Title: Magnetic tape reproducing device
Inventor: ARAI KAZUO
IPC: G11B15/467
Filed: 1988-03-09
Abstract: PURPOSE:To securely read out a bit of tape positional information on a magnetic tape by making a speed component of a head in the direction of a track constant, regardless of the traveling speed of the magnetic tape. CONSTITUTION:The traveling speed of the magnetic tape 1 is detected by reel speed detectors 2a and 2b fitted to reels 9a and 9b and a tape speed calculating means 5, and a rotary cylinder 3 is set in such an r.p.m. that the speed components of the heads 2a and 2b in the direction of the track under the above speed of the magnetic tape are constant, and is controlled with this r.p.m. Consequently, even when the speed of the magnetic tape 1 is changed from low speed to high speed, the speed components of the heads 2a and 2b in the direction of the track are kept constant, and the tape positional information on the magnetic tape 1 is always securely read out. By this method, even when the magnetic tape 1 is changed at once from a slow speed traveling state to a high speed traveling state or vice versa, the tape positional information on the magnetic tape can securely be read out in the process of acceleration or deceleration of this tape speed.

Abstract: PURPOSE:To eliminate chances to give an uncomfortable feeling to customers because the product of a displayed unit price and an oil feed quantity becomes a total price by a method wherein a control unit, for which a unit price is lowered in proportion to the increase of an oil feed quantity, and the unit price and a total price are displayed after the completion of an oil feeding, is provided. CONSTITUTION:On an oil feed equipment 1, a control unit 11, for which a unit price is lowered in proportion to the increase of an oil feed quantity, and the unit price and a total price are displayed after the completion of the oil feeding, is provided. Therefore, in proportion as an oil feed quantity increases, the unit price is discounted, but the unit price and the total price are displayed only after the oil feed work is completed, and comparison with other customers is hard to do. For this reason, an uncomfortable feeling is not given to the customer. Also, since a total price is always given by multiplying an oil feed quantity by a unit price, a reliable feeling can be given to customers.

Title: Mechanical translation system
Inventor: HIROSE SHIGERU
IPC: G06F17/28
Filed: 1984-03-23
Abstract: PURPOSE:To improve the probability of production of a correct sentence using a target language and to enable even a user having no knowledge of the target language to use a mechanical translation system, by providing a meaning mark processing part, a meaning relation mark processing part and a concept structure processing part. CONSTITUTION:When a sentence of a language to be translated is fed to a subject language input part 8, a word dividing part 9 decomposes the sentence into words while referring to a dictionary file 6. A meaning mark processing part 10 obtains the meaning marks corresponding to each word, and a meaning relation mark processing part 11 discriminates the relation among meaning marks and delivers the meaning relation marks. A concept structure processing part 12 produces a meaning network of the language to be translated from the output of the part 11 and performs the concept conversion into a meaning network of a target language to produce a sentence of the target language through a target language producing part 13. In case the translation fails in this process, the procedure proceeds to a concept structure designating input mode of a user. Thus the probability of afilure is reduced for translation and even a user having no knowledge of the target language can use easily this mechanical interpretation system.

Title: Significant signal amplifying circuit
Inventor: SHIRAGASAWA TSUYOSHI
IPC: H03F3/34
Filed: 1988-03-09
Abstract: PURPOSE:To follow up even an original signal including a high frequency component with a margin by compressing a significant signal in a level higher than a first preliminarily determined value out of the original signal and expanding a significant signal in a level lower than a second preliminarily determined value before sampling and holding. CONSTITUTION:The original signal has a DC offset voltage V and includes significant signals (spike noise) N1 and N2 whose levels are higher than those of periodical significant signals P1 and P2 to be detected. This original signal has the offset voltage component cut when passing an HPL 11. Signals in higher levels are compressed and signals in lower levels are expanded by a nonlinear amplifier 12. The output signal of the nonlinear amplifier 12 is sampled and held at the timing of a sampling signal by a sample and hold circuit 13, and only a signal having a low frequency is inputted to a linear amplifier 14. Thus, even the original signal having a high frequency is sufficiently followed up because the amplification factor of the linear amplifier 14 is increased and the switching noise does not occur.
