Abstract: A rotatable plug with an arcing resistant mechanism is disclosed which includes an upper cover, a lower cover mating with the upper cover to form a holding space, a mount placed in the holding space, a rotatable rack placed on the mount, a pair of conductive terminals fixed on the lower cover and a pair of connecting slices. The rotatable rack includes a pivot and a pair of prongs, wherein the prongs are fixed on the both ends of the pivot respectively. Each connecting slice connects the corresponding prong of the rotatable rack with the corresponding conductive terminal. Therefore a circuit exists between the prongs and the conductive terminals, so that the rotatable plug with an arcing resistant mechanism can suppress the arcing that is produced between the prongs and the conductive terminals. Thus the rotatable plug with an arcing resistant mechanism is used safely and has a long lifetime.

It is possible to prevent branches inserting into the seam and enrich the appearance of gardening scissors.

Abstract: A quality prognostics system and a quality prognostics method for predicting the product quality during manufacturing processes are disclosed. The present invention utilizes the current production tool parameters sensed during the manufacturing process and several previous quality data collected from the measurement tool to predict the future product quality.

The retaining elastic pin extends a retaining portion towards the memory card for engagement with a groove on one side of the memory card, so that the memory is stably and reliably retained and the card connector is compact and light-weight.

Abstract: The present invention relates to a process for preparing water-soluble and dispersed iron oxide (Fe3O4) nanoparticles and application thereof, characterized in which two-stage additions of protective agent and chemical co-precipitation are employed in the process. In the first stage, Fe3O4 nanoparticles are obtained using absorbent-reactant coexistence technology. In the second stage, proper amount of adherent is added to cover the nanoparticle surface entirely. The resulting water-soluble and dispersed Fe3O4 nanoparticles can easily bind with thiols or biomolecules, such as nucleic acid and peptide. The Fe3O4 nanoparticles of the present invention may be used as magnetic resonance imaging contrast agent and used in magnetic guiding related biomolecular technologies for clinical testing, diagnosis and treatment.

Abstract: The present invention provides an open/close type electrical connector comprising, a base member, a terminal modular member positioned in the base member, and a cover member positioned on the base member. The cover member pivotally connects with the rear portion of the base member and rotates between an open position and a close position. When the cover member is opened, a receiving space is formed between the base member and the cover member to receive a mated plug. A restricting mechanism is further disposed at a lateral side of the base member for restricting an opened angle of the cover member with respect to the base member. An automatic close mechanism is disposed between the base member and the restricting mechanism so as to close the cover member automatically. Therefore, the open/close type electrical connector is capable of being closed to be a small and thin member automatically and without any accessorial operation by users when not used.

Contacting portions of the second contact terminals extend into the second receiving space. Soldering portions of the first and the second contact terminals all extend outwardly from the rear of the card connector. Therefore, the first and the second contact terminals can be easily soldered on a printed circuit board and entirely contact with contact pads of the electronic cards.
