A multidirectional switch (1) comprises an insulative housing (2), a first fixed contact (31) and a third fixed contact (33), a first moveable contact (41) and a second moveable (42) contact disposed above the first fixed contact (31) and the third fixed contact (33), an operation member (5) mounted on the first moveable contact (41) and defining a second pressing portion (53). The second pressing portion (53) presses the second moveable contact (42) in order to make the second moveable contact (42) contact with or separate from the third fixed contact (33). The first moveable contact (41) always contacts with the first fixed contact (31). The second moveable contact (42) is integrated with the first moveable contact (41) and distributed around the first moveable contact (41).

An improved automatic shutoff nozzle tip which is mounted on the downstream end of a nozzle body of an injection molding machine or the like who's purpose is to act as a passageway for molten plastic fluid allowing the fluid to flow in one direction when urged to open by the pressure created by the forward motion of the plasticizing screw of said molding machine and to close when said pressure is lower than the designed opening pressure. The nozzle, having an convex outwardly extended portion that mates up with a sprue bushing or mold having complimentary convex radii, said nozzle having a orifice on the distal end that mates with a complimentary orifice of said sprue bushing. A nozzle that has a means for attachment to a nozzle body or the like with a rear seat, poppet and spring or similar device who's poppet is normally in the closed position until pressure is applied urging the poppet to move in the downstream direction and providing for a passageway for molten plastic fluid.

A miniaturized lens assembly includes a front lens portion, a rear lens portion, a large diaphragm plate mounted between the front and rear lens portions, a small diaphragm plate rotatable relative to the large diaphragm plate, a shutter plate rotatable relative to the large diaphragm plate, first and second actuating elements mounted on the rear lens portion, and two pivot axles mounted between the front and rear lens portions. The miniaturized lens assembly is miniature in size, is simple in structure, and is easy to assemble.

The present application relates to the technical field of semiconductor integrated circuit manufacturing, and in particular, to a floating gate type split-gate flash memory device structure and a manufacturing method thereof. The method includes: forming a floating gate oxide layer, a floating gate polysilicon layer, a polysilicon spacer layer, and a control gate polysilicon layer in sequence on a flash memory region of a substrate of a first conductivity type; defining a flash memory cell region; forming a first conductive type anti-penetration injection region; depositing a first dielectric layer; etching the first dielectric layer to form a first spacer; using the mask layer and the first spacer as a mask, not covering the first spacer The control gate polysilicon layer and the polysilicon spacer layer are removed by etching; the first conductivity type halo implantation is performed to form the first conductivity type halo; the second dielectric layer is deposited, and the second sidewall spacer is formed by etching; The floating gate polysilicon layer and the floating gate oxide layer of the sidewall spacer and the second sidewall spacer are removed by etching; the second sidewall spacer and the first sidewall spacer are used as masks to form a second conductive type implantation region.

This invention discloses a mobile device, comprising a metal mechanism member and a feed-in structure. The metal mechanism member isroughly plane-structured, wherein a slotted hole is formed in the metal mechanism member. The feed-in structure is roughly positioned in the slotted hole and coupled to a signal source. The metal mechanism member, the slotted hole and the feed-in structure form an antenna structure. The metal mechanism member and the slotted hole are seemed as a slotted antenna which generates a low frequency band by excitation, and the feed-in structure is excitated to generate one or more than one high frequency bands. The mobile device can not only effectively reduce the overall size of the antenna structure, but also can maintain sound antenna radiation efficiency.

Mobile device and antenna structure. The mobile device includes a metal mechanical component, a ground plane, first and second parasitic radiation parts, a feeding radiation part and a dielectric substrate; the metal mechanical component has a slot, wherein the slot has a first and a second closed end; the first and the second The two parasitic radiating parts are both coupled to the metal mechanism and extend across the slot; the feeding radiating part has a feeding point, wherein the feeding radiating part is arranged between the first parasitic radiating part and the second parasitic radiating part; the medium The substrate is adjacent to the metal mechanical component, and the feed-in radiation part, the first parasitic radiation part and the second parasitic radiation part are arranged on the dielectric substrate; the feed-in radiation part, the first parasitic radiation part, the second parasitic radiation part and the metal mechanical component The slots together form an antenna structure; the antenna structure covers at least one first frequency band, and the length of the slots is less than 0.48 times the wavelength of the first frequency band. The invention has the advantages of small size, wide frequency band and beautifying the appearance of mobile devices, and is suitable for various mobile communication devices.
