Abstract: A semiconductor photocatalyst includes first and second layers made of first and second materials, respectively. Band gaps of the first and second materials are equal to or smaller than 1.5 eV and 2.5 eV, respectively. A lower electric potential of a conduction band of the second material is disposed on a positive side from the first material. An upper electric potential of a valence band of the second material is disposed on a positive side from the first material and from an oxidation electric potential of water when the first and second layers are bonded to each other in the hetero junction manner. The lower electric potential of the conduction band of the first layer is disposed on a negative side from a reduction electric potential of hydrogen when the first and second layers are bonded to each other in the hetero junction manner.

Abstract: A plurality of synapse determination circuits are provided on a one-to-one basis for a plurality of gate electrodes of a multi-input gate electrode in a neuron element. With respect to first image regions where “1” is repeatedly inputted in correspondence with group information, the synapse determination circuits corresponding to the first image regions are excitatory synapses. With respect to second image regions where “0” is repeatedly inputted in correspondence with the group information, the synapse determination circuits corresponding to the second image regions are inhibitory synapses.
