Abstract:
Disclosed is a method for manufacturing a double-sided printed circuit board (PCB) having a circuit pattern by printing a conductive paste. According to the method of the present invention, a circuit pattern that is precise and highly conductive can be formed, and a reduction in raw materials and the simplification of processes are made possible. Also, due to the printing of the conductive paste, short-circuit can be prevented even when a conductive layer is bent or exposed to heat or physical impact.

Abstract:
An exhaust pipe structure of a vehicle having a left manifold disposed in front of an engine and a right manifold disposed behind the engine along a longitudinal direction of the vehicle, which are connected by an underbody catalytic converter, the exhaust pipe structure may include a left exhaust pipe connected to the left manifold and extending toward the rear of the engine, a right exhaust pipe having a straight portion connected to the right manifold and extending toward the front of the engine and a curved portion bending from the straight portion toward the rear of the engine, and a conjunction, one end of which is connected to and communicates with the end of the curved portion of the right exhaust pipe and the end of the left exhaust pipe and the other end of which is connected to the underbody catalytic converter.
Abstract:
A method of making Y-type hexagonal ferrite and an antenna using the same are provided. Y-type hexagonal ferrite includes a base ferrite composed of iron oxide, barium carbonate and cobalt oxide, and silicate glass ranging from 0.5 to 5 weight percent added to 100 weight percent of base ferrite. An antenna apparatus includes a magnetic carrier and an antenna pattern formed thereon. The magnetic carrier is formed of such Y-type hexagonal ferrite, and the antenna pattern resonates in a specific frequency band when electric power is supplied. To fabricate the Y-type hexagonal ferrite, a calcination process is performed in which iron oxide, barium carbonate and cobalt oxide are combined into base ferrite at a given calcination temperature after being mixed. A sintering process is performed to sinter the base ferrite and the silicate glass at a given sintering temperature which is lower than the calcination temperature after adding the silicate glass to the base ferrite.
