Inventor: MINEURA TOSHIMI
IPC: B21C47/00
Filed: 1980-02-26
Abstract: PURPOSE: To make stable operation possible despite the occurrence of any slip between the press rollers attached with speed detectors of steel strip and a steel strip by obtaining the coil diameters on the uncoiler and coiler side from the ratios of the respective revolutional numbers of the uncoiler and coiler and controlling said ratios.  
     CONSTITUTION: A steel strip 1 is uncoiled from an uncoiler 2 and is coiled by a coiler 3. The machines 2, 3 are driven by motors 4, 5 respectively, and the tension and steed of the steel strip are made constant by current and speed control devices 6, 7. Here, the revolutional numbers of the machines 2, 3 are detected by detectors 13, 14, and the ratios thereof are operated by a device 15. From these ratios, the coil diameters D 1 , D 2  on the machine 2, 3 side are operated by a device 16. A speed reference generator 9 applies the rotating speed reference value of the machine 5 to the device 7 by using the diameter D 2  obtained by the device 16. The device 7 controls the rotating speed of the detector 12 in such a manner that it coincides with said value. Also, the device 6 controls the current of the machine 4 in such a manner that it coincides with the reference value from a current reference generator 8; at the same time, it controls the field current by using the diameter D 1  in such a manner that the field flux ϕ of the machine 4 assumes D 1 ∝ϕ.

Abstract: PROBLEM TO BE SOLVED: To suppress the generation of a carrier having the slow moving speed on a dividing line by dividing diffracted rays coming from adjacent regions into the lights having two peaks and converging each peak of the lights to two regions separated by the dividing line of a photodetector. SOLUTION: The diffracted rays from the region (a) of a hologram are arranged so as to converge around the dividing line 13 of the regions A, B, then the diffracted rays from the region (c) of the hologram are converged around a center of the region C of the photodetector. The regions E, F of the photodetector are used for receiving side beams of three beams for tracking. For avoiding the light convergence onto the dividing line of the photodetector at this stage, a dividing line 11 is provided, by which a phase of the diffraction grating period of the hologram is changed by 180 deg.. Further, by providing a specific light shielding means on the dividing line 13 of the light converging regions A and B, the generation of the carrier having the low moving speed at the light detecting point under this dividing line 13 is reduced.

IPC: G09F9/30
Filed: 1992-02-07
Abstract: PURPOSE:To improve the display characteristics of the active matrix type liquid crystal display device by suppressing the generation of parasitic capacity. CONSTITUTION:Active matrix substrate side light shield films 106 and 107 do not overlap with a gate electric conductor 102 as a scanning line, so no parasitic capacity is generated between the active matrix substrate side light shield films 106 and 107 and gate electric conductor 102, which does not overlap with a picture element electrode 110, so no parasitic capacity is generated between the gate electric conductor 102 and picture element electrode 110 either. A counter substrate side light shield film is formed covering the gaps between the active matrix substrate side light shield film 106 and 107 and gate electric conductor 102 which do not overlap with each other, so light leaking from the gaps can be cut off. The counter substrate light shield film needs to shield only the gaps, so the aperture ratio is not decreased. The active matrix substrate side light shield film 106 may function as a drain electrode or the drain electrode may be formed separately.

Filed: 1987-02-03
Abstract: PURPOSE:To widen a signal band, and also, to improve an S/N by providing a circuit for bringing an output from an output side transistor, to a positive feedback to an input side transistor through a capacity element. CONSTITUTION:A reproducing signal from a video head 1 is supplied to the base of a transistor (Tr) X1 through a rotary transformer 2 and a capacitor 3, amplified by Trs X1, X2 for constituting a cascode amplifier, and fetched from an output terminal 6 through an inversion amplifying Tr X3 and a capacitor 5. In this case, a collector output of the Tr X3 is brought to a positive feedback to the base of the Tr X1 through a capacitor 4, by which the capacity generated by a Miller effect and the input capacity between the base of the Tr X1 and a ground are negated and lowered. Therefore, a resonance frequency moves to a high frequency, and a signal band is widened. In this state, when that which has a small base expanse is used for the Tr X1, the S/N can be improved. In this case, the input capacity becomes large, but the input capacity is reduced by an operation of the capacitor 4.

Title: Rotary head type recording and reproducing device
Inventor: TAKIMOTO HIROYUKI
IPC: G11B5/588
Filed: 1983-02-14
Abstract: PURPOSE:To record the signal accurately at a prescribed position on a recording medium by compensating the position shift of a head which is produced in a record mode by the secular change of a mobile member. CONSTITUTION:Variable resistances VR11 and VR12 are adjusted while the head height of a drum is observed through a microscope, and therefore the head height of its original state can be set at a proper level. In a reproduction mode, switches SW1 and SW14 are connected to the terminals shown at the P side. Then the control signal, etc. serving as the voltage applied to a bimorph plate needed for tracking control which is required in the reproduction mode are applied to driving circuits 46 and 47 from a reproduction control circuit 50. This applied voltage is detected to control accurately the height of the head in a video record mode. Thus it is possible to compensate the position shift of the head and to record the signal more accurately at a prescribed position on a recording medium.
