Title: Compensation system for distortion in transmission line
Inventor: SANPEI MASAICHI
IPC: H04L7/04
Filed: 1988-02-02
Abstract: PURPOSE:To improve the utilizing efficiency of a frequency by detecting a distortion of a frame symbol through the transmission line, interpolating the time series of the said distortion, estimating the other distortion in the transmission line and compensating the distortion in a received base band signal. CONSTITUTION:A transmission section sends a known symbol once for each N-set of information symbols (N is a natural number) for the use with measuring transmission line distortion. A frame detection section 16 of a reception section detects the timing of a frame symbol and a transmission line estimate section 17 estimates the transmission line distortion from a received base band signal in the frame timing. Then an estimate C(t) of the transmission line distortion obtained in this way is transferred to a transmission line distortion compensation section 18, where the value is used to compensate the transmission line distortion with respect to an input u(t). Then the base band signal s(t) whose transmission line distortion is compensated and threshold level information are transferred to a decoding section 19, a transmission symbol is reproduced to reproduce the k-bit information included in the symbol. The information is converted into serial information by a parallel/serial conversion section 20 and outputted as the reproduced data. Thus, the utilizing efficiency of the frequency is attained.

Title: Both side controller
Inventor: KOMORI SHIGEHIRO
IPC: B65H3/44
Filed: 1982-02-13
Abstract: PURPOSE:To make the prevention of idle operation possible by controlling both side copying according to the detection signals of the detection means for copying sheets installed in prescribed positions. CONSTITUTION:When a copying sheet 17 exists in the cassette 16 of the 1st containing part, a photodetector 200 detects this, and the sheet is carried out, thence the one side image formed on a photosensitive drum 1 is transferred. Thence, when the trailing end of the sheet 17 is detected with a photodetector 29, discharge rollers 22 are controlled to revolve reversely, so that the sheet 17 is contained in the 2nd containing part 671 without discharged. As far as the leading end of the stacked sheets 17 is detected with a photodetector 134, the transfer of the two side images on these sheets 17 is accomplished in the same way. Since the reiterative copying operations are not controlled by the predetermined copying times, the idle operation is prevented despite overlapped feeding of the sheets 17 or the like.

Title: Inclined character recognizing system
Inventor: TAMIYA DAIJI
IPC: G06K9/34
Filed: 1988-02-02
Abstract: PURPOSE:To surely recognize segment characters even when the characters are inclined characters by a contour scanning method by scanning scanning lines lines for the segment characters in vertical and horizontal directions so that the scanning directions can be parallel with rectangular coordinates inclined by a detected inclination angle for reading rectangular coordinates. CONSTITUTION:In the case of the inclined characters, a character string extracting part 16 retrieves line data 26 adjacent to the inclined character string, detects the inclination theta of the characters from the line data 26, and stores the detected inclination theta in a character string data table 18. Therefore, an edge table preparing part 22 can know the inclination theta of the characters from the character string data table 18, and the edge table preparing part 22 prepares an edge table by scanning the scanning lines by the contour scanning method in the vertical and horizontal directions so that the scanning directions can be parallel with the rectangular coordinates inclined at the inclination thetafor the reading rectangular coordinates. Consequently, even when the characters are the inclined characters, the same edge table as the one for the characters having no inclination can be prepared. Thus, even the inclined characters can be surely recognized.

Title: Rear wheel suspension device for rear wheel steering vehicle
Inventor: EDAHIRO TAKESHI
IPC: B60G3/20
Filed: 1989-01-30
Abstract: PURPOSE:To aim at the compaction of a rear wheel steering gear by connecting a shock absorber to a wheel support in such a way that the reaction axis has a three- dimensional point of intersection with the virtual king pin axis of a rear wheel. CONSTITUTION:The reaction axis l1 of a shock absorber 84 is connected to a wheel support 32R (or 32L) in such a way as to have a three-dimensional point of intersection with the virtual king pin axis l2 of a rear wheel 3R (or 3L) in the initial state of a vehicle. Accordingly, at the bumping and rebounding time of the rear wheel 3R, the reaction force of the shock absorber 84 (the damping force of a damper 91 and the spring reaction of a coil spring) acts upon the support 32R in such a way as to intersect the virtual king pin axis l2 as the steering rotation center axis of the rear wheel. This reaction force thus prevents the rear wheel 3R from being steered integrally with the support 32R and thereby prevents the rear wheel steering from adverse effect caused by a rear wheel steering gear 4. Accordingly, the neutral position energizing force (spring force) just enough to overcome the lateral force at the time of cornering is sufficient for a centering spring in a neutral position reset means 22.
