A polymer particle produced by forming a layer of filler-free polymer (II) on the surface layer of a filler-containing polymer particle (I) by polymerization of a monomer composed mainly of an ethylenically unsaturated compound in the presence of the polymer particle (I) is suitable for uniformly carrying a biological substance such as an immunoreactive substance, enzyme or cell on its surface because it has no filler in its surface layer, and the physical properties of the filler contained in the polymer particle (I) can be utilized.

A substrate cooling device includes a cylindrical heat shielding member 30 configured to be movable between an insertion position where the heat shielding member 30 is inserted between the substrate holding member 15 in a processing vessel 11 and a heating member 12 and an unloading position where the heat shielding member 30 is unloaded from the insertion position, and configured to block radiant heat toward the substrates W after completing a heat treatment; and an air cooling port 21 provided at an outside of the processing vessel 11. The heat shielding member 30 includes two half-cylindrical members 31 that are assembled and separated at the unloading position, and is movable between the unloading position and the insertion position. An outer surface and an inner surface of the heat shielding member 30 are made of materials having a relatively low emissivity and a relatively high emissivity, respectively.

In a process for producing methacrolein by the gas phase catalytic reaction of isobutene with molecular oxygen in the presence of a catalyst consisting of Mo, Bi, Fe, Co, Sb and O, the catalyst is prepared by using as the Sb component, a mixture of a trivalent Sb compound and a pentavalent Sb compound. When said catalyst is used, the reaction can be continued over a long period of time without formation of complete oxidation products, i.e. CO and CO.sub.2, and, even when the starting isobutene contains n-butene, the reaction proceeds smoothly to make it possible to produce methacrolein and 1,3-butadiene simultaneously.

An ink jet printing apparatus and an ink jet printing method, whereby high-permeation ink and low-permeation ink are employed to prevent a reduction in optical density is provided. The ink jet printing apparatus controls ejection of ink from print heads, so that only low-permeation ink is ejected onto the edge area of a print medium that is adjacent to a non-printing area, and this time, high-permeation ink is not employed. Further, the ink jet printing apparatus controls ejection of ink from the print heads, so that both low-permeation ink and high-permeation ink are employed for the non-edge area that is adjacent to the edge area, and to perform printing, the low-permeation ink is ejected onto the non-edge area prior to the high-permeation ink.

A vapor-phase growing unit of this invention includes: a reaction container in which a substrate is arranged, a first gas-introducing part having a first gas-introducing tube in which a gas-spouting port opening in the reaction container is formed, the first gas-introducing part serving to supply into the reaction container a first gas consisting of an organic-metal including gas, and a second gas-introducing part having a second gas-introducing tube in which a gas-spouting port opening in the reaction container is formed, the second gas-introducing part serving to supply into the reaction container a second gas which reacts with the organic-metal including gas and whose density is smaller than that of the organic-metal including gas. The gas-spouting port of the first gas-introducing tube and the gas-spouting port of the second gas-introducing tube are arranged along an outside periphery of the substrate arranged in the reaction container.

摘要:
In the plasma processing by an electrically negative gas, the in-plane uniformity of plasma processing is enhanced compared to the conventional case by controlling the ion density in the plasma. Not only is a processing gas being an electrically negative gas introduced from a processing gas source 170 into a processing chamber 102 but also an electrically negative gas having electron attachment coefficient greater than that of the processing gas is introduced as an additional gas from an additional gas source 180 to thereby form a plasma. In the plasma formation, the ion density in the plasma is controlled by regulating the flow rate of the additional gas relative to that of the processing gas.
摘要:
An image-forming apparatus is provided for formation of a high-quality image without irregularity in the image density independently of the infiltration time of the pretreatment liquid or the delivery speed of the plain paper sheet for the printing. The interval between a pretreatment liquid applicator 30 and printing heads 21-24 is adjusted by a stepping motor 98 driven by a stepping motor control circuit 34 based on the delivery speed data read by a memory controller 68. Thereby an endless belt 90 is allowed to circulate in the direction of the arrow-C or arrow-D. This circulation movement of the endless belt displaces the applicator holder 82 or the pretreatment liquid applicator 30 at an intended distance in the arrow-A direction or the reverse direction along the guide rail 86,88.
摘要:
According to one embodiment, a process gas containing a fluorocarbon-based gas being an etch gas having a deposition property and SF6 gas as an additional gas are introduced into a process chamber, a plasma is generated in the process chamber, and an etching is performed on a silicon-containing oxide film formed on a substrate by using a resist pattern as a mask through the plasma. At this time, based on a relationship between an etch rate and a resist selectivity that is changed with respect to a change in a flow rate of the additional gas, the flow rate of the additional gas is set to a range of the flow rate in which changes in the etch rate and the resist selectivity accompanying an increase in the flow rate of the additional gas tend to increase.
