Filed: 1979-03-03
Abstract: PURPOSE:To realize the simultaneous acquisition of both the video and aural signals by giving the time axial compression to the aural signal for the simultaneous recording and reproducing with the still picture image. CONSTITUTION:The time axial compression is given via time axial compressor 12 to the signal of aural signal source 10 in order to store the signal within the recording time of the video signal. This compressing action is attained by increasing the reading speed more than the writing speed by means of the memory. This compression signal is compounded at compounding circuit 14 via FM modulator 13 along with the video signal of FM modulator 11 and then shaped into nearly the rectangular wave through limiter 15 to be applied to optical modulator 2. A number of video signals of the still picture and aural signals with the time axial compression given are prepared previously to be transmitted continuously after the synchronization is once secured at first. Thus the both signals of many frames are recorded continuously. In ths case of the reproduction, the wiring is given into the memory of the time axial expander and then the reading is given in a lower speed than the writing velocity to perform the time expansion. And then the demodulation is carried out through the demodulator.

Filed: 1978-03-07
Abstract: PURPOSE:To shorten the fault recovery time for the fault retrieving system through the automatic detection of the faulty area by detaching temporarily and selectively the transmission device of the lower place by the central control unit when the carrier fault information signal is received from a transmission device. CONSTITUTION:Transmission device STi(i=1-k) monitors 6 the carrier fault and then informs the carrier fault, if occurs, to central control unit ST0 via transmission circuit part 4, and at the same time receives 3 the order from unit ST0 to reset FF9 and then switching off by-pass relay 2 to detach it from transmission line 1. Furthermore, common control part 5 is detached from line 1 through the self- control in case the carrier fault continues for more than the fixed time. Here, unit ST0, when receiving the carrier fault information from unit STi, detaches temporarily and selectively the transmission device which is located at the lower place of STi from the transmission line based on the detaching order, thus carrying out the automatic faulty area. As a result, the faulty area can be detected quickly at the remote place to eliminate the fault quickly, thus shortening the fault recovery time of the system.

Abstract: PURPOSE:To eliminate the necessity of demounting an optical fiber core at each time when microscope observation is performed, by allowing a top-edge chuck to be positioned directly over a grindstone or the object glass cylinder of the microscope by revolving an optical fiber holder on a frame. CONSTITUTION:Polishing is performed by using a grindstone 26 having the highest roughness and mounting a core 10 having a fiber 14 onto a chuck 36. At this time, the force of a compression spring 40 acts to press the core 10 onto the grindstone 26. Afterward, polishing is performed by replacing the grindstone 26 having the finer grains and using a buffering device, and in the course a holder 30 is turned leftward and shifted onto a board 68, and a microscope 84 is turned a little around a pivot screw 106, and the edge surface of the core 10 is observed by adjusting the visual field. Polishing is completed when the stripe formed in cutting the edge surface of the fiber 14 is made gradually thinner. The adjustment of visual field is not necessary on and after the second observation. Thus, the necessity of demounting the core from a polishing machine for observing the polishing condition is eliminated.

Filed: 1992-01-17
Abstract: PURPOSE:To eliminate the fluctuation of an air pressure until a vehicle reaches a second car speed after braking is started so as to perform accurate measurement by maintaining a solenoid valve in an energized state until the vehicle reaches the second car speed from a first car speed after the braking is started based on a regulated air pressure. CONSTITUTION:The antilock brake system (ABS) of a vehicle is discriminated by measuring the decelerating time from, for example, a 40-km/h car speed to a 20-km/h car speed (C-car speed) and a coefficient of viscosity (K-value) is measured and discriminated while air pressures respectively regulated in corresponding to a low- and high-mu road ABS testing roads are supplied to the brake circuit of a one-side axle through solenoid valves 12B and 13B. When a remote switch 27 is then turned on, a relay X3 is actuated and the contact 37g of the relay X3 is closed. As a result, the contact 37g of the relay X3 acts as a holding circuit while the relay X3 is actuated even when the switch 27 is turned off. Therefore, a constant air pressure can be always applied to the brake circuit during braking operation until the vehicle reaches the C-car speed unless the air pressure is forcibly discontinued by means of the switch 27 or a K-testing switch 37b.
