Filed: 1986-05-19
Abstract: PURPOSE:To expand a jump range only by an actuator and to shorten the average access time of an optical disk device by permitting the position sensor of an optical head to detect the track jump available range of the actuator. CONSTITUTION:A control circuit 5 calculates and transmits the distance that an optical axis moves from its present position to a target track. The value is D/A-converted 6 and transmitted to an adder 7. On the other hand, the actuator 1 transmits the output of the position sensor to the adder 7. In such a case, variation of the output of the position sensor when the actuator shifts the optical axis by one track, and the variation of the output value when the actuator 1 shifts a conversion circuit 6 by one track area the same. At the same time, polarity code inverted according to whether the optical axis shifts to the inner periphery of the optical disk or to its outer periphery are also associated with said variation. Consequently, the addition output shows the distance that the optical axis shifts from the neutral point of the actuator.

Title: Electronic interpreter
Inventor: NAKANO HARUMI
IPC: G06F17/28
Filed: 1982-07-05
Abstract: PURPOSE:To realize the interpretation for the varied forms of words and at the same time to increase the searching speed, by comparing the fed words from the side of the ending of wirds. CONSTITUTION:When a word is searched in a dictionary memory, a comparison is carried out at and after the characters of the ending of words. Thus the ending of words having the regular conjugation is detected, and the part of the ending of words having the regular conjugation is excluded from the supplied words. Thus the basic word is obtained. In such way, the interpretation is possible without storing the varied forms of words into a memory. Furthermore the ending of words having the regular conjugation can be detected in an easy and accurate way by starting a comparison from the ending of words for the supplied words. Thus the processing speed can be increased for the interpretation.
