| Number | Title | Issue Date |
| 6381261 | Random pulse type radar apparatus A random pulse type radar apparatus sends out as an output signal a spectrum spread radio wave including a pseudo random signal-less period and receives echoes in this signal-less period to thereby significantly reduce transmission peak power. The random ... | 04/30/2002 |
| 5987491 | General purpose charge mode analog operation circuit A general purpose charge mode, analog operation circuit provides adder, multiplier, divider (D/A converter) and other functions using a single hardware configuration to be used in different modes. A two-dimensional lattice circuit including electrical cha... | 11/16/1999 |
| 5936567 | Parallel charge signal delivery system, and filtering AD converter using the same A data supply method for performing exact operations by a number of operation units receiving a single signal as input is proposed; and a composition of a system provided with both the filter function and the AD conversion function using the same is also ... | 08/10/1999 |
| 5887025 | Matched filter acting in charge domain A charge mode operation circuit dedicated to detect the correlation between analog input signal and digital code, and for realizing by "RAKE method" the path diversity reception from the correlation data obtained using the same. The circuit utilizes an an... | 03/23/1999 |
| 5701260 | Multiplier using charge transfer device A multiplier using a charge transfer device, broadly applicable to analog signal processing, digital-to-analog (D/A) conversion, or parallel image processing. The multiplier includes a charge transfer device with at least 8 independent potential wells arr... | 12/23/1997 |
| 5634067 | Systolic array processor A systolic array processor is provided which is adapted to virtually constitute a number of analog type pipelining processors which operate in a parallel manner on an analog type shift register array such as a CCD or the like.
