A keyswitch structure includes a base, a keycap, a first support, a second support, and a connection structure. The keycap moves up and down relative to the base through the first support and the second support. The connection structure is disposed on the base and includes a vertical-motion limiting part and a horizontal-motion limiting part. The first support includes a rod-shaped connection portion and is connected to the connection structure through the rod-shaped connection portion. The vertical-motion limiting part prevents the rod-shaped connection portion from vertically moving. The horizontal-motion limiting part limits the horizontal movement of the rod-shaped connection portion. The vertical-motion limiting part and the horizontal-motion limiting part are separated in the rotation axis of the rod-shaped connection portion.

Keyswitch structure

A tactile-adjustable keyboard includes plural keyswitches, an adjustment frame and a hybrid operation button. The adjustment frame is disposed corresponding to the keyswitches to move and interfere at least one of the keyswitches. The hybrid operation button includes a tactile switch, a non-tactile knob disposed at least partially surrounding the tactile switch, and a lens disposed at least partially surrounding the non-tactile knob. The tactile switch includes a switch shaft and a switch bar. The switch shaft is disposed in rotatable connection with the adjustment frame to move the adjustment frame. The switch bar extends externally from the switch shaft. A tactile feedback of said one keyswitch changes in response to the rotation of the tactile switch, while a non-tactile signal is generated in response to the rotation of the non-tactile knob, and the lens is illuminated in response to the rotation of the tactile switch.

A trocar includes a puncturing device and a sleeving component. The puncturing device includes a base and a puncturing portion. The puncturing portion includes a bump and a tip. The bump extends from an outer surface of the puncturing portion radially. The sleeving component includes a gas pressure base, a first tube assembly, a second tube assembly, and a fixation base. The second tube assembly is retractable. The fixation base is fixed to the second sleeving end and includes a guiding groove and a key groove. The guiding groove communicates the key groove. While the bump of the puncturing device is entered through the guiding groove, and the puncturing device is rotated to have the bump be in the key groove, the puncturing device is secured to the fixation base, and the puncturing device drives the fixation base to move along an elongated direction of the puncturing device.

Trocar

A keyswitch structure includes a base plate, a keycap, a first support, and a second support. The keycap is located above the base plate. The first support is connected to and between the keycap and the base plate and has an upper connection portion, a lower connection portion, and a protruding limitation portion. The upper connection portion is located between the lower connection portion and the protruding limitation portion. The first support is rotatably connected to the keycap and the base plate through the upper connection portion and the lower connection portion respectively. The protruding limitation portion is located close to and under the cap body. The second support is connected to and between the keycap and the base plate. The keycap moves up and down relative to the base plate through the first support and the second support.

A liquid composition includes copper particles, an organic acid, and a solvent. The copper particle has a particle size of 0.5 &#x3bc;m&#x2dc;30 &#x3bc;m which falls in a micron scale. The liquid composition performs reaction sintering by redox reactions taken place between the copper particles and an organic acid solution at a low temperature of 150&#xb0; C. in order to produce a dense copper layer and improve the conventional micron-scale copper particles that requires a protective atmosphere for the high-temperature sintering before achieving the required densification. This liquid composition also prevents an excessive oxidation of the nano copper particles during the low-temperature sintering process and a failure of the dense sintering. Due to the agglomeration of nano copper particles, some areas have to be sintered first, so that the sintered products have a good uniformity of tissue and a low resistance below 0.04 ohm per square (&#x3a9;/&#x25a1;).

A trocar set includes a handle portion, a first sleeve, a second sleeve, and a gas tight assembly. The handle portion includes a grip, a connection part, and a second gas valve. The connection part extends from the grip and includes an assembling channel. The second gas valve is connected to the connection part and communicates with the assembling channel. An assembling end of the first sleeve is assembled to the connection part. The second sleeve includes a receiving end, wherein the sleeving end is inserted into the receiving end. The gas tight assembly is fixed to the second sleeve and includes a gas tight sleeve and a gas tight ring. The gas tight sleeve encloses the receiving end, and the gas tight ring is pressed by the gas tight sleeve to be tightly attached to the first sleeve.

Trocar set

A trocar set includes a handle portion, a first sleeve, a second sleeve, and a gasbag. The handle portion includes a grip, a connection part, and a first gas valve. The connection part extends from the grip and includes an assembling channel. The first gas valve is connected to the connection part and communicates with the assembling channel. An assembling end of the first sleeve is assembled to the connection portion. A sleeving end of the first sleeve is provided with a first opening. The second sleeve is retractably connected to the sleeving end of the first sleeve. A sleeve wall of the second sleeve is provided with a second opening. The gasbag is connected to an end of the second sleeve away from the sleeving end and corresponds to the second opening. The design of the retractable sleeves is benefit to perform operation.

The invention provides an electronic device including a user operable device and a foldable cover flexibly connected to the user operable device and capable to cover a whole top of the user operable device. The foldable cover includes a plurality of sections and a plurality of foldable lines, so that the foldable cover can be folded along the plurality of foldable lines formed between different sections. The sections are connected through the flexible foldable lines to allow the adjacent sections foldable with respective to one another to make the foldable cover in a supporting state, so that a first fastening section and a second fastening section are releasably fastened together so as to fasten a first supporting section and a second supporting section, and a first attachment section and a second attachment section are placed flatly on a plane.

Electronic device with a foldable cover for covering a user operable device

The invention discloses a keyboard device including a keyboard and a support for protecting the keyboard or accommodating a portable information processing device. The support of the invention is capable of rotate in a direction away from the keyboard to be at a supporting state. The support of the invention is also capable of rotate in a direction toward the keyboard to cover whole of the top of the keyboard.
