Abstract: A power generating apparatus of renewable energy type includes a rotating shaft rotated by the renewable energy received via a blade, a hydraulic pump driven by the rotating shaft to generate pressurized oil, hydraulic motors driven by the pressurized oil, and synchronous generators connected to a grid without an intervening frequency-conversion circuit and respectively coupled to the hydraulic motors. The displacements of the hydraulic motors are adjusted independently by a motor control unit. A synchronizer supplies a command value of the displacement of each hydraulic motor to the motor control unit so that before the synchronous generators are connected to the grid, a frequency and a phase of a terminal voltage of each synchronous generator are synchronized with the grid.

Abstract: A power generating apparatus of renewable energy type includes a rotation shaft, a hydraulic pump, a hydraulic motor, a generator and a pitch drive unit. When a fault even occurs, a deviation of a state indicating an operation state from a normal state value is calculated. When the deviation is not less than a first threshold value, the stop control unit performs by means of a hard-wired circuit at least one of switching the hydraulic pump to an idle state, the hydraulic motor to an idle state, and the pitch angle toward a feathering position. When the deviation is less than the first threshold and not less than a second threshold, the stop control unit performs by software control all of switching the hydraulic pump to the idle state, the hydraulic motor to the idle state, and the pitch angle toward the feathering position.

Abstract: In a data transmission system having a data processing unit (MPU) and a communication control unit (CIM) and capable of transmitting a data to a local control unit (LCU) in a half duplex mode, the data processing unit receives the data by an interruption based on an end of data reception signal supplied from the communication control unit.

Abstract: A collective wiring system for an automobile provides a central control unit which communicates with a plurality of terminal control units each connected to one or more input or output devices, such as switches, sensors, motors and the like. The control over output devices in response to the status of input devices is performed by the central control unit on the basis of tables of data stored in memory. A scan table controls the order in which data communications are made to the terminal control units to obtain their status and provide them with control commands. A monitor table stores the current status of the terminal control units and a control table stores the control data for the terminal control units. A connection table stores the relationship between the terminal control unit for an input device and the terminal control unit for the output device to be controlled thereby. Thus, connection control between input and output devices is effected by software.

Abstract: A terminal device for a multiplexed data transmission system has a decoder matrix having plural groups of function setting inputs for selecting plural types of functions such as interface, operation modes and other. One group of the function setting inputs are preferably address designating signals which are utilized for determining the interface. The other group of the function setting inputs determines various additional functions such as, for example, enabling/disabling of fail-safe function and automatic transmission function. Selection with the aid of the matrix allows selection of a large number of functions with a small number of input signals. Utilization of the address signals to this end allows the number of terminal pins to be decreased to a minimum.
