摘要： A laminated chip-type LC filter for use as a noise filter is obtained by carrying out the following steps: dielectric layers are laminated on the top and bottom of a magnetic material layer, forming an inductor portion by providing conductive lines inside the magnetic material layer and forming capacitors by providing at least two layers of parallel internal electrodes inside both of the dielectric layers. External electrodes are provided at both ends of the inductor portion. Intermediate external electrodes are provided at both lateral sides in the middle part of the dielectric layers and the magnetic layer. The inductor portion is connected to the external electrodes. The internal electrodes are connected to the intermediate external electrodes and to the external electrodes, respectively. By making the intermediate external electrode the ground, the internal electrodes are grounded so that stray capacitance does not arise between the internal electrodes thus causing less deterioration of the insertion loss characteristic in the high-frequency area.

摘要： An LC filter comprises a ceramic laminate which has at least one dielectric part defining an exposed surface and at least one magnetic part integrated with the dielectric part in a layered manner. The ceramic laminate is provided with at least one through hole which has a first opening positioned on the exposed surface of the dielectric part and commonly passes through both of the dielectric part and the magnetic part. A connector pin is inserted in the through hole while a first electrode of a capacitor is formed on the exposed surface in a peripheral region of the first opening to be electrically connected with the connector pin. A second electrode of the capacitor is provided to be opposite to the first electrode through a dielectric member forming the dielectric part except for a peripheral region of the through hole, so that the second electrode is extracted toward the exterior of the ceramic laminate as a grounded electrode.

摘要： A high-voltage capacitor is not deteriorated by any of a laser medium gas, ultraviolet rays, and discharge plasma of a gas laser device. Inside a hermetic casing is stored a capacitor body having an electrode which is connected to an external terminal. The external terminal includes a passageway therein which makes the inside of the hermetic casing communicate with the outside of the hermetic casing. The external terminal is led to the outside of the hermetic casing from the capacitor electrode, and gas inside the hermetic casing is discharged through the passageway of the external terminal to achieve a reduced pressure. Thereafter, the inside of the hermetic casing is filled with an insulating protection material. With the hermetic casing being made of alumina and the electrode terminal plated with nickel, deterioration due to ultraviolet rays or discharge plasma generated by an electric discharge of the laser device is prevented, thereby not contaminating the ambient gas.
