Abstract: In a chip-type electronic component of the present invention, at least one surface of a ceramic body is a convexly curved surface. Specifically, at least one surface in a thickness direction of the ceramic body may be convexly curved, and the side surface of the ceramic body may be concavely curved. Alternatively, only one surface may be a convexly curved surface. This chip-type electronic component has a high visibility and a high mechanical strength, though it is small. Moreover, in a chip-type electronic component comprising a ceramic body that is formed by alternately laminating insulating layers and conductor layers, and a pair of external electrodes, the thickness in a laminate direction at the central part between external electrodes of the ceramic body is made greater than the thickness of the end surface. This prevents breakage of the external electrodes and also enlarges the ceramic body.

Abstract: By using the polarized electrode for electric double layer capacitor of the present invention, which is produced by mixing powdery activated carbon with a binder, and is characterized by the concentration of an organic compound being not more than 300 (ppm), the amount of organic compounds which remain in the pore of the powdery activated carbon decrease, and a possibility of forming the electric double layer by adsorption of electrolytic ion can be prevented. Thereby, an electric double layer is sufficiently formed inside the pore of the powdery activated carbon, and the diffusion resistance between the powdery activated carbon and the electrolyte becomes low. By constituting as such, an electric double layer capacitor with a large electrostatic capacity and a little internal resistance can be obtained.

Abstract: A capacitive light/dimmer switch which uses soft or fuzzy fabrics made with electronic textiles instead of, or as an extension of, metal or plastic plates. The soft fabric material, which may be in the form of a pompom, tassel, fur, or other electronic trim element, provides an attractive and compelling user interface that is soft to the touch. The user simply touches the pompom, as he would the dimmer plate, to cause the amount of light to increase or decrease. The electronic textiles of the light controller comprise electrodes integrated into their yarns or fibers, resulting in a conductive material (electronic textile) that may be used as the user interface. This conductive material is electrically connected to a sensing circuit by either AC coupling or DC contact. When the user touches the conductive material, the sensing circuit measures the change in load of the electrodes, and the lighting is changed.

The collector electrodes are composed of an alloy made of crystal grains of differing components and the collector electrodes pass through the sealing member while in intimate contact with the sealing member, extending to the outside of the sealing member. A metal plated layer made of crystal grains of a single component is formed on those locations on the collector electrodes that pass through the sealing member.

A driving electrode is arranged to displace the movable element, between a signal cutoff position and a signal passage position, whereby a high frequency signal transmitted through a transmission line is cut off or allowed to pass. The insulating film uses compressive stress to warp the movable element and the movable electrode in a direction of warping in a convex form toward the transmission line, and maintains this warping direction.
