The slot has an upper edge formed with a slant first surface and a horizontal second surface, and a lower edge formed with a horizontal third surface and a fourth surface, wherein an inner side of the slot is formed with a fifth surface. Each first terminal has an elastic contact having a connection point projecting over the second surface in the slot. Each second terminal has an elastic contact having a connection point projecting over the third surface in the slot. The card-ejecting slant surface is formed between the second and fifth surfaces. The inserted circuit board is moved backward by a distance along the card-ejecting slant surface when the circuit board is rotated to be horizontal.

Abstract: An electrical connector includes two floating bases, an outer casing and a positioning structure. The floating bases may be moved vertically. One row of terminals is disposed on each floating base. Each terminal has an elastic contact and a pin to be bonded to a circuit board. The outer casing engages with the floating bases and covers a top and two sides of each floating base. The positioning structure is disposed on the outer casing and each floating base to make each floating base movable only in a vertical direction.

Abstract: An extension piece for length-reduced memory card includes a base and a case assembled to and covering an outer surface of the base. The case is provided below two lateral sides with two inward open-sided guide channels, front ends of which are adapted to receive two rear corners a length-reduced memory card, and at a top with a retaining structure for releasably engaging with a retaining slot provided at a rear end of the memory card. The extension piece firmly connected to the rear end of the memory card extends the length of the memory card to match the size of an existing card slot on a card reading apparatus, so that the length-reduced memory card could still be conveniently inserted into and moved out of the card slot.

Abstract: Provided is a combination lock and padlock combination comprising a housing include a window; a tumbler wheel assembly; a cylindrical moveable bar inserted through the tumbler wheels; a locking mechanism including a U-shaped member fixed at the bar, a rectangular shuttle member having a central opening, a projection at one side, a spring biased extension at the other side inserted through the shuttle member, and an arcuate recess at an end of the extension, and a parallelepiped indicator assembly fitted in a cavity proximate a shackle receiving hole and including a latch, an internal spring having one end urged against a wall of the cavity, and an indicating face on its top; a U-shaped shackle having an annular groove proximate one end being in contact with the recess; and a cylindrical key turning assembly co-acted with the shuttle member.

Abstract: An electrical connector having two vertically movable bases to enhance overall levelness of pins. The electrical connector includes a bottom base, a positioning structure, and a top base covering over the bottom base. The bottom base includes a mother base and a daughter base, wherein the mother base is formed with an opening, the daughter base is contained in the opening, one row of terminals is arranged on the daughter base, and each of the terminals has an elastic contact and a pin. The positioning structure is formed on the mother base and the daughter base to make the daughter base vertically movable and to horizontally restrict the daughter base in the opening of the mother base.

Abstract: Disclosed is a return mechanism for elevator escape device. The return mechanism mounted at a wall of a car and comprises a drive sheave, upper and lower secondary sheaves, a wheel coaxially disposed with the drive sheave and located on an inner wall of the car, a lever including a lower pivot end, a positioning bar, an upper end at the drive sheave, and a groove, a link having one end defined by the groove and a roller at the other end, a support for permitting the link to slide therethrough, a catch, and projecting return members. In a case of car failure, a trapped passenger is able to continuously rotate the wheel for escape in which the mechanism can automatically return to its original position by moving the link backward after the roller contacting the return member.

Abstract: An engagement structure for engaging with a circuit board formed with first and second notches includes an elastic engagement arm and an elastic ejection arm. The engagement arm can be elastically and laterally moved and has a resting portion protruding laterally and an engagement portion for engaging with the first notch. The ejection arm can be elastically and laterally moved and has a touching portion and an inverse hook. The inverse hook is formed with a guiding bevel and a hooking surface. When the ejection arm is pushed laterally, the engagement portion gradually escapes from the second notch, the guiding bevel gradually presses the circuit board through the first notch, and the ejection arm deforms elastically. When the inverse hook completely passes through the first notch and makes the engagement portion escape from the second notch, the ejection arm rebounds such that the hooking surface hooks the circuit board.

Abstract: An LGA connector is used to interconnect an LGA package and a printed circuit board. The LGA connector includes an elastomeric body with a plurality of through-holes. Metal films are formed on inner walls of through-holes and splay out around the mouths of their upper and lower openings. The metal films are formed by vacuum metallization, sputtering, chemical plating, electrical plating or PVD. The through-holes have a funnel-like shape to absorb external stresses and redirect the stress to shrink the through-hole diameters. Moreover, the metal films' elastic deformation is larger than conventional metal conductive fillers so as to improve reliability.
