    摘要: A VVA apparatus includes a control shaft arranged rotatable in accordance with the engine operating conditions, an alteration mechanism for changing a lift amount and an operating angle of an engine valve in accordance with rotation of the control shaft, and a drive mechanism for rotating the control shaft and including an electric motor and a reduction mechanism. The reduction mechanism has a reduction ratio set to be larger when the valve is under small lift-amount and operating-angle control than when the valve is under large lift-amount and operating-angle control.

    摘要: An object of the invention is to provide a receiving circuit where the quality of reception can be prevented from deteriorating when the gain changes, so that the good quality of the received signal can be preserved, as well as a receiving apparatus and a transmitting/receiving apparatus using the receiving circuit. In the configuration of the invention, a switch (113) is converted to a short state in response to a change in the gain of a variable gain amplifier (107) by means of a gain control apparatus 112, and thereby, the output terminal of a high pass filter (111) is fixed at a reference voltage and the cutoff frequency of a low pass filter (108) is increased. As a result, the period during which the DC voltage has transient response properties in the low pass filter (108) can be shortened, and this transient response prevented from passing through the high pass filter (111).

    摘要: In a compression ignition engine employing a variable valve actuation mechanism variably adjusting an intake valve characteristic including at least one of an intake valve lift and an intake valve closure timing, a control system operates to temporarily lower an effective compression ratio of the engine by controlling the intake valve characteristic during a cranking period of cold starting operation. At a point of time when a predetermined cranking speed threshold value has been reached owing to a cranking speed rise, the effective compression ratio is risen by controlling the intake valve characteristic. After combustion of the engine has been stabilized, the intake valve characteristic is brought closer to a desired value determined based on engine operating conditions by way of closed-loop control.

    摘要: A digital communication device includes: a modulator having encoding means for converting two-dimensional digital information signal into a three-dimensional signal and phase modulation means for modifying the carrier phase in according to the three-dimensional signal; and a demodulator having phase demodulation means for detecting information on the three-dimensional signal from the received phase-modulated wave and demodulation means for deciding the two-dimensional digital information from the information on the three-dimensional signal. The digital communication device has a bit error ratio and an occupied radio band width equivalent to a digital communication device using the conventional QPSK or π/4 shift QPSK and the error correction method and greatly improves the amplitude fluctuation. Moreover, the digital communication device can transmit a signal with a narrower occupied frequency band width while maintaining the same constant envelope characteristic as the GMSK using the conventional error correction code.
