In a torque sensor having lead pins connected to a wire harness, the wire harness includes: a plurality of lead wires; a plurality of connection terminals each having a sleeve mounted around each of the lead pins and a connection portion extended from an outer periphery of the sleeve to be connected with one end of the lead wire; and an electrically insulating terminal holder for holding the plural connection terminals. The terminal holder includes: a sleeve holder portion for holding the sleeves in mutually spaced relation in order to prevent the sleeves from contacting each other; and a connection-portion holder portion for holding the connection portions in mutually spaced relation in order to prevent the connection portions from bending to contact each other.

A boiler recovers a soda component from pulp spent liquor and is able to prevent carry-over of unburnt char and deformation of a char bed configuration and to attain a stable combustion with low NO,generation. By regulating the combustion air supply, and feeding inert gas along a furnace side wall around the char bed, there are formed a combustion zone of reduction atmospheric field where air ratio in the surroundings of the char bed is 0.8 or less, a combustion zone of reduction atmospheric field where air ratio is 1.0 or less and unburnt components exist (including the case of a reduction atmospheric field where air ratio is 1.0 or less and unburnt components exist with the two combustion zones being combined together) and a combustion zone where combustion is completed.

A throttle valve of a motor vehicle is controlled by a control unit through an actuator. The control unit determines a desired magnitude of longitudinal acceleration in accordance with running conditions of the present vehicle and the front-running vehicle, a desired throttle opening degree in accordance with the desired magnitude of longitudinal acceleration, and a control variable in accordance with the desired throttle opening degree. The actuator is operated in accordance with the variable.

System for controlling a throttle valve in a following control system

An automatic driving system for a motor vehicle has a main actuator for operating a main throttle valve, an auxiliary actuator for operating an auxiliary throttle valve, and sensors for detecting driving conditions of a present motor vehicle and for producing driving condition signals. A failure of the automatic driving system is determined based on the driving condition signals. In response to the determined failure, the main and auxiliary actuators are operated so as to close the main and auxiliary throttle valves.

Fail-safe system of an automatic driving system for a motor vehicle

A trunk lid of a motor vehicle is closed by engagement of a striker secured to the trunk lid with a latch body of a locking mechanism secured to the trunk of the vehicle. When the trunk lid is closed, the lowering thereof to its closed position is electrically detected by a trunk lid sensor and, in response to it an electrical driving device including an electric motor, is operated to rotate a claw pivotably secured to the latch body so as to move the striker in a guide slot of the claw to a locking position of the latch body. The operation of the electric motor is transmitted to the claw to rotate the same through wire means, link mechanism or gear arrangement.

A system comprises rough correcting operation for roughly correcting the ignition timing to a desired ignition timing, fine correcting operation for finely correcting the roughly corrected ignition timing, and acceleration correcting operation for correcting the roughly corrected ignition timing at the acceleration of the engine.

System for controlling the ignition timing of an internal combustion

A system and method for deciding the ignition timing at the acceleration of an engine and the steady state. The system has an acceleration ignition timing correction subroutine and a steady state ignition timing correction subroutine. In the acceleration ignition timing subroutine, a basic ignition timing obtained in the steady state ignition timing correction subroutine is corrected by a quantity read from a table so as to sufficiently advance the ignition timing for the acceleration and the steady state.

A knock sensor is provided on a selected cylinder which is most liable for engine knocking to occur. The ignition timing is corrected in accordance with the occurence of knock in the selected cylinder. The corrected ignition timing is stored in a table for operating all cylinders of the engine.

A first maximum ignition timing table storing a plurality of degrees of ignition timing each producing a maximum engine torque dependent on engine speed with low-octane gasoline without occurring the knock, and a second maximum ignition timing table storing a plurality of degrees of ignition timing each producing a maximum engine torque dependent on engine speed with high-octane gasoline without occurring the knock are provided. A first ignition timing and a second ignition timing are provided from the first and second maximum ignition timing tables in accordance with engine speed, and a correcting quantity having a value within the difference between the first and second ignition timings is obtained. An ignition timing is obtained by using the correcting quantity.

A system for quickly converging the ignition timing to a desired timing when a large deviation occurred in the ignition timing. Change of engine operating conditions which will cause such a deviation is detected by a large engine knock to produce a correction signal. In response to the correction signal, an ignition timing correcting quantity is increased so as to quickly correct the ignition timing.

A system for quickly converging the ignition timing to a desired timing. The number of inversions of correcting direction, such as from advancing to retarding, is counted up. The quantity of correction at a time is gradually reduced as the number increases.

A system is provided for quickly converging the ignition timing to a desired timing when a large deviation occurs in ignition timing. The system comprises rough correcting operation for roughly correcting the ignition timing to a desired ignition timing and for producing a completion signal when the correction reaches a complete state, fine correcting operation responsive to the completion signal for finely correcting the ignition timing by a correcting quantity. When the correcting quantity becomes larger than a predetermined value, the rough correcting operation restarts, so that a large deviation of the ignition timing is quickly deviated.

A control system has a circuit for deciding ignition timing in accordance with driving condition of a motor vehicle, a sensor for detecting the magnitude of the acceleration of an engine, and a knock sensor for detecting knock of the engine. When the knock is detected, the ignition timing decided by the circuit is corrected in accordance with the magnitude of the knock, with the magnitude of the acceleration, and with the driving condition.
