In an index signal generator for generating an index signal for use in a direct-drive motor having a rotation axis and comprising a stator and a rotor, a particular at least one of M magnetized elements is used as an index detection magnet having magnetic force which is different from those in remaining ones of the M magnetized elements. Wound around one of a specific one of particular three cores in the stator, an index detection coil detects variations of the magnetic force generated by the ring-shaped permanent magnet to produce a detected signal. On the basis of the detected signal, the index signal is generated.

The receiver apparatus includes a receiver which receives the transmitted digital information, a demodulator which demodulates the digital information received by the receiver, an error detector which detects an error of a digital information demodulated by the demodulator by use of a parity signal, a first expander which bit-expands video information among digital information error detected by the error detector corresponding to the first compression system and a second expander which bit-expands audio information among digital information error detected by the error detector corresponding to the second compression system.
摘要:
A driving cam includes a circular surface portion at an outer cam surface thereof. When an engine is turned off, the circular surface portion is brought into contact with a roller. Thereby, even if a load is applied to the control axis member, no rotational force is circumferentially applied to the driving cam. As the result, even if a driving force is not applied from a motor to the driving cam, a rotational angle of the driving cam and an axial position of the control axis member are kept constant. Therefore, it is possible to keep the driving cam and the control axis member at a constant position without adding a complicated mechanism.

An engine mount which is capable of changing its vibration transmission characteristics with a simple structure using an inexpensive actuator is provided. A partition is inserted to a side member to which a mount rubber (rubber vibration isolator) of the engine mount is spliced to close a space between the mount rubber and to create an air chamber. An air duct pipe which communicates with the air chamber is connected to the side member and is connected to a VSV (vacuum switching valve) via a connection pipe. The VSV is controlled to ON/OFF states based on a driving voltage Vout from an ECU which corresponds to explosive vibrations of the engine to switch pressure within the air chamber to negative pressure of a vacuum tank in which negative pressure of an intake manifold is accumulated or to atmospheric pressure, interlocking with the vibration of the engine. Thereby, the vibration transmission characteristics of the engine mount may be adequately changed and the vehicular vibration may be reduced significantly.

A fuel injection apparatus for a diesel engine has a fuel injection pump for feeding fuel under pressure and fuel injection nozzles provided in the engine to inject fuel fed from the injection pump. A pressure sensor for detecting fuel pressure is provided in a midway in a fuel line connecting the injection pump to the injection nozzles. An electronic control unit (ECU) computes the frequency of the fuel pressure based on a detected value from the pressure sensor immediately after fuel is injected from the injection nozzles. The ECU then computes a fuel bulk modulus based on the result of the computation of the frequency of the fuel pressure. Based on the computed bulk modulus, the ECU computes a fuel injection start and end time. Further, the ECU adjusts an instruction value for fuel injection control based on the result of the computation of injection start and end, and controls the injection pump based on the adjusted instruction value.
