Abstract: An electronic component and an electronic-component production method in which the magnitude of a stray capacitance produced between adjacent outer electrodes is controllable. The electronic component includes a chip body and first to fourth outer electrodes. In the chip body, first and second coil block are sandwiched between magnetic substrates. Dielectric layers are interposed between the outer electrodes and the chip body such as to be away from exposed portions of coil patterns in the coil blocks. The dielectric layers have a width larger than a width of the outer electrodes, and a dielectric constant of the dielectric layers is set to be lower than the dielectric constant of the magnetic substrates.

Abstract: A coil component includes a first coil block and a second coil block that are sandwiched between magnetic substrates so as to form a chip body, and external electrodes that are attached to the chip body. The first coil block includes a coil body and an insulating body. The coil body includes an outer coil portion and an inner coil portion. The outer coil portion includes a first pattern group and a second pattern group, which are connected helically vertically in an alternating fashion. The inner coil portion includes a first spiral pattern and a second spiral pattern, which are connected to each other in series. In other words, low stray capacitance is achieved by the outer coil portion, while high inductance is achieved by the inner coil portion.

Abstract: In a manufacturing process of electronic components which include conductive patterns laminated with insulating layers provided therebetween, conductive pattern layers having conductive patterns formed at intervals therebetween along layer surfaces and insulating layers are alternately laminated to each other. The laminate is pressed by applying a force thereto in the lamination direction, followed by cutting of the laminate along cutting lines provided along boundaries between the electronic components, so that the electronic components are separated from each other. In a cutting-removal region of a mother substrate from which the electronic components are separated from each other by cutting, removal dummy patterns having a size allowing it to be disposed within the above region are formed. In the electronic component, floating dummy patterns which are not electrically connected to the conductive patterns are formed at intervals from the cutting-removal region.

Abstract: In a foil bearing (23) having a plurality of foils (26) disposed in a gap between a rotating member (12) and a stationary mount member (25), a moveable member (27) is disposed on a side of the stationary member opposite to the rotating member so as to be rotatable with respect to the stationary mount member, abutting members (30) extend from the moveable member toward the associated foils through respective through-holes formed in the stationary mount member, and a surface of the moveable member with which one end of each abutting member is in contact is provided with a cam surface. In such a structure, by rotating the moveable member and thus changing the length of the abutting members projecting out from the surface of the stationary mount member, it is possible to vary the range of movement of the foils and practically vary the stiffness of the same.

Abstract: In a foil bearing (23) having a plurality of foils (26) disposed in a gap between a rotating member (12) and a stationary mount member (25), a circumferentially extending portion of each foil and a moveable member (27) rotatable with respect to the stationary mount member are provided with magnets (30, 31) so that a magnetic force between these magnets urges the foils toward the rotating member. By rotating the moveable member to vary the relative circumferential position of the moveable member with respect to the foils, it is possible to adjust an amount of magnetic force between the magnets of the moveable member and the magnets of the foils.

Abstract: The present invention provides a miniature gas turbine engine for power generation. The engine has a highly integrated unitary rotor shaft where turbine, compressor and shaft are made in one piece in one fabrication process. The turbine and compressor are positioned back to back on the shaft in an overhung configuration, allowing the front bearings to be located in the cold zone of the engine. Preferably, the Mold SDM fabrication technique is utilized to make the unitary rotor shaft in one monolithic part out of ceramics such as silicon nitride, eliminating the need for post process assembly while strengthening the integrity, reliability, and performance of the unitary rotor shaft. Integrated with a permanent magnet in the unitary rotor shaft, the miniature gas turbine engine can generate electric power of 1 kW or less. Additionally, the axial length of the miniature gas turbine engine is about 100 mm or less.

Abstract: In a permanent magnet rotor, a power transmitting shaft is connected to an axial end of a solid cylindrical permanent magnet, and a reinforcement sleeve is fitted on the outer circumferential surface of the permanent magnet. Thus, the shaft is not required to be passed through the permanent magnet as was the case with the conventional permanent magnet rotor for the purpose of transmitting the rotational torque and increasing the overall rigidity, and the increase in the axial dimension of the rotor due to the reduction in the cross sectional area of the permanent magnet can be avoided. Also, because the sleeve surrounds the permanent magnet, the resistance to centrifugal stress resulting from a high speed rotation and repeated bending stress owing to vibrations can be improved.

Abstract: In a micro gas turbine engine, a capacitive sensor is used for measuring a tip clearance of a radial compressor section thereof, and an actuator is used for axially displacing a rotor shaft in response to an output from the capacitive sensor. Because the capacitive change gives an accurate measure of the size of the tip clearance, a particularly high sensitivity can be achieved in parts where the tip clearance is small, thereby providing a highly precise tip clearance control.
