Abstract: PROBLEM TO BE SOLVED: To improve the balance between impact strength and rigidity of a propylene-ethylene block copolymer by causing a halogen compd. to be present in the step of propylene-ethylene copolymn. conducted in the presence of a catalyst comprising a solid component contg. Mg, Ti, a halogen, and an electron- donating compd., two aluminum compds. different in electronegativity from each other, and an alkoxysilane compd. SOLUTION: The solid component is prepd. by bringing a magnesium compd., a titanium compd., an electron-donating compd., and a halogen compd. into contact with each other. In one of the aluminum compds., the sum of Pauling's electronegativities of atoms bonded to one Al atom is lower than 8; and in the other, the sum is 8 or higher. The alkoxysilane compd. is represented by formula I (wherein R<1> is 1-6C alkyl or cycloalkyl; R<2> is 1-6C alkyl, alkenyl, or alkynyl; and 1<=s<=3). The halogen compds. present in the copolymn. step is represented by formula II (wherein Met is a metal atom; X is halogen; and n is the valence of Met).

Abstract: PURPOSE: To detect the application of abnormal external forces on a motor shaft  and to control the motor by performing logical judgement of the magnitude and  direction of the current of a DC motor and the magnitude and the direction of the  differentiated value of a speed signal.  
     CONSTITUTION: A reference signal I 0  is given to one terminal of a comparator 4 and one terminal of a comparator 6, and a motor-current signal 1 is applied to the other terminals of the comparators. Each output signal of the comparators are applied to one terminal of an AND gate 8 and one terminal of an AND gate 10. A rotating speed V of the motor is supplied to a differentiator 16, and its output accerelation- speed signal 2 is applied to a positive coding circuit 18 and negative coding circuit 20. The output signals from said coding circuits are applied to the other terminals of the AND gates 8 and 10. Therefore, the AND gate 8 sends out a logic "1", when the motor current I is larger than I 0  and the acceration 2 is negative; and sends out a "0" in the other case. The AND gate 10 performs the same logical judgment, thereby the specified logic output is obtained. When the output of an OR gate 12 is a logic "1", abnormal-collision condition is indicated.
