A circuit protecting element includes insulating substrate (), a pair of surface electrodes () provided to both ends of a top face of insulating substrate (), element () bridging the pair of surface electrodes () and electrically connected to the pair of surface electrodes (), base layer () formed between element () and insulating substrate (), and insulating layer () covering element (). Base layer () is formed of a mixture of diatom earth and silicone resin. The structure discussed above allows stabilizing the blowout characteristics of the circuit protecting element.

Circuit protective device and method for manufacturing the same

A surface mount current fuse of the present invention includes a first base which has a recess and is smaller in width at the other end than at one end in the longitudinal direction, and a second base which has the same shape as the first base. The first base and the second base are combined to form a box-shaped body by joining the lower surface of the second base to the upper surface of the upper surface of the first base in such a manner that one end of the first base and the other end of the second base are in contact with each other. The recess of the first base and the recess of the second base form a space portion in which to dispose an element portion. The borderline between the first base and the second base passes through the center point on a side surface of the body. As a result, the surface mount current fuse has high production efficiency.

Surface-mount current fuse

An electronic component is provided in which: impact-absorbing layers are provided so as to cover at least the corner portions of both end portions of a base which is made of an insulating mixture of ceramic and glass; a conductive film is formed so as to cover the surface of these impact-absorbing layers and the surface of the base; the portions of this conductive film which cover the surfaces of the impact-absorbing layers are formed into electrodes; and a resistance-adjusting groove is provided in an other portion of the conductive film than the portions serving as the electrodes.

Noise filter and electronic device using noise filter

A ceramic electronic component includes two or more electrodesandspaced at a predetermined distance from each other, between which a potential difference is produced in operation and a voidthat penetrates to the outside is provided. In the void, a water repellent filmis formed. This prevents water vapor from being absorbed in the voidconnecting the electrodesand, and thereby preventing the formation of a conductive path and the occurrence of ion migration.

In a noise filter having a large impedance in a common mode, a first conductor and a second conductor provided on first magnetic sheets and have spiral shapes of plural turns and spaced from each other for avoiding short-circuit. The first conductor is provided inside the spiral shape of the second conductor. The other end of the first inner conductor is located adjacent to the other end of the second inner conductor. The respective other ends of the first inner conductor and the second inner conductor on the magnetic sheet are connected at the respective other ends to first and second conductors provided on another magnetic sheet.

Noise filter and electronic apparatus comprising this noise filter

A ceramic electronic component includes two or more electrodes and spaced at a predetermined distance from each other, between which a potential difference is produced in operation and a void that penetrates to the outside is provided. In the void , a water repellent film is formed. This prevents water vapor from being absorbed in the void connecting the electrodes and , and thereby preventing the formation of a conductive path and the occurrence of ion migration.

In a positive electrode for an alkaline storage battery, a layer is formed between a porous substrate as a core material and an active material including nickel hydroxide filled into the porous substrate. The layer includes an oxide containing cobalt and nickel and/or a hydroxide containing cobalt and nickel. In the hydroxide, the average of an oxidation number of a metal is more than +II. The layer has a high electric conductivity while keeping the high corrosion resistance. A utilization rate of the active material can be improved due to the high electric conductivity. An alkaline storage battery including such an electrode has a good cycle property.
