This invention provides a switchable conductive slip ring device with extended lifespan, comprising a housing, a conductive ring, a switchable control assembly, and a sliding contact. The conductive ring is sleeved on a first positioning shaft and rotates around it; the sliding contact is rotatably connected to a second positioning shaft, the two positioning shafts being parallel and offset. The sliding contact is located outside the conductive ring and extends radially along the second positioning shaft to form a first contact and a second contact. The switchable control assembly includes a compression spring and a top block, the top block having an inclined surface facing the conductive ring and slidingly engaging with the sliding contact. The sliding contact has two operating states: in the first state, the compression spring causes the first contact to abut against the conductive ring, and the second contact separates; in the second state, the top block moves, driving the sliding contact to rotate, the second contact abuts against the conductive ring, and the first contact separates. This application has the advantage of enabling long-term continuous and stable operation with only a single rapid switch, thus extending the lifespan of the conductive slip ring.

A light source includes a chamber, a first electrode assembly, and a second electrode. The first electrode assembly includes a first electrode, a rod, and a tip portion. The rod extends longitudinally through a portion of the first electrode. The tip portion is coupled to the rod and includes a first discharge surface. The second electrode has a second discharge surface spaced apart from the first discharge surface by a discharge gap. The rod adjusts a position of the tip portion to maintain the discharge gap. The first and second electrodes excite a gas discharge medium of the chamber to generate a light beam. Advantageously, the system maintains the discharge gap over time, maintains flow between the discharge gap, adjusts a position of the first discharge surface based on one or more parameters of the light source, reduces errors in the light beam, and increases lifetime of the light source.

This element (I) comprises a plate (1) made of a piezoelectric material which has, on the acoustic wave emission face, a first electrode (2) cooperating with a single connecting wire (4) and, on the opposite face (12), a second electrode (3) cooperating with two electrical connecting wires (5, 6) fixed on extensions (32, 34) of this second electrode. According to the invention, each wire (5, 6), cooperating with the second electrode (3) is such that the total geometric cross-section (π(D5)2 / 4) of the second wire is between 0.15 and 0.40 square millimeters (mm2), the diameter (d5) of each strand of this wire is between 0.035 and 0.060 millimeters (mm), and the total number of strands (n) is between 100 and 160. This combination of values ​​gives sufficient flexibility to the wire, thus reducing the mechanical stresses exerted at the junction between the strands and the brazing pad.This flexibility also allows the use of wires with small radial dimensions, ensuring use in an environment that promotes miniaturization.

An object is to extend a replacement lifetime of a cryocooler and reduce a replacement frequency of the cryocooler, thereby improving an operating rate of an MRI apparatus.A cold head lifetime extension mode is executed. In the cold head lifetime extension mode, a displacer of a cryocooler is driven at a constant frequency that is lower than a predetermined upper limit frequency regardless of a temperature of a superconducting coil, and a drive frequency of a compressor drive unit adjusted by an inverter for a compressor is controlled in accordance with the temperature of the superconducting coil.

The invention relates to the technical field of data storage, and discloses a solid state disk service life prolonging method based on a wear leveling algorithm, and the method comprises the following steps: collecting physical block wear state data and logic block access thermodynamic data of a solid state disk; performing solid state disk global health degree evaluation processing based on the physical block wear state data and the logic block access thermodynamic data to generate solid state disk global health degree feature data; when wear balancing is carried out on the solid state disk to prolong the service life, logic block access thermodynamic data are collected in real time, logic data cold and hot partitions are dynamically updated, sudden changes of written loads and dynamic migration of data access locality can be perceived and adapted, and therefore a balancing strategy is adjusted in time when load characteristics change, and the service life of the solid state disk is prolonged. Concentrated abrasion of the specific physical block caused by sudden writing is relieved, and timeliness and effectiveness of the service life prolonging effect are improved.

To extend the life of an optical element in an EUV lithography system.SOLUTION: Degradation of the reflectivity of one or more reflective optical elements in a system (SO) for generating EUV radiation is reduced by controlling the introduction of gas into a vacuum chamber (26) housing the optical elements. The gas may be added to the flow of another gas, such as hydrogen, or may be alternated with the introduction of hydrogen radicals.SELECTED DRAWING: Figure 5

A method for extending the storage lifetime of a rechargeable battery located in a device is disclosed. The battery lifetime extension method includes providing a device that derives its power from a rechargeable battery. When the device is powered off by a user, a computer implemented program utilized by the device automatically powers up the device into a lower power mode upon expiration of a variable duration timer monitored by the computing unit that continuously repeats according to a programed duration cycle. The computer implemented program then evaluates a state of charge of the rechargeable battery, determines whether the state of charge of the rechargeable battery is above or below a variable programed threshold, and causes the rechargeable battery to remain in a low power state until a charge is applied to the rechargeable battery.
