Patent JP-H04181311-A (JP)
Title: Microcomputer
Inventor: TAKAHASHI YOICHI
IPC: G06F1/28
Filed: 1990-11-15
Abstract: PURPOSE:To prevent a product from being broken and malfunctioning by automatically detecting and evading the short-circuit state of an input/output terminal. CONSTITUTION:This microcomputer has a function which detects a short circuit by utilizing a voltage drop caused by a current flowing through the short circuit of the input/output terminals and then inhibits an output state. Assuming that the input/output terminal 100 short-circuits with a power source potential VDD or a higher-potential place, a large current flows through protection resistances 101 and 104 and a transistor(TR) 107 to raise the potential at a point A from a GND level to a higher potential. Then mu becomes active (Hi) and the potential at the point A is read by a 4NAND gate 106, whose dimension is so determined that the gate falls to Low only when the short-circuit current flows exceeding a target value. At the timing where phi3 is active, the signal of the 4NAND gate 106 for reading the level at the point A is latched by a register 111, but when the short-circuit current is large, the Low is latched to cut off an output buffer 107. Consequently, even if the input/output terminal is short-circuited, malfunction and a breakage accident can be precluded.

Title: Character recognition system by neural network
Inventor: SAGA KAZUSHIGE
IPC: G06K9/66
Filed: 1992-11-20
Abstract: PURPOSE:To improve a recognition rate by further categorizing a same character kind corresponding to the features of characters and thereby performing recognition. CONSTITUTION:Character picture data are supplied to the input unit 11 of a neural network 1 and recognized results are outputted from output units 12. The output units 12 are provided in plural numbers for the character kind to be recognized and learning is performed so that the different output units react when the features are different even for the same character kind. Thus, even when the data of the same character kind are inputted at the time of the recognition, when the features of the characters are different due to the difference of fonts or the like, the different output units react. Since the output units 12 are provided in plural numbers for the character kind to be recognized, the same character kind provided with the different features is not forcedly recognized by one output unit and the recognition rate can be improved. Also, the same character kind can be categorized by using a random network 7.
