BEOL memory cells are described that include one or more sidewall protection layers on the memory device (including, for example, an MTJ element) deposited prior to interconnect via etching to prevent the formation of electrical shorts between layers. One embodiment uses a single layer sidewall protection sleeve that is deposited after the memory device has been patterned. The layer material is vertically etched down to expose the upper surface of the top electrode while leaving a residual layer of protective material surrounding the rest of the memory device. The material for the protection layer is selected to resist the etchant used to remove the first dielectric material from the via in the subsequent interconnect process. A second embodiment uses dual-layer sidewall protection in which the first layer covers the memory element is preferably an oxygen-free dielectric and the second layer protects the first layer during via etching.

An engine starting system includes a throttle valve, an alternator, an engine speed sensor and an electronic control unit (ECU). The ECU functionally includes an automatic engine stop controller for automatically stopping the engine by interrupting fuel injection when predefined automatic engine stop conditions are satisfied, and an automatic engine restart controller for automatically restarting the engine when predefined engine restart conditions are satisfied. The automatic engine stop controller sets the quantity of intake air at a level higher than a minimum quantity of intake air necessary for keeping the engine running, decreases the amount of electric power generated by the alternator in an early part of automatic engine stop control operation, and decreases the quantity of intake air and causes the alternator to once decrease the amount of electric power generated thereby at a point in time when the engine speed drops down to a predetermined reference engine speed, and causes the alternator to later increase the amount of electric power generated thereby.

An electric parking brake control unit of an electric parking brake apparatus has an input section for receiving signals for performing automatic activation and deactivation, but does not have a determination function and a circuit for inputting signals from various sensors, which are necessary to determine whether to start the automatic activation / deactivation control. Therefore, when used in a vehicle which does not require an automatic control function and requires only a manual control function, the electric parking brake control unit can be used solely, with no signal line connected to the input section. When used in a vehicle which requires both the automatic control function and the manual control function, the input section is connected to a second control unit that can output signals for performing automatic activation and deactivation, whereby the electric parking brake control unit operates in cooperation with the second control unit.

In a method for operating a safety device for a handling device, e.g., an industrial robot having a movable gripper device and at least one sensor device at least largely surrounding the gripper device for recognizing at least possible collisions with objects located in the motion path of the gripper device, a signal is output to a control unit upon recognizing a collision risk, resulting in a modified motion sequence of the gripper device on its motion path, which modified motion sequence is a controlled reduction in the motion velocity of the gripper device.

By providing a high-k dielectric etch stop material as an etch stop layer for patterning an interlayer dielectric material, enhanced performance and higher flexibility may be achieved since, for instance, an increased amount of highly stressed dielectric material may be positioned more closely to the respective transistors due to the reduced thickness of the high-k dielectric etch stop material.

A storing section 49 stores data of a pull down cooling characteristic indicative of a time-varying mode of reduction in a target temperature drop. For example, when this is a linear function line xp, a target internal temperature drop degree takes a constant value Ap, irrespective of an operating time. An actual temperature drop degree Sp is computed on the basis of the detected internal temperature. The computed value Sp is compared with a target value Ap read from the storing section 49. When the computed value Sp is less than the target value Ap, a rotational speed of an inverter compressor 32 is increased via an inverter circuit 55. When the computed value Sp is larger than the target value Ap, the rotational speed of the compressor 32 is decreased. The speed increases and decreases are repeated so that pull down cooling is performed along the linear line xp.

A method and a device are for activating an electric parking brake of a motor vehicle, e.g., a road motor vehicle. Initiation of a connection process is recognized for disconnecting a drive motor of the vehicle when the vehicle is parked. The electric parking brake is initially activated after the initiation of the parking step, and the drive motor is disconnected thereafter. As a result, the drive motor may be used to activate the parking brake.

When the second control module is selected, it sends a second control signal to the drive module according to the motor speed at a predetermined time before the first control module has the fault, so as to control the motor to stop working.

During normal operation in which an electric braking device is operative, when a depressing force cut-off valve is closed and communication between a master cylinder and a disk brake system of a front wheel is cut off, the front wheel is braked by a brake pad directly driven by drive force of the electric braking device. When there is an abnormality in which the electric braking device breaks down, a wheel cylinder of a drum brake system of a rear wheel is operated by brake fluid pressure generated by the master cylinder operated by a driver's braking operation. Thus, since the drum brake system having a high braking function is operated in case of abnormality, the braking force is higher than the braking force during normal operation, thereby reliably stopping the vehicle.

In the mth stage bistable circuit, the potential of the mth stage first node (N1) changes from the high level to the low level, and the potential of the mth stage second node (N2) is maintained at the low level. Further, supply of the clock signal (CKA, CKB) to the bistable circuit is stopped. Until the write period in the subsequent vertical scanning period, the potential of the first nodes (N1) and the potential of the second nodes (N2) in each stage is maintained at the low level.

A drive control circuit generates a conduction drive output responsive to a detection output of an accelerator pedal depression degree sensor and an air-intake throttle-valve opening sensor, and controls a driving switch element connected to an air-intake throttle-valve opening control motor. A monitoring control circuit drives a control circuit power supply interruption element that closes a control power supply circuit of the driving switch element, and stops control operation of the driving switch element by a conduction-inhibit output.

At the time of starting operation, a status signal determines activeness of the feed-inhibit output and conduction-inhibit output, after confirming that those outputs are normal, the inhibition is released. Thus, an engine air-take control device capable of reliably stopping the motor upon occurrence of any abnormality thereby improving safety in control is provided.
