A propylene block copolymer with a high proportion of ethylene-propylene copolymer particles (rubber component) well dispersed in a propylene polymer exhibiting well-balanced rigidity and impact resistance can be obtained by using a solid catalyst for polymerization of olefins comprising (a) a solid catalyst component with controlled morphology, comprising magnesium, titanium, and a halogen atom, having an average particle diameter, specific surface area, and pore volume in a specific range, and having a pore size distribution in which an cumulative pore volume with a pore size of 100 Å or less is more than 50%, (b) an organoaluminum compound, and (c) an organosilicon compound. The block copolymer is very useful particularly for the application of vehicle parts such as a bumper and parts for household electric appliances.

A ball-shaped play equipment is provided that outputs voice in response to a shock and can be played in more diversified ways than ever. The play equipment comprises a conversion section 30 for converting external voice into first voice data, a first recording section 54 for recording the first voice data, a detection section 58 for detecting a shock applied to the equipment, and a reproduction section 40 for outputting voice based on the first voice data recorded in the first recording section 54 when the detection section 58 detects a shock. At least one of the conversion section 30 and the first recording section 54 is activated on condition that it receives a command signal. The equipment may further comprise an operation section 20 which is externally operable and a signal transmission section 52 which transmits a command signal to at least one of the conversion section and the first recording section according to an operation applied to the operation section 20.
