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 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.

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.

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.

One thermally insulated box, meeting the specified requirements from the group of thermally insulated boxes, and a matching cooling unit are transported to the installation site of the cooling storage unit. The thermally insulated box and the cooling unit are combined at the installation site to constitute the cooling storage unit.

An object of the present invention is to provide an abnormal vibration detection unit which is capable of stopping a wind turbine generator in a case of detecting excessive vibration that poses danger and is designed suitably for the failure detection. The abnormal vibration detection unit comprises first and second acceleration detectors, a calculation device which receives a first analog output signal that is outputted from the first acceleration detector, a filtering relay which receives a second analog output signal that is outputted from the second acceleration detector, and a safety system which performs an emergency stop of the wind turbine generator in accordance with a state of an output terminal of the filtering relay. The filtering relay comprises a filter circuit part that performs filtering process to extract a predetermined frequency component from the second analog output signal. The calculation device generates a predicted value of the output signal of the filter circuit part by performing digital calculation of the first analog output signals, and detects a failure of the first acceleration detector, the second acceleration detector, or the filter circuit part by comparing the predicted value of the output signal of the filter circuit part with a measured value of the output signal of the filter circuit part received from the filtering relay.

An arrangement for clock control in a device receiving a clock from an external source includes switching means (101) for switching an external clock through to the device as an internal clock, and clock request generation means (102, 103), adapted to switch clock signal through to the external clock controller as requests for suppressing and restarting the external clock. Control means (104) are provided in the form of a state machine to control the generation of the internal clock through the switching means, and to control the clock request generation means in accordance with a predetermined state of two signals, one generated internally by the device, the other by the external clock controller (20).

An overhead traveling vehicle and the local carriage each includes a hoist and travel directly over load ports. The track for the local carriage includes a pair of rails directly under a track for the overhead traveling vehicle, and articles vertically pass between the pair of rails using the hoist of the overhead traveling vehicle. A sensor detects an article that is horizontally swinging in a direction perpendicular or substantially perpendicular to the lengthwise direction of the track for the local carriage in the horizontal plane and is provided at least at a position that is under the track for the local carriage and outside of the raising and lowering path of an article that is not horizontally swinging. The overhead traveling vehicle and the local carriage stop the raising and lowering of the hoists when the sensor detects an article that is horizontally swinging.
