  • Patent number: 6618280
    Abstract: An associative memory includes an array of CAM cells each having a transistor indicating a result from comparing a stored bit with a reference bit. The transistors are connected in serial in each row of the array to form a NAND circuit producing a signal representing that the bits stored in all the cells in the row are consistent with the reference bits or otherwise that the cell at the LSB of the row stores a bit consistent with a reference bit. Each column of the array includes a logic circuit for masking the bits except those continuous from the MSB toward the LSB which correspond to the bits of a word having the most bits continuous from the MSB toward the LSB and consistent with the bits of the reference word among the stored words. The NAND circuit in a row of the cells storing a word having the most bits continuous from the MSB toward the LSB and consistent with the corresponding bits of a reference word develops a signal representing the longest coincidence data detected.

  • Patent number: 6328690
    Abstract: An air feeding device for endoscope system includes an air compressor that compresses air and feeds the air in a sealed space, and a pressure sensor that detects air pressure in the sealed space. Further, a pressure setting device and a pressure controller are provided. The pressure setting device is used for setting a pressure value to be achieved in the sealed space, and the pressure controller turns ON and OFF the compressor in accordance with the air pressure detected by the pressure sensor and the pressure value set by the pressure setting device. The air feeding device has a main valve. An inlet of the main valve is connected to the sealed space, and an outlet of the main valve is connected to an outlet of the air feeding device. By opening the main valve, the air enclosed in the sealed space is discharged from the outlet to strike an object at a certain pressure.
