摘要： PROBLEM TO BE SOLVED: To provide an electronic component module which satisfies both of the short height and high density, while securing versatility and extensibility. SOLUTION: The electronic component module 100a is constituted of a passive component 10a mounted on a built-in IC substrate 50. The passive component 10a is provided with a passive element inductor 12a and a mounting surface 14 for mounting on a substrate. Recesses 16a are respectively provided at parts of two facing borders in the mounting surface 14, and a terminal electrode 18a is provided at the bottom parts of the recesses 16a. Since the passive component 10a has a recess 16a inside the mounting surface 14 and the terminal electrode 18a is incorporated within this recess 16a, the passive component 10a can be mounted low on the substrate surface. Since the terminal electrode 18a is incorporated in the recess 16a, solder is prevented from spreading into a fillet shape at the periphery of the inductor, and the mounting density of the passive component 10a is enhanced. Flexibity in mounting the passive component is enhanced, because the passive component 10a is mounted on the built-in IC substrate 50 in which the IC 53 is embedded. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：提供满足短高度和高密度两者的电子部件模块，同时确保多功能性和可扩展性。解决方案：电子部件模块100a由安装在内置IC基板50上的无源部件10a构成。无源部件10a设置有无源元件电感器12a和用于安装在基板上的安装表面14。凹部16a分别设置在安装表面14的两个相对边界的部分处，并且端子电极18a设置在凹部16a的底部。由于被动元件10a在安装表面14内部具有凹部16a，并且端子电极18a被结合在该凹部16a内，所以无源部件10a可以被安装在基板表面上。由于端子电极18a被结合在凹部16a中，所以防止了在电感器的周围使焊料扩散成圆角状，能够提高无源部件10a的安装密度。由于被动元件10a安装在嵌入有IC 53的内置IC基板50上，因此增强了安装无源元件的灵活性。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a noise filter and a compound coil that can be used as a component of it, of which the variation in performance caused by a difference of manufacturing conditions is suppressed for stable frequency characteristics, and which is easy in manufacturing.
SOLUTION: A third winding 13 is wound on a part of the outer peripheral surface of a first core 40 where first and second windings 11 and 12 are wound. Therefore, compared to the case that the third winding 13 is wound on a separate third core, the number of components is decreased and a variation in performance caused by a difference of manufacturing conditions of cores is suppressed, resulting in stable frequency characteristics. A first core 40 and a second core 50 are arranged side by side so that parts of outer peripheral surfaces of them face one another. By adjusting an interval D between the facing outer peripheral surfaces and facing areas, an inductance value L3 can be easily adjusted by the third winding 13.

摘要： PROBLEM TO BE SOLVED: To increase the transmission quantity of signals per unit time with suppressing the transmission power and suppress the signal interference with other electric apparatus or broadcast waves, etc.
SOLUTION: A gain controller 10 variably controls the level of transmission signals matched with the phase of an AC power source voltage. For example, based on data D2 concerning with a detected noise level, the level of the transmission signal is variably controlled so that the level of the transmission signal is relatively low in a first phase section with a relatively low noise level on the AC power source voltage, but relatively high in a second phase section with a relatively high noise level. The data D2 of the noise level may be acquired periodically to periodically correct the level of the transmission signal.

摘要： PROBLEM TO BE SOLVED: To enable reduction of noises etc. and amplification of a reception signal by attenuating a transmission signal as necessary with a simple configuration without adding a circuit such as an attenuator on a single processing circuit side.
SOLUTION: The number of turns N2 of a secondary side wiring 11-2 of an insulating transformer 11 is configured so as to be smaller than the number of turns N1 of a primary side wiring 11-1, and an impedance Z2 of the secondary side is set so as to be smaller than an impedance Z1 of the primary side. Since such an impedance characteristic is provided, the amplitude level of a signal to be transmitted from the primary side of the insulating transformer 11 to the secondary side thereof is attenuated. On the contrary, the amplitude level of a signal to be transmitted from the secondary side to the primary side is amplified.
