Abstract: A biosensor with a dual gate structure is disclosed herein. The biosensor comprises: a transistor, a sensing pad, and a plurality of nanostructures. The sensing pad has a conductive area working as another gate and neighboring to the channel layer of the transistor, and a sensing area extended outward from the conductive area to be far away from the channel layer of the transistor, wherein the gate and the conductive area of the sensing pad are separated from each other by the channel layer. The plurality of nanostructures are utilized to bind a first protein to generate a drain current value, when the first protein is combined with the target protein and another drain current value is generated, whereby a variation between the two drain current values is calculated to obtain the concentration of the target protein in the protein solution.

Abstract: The present invention relates to a weight-balancing structure for rotary polygon mirror of color laser printer, 1 which includes a stator set, a rotor set having a loading disc fixed on a spindle, a motor housing disposed underneath the loading disc, and a rotary polygon mirror is fixedly integrated with the loading disc with a spring member. The spring member has a plurality of spring paws disposed around the circumference thereof and obliquely extended in a downward direction. At least two spring paws are further integrally formed with a ring portion, and the ring portion is located around the outer circumference of each spring member and formed to curl in an upward direction. The weight block could be stuck on the inner periphery of the ring portion by an adhesive-applying means so that it won't come off while positioned in an environment of high rotation speed.

Abstract: An electrical connector includes a dielectric housing having a front mating face, a rear terminating face, a bottom mounting face and a plurality of terminal-receiving passages extending rearwardly of the front mating face. A plurality of terminals are received in the passages. A stamped and formed metal boardlock is mounted on the housing and includes a generally planar mounting plate disposed generally parallel to the front mating face of the housing. A pair of locking legs are formed out of a bottom edge of the mounting plate and project below the bottom mounting face of the housing for insertion into an appropriate hole in the printed circuit board. One of the locking legs is generally coplanar with the mounting plate and has a locking portion formed generally perpendicular to the mounting plate and, in turn, perpendicular to the front mating face of the housing. The other locking leg is generally flat and L-shaped in a plane generally perpendicular to the mounting plate.
