A lithium based battery includes a cell structure group formed by stacking unit cells each including a positive electrode, a negative electrode, and a separator interposed therebetween, or formed by repeatedly folding or winding an integral body of the unit cells; a battery container for containing the cell structure group; and an electrolyte, which is poured in the battery container after the cell structure group is contained in the battery container. The outer peripheral surface of the battery container is covered with an ion impermeable and extensible high polymer sheet having a tensile elongation percentage of 1% or more. With this configuration, even if there happens such a severe accident that nail pieces the battery or the battery is crashed, it is possible to prevent a large short-circuit current from flowing between the positive and negative electrodes, and hence to ensure a higher safety of the battery.

An open wrench includes a body having a mounting hole defined therethrough. Two first faces and two second faces are respective defined in the inside of the mounting hole. The two first faces and the two second faces are located along four consecutive sides of an imaginary hexagonal body. Each first face has at least two teeth defined therein. Five curved faces are defined in the inside of the mounting hole and located corresponding to five corners of the imaginary hexagonal body. Each of the first and second faces has a contact face and each contact face is connected between two adjacent curved faces. The length of each contact face is 0.5-0.65 of the length of each side of the imaginary hexagonal body.

A method of using a corner board protector to protect a corner on a palletized stack of containers. The method includes the steps of forming a one piece, corner board locator having a connection portion and an insert portion, and the corner board locator having an opening formed therethrough. Positioning the insert portion between two vertically aligned containers of the palletized stack of containers. Forming a corner board having two angled panels and a length. Inserting the two angled panels through the opening formed in the corner board locator to retain the corner board at a select height relative to the palletized stack of containers.

The present invention discloses a flip-chip semiconductor package and a chip carrier thereof. The chip carrier includes a groove formed around a chip-mounting area. The groove may be formed along a periphery of the chip-mounting area or at corners thereof. The groove is filled with a filler of low Young's modulus so as to absorb and eliminate thermal stress, thereby preventing delamination between an underfill and a flip chip mounted on the chip-mounting area.

The invention relates to a method for optimizing the domain of a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor as well as an etching method. The etching method comprises the following steps of: providing a substrate, wherein a medium layer is formed on the surface of the substrate; forming a photoresist pattern on the surface of the medium layer; etching the medium layer by using the photoresist pattern as a mask until the medium layer with partial thickness is removed; executing a charge release process to the medium layer; and etching the remaining medium layer by using the photoresist pattern as the mask. The etching method of the invention can effectively protect the corners of the etched medium. The method for optimizing the domain of the CMOS image sensor can improve the packing factor of the CMOS image sensor and effectively improve the image quality of the CMOS image sensor.

The invention discloses a plastic building form. The plastic building form comprises a horizontal rectangular board (1). Reinforcing ribs (2) are connected into the rectangular board which is hollow and divide the rectangular board into a structure provided with at least two square longitudinal-section cavities. The rectangular board is provided with at least one downward hollow support leg (4) with square longitudinal section. The invention further discloses a manufacturing method of the plastic building form. The manufacturing method of the plastic building form includes the steps of firstly, preparing materials; secondly, blending; thirdly, extruding for forming; and fourthly, performing tractive cutting. The rectangular board is the mechanism with cavities and hollow support legs, the section of each of the cavities and the hollow support legs is in the square structure, and accordingly the weight of the plastic building form is reduced while the plastic building form is easy to form, process and produce. The manufacturing method is easy to operate, low in cost and high in efficiency. Precision in controlling material formulation, time and temperature is high. Products manufactured by the manufacturing method are solid and durable.

The invention relates to the field of doorframe profiles and discloses a method for welding a doorframe profile. The method comprises the following steps of: firstly, cold-pressing and molding a metal plate in a metal doorframe machine; secondly, aligning two sides of one doorframe profile along the end parts, and trimming a seam; thirdly, aiming at the seam by using the welding gun of an argon arc welding machine to weld fully; fourthly, cooling the welded doorframe profile by using two cold water valves with a certain space; fifthly, keeping straight the cooled doorframe profile and correcting each angle; sixthly, sending to a correcting machine to correct, and finally, sending to a cutting machine to cut into doorframes with lengths as required. The invention is to provide a method for welding the doorframe profile, and the provided welding doorframe profile has no bumps and has the characteristics of attractive appearance and longer service life.

The invention discloses a panel computer convenient to fix. The panel computer includes a panel computer body, a rear shell, a fixing plate and protection covers. A power switch is embedded on the panel computer body. An indicator light and an electromagnet switch are respectively disposed on two sides of the power switch. The rear shell is fixedly mounted on one side of the panel computer body. The protection covers are disposed in a sleeving manner at all four corners of the panel computer body. Second iron blocks are embedded on all two side walls of each protection cover. Permanent magnets are fixed on all four corners of an inner side of the rear shell. Three electromagnets disposed in a parallel manner are embedded in the middle of the rear shell. Three first iron blocks are embedded on the fixing plate. Positions of the electromagnets correspond to positions of the first iron blocks one by one. Four fixing blocks are welded onto the fixing plate. Each support plate is disposed between the two fixing blocks. One end of each support plate is provided with a rotating member. Through-holes are provided inside all of the rotating members and the fixing blocks. Pin shafts are inserted in a penetrated manner in the through-holes. Horizontal plates and suckers are disposed on the support plates to enable an entire support structure to be more stable. The panel computer is reasonable in design, and suitable for promotion use.
