摘要： A generator comprises a parallel plate capacitor which in turn is made up of a mobile plate and a stationary plate, the plates facing each other in parallel at their internal faces. The mobile plate moves up and down due to an external mechanical force to increase and decrease the gap between the plates, leading to a change in the capacitance between the mobile plate and the stationary plate. The internal faces of the plates have dielectric surfaces, for example formed by oxidizing. The generator is useful for example for small-scale mobile devices such as wearables, and to any device where motion is available to transform into electricity.

摘要： Embodiments disclosed herein generally include using a large number of small MEMS devices to replace the function of an individual larger MEMS device or digital variable capacitor. The large number of smaller MEMS devices perform the same function as the larger device, but because of the smaller size, they can be encapsulated in a cavity using complementary metal oxide semiconductor (CMOS) compatible processes. Signal averaging over a large number of the smaller devices allows the accuracy of the array of smaller devices to be equivalent to the larger device. The process is exemplified by considering the use of a MEMS based accelerometer switch array with an integrated analog to digital conversion of the inertial response. The process is also exemplified by considering the use of a MEMS based device structure where the MEMS devices operate in parallel as a digital variable capacitor.
摘要翻译：本文公开的实施例通常包括使用大量的小MEMS器件来代替单个更大的MEMS器件或数字可变电容器的功能。大量较小的MEMS器件具有与较大器件相同的功能，但是由于尺寸较小，因此可以使用互补金属氧化物半导体（CMOS）兼容工艺封装在腔中。通过大量较小器件的信号平均，允许较小器件阵列的精度等同于较大的器件。通过考虑使用具有惯性响应的集成模数转换的基于MEMS的加速度计开关阵列来举例说明该过程。还通过考虑使用MEMS器件结构（其中MEMS器件并行地作为数字可变电容器）来使用该过程。

摘要： The voltage-controlled variable-passband filter in accordance with the present invention is structured so that conductive patterns, R, L, and C, and other circuit elements are embedded in a ceramic substrate. Within this substrate is also embedded an insulating layer made of the same ceramic material, the capacitance of which changes in response to an electric field applied thereto. On one surface of the insulating layer is provided a control electrode, and on the other surface are provided adjacent to one another a resonator pattern, to which high-frequency signals are applied, and a ground pattern. Accordingly, two capacitors connected in series are formed between the resonator pattern and the ground pattern, and the capacitance of these series capacitors can be adjusted by an integrated circuit mounted on the ceramic substrate, thus reducing size and weight, and simplifying adjustment.

摘要： A chip component includes a chip component main body, an electrode pad formed on a top surface of the main body, a protective film covering the top surface of the main body and having a contact hole exposing the pad, and an external connection electrode electrically connected to the pad via the hole and having a protruding portion, which, in a plan view looking from a direction perpendicular to a top surface of the pad, extends to a top surface of the film and protrudes further outward than a region of contact with the pad over the full periphery of an edge portion of the hole. A method for manufacturing the component includes forming the pad on the main body's top surface, forming the protective film, forming the hole in the film so as to expose the pad, and forming the electrode electrically connected to the pad via the hole.
