Nippon Chemi-Con Corporation is a Japanese corporation that produces electrolytic capacitors. Nippon Chemi-Con was founded in 1931 by Toshio Satoh as the first electrolytic capacitors production in Japan.Their capacitors are used in many motherboards including DFI, and PSUs from Zippy Technology and Seasonic. Currently they are considered one of the best capacitor makers, along with Hitachi, and their reputation is a selling point for top of the line PSU brands like PC Power and Cooling, Enermax, BFG Technologies, Sea Sonic, Antec, SilverStone Technology and others.Today Nippon Chemi-Con still dominates the Global Aluminum Electrolytic industry as the largest producer and is poised to expand their business and influence in the capacitor industry with their many new developments including Conductive Polymer Capacitors, Ultra-Capacitors and Ceramic Capacitors.

The present invention provides a coil and a method for manufacturing the same using a high magnetic permeability material such as an amorphous material for a core so as to achieve a shortened circling length of a coil conductor and a lower resistance as well as a higher inductance. The coil comprises first and second cores (4-1, 4-2) including through-holes in parallel for allowing penetration of coil conductor pieces (8-1, 8-2) made of a high magnetic permeability material, cases (core cases 6-1, 6-2) in which the first core and the second core are stored, and a coil conductor made up of the plurality of coil conductor pieces and circling between the first and second cores such that at least one end part of one of the coil conductor pieces (8-1) penetrating the through-holes (12) of the first core and the second core is coupled to an end part of the other coil conductor piece (8-2) on the outside of the cases.


Provided is an electrode which gives an electric storage device that has high energy density and good cycle life. This electrode for an electric storage device is characterized by having an active material layer that contains: an electrode active material particle; and a paste-like conductive carbon that is derived from an oxidized carbon obtained by giving an oxidizing treatment to a carbon raw material with an inner vacancy and covers a surface of the electrode active material particle. The paste-like conductive carbon derived from the oxidized carbon is densely filled not only into a gap that is formed between the electrode active material particles adjacent to each other but also into a pore that exists on the surface of the active material particle, so that the electrode density is increased, thereby improving the energy density of the electric storage device. In addition, since the paste-like conductive carbon suppresses dissolution of the active material, the cycle characteristics of the electric storage device are improved.


Provided is conductive carbon that gives an electrical storage device having a high energy density. This conductive carbon includes a hydrophilic part, and the contained amount of the hydrophilic part is 10 mass% or more of the entire conductive carbon. When performing a rolling treatment on an active material layer including an active material particle and this conductive carbon formed on a current collector during manufacture of an electrode of an electric storage device, the pressure resulting from the rolling treatment causes this conductive carbon to spread in a paste-like form and increase in density. The active material particles approach each other, and the conductive carbon is pressed into gaps formed between adjacent active material particles, filling the gaps. As a result, the amount of active material per unit volume in the electrode obtained after the rolling treatment increases, and the electrode density increases.


Although a conventional composite body of lithium vanadium phosphate and a conductive carbon material exhibits a favorable discharge capacity when the discharge rate is less than 80 C, there is a problem that this composite body has a low discharge capacity when the discharge rate is 80 C or higher. Provided is cathode material including lithium vanadium phosphate including vanadium with a valence that changes between 3 and 5 due to removal and insertion of lithium ions and conductive carbon material. The lithium vanadium phosphate is bonded to a surface of the conductive carbon material, and 90% or more of the lithium vanadium phosphate by total weight is particle-shaped crystals with diameters from 10 nm to 200 nm.

A capacitor comprises a capacitor element having electrode foils on the anode side and the cathode side laminated via separators, connecting parts of terminal components being disposed inside a laminated portion of the electrode foils and the separators, the connecting parts being connected to the electrode foils on the anode side and the cathode side; and a case that includes a storage part storing the capacitor element and having an opening portion sealed by a sealing body, that has a crimped part crimped from the outside of the storage part toward a side surface of the capacitor element, and that holds the capacitor element with the crimped part. The case is crimped to form the crimped part while avoiding a position at which the electrode foils of the capacitor element in the storage part overlap with tip portions of the connecting parts of the terminal components. The vibration resistance of the capacitor element can be consequently improved to prevent a damage of the terminal components and achieve the stability of operation of the capacitor.

A production method for an electronic component using an exterior packaging material containing a silicone resin comprises a step of dipping an element into an exterior packaging material containing a silicone resin to which aluminum hydroxide or magnesium hydroxide and a nonpolar solvent are added, an additive amount of the aluminum hydroxide or the magnesium hydroxide being controlled to a range of 60 [wt.%] or more to less than 70 [wt.%], a step of drying the exterior packaging material formed on a surface of the element to evaporate the nonpolar solvent and cause a silicone resin component to appear on a surface of the exterior packaging material, and a curing step of curing the exterior packaging material. As a result, the silicone resin can be reduced while maintaining the incombustibility and insulation withstand voltage of the exterior packaging material.
