Latest Patents
Tozawa's latest patents include a heat insulation chamber and a thermostatic chamber, as well as a cryostat. One of his key inventions is a clock signal regenerating circuit designed for use in receivers that handle burst or packet signals in digital radio communications. This innovative circuit allows for the regeneration of a clock signal that can be synchronized with a received signal that has a short preamble. The edge extracting unit within the circuit detects synchronization timing by extracting an edge of the received signal. A reference signal generating unit produces multiple quasi-reference signals with different phases but identical frequencies. The selecting/outputting unit then identifies the quasi-reference signal that is closest to the synchronization timing and outputs it as the clock signal for the receiver. This design ensures that the clock signal can be immediately synchronized with the timing of the received signal.
