A conveyor conveys glass sheets horizontally, while holding them in an upright orientation. Film feed units are provided on both sides of a conveyance path of the glass sheets. Nip rollers press against both surfaces of the glass sheets via films fed from the film feed units so as to sandwich the glass sheets, while the glass sheets are being conveyed by the conveyor.

The invention discloses a pressure device for correction of dental bracket grooves. The pressure device comprises a device body; a sliding cavity with a forward opening is formed in the device body; amoving cavity with a forward opening is formed in the lower side of the sliding cavity in a communicating manner; a sliding block capable of being applied to correction is arranged on the back wall of the sliding cavity in an up-and-down sliding manner; a control mechanism capable of controlling the sliding block to slide up and down in a reciprocating manner is arranged on the front side surfaceof the device body; and two bilaterally-symmetric driven cavities are formed in the back side of the sliding cavity. By the aid of the pressure device, the operation efficiency of the correction procedure for the dental bracket grooves can be improved effectively, the production number can be increased, the labor cost can be reduced, brackets can be replaced manually and continuously while a correction rod reciprocates continuously for correction, the correction time can be shortened greatly, and power for reciprocating operation of the control mechanism can be provided by a reciprocating mechanism.

A wafer having a device region, where a plurality of devices is formed, and an outer peripheral surplus region, which surrounds the device region, on the face of a circular wafer substrate is disclosed. A chamfered portion whose cross-sectional shape defines an arc-shaped surface in a range from the face to the back of the wafer substrate is formed in an outer peripheral end portion of the outer peripheral surplus region of the wafer substrate. A flat surface orthogonal to the face and the back is formed in the chamfered portion as a mark showing the crystal orientation of the wafer substrate. An identification code for specifying the wafer substrate is printed on the flat surface.

The invention relates to a manufacturing process of vacuum glass, which comprises the following steps: (1) sheet binding, that is, cutting an upper and a lower piece of flat glass into sheets, placing a supporting substance between the two pieces of glass, placing a low-melting glass powder or a binder between the upper and the lower piece of flat glass, welding and mounting an air exhaust glass tube at the side edge or the side surface of the angle part, wherein the air exhaust glass tube is a sealed glass tube; (2) heating for edge sealing in a high-temperature heating box; (3) orderly placing the glass with a sealed edge into a clamping frame which is fixedly mounted on a bottom plate in an air exhaust box of a low-temperature heating furnace; (4) vacuum pumping, that is, starting a vacuum pump, performing vacuum pumping of a cavity in the vacuum glass to reach a set vacuum degree, performing hot-melt sealing of the air exhaust tube by an electrically-fusing electrode, cooling to room temperature, taking the product out of the furnace to obtain the vacuum glass. In the manufacturing process of vacuum glass, the air exhaust tube mounted in the high-temperature heating box is a blind-hole tube, and thus during the cooling process after the edge sealing of the vacuum glass, outdoor air is prevented from entering the vacuum glass cavity; the air in the cavity is maintained to be dry; the specific gravity of the air in the cavity is decreased; the vacuum degree in the cavity is increased; during the vacuum pumping of the cavity, the air exhausting efficiency is increased; procedures for removing moisture in the cavity is reduced; and the quality of the vacuum glass is guaranteed.

The invention relates to an improved structure of a mold assembly for greatly improving the casting precision of lightweight aluminum pistons, which is applied to mass production of high-precision lightweight aluminum pistons. It includes outer mold, pin hole mold, slider mold and core mold. The mandrel includes a piston mandrel centerpiece. The central part of the piston mandrel consists of a quadrangular pyramid column and a supporting platform connected with the quadrangular pyramid column. It is characterized in that the support rail opens the groove along the center line, the bottom of the pin hole mold has a straight rod, the straight rod is as wide as the through groove and extends into the through groove; the upper part of the pin hole mold has a T-shaped guide rail groove, and the upper part of the outer mold cavity With T-shaped guide rail, the T-shaped guide rail groove is set on the T-shaped guide rail. The pin hole die has a lower pressing block for the pin hole. The quadrangular pyramid column and the supporting platform are fastened and connected by bolts with chord sections. The end face hole of the bolt is connected with the side hole of the bolt, and a deep hole of the square pyramid column is opened on the lower end surface of the square pyramid column. It has the advantages of avoiding various abnormal wear and tear of the pin hole mold, greatly enhancing the anti-turbulence performance, and improving the precision of the thickness of the radial casting involved in the slider mold during production.

A lithium-ion secondary battery is provided where the production process line that fabricated it can be identified. The lithium-ion secondary battery includes a jelly roll, a positive electrode tab, a negative electrode tab, a positive electrode can, and a lid. The jelly roll is made by rolling the positive electrode and the negative electrode with an interposed separator, and is contained in the casing. The positive electrode tab has one end connected to the positive electrode of the jelly roll and the other end connected to the lid. The negative electrode tab has one end connected to the negative electrode of the jelly roll and the other end connected to a terminal provided on the lid. The other end of the negative electrode tab has a shape with a cut at a cut angle determined in accordance with the production process line that fabricated the lithium-ion secondary battery.
