A zoom lens includes a first lens, a first lens barrel, a shutter assembly, and a guide barrel. The first lens barrel houses the first lens. The shutter assembly is positioned on a distal end of the first lens barrel toward an object side of the zoom lens. The guide barrel is received in the first lens barrel and configured for guiding the first lens barrel to move along the optical axis of the zoom lens.

A non-oriented electrical steel has relative high magnetic induction and high intensity without increasing manufacturing difficulty. The weight percentage of the compositions of the electrical steel are as follows: C≦0.0040%, Si is 2.50% to 4.00%, Al is 0.20% to 0.80%, Cr is 1.0 to 8.0%, Ni is 0.5 to 5.0%, Mn≦0.50%, P≦0.30%, S≦0.0020%, N≦0.0030%, Ti≦0.0030%, Nb≦0.010%, V≦0.010%, C+S+N+Ti≦0.010%, and a balance substantially being Fe and inevitable impurities.

A zoom lens includes a lens, a shutter-aperture, a moving barrel and a resisting ring. The lens includes a curved surface. The shutter-aperture includes a diaphragm for allowing light rays passing through and at least three blind holes. The moving barrel includes a bottom plate, a securing portion for securing the lens, at least three protrusions surrounding the securing portion and at least three elastic elements sleeved on the protrusions respectively. The securing portion and the at least three protrusions extend towards the object-side from the bottom plate. The resisting ring is disposed on an end of the moving barrel opposite to the bottom plate. The aperture-shutter is received in the moving barrel and the movement of the aperture-shutter is bounded by the resisting ring. When the zoom lens contracts, the protrusions are received in the blind holes correspondingly and the lens is received in the diaphragm.

A zoom lens barrel includes a fixed barrel, a guide barrel received in the fixed barrel, a cam barrel received in the fixed barrel and housing the guide barrel, a zoom barrel sandwiched between the guide barrel and the cam barrel, and a lens cover covering on the zoom barrel. The cam barrel includes a flange radially formed on an end close to the lens cover. The zoom barrel includes a ring portion protruding out from an end close to the fixed barrel. A step surface is formed between the outer side surface of the zoom barrel and that of the ring portion. When the zoom lens barrel is in an unfolded state, the step surface interferingly resists against a bottom surface of the flange, to limit an axial movement between the cam barrel and the zoom barrel.

A zoom lens includes a substrate, an imaging unit, a stationary lens barrel, a cam lens barrel and a guide lens barrel. The substrate defines a plurality of openings thereon. The imaging unit is attached on the substrate. The stationary lens barrel is mounted on the substrate and surrounding the imaging unit. The cam lens barrel is rotatably received in the stationary lens barrel and movable along the optical axis of the zoom lens as the rotation thereof along the inner circumference of the stationary lens barrel. The guide lens barrel is received in the cam lens barrel and movable axially following the motion of the cam lens barrel, and comprises a plurality of key numbers protruding outwards from the outer circumference corresponding to and received in the openings of the substrate when the zoom lens is positioned in the minimum focal length position.

An unoriented silicon steel having high magnetic conductivity and low iron loss at a working magnetic density of 1.0-1.5 T and method for manufacturing same. By proper deoxidation control in a RH refining and high-temperature treatment for a short time in a normalizing step, the method can reduce the amount of inclusions in the silicon steel and improve grain shape, so as to improve the magnetic conductivity and iron loss of the unoriented silicon steel at a magnetic density of 1.0-1.5 T.

A manufacture method of high-efficiency non-oriented silicon steel with excellent magnetic property includes the steps of smelting a chemical composition of non-oriented silicon steel, by weight percent, is: C≦0.0040%, Si:0.1˜0.8%, Al:0.002˜1.0%, Mn:0.10˜1.50%, P:≦0.2%, Sb:0.04˜0.08%, S≦0.0030%, N≦0.0020%, Ti≦0.0020%, and the rest is Fe and unavoidable inclusions. The molten steel is then cast into billets which are hot-rolled into a hot-rolled product. The heating temperature for the billet is 1100°˜1150° and the finish-rolling temperature is 860°˜920°. The hot-rolled product is then air cooled for a period of time within a range determined by air cooling time t: (2+30xSb %)s≦t≦7 s. The hot-rolled product is reeled at a temperature ≧720° and cold-rolled to form cold-rolled plate with a target thickness at a reduction ratio of 70˜78% followed by heating up the cold-rolled plate to 800˜1000° at heating rate of ≧15°/s, and holding time of 10 s˜25 s.
