Abstract: A color calibrator includes a first casing, a second casing and an optical sensor. The first casing has an accommodating recess and a plurality of first positioning members, wherein the first positioning members are arranged along an axial direction of the accommodating recess. The second casing is telescopically disposed in the accommodating recess. The second casing has a second positioning member. One of the first positioning member and the second positioning member is a magnet. Another one of the first positioning member and the second positioning member is a magnet or a magnetic induction material. The second positioning member cooperates with one of the first positioning members to position the second casing at one of a plurality of telescopic positions with respect to the first casing. The optical sensor is disposed on the second casing.

Abstract: A planar-part-based toy assembly set includes planar parts that have different shapes and are made by stamping a planar material board. The planar parts include a body piece and a limb piece. The body piece has a slotted ring for coupling with the limb piece. The slotted ring has a cutting slot, a narrow section and, a wide section. The limb piece has a closed ring, or a slotted ring as stated above. The closed ring of the limb piece can pass through the cutting slot of the slotted ring of the body piece and be mounted around the narrow or wide section of the slotted ring. When the closed ring is around the narrow section, the limb piece can freely swing, and when the closed ring is around the wide section, the limb piece is fixed at a specific angle, which can be later adjusted by the player.

Abstract: A method of forming a short channel field effect transistor is disclosed. The method includes the steps of providing a semiconductor substrate having a well region of a first conductivity type; forming a gate electrode on the well region; implanting first impurities into the well region and adjacent to the gate electrode, the first implant step being at a first dose and a second conductivity type; forming sidewall spacers on edges of the gate electrode; implanting second impurities into the well region and adjacent to the gate electrode, the second implant step being at a second dose and at the second conductivity type; and implanting third impurities into the well region and adjacent the gate electrode, the third implant step being at a third dose and at the first conductivity type.
