Abstract: A catalyst for olefin polymerization of the present invention includes a solid titanium catalyst component (I) including titanium, magnesium, halogen, and a cyclic ester compound (a) represented by the following formula (1): wherein n is an integer of 5 to 10; R2 and R3 are each independently COOR1 or R, and at least one of R2 and R3 is COOR1; a single bond (excluding Ca—Ca bonds, and a Ca—Cb bond in the case where R3 is R) in the cyclic backbone may be replaced with a double bond; a plurality of R1's are each independently a monovalent hydrocarbon group having 1 to 20 carbon atoms; and a plurality of R's are each independently a hydrogen atom or a substituent, but at least one of R's is not a hydrogen atom, and an organometal compound catalyst component (II). When this catalyst for olefin polymerization is used, an olefin polymer having a broad molecular weight distribution can be produced.

Abstract: Disclosed is a catalyst for olefin polymerization comprising [I] a solid titanium catalyst component [S] comprising titanium, magnesium, halogen and an electron donor (b), which is obtained by bringing a solid adduct consisting of a magnesium compound and an electron donor (a) into contact with an electron donor (b) and a liquid titanium compound by at least one method selected from (A) a method of contacting the materials in a suspended state in the coexistence of an inert hydrocarbon solvent and (B) a method of contacting the material plural times individed portions and [II] an organometallic compound catalyst component [M] containing a metal selected from the groups I to III in the periodic table.

Abstract: An electronic apparatus 20 is of a portable type and has a thin body integral with a display screen holdable by both hands HR, HL of a user for viewing purposes. Disposed on a front of the body 21 are a flat display panel 22 and various operation buttons 23–27, and first and second touch sensors 28 and 29. The first touch sensor 28 is disposed on the apparatus at a position where when the body 21 is held by both the hands of the user, a touch surface of the first sensor 28 is easily operated vertically by a finger of the user's right-hand HR whereas the second touch sensor 29 is disposed at a position where when the body 21 is held by both the hands of the user, its touch surface is easily operated horizontally by a finger of the user's left-hand HL.
