Abstract: A pneumatic tire comprises a sidewall portion is provided in the outer surface with a circumferentially continuous or discontinuous serrated zone in which radially extending serration ridges are arranged circumferentially of the tire. The serration ridges are grouped into circumferentially successively arranged groups each consisting of serration ridges whose angles ? with respect to the respective tire radial directions are different from each other, and gradually increased toward one circumferential direction. Each group has an equally-spaced position at which the serration ridges are equally spaced in the tire circumferential direction.

Abstract: A controller of a heat treatment apparatus forms a phosphorous-doped polysilicon film (D-poly film) on a semiconductor wafer, and determines whether the D-poly film satisfies a target heat treatment characteristic. When it is determined that the target heat treatment characteristic is not satisfied, the controller calculates a temperature in a reaction tube and flow rates of process gas supply pipes, which satisfy the target heat treatment characteristic, based on a heat treatment characteristic of the D-poly film and a model indicating relationships between changes in the temperature in the reaction tube and the flow rates of the process gas supply pipes, and a change in a heat treatment characteristic. The controller forms the D-poly film on the semiconductor wafer according to heat treatment conditions including the calculated temperature and the calculated flow rates, so as to satisfy the target heat treatment characteristic.

Abstract: Magnesium hydroxide having a high aspect ratio, a production method thereof and a resin composition comprising the same. The method of producing the magnesium hydroxide having a long diameter (width) of not less than 0.5 pm and aspect ratio of not less than 10, comprising the steps of: (A) adding an alkali to and coprecipitating it with a mixed aqueous solution of a water-soluble magnesium salt and a monovalent organic acid or a salt thereof, or (B) adding an alkali aqueous solution to and coprecipitating it with an aqueous solution of a water-soluble magnesium salt and adding a monovalent organic acid or a salt thereof to the resulting product; and (C) hydrothermally treating the obtained slurry at 100° C. or higher.

Abstract: A pneumatic tire comprises a sidewall portion provided in the outer surface thereof with an embossed mark. The embossed mark has a top surface axially outwardly away from the outer surface, a side surface extending from the outer surface to the top surface, an outside edge at which the side surface intersects with the top surface to form an outside corner, and an inside edge at which the side surface intersects with the outer surface to form an inside corner. The outside edge has a circumferential segment extending parallel with the tire circumferential direction, and the inside edge has a nearly-circumferential segment positioned oppositely to the circumferential segment and extending at an angle of from 0.5 to 2.5 degrees so that a warped plane is formed between the circumferential segment and nearly-circumferential segment.

Abstract: The present invention relates to a filler for inhibiting foaming caused due to CO2, which comprises hydrotalcite compound particles and calcium hydroxide particles and/or magnesium hydroxide particles, the use of the filler in a synthetic resin, and a shaped article formed therefrom, more particularly to a filler for inhibiting foaming, which is obtained by incorporating, into hydrotalcite compound particles represented by the following chemical structural formula (1): [(Mg2+)y(M12+)(1-y)]1-xM3+x(OH)2CO32?.mH2O??(Formula 1) (wherein M12+ represents a bivalent metal, M3+ represents at least one trivalent metal, and x, y, and m represent valences satisfying the relationships: 0<x<0.

Abstract: A pneumatic tire is provided with center blocks defined by a central main groove, shoulder main grooves and central axial grooves, and shoulder blocks defined by the shoulder main grooves, shoulder axial grooves and the tread edges. The tread profile comprises a center arc of a radius of 250 to 550 mm and a shoulder arc of a smaller radius and has a camber quantity of 5.5 to 9.0 mm. The center blocks and shoulder blocks are provided with sipes each having an axially outer open end and an axially inner closed end disposed at specific positions in relation to the axially inwardly adjacent main grooves. The total sipe number on the shoulder blocks is more than the total sipe number on the center blocks.

Abstract: A sensor protector adapted to be attached to either a body or a door of a vehicle includes a hollow portion for accommodating a touch sensor for sensing whether or not an object exists between the body and the door of the vehicle, an attaching base portion formed as a unit with the hollow portion and including a core material embedded therein, a recessed portion provided at the attaching base portion having a rectangular shape formed by cutting out the attaching base portion, plural block-shaped cover portions formed contiguously with respective cut surfaces of the attaching base portion for covering the respective cut surfaces, and mating plates provided at two cover portions formed contiguously with respective visible front walls of the attaching base portion, the mating plates having facing mating edges which mate together when the sensor protector is bent.
