摘要： A plasma display apparatus has an electronic circuit module including a rigid substrate attached to a chassis thereof and a flexible substrate partially overlapped with the rigid substrate. The rigid substrate has chips and the flexible substrate has a first portion with apertures for exposing the chips and bonding pads and a second portion positioned on the outside of the rigid substrate. Bonding wires connect terminals of the chips with the bonding pads of the flexible substrate. A reinforcing pattern or a dummy pattern is provided in at least the first portion of the flexible substrate. The reinforcing pattern provides for rigidity for the first portion of the flexible substrate for accurate positioning of the bonding pads relative to the chips.

摘要： A capacitance sensing section senses a capacitance between first and second electrodes. A temperature sensing section senses fuel temperature. A microcomputer functions as a concentration sensing section and senses a concentration of ethanol contained in fuel based on the capacitance sensed by the capacitance sensing section and the temperature sensed by the temperature sensing section. The microcomputer functions as an abnormality detecting section and performs abnormality determination to determine that an abnormality has occurred in the capacitance sensing section when the capacitance sensed by the capacitance sensing section does not change and the temperature sensed by the temperature sensing section changes. Since a dielectric constant has such a temperature characteristic that the dielectric constant changes with the temperature, the abnormality detecting section can detect occurrence of the abnormality in the capacitance sensing section.

摘要： According to the invention, there is provided a water cooled inverter structure forming a plurality of shallow cavities and deep cavities in a housing, fixing a bottom surface of power semiconductor modules to shallow cavities to form a shallow water channel and directly cooling the power semiconductor modules using this shallow water channel. Since cooling water flows fast in the shallow water channel, it is possible to improve a cooling efficiency and also reduce pressure loss using a deep water channel with deep cavities. Furthermore, providing a plurality of cavities makes it possible to reduce a size of the power semiconductor modules and provide a plurality of power semiconductor modules, thus improving reliability. It is possible to place a control board below the water channel to thermally cut off the control board from the power semiconductor modules, which makes it possible to reduce temperature of a control circuit.

摘要： A power inverter of the type used with hybrid electric vehicles having a circuit board with a power layer having a first and second section which are electrically separated using slits from each other on the power layer. A control circuit is connected to and powered by the first section of the power layer while a switching power supply is connected to and powered by the second section of the power layer. An electromagnetic filter is electrically connected between the sections of the power layer. This electromagnetic filter blocks high frequency noises of the type generated by the switching power supply while enabling the sections to be maintained at the same DC voltage level. Optionally, a ferrite covering is provided around a current bus bar of the power inverter to contain magnetic fields generated by current flow through the bus bar.
