Title: Driving of ink jet head
Inventor: YASUHARA MASATOSHI
IPC: B41J2/055
Filed: 1990-03-02
Abstract: PURPOSE:To enable an ink drop to be jetted, to accelerate jetting speed of the ink drop and to lessen a diameter of the ink drop even by driving at low voltage by a method wherein ink is jetted by executing reduction of pressure in an ink pressurizing chamber on a nozzle outlet side and application of pressure to the ink pressurizing chamber on an ink supply side at a certain time lag to jet the ink. CONSTITUTION:Printing voltage (b) is applied to a piezoelectric element (2) 4 and applied voltage shifted in time therefrom is applied to a piezoelectric element (1) 3. That is, pressure in a nozzle is reduced by the applied voltage (b) applied to the piezoelectric element (2) 4 and a meniscus is drawn in. When the meniscus returns to an original position, a pressure wave generated by the applied voltage (a) applied to the piezoelectric element (1) 3 is accelerated by arrival of the meniscus, and the ink drop is jetted. Consequently, the ink drop can be jetted even by driving at low voltage.

Title: Hierarchy type information processing system
Inventor: ITO TAKAYUKI
IPC: G06F9/44
Filed: 1987-03-07
Abstract: PURPOSE:To obtain a superior permissive capacity with respect to the expansion and the contraction of a pattern in a time direction by maintaining the output of the cell of a layer having a characteristic extracting ability so as to maintain the upper layer for the longer time, and performing a learning so as to perform the learning for the upper layer at the longer interval. CONSTITUTION:The layer D, on which delaying elements are arrayed, converts the time space pattern of a definite time into a two dimensional space pattern. The layer P is the layer, which catches the time space pattern of the narrow area of a one layer lower layer, as a spatial characteristic, and is constituted of a two dimensionally arrayed cell surface. The layer T has an ability to permit the spatial position slip of the reaction of the layer P, and at the same time, maintains the reaction of the layer P for a definite time. The characteristic of the reaction of the layer P is determined by the learning, and the learning is carried forward by turns from the layer near to an input, by the algorithm of a maximum value detection type. The learning is schemed so that a teacher signal generating cell controls a learning time, and the said cell receives the input from the layer T, one step before, and generates a teacher signal at the vicinity of the middle point of the duration time of the layer T.

Title: System for extracting japanese key word text
Inventor: KOBAYASHI TOSHIHIKO
IPC: G06F17/30
Filed: 1987-03-05
Abstract: PURPOSE:To extract a key word in a consistent extraction method with no intervention of man power by deleting such character strings that cannot give features of a text with reference to a non-key word file and extracting the character strings having high emerging frequency table. CONSTITUTION:When a Japanese word text data is converted into codes, a character extracting means 15 extracts a character string containing at least KANJI (Chinese character) or KATAKANA (square form of Japanese syllabary) out of a text based on a range of KANJI codes or KATAKANA codes. Then a key word extracting means 18 decides from the information on a non-key word file 16 whether said extracted character string is generally improper or not to give features to a text. Then the emerging frequency of a character string which is not decided improper is obtained from a character string emerging frequency table 17. Then the character string having a high emerging frequency is decided as a key word of the text. Thus it is possible to extract a key word of the Japanese word text data with no intervention of man power.
