Title: Word attribute estimating system
Inventor: NOMURA NAOYUKI
IPC: G06F15/18
Filed: 1995-05-15
Abstract: PURPOSE: To provide a robust analysis function which is efficient, which can deal with all undefined words and whose tuning is facile by registering a character string including a wild card character in a dictionary and statistically processing it without discriminating it from a general word. CONSTITUTION: An analysis means 3 judges the matching of the character string including the wild card character, which is stored in an occurrence probability storage means, with an input character string when the word attribute of the input character string cannot be decided by using the dictionary 1. When they match with each other, the character string and/or the occurrence probability of the word attribute, which are stored in the occurrence probability storage means 2, are read out and they are outputted to a word attribute estimation means 5 together with information stored in the dictionary 1.  The word attribute estimation means 5 receiving the candidate of the word attribute and the occurrence probability selects the word attribute having the occurrence of more than a prescribed number, makes it a pair with the corresponding input character string and sets it to be the output of a text analysis device.

When such abnormal state continues for a certain time, the alarm signal E is outputted from the alarm means D. Thereby, it is possible to preclude the intrusion of a stranger by informing abnormality to a prescribed place by the signal or threatening the strange person.

Title: Semiconductor memory
Inventor: TATEWAKI YASUHIKO
IPC: G11C16/06
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory which can realize reading data at high speed. SOLUTION: After word line selecting signals WLS0, WLS1 are latched by latch circuits L0, L1, transfer gates TG0, TG1 are turned off. When a word line WL00 is selected, voltage supplied to the latch circuit L0 is shifted to a desired level, and desired voltage is supplied to the word line WL00 from a word line driver D0. Thereby, as a pre-decoding signal RAL is inputted to inverters B0, B1 and transmitted to word line drivers D0, D1 between a potential Vcc and a potential GND, parasitic capacity added to the pre-decoding signal RAL0 is reduced.
