IPC: G09G3/36
Filed: 1988-10-18
Abstract: PURPOSE:To prevent picture deterioration at the time of reproducing a still picture by making constant the polarity of a picture signal to be held by a liquid crystal panel at the time of the still picture reproduction. CONSTITUTION:A still picture switch 7 is depressed to make the output (c) into 'L', simultaneously the output (c) is latched by a first FF 8 in the start-up of a control signal (b) from a control signal generation circuit 6, and the output (d) is synchronized with a vertical synchronization signal (a) to make into 'L'. Consequently, a first AND gate 10 prevents the passage of a control signal (f) inverting in every lines, polarity inverting switch 5 is fixed at a lower side, and the video signal of straight polarity is supplied to a Y drive circuit 3. Further, the output (d) of the first FF 8 is supplied to the second FF 9, an output (i) being previously latched is outputted, the said output (d) is changed from 'H' to 'L' by this output after one field from being made into 'L', and the passage of a shift clock (h) is prevented. Thus, a writing is executed with same polarity from the first vertical blanking period of a switch 7 depression on a liquid crystal panel 1.

IPC: G05B13/02
Filed: 1990-09-28
Abstract: PURPOSE:To suppress the influence of noise in D operation and to prevent a response from becoming an extremely vibrational signal by providing this auto-tuning controller with an automatic adjusting means for repeating the updating of a control parameter until a required response is obtained as the response of an output to be controlled while executing PID control by an updated PID parameter. CONSTITUTION:The auto-tuning controller 1 is provided with a proportional operation (P) part 2, an integrating operation (I) part 3, a differential operation (D) part 4, and an auto-tuning algorithm (control) part 5. While executing PID control by the P, I and D parts 2, 3, 4, the response of a plant 6 is measured and a control parameter is automatically controlled based upon a deviation (y) found out from a process variable and a set value(SV). Namely, a previously set y0 is the positive value of the (y) applying a condition for starting auto- tuning processing, and when the absolute value of (y) exceeds y0, the auto-tuning processing is started. Consequently, the response of the plant can be prevented from becoming a vibrational signal by the D operation even when noise or the like exists.

Title: Method for leading-in of optical fiber cable of composite overhead earth wire consisting of optical fiber
Inventor: SHIMOJIMA KIYOSHI
IPC: G02B6/44
Filed: 1984-12-12
Abstract: PURPOSE:To permit easy leading-in and replacement of an optical fiber cable by leading in the cable while oscillating the cable at a suitable frequency and acceleration. CONSTITUTION:The optical fiber cable 3 is led into a composite overhead earth wire 4 consisting of optical fibers by the traction of a take-off unit 9 from a drum 8 on which the optical fiber cable is wound. The cable 3 is oscillated at the suitable frequency and acceleration by an exciter 7 during the leading-in. The cable 3 oscillates in a protective pipe 2 of the wire 4 and is led into said wire under the relatively light traction force by the take-off unit 9 while moving zigzag. The replacement of the cable is thus executed. More specifically, the contact of the cable with the protective pipe is decreased by the oscillation applied to the cable from the exciter by which the frictional force during the movement in the protective pipe is decreased. Since the cable moves zigzag in the protective pipe owing to the change of the acceleration, the corrosive metallic powder and dust are carried to the outside of the pipe. The driving power of the take-off unit in the drawing operation is thus decreased and the leading-in is speeded up.

Filed: 1988-10-17
Abstract: PURPOSE:To redress the fault of a picture element caused by an abnormal semiconductor switching element and to prevent the deterioration in displaying quality by switching a changeover means to a delay means side every horizontal scanning term corresponding to the abnormal semiconductor switching element and delaying a video signal by prolongation term. CONSTITUTION:In the case of scanning a faulty horizontal scanning line Hd, the pulse width of a write pulse is set to become the pulse width 2t which is double ordinary pulse width (t) by a control circuit 16 and the common terminal (a) of a changeover switch 15 is switched to another terminal (c) side. Namely, the video signals inputted thereafter are delayed by the increasing amount of the write pulse which is given to the faulty horizontal scanning line Hd by passing through a line memory 14. Thus, the excellent conductive state of a faulty thin film transistor whose conductive state can not be made excellent with the ordinary pulse width (t) is obtained and the fault of the picture element caused by the faulty transistor is redressed. The adverse effect on a display screen is avoided by delaying the video signal by the increasing amount of the pulse width.

Abstract: PURPOSE:To suppress the transient ripple by the disposal in a short time by directly controlling the waveform with a predetermined value. CONSTITUTION:Supposing that the changeover is completed at 0 deg. of U phase, the changeover comes to be at the position of 180 deg. of V phase 60 deg. on this side.

Abstract: PROBLEM TO BE SOLVED: To synchronize three phases using a single sensor by synchronizing a biasing signal with a common signal indicative of the rotational position of a rotor and biasing the motor phase with three biasing signals where adjacent signals have a phase shift of 2π/3. SOLUTION: Biasing signals for windings B1-B3 are generated in response to a positional signal from a single sensor. Three magnetic sectors S1, S2, S3 make an angle of 60 deg. with the rotational axis of a wheel and arranged along the entire circumference of a rotor at a constant interval. When a three- phase motor is energized with three input signals having phase shift of 2π/3, the motor is started in two cases out of three cases but it is not started in the third case. When the motor is not started, energization of phase is shifted by 2π/3 thus starting the motor. According to the arrangement, number of rotor position sensor C can be decreased to one.
