Abstract: A method and apparatus are for contactless-printing on tablets that are supplied successively at random spacings in the conveyance direction, respectively in plural rows. The apparatus includes a hopper to supply tablets, a distributing unit to distribute the supplied tablets in plural rows, a conveyor to convey the tablets randomly with the random spacings in the conveyance direction and with the rows maintained, a detection camera to detect the tablets during conveyance, an inkjet printer to print on the tablets based on data detected by the detection camera, an inspection camera to check a printing state on the tablets, and a defective tablet rejection unit to reject a defective tablet during conveyance of the tablets based on the check result of the inspection camera.

Abstract: The present invention provides a tablet printing method and apparatus for contactless-printing on a large number of tablets that are supplied successively and randomly in a predetermined plurality of rows. The apparatus includes a hopper 2 to supply tablets, a distributing unit 3 to distribute the supplied tablets in a predetermined plurality of rows, a conveyor 4 to convey the distributed tablets randomly with the plurality of rows maintained, a detection line sensor camera 5 to detect the tablets during conveyance of the conveyor 4, an inkjet printer 6 to print on the tablets during conveyance based on data detected by the detection line sensor camera 5, an inspection line sensor camera 7 to check printing state on the tablets, and a defective rejection unit 9 to reject a defective during conveyance of the tablets in the plurality of rows based on the check result of the inspection line sensor camera 7.

Abstract: A semiconductor device includes a decoder receiving first multiplier data of 3 bits indicating a multiplier to output a shift flag, an inversion flag, and an operation flag in accordance with Booth's algorithm, and a first partial product calculation unit receiving first multiplicand data of 2 bits indicating a multiplicand, a shift flag, an inversion flag, and an operation flag to select one of the higher order bit and lower order bit of the first multiplicand data based on the shift flag, invert or non-invert the selected bit based on the inversion flag, select one of the inverted or non-inverted data and data of a predetermined logic level based on the operation flag, and output the selected data as partial product data indicating the partial product of the first multiplier data and the first multiplicand data.
