Abstract: An inspection apparatus is capable for inspecting at least one light-emitting device. The inspection apparatus includes a working machine and an inspection light source. The inspection light source is disposed on the working machine and located above the light-emitting device. A dominant wavelength of the inspection light source is smaller than a dominant wavelength of the light-emitting device so as to excite the light-emitting device and get an optical property of the light-emitting device.

Abstract: A splitting apparatus suitable to split a work piece along at least one cutting line formed on the work piece is provided. The splitting apparatus includes a chopper, a detector, a controller and an adjustor. The chopper is disposed above the work piece. The detector is disposed above the work piece for transmitting a signal to the work piece so as to get a specification data of the work piece. The controller connects the detector and receives the specification data and generates an adjustment data. The adjustor connects the controller and the chopper. The adjustor receives the adjustment data and adjusts a parameter data of the chopper according to the adjustment data so that the chopper splits the work piece for once along the cutting line formed on the work piece.

Abstract: A power hand tool includes a housing; an electric motor mounted in the housing for provide a rotary motion; a transmission gear set is mounted in the housing and connected with the electric motor; a torsion control device having a first rotary knob, which can adjust the maximum torsion output of the transmission gear set while being turned, and a plurality of first dents formed on an internal periphery thereof; an impact device having a second rotary knob, which can switch on or off an impact motion generated on the transmission gear set while being rotated, and a plurality of second dents formed on an internal periphery thereof; and a locating device having a holder fixed to the torsion control device and a locating member mounted to the holder, the locating member having two resilient portions, each of which has a convexity engaged with the associated first dents or second dents.

Abstract: A power hand tool includes a housing, a motor, a speed change gear set, gearshift position control device, and a display member. The housing includes a longitudinal sliding slot. The motor mounted inside the housing. The speed change gear set is mounted inside the housing. The gearshift position control device is movably mounted in the longitudinal sliding slot to shift the speed change gear set to one of a series of gearshift positions for multi-speed output of the motor, having an indication zone and a display member. The indication zone has multiple numerical signs corresponding to the gearshift positions. The display member is fixedly mounted in the longitudinal sliding slot, having a light-penetrable display zone capable of magnification and corresponding to the indication zone for magnifying one of the numerical signs, and a lamp mounted inside the housing for illuminating the indication zone.

Abstract: A power hand tool includes a housing containing a motor, a speed changing gear set coupled to the power output end of the motor, a transmission mechanism coupled to the speed changing gear set and partially extending out of the housing for operation by the user to selectively shift the speed changing gear set to one of a series of gearshift positions thereof, a set of index signs marked on the transmission mechanism corresponding to the series of gearshift positions and alternatively moved to a sighthole in the housing subject to the gearshift position of the speed changing gear set, and a light emitting device mounted in the housing adjacent to the sighthole for illuminating one index sign of the transmission mechanism that is in alignment with the sighthole.
