A method for producing an α-olefin oligomer including: polymerizing in the presence of a catalyst one or more α-olefins having 6 to 20 carbon atoms to produce an α-olefin oligomer; and deactivating the catalyst by a deactivator from which oxygen is removed. A method for producing an α-olefin oligomer including: polymerizing in the presence of a catalyst one or more α-olefins having 6 to 20 carbon atoms to produce an α-olefin oligomer; and passing the reaction solution containing the α-olefin oligomer through a bag filter.

A polyolefin resin composition comprises a component A consisting of polypropylene or a propylene-ethylene block copolymer whose MFR is greater than 16 (g/10 minutes); a component B consisting of an ethylene based rubber; and a component D compatible with the component B. A ratio of summation of the propylene-ethylene copolymer part in the component A, the component B, and the component D to summation of the components A, B, and D is 25 wt. % or more and 45 wt. % or less. Further, a ratio of the blend quantity of the component D to summation of the blend quantities of the components B and D is less than 0.8. In this manner, the bending elastic modulus and the tensile breaking extension are included in a desired region, while the tensile breaking extension is improved.

A non-destructive method of determining substrate tilt within a packaged component includes providing the packaged component (10) with a component surface (32), providing a substrate (22) in the packaged component (10) wherein the substrate (22) has a substrate surface (33), using an acoustic wave (50) to measure a distance (34) between the component surface (32) and a region on the substrate surface (33), using another acoustic wave (53) to measure another distance (35) between the component surface (32) and a different region on the substrate surface (33), and comparing the distances (34, 35) to a threshold value.

An injection molding composition includes: 100 parts by weight of a propylene-ethylene copolymer comprising a crystalline portion and a non-crystalline portion; and 17 to 33 parts by weight of inorganic particles capable of imparting at least one of rigidity and heat resistance to the propylene-ethylene copolymer. The propylene-ethylene copolymer has a melt flow rate of 15 to 50 g/10 min and a molecular weight distribution (Mw/Mn) of not less than 5. A crystalline ethylene polymer contained in the crystalline portion and a non-crystalline propylene-ethylene copolymer contained in the non-crystalline portion have a total amount ranging from 10 to 20% by weight.
