Abstract: PROBLEM TO BE SOLVED: To enable stopping of expansion/shrinkage of a mandrel on the way of coiling a metallic strip with a simple mechanism by restricting or releasing a stopper fixed to a rod with a pushing member fixed to a main shaft. SOLUTION: In a coiling device for the metallic strip, a plate-like stopper 9 is fixed to a fixed position of the rod 4 in which a tip pyramid 3 is inserted into the mandrel 19. A stopping means 10 for stopping the movement of the rod 4 by cooperating with this stopper 9 is fixed to the main shaft 7 covering the rod 4 and rotated together with the main shaft 7. The stopping means 10 is formed with a pushing member and an attaching/detaching means 13.

Here, it is provided that Z is equal to e<jwt> and F(Z) is a rational function of (Z). The attenuation factor, which is proportion to the real number field of F(Z), can be veried by varying proportion coefficient K. Transforming the above equation results in H(Z)=Ho[1+{(-2aoK)/ (1+aoK)+ (-2KF1(Z))/(1+aoK)}/{1+(KF1(Z)/(1+aoK)}]. Here, ao is the constant term of the numerator of F(Z), and any constant term of F1(Z) is not included in the numerator of F1(Z). This equation is realized by multiplier 11 of coefficient Ho, adder 21, block 6 realizing transfer function F1(Z), and  multipliers 51 to 54 of coefficients K/(1+aoK), -2ao, -1, and -2. Block 6 consists  of delay units 61 and 62, multipliers 63 to 66, and adders 67 and 68.

Abstract: PURPOSE:To reduce a necessary area of a semiconductor chip by providing other transistor which has connected the gate to a connecting point of the drain of two transistors and has connected the source and the drain in common to the second power source, and a CMOS invertor. CONSTITUTION:The titled circuit is provided with a transistor (TR) 1 of P channel whose gate and source are connected to the first power source VDD, and a TR2 whose gate and the source are connected to the power source VDD and in which the TR1 and the drain are connected in common. When a power source VSS is ''0''V and the power source VDD is applied, a charge is accumulated in a TR3 through the TR2, and an output end N2 of a CMOS invertor 4 whose input end is connected to the first joint N1 rises simultaneously when the power source VDD turns on, and it is inverted and falls when the joint N1 exceeds the threshold voltage of the invertor 4, therefore, a reset signal is outputted.

In this case, a voltage of an output end N2 becomes constant. Whenever the power source VDD is connected and disconnected, these operations are repeated.
