The present invention addresses the problem of providing a new magnetic material with which further improvement in magnetic permeability is effected, and of providing a coil component employing such a magnetic material. According to the present invention, a magnetic material is provided wherein: a particle molding body (1) is provided in which a plurality of metallic particles (11) formed from an Fe-Si-M soft magnetic alloy (where M is a metallic element which oxidizes more readily than Fe) are molded; at least a portion of the periphery of each of the metallic particles (11) has oxide films (12) obtained by oxidizing the metallic particles (11); the particle molding body (1) is molded primarily through the bonding of the oxide films (12) which are formed on the peripheries of the respective adjacent metallic particles (11). The apparent density of the particle molding body (1) is 5.2g / cm3 or more, and is preferably 5.2-7.0g / cm3.

The purpose of the present invention is to effectively prevent, using a very simple structure, power leakage caused by dew condensation water or the like by increasing a creeping distance of a batterycell bottom surface. Provided is a power supply device that comprises: a plurality of battery cells (1) having a square outer shape; separators that are arranged between the battery cells (1); a pairof end plates that are disposed at the two ends of a battery multilayer body that is formed by stacking a plurality of the separators and the battery cells (1) on top of one another; and a binding bar that binds the pair of end plates to each other. The separators are provided such that insulating rib parts (21) thereof, which are disposed on bottom surfaces of the battery cells (1) stacked at both sides, are provided so as to protrude toward both surfaces, and the insulating rib parts (21) of the separators, which are stacked on both surfaces of the battery cells (1), are stacked on the bottom surfaces of the battery cells (1). An insertion rib (23), which is provided on one stacked insulating rib part (21), is inserted into an insertion groove (22), which is provided in another stackedinsulating rib part (21), the insulating rib parts (21) are stacked one top of the other, and the insulating rib parts (21), which have a curved U shape creeping distance, are disposed on the bottom surfaces of the battery cells (1).

The invention provides a conductive anode oxidation technology of aluminum and alloy parts thereof, which comprises the following steps: (a) alkaline corrosion: the aluminum and the alloy parts are put into an alkaline solution for removing an oxide skin generated in natural state; (b) bright dipping: the aluminum and the alloy parts are put into 40 to 70 percent nitric acid solution for removingthe dust so as to lead the aluminum and the alloy parts to expose metal luster; (c) anode oxidation: the aluminum and the alloy parts are put into a mixed electrolytic solution prepared by chromic salts and villaumite, 10 to 35V of voltage and 0.5 to 5A / dm<2> anodic current density are exerted to the solution at normal temperature, and the time for anode oxidation is 5 to 30min; and (e) drying. Afilm layer presents slightly transparent rainbow color and is bright, and has smooth and compact appearance. The technology has excellent welding performance, good electric conductivity and better antirust property, and solves the contradiction between the aluminum and the alloy parts, and the electric conductivity and the welding performance.

The invention is applicable for the technical field of electronics, and provides a light touch switch type key circuit, which comprises a power supply (Vcc), a resistor (R1) and a resistor (R2). The key circuit further comprises an electronic switch and a light touch switch (K1), wherein the light touch switch (K1) is connected with an input end of the electronic switch; after the resistor (R1) and the resistor (R2) are connected in series, one end of the resistor (R1) and one end of the resistor (R2) are connected with the power supply (Vcc), while the other ends are connected with an outputend of the electronic switch; the light touch switch (K1) is used for controlling the on-off of the electronic switch through the on-off of the light touch switch (K1); and the electronic switch is used for outputting a control signal. Through the technical scheme in the invention, a light touch switch type key still can be normally used if insulation resistance thereof is decreased much or contact resistance is increased much, so that the working reliability of equipment is greatly improved, the degree of satisfaction of users is improved, after-sales complaints about the failure of the key are greatly reduced, and the maintenance cost is saved.
