Patent JP-H04130614-A (JP)
Title: Manufacture of laminated-chip inductor
Inventor: KIOKA YASUTETSU
IPC: H05K3/46
Filed: 1990-09-20
Abstract: PURPOSE:To prevent the L value from fluctuating under the influence of a magnetic field by a conductive paste composed chiefly of Ag2O powder. CONSTITUTION:Unburned magnetic substance sheets and conductive paste conductor patterns are laminated alternately, getting the conductor patterns 14, 14a, and 14b to be continuous between the magnetic substance sheets 12. Then, the laminated unburned sheets 12 and the patterns 14, 14a and 14b are burned to be changed into the magnetic substance and the electric conductor respectively. When burning, the substance, composed chiefly of Ag2O powder, is used for the conductive paste. Ag2O is reduced by burning and then Ag of smaller volume is left over. Also, spaces are formed on the boundary between the magnetic substance and the electric conductor. Therefore, when the magnetic substance and the electric conductor expand or shrink independently of each other under the influence of a magnetic field, no internal distortion occurs due to a difference in expansion coefficient between the magnetic substance and the electric conductor. Consequently, the L value hardly fluctuates owing to a magnetic field.

Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To reduce self excitation sound without changing a size of an exhaust duct or a distance between an engine and the exhaust duct in a self oscillation sound-reducing apparatus applied to a ground test drive equipment for the aircraft engine. SOLUTION: An engine 1 is suspended from an engine adapter 3 to confront an exhaust duct. A ground test drive is conducted in this state. A flange-type self excitation sound-reducing device 4 is fitted in the whole circumference of an exit end of an engine nozzle 2 thereby to increase a thickness of the exit end of the engine 2. During driving of the engine, eddies are continuously generated and a generation cycle is constant.
