摘要： A vehicle operator protection system includes an actuating device, a battery for supplying the actuating device with electric power, and a backup capacitor charged by the battery and supplying power to the actuating device when the battery becomes inoperable. It further includes a switch for cutting off the power supply from the battery and a determining circuit for detecting a discharging condition of the backup capacitor after it has been cut off from the power supply with the switch to determine the existence of an abnormality in the backup capacitor and the actuating device. Through the detection of the discharging condition of the backup capacitor, determination of the existence of an abnormality, based on the intended function of the backup capacitor, can be achieved.

摘要： A circuit for controlling the actuation of a vehicle air bag system includes a two terminal electrically actuated ignition element connectable to a drive voltage line through a first transistor and to a circuit ground through another transistor. The voltage source includes the vehicle battery and a capacitor that is charged by the vehicle battery and which supplies operating power in the event the vehicle battery is removed from the circuit, for example, as a consequence of a collision. The transistors are normally biased to a non-conducting state sufficient to isolate the ignition element from the drive voltage source and circuit ground. Vehicle acceleration is sensed by an acceleration sensor which, in the event of a collision, biases both transistors into conduction to effectively connect the two terminals of the ignition element to the drive voltage line and to ground to actuate the vehicle air bag. During normal operation, a bias circuit controls one of the transistors to provide a minute current flow that is used to sense fault conditions and illuminate an alarm lamp. During a collision, the acceleration sensing circuit re-configures the bias circuit to drive both transistors into conduction. A low-voltage circuit senses the drive voltage and controls the bias to the one transistor to inhibit the minute current flow to conserve power during low-voltage conditions.

摘要： A refrigeration system for an automotive air conditioner includes an evaporator and a variable displacement refrigerant compressor adapted to be driven by an automotive engine. In order to control the refrigeration system, detectors are provided to detect a condition related to the cooling operation of the evaporator, such as air temperature just downstream of the evaporator or the refrigerant pressure, and to detect air temperature in the occupant compartment of the automobile, ambient air temperature outside the automobile or intake air temperature upstream of the evaporator. Signals emitted by the detectors are utilized to control the compressor operation such that the displacement capacity of the compressor is varied stepwise and the compressor is operated intermittently whereby the load on the engine is reduced and the frosting of the evaporator is prevented.

摘要： A variable valve timing device, with a simplified structure and reduced cost, reliably and continuously changes a rotational phase of a camshaft relative to a crankshaft, and can change not only valve opening and closing timing but also valve opening and closing times. A first motion gear to which a rotary power is transmitted from a crankshaft and a second motion gear which transmits rotary power to a camshaft are independently rotatably arranged on a first shaft. A first variable gear meshed with the first motion gear and a second variable gear meshed with the second motion gear are integrally rotatably arranged on a second shaft spaced apart from and in parallel with the first shaft. An adjuster holds the second shaft and rotates the second shaft around the first shaft. The first and second variable gears have different numbers of teeth.

摘要： An automotive air conditioner has an air duct in which a refrigerant evaporator of a refrigeration cycle is disposed in fluid-flow communication with a variable capacity refrigerant compressor driven by an automotive engine and provided with compressor displacement varying members. A blower is provided to cause air to flow through the evaporator and through the duct into the passenger compartment. A sensor is provided to detect a condition representing the cooling operation of the evaporator, such as the air temperature downstream of the evaporator, surface temperature thereof or the pressure of the refrigerant at the evaporator. An electric controlling circuit is operative in response to signals from the sensor to actuate a servo motor which in turn drives the compressor displacement varying members whereby the capacity of the compressor is varied in accordance with the condition detected by the sensor.
