Abstract: An electrolytic capacitor includes a core package formed by stacking and rolling an anode foil, a cathode foil, a plurality of paper spacers, and two terminal leads. The core package includes a solid electrolyte layer. The solid electrolyte layer is impregnated with an electrolytic solution. The electrolytic solution includes an ester compound and a sulfone compound. A content of the ester compound is more than 30% by mass. A content of the sulfone compound is more than 40% by mass. The sum of the contents of the ester compound and the sulfone compound is larger than 90% by mass. Thus, an electrolytic capacitor with excellent reliability is provided.

Abstract: In a stylus attachment structure for an IT product, the attachment structure formed on an IT product, such as, a laptop, a tablet PC and a PDA, comprises an attachment slot, a push-out member, a retaining member and an elastic part, wherein the push-out member is arranged in the attachment slot and the retaining member is slidably mounted at one end of the attachment slot for selectively retaining or releasing the stylus. In this way, when the stylus is not in use for a while, it can be obliquely plugged to one end of the attachment slot, it is easy for the user to pick up the stylus; alternatively, the stylus can be fully received in the attachment socket and further secured in place with a retaining member, thereby enabling the stylus to be attached properly so that it doesn't become loose.

Abstract: A flat-type computer with a foldable keyboard has a main body with a chamber formed in rear side of the main body and a back cover to cover the chamber, the hosing connected with the rear side of the main body by a pivot, a keyboard, received in the chamber and a pivoting mechanism for connecting the main body and keyboard.

Abstract: The present invention discloses a hinge assembly for notebook computers capable of keeping a screen of a monitor connected face-to-face with a main system of the notebook, and such hinge assembly also can keep an included angle between the monitor and the main system from zero degree (i.e. closed status for stacking the monitor and the main system) to 180 degrees (i.e. horizontally aligned status of the monitor and the main system). Furthermore, the monitor can continue to be turned over until the screen of the monitor faces the back of the main system, and then further till the monitor and the main system are in the back-to-back contact with each other.
