A rechargeable battery (2) and a circuit substrate (3) are connected by lead plates (4, 5) and united by a primary mold (11) that is formed by filling resin therebetween, after which a secondary mold (12) is formed on the outer face by filling resin at necessary locations and a winding sheet (13) is wound around the periphery, thereby forming a battery pack.

A secondary protective element includes: a functional element; a lead plate arranged on least one of upper and lower surfaces of the functional element; and at least one bending section arranged on a predetermined portion of the lead plate.

A secondary battery comprises a bare cell including an electrode assembly composed of positive and negative electrodes and a separator, a can acting as a container for containing the electrode assembly and an electrolyte, and a cap assembly having a cap plate for covering the open upper end of the can and a lead plate coupled to a part of the cap plate, wherein an electrolyte injection hole is positioned on a side of the cap plate. The lead plate has a bottom portion which covers the electrolyte injection hole and at least a part of which is coupled to a surface of the cap plate. Additionally, a part of the lead plate, which corresponds to the electrolyte injection hole of the bottom portion, is removed to form a hole so that a cap which seals the electrolyte injection hole is exposed.

A mower attachment comprising an attachment housing and a plurality of blade assemblies. The attachment housing includes an upper surface and front and rear baffles extending downwardly from the upper surface, the front and rear baffles shaped to define a plurality of blade chambers therebetween. The plurality of blade assemblies are positioned within the plurality of blade chambers. A leading plate is operatively connected to the housing and extends away from the plurality of blade chambers. The leading plate includes a plurality of apertures on a top side thereof.

A billboard or other large display for displaying information has a billboard frame, an artwork layer, and either a plurality of columns of LED light plates or vertical strips of LED lights. The LED plates are small backlight panels formed in an array covering large areas suitable for standard billboards. The LED plates are secured to one another to hang from the billboard frame in separate columns. The columns are situated between the artwork layer and the billboard frame to provide a backlight for the artwork layer. The artwork layer can include two or more layers such that different artwork is displayed depending on the ambient lighting conditions as well as the backlight operation. The LEDs are preferably controlled by a controller to provide desired backlight conditions as well as to display content.

The invention discloses a method for removing sulfate solution chloride ions through electric absorption of three dimensional electrodes. The method comprises the steps that an anode region is filled with activated carbon as a third electrode, anodic polarization is performed, a titanium plate is used as an anode, a lead plate is used as a cathode, and an insulation membrane is used for isolating a cathode region from the anode region; the pH value of chlorine-containing wastewater with the concentration of chlorine ions being 800-1200 mg / L is adjusted to 1-4, the wastewater is introduced into the three-dimensional electrodes, and the anodic polarization potential is controlled to be larger than 1.0 V and smaller than or equal to 1.5 V, a peristaltic pump is used for guiding wastewater inside an external circulating pond into a reactor through a peristaltic pump, the wastewater obtained after the reaction flows back to the circulating pond, and circulating water meeting the standard (300 mg / L) of the circulating cooling water quality is obtained after circulation is performed for a period of time. According to the method, equipment is simple, operation is convenient, particularly, the effect of treating sulfate solution high-concentration chlorine-containing wastewater is good, the cost of activated carbon is low, energy consumption is low, and industrial production and application are promoted.

The invention discloses a tracer flow polymer injection profile well logging instrument, a tracer, a tracer makeup device and a well logging method. The well logging instrument comprises a remote-sensing nipple equipped with a collar locator CCL, a tracer sprayer equipped with a continuously rotating motor, and a gamma-ray probe equipped with a near probe and a far probe. The tracer makeup device comprises a control box and a makeup box. The makeup box, which is equipped with a lead glass screen and a lead plate, is arranged on the control box. The bottom of the makeup box is equipped with a guide rail and a protection plate. A stirrer and a funnel are arranged above the guide rail. The stirrer is connected with a weight dropper. 4.5 to 3.5 weight shares of solid polymer, 4.5 to 3.5 weight shares of guar gum, and 2.5 to 1.5 weight shares of amylum are mixed with a tracer suspension to make a liquid with the concentration of 2000mg per litter, and then the liquid together with the 0.5mCi 131Ba micro-spherical tracer to make a suspension. The tracer flow well logging method and the isotope tracer water-injection profile well logging method are used for the well logging. The tracer suspension is first evenly sprayed continuously and then is sprayed in a spotting way. The tracer suspension of the invention is even, and is provided with a low lower limit and a high precision. Moreover, the well logging instrument of the invention is low in the cost.

Disclosed is a waste heat recovery system with a cleaning apparatus, which can effectively recover waste heat and easily clean the system, thereby increasing heat exchange efficiency and making its maintenance easy. The waste heat recovery system includes: a tank; heat exchange pipes connected with one another in the form of a ‘S’ shape in multiple steps inside the tank and having city water flow pipes bound up into a bundle; circulation leading plates mounted between the heat exchange pipes for inducing a flow of waste water; movable nozzles mounted on the circulation leading plates and connected with a high pressure water pipe for spraying high pressure water onto the surface of the heat exchange pipe or having a brush for cleaning the surface of the heat exchange pipe; a nozzle driving part for driving the movable nozzle by means of a driving motor; and waste water inlet and outlet for flowing hot waste water from the upper portion to the lower portion of the tank and city water inlet and outlet for flowing city water from the lower portion to the upper portion of the tank.
