  • Patent number: 6556701
    Abstract: Disclosed are a method of and an apparatus for extracting a dotted line from an binary image of a document, and a storage medium thereof. The isolated points are extracted from the binary image. The isolated points configuring a candidate of the dotted line are extracted based on a positional relationship between the extracted isolated points. A validity of the isolated points configuring the candidate of the dotted line is checked. The dotted line from a positional relationship between groups of the extracted isolated points of the candidate of the dotted line. The dotted line can be thereby precisely extracted even if some isolated points are lost due to an. under-density of the image etc.

  • Patent number: 6550318
    Abstract: An abnormality diagnosis apparatus for performing a leak check of an evaporative fuel processing system which includes a fuel tank, a canister for storing evaporative fuel generated in the fuel tank, a purging passage for connecting the canister to an intake system of an internal combustion engine, and a purge control valve provided in the purging passage. A process of reducing the pressure in the evaporative fuel processing system is executed with a limited flow rate of gases passing through the purge control valve when performing the leak check in an idling condition of the engine. The limited flow rate is set to a value equal to or smaller than a predetermined flow rate which is smaller than the maximum flow rate applied to the leak check performed in operating conditions other than the idling condition. The leak check is performed on the basis of a change in the pressure in the evaporative fuel processing system after the pressure reduction process.

  • Patent number: 6552956
    Abstract: A non-volatile semiconductor memory device 1 includes a first address counter 6 and a second address counter 8. The non-volatile semiconductor memory device 1 further includes two control counters, namely, a first control counter 2 and a second control counter 4 for controlling counter values of the first address counter 6 and the second address counter 8, respectively. Thereby, an output from the first control counter 2 and that from the second control counter 4 are inputted to the first address counter 6 and the second address counter 8, respectively to control the number of addresses to be outputted. Since the two pairs of address counter and control counter are provided, the structure of the two-paired counters enables the non-volatile semiconductor circuit device 1 to control the number of addresses to be used corresponding to various operation modes such as readout, write (program), erase and the like, and to allocate address values to the addresses for use sequentially.

  • Patent number: 6552957
    Abstract: A timing signal generator receives a plurality of control signals in synchronization with a clock signal, and generates a timing signal according to a combination of the control signals. A delay circuit delays an input signal received asynchronously to the clock signal by a predetermined time. A receiving circuit receives the input signal which is delayed by the delay circuit, in synchronization not with the clock signal but with the timing signal. Namely, the receiving circuit operates asynchronously to the clock signal, and receives only necessary input signals for the semiconductor integrated circuit. This lowers operation frequency of the receiving circuit, thereby reducing power consumption. The number of the circuits to be operated in synchronization with the clock signal can be reduced, by which reduces standby current. An increase in the standby current is gradual even when frequency of the clock signal goes high.
