereby generating a magnetic field in the core. | 10-22-2015 |
