    摘要： A liquid jet recording head includes a liquid path member having a plurality of liquid flow paths, each of the liquid flow paths being filled with a recording liquid, an orifice being formed at an end of each of the liquid flow paths, and a heater base member having a plurality of heater members and a plurality of radiator members. The heater base member is connected to the liquid path member, each of the heater members having a heater portion, the heater portion generating heat in accordance with a power supplied to it. Each of the radiator members is thermally coupled to the heater portion of one of the heater members so that the amount of heat transmitted from the heater portion to the recording liquid on the heater portion changes in a predetermined direction. When a power is supplied to the heater portion, a bubble is generated in the recording liquid and located at an area on the heater portion, the area having a size corresponding to the power supplied to the heater portion, the bubble causing a recording liquid droplet to be jetted from the orifice.

    摘要： A method and apparatus are disclosed that modify [ies] and generalize [s] the use in artificial neural networks of the error backpropagation algorithm. Each neuron unit first divides a plurality of weighted inputs into more than one group, then sums up weighted inputs in each group to provide each group's intermediate outputs, and finally processes the intermediate outputs to produce an output of the neuron unit. Since the method uses, when modifying each weight, a partial differential coefficient generated by partially-differentiating the output of the neuron unit by each weighted input, the weight can be properly modified even if the output of a neuron unit as a function of intermediate outputs has a plurality of variables corresponding to the number of groups. Since the conventional method uses only one differential coefficient, that is, the differential coefficient of the output of a neuron unit differentiated by the sum of all weighted inputs in a neuron unit, for all weights in a neuron unit, it may be said that the method according to the present invention generalizes the conventional method. The present invention is especially useful for pulse density neural networks which express data as an ON-bit density of a bit string.
