An LCD (21) for displaying a plurality of set information items is provided for a digital camera (10). When a plurality of input keys disposed around the LCD (21) are depressed, set information which is displayed adjacent to the input key can be changed. A control portion of the digital camera (10) performs a variety of control operations of the digital camera (10) in accordance with set information. Therefore, the position of the input portion which is used when the setting of the digital camera (10) can easily be understood. Thus, the setting can be changed by performing only a simple operation.

The present invention relates to a sole element, such as an insole, for a shoe, in particular for a sports shoe, as well as to a shoe, in particular a sports shoe. A sole element for a shoe comprises a first portion and a second portion, wherein the second portion comprises a deformable material, which is adapted to generate heat by being deformed. The sole element moreover comprises a transport element adapted for selectively directing the generated heat from the second portion to the first portion.

The invention relates to a method for suppressing DC oscillation overcurrent impact when a subway energy feeder device exits, comprising the following steps: first reading the working current of the subway energy feeder device and the initial value of the maximum current change; the initial value of the maximum current change is outside the DC voltage Loop PI controller output value. 2. According to the type of working conditions when the subway energy feedback device exits, different ranges of adjustment coefficients are preset. 3. Calculate the time required for the exit of the subway energy feedback device; 4. Invert the current command at the time of exit and make a difference with the actual current, then input it to the PI+PR controller to obtain the three-phase output current modulation. 5. Control the current of the subway energy feeder device to be 0 after time passes. The three-phase output current modulation value is input to the PWM driver through the pulse modulation module, and the PWM driver controls the IGBT to make corresponding switching actions. Six devices exit. This method can greatly suppress the current peak caused by the DC oscillation when the subway energy feed device exits.

Provided are crystal forms A, B, D, E, F, G and H of valsartan disodium salt and a preparation method therefor.

Arrays that are deployable and can change their electromagnetic behavior by changing their shape are provided. The arrays can steer the beam using folding techniques and / or can achieve multiple operation states by folding the structure. An array can include a foldable substrate with antenna elements disposed thereon. In a folded state, a first plurality of unit cells is visible from above the array and can be configured to steer in a particular first direction and / or operate at a particular first frequency. In the unfolded state a second plurality of unit cells, and also possibly the first plurality of unit cells, are visible from above the array and can be configured to steer in a particular second direction and / or operate at a particular second frequency.

The invention discloses a magnetic chuck device used for recording the crack repairing states of a steel bridge. The device comprises an elastic telescopic mechanism, a slider-crank mechanism, a built-in permanent magnet, a rotary plate mechanism and a magnetic attraction base; the elastic telescopic mechanism can drive the built-in permanent magnet to rotate; the rotary plate mechanism comprisesa rotary plate, a cover board and a rotary column; the rotary plate device is arranged at the top of the magnetic base; the magnetic base comprises a center magnetizer, a copper board and an arc shell; a guide rail is arranged inside the magnetic base; and the center magnetizer is a soft magnetic material and formed by splicing two pieces, and the two pieces are spaced by a copper board which is not magnetically conductive. The need for recording the different crack repairing states in the steel bridge is simplified, the magnetic telescopic mechanism controls the direction of the built-in permanent magnet, magnetization and demagnetization of the bottom of the magnetic base are achieved, and the whole device can be attracted to the position, nearby cracks, of a steel board conveniently. The changes of visible colors of fluorescent paster are achieved by rotating the rotary column, and the different crack repairing states are recorded by color changes.
