The method for cutting off glass panes from a continuously produced glass sheet includes continuously testing the glass sheet for glass faults prior to the cutting off process and determining glass sheet regions to be discarded containing the glass faults. Based on the test results for the glass faults an optimized cutting pattern for a predetermined glass sheet section is calculated in a cutting optimization device, which is a plan for cutting the glass sheet section into crosscut pieces, in which glass panes of respective sizes are arranged next to each other in corresponding crosscut pieces. In order to reduce waste, the cutting lines for the glass panes to be cut away within each crosscut piece are placed sufficiently close to the fault-containing glass sheet regions, so that widths (BS) of the glass sheet regions to be discarded are minimized or the glass sheet regions to be discarded are minimized, while accounting for a largest possible number of usable glass panes. The crosscut pieces are subsequently cut according to the optimized cutting pattern and the glass panes are formed. An appropriate apparatus for performing the method is described.

There is provided a punching device including: a die member having a plurality of die holes formed therein; a plurality of punch members which are caused to advance into the die holes to punch holes in a member to be punched; an operating member having cam portions formed along a direction intersecting the direction of advancement of the punch members, the operating member being moved along the direction intersecting the direction of advancement of the punch members to cause by a conversion function of the cam portions the punch members to advance into the die holes; and a drive unit for selectively causing advancement of the plurality of punch members by changing the direction of movement of the operating member. In the punching device, each of the cam portions has a straight groove and a cam groove for performing the conversion function, and when the operating member is moved in one of opposite directions, at least one of the cam grooves of the cam portions acts on one of the punch members to selectively cause the same to advance.

A system performs a two-step skew compensation procedure by first correcting for any phase error alignment between a parallel link clock and data signal edges of each data channel, thereby allowing the received data bits to be correctly sampled. Then, a second step is performed to “word-align” the bits into the original format, which is accomplished with a Skew Synchronizing Marker (SSM) byte in a data FIFO of each data channel. The SSM byte is transmitted on each data channel and terminates the skew compensation procedure. When the SSM byte is detected by logic in the data FIFO of each data channel, the data FIFO employs the SSM byte to initialize the read and write pointers to properly align the output data.

A marking device includes a two-dimensional code forming unit converting first identification information into two-dimensional code information in accordance with a predetermined standard and forming a two-dimensional code on an object based on the two-dimensional code information, a two-dimensional code reading unit reading the two-dimensional code and generating second identification information in accordance with the standard, and a determination unit determining whether or not the first identification information matches the second identification information.

The illustrative embodiments provide a method, apparatus, and computer usable program product for generating datamatrix barcodes on parts. A digital datamatrix code associated with a machined part on a numerically controlled machine tool is converted into an x-y drilling pattern contained in a numerically controlled program. A drill cycle associated with a numerically controlled program defines a pattern of dots to be drilled in the machined part to form a dot pattern. A dot pattern is drilled as a series of partially drilled holes on a surface of the machined part to form a datamatrix barcode mark.

The present invention relates to an apparatus and method for driving a PDP (plasma display panel). An image signal processor of the apparatus performs gamma correction and error diffusion processes of input image signals. A quantization error compensator compensates quantization errors with respect to an automatic power control (APC) level of image data output from the image signal processor. An error diffuser sets part of the image data output from the quantization error compensator as display errors and diffuses the display errors to peripheral pixels. A memory control and address driver generates sub-field and address data corresponding to image data that have undergone error diffusion by the error diffuser, and applies the data to the PDP. An APC and sustain / scan pulse generator generates a sub-field arrangement structure according to the APC level, generates control signals based on the generated sub-field arrangement, and applies the control signals to the PDP.

A sequential punch press includes an upper die (10), a lower die (90), and an adjusting device (60) in the upper die. The upper die sequentially includes a punch set (20), a punch pad (30), a punch holder (40), and a stripper (50). A punch (70) is vertically and movably secured in the punch holder and received in the stripper. The adjusting device includes first and second sliding plates (64, 66) respectively having protrusions (65b, 67b), a piston cylinder (68) having a piston rod (682) fixedly connected with the first sliding plate, and a programmable controller for causing the piston rod to slidingly move the first sliding plate. When the first protrusions opposingly abut the second protrusions, the punch can extend beyond the stripper to punch a workpiece. When the first protrusions do not opposingly abut the second protrusions, the punch cannot extend beyond the stripper to punch the workpiece.
