In a thermal processing apparatus irradiating a substrate with light from a lamp for heating the substrate, an opening is formed in a reflector for mounting a camera unit. The camera unit images three portions of an auxiliary ring supporting the substrate, for obtaining the position of the center of the auxiliary ring before the thermal processing apparatus receives the substrate therein. The camera unit further images the substrate for obtaining the position of the center of the substrate before the thermal processing apparatus receives the substrate therein and places the same on the auxiliary ring. The thermal processing apparatus moves the substrate so that the center thereof coincides with the center of the auxiliary ring, and thereafter places the former on the latter. Thus, the auxiliary ring can be so designed as to reduce overlaps of the auxiliary ring and the outer edge of the substrate while the overlaps can be rendered uniform over the entire circumference of the substrate for improving temperature uniformity of the substrate.

The invention discloses a preparation method for a nano-zinc oxide modified graphene hybrid material. The method includes: preparing a graphene oxide suspension solution; dissolving a zinc salt in water, adding the solution into the graphene oxide suspension solution, conducting ultrasonic treatment, adding an alkali reagent dropwise to obtain a zinc hydroxide graphene oxide suspension solution; under ultraviolet light irradiation, performing static aging to obtain a zinc hydroxide-graphene oxide gel, adding an excessive reducing agent, carrying out reaction, using water and ethanol to conduct repeated washing, and performing drying to obtain a zinc hydroxide-graphene dry gel; placing the gel in a muffle furnace, and conducting treatment at high temperature to obtain the gray nano-zinc oxide modified graphene hybrid material. The nano-zinc oxide obtained by the invention has a large specific surface area, can effectively promote vulcanization crosslinking, greatly reduces the using amount of zinc oxide, and is of great importance to full utilization of zinc resources and ecological economy. At the same time, without affecting the performance of graphene, the method is in favor of further expanding the potential application scope of graphene.

The invention relates to a preparation method of a Ziegler-Natta catalyst for efficiently preparing low entanglement polyethylene and an application. The preparation method comprises the following steps that a prepared alcohol absorbing porous carrier and a prepared polyhedral oligomeric silsesquioxane molecule / Mg mixture are stirred in tetrahydrofuran and filtered, solid powder is dried until the solid powder flows freely, and a carrier used for preparing the low entanglement polyethylene catalyst is obtained; then, a carrier of an aluminium alkyl modified catalyst is prepared through the aluminium alkyl; and finally, a TiC14 tetrahydrofuran solution is added into the carrier of the aluminium alkyl modified catalyst, after stirring, the solid powder is washed by means of the tetrahydrofuran solution and dried until the solid powder flows freely, and the Ziegler-Natta catalyst for efficiently preparing the low entanglement polyethylene is obtained. POSS can be assembled into a microsphere with particle diameter being 20-100 nm in a pore passage of the porous carrier. The active points are divided effectively. The intervals between active centers are increased. The occurrence of chain overlapping in the polymerization process is restrained. The low entanglement polyethylene Ziegler-Natta can be prepared efficiently with the polymerizing temperature being higher than or equal to 60 DEG C.

The objective of the present invention is to eliminate the generation of burrs in a press-formed product even with a configuration in which a high-temperature blank material is subjected to a trimmingprocess, thereby eliminating a burr removal operation performed after forming, and thus achieving a reduction in work man-hours and by extension a reduction in cost. In a press-forming process in which a blank material 3 is shaped while a die 1 is being clamped against a punch 2, a trim part 3a is sandwiched between a trim holding stepped portion 6 and a cut holder 8 while an elastic force of a spring component 9 is being imparted thereto. As a press-forming action of the die 1 progresses, a trimming blade 7 moves in a relative manner along an outer peripheral edge portion 5b of a punch sideforming surface portion 5, while the cut holder 8 is being subjected to a pressing force of the trim holding stepped portion 6, counteracting the elastic force of the spring component 9, and in this way the trim part 3a is cut off by being sheared between the trimming blade 7 and a tip end corner portion 5c of the outer peripheral edge portion 5b of the punch side forming surface portion 5.

A detection method for detecting a detection target substance is provided. The method includes a first application step of applying a magnetic field a liquid suspension to link a plurality of magnetic particles in a row from an interior surface of a liquid receiving member that receives the liquid suspension of magnetic particles to which a detection target substance is bound, a second application step of bringing the linked magnetic particles near the interior surface while the magnetic field is applied to the liquid suspension, and a detection step of detecting the detection target substance bound to the magnetic particles brought near the interior surface by the second application step, wherein the direction of the magnetic field applied to the liquid suspension is altered so the linked magnetic particles approach the interior surface in the second application step.
