  • Neuron unit, neural network and signal processing method
    Patent number: 5167006
    Abstract: A neuron unit processes a plurality of input signals and outputs an output signal which is indicative of a result of the processing. The neuron unit includes input lines for receiving the input signals, a forward process part including a supplying part for supplying weight functions and an operation part for carrying out an operation on each of the input signals using one of the weight functions and for outputting the output signal, and a self-learning part including a generating part for generating new weight functions based on errors between the output signal of the forward process part and teaching signals and a varying part for varying the weight functions supplied by the supplying part of the forward process part to the new weight functions generated by the generating part.

  • Semiconductor diffusion type force sensing apparatus
    Patent number: 4884051
    Abstract: A semiconductor diffusion type force sensing apparatus includes a plate-like semiconductor substrate formed by a single crystal material, and a plurality of sensing elements each constituted by a substantially rectangular impurity-diffused region formed in the semiconductor substrate. The sensing elements have an electric resistance variable in accordance with a deformation thereof due to an external force exerted on the semiconductor substrate. The sensing elements are arranged in a direction in which a longitudinal direction of each of the sensing elements coincides with a crystal orientation of the semiconductor substrate having an external value of a longitudinal piezoresistance coefficient of the impurity-diffused region.
