摘要:
A vehicle lamp unit includes a reflective surface based on an ellipse; a semiconductor light source of which a light emitting portion is provided at a first focal point of the reflective surface or a vicinity of the first focal point; and a projection lens that projects a reflected light that is a light emitted from the semiconductor light source and reflected by the reflective surface to outside. An emission direction of a maximum light emission intensity from among light intensities of the semiconductor light source is inclined in a direction opposite to the projection lens with respect to an optical axis of the projection lens.

To measure noise generated within a semiconductor device at a high speed and at high accuracy. A semiconductor device 1 includes an output driver circuit 5 for generating noise on wiring for a power supply Vdd targeted for noise measurement using a trigger signal S input from measuring equipment 2 and a noise measuring circuit 3. The noise measuring circuit 3 includes a comparator circuit for comparing a voltage on the wiring for the power supply Vdd with a reference voltage Vref supplied from the measuring equipment 2 and outputting a result of comparison, and two latch circuits for respectively holding the change of the result of comparison to one state and the change of the result of comparison to the other state, for output to the measuring equipment. The measuring equipment 2 for measuring the noise in the semiconductor device changes the reference potential Vref, monitors times from a change of the trigger signal S which becomes a trigger for noise generation, to changes of output signals OUTP and OUTN of the two latch circuits, and plots the reference voltage Vref and timings of the output changes, thereby estimating the waveform of the noise.

A semiconductor device including a tristate buffer circuit, which includes, on an output stage, at least a first transistor (P1) for pull-up driving and a second transistor (N1) for pull-down driving, in which, when a control signal (EN) is of a value indicating an enable state, an output is set to a high level or to a low level, depending on a data signal, and in which, when the control signal is of a value indicating a disable state, the first and second transistors are turned off to set a high impedance state of the output. The semiconductor device further includes a control unit (120, P6, P7) for performing control for speeding up the transition from the on-state to the off-state of the first transistor (P1) at the time of switching the control signal (EN) from the enable state to the disable state.
摘要:
An evaporation gas intercepting system prevents the entrance of an evaporation gas leaked from a canister into a passenger compartment of a vehicle with an air conditioning system in which an outside air intake or inside air circulation is selected. An engine control unit calculates a fuel injection quantity on the basis of parameters indicating the operating condition of an engine and correction coefficients, and a feedback correction quantity for correcting the fuel injection quantity on the basis of the output signal of an air-fuel ratio detector (oxygen sensor). If an excessive quantity of the evaporation gas is supplied to the engine such that the fuel injection quantity cannot properly be corrected by the feedback correction quantity, and the engine control unit carries out an evaporation correcting operation by using an evaporation correction, an air conditioning system control unit sets the automotive air conditioning system forcibly for an inside air circulation mode to prevent the entrance of the evaporation gas bearing a fuel odor and leaked from the canister into the passenger compartment.
