    • In order to effectively perform on/off control for an air-conditioning system carried on an automobile during idling operation of the automobile, if a state, in which a difference between a target idling number of revolution and a net idling number of revolution is larger than a preset difference value, is continued for a preset period of time, then an electromagnetic clutch is disconnected, and a compressor is allowed to be in an operation stop state. After that, if the difference is smaller than the preset difference value, and a state, in which the difference is smaller than the preset difference value, is continued for a preset period of time, then the electromagnetic clutch is connected, and the compressor is restored to be in an operating state. By doing so, it is possible to previously avoid the occurrence of vibration of the vehicle body due to vibration of the engine, and the occurrence of booming noise in the vehicle's cabin caused by the vibration. The air-conditioning system is automatically restored to be in the operating state when it is judged that the state of the engine is restored. Therefore, the convenience of use of the air-conditioning system is improved.
    • 为了在空转怠速运转中对汽车上的空调系统进行有效的开/关控制,如果目标怠速转数和净怠速转数之间的差较大的状态 比预设差值继续预定的时间段,则断开电磁离合器,并且允许压缩机处于操作停止状态。 之后,如果差值小于预设差值,并且将差异小于预设差值的状态持续预定时间段,则电磁离合器连接,压缩机 恢复到运行状态。 通过这样做,可以预先避免由于发动机的振动引起的车身振动的发生,以及由振动引起的车厢内出现的蓬勃发展的噪音。 当判断发动机的状态恢复时,空调系统自动恢复到运转状态。 因此,提高了空调系统的使用方便性。

    • A fuel supply control system for an internal combustion engine installed in a vehicle has an ECU which controls the amount of fuel to be supplied to the engine according to the rotational speed of the engine detected by a rotational speed sensor and load on the engine detected by a load sensor. The supply of fuel to the engine is interrupted when the detected rotational speed of the engine exceeds a first predetermined value, and the supply of fuel to the engine is resumed when the detected rotational speed of the engine drops below a second predetermined value which is lower than the first predetermined value. When the supply of fuel to the engine is resumed, the air-fuel ratio of a mixture supplied to the engine is leaned by decreasing the amount of fuel to be supplied to the engine, depending on at least one of the detected load on the engine and the detected traveling speed of the vehicle.

    • A control system for an internal combustion engine controls a fuel injection amount based on operating conditions of the engine and an evaporative fuel concentration-dependent correction coefficient. The control system includes a purge control valve arranged in a purging passage connecting a canister for temporarily storing evaporative fuel generated from a fuel tank and an intake passage. This coefficient is held to a predetermined value for a predetermined time period after purging is permitted, and to another for a predetermined time period after purging is inhibited. In another aspect, the purge control valve is controlled based on operating conditions of the engine and a purging flow rate correction coefficient. This coefficient is held when purging is inhibited, and is progressively set to a larger value depending on the evaporative fuel-dependent correction coefficient, after purging is permitted. In another aspect, when a vehicle on which the engine is installed is started, the purge control valve is controlled based on a special purging control amount which is progressively increased based on a parameter related to a standing start of the vehicle. In another aspect, the operation of the purge control valve is inhibited for a predetermined time period dependent on a temperature of the engine, after the start of the engine. In yet another aspect, the flow rate of purged fuel vapor is corrected in accordance with the amount of exhaust gas recirculation.

    • An optical tape apparatus having improved focus and tracking control. An optical head records, reproduces, or rewrites data on an optical tape by helically scanning the tape with a laser beam. A guide plate is disposed between the optical head and the tape to prevent the beam from becoming unfocused due to fluctuation of the tape cuased by an air film between the optical head and the tape. The optical head contains a semiconductor laser and an optical system exhibiting chromatic aberration for directing the laser beam onto the tape. The optical system includes a condenser lens for focusing the beam onto the tape. Fine focus control is achieved by changing the wavelength of the laser beam by directing part of the beam reflected from the tape back to the laser, thereby changing the focal point of the beam by virtue of the chromatic aberration of the optical system. Coarse focus control is achieved by mounting the condenser lens on a piezoelectric actuator which moves the consenser lens to focus the beam onto the tape. A recording head for recording timing marks and tracking signals on the tape is disposed in advance of the optical head. A reading head reads the timing marks and the optical head reads the tracking signals. The timing marks and tracking signals are used to control the operation of the apparatus such that the tape is transported with a constant speed and data on diagonal signal tracks on the tape is accurately recorded, reproduced, or rewritten.

    • An intake secondary air supply system for adding air to the intake of an internal combustion engine under certain sensed conditions, such as an excessively rich air-fuel ratio detected by an oxygen sensor in the exhaust system, wherein two separate secondary air supply passages are provided and separately controlled by vacuum responsive valves. One of such valves is controlled to open and close over a period of time to provide a changing supply of secondary air while the other valve is connected through a solenoid operated valve to the engine intake to provide an immmediate opening or closing of that secondary air supply. Vacuum controls responsive to engine operating condition serve to operate the vacuum responsive valves although in one embodiment one of such valves is operated by a constant regulated vacuum.
