Abstract: A semiconductor mixed material comprises an electron donor, a first electron acceptor and a second electron acceptor. The first electron donor is a conjugated polymer. The energy gap of the first electron acceptor is less than 1.4 eV. At least one of the molecular stackability, ?-?*stackability, and crystallinity of the second electron acceptor is smaller than the first electron acceptor. The electron donor system is configured to be a matrix to blend the first electron acceptor and the second electron acceptor. The present invention also provides an organic electronic device including the semiconductor mixed material.

Abstract: An apparatus includes a six-axis correction stage, an auto-collimation measurement device, a light splitter, a telecentric image measurement device, and a controller. The six-axis correction stage carries a device under test; the auto-collimation measurement device is arranged above the six-axis correction stage along a measurement optical axis; the light splitter is arranged on the measurement optical axis and is interposed between the six-axis correction stage and the auto-collimation measurement device. A method controls the six-axis correction stage to correct rotation errors in at least two degrees of freedom of the device under test according to a measurement result of the auto-collimation measurement device, and controls the six-axis correction stage to correct translation and yaw errors in at least three degrees of freedom of the device under test according to a measurement result of the telecentric image measurement device by means of the controller.

Abstract: A roller input device includes a housing, a passive member and an active member. A roller is pivotally disposed inside the housing, and the roller includes an annular tooth portion. The passive member is movably disposed inside the housing, and the passive member includes an abutting portion and a first magnetic module. The active member has a second magnetic module, and the active member is disposed inside the housing and operably moved to a first mode or a second mode to make the first magnetic module and the second magnetic module attract each other or make the first magnetic module and the second magnetic module repel each other to drive the passive member to move relative to the housing to a first position or a second position, such that the abutting portion and the annular tooth portion abut against or separate from each other.

Abstract: A keyboard includes a circuit board on which a silo is formed. A pushbutton structure includes a cap from which a post extends. The post is movably received in the silo whereby the cap is movable between a released position and an actuated position. The keyboard includes a resilient cone supporting the post at the released position. When the pushbutton is depressed, the cap moves from the released position to the actuated position where the post deforms the cone to trigger a contact switch of the circuit board and generate a signal indicating the depression. Two resilient slide tabs are formed on opposite sides of the post and each slide tab has an inclined surface for resiliency-biased engagement with an inside surface of the silo to ensure stable and sound movement of the cap with respect to the silo. A stop bar is mounted to the post by two fingers on opposite sides of each slide tab. The stop bar is selectively engageable with an internal shoulder of the silo to retain the cap at the released position.
