摘要:
A positive resist composition comprising (A) a polymer comprising recurring units containing an acid labile group, recurring units having a lactone ring, and recurring units having an oxirane ring, the polymer being adapted to increase alkaline dissolution under the action of an acid, (B) a photoacid generator, and (C) a solvent forms a fine pattern with improved LWR, improved MEF, rectangular profile, and collapse resistance.
摘要:
A light-reflecting panel is proposed, provided with a constitution wherein a fine powder-containing polyester layer comprising an aliphatic polyester series resin and a fine powder filler is layered over one face or both faces of a metal plate, as a light-reflecting material, which is thin and allows for form-processing, provided with a high degree of reflection capability while at the same time preventing a decrease in reflectance due to ultraviolet irradiation. This light-reflecting material allows excellent light reflectivity to be obtained by refractive scatter due to a difference in the refractive indices of the aliphatic polyester series resin and the fine powder filler constituting the fine powder-containing polyester layer, is characterized by almost no decrease in reflectance due to ultraviolet irradiation occurs since the aliphatic polyester series resin constituting the fine powder-containing polyester layer does not have aromatic rings that absorb ultraviolet light, and can be made into a thin type light-reflecting panel since it can be layered directly onto a metal plate without using an adhesive.
摘要:
Herbicidal compositions containing as the active ingredients (one or more compounds selected from among light-induced herbicidal compounds and one or more compounds selected from among organoposphorus herbicidal compounds, characterized by containing ethylenediamine alkoxylates and alcohol alkoxylates as surfactants. These herbicidal compositions have an excellent rapid action and exert a remarkable herbicidal effect in a small dose.
摘要:
An instrumental error compensation circuit for a flow meter is disclosed in which a flow rate calculated from an output signal of the flow meter is identified with respect to a plurality of predetermined sections of flow rates. Flow rate compensation coefficients are calculated by linear interpolation on the basis of actually measured data which are obtained in advance in accordance with instrumental errors of the flow meter. Actual flow rates of a fluid are measured with the instrumental errors of the flow meter compensated for by the calculated coefficients.
