Abstract: The present disclosure relates to a MIM (metal-insulator-metal) capacitor having a top electrode overlying a substrate. A passivation layer overlies the top electrode. The passivation layer has a step region that continuously contacts and extends from a top surface of the top electrode to sidewalls of the top electrode. A metal frame overlies the passivation layer. The metal frame continuously contacts and extends from a top surface of the passivation layer to upper sidewalls of the passivation layer in the step region. The metal frame has a protrusion that extends through the passivation layer and contacts the top surface of the top electrode.

Abstract: Various embodiments of the present disclosure are directed towards an integrated chip including a dielectric structure sandwiched between a first electrode and a bottom electrode. A passivation layer overlies the second electrode and the dielectric structure. The passivation layer comprises a horizontal surface vertically below a top surface of the passivation layer. The horizontal surface is disposed above a top surface of the dielectric structure.

Abstract: Various embodiments of the present disclosure are directed towards a piezoelectric metal-insulator-metal (MIM) device including a piezoelectric structure between a top electrode and a bottom electrode. The piezoelectric layer includes a top region overlying a bottom region. Outer sidewalls of the bottom region extend past outer sidewalls of the top region. The outer sidewalls of the top region are aligned with outer sidewalls of the top electrode. The piezoelectric layer is configured to help limit delamination of the top electrode from the piezoelectric layer.

Abstract: A PC cartridge having enhanced front connecting structure is disclosed. Two folded hooks with n-shaped structure are on the same side of the front connector and at two front corners of the upper shell. The folded hook defines a small height and has a rearward opening. Further, first and second flanges are located on the same side of the front connector and at the front ends of the packing rubbers located on the bottom shell. Especially, first and second flanges are parts extended from the packing rubbers, whereby retaining slots are formed between upper and bottom shells. Both the second flanges comprise a third flange projected forward. The folded hooks conform to the third flange and extend into the retaining slots so as to engage the upper shell with the bottom shell.

Abstract: A PCMCIA card converter connector includes a PC card casing; a connector casing for connecting to the PC card casing and having an accommodating room formed at an interior thereof; a plurality of USB connector sockets or at least one IEEE1394 connector socket disposed at one end face of the connector and are for inserting USB connectors or IEEE1394 connectors; and a connector circuit board disposed in the accommodating room and provided with a PCMCIA connector interface at a rear end portion thereof. The USB or IEEE1393 connector sockets are electrically connected to a front end portion of the connector circuit board for converting electric signals of the connector into electric signals of the PCMCIA connecter interface, thereby accomplishing an object of converting a PCMCIA card into a USB connector or an IEEE1394 connector.

Abstract: The invention herein relates to a removable casing for memory card includes: an upper cover, a casing, a frontal cover and a lower cover wherein the casing is devised with a linkage terminal to be in contact with a memory card, the front of the casing is to receive the frontal cover while on either side of the casing extends a rod. The top and the bottom of the rod are each fitted with a plurality of notches, while on either side of the upper cover is at least one “U shape” catch and on either side of the lower cover is at least one “Inverse L shape” catch. The catches are to correspond to the notches for a match interlocking. The inside edges of rods are connected to a press board to exert pressure onto the linkage terminals to enhance the perfect evenness and overall steadiness of the terminals.

Abstract: A PC cartridge is provided at two front corners of an upper shell with two folded hooks that define a predetermined small height and rearward openings, and at two front ends of two packing rubbers attached to two sides of a bottom shell of the PC cartridge with two retaining slots, each of which includes a forward projected flange portion. When the upper shell is closed onto the bottom shell, the folded hooks extend into the retaining slots to fitly engage with the flange portions and therefore be retained to the retaining slots. The engagement of the folded hooks with the flange portions of the retaining slots produces a vertical coupling stress, enabling the coupled upper and bottom shells of the PC cartridge to resist increased pull applied on them without easily becoming deformed.

Abstract: A PC cartridge for computers/game machines, including a bottom shell, an upper shell covered on the bottom shell, a PC board mounted within the bottom shell and the upper shell, and two connection ports connected to two opposite ends of the PC board, wherein the upper shell and bottom shell have a respective pair of locating flanges transversely disposed at two opposite ends and respectively forced into engagement with top and bottom locating grooves of the connection port; the bottom shell has two packing rubbers molded thereon along its two long sides and adapted to hold the connection ports therebetween; the upper shell has two downward front hooks respectively hooked in a respective front hook hole in the packing rubbers, two downward rear hooks respectively hooked in a respective rear mounting groove of the packing rubbers, and two L-shaped coupling flanges raised along its two long sides and respectively forced into engagement with the bottom edges of the packing rubbers.

Abstract: An elongated rod-like gas lighter has a rod body for storing gas therein, an ignition base mounted on the upper end of the rod body, the ignition base having a circumferential groove-shaped hole through the wall thereof adjacent the point of attachment to the rod body, a gas adjustment ring rotatably mounted around the ignition base and movably engaged with the upper end of the rod body and having a threaded hole radially therethrough and a gas supply adjusting screw therein extending through the circumferential groove-shaped hole, a gas nozzle tube within the ignition base having the upper end extending upwardly out of the ignition base, and a rotatably operable gas flow adjusting valve on the upper end of the rod body and receiving the lower end of the gas nozzle tube, the gas supply adjusting screw being engaged with the outside of the gas flow adjusting valve for rotating the gas flow adjusting valve when the gas adjusting ring is rotated on the ignition base.
