Abstract: Provided is a monomer composition containing methyl methacrylate and methyl propionate, in which the methyl propionate content is more than 200 ppm by mass and 50,000 ppm by mass or less relative to the total mass of the monomer composition.

Abstract: Provided is a monomer composition containing methyl methacrylate, and at least one compound of methyl pyruvate and methyl 2-methylbutyrate.

Abstract: An electronic messaging method comprises, in respect of a message received from a purported sender, determining if a blockchain transaction identifier is appended to the message, and comparing a hash created from the message body, the purported identity of the sender and the identity of the recipient with a hash stored on a blockchain network identified by the blockchain transaction identifier. When the created hash does not match with the stored hash, the received message is determined to be not from the purported sender. When the created hash matches the stored hash, the method may check a blockchain address registry associated with the blockchain network to determine if a blockchain address corresponding to the blockchain transaction identifier has an associated valid address in the blockchain address registry. A receipt transaction may be committed to the blockchain network in respect of the received message.

Abstract: The gas spring includes a cylindrical cylinder body that stores gas, a piston body that partitions the inside of the cylinder body into a rod-side gas chamber and a piston-side gas chamber as having a flow path capable of allowing gas flow between the rod-side gas chamber and the piston-side gas chamber, a rod body that is connected to the piston body as having a hollow portion, a push rod that moves in the axial direction of the rod body with operation of an operator as being inserted to the hollow portion of the rod body, and a valve that the flow path with movement in the axial direction in the piston body as being arranged separately from the push rod and movable with the push rod.

Abstract: A filter includes upper and lower filter members that form at least two opposed surfaces that face each other, a porous member contained in the filter member, and a coupling member having an opening that is open to the porous member so that the porous member communicates with the coupling member. In the filter, the filter member removes foreign matters contained in liquid, and the liquid from which the foreign matters are removed is discharged through the porous member and the coupling member.

Abstract: A vacuum cleaner includes an electric blower generating the suction force; a suction port body on which the suction force of the electric blower acts and which sucks in the dust on the surface to be cleaned; and a centrifugal force dust collection section to collect the dust from the suction port body. The electric blower includes a fan section and a low input type motor to drive the fan section.

Abstract: A filter is composed of a filter member forming at least two opposed faces, an inner space surrounded by the filter member for accumulation of a liquid, and a coupling member establishing communication between the inner space and the outside to discharge the liquid in the inner space to the outside. The liquid flows through the filter member, is thereby removed of foreign matters, and is discharged via the coupling member. Convexo-concaves are provided on at least one face of the filter member.

Abstract: A fuel filtration device includes a filter medium in which at least two opposing surfaces are formed, an inner portion space that is surrounded by the filter medium and where liquid accumulates, and a connecting member that connects the inner portion space and the outer portion and delivers the liquid in the inner portion space to the outer portion. The filter medium is a non-woven fabric made of material fibers and adhesive fibers, and by melting the adhesive fibers, the fibers are joined.

Abstract: The present disclosure concerns an intra-line fishing rod with at least one fishing line guide member inserted therein. According to the present invention, maintenance of fishing line guide members is facilitated. Support members S1,S2,S3,S4 are mounted inside a rod pipe while respectively supporting fishing line guide members G1,G2,G3,G4 which allow a fishing line to slide smoothly therethrough. The support members and fishing line guide members are positioned and removably mounted inside the rod pipe.

Abstract: A patch for preventing carburization, nitriding or oxidation comprises:a film comprising a heat-fusible or heat-meltable particulate material having an anti-carburizing, anti-nitriding or anti-oxidizing effect and a heat-decomposable resin as a binder; anda heat-resistant silicone pressure sensitive adhesive, which is decomposed at a carburizing, nitriding or oxidizing temperature, provided on one side of the film.

Abstract: The present invention provides a wind deflector for a sunroof which has a deflector panel rotatably mounted on a roof through hinges each including a first hinge piece and a second hinge piece pivotally connected to each other through a hinge pin forward of the front end of an opening in a roof, the first and second hinge pieces extending downwardly to a position above a rain gutter under the opening in the roof. As a result, the invention significantly reduce the level of wind throb and wind noise and prevents rainwater from entering into the passenger compartment of a vehicle.
