Abstract: An electrode manufacturing method includes a first step of applying an electrode liquid composition in a desired shape at a desired position on a substrate, the electrode liquid composition containing an electrode mixture material; a second step of acquiring positional information as to where the electrode liquid composition is applied; and a third step of cutting only the substrate at a desired position in a region other than an electrode mixture material region where the electrode liquid composition is applied to obtain an electrode cut out in a desired shape.

Abstract: In a mask device with blower, a sensor for warning is disposed, which detects a movement position of an exhaust valve corresponding to the case where an internal pressure of a face body is lower than an outer atmospheric pressure at the time of inhaling air in a non-contact state and outputs a signal. A warning device operates in accordance with a signal that is output from the sensor for warning.

Abstract: An inhalation opening 6 and an exhalation-opening 4 are formed in the facepiece 2 of a breathing apparatus 1 and the openings can be closed with an inhalation valve 8 and exhalation valve 7, respectively. If a person wearing the breathing apparatus 1 inhales, the inhalation valve 8 is open and the exhalation valve 7 is closed. A photointerrupter 11 senses the closing operation of the exhalation valve 7 and supplies electric power to a motor 9 to drive a blower 16.

Abstract: The present invention relates to an aqueous dispersion of a polymer composition comprising (A) a copolymer which comprises (a.sub.1) a unit derived from a vinyl monomer having a hydrolyzable silyl group and (a.sub.2) a unit derived from another vinyl monomer copolymerizable with (a.sub.1), and (B) a water-soluble polymer having an amineimide group. The aqueous dispersion of the present invention has good polymerization stability, mechanical stability and storage stability, and is useful in various applications such as coating materials, paints, adhesives, primers and binders.

Abstract: In a roller chain having a seal between inner and outer link plates, an encircling member is provided which surrounds the seal to reduce entry of foreign particles and maintain minimum separation between the link plates.

Abstract: A link assembly for a chain comprising a link portion, a top plate portion having a top surface and a bottom surface made of a predetermined first material, and a plate member made of a different material than the top plate portion and integrally molded to at least the one of the top or bottom surfaces of the top plate portion.

Abstract: A reactive vinyl polymer containing units derived from a vinyl monomer (A) having a hydrolyzable silyl group and units derived from a vinyl monomer (B) having an aminimide group, in which the polymer obtained is used in preparation of dispersions suitable for coating of substrates to provide a tough, water-resistant film which optionally has a rust inhibiting effect on the substrate, if needed.
