摘要： An injection molding composition, having a small fluctuation characteristic and a better characteristic, is provided. The above composition is the injection molding composition comprising a ferrite powder which is a collection of ferrite particles, a first binder and a second binder. A weight and a specific surface area of the ferrite powders are represented by Wp and S, and a weight and a density of the first binder and the second binder is represented by Wb1, Wb2, and Db1, Db2. A hypothetical thickness Tb1 of the first binder is 2.0 to 15.0, and a hypothetical thickness Tb2 of the second binder is 16.5 to 32.0. In the composition, it is preferable that coated ferrite particles coating the outer circumference of the ferrite particles with the first binder and the second binder exist. Tb1 [nm]=(Wb1×103)/(Db1×Wp×S) formula (1) Tb2 [nm]=(Wb2×103)/(Db2×Wp×S) formula (2)

摘要： PROBLEM TO BE SOLVED: To provide a dielectric element, along with a method of manufacturing the same, of large capacity, with good leak characteristic. SOLUTION: The dielectric element 10 includes a substrate 12 and a dielectric film 18 stacked on the substrate 12. In the dielectric film 18, a first dielectric layer 14 and a second dielectric layer 16 comprising columnar crystal are stacked vertically to a substrate surface, and the columnar crystals contained in respective dielectric layers are discontinuous each other at a lamination interface. Since the columnar crystals in this dielectric element 10 are discontinuous at the lamination interface, occurrence of leak current at the crystal grain boundary of the columnar crystal is suppressed for improved leak characteristic of the dielectric element 10. Further, a plurality of dielectric layers contained in the dielectric film 18 comprise columnar crystal respectively, resulting in suppressed degradation of capacity. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a high quality electrochemical device capable of controlling the sharp point of the end of a lead, of making it hard to damage a resin layer with thickness of a specific range and upper and lower metal films, and of improving the tightness of a sealed packing unit. SOLUTION: The electrochemical device 10 includes: a packing unit P containing metal films, 20 battery elements included inside the packing unit, a resin layer arranged at least inside the sealing part of the packing unit, and a lead extending outside of the packing unit from the battery element through between the resin layers R1 and R2 of the sealing part. If we let L1 be a line segment that connects between one end of an arc in one direction of a curved surface of the lead and a point extending from this end and touching the lead, L2 be the maximum value of the shortest distance from the line segment to the curved surface of the lead, Z1 be the thickness of the lead, Z2 be the total thickness of the resin layers, and R be the curvature of the lead, then the following formulas are satisfied: 30%≤Z1/Z2≤60%, R=L2/L1, 0 COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a composition for injection molding having high flowability, capable of enhancing strength of a molded product, and to provide a method for producing the same.SOLUTION: This composition for injection molding includes ferrite powder which is an aggregate of ferrite particles, a first binder, and a second binder. In the composition for injection molding, a coated ferrite particle (20) is present, in which the outer circumference of a ferrite particle (10) is coated with the first binder (1) and the outer circumference of the first binder (1) is coated with the second binder (2). The first binder (1) is hydrophilic and the second binder (2) is hydrophobic, and the softening point of the second binder is lower than that of the first binder, and preferably wax (3) penetrates into the second binder. The composition for injection molding is produced by kneading the ferrite powder, the first binder and the second binder in this order, and then preferably wax is added thereto.

摘要： PROBLEM TO BE SOLVED: To provide a high quality electrochemical device and a method of manufacturing the same. SOLUTION: In this electrochemical device, leads A1(K1) have a plurality of notches DP1, DP2 (DP3, DP4) spaced along the longitudinal direction (X-axis) of the leads A1 (K1) at the positions of a sealing section P1. The notches DP1-DP4 have triangular shapes. In this case, the number of the notches DP1, DP2 (DP3, DP4) spaced in the longitudinal direction is plural and a resin of a resin layer encroaches on each of the notches, so that the leads are firmly embedded into the resin layer. Thus, the movement of the longitudinal direction of the leads can be sufficiently prevented. COPYRIGHT: (C)2011,JPO&INPIT
