Abstract: PURPOSE:To correct a contour of a video image to be thin and steep and to obtain an easy to see pattern by retarding a differentiating signal, rectifying and multiplying the signal to obtain a thinner 2nd order differentiating signal. CONSTITUTION:In order to make the width of a 1st order differentiating signal (b) narrow, after the 1st order differentiating signal (b) is obtained by a conventional method, the 1st order differentiating signal (b) is retarded by a delay circuit 2 to obtain a delayed 1st order differentiating signal (c).

Abstract: PROBLEM TO BE SOLVED: To provide an information encoding method, a decoding method, and a digital information storage device which make it possible to store as much information as possible even when the same head and the same medium are used since the capacity of digital information storage increases. SOLUTION: A magnetic storage system 10 decode a binary input signal 12 into a ternary code 16 of a code rate l, and a recording logic part 18 converts the ternary code into three states of 1, 0, and AC, which are recorded on a medium 28 by a conventional recording head on a saturation basis. A signal 32 read out by a conventional reproducing head 30 is amplified, and then detected as a digital ternary signal 40 by a detector 38, and a decoder 42 converts it into a binary signal. Therefore, high S/N and information density equal to that of binary saturation recording are obtained by the saturation recording. The convolutional code of the rate 1 is used, and therefore information recorded on the medium by using absolutely minimum code symbols can be encoded while given redundancy to simplify timing control.

Abstract: PURPOSE:To ensure the normal operation of an actuator since control has started by supplying a driving signal to the actuator and operating it in a yet longer period in control before the damping control by means of a controller. CONSTITUTION:A springing acceleration sensor 80 and a relative displacement sensor 82 provided in each wheel are installed there, and each of signals out of these sensors is inputted into a controller 60 together with a signal of a car speed sensor 84 by way of a differentiator circuit 86. This controller 60 utilizes a central processing unit 70, a read-only memory 72 and a random access memory 74, judging an oil temperature of operating oil in a shock absorber just after a traveling start at each time, and in the case where temperature is low, any damping force control is prohibited and, after it is so judged that the temperature is not low, the predriving of a step motor 40 varying a damping force characteristic of the shock absorber is carried out. a driving signal in this case should be set to a yet longer period than that of the damping force control. Accordingly, there is no hindrance due to low oil temperature or the like, and thus accurate operation in an actuator is securable from the outset of the damping force control.
