摘要： Reduction of noise is achieved by devising an arrangement of heat generating parts such as a light valve element, an electric power source, a light source, etc. and an arrangement of cooling fans. In cooling the light source, the electric power source and liquid crystal panels, a cooling wind path for the liquid crystal panels and the electric power source is made separate from and independent of a cooling wind path for the light source that generates much heat, a cooling air volume is optimized for the respective cooling wind paths, and noise accompanying the rotation of the cooling fans is reduced. Also, by arranging the cooling fans substantially centrally of the respective cooling wind paths, that volume of noise, which leaks from air intake ports and air exhaust port that are opened to a housing of a unit, is reduced.

摘要： A material of a gate electrode is a conductive oxide having a higher work function than that of conventionally used Pd and so on, thereby achieving a normally-off transistor without reducing the sheet carrier concentration of a heterojunction. It is thus possible to achieve a normally-off operation while reducing an increase in the specific on-state resistance.

摘要： In an active matrix display device integrated with a peripheral drive circuit using thin film transistors, when Vgr is a voltage required for one gradation, Ct is capacitance of all pixels, Cgd is capacitance between a gate and a drain, .DELTA.Vg is a difference between ON/OFF gate voltages, and .DELTA.Vs is a feedthrough voltage, the respective parameters satisfy an expression: .vertline.vgr.vertline.>.vertline.(1/Ct)[Cgd.multidot..DELTA.Vg-Ct.multidot..DELTA.Vs].vertline.. According to this, even if dispersion occurs in the characteristics of the thin film transistors arranged for a buffer circuit or an active matrix circuit, it is possible to prevent the dispersion from influencing the gradation display.

摘要： A system and method for controlling an ignition timing for an internal combustion engine mounted in a vehicle are disclosed in which a limit value for the ignition timing value is provided so that a difference between a current ignition timing and a previous ignition timing is within the limit value and the limit value is set according to a magnitude of an engine acceleration. For example, when an abrupt engine acceleration occurs, the limit value is set to 15 degrees. When the engine is in a steady state (no abrupt acceleration from an idling condition), the limit value is set to four degrees. Therefore, no vehicle body shock occurs due to the abrupt change in an engine output torque caused by the abrupt change in the ignition timing and a response characteristic of a rise in the engine output torque during the abrupt acceleration can be assured.

摘要： A motor driving circuit includes a three-phase inverter circuit 8, including three upper-arm switching elements 56a to 56c for driving upper arms of different phases of a three-phase motor 3, and three lower-arm switching elements 56d to 56f for driving lower arms of different phases. At least one of the upper-arm switching elements 56a to 56c and the lower-arm switching elements 56d to 56f is a semiconductor element that performs a diode operation. The diode operation is an operation in which a voltage less than or equal to a threshold voltage of a gate electrode G is applied to the gate electrode G with reference to a potential of a first ohmic electrode S, thereby conducting a current flow from the first ohmic electrode S to a second ohmic electrode D and blocking a current flow from the second ohmic electrode D to the first ohmic electrode S.

摘要： A bidirectional switch comprises a first FET, a second FET, and a switch controller for controlling a conductive state in which current from a bidirectional power supply electrically connected to drain terminals bidirectionally flows, and a nonconductive state in which the current does not flow. In the conductive state, the switch controller applies, to gate terminals of the first FET and the second FET, a voltage higher than a threshold voltage with reference to a potential at a node to which source terminals of the first FET and the second FET are connected. In the nonconductive state, the switch controller causes the bidirectional power supply and each gate terminal to be electrically insulated from each other, and applies a voltage lower than or equal to the threshold voltage with reference to the potential at the node.
