摘要:
A water closet with a topical body washing mechanism including a water warmer mounted on the water closet and a spout pipe having a nozzle at the distal end therof for spouting warm water from the water warmer. The spout pipe is movable to and from an inoperative rest position within a bowl of the water closet, a second position advanced over the bowl to direct a jet of warm water toward the anus of the user and a third position further advanced over the bowl to direct a jet of warm water in a direction suitable for use as a bidet. An operating lever has a cam mounted on its rotational axis, the cam being contoured correspondingly to the second and third positions of the spout pipe to actuate a switch thereby starting a motor of a pump which sends forward warm water from the water warmer to the spouting nozzle. The electric circuit which includes the aforementioned motor and switch has in series a switching element and a delay circuit. When the motor switch is closed by the cam, the switching element is actuated starting the emission of water jets with a delay. Therefore, gushing of water at the second position is prevented when the spout pipe is shifted quickly from the first to the third position.

A motor assisted steering apparatus has its wheels oriented with respect to a car body in response to a combination of a steering force which is supplied by a manual operation and a driving force developed by an electric motor which is energized in accordance with the steering force. The existence of an abnormality is annunciated when the relationship between the manual steering force and the operational condition of the motor deviates from a predetermined relationship. For example, the existence of an abnormality is annunciated when the motor is energized even though a steering wheel is not substantially operated, when the motor is energized for rotation in a direction which causes the wheels to be turned to the left even though the steering wheel is turned to the right or vice versa. The existence of such abnormality is detected by monitoring the manual steering force and the operational condition of the motor, without requiring any addition of sensors which have no direct connection with the operation of the apparatus.

A torque detector is provided, which functions in such a manner that as torque is applied between an input shaft and an output shaft, an angular displacement is produced between the input shaft and the output shaft, this angular displacement is converted into an axial displacement by means of a torque-axial displacement converting mechanism to bend a cantilever fixed between a housing and the torque-axial displacement converting mechanism, by means of a strain gage attached to the cantilever the deformation of the cantilever is converted into a change of electric resistance, and by causing a current to flow through the strain gage the torque applied between the input shaft and the output shaft is converted into a voltage.

A driving system of a bridge circuit for driving an inductance load turns OFF one of switching elements on either an upper arm connected to a power supply or a lower arm connected to a ground and turns ON the other one of the switching elements on the same arm when a pulse width modulation signal is OFF when a phase difference occurs between an electric current of a control signal with a sine wave and a voltage and when a polarity of the electric current differs from a polarity of the voltage, wherein the electric current is circulated via the other one of the switching elements, the flywheel diode connected to the one of the switching elements, and the inductance load.

A fail-safe arrangement for an electrical power steering system is directed to providing a control arrangement for a power steering motor which will prevent abnormal operation from having adverse impact. The control system detects the welding or sticking together of closed relay contacs and functions to prevent such a situation by monitoring the motor terminal voltage so as to cut off power above a predetermined value regardless of position of the relay contacts.

An active vibration insulator includes an electromagnetic actuator, a cyclic-control-signals output device, and an electromagnetic-actuator driver. The electromagnetic-actuator driver includes an asymmetric half-bridge circuit, and an actuating-signals output device. The actuating-signal output device outputs a signal for turning on one of a high-side switch and a low-side switch of the asymmetric half-bridge circuit, and outputs a pulse-width-modulated actuating signal for actuating the other one of them by means of pulse-width modulation based on the cyclic control signals, which the cyclic-control-signals output device outputs, or outputs a pulse-width-modulated actuating signal for actuating both of them by means of pulse-width modulation when the cyclic control signals are positive. Moreover, the actuating-signal output device outputs a signal for turning off one of them, and outputs a pulse-width-modulated actuating signal for actuating the other one of them by means of pulse-width modulation when the cyclic control signals are negative.

A method of generating action control data includes an actuator as a control object, a detector for detecting an actual measured data of an action signal in the actuator, and a data map including control data which can perform a preferable condition of control by activating the actuator. The method of generating action control data for activating the actuator in accordance with a driving condition appropriate at a time of controlling on the basis of an appropriate control data selected from the data map includes the steps of calculating a deviation between the appropriate control data and an actual measured data, modifying the appropriate control data on the basis of calculated deviation, and generating the modified appropriate control data as the action control data.
摘要:
A motor driven power steering apparatus includes a steering mechanism having a torque detector for detecting torque applied to the mechanism through a steering wheel. An electric motor is connected to the steering mechanism through an electromagnetic clutch. The current in the electric motor is monitored and if it becomes excessive, a control circuit is activated to deactivate the clutch. The electric motor is disconnected from the steering mechanism at the time the engine of the vehicle is starting and at other times during operation of the vehicle to determine if excess current flows through the motor which would be indicative of a malfunction of the electric motor.

摘要:
An active vibration insulator includes an electromagnetic actuator, a controller, and a bad-roads processor. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The controller carries out vibrating-forces generation control. In the vibrating-forces generation control, the electric-current supplies are made variable so as to actively inhibit vibrations generated by an on-vehicle vibration generating source of a vehicle from transmitting to a specific part of the vehicle based on cyclic pulsating signals output from the on-vehicle vibration generating source. Thus, the controller lets the electromagnetic actuator generate the vibrating forces. The bad-roads processor stops the vibrating-forces generation control effected by the controller when the vehicle travels on bad roads.
