Patent JP-H07170171-A (JP)
Title: Semiconductor integrated circuit device
Inventor: YAMAGUCHI SEIJI
IPC: H03K19/173
Filed: 1993-12-14
Abstract: PURPOSE:To change a drive capability into programmable depending on the operating condition by applying on/off setting independently to a gate of n-sets of N-channel MOS FETs and a gate of n-sets of P-channel MOS FETs respectively. CONSTITUTION:When the drive capability of an output node 6 is set minimum, an L level is given to Gn2, Gn3 and an H level is given to Gp2, Gp3 to make N-channel MOSFETs N2, N3 and P-channel MOSFETs P2, P3 nonconductive. On the other hand, when the drive capability of the output node is set maximum, either of the TRs N1-N3 and the P1-P3 are conductive by selecting the conditions of Gn1=Gn2=Gn3 and Gp1=Gp2=Gp3. Thus, the drive capability is revised in an optimum state depending on an external load condition of the node 6 thereby reducing the power consumption.

Title: Device for recognizing between lines
Inventor: IKEDA MASARU
IPC: B41J21/16
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a device for recognizing between lines correctly recognizing between lines of a sentence by generating a histogram of character information represented as a bit map and recognizing lower frequency of occurrence of bits in the histogram. SOLUTION: Original image data 4000 from an OCR are given to a data input output section 2100, in which the data are converted into a bit map. A histogram generating section 2310 generates a histogram based on the bit map to evaluate the histogram to evaluate the presence of between lines in an original. When a sufficiently high contrast is not obtained, the bit map is rotated by a prescribed angle each and then the histogram is generated again. When the contrast is evaluated to be high, a histogram processing section 2320 conducts correction processing of the bit map, and after a series of processing, processed image data 50000 are sent to an optical character recognizer OCR.
