摘要:
An antenna device and non-contact transmitter/receiver device constituting at least the same includes a first conductor unit; a second conductor unit that is electrically connected to the first conductor unit; and a third conductor unit that is electrically connected to the first conductor unit and the second conductor unit. The first conductor is placed along a first virtual plane, the second conductor unit is placed along a second virtual plane, and the third conductor is placed along a third virtual plane. In this antenna, the plane that includes the first conductor unit, the plane that includes the second conductor unit, and the plane that includes the third conductor unit are perpendicular to one another.
摘要:
An inductor and a method of manufacture results in external electrodes that prevent generation of flashes. The inductor has a ferrite substrate, external electrodes, and a coil. The cross-sectional area of the external electrodes extending across the cutting line is reduced to suppress generation of flashes during the cutting process. Pairs of through-holes are formed at positions in line symmetry about the cutting line. A connection conductor is formed in each of the through-holes, and the external electrodes are formed on the front and back surfaces of the substrate, with the connection conductor connecting each of the pairs of external electrodes on the front and back surfaces. Through-holes can be oblong holes extending across the cutting line, and the external electrodes can extend away from the cutting line.

In one embodiment, a semiconductor device having single or multi-layer intermediate layers that easily adhere to a glass frit and lead lines of respective interconnections is disclosed. In general, the single or multi-layer intermediate layers are formed on at least the top surfaces of portions of the respective lead lines on which the glass frit is placed.

A thin plate-shaped substrate 21 comprised of a monocrystal is provided with a piezoelectric element 24, and both ends of a movable piece 20 whose one surface is provided with a movable contact 25 are fixed and supported to a base 11. Then, by curving the movable piece 20 via the piezoelectric element 24, the movable contact 25 is brought in and out of contact with a pair of fixed contacts 38 and 39 that face the movable contact. With this arrangement, a subminiature micro-relay having a mechanical contact mechanism that has a small resistance in turning on the contact and the desired vibration resistance, frequency characteristic and insulating property can be obtained.
