Title: Production of polyolefin particle containing organic peroxide adhering thereto
Inventor: TAIRA SUEHISA
IPC: C08L23/02
Filed: 1992-07-10
Abstract: PURPOSE:To evenly adhere an organic peroxide to polyolefin particles while preventing denaturation of the peroxide and inhibiting static buildup to thereby obtain the subject polyolefin particles having a narrow particle size distribution by adding the organic peroxide in a solid state to the particles and subjecting the mixture to specific treatments. CONSTITUTION:An organic peroxide which is solid at room temp., preferably one which does not rapidly decompose at its melting point [e.g. alpha,alpha-bis(t- butylperoxy)diisopropylbenzene], is added to particles of a polyolefin (e.g. PP). The mixture is heated to a temp. not lower than the melting point but below the temps. at which the peroxide rapidly decomposes. Thus, the peroxide is melted. Polyolefin particles cooled to below room temp., desirably -20 deg.C to below 5 deg.C, preferably -20 deg.C to 2 deg.C, are added to the resulting mixture to rapidly cool it to a temp. below the melting point of the peroxide.

Title: Device for pulling single crystal
Inventor: ABE HIROSHIGE
IPC: H01L21/208
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a device for pulling a single crystal which can control temperature fluctuation caused by the convection current of a melted liquid to improve the crystallization degree of the single crystal, by disposing a position for pulling the single crystal at a place shifted from the center of a magnetic field on the plane view of electromagnets. SOLUTION: Electromagnets 8, 9 are diposed on the periphery of a crucible 3, and, while the crucible 3 is rotated with the electromagnets 8, 9 under a cusp magnetic field, a single crystal 13 is formed on a seed crystal held at the lower end of a wire 7 and pulled. Therein, the electromagnets 8, 9 are disposed so that their magnetic field center G on the plane view is placed at a position (for example, 50 mm, when the inner diameter of the crucible is 790 mm) slightly shifted from the center O of the crucible 3. Therefore, when the single crystal 13 is pulled, the single crystal 13 is pulled from the center O of the crucible 3, but the position for pulling the single crystal 13 is slightly shifted from the magnetic field center G of the electromagnets 8, 9.  Thereby, a small magnetic field is generated at the position for pulling the single crystal 13, thus controlling the temperature oscillation of the melted liquid around the pulling position, and the distributions of oxygen concentration and resistance value on the surface of the wafer can be uniformed.

Abstract: PURPOSE:To prevent overlap of tracks by forming a track on a tape-shaped recording medium without overlapping the preceding track by a rotary head before the running speed of the recording medium reaches zero in accordance with an inverting command or a stop command. CONSTITUTION:In case of inversion or stop of running of a tape-shaped recording medium 10, the recording medium 10 is run at a speed higher than the steady speed in accordance with the inverting command or the stop command, and a track is formed on the recording medium 10 without overlapping the preceding track by rotary heads 15 and 16 before the running speed of the recording medium 10 reaches zero. For the purpose of forming the track in this manner, the recording medium 10 is temporarily increased and is reduced to zero in case of automatic inversion or automatic stop, and the speed is increased in the reverse direction to stably run the recording medium 10 in the reverse direction in case of automatic inversion. Thus, overlap of tracks is prevented and signals are not broken in case of automatic inversion or automatic stop.
