Title: Dropout compensating circuit
Inventor: MURAMOTO TOMOTAKA
IPC: H04N5/94
Filed: 1987-05-16
Abstract: PURPOSE:To effectively compensate a dropout, by detecting the basic cycle of signals immediately before or after the dropout takes place and replacing the dropout part with the signals before or after the dropout by an integral number of times of the basic cycle. CONSTITUTION:Reproduced audio signals are amplified by a preamplifier 12 and impressed upon an FM demodulator 14. Then the audio signals are converted into digital signals by an A/D converter 16 and stored in a memory 18. An autocorrelation detecting circuit 28 detects the basic cycle of the data accumulated in the memory 18 from the data. On the other hand, when a dropout detecting circuit 26 detects a dropout from the output of the preamplifier 12 and outputs a detect signal, a memory controlling circuit 30 replaces the dropout with preceding signals by an integral number of times of the basic cycle detected by the autocorrelation detecting circuit 28 for a period a little longer than the dropout period, and thus, the dropout is effectively compensated.

Title: Displacement measuring device
Inventor: MURAKAMI FUMIO
IPC: G01B11/00
Filed: 1992-04-14
Abstract: PURPOSE:To sharply reduce the measurement error even when a reflected light pattern is fluctuated by arranging two groups of lenses so that the focal positions of the lenses coincide, and inserting a rectangular aperture limiting the reflected light from the moving direction of a light spot at the focal position. CONSTITUTION:A displacement measuring device projects a fine light beam 2 to a measurement object 3, guides the reflected light from a light spot on the measurement object 3 to a position detector 8 via an optical system, converges it on the position detector 8, and measures the distance to the measurement object 3 and displacement. The optical system is arranged so that the focal positions of the first lens 61 and the second lens 62 coincide, and a rectangular aperture 63 is provided at the focal position. A point N is located off from the image forming conditions, and light is converged at a point N' apart from the position detector 8. Most of the light passing through the optical system proceeds in parallel with the optical axis, and the light is fed into the position detector 8 after passing through the point N'. When the rectangular aperture 63 is inserted, only the constituent parallel with the optical axis within the reflected light pattern from the light point 4 is extracted, thus the measurement error can be sharply reduced even when reflected light pattern of the light point 4 is fluctuated due to the size of the light point 4 and the material and surface treatment of the measurement object 3.

Title: Paper feeder for recorder
Inventor: UNO NOBUYUKI
IPC: B41J15/16
Filed: 1982-07-08
Abstract: PURPOSE:To secure a given accuracy of paper feeding by a method in which papers are supplied by normally turning a platen and then reversely turning the platen, while the paper is closely contacted with the platen, and the slackening of the paper is removed. CONSTITUTION:A platen 1 is turned by application of a slight excess of pulse number beyond a required pulse number to a paper feeding motor M1 and a paper P is fed. Afterwards, an excessive puls number is applied in opposite polarity to the motor M1 to reversely turn the platen 1. A clutch 8 is internally provided to an arm 7 supporting both ends of the support shaft 6 of the roller 5 to prevent the reverse turning of the support shaft 6 and the upper roller 5, and thereby the upper roller 5 becomes stopped. The sliding friction force of the upper roller 5 is made greater than that of the platen 1. Accordingly, even when the platen 1 is reversely turned, the upper roller 5 is in stopped state and the tip of the paper P is stopped by the upper roller 5. On the other hand, since the lower roller 4 reversely turns in the wake of the platen 1, the rear end of the paper P is sent toward the opposite direction together with the lower roller 4 and the platen 1, and the slackening of the paper P is thus removed.
