Thunder-lightening induced solid-phase arc-extinguishing lightning arrester

The invention discloses a thunder-lightening induced solid-phase arc-extinguishing lightning arrester. The thunder-lightening induced solid-phase arc-extinguishing lightning arrester mainly consists of a lightning arrester shell, an arc-extinguishing rotary table, an electric conduction metal plate, a starting rod, a clamping rod, an induction coil, an arc-extinguishing barrel and a counting pointer; the arc-extinguishing rotary table is arranged inside the lightning arrester shell, and a flat spiral spring for pushing the arc-extinguishing rotary table to rotate is arranged at the central position of the arc-extinguishing rotary table; the electric conduction metal plate is arranged at the upper part of the arc-extinguishing rotary table; the arc-extinguishing rotary table is provided with a plurality of arc-extinguishing gas pills in the peripheral direction; one side of each arc-extinguishing gas pill is provided with a trigger electrode and a groove respectively, one end of each trigger electrode is connected with one of trigger ends of the corresponding arc-extinguishing gas pill through a lead, and the other ends of the trigger electrodes extend out of the edge of the arc-extinguishing rotary table; and the other of the trigger ends of the corresponding arc-extinguishing gas pill is connected with the electric conduction metal plate through a lead. The thunder-lightening induced solid-phase arc-extinguishing lightning arrester is simple in structure, reasonable in design, high in arc-extinguishing ability and stable and reliable to work, and the arc-extinguishing gas pills are changed quickly and conveniently.

Method for operating a safety device for a handling device, safety device for a handling device, and handling device

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.

Refrigerating storage cabinet

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.

Abnormal vibration detection unit for wind turbine generator

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.

Brake system for a vehicle

The invention relates to a brake system (1) for a vehicle. Said brake system (1) has a parking brake function (2) for immobilizing said vehicle. Said parking brake function (2) in turn has a parking brake control function (3) for the electronic control of the immobilization. Furthermore, an electronic and / or electropneumatic device (4, 6, 14, 26, 34, 162, 179, 186, 208, 210) of the brake system (1), particularly an air treatment device (26, 162, 179, 186, 208), an axle modulator (34), a trailer control valve, a controller of an electronic brake system, or a driving dynamics regulating unit (210), and / or an electropneumatic device of the vehicle, particularly an air treatment device or an air suspension device, have a second function (5). Said second function (5) differs from the parking brake function (2). According to the invention, in addition to the second function (5) said device (4, 6, 14, 26, 34, 162, 179, 186, 208, 210) has the parking brake control function (3).

Scanning signal line driving circuit, display device provided therewith, and scanning signal line driving method

The purpose of this invention is to provide a scanning signal line driving circuit with increased reliability of switching elements while reducing power consumption. In the vertical blanking interval, an end signal (ED) changes from the low level to the high level. The potential of the 1st through (m-1)st stage first nodes (N1) of cascade-connected m-stage bistable circuits contained in a shift register of the scanning signal line driving circuit is reliably maintained at the low level, and the potential of 1st through (m-1)st stage second nodes (N2) changes from the high level to the low level. 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.
