摘要:
A power supply apparatus for a vehicle supplies/charges electric power to/from a power supply unit. The vehicle includes a first power-inverter circuit, a capacitor, high-resistance and low-resistance electric-paths between the capacitor and a battery, a first switching unit opening/closing the electric-paths, and a unit operating the first switching unit, when connecting between the battery and the first power-inverter circuit, in such a manner that after the high-resistance electric path is closed and the low-resistance electric path is opened, the high-resistance electric-path is opened and the low-resistance electric-path is closed. The apparatus includes an electric power transferring electric-path, an operating unit operating the first power-inverter circuit to supply/receive electric power to/from the power supply unit, and a prohibiting unit prohibiting the electric-path between the power supply unit and the first power-inverter circuit from closing when the amount of charge of the capacitor is equal to or less than a predetermined value.

Base insulating layers are formed on a support substrate having a conductive property. The support substrate is etched, to form support substrate board and a plurality of conductive portions in a suspension board. The holding piece and the conductive portions constitute a shape determination unit. The conductive portions have first to fifth conductive portions. The third and fourth conductive portions are spaced apart from each other, and the fifth conductive portion is formed between the third and fourth conductive portions. The first and second conductive portions are respectively formed integrally with one end and the other end of the fifth conductive portion. It is determined whether the first and second conductive portions in the shape determination unit are connected electrically to each other. And it is determined whether the first and third conductive portions are connected electrically to each other.

A dummy trace portion is provided in a region between at least a suspension board with circuit on one end side and a support frame of a suspension board assembly sheet with circuits. A base insulating layer is formed on a support substrate in the dummy trace portion. A plurality of conductor traces are formed on the base insulating layer, and a cover insulating layer is formed on the base insulating layer to cover each conductor trace. At least one of the base insulating layer and the cover insulating layer in the dummy trace portion has a groove.

An end of a first line and an end of a second line of a first write wiring pattern are arranged on both sides of a third line of a second write wiring pattern. Circular connection portions are provided at the ends of the first line and the second line. Through holes are formed in portions of a cover insulating layer above the connection portions, respectively. First connecting layers made of copper, for example, are formed to fill the through holes of the cover insulating layer. A substantially rectangular second connecting layer made of copper, for example, is formed to integrally cover upper ends of the connecting layers. This causes the first and second lines to be electrically connected to each other through the first and second connecting layers.
